At this time, the relay wireless transmission modem in the relay module within the wireless transmission range receives and demodulates the wireless signal. The relay modules can be installed on high towers, the number of the high towers can be selected according to the required work range of image transmission or other data transmission, and reasonable layout is carried out, so that the relay modules exist in the wireless image transmission or other data transmission ranges of any work positions, and the application range of the image transmission and other data transmission functions is further ensured. After the relay module receives data, if information processing is needed, the repair device in the relay module can be used for correction and repair, and then the relay cable transmission modem is used for modulating signals and transmitting the signals to the other end of the cable network through a cable broadband. And a cable transmission modem positioned at the other end of the cable network receives and demodulates signals, and finally, a video decoder in the image presentation module is used for carrying out video decoding and presenting real-time images on display equipment. If the data processing is not needed, the data is directly transmitted through the wired transmission module. The wired transmission module reduces the influence of environmental factors on data transmission, has larger bandwidth and provides guarantee for the efficiency and reliability of data transmission. The system improves the image transmission quality by combining wireless and wired modes, ensures the stability of the system and provides reliable reference for subsequent work.
