Remote Electric Power Network Monitoring System Based on GPRS

In the past, the managers of the electric power department know the situation whether electric power network works well, by recording all kinds of monitoring data artificially, or setting some observations for video surveillance with the aid of ISDN. While video surveillance has a lot of advantages, there are still many inadequacies, such as, requiring complex digital terminal, responding slowly, building the network on a small scale and costing highly. These constrain the development of it. Through a large number of experimental studies, using the China Mobile´s GPRS wireless communication technology to transmit data, we can simply use the cell phone to complete the data reception. It is fast and cheap, making a good solution to the shortcomings of the video surveillance. In addition, in the aspect of data acquisition, we usually choose expensive A/D converter chip to ensure data´s high accuracy. The author has used V/F chip to meet the required precision through massive successful experiments.
