Abstract

The display panel and communication switch of the invention is connected to the MPU; the memory is connected to the MPU; the video input is connected to the signal checking; the signal checking is connected to the MPU; the video input is connected to the high speed image collection; the high speed image collection is connected to the MPU. The video input is connected to the electronic switch, the electronic switch is connected to the video output; the electronic switch is connected to the MPU; UART interface is connected to the MPU; the network card port is connected to the MPU. The invention can automatically detects the station caption image of the satellite TV station; when finding an illegal signal to access, it can automatically cutoff the downlink signals to block the transmission of illegal signal to the cable TV users, and meanwhile the monitor sends out sound and light warning signals.

Description

technical field [0001] The invention relates to a device for monitoring and controlling satellite receivers, in particular to a monitor for satellite receivers. Background technique [0002] The security of cable TV network has always been a very important issue. Once the satellite signal is invaded by illegal signal, it will have serious consequences. At present, there is no mature method for the safety protection of satellite receivers. Contents of the invention [0003] The purpose of the present invention is to provide a satellite receiver monitor for the current status quo. It uses computer artificial intelligence, image recognition and other high-tech means to automatically monitor the image of the station logo in real time, and if it finds that the station logo is abnormal (the station logo is lost or the content of the station logo changes), it will be determined that there is an illegal signal intrusion, and the monitor will automatically shut down the channel. ...
