(1) Industrial chain of smart light pole system
The smart light pole system mainly realizes the integration of various smart devices and sensing devices and comprehensively utilizes wired and wireless transmission technologies to construct the network layer. Urban applications provide a solid foundation. Based on the combination of software and hardware and the integration of multiple technologies, the smart light pole system architecture can be divided into a terminal layer, network layer, platform layer, and application layer with reference to the layered theory of communication and Internet of Things. The terminal layer includes functional modules such as intelligent lighting, communication base stations, micro-meteorological monitoring, video collection, Wi-Fi coverage, LED information display, public broadcasting, and charging piles; the network layer includes communication networks, the Internet and the Internet of Things; the platform layer refers to The IoT platform and data platform realize intelligence through the platform; the application layer includes digital urban management, safe city, smart transportation, convenience services, environmental monitoring, and energy-saving control. It can be seen that the trend of cross-border integration of smart light poles is obvious. It consists of poles, management platforms/control terminals, LED lighting, video capture, micro stations, display screens, sensors, public WiFi, public broadcasting, charging piles, 5G roadside units, Operators, State Grid, China Tower, Huawei/ZTE, Alibaba/Tencent, gateways/servers, power supply/connectors, construction and operation and maintenance, planning and design and other enterprises (units) participated, forming a relatively complex industrial chain.
The materials and processes for the manufacture of smart light poles should meet safety and functional requirements, and ensure sufficient strength, stiffness and stability. At present, street light poles can be divided into two categories according to the material of the pole body: one is the steel street light pole, which is made of high-quality Q235 steel, and the exterior is sprayed with anti-corrosion and hot-dip galvanized. The aluminum alloy street light pole is made of high-strength aluminum alloy, which has super corrosion resistance. Aluminum alloy is easier to process than pure aluminum, has high durability, wide application range and good decorative effect.
Valmont Industries is a representative company of steel rods, headquartered in the United States. In 1994, it entered China and established Valemount Industrial (China) Co., Ltd., located in Songjiang Industrial Development Zone, Shanghai, with a registered capital of 17.15 million US dollars. It was officially put into operation in 1996. It mainly produces lighting poles, transmission and transformation poles, substation structures, communication poles and irrigation equipment and other products. Valmont has invested in 3 new factories in China (Shanghai, Guangdong Heshan, Shandong Haiyang), with a total investment of more than 46.65 million US dollars.

Morquez light poles are major events and government cooperation projects, such as the Youth Olympic Games, Beijing APCE Conference, etc., and are exported to all over the world.
According to the nature of the enterprise, it can be divided into three categories –
One is the traditional lamp pole enterprises, mainly concentrated in Jinan (representing Jinan Samsung), Yangzhou, Sichuan (representing Sichuan Huati, Deyang Hengda Lamps, etc.) and other places. Taking Yangzhou as an example, as China’s main outdoor lighting production base, there are nearly a thousand street lamps and related enterprises in Yangzhou, mainly concentrated in Gaoyou, Yizheng and other places, with a complete industrial chain. The main enterprises are Longteng Lighting, Chengxu Electric, Jiangsu Haowei Transportation Group Co., Ltd., Jiangsu Volt Lighting, Jiangsu Xiongye, Yangzhou Runqi, etc.
One is the companies that used to be communication towers, such as Shuzhi Technology (Beijing Meitainuo), National Dynamics Network Communication Group, Jilin Shenghao Communication Group, Zhejiang Juhua, Zhejiang Tayuan, Zhongke Yuantong (Beijing), Beijing Maiya Fangyuan, Zhejiang Ningyuan Tower Mast, Zhejiang Debao, etc. The predecessor of Shuzhi Technology was Beijing Metainuo Communication Infrastructure Investment Co., Ltd., which was established on April 3, 2009 with a registered capital of 196.0784 million yuan. Site management services for large operators and other customers in the society; at the same time, it provides comprehensive management and control solutions based on information infrastructure such as innovative and intelligent Internet of Things.
One is the companies that originally made flagpoles, such as Wuxi Nantian, Nanjing Huateng, Zhejiang Longqi, Beijing Dongfangqilong, Yaolong Flagpole, Luoyang Tianli Tower, Haichengyi, Shandong Derun, Hebei Guohua, Hebei Wanxin , Fangshan Zhengfeng, etc. Take Wuxi Nantian Safety Facilities Co., Ltd. as an example. The company was founded in 1995 and is a wholly-owned company of Hong Kong-based Mericat International in China. The leading products are stainless steel tapered flagpoles, aluminum alloy seamless tapered flagpoles, aluminum alloy light poles, traffic guardrails, etc. The conical flagpole is the selected product of the Qingdao Games in Singapore, the Universiade in Shenzhen, the Beijing Olympic Games and the Shanghai World Expo.
Management platform/control terminal
Most of the system integrators in the original smart city are from the background of state-owned enterprises. With the trend of the country building digital cities and smart cities, they have extensive government resources. For example, the 50th Institute of China Electronics Technology (Wu00 Shengtong), Yantai Haiyi Software Co., Ltd., Guangdong Zhuowei Network Co., Ltd., Shenzhen Aoguan Software Co., Ltd., Wuhan Zhongdi Digital Technology Co., Ltd., Wuhan Optics Valley Information Technology Co., Ltd., Jiangxi Shiheng Information Industry Co., Ltd., Netpower Technology Co., Ltd., etc.
