摘要
基于全球移动通信系统(GSM)技术的电网电压监测系统由多台短信电压监测仪、GSM网络、IBM-PC586上位机及电压监测统计管理软件4部分组成。介绍了短信电压监测仪的硬件(电压/电流信号的采样、滤波、信号调理、A/D转换、显示、时钟、GSM-Modem接口等)电路及其功能。讨论了GSM通信发送/接收短信息的编码规则与步骤以及短信电压监测仪的短信处理。
The power network voltage monitoring system based on GSM(Global System for Mobile communication) consists of several SMS(Short Message Service),based voltage monitoring instruments,GSM network,IBM - PC586 superordinate computer and statistical management software for voltage monitoring. Its hardware is introduced,such as circuits of voltage / current signal sampling,filtering,conditioning,A / D converter,display,clock,GSM- modem interface and so on,and its functions are described as well. The coding rules and steps of receiving / transmitting short messages through GSM and the further processing by voltage monitoring instrument are discussed.
