A LED lighting screen control system and its implementation method

Abstract

The invention discloses an LED lighting screen control system, which includes an Ethernet communication module, the Ethernet communication module is respectively connected with a client and a data receiving module, and the data receiving module is connected with a parameter setting module and a data cache output module; the data receiving module is The control core and the data cache output module are cache cores. The invention also discloses a realization method of the LED lighting screen control system. The present invention uses MCU chip STM32F407ZET6 and FPGA to realize dual-local IP eight-port data output based on ARTNET protocol, Ethernet communication protocol, and DMX512 protocol, which has a high improvement in performance, facilitates the operation of users, and realizes real-time and efficient data processing. Transmission and processing are very promising technologies.

Description

technical field [0001] The invention relates to LED light screen technology, in particular to an LED light screen control system and its implementation method. Background technique [0002] With the development of science and technology, people's demand for products is also constantly improving. In the field of lighting, people are no longer satisfied with the realization of basic lighting functions, and have higher pursuits for the use of lighting scenes, rendering effects, and value costs. The rapid development of LED lighting technology has laid a good foundation for the use of LED lighting screens. Today, LED lighting screens have very important uses in landscape lighting, commercial advertising, stage lighting performances and other fields. [0003] The control technology of the existing LED lighting screens on the market is basically a low-performance four-port data output control board. This control method uses a low-performance MCU as the control core, and the data ...

AI Technical Summary

Problems solved by technology

This control method uses a low-performance MCU as the control core, and the data receiving, processing, and cache output processes are all carried out in the MCU, which causes serious operating pressure and storage pressure on the MCU, resulting in low display frame numbers and data interaction. Low capacity, small amount of data cache

[0004] The use of manual buttons, display screens or directly fixed parameters during parameter setting causes inconvenience to users in terms of use and functional experience, and parameter setting is also more troublesome, which also leads to cumbersome device matching process

When used on large-scale projects, in order to improve the effect, it is necessary to increase the number of control boards and match switches at the same time, resulting in waste of resources and high costs.
