The product is widely used in stage display, commercial application, shop decoration and other directions through innovative design. The appearance of interactive floor floors provides a more novel way of expression for various performances and creative designs. It is a display device for the current Helpful supplements. In the increasingly prominent situation of product homogeneity in the LED display market, the emergence of interactive floor provides a reference for China’s LED innovative applications. Interactive floor screens have considerable market prospects.
1, LED interactive floor screen history
Before the advent of LED floor screen, similar products on the market are also used in commercial decoration. Glowing floors can display patterns on the floors. Such floors usually rely on the built-in SCM to control the display of simple patterns or can be controlled by connecting to the computer so that the entire stage can display changing effects. However, these patterns or effects are preset. In a single-chip computer or computer, it is simply a control output based on the program, which does not generate any interaction with the people on the stage. With the development of touch technology in recent years, there have been light-emitting floors that can interact with people, and its novel and interesting experience modes are favored by the market. The realization principle of the interactive floor screen is to set a pressure sensor, a capacitive sensor or an infrared sensor on the floor floor. When the person interacts with the floor floor screen, these sensors sense the position of the person and feed back the trigger information to the main controller, and then The main controller logic outputs the corresponding display effect after judging.

The common interactive floor floors control methods include: off-line control mode, Ethernet on-line control mode, and wireless distributed control mode. Corresponding floor screen products are produced for different engineering applications and the supporting effect production software is designed to use the software. “Seekway Dance Player”, the user can control the floor screen to enter the interactive mode of different patterns (can be used separately or at the same time to achieve sensor patterns and induction sound function) or as a screen to play full-color images. Multiple sets of gorgeous built-in effects can be generated with one click, and different format effects can be intercepted or imported; powerful text editing functions can be used to edit text effects as needed; brightness and speed can be adjusted in real time; and brightness and speed can be flexibly adjusted according to the application; You can also set or modify the project parameters and route carefully through the installation settings, which is simple and quick.
3, LED interactive floor screen offline control and Ethernet connection control
The offline floor control system is composed of multiple subsystems, each of which includes a sensor detection unit, an LED display unit, a detection processing unit, and a display control unit uniformly distributed on the circuit board. The sensor detection unit is connected with the input end of the detection processing unit, the LED display unit is connected with the output end of the display control unit [4], and a data processor independent of the subsystem is also provided with its output interface and the display control unit of the subsystem. The input interface is connected, and its input interface is connected with the output interface of the detection processing unit. In an actual product, each subsystem is a floor screen module. When connecting, the subsystems are connected in series through a communication interface and a data processor.
4, LED interactive floor screen offline control
When using the offline control mode, the offline controller functions as a data processor. On the one hand, it needs to receive the information transmitted from all the sensor detection units, and after the data fusion processing, the position of the triggered floor screen can be known, and then read. Take the data files stored in mobile storage devices such as CF cards and SD cards to achieve 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.
5, LED interactive floor screen Ethernet online control
When using the Ethernet connection control method, the calculator functions as a data processor. Since the computer has a more powerful data processing capability, this control method can modify the display effect at any time and can realize unified monitoring of a large stage in real time. Modules can be extended in a cascaded manner, which has great advantages in large-scale interactive floor screen engineering applications.
6, LED interactive floor screen wireless distribution control
Based on the wireless distributed control interactive floor screen system design method, compared to the previous system design, the control method operates in a wireless manner, eliminating the need for on-site wiring. At the same time, distributed control is used to distribute the work of the data processing part. In each floor floor control processor, the data processing part is cooperatively completed by these processors. Therefore, the main controller part does not need powerful data processing capability. In a large application, it does not need to use a computer as a data processing center. This control method Can greatly reduce system design costs.
7. The working process and principle of the wireless distributed control floor screen system are described as follows
After the touch point of the floor screen is triggered, the sub-controller connected to it will wirelessly transmit the position ID information of the trigger point to the main control; after the main control receives the position information, the position information is synchronized to the broadcast position by the main control device. All sub-controls; sub-control will transmit this information to the processor inside each floor screen, so each floor screen module will automatically calculate its own position distance from the trigger point, and then determine the display effect it should display; The system uses a special synchronization frame to realize that the system has a unified time reference. Therefore, each floor screen module can accurately calculate the time for which it should display the corresponding effect, and then the entire trigger effect can be seamlessly connected and perfectly displayed.

(1) Off-line control mode. Since the main controller has limited data processing capabilities, it is mainly used for desktop interactive sensing and is suitable for relatively small applications such as bar tables and KTV room countertops.
(2) Ethernet on-line control method can be applied to occasions such as large-scale stage control. Since the computer is used as a data processing center, this control method can be easily modified to display the effect at any time and can be unified on a large-scale stage in real time. Monitoring.
(3) Wireless distributed control mode, which is different from the above two wired data transmission modes. This method realizes the key data transmission through wireless. In practical engineering applications, it not only improves the layout efficiency at the site, but also reduces the labor Cost and wire costs, which have a clear advantage in large-scale applications.
At the same time, in terms of data processing, different from the above two centralized processing methods, the wireless distributed control method spreads the work of the data processing part to the control processors of each floor screen, and the co-processing of these processors completes the display of the effect. Therefore, the main controller does not need powerful data processing capability, and it does not need to use a computer as a data processing center when it is applied to a large stage, so that the overall system application cost can be further reduced.
