With the development of embedded technology and network technology and the development of intelligent level of embedded terminals,it is possible to implement the grid monitoring system in the monitoring terminal.Monitoring terminal itself has the ability of analyzing and storing the parameters of the grid and also can publish the real-time data to the internet.This article designs the intellective monitor system of the grid based on embed web server BOA.The system can sample the phase voltage and electric current of the grid. With the handle of ATT7022,it published the run parameter of grid to the internet by BOA.The system can effectively monitor the operation state quantity of the equipment of power grid such as current ,voltage,photo corner and so on.The monitoring system has the features of low cost, high reliability and wide range of applications.
