摘要
研制了一种基于多种通讯方式的SF6断路器气体监测模块。硬件线路以单片机AT 89C 55W D为核心,分别采用单总线数字温度传感器DS18B20和压力传感器SPS19测量SF6的温度和压力。本文从系统组成框图、硬件设计以及程序流程等几个方面介绍了该监测模块的设计过程,并且详细的介绍了硬件部分的电路。
A kind of monitoring module of SF6 circuit breaker based on multi- communication mode is designed. The hardware has been finished mainly on a single chip computer AT89C55WD. The SF6 gas temperature sensor is DS18B20, and the SF6 gas pressure sensor is SPS19. The main principle and composition of this moduie has been described in detail.
