遥控遥测是无人机与地面控制人员信息交互的基本手段。针对某型机载图像/遥测发射机工作异常,从工作原理着手,进行机理分析,建立故障树,逐层深入排查,最终完成故障定位和排除。该方法可为同类设备故障排除提供借鉴。 Remote telemetry is the basic means of information interaction between UAV and ground control personnel. Aiming at the abnormal operation of a type of airborne image / telemetry transmitter, the paper starts with the principle of operation, analyzes the mechanism, builds the fault tree, and performs in-depth investigation one by one, finally locating and eliminating the fault. This method provides a reference for troubleshooting similar devices.
