Principle and design scheme of full-color LED human body interactive floor tile screen (一)

 LED floor tile screen this product is widely used in stage display, commercial application, store decoration and other directions through innovative design. The emergence of interactive LED floor tile screen provides a more novel expression method for various performance creative design, which is a beneficial supplement to the current display equipment.

With the increasingly prominent problem of product homogeneity in the LED display market, the emergence of interactive floor tile screen provides a reference idea for the innovative application of LED in China. The interactive floor tile screen has a good market prospect.

1. Development history of LED interactive floor tile screen

Before the emergence of interactive floor​ tile screen, similar products in the market, luminous floor tiles, were also used in commercial decoration.

The luminous floor tile can display patterns on the floor tile. This kind of luminous floor tile generally depends on the built-in single-chip microcomputer to control and display simple patterns, or can be controlled by connecting the computer, so that the whole stage can display changing effects. However, these patterns or effects are preset in the single-chip microcomputer or computer, which is only based on the control output of the program and will not have any interaction with the people on the stage.

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

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

2. Led interactive tile screen control mode

Common interactive floor tile control modes include offline control mode, Ethernet online control mode and wireless distributed control mode. Corresponding floor tile screen products are produced for different engineering applications, and supporting effect production software is designed. Using the software seekway dance player, The user can control the floor tile screen to enter the interactive mode of different patterns (the functions of sensing patterns and sensing sound effects can be realized respectively or at the same time) or play full-color images as a screen.

Multiple sets of gorgeous built-in effects can be generated with one click, and effects in different formats can also be intercepted or imported; It has powerful text editing function and can edit text effects as needed; Adjust the brightness and speed in real time, and flexibly adjust the brightness and speed according to the application; Users can also carefully set or modify engineering parameters and wiring through installation settings, which is simple and fast.

3. Led interactive tile screen offline control and Ethernet online control mode

The interactive tile screen control system of off-line control and Ethernet on-line control mode is composed of multiple subsystems. Each subsystem includes sensor detection unit, LED display unit, detection processing unit and display control unit evenly distributed on the circuit board. The sensor detection unit is connected with the input end of the detection processing unit, and the LED display unit is connected with the output end of the display control unit [4], It is also equipped with a data processor independent of the subsystem, its output interface is connected with the input interface of the display control unit of the subsystem, and its input interface is connected with the output interface of the detection and processing unit.

In the actual product, each subsystem is a tile screen module. When connecting, the subsystems are connected in series through the communication interface and the data processor.
