基于电力线通信的远程电能计量监控系统设计

为了解决目前电业管理中存在的电能非法使用问题，提出了一种基于电力线通信网络的远程电能计量监控方法。该系统具有电能的自动计量、远程数据传送、防止非法用电等功能。给出了防止非法用电的系统结构框图，设计了基于ST7538的电力线通信模块和基于ATT7022A的电能计量监控模块，给出了其硬件结构图及软件程序流程图。最后，对该系统进行了电能计量精度测试和电力线通信可靠性测试，给出了测试数据。经过初步试验证明本设计模块是有效的。

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.
