Analysis and research on data transmission interference of telemetry monitoring equipment of navigation beacon under electromagnetic noise source environment

In the process of data transmission,the telemetry information monitoring equipment of navigational AIDS will be interfered by electromagnetic noise sources,which leads to the derivative problems of telemetry interference of navigational AIDS,that is,the regional,periodic and multiple time-out alarm problems of telemetry data of navigational AIDS in navigational AIDS information monitoring system.In order to solve the interference caused by environmental noise sources and further improve the anti-jamming and interference identification ability of telemetry information monitoring equipment of navigational markers in the jurisdiction area,this paper aims to analyze and study the electromagnetic interference problems of telemetry terminal module of navigational markers based on the actual daily management and maintenance work of navigational markers in the jurisdiction area.This paper tries to provide relevant help and countermeasures for the optimization of anti-interference ability of PLC integrated module of telemetry and remote control equipment of navigational AIDS and to improve the reliability,accuracy and timeliness of navigational AIDS information monitoring and supervision data.
