摘　　要：FTU安装于10kV配网架空线上,操作维护很不方便。针对这种现状,本文提出了基于无线UART的FTU系统设计思路。在嵌入式操作系统的基础上,FTU采用了无线UART的硬件设计方法,软件设计上考虑了实时库、历史库、对上规约库与调试模块之间的接口和注册机制。无线UART的驱动模块设计采用了广播和点对点模式相结合的方法。搭建试验平台与RS232方式进行了对比试验和分析,试验结论表明该设计方案切实可行。研发的FTU系统已经成功应用在青海等地,运行结果可靠稳定,减少了用户的维护工作量。FTU installed in overhead online on 10kV distribution grid,operation and maintenance is very inconvenient.For this situation,this paper presents the design of FTU＇s system based on wireless UART.In the embedded operating system,FTU＇s hardware is designed on wireless UART.In software＇s design,the interface and register mechanism of debugging module with real time database,history database and remote protocol database is considered.Wireless UART driver is designed with a combination of broadcast and point to point method.Build platform to compare with RS232,the result shows that the design is feasible.The FTU system has been successfully applied in Qinghai and other places.The result of application is reliable and stable,and can reduce user＇s maintenance.
