基于STM32的MOA无线在线监测系统设计

为了实时、准确地了解MOA工作状况,提出了一种MOA无线在线监测的方案。采用基于Cortex-M3内核的ARM处理器STM32作为主控芯片,通过CC1100无线通信芯片对MOA的泄漏电流和雷击动作次数信息进行无线传输。MOA无线在线监测系统由若干个监测模块、中央结点及后台组成,监测模块内设计了泄漏电流采集、雷击次数采集、无线收发等电路。

Design of MOA Wireless On-line Monitoring System Based on STM32

In order to find out the real-time working condition of MOA accurately,a new method is suggested to monitor the metal-oxide surge arrester on-line by wireless means in this paper.ARM processor STM32 based on Cortex-M3 core was used as a major controlling chip.The data of MOA leakage current and lightning-stroke action number were transmitted by using wireless communication chip CC1100.This system includes some monitor modules,central crunodes and backstage system.Circuits of leakage current collection,light...
