For the problems of data disorder and misoperation caused by interference during the telemetry system remote data transmission, a kind of LVDS communication system with high reliability has been put forward. To achieve the communication between telemetry data storage system and aircraft ground equipment, it takes FPGA as the control core and use LVDS high-speed data transmission technology in the system. In order to ensure the accuracy and reliability of the data link and command control link, a set of complete communication protocol has been designed. Experiments show that, the communication system performance is stable and reliable in the terms of data and command transmission. the system has been applied to a remote data communication system.
