Design of remote power-metering monitoring system based on power line communication

In order to solve the problem such as illegal power usage in the power management is provided, a remote power measure monitoring method based on power line communication. The system has the functions of power-measure, remote data transmission and guarding against illegal power usage. The structure of detection system of illegal electricity usage is provided, the power line communication module based on ST7538 and the power-measure monitoring module based on ATT7022A are also depicted. In additional, the structure of hardware and the main program flow diagram are designed. Last, the precision of the power-measure monitoring module and the reliability of the power line communication are tested and the test data is described. The design of the module is proved effectively.
