A scheme of telemetering and preventing electric larceny system based on GPRS communication system

For the power supply department, the key problem is hard to find a suitable and cheap way to not only collect huge number of the vastly distributed meters, but also calculate the balance of electric quantity and detect the nontechnical loss (such as electric larceny) automatically. This paper analyzes the structure and principle of the telemetering and preventing electric larceny system based on the public mobile data communication network GPRS. This system realizes the real time and accuracy of reading meter. Meanwhile, for the unique addressing mode, the monitoring software of this system can monitor the process of power provision and consumption, compare and analyze the data in real-time to find the nontechnical loss and measure the power or water supply system weak points; The power supply department can calculate the line loss according to the real-time data; The strong monitoring software also provides some analytic information about the real-time measurements of electrical energy quantities and alarms of electric larceny. The application shows that this system has the character of cheapness, high efficiency, practicability and so on.
