Embodiment Construction

[0024] figure 1 Among them, the synchronous and asynchronous integrated LED large screen control system includes a control computer, a main control board and an LED drive circuit. The computer is connected to the main control board through a DVI interface or an asynchronous communication port, and the main control board is connected to the LED drive circuit through Ethernet. . A scanning board is also arranged between the main control board and the LED driving circuit, the main control board is connected to the scanning board through the Ethernet, and the scanning board is also connected to the LED control circuit.

[0025] When the main control is used synchronously, use the DVI interface to connect with the computer. When controlling asynchronous applications, use RS232, RS485, 10M / 100M Ethernet or USB to connect to the computer.

[0026] If you don't need power detection, LED fault detection function, door magnetic switch, temperature alarm, high temperature reduction of ...

Abstract

The invention relates to an LED large screen control system featuring integration of synchronous and asynchronous control, which can have the compatibility of synchronous and asynchronous application, facilitates engineering construction and maintenance and has high reliability, expandability and upgradability. The technical proposal of the invention is that the invention is characterized by comprising a control computer, a master control panel and an LED drive circuit, wherein, the computer is connected with the master control panel by a DVI interface or an asynchronous communication port, the master control panel is connected with the LED drive circuit by the Ethernet.

Description

technical field [0001] The invention belongs to the field of LED large screen control systems, in particular to a synchronous and asynchronous integrated LED large screen control system that is compatible with synchronous and asynchronous applications, facilitates engineering construction and maintenance, and has high reliability, scalability and upgradeability. Background technique [0002] At present, the LED screen control system at home and abroad is divided into two types: synchronous control system and asynchronous control system. The synchronous control system is a special monitor, which puts the computer, or TV programs, radio and other programs on the monitor or display. The synchronous LED control system is different from ordinary monitors. The asynchronous system sends the content to be displayed to the control system through the computer through the Ethernet, serial port, USB interface and other interfaces, and controls the sub-window display of the LED large scr...
