Abstract

The invention discloses a system and method for controlling automatic switch of multi-channel video signals. The system comprises a wireless video transmitting module, a plurality of video receiving modules, a plurality of signal extracting modules, a plurality of signal processing modules, a control unit, an execution unit and a video display; the wireless video transmitting module is used for transmitting wireless video signals; the video receiving modules are used for receiving the wireless video signals and transmitting the video signals into the signal extracting modules; the signal extracting modules are used for outputting voltage signals; the signal processing modules are used for processing the voltage signals and transmitting the processed voltage signals to the control unit; the control unit is used for judging the signals, outputting control signals and transmitting the control signals to the execution unit; and the execution unit is used for controlling the video display through transmission of the control signals, so that the video display displays a clear video. By adopting the scheme, continuous signals can be kept; and the problems of unclear video signals and the like due to poor wireless electromagnetic wave signals can be solved.

Description

technical field [0001] The present invention relates to the technical field of video automatic switching control, in particular to a control method for a multi-channel video signal automatic switching control system. Background technique [0002] Video surveillance is an important part of coal mine safety management. In recent years, video surveillance has made great progress in coal mines. With the advancement of information technology in coal mines, video surveillance technology has been used as an important means of coal mine safety management in transportation, hydrology, etc. , production and other aspects. [0003] Coal mining production is an important link in coal mine production. Coal mining safety is related to the overall situation of the coal mine, and the supervision of coal mining is particularly important. At present, the supervision methods are relatively simple, and ground dispatching is still mostly done by telephone. The environment of the coal mining fac...
