基于GSM短消息的变电站无人值班系统

介绍了基于全球移动通信系统(GSM)短消息(SMS)的变电站无人值班系统的结构和功能。该系统是以手机短消息方式将变电站自动化系统内的有关保护装置动作情况、设备运行状况等信息按要求及时发送给相关人员,以便实时获得运行工况。系统由自动化接口、SMS收/发、GSM调制解调器组成。该系统具有系统管理、告警信息发送、数据定时发送、数据查询等功能。系统软件设计采用面向对象的Delphi语言,采用模块化设计和事件驱动机制,通过Socket接口获取自动化系统实时信息,应用Access数据库暂存和管理系统的信息和参数,并给出了突发事件、查询信息子程序流程图。基于GSM短消息的变电站无人值班系统具有良好的实用价值。

Unattended substation system based on SMS of GSM

The structure and functions of unattended substation system based on SMS(Short Message Service) of GSM(Global System for Mobile communications) are introduced.In the system,the information about protection action,device operation and so on is sent to related staff in time by means of SMS.The system consists of automation interface,SMS sending / receiving and GSM modem,with functions of system management,alarm sending,scheduled data sending and data query.The software is programmed with Delphi,an object-oriented language,and the modularization design and event driving mechanism are adopted.The system acquires real-time information of automation system through Socket interface,saves and manages the information and parameters using Access database.Flowcharts of irregular events and information query subprogram are provided.The system is practical.
