基于嵌入式系统在电网远程监控中的应用

针对电网远程监控系统的现状和发展趋势,研制了一套基于TCP协议的客户/服务器机制的电网远程监控系统。客户端即电网监测仪,采用PHILIPS公司的LPC2131作为主控芯片,可监测电网实时电压、电流、功率、频率等参数,并通过光纤环网将参数传送给服务器端。服务器端即监控主机,监控软件采用VB和SQL Server数据库技术,具有数据显示、历史数据查询等功能。该系统经测试运行稳定,可靠性高。

Application of Embedded System in Remote Monitor System of the Electrical Network

On the basis of actuality and developing trend in the remote monitor system of electrical network, a monitor system of client/server mechanism based on TCP protocol is designed. The client, which is the electrical network monitor, uses LPC2131 chip of FHILIPS Company as the main-control chip. It can monitor so many electric parameters such as voltage, current, frequency and power on real time, and deliver these parameters to the servers through fiber ring network. The servers are the monitoring host at the same time; the monitor software uses Visual Basic and SQL Server database technology to realize functions, such as data displaying, historical dada enquiring and so on. From the result of test, the system has a good stability and reliability.
