針對GIS傳統在線監測時現場數據不能及時傳輸，導致故障不能及時的預測、報警和處理等問題，開發了基于GPRS 的GIS遠程在線監測系統。該系統以AT89S51為主控制芯片，重點闡述 GPRS的組網方式以及具體實現過程，并在LabWindows/CVI下編寫PC端服務器程序。通過工程實踐證明，本系統能準確、可靠、實時對GIS局部放電進行測量、發送、管理。

　　Abstract:

　　The traditional online monitoring method cannot transmit the measured data in time，and the malfunction of GIS cannot be forecasted，alarmed and treated. To solve the above problem，a method of remote monitoring system for GIS based on GPRS was brought out in this paper.The paper introduced the design of monitoring system based on AT89S51，focused on the networking modeand specific implementation procedure of GPRS， server designed on LabWindows/CVI platform.Using the advanced communication mode，the system is remarkablyreal-time，wide range and low cost.In the view of the features mentioned above and proved by engineering practice， this system is able to measure partial discharge of GIS as well as ensure the accurate and real-time monitoring results.