The management platform realizes the unified management of a variety of smart devices and sensing devices integrated by smart light poles, and realizes the collaborative work of devices based on different application scenarios. It should also realize functions such as big data display and multi-subsystem linkage. At the same time, the platform should have expansion and integration functions, and can provide open software interfaces, mainly including video, temperature and humidity, security data, charging piles and other interfaces. At present, the main participating companies in the smart light pole industry chain basically have developed their own control platforms. Lighting companies have expanded based on the original lighting control system, adding functional management modules such as display, security, parking management, etc. Shanghai Sansi and Unilumin Technology have their own control platforms; Professional lighting management platform and control terminal enterprises such as Control, Zhilian Xintong, Zhichuang Energy, Dayun IoT, Jinan Taihua Wisdom, Shunzhou Technology, and Bixian IoT; video capture manufacturers such as Haikang and Dahua, Huawei , ZTE, Datang and other micro-station enterprises, and charging pile enterprises such as Tedian and Beijing Huashang Sanyou also have their own relevant management platforms.
In addition, Internet and communication companies are good at software development and data analysis, and their focus is also on software development, mainly on the development of smart city-level control platforms. On the whole, the current main control platform is only to realize the management and control of each functional module, and the linkage between modules is relatively small. To realize the subsequent big data analysis, and truly achieve the goal of “smart light pole”, it still needs more attention. long time and accumulation. Therefore, the next focus has gradually shifted from basic construction content such as establishing standards, consolidating foundations, and building computing power to cross-industry integration and big data applications. How to break industry barriers, integrate more urban data resources, and respond to various business application needs more efficiently and accurately at the level of artificial intelligence and big data, and gradually form a “speaking with data, making decisions with data, managing with data, and using data”. The new model of “smart light pole” construction based on data innovation is the trend of future control platform development.
The main LED road lighting companies are Signify (Philips), Huapu Yongming, Shanghai Sansi, Unilumin Technology, Sichuan Huati, Cinda Optoelectronics, Jingri Lighting, Jinghe Optoelectronics, Huzhou Mingshuo, Guangdong Hongbao, etc. Among them, Shanghai Sansi, Unilumin Technology, and Sichuan Huati have accumulated a lot of smart light pole engineering projects.
The installation rate of cameras on smart light poles reaches 30-50%, which is a hardware device with a high installation rate. Compared with traditional street light companies, security companies have been involved in the overall smart light pole solution for a shorter time, but larger security companies such as Dahua are already providing complete smart light pole solutions for tower companies, three major operators and the government. Security companies have advantages over lighting companies in smart cities, especially in the development and use of urban security data. Smart light poles are a branch of smart cities. They are not only lighting, but also need to use data for interaction such as snapshots of dangerous situations and information display. Security companies have long been familiar with this aspect. Hikvision and Dahua are the main providers of camera equipment for smart light poles. At the same time, both Hikvision and Dahua have launched their own smart light poles. Other companies include Zhejiang Yushi, Suzhou Keda and so on.
In terms of video capture system, in addition to traditional superior enterprises such as Hikvision and Dahua, with the development of artificial intelligence and big data technology, SenseTime, Megvii, Uniview, Suzhou Keda, Shanghai Yitu have emerged. , Yuncong Technology, Shenzhen Institute of Advanced Technology, Chinese Academy of Sciences and other enterprises focusing on back-end video data processing.
The large bandwidth of 5G means that telecom operators need greater transmission and forwarding capabilities. At the same time, the high frequency of 5G makes its signal penetration ability weaker than that of 4G signals. A large number of 5G micro base stations are built in application scenarios such as factories and parks to meet the needs of enterprise users.
At present, in the field of macro base stations, the global market has been divided up by Huawei, ZTE, Nokia and Ericsson. Huawei and ZTE have also successively released small and micro station products since 4G. In February 2019, Shanghai deployed a 5G network in Hongqiao Railway Station, and China Mobile Shanghai adopted Huawei’s 5G indoor solution. In January, Guangzhou Unicom also used Huawei’s indoor 5G solution, making Baiyun Airport the first airport in China covered by a 5G signal network. ZTE’s small cell series products include outdoor integrated Micro station, outdoor Pad RRU, indoor Pico station, indoor Femto/Nano station and indoor Qcell series products, etc., providing end-to-end small cell solutions, the products range from femtocell, picocell to Qcell’s distributed wireless solution for large enterprises and public spaces, supports heterogeneous networks and plug-and-play installations, and the latest Qcell also supports mobile edge computing.
The application of 5G is significantly different from 4G and 3G. Due to large bandwidth, low latency and massive coverage, 5G applications must be dominated by 2B (for enterprises), such as autonomous driving, telemedicine and distance education.
At the same time, in the 5G era, 5G technology and WiFi have a trend of integration, and companies with traditional advantages in the WiFi field, such as H3C and Shanghai Huanchuang, also have the will and opportunity to enter this market.
