基于嵌入式Modem的漏电监测系统

Leakage Current Detect System Based on Embedded Modem

介绍了一种基于嵌入式Modem的漏电监测系统。该系统预留RS— 4 85通信接口 ,作为跟变电站自动化系统的接口 ,可以通过跳线开关选择使用 4 85接口传送数据 ,报文格式采用变电站自动化系统中常用的 10 1规约 ,因此可以纳入到变电站自动化系统中 。

A system of detect leakage current which based on the embedded Modem is introduced.The communicate interface of RS—485 is reserved to link with substation automation system.The data can be transmitted from 485 interface selected by jumper,and use 101 protocol which used by substation automation system as the format of message,so it can be accepted to monitor and control uniformly in transformer substation automation system.
