摘　　要：针对一种送电线路状态监测终端设计的要求,提出了相对应的解决方案,将其划分为终端本体、接触感知单元和无接触感知单元三部分,降低了设计复杂性。其中,终端本体又分为本地太阳能电源和监测终端两部分,本地太阳能电源采用恒压和浮充方式对蓄电池充电,并对蓄电池进行过放电保护。监测终端使用一种S5PV210核心板作为处理器,裁剪其评估板得到基本的终端平台,保留其中的视频摄像和SD卡接口电路,实现视频采集和文件存储功能,扩展无线和有线通信接口与感知单元进行通信,扩展4G移动通信接口与控制中心通信,实现信息上传功能。项目开发完成之后在实验室对所设计功能和部分性能指标进行了验证测试,与预期目标相符。According to the implement technical requirements for a status monitoring terminal of power transmission line,the corresponding overall solution was proposed,and the unit was divided into terminal body,contact sensing unit and non⁃contact sensing unit to reduce the design complexity.The terminal body was divided into local solar power supply and status monitoring terminal also.The local solar power supply used constant voltage and float charging mode to charge the battery,and provided over discharge protection for the battery.an S5PV210 core board was used as the processor,and its evaluation board was cut to get the basic terminal platform.The video camera and SD card interface circuit were retained to realize the video capture and file storage functions.The wireless and wired communication interfaces were extended to communicate with the sensing unit to achieve the status parameter acquisition function.The 4G mobile communication interface were extended to communicate with the control center to realize the information upload function.After the completion of the project development,some functions achieved were tested in the laboratory,and the requirements of the specification could be met.
