Abstract

The invention discloses a control method for a multi-channel video signal automatic switching control system, which includes a wireless video transmitting module, several video receiving modules, several signal extraction modules, several signal processing modules, a control unit, an execution unit and a video display; the video transmitting module The module transmits a wireless video signal, the video receiving module receives the wireless video signal, and transmits the video signal to the signal extraction module, the signal extraction module outputs a voltage signal, and the signal processing module processes the voltage signal, And transmit the processed voltage signal to the control unit, the control unit judges the signal and outputs a control signal, and transmits the control signal to the execution unit, and the execution unit transmits the control signal to the video display It is controlled to make the video display display a clear video. By adopting the above solution, the signal can be kept uninterrupted, and there will be no problems such as unclear video signals due to poor wireless electromagnetic wave signals.

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...