The smart light pole system is an important entry point for LED display companies to participate in the construction and application of smart cities. On the smart light pole, the installation rate of LED screens reaches 10-30%, breaking through the boundaries of the original LED products in terms of product function and form. Its function is not only a broadcast carrier, but also a big data value chain on this basis. The node that senses and collects data on the link. At present, the LED light pole screen is a customized product. Different styles are designed according to different project requirements and equipped with different functions (light sensor probe, monitoring, audio, face recognition), which can account for up to 50% of the cost of the entire light pole. Shanghai Sansi and Unilumin Technology independently produce LED light pole screens for their own smart light poles; JYLED’s LED light pole screens are widely used, and projects in Shenyang, Tianjin, Guangzhou, Changsha and other places also use their LED lights Stick screen products, and establish partnerships with ZTE, Huawei, Hikvision, Dahua, Poly Group and other companies.

The communication properties of smart light poles make operators try to enter the game. China’s basic network service providers are mainly the three major operators, namely China Mobile, China Unicom and China Telecom. The three major telecom operators have incomparable advantages in the field of network infrastructure. They are the pipeline of the network and the pipeline of data. . Judging from the data integration efforts and investment resources of the three major operators, intelligence will become the mainstream trend. As a “data pipeline” provider, operators have the inherent advantage of developing big data. Data pipelines are the foundation of all Internets, and operators can obtain almost all information on the Internet based on “network portals”.
The three major operators are mainly involved in the construction of the smart light pole communication network for the purpose of their networking layout. Most of the smart light poles are located on the important roads in the core area of the city, and the distribution is continuous, the geographical location is superior, and the demand for surrounding communication resources is strong; the smart light poles are positioned as urban and rural infrastructure, and are invested and constructed by the local government, without the need for communication operators to pay for location selection , compensation and engineering construction costs, the site acquisition cost is low; the height of the communication facilities given by the municipal comprehensive pole is generally distributed between 10 and 20 meters, which is extremely suitable for the deployment of the current LTE and future 5G microcell base stations. Smart light poles have opened a new window for the deployment of communication base stations. Operators can enjoy the policy dividends brought by municipal projects such as “multi-pole integration”, and can quickly and massively obtain municipal comprehensive pole site resources at a lower cost, and cooperate with roads. Peripheral communication base stations, optimize the existing network structure, lay a solid foundation for the high-density deployment of 5G base stations in the future, and reserve high-quality communication site resources.
In the development of smart light poles, on the one hand, the State Grid is a supplier of infrastructure such as power supply and smart pipe gallery, providing basic power and line laying pipelines for smart light poles; on the other hand, according to relevant statistics, the national lighting Urban road lighting accounts for 30% of the total lighting power consumption, reaching 10% of the national total power consumption. Based on the energy-saving characteristics and intelligent control technology of LED itself, the energy-saving potential of urban road lighting is huge; at the same time, the power line carrier communication based on the power grid (Power Line Communication: PLC) technology also provides an optional technical solution for the communication of smart light poles.
PLC is a communication method that uses power lines to transmit data, and can be divided into narrow-band, mid-band and broadband technologies according to frequency bands. Narrowband power communication technology is the earliest PLC technology used in power distribution networks. There are a series of international standards, such as G3-PLC, PRIME, IEEE 1901.2, etc. The carrier frequency band is mainly distributed in 3-500 kHz, which can be used for broadband access, equipment and motor control, data acquisition, lighting, remote meter reading, etc. The mid-band PLC technology is based on the mid-band technology specified by the State Grid Corporation of China HPLC, and is widely used in the field of domestic electricity consumption information collection.
As the main force in the construction and operation of information and communication infrastructure, China Tower requires that the distribution density of 5G base stations is much higher than that of 4G base stations with the advent of the 5G era. China Tower has an urgent need to reduce site resources and construction costs. In order to alleviate the pressure of site scarcity and investment cost faced by operators in the 5G network construction, China Tower has cooperated with Huawei, ZTE, Huati Technology, Guangdong Urban and Rural Planning and Design Institute, Guangdong Electric Power Design and Research Institute, Tecnon Smart Display and other planning projects. 30 enterprises and institutions in the smart light pole industry chain, including design, tower manufacturers, communication technology, LED lights/screens, security technology, and application platforms, led the establishment of the “Guangdong Smart Pole Industry Alliance” in Guangdong to promote and improve industrial development. ecology. In terms of standard formulation, the “Technical Specifications for Smart Light Pole” edited by Guangdong Iron Tower was reviewed by an expert committee organized by the Guangdong Provincial Department of Housing and Urban-Rural Development and approved as a local standard in Guangdong Province. In terms of specific projects, China Tower is currently in the stage of exploring and reserving resources for the related business of smart light poles. It mainly adopts the EPC or “rent-to-build” model and has carried out 40-50 projects in China in the form of general contracting. Shanghai, Beijing, Guangzhou, Yangjiang, Yunfu, Shantou, Qingyuan, Huizhou, Shaoguan, Yulin, Qingdao, Shaoxing, Jiaxing, Huzhou, Jinhua, Haidong, Hangzhou, Xiong’an, Hohhot, Zunyi, Lijiang, Tianjin, Henan, Nanjing, China Tower branches in Hainan, Qingpu, Quanzhou and other places are all involved in the construction of smart light pole projects.

