The principle and design plan of full-color LED interactive floor tile screen

The emergence of interactive LED floor tile screens provides a more novel performance technique for various stage performance creative designs, and is a useful supplement to current LED display equipment. Under the situation that the problem of product homogeneity in the LED display market has become increasingly prominent, the emergence of LED interactive floor tile screens provides a reference for innovative LED applications, and interactive floor tile screens have considerable market prospects.

The development history of LED interactive floor tile screens

Before the emergence of interactive floor tile screens, similar products on the market luminous floor tiles were also used in commercial decoration and other aspects.

Luminous floor tiles can display patterns on the floor tiles. Such luminous floor tiles generally rely on the built-in single-chip microcomputer to control and display simple patterns or can be controlled by connecting a computer so that the entire stage can display changing effects, but these patterns or effects are present in In the single-chip microcomputer or computer, the control output is purely based on the program, and there is no interaction with the people on the stage.

With the development of touch technology in recent years, luminous floor tiles that can interact with people have appeared, and their novel and interesting experience methods are favored by the market.

The realization principle of the interactive floor tile screen is to set a pressure sensor or capacitive sensor or infrared sensor on the floor tile. When a person interacts with the floor tile screen, these sensors sense the position of the person and feed back its trigger information to the main controller, and then The main controller outputs the corresponding display effect after logical judgment.

LED interactive floor tile screen control methods

Common interactive floor tile control methods include offline control mode, Ethernet online control mode, and wireless distributed control mode.

Corresponding floor tile screen products have been produced and designed for different engineering applications. Effect production software, using the software, the user can control the floor tile screen to enter the interactive mode of different patterns (respectively or simultaneously realize the function of sensing patterns and sensing sound effects) or as a screen to play full-color images.

You can generate multiple sets of gorgeous built-in effects with–keys, and you can also intercept or import effects in different formats; with powerful text editing functions, you can edit text effects as needed; adjust brightness and speed in real time, and adjust brightness and speed flexibly according to the application; Users can also carefully set or modify engineering parameters and wiring through installation settings, which is simple and fast.

LED interactive floor tile screen offline control and Ethernet online control mode

Offline control and Ethernet online control mode The interactive floor tile screen control system is composed of multiple subsystems, and each subsystem includes sensors evenly distributed on the circuit board. The detection unit, the LED display unit, the detection processing unit and the display control unit.

The sensor detection unit is connected to the input end of the detection processing unit, the LED display unit is connected to the output end of the display control unit, and a data processor independent of the subsystem is also provided The output interface is connected with the input interface of the display control unit of the subsystem, and the input interface is connected with the output interface of the detection processing unit. In the actual product, each subsystem is a floor tile screen module.

When connecting, the subsystems are connected in series through the communication interface, and the data processor.

Offline control mode of LED interactive floor tile screen

When the offline control mode of the LED interactive floor tile screen is adopted, the offline controller functions as a data processor.

On the one hand, it needs to receive the information transmitted back by all the sensor detection units, which can be obtained after data fusion processing. Know the position of the floor tile screen that is triggered, and then read the data files stored in the CF card, SD card and other mobile storage devices to realize the corresponding effect display.

The design of the off-line controller is composed of a single-chip computer with strong data processing capability and its peripheral circuits.

LED interactive floor tile screen Ethernet online control mode

When the Ethernet online control mode is adopted, the calculator functions as a data processor. Because the computer has more powerful data processing capabilities, this control mode can modify the display effect at any time and can real-time Realize unified monitoring of large-scale stages from the ground. Modules can be expanded in a cascading manner, which has huge advantages in large-scale interactive floor tiles and screen engineering applications.

LED interactive floor tile screen wireless distributed control method

The LED interactive floor tile screen wireless distributed control method is based on the wireless distributed control of the interactive floor tile screen system design method.

Compared with the previous system design, the control method works wirelessly, eliminating the trouble of field wiring and adopting distributed Control, distributing the work of the data processing part to the control processors of each floor tile screen.

The data processing part is completed by these processors. Therefore, the main controller part does not need strong data processing capabilities, and it is not necessary to use it in large-scale applications. As the computer is used as a data processing center, this control method can greatly reduce the cost of system design.

Summary of LED interactive floor tile screen

  • Offline control mode. Due to the limited data processing capacity of the main controller, it is mainly used for desktop interactive induction, suitable for relatively small applications such as bar counters and KTV room countertops.
  • The Ethernet online control method can be applied to large-scale stage control and other occasions. Because the computer is used as the data processing center, this control method can easily modify the display effect at any time and can realize the unified control of the large-scale stage in real time. –The monitoring.
  • The wireless distributed control method is different from the above two wired data transmission methods. This method realizes key data transmission through wireless. In actual engineering applications, it not only improves the efficiency of on-site layout, but also reduces labor Cost and wire cost, which have more obvious advantages in large-scale applications.

At the same time, in terms of data processing, it is different from the above two centralized processing methods. The wireless distributed control method distributes the work of the data processing part to the control processors of each floor tile screen, and these processors cooperate to complete the display of the effect.

Therefore, the main controller does not need powerful data processing capabilities, and it is not necessary to use a computer as a data processing center in large-scale stage applications, so that the application cost of the overall system can be further reduced.
