Redundancy device of large-screen image processor based on display detection and control method

Abstract

The invention relates to a redundancy device of a large-screen image processor based on display detection and a control method. The system comprises a display wall, an image processor, a control computer, a signal distributor, a network switch and a computer for providing a signal source, client operation software for large-screen display, a control image processor and a large-screen display unitare installed on the control computer, and one control computer synchronously controls two hardware type image processors with identical configurations. The control computer is respectively connectedwith the large screen and the network switch, the network switch is respectively connected with the two hardware type image processors with the same configuration, the computer is connected with the signal distributor, and the signal distributor is connected with the image processor. According to the invention, the fault which cannot be normally displayed and occurs in the image processor can be accurately judged. The display recovery speed is high; And the original display scene can be recovered, and real display redundancy is realized.

Description

technical field [0001] The invention relates to a large-screen display system, in particular to a redundant device and control method of a large-screen image processor based on display detection. Background technique [0002] At present, large-screen display technology has been widely used in government, military, energy, transportation, public safety, production management and other fields. Especially since entering the era of big data, data visualization has developed rapidly. Large-screen display systems are used as terminals for information processing. Display equipment, with a large display area, ultra-high resolution of the entire screen, a large amount of data displayed at the same time, and real-time information updates, provides a system display platform for efficiently displaying graphic data, which is indispensable. Due to the real-time data display and information processing, the large-screen display system can meet the 7x24 hours of continuous work, and some imp...

Problems solved by technology

This automatic switching technology is based on the method of network detection. It detects the network status of the image processor through software to infer whether the processing is working normally. Therefore, it is necessary for this processor to have an operating system. It cannot be guaranteed that each output board device installed on this computer platform is a normal output display. Therefore, even when the image processor network is working normally, the output of the image processor may be in an abnormal working state. There is no output, resulting in a black screen. Unacceptable on many important occasions
