Summary:The utility model discloses a multichannel video signal automatic switch -over control system, including wireless video emission module, a plurality of video receiving module, a plurality of signal extraction module, a plurality of signal processing module, the control unit, execution unit and visual display unit, video emission module launches wireless video signal, video receiving module receives wireless video signal to transmit video signal to the signal extraction module, signal extraction module output voltage, signal processing module is right voltage signal handles to voltage signal after will handling transmits and gives the control unit, the control unit carries out decision output control signal to the signal to give control signal transmission execution unit, it is right that execution unit passes through control signal transmission visual display unit controls, makes visual display unit shows clear video. Adopt above -mentioned scheme, but the inhibit signal is continuously incessant, can produce the blurring scheduling problem of video signal because of radio magnetic wave signal is poor.