Huawei has built its own smart city business system, and leveraged its own advantages to deploy smart city business to many cities in China, including first- and second-tier developed cities and third- and fourth-tier cities, and successfully implemented some smart city cases.
In September 2019, during the HUAWEI Connect conference, Huawei first demonstrated Huawei’s HiCity smart city overall solution on its smart city platform, covering top-level urban planning, reshaping urban information infrastructure, and sustainable development and operation. The “1+1+N” solution architecture of the company has been intensively displayed. Huawei’s HiCity smart city solution is built on Huawei’s fertile digital platform.
It can optimize and integrate a variety of new ICT technologies and data, realize business process integration, business data sharing, and information flow transmission, and reduce the use of new technologies. Threshold and integration difficulty. These include smart light pole solutions integrated with Huawei AR/WIFI/IPC, smart road analysis, and smart indoor navigation.
The strategies of ZTE and Huawei are basically the same, and they are also to provide integrated systems and cooperate with lighting manufacturers to deploy the smart light pole industry. In 2016, ZTE proposed the Blue Pillar solution. Blue Pillar consists of smart charging piles, 4GiMacro new concept base station, smart control box and smart street lights. In early 2016, ZTE successfully built the first Blue Pillar model site in Shenzhen Industrial Park and started operation.
After that, ZTE not only established smart light pole pilot projects in Shaanxi, Jiangsu and other regions, but also cooperated with local governments and iron tower companies to build smart light poles for countries or cities such as Romania and Medellin, the second largest city in Colombia.
The purpose of Alibaba and Tencent’s entry into smart light poles is to create gridded neural nodes through smart light poles, create a perception center, and realize the closed loop of the cloud and the closed loop of the edge.
In the scenario solutions of Alibaba and Tencent in Alibaba Cloud and Tencent Cloud, smart lighting is one of the core smart scenario applications. In 2019, Tencent Cloud Computing, Sichuan Huati, Beijing Donghua Co-Creation, and Tencent Industrial Fund won the bid for the Chengdu Huancheng Ecological Zone Ecological Restoration Comprehensive Project (South Area) and Smart Greenway Society (East and West Area) as the joint winning bidder.

After sorting out recent smart light pole bidding projects, it was found that state-owned investment companies, iron tower branches, power companies and relevant government departments are the main procurement entities.
Taking Chengdu City Investment as an example, with the strong support of Chengdu City Investment Group, City Investment Construction Group seized the opportunity of 5G development, took advantage of the wave of smart city construction, and planned to use light poles as a carrier and marketization as a means to develop smart lights. Pole construction and operation, to create an integrated development model of “investment, construction, management, and operation” for urban lighting facilities, to effectively revitalize government assets, and to promote municipal state-owned enterprises to become bigger, better and stronger. In this context, Chengtou Construction Group successfully completed the industrial and commercial registration of a professional company, Chengdu Chengtou Smart City Technology Co., Ltd. (hereinafter referred to as “Chengdu Smart City Company”) in October 2019, and was highly recognized by the leaders of the Municipal Party Committee. Chengtou Smart City Co., Ltd. is actively carrying out the exploration of the business model of the “multi-pole integration” of the first ring road and the pilot demonstration project of 5G base station installation and 5G scenario application of smart light poles. The Operation Reform Pilot Implementation Plan requires that, under the circumstance of tight time and heavy tasks, on October 31, 2019, the “Chengdu Central City Urban Road and Public Landscape Lighting Facilities Entrusted Maintenance Service Intention Agreement” was signed with the Municipal Urban Management Committee, and Formed a work plan with Chengdu Investment Group on the handover of urban lighting facilities and equipment on the Third Ring Road. The effective progress of the above work means that the handover of about 140,000 urban lighting facilities and ancillary facilities within the Chengdu Ring Expressway has officially started. Gradually cover the whole area of Chengdu.
The project construction area extends from closed spaces such as parks and scenic spots to open areas such as the main streets of the city. The owner of the enclosed space and the main body of operation and maintenance in the later stage are relatively unified and easy to coordinate, so they are the main partners for the demonstration and promotion of smart light poles in the early stage.
However, with the development of Internet and Internet of Things technology, as well as the application of cloud technology, big data and other technologies, the trend of adapting to the new urban management model through the adjustment of urban management system and organization has become increasingly clear. Guizhou, Shandong, Chongqing, Fujian, Guangdong The establishment of big data administrations in Zhejiang, Jilin, Guangxi and other provinces is a manifestation of this trend. Only by breaking through the data barriers of various departments at the government level can we truly promote the application of smart city applications represented by smart light poles at the city level or even wider areas.
Different purchasers have different qualification requirements for winning bidders. The qualifications that appear more frequently are municipal engineering construction general contracting qualifications, communication engineering construction general contracting qualifications, mechanical and electrical engineering construction general contracting qualifications, electronic and intelligent engineering professional contracting qualifications, urban And road lighting engineering professional contracting qualifications, and the level of the corresponding qualifications required is generally determined according to the size of the project.
