Description
technical field [0001] The invention relates to coal mine underground mining technology, in particular to a novel coal mine underground video camera signal transmission monitoring system. Background technique [0002] In the traditional coal mine underground video camera signal transmission monitoring system, the video monitoring system must use optical fiber to achieve long-distance transmission signal transmission, and the video signal needs to be transmitted to the video hard disk drive must be transmitted to the video optical transceiver through the camera telecommunications coaxial cable, and the optical transceiver Convert the signal into an optical signal and send it to the video optical transceiver. The video optical transceiver converts the video signal into an electrical signal and then connects it to the video hard disk drive. The hard disk drive is connected to the underground network switch through the network port, and the signal is transmitted to the ground vid...
