Video wall control system

Abstract

The invention discloses a splicing display device control system, which includes a controller unit, a first power network bridging module, and a second power network bridging module respectively connected to the display units of the splicing display device; the controller unit is bridged through the first power network The module is connected to the power line, and the display unit is connected to the power line through the second power network bridge module; the controller unit outputs a control signal to the first power network bridge module according to the control operation, and the first power network bridge module loads the control signal to the power line; the second The second power network bridge module obtains control signals from the power line, and sends the control signals to corresponding display units. In the present invention, the display unit is connected to the power line through the first power network bridge module, and then connected to the power network, which saves a lot of wires, and there are links for mutual communication between them, and implements intelligent lighting according to the background light mode determined by the controller unit. Dimming.

Description

technical field [0001] The present invention relates to the technical field of splicing display, in particular to a control system of a splicing display device. Background technique [0002] The traditional splicing display device control system is based on LAN and RS485 industrial network. Each display unit of the splicing display device has a serial interface or network cable interface and at least one video input port such as DVI interface. The serial interface communicates and controls the display unit, and the processor connects to the video input port through the video cable to transmit the content of the image signal generated by the corresponding display unit. [0003] Peripheral devices such as dimming lights are far away from the control computer, and the control computer generally needs to convert serial port signals into RS485 differential signals for transmission to peripheral devices. Therefore, in addition to power lines for connection, this splicing display ...