According to the data of the Ministry of Housing and Urban-Rural Development of China, there are not a few companies with the above qualifications. There are 14,917 companies with two qualifications, 3,791 with three qualifications, 598 with four qualifications, and 55 with five qualifications. At present, the construction enterprises of smart light pole projects mainly include Shanghai Sansi, Huati Technology, Unilumin Technology, Longteng Lighting, New Space, Liangye Environment, Wanrun Technology, Sichuan Energy Investment, Taihua Wisdom and Haina Tiancheng, etc. Different levels of relevant qualifications, such as Longteng Lighting has the first-level professional contracting of urban and road lighting engineering, the first-level professional contracting of electronic and intelligent engineering, and the special-level qualification of lighting engineering design. Enterprises that do not have relevant qualifications generally join other qualified enterprises to jointly bid and declare.
Planning and Design
The Bureau of Planning is currently generally called the Bureau of Planning and Natural Resources. As a measure of the state to streamline institutions, it is responsible for planning and natural resources. Its responsibilities include establishing a spatial planning system and supervising its implementation, organizing the preparation of detailed urban planning and urban design, etc. As an auxiliary unit of urban construction, planning and other functional departments, urban planning and design institutes are a small part of the nature of public institutions, and most of them are enterprises. Taking Beijing as an example, the Beijing Institute of Urban Planning and Design is a public institution affiliated to the Municipal Planning and Land Commission.
It is entrusted by the Municipal Planning and Land Commission to be responsible for the organization and demonstration of the city’s urban and rural planning, and to undertake relevant planning tasks assigned by the municipal government; In addition, there are also corporate planning and design institutes such as Beijing Tsinghua Tongheng, Beijing Municipal Engineering Design and Research Institute, and Beijing Urban Construction Design and Development Group.
The design of smart light poles needs to integrate the design requirements of street light poles, monitoring poles, communication poles and traffic poles to meet the requirements of installation space, weight, and working environment of the pole-mounted equipment. At the same time, the hardware interface of the pole should be planned in advance, mainly to reserve the interface and installation space for the mounting equipment and supporting facilities, including the reserved hole size, location and process, reserved cable position, threading space, reserved equipment installation space, etc. Traditional lighting pole enterprises such as Yangzhou Gaoyou and Guangdong Zhongshan generally have small production scale (even family workshop production) and weak technical capabilities (pole material, wall thickness, structure and other key technical links rely on experience, no design and simulation capabilities support), etc.
The problem is that it does not have the ability to design the rod itself. The overall performance of LED lighting companies in rod body design is weak accumulation, and companies with strong design capabilities mainly include Shanghai Sansi, Huati Technology and Shanghai Ximei. At present, the design institutes that have the advantages of technology and experience are the design institutes that have started to get involved in smart light poles from the traditional communication design industry, such as the Huaxin Design Institute and the Posts and Telecommunications Design Consulting Institute affiliated to Zhongtong Service.
At present, the existing domestic communication design/consulting units can be roughly divided into several categories: directly under the former Ministry of Posts and Telecommunications, directly under the former General Administration of Telecommunications, and transformed from communication-related enterprises.
- There are two design institutes directly under the Ministry of Posts and Telecommunications—the China Telecom Posts and Telecommunications Consulting and Design Institute located in Zhengzhou, which is now merged by China United Communications Co., Ltd. and renamed China Unicom Group Design Institute; the Beijing Design Institute of the Ministry of Posts and Telecommunications in Beijing ( Now known as China Mobile Communications Group Design Institute Co., Ltd.).
- All the local design institutes directly under the former General Administration of Telecommunications are now unified under the banner of China Communications Service Corporation. There are three well-known provincial design institutes: Zhejiang Huaxin Design Institute, Guangdong Telecom Design Institute and Beijing Netcom Design Institute.
- There are no less than 1,000 design institutes transformed from communication-related enterprises. The main enterprises (units) are: Jiesai Design Institute (seven institutes of the Electronics Department) and Design Institute of China Communications Construction Corporation.

Device hardware analysis
The main components of smart light poles include smart lighting equipment, 4G/5G micro base stations and WIFI receiver transmitters, video surveillance, public broadcasting, various types of sensors, LED information screens, radio frequency identification, emergency calls, charging piles, etc. As a new generation of infrastructure to promote the digital economy and build a new smart city, smart light poles have expanded applications such as WIFI base stations, video surveillance, advertising screen broadcasting, environmental monitoring, emergency calls, and new energy vehicle charging through iterative upgrades.
In recent years, under the national layout of “new infrastructure” and “5G commercial use”, various places have successively released the construction goals of smart light poles, and the large-scale application of smart light poles has become the general trend. However, the landing of smart light poles is still facing inconsistencies in technology, interfaces, and software.
Under the joint promotion of the Guangdong Provincial Department of Housing and Urban-Rural Development and the Provincial Department of Industry and Information Technology, Guangdong Tower, the chairman unit of the alliance, as one of the editor-in-chief units, unites with 16 related units including urban planning, engineering construction and maintenance, scientific research units, and light pole manufacturers. Compilation of “Technical Specifications for Smart Light Pole”.
