摘　　要：采用无人直升机巡线的方式检查高压输电线路可以达到提高巡线效率、及时发现隐患、加快危急状态反应速度、降低劳动强度的目的。文章论述了无人机数据链路的组成,设计了一种基于单片机的数据合码分码链路执行方案,可实现上行遥控信息、任务信息和管理信息同路上传;下行遥测信息、任务信息和管理信息同路下传的功能,对于带吊舱巡检的无人机系统具有一定的通用性。Using the unmanned aerial vehicle （UAV） to survey the high voltage transmission line is very helpful for us to improve the patrol efficiency, discover potential crisis, accelerate reaction speed in crisis and reduce labor intensity. Based on the analysis to the UAV data link, this paper has proposed a scheme of data-combined and data-separated data-links based on MCU, which, using only one channel, has achieved the uplink of remote control command, the task information and the management information at the same time. By using the aforementioned channel, the downlink of telemetry data, the task information and the state of the whole datalink have also been achieved as well. To some extent, the design is considered signifieant to UAV survey system with pod.