The specification is the first provincial standard in the field of smart light poles in China, which fills the gap of the lack of unified technical standards for the construction of smart light poles in Guangdong Province. It has been implemented since October 1, 2019. This technical specification is applicable to the construction of street lights and related poles in newly renovated and expanded roads, squares, scenic spots, parks, parking lots and other areas. The “Technical Specifications for Smart Light Pole” clearly states that as a comprehensive smart city infrastructure, smart light poles should pay attention to the following three points to realize the co-construction, sharing and co-governance of information infrastructure; linking various industry applications to establish a wide coverage , A full-featured information perception network; fully consider the integration with the urban landscape; coordinate the entire network of poles, computer rooms, transmission pipelines, power pipelines and operation management platforms.

(2) Application analysis of functional modules
Through the analysis of existing projects, the CSA Standardization Committee summarized LED lighting, video capture, mobile base stations, public WiFi, public broadcasting, environmental monitoring, weather monitoring, monitoring components, RFID, one-key calling, display screen, charging pile, multimedia There are 22 main functional modules such as interaction, traffic signs, traffic lights, traffic flow monitoring, traffic law enforcement, intelligent gateway, road test unit, location service, integrated chassis, and management platform, and the related naming has been standardized.
Through the analysis of the core application modules, the core functions of the smart light pole are as follows:
Based on LED lighting applications
Urban road lighting is an important part of urban public facilities, and with the advancement of urbanization, the number of urban road lighting street lamps is increasing, energy consumption is getting higher and higher, and power supply tends to be tight. In addition, the maintenance of urban lighting and high maintenance costs (manual control, street light inspection, etc.) have caused huge difficulties to urban management. The management department needs more efficient management and energy-saving solutions, so as to promote the scientific management of urban lighting and green energy-saving.
According to a survey of street lamp management offices in different regions and cities of different scales across the country, including Shenzhen, Guangzhou, Beijing, Chongqing, Zhongshan, Changzhou, Nanchang, Chenzhou, Baise, etc., CSA Research learned that the average number of street lamps in municipalities directly under the Central Government in mainland China exceeds 40. The number of street lamps in prefecture-level cities exceeds 150,000, and the number of street lamps in county-level cities exceeds 40,000. According to the estimation of the number of cities at all levels in my country, the total number of street lamps in my country is nearly 60 million, of which the LED penetration rate is less than 30%.
The electricity consumption of street lamps and road lighting in my country accounts for about 9% of the electricity consumption of the whole society, ranking first in lighting electricity consumption in all fields. Among the 811 cities in the country, only about half of the cities have adopted the “wireless three-remote (remote control, remote control, telemetry) intelligent control system”. However, the “three remote” intelligent control system can only remotely control the lights on and off the lighting equipment in units of regions. Most of the domestic urban road lighting systems do not use network monitoring and management, and the on and off control of most urban street lights is still controlled by each transformer (distribution box). This control method lacks flexibility and cannot obtain real-time access to each street light. It is impossible to control and monitor a single lamp according to the actual situation, adjust the brightness of the street lamp, and cannot achieve effective energy saving.
Based on LED lighting, it can meet the needs of pedestrians and vehicles for urban road lighting, through the replacement and popularization of LED light sources, and through an intelligent network management platform, on the premise of ensuring smooth and safe roads, to achieve single-light / networked control. Smart street lighting meets the business needs of street lighting management departments such as green energy saving, real-time monitoring, and automatic inspection, and is still the basis for smart light pole systems for smart city construction.
Supported by the rod
The material of the street light pole body has evolved into the direction of high strength, strong protection and light weight through the stages of wooden poles, cement poles, iron poles, steel poles, and aluminum alloy poles. With the continuous demand for loading various functional modules on smart light poles, new requirements are put forward for the mechanical bearing capacity, power connection capacity and network access capacity of the pole itself.
Light poles can be divided into three categories according to the complexity of the functional modules carried by the poles. One is a dedicated pole for a single scene and equipped with a single type of functional module, such as LED lighting poles, video capture poles, traffic sign poles, and traffic lights. poles, etc.; the second is fusion poles for comprehensive scenes and equipped with 2-5 functional modules, such as LED lighting and video capture fusion poles for main roads, LED lighting and display fusion poles, etc.; the third is for complex scenes, A fully loaded pole with all major functional modules.
The functional configuration of the current pole is mainly determined according to the different needs of each local government. Taking Shanghai and Shenzhen as examples, Shanghai, in accordance with the principle of “one road, one plan, one pole, one plan”, has successively issued the “Implementation Opinions on Carrying out the Work of Overhead Lines Entering the Ground and Joint Pole Renovation” and “Shanghai Road Joint Pole Renovation”. Technical Guidelines” and other policy documents, and plans to compile documents such as “Standards and Procedures for Setting Up Facilities on Rods”. “Shanghai Road Combined Pole Renovation Technical Guidelines” divides combined poles into 6 main types, A~F. Different types of light poles are equipped with different functional modules: Type A poles are mainly equipped with motor vehicle signal lights; poles and arms are reserved. Interface, other facilities can be installed as needed; B-type poles are mainly equipped with video surveillance; poles and booms have reserved interfaces, and other facilities can be equipped as needed; C-type poles are mainly equipped with lane signs; poles and booms are reserved for interfaces, Other facilities can be carried as needed; D-type poles are mainly equipped with large and medium-sized road signs; the pole body and boom arm have reserved interfaces, and other facilities can be carried as needed; E-type poles are mainly equipped with small road signs in road sections, and other facilities can be installed as needed Equipped with; F-type pole road lighting pole, with reserved functions, can be equipped with small facilities and equipment.
Shenzhen has successively issued policy documents such as “Shenzhen New Smart City Construction Overall Plan”, “Shenzhen Multifunctional Smart Pole Construction Development Action Plan (2018-2020)”, “Multifunctional Smart Pole System Design and Engineering Construction Specifications” and other policy documents. Efforts will be made to promote the construction of multi-functional smart poles, as an information infrastructure that can be widely used in smart cities. In the “Code for Design and Engineering Construction of Multifunctional Smart Pole System”, it is recommended that multifunctional smart poles can be divided into several configurations according to function combinations, such as Type I, Type II, and Type III (Type I should support at least two functions, Type II It should support at least 3 to 4 functions, and Class III should support at least 5 or more functions); at the same time, it is recommended to divide two categories of municipal roads and parks according to different application scenarios. Taking the smart pole as an example, an example of application design is given: the main road multi-functional smart pole is mainly equipped with intelligent lighting, video acquisition, mobile communication, environmental monitoring, meteorological monitoring, radio monitoring, traffic detection, one-key calling, information release screen, Multi-media interactive terminals, electric vehicle charging equipment; multi-functional smart poles in residential areas are mainly equipped with intelligent lighting, video collection, mobile communication, traffic detection, one-key calling, information release screens, multimedia interactive terminals, and weather monitoring.
Application scenarios based on video capture
(1) Face recognition
The face recognition system takes face recognition technology as the core. For the entrances and exits of important places, such as government offices, embassies, high-speed railway stations, airports, hotels, etc., through high-definition cameras, the faces in the scene are compared with the blacklist database (such as fugitives, key monitoring personnel) in real time, and the alarm is timely; Realize body recognition , given a person in a video or picture from a certain perspective, find the target person with a specific posture from the video or picture of other unrelated scenes; in order to find that the suspect cannot confirm the identity, through the static face retrieval and portrait database Perform big data analysis to quickly determine the suspect’s identity; in the video of the suspect’s appearance, the face is structured in real time, and colleagues provide a trajectory retrieval function to help find the suspect’s foothold afterwards; Face-to-face customs clearance equipment is set up in important customs clearance places such as customs entrances, and potentially dangerous persons are eliminated through the “integration of human and ID cards”.
Based on face recognition, crowd analysis is performed, and functions such as people counting/density estimation, retention and confusion analysis, trajectory and motion analysis, and cross-line counting are realized.
(2) Traffic law enforcement
The traffic law enforcement system mainly includes five parts: electronic police front-end subsystem, urban traffic monitoring subsystem, left-hand prohibited capture subsystem, illegal parking capture subsystem and intelligent traffic integrated management and control platform. The electronic police front-end subsystem is the electronic police front-end equipment. It adopts an integrated video electronic police front-end, which can increase the functions and performance of the electronic police in the aspects of passing vehicle information recording and off-site punishment, and improve the stability and security. The subsystem can capture pictures, extract passing vehicle information, recognize and record illegal driving behaviors of motor vehicles, such as running red lights, not following the guide lane, driving in the wrong direction, and changing lanes, and provides high-definition video recording at intersections.
The urban traffic monitoring subsystem transmits the front-end image and the control signaling from the center point-to-point through the point-to-point transmission link. Realize urban road environment monitoring for real-time feedback of traffic flow, public security events, and traffic environment.
The No-Left Snapshot Subsystem identifies and records vehicles that illegally turn left at the intersection through real-time monitoring of the intersection lanes and video analysis algorithms.
The illegal parking capture subsystem uses the high-definition automatic tracking ball camera and the rear illegal parking analysis and detection server to determine whether there are motor vehicles illegally parked in the prohibited parking areas on both sides of the road, intersections, etc., and will reflect the complete illegal parking behavior before and after. Photos and videos are saved, and the function of automatic license plate recognition can be realized. The system can not only work in automatic judgment and recording mode, but also switch to manual control and capture when necessary. Through the platform client and command center transmission and control equipment, the front-end dome camera’s PTZ action, capture pictures, video and other functions can be realized. .
The intelligent traffic comprehensive management and control platform realizes unified access management of front-end equipment and central equipment, and collects, transmits, and processes information flow, including pictures, videos, passing data, traffic flow raw data collected by off-site punishment system, and analysis results. It also supports the connection with the outfield information board to realize the release of traffic information. The platform realizes the centralized storage of traffic monitoring resources, has a flexible and efficient storage management mechanism, and adopts a cloud storage system to realize the storage of massive pictures, data and videos. The platform supports access to the video quality diagnosis system, which is used to give alarms to the real-time video collection and transmission of the front-end video, such as blur, jitter, color cast and other conditions. The comprehensive management and control platform adopts an open architecture design. Through the data interface, it can be connected with the monitoring platform and traffic command platform of the existing detachment to realize richer business functions and applications.
(3) Autonomous driving
Self-driving cars combine a variety of sensors to sense their surroundings, such as radar, lidar, sonar, global positioning systems, odometers, and inertial measurement units. Advanced control systems interpret sensory information to identify appropriate navigation paths, obstacles and associated signs. In 2021, Keji Road (East Changshou Road-Chunyuan Road) in Zhonghe Street, Yinzhou District, Zhejiang Province will be constructed and put into use as an assisted autonomous driving road with smart light poles as the carrier. The project adopts 5G-V2X, a cutting-edge technology, which can quickly release information such as traffic lights, pedestrian intrusions, and construction on the roadside with an ultra-short delay as low as 10 nanoseconds, and conduct information exchange in a timely and efficient manner, enabling Vehicle-road coordination is possible.
Application scenarios of atmospheric grid monitoring based on environmental/meteorological sensors
According to the “Environmental Information Network Construction Specification” (HJ460-2009), “Technical Specification for Environmental Protection Application Software Development and Management” (HJ622-2011), “Data Transmission Standard for Online Automatic Monitoring and Monitoring System of Pollution Sources 2122005”, “Environment National standard protocols such as Technical Specifications for Automatic Monitoring Information Transmission and Exchange of Pollution Sources (HJ-T352-2007), based on the data sensing system of environmental monitoring points, establish intelligent Grid online monitoring system data platform.
This application scenario requires real-time collection and transmission of environmental/meteorological monitoring data within the coverage of each monitoring point, real-time monitoring of environmental/meteorological parameters, online data query and report statistics, automatic data early warning, comprehensive information analysis, data collection and ranking feedback, etc.
All monitoring points are classified and displayed according to their administrative areas and functions. The environmental/meteorological parameter levels of monitoring points are distinguished and dynamically displayed by different icon colors. At the same time, the number and geographical location of the points can be marked, which is convenient for users to grasp the information at a glance. The deployment of monitoring sites within the jurisdiction and the current environmental/meteorological status.
The monitoring site can be combined with the installation of video surveillance equipment to intuitively understand the surrounding conditions of the monitoring site through the window view, providing a basis for the public and management departments to supervise and enforce the law, and at the same time to understand the real-time status of the monitoring equipment. When the data is abnormally reminded, the scene situation can be judged by returning the image data (requires manual work). When a force majeure factor occurs, the accident details can also be judged based on the image data.
At the same time, the system provides early warning and daily notification functions. The early warning includes over-standard warning, disconnection warning and abnormal value warning. When the monitoring value exceeds the standard, the data connection is interrupted and abnormal values occur, it will automatically send reminder information to the set contacts to ensure the system normal and stable operation. The atmospheric grid detection system can also provide air quality and meteorological data export functions. Users can export data after setting the time type, site, and time period. The content includes point information, data update time, conventional 6-parameter concentration values, main Pollutants, Air Quality Index AQI.
(3) Industry development trend
From 2015 to 2019, many smart light pole projects were carried out across the country, but most of them were of the nature of pilot demonstration and the project scale was small. With the recent intensive announcement of policies on smart light poles in more than 10 provinces and cities, 2020 will become the first year for large-scale smart light pole projects to be implemented.
At present, traditional street light companies, light poles, display companies and control system companies are the leading forces in promoting the application of smart light poles. “Multiple poles in one” means the transformation of old poles and the construction of new poles. The most direct way is to increase orders for light poles, lamps, control software and hardware, and engineering construction. The added value of smart light poles is high. For these For enterprises, it is also an important entry point to find new profit points. In addition, smart light poles are also the starting point for such companies to cut into smart cities, so companies have laid out in advance.
Among communication and Internet technology companies, Huawei and ZTE focus on the sales of their communication equipment (4G/5G base stations) and the promotion of their communication solutions. Internet companies Tencent and Alibaba focus more on cloud storage and data processing. Currently, smart light poles are in demonstration applications. At this stage, it has not reached the metropolitan level, and it takes a wait-and-see attitude.
Among the basic network service providers, due to the urgent need for the reduction of site resources and construction costs of China Tower, and its abundant funds, it is currently making great efforts in the application and promotion of smart light poles.
Judging from the current market situation, it is still in the early stage of the development of the smart light pole market, which is characterized by: small project scale, unclear profit model, undetermined benefit distribution, numerous participating companies, and a competitive landscape that has not yet been formed. From the perspective of market trends, first of all, the value of the smart light pole industry chain will continue to move from the hardware manufacturing link to the downstream system operation link, because the hardware cost of hardware equipment providers is gradually reduced and the replaceability is enhanced; the current market Many system solutions do not start from the fundamental needs of the market, emphasizing compatibility and unification in order to integrate data. Operators will be the core link of the smart light pole system, and their status in the industry chain will gradually increase. Secondly, the future large-scale application projects and the current pilot projects will be quite different from the business model to the operational requirements. The current pilot project is mainly based on the government purchase model. The large-scale project may adopt a variety of business models, and the scale of the project Operating enterprises must open up various intelligent applications of smart light poles to meet the real needs of service buyers, and have sustainable operation teams and operational capabilities.
