Electricity detection system based on power line carrier communication

In order to reduce communication invest, the electricity detection system based on power line communication (PLC) was studied in this paper. At first, the research status of PLC technology and application prospects was expounded. Then, the overall design of the system and modules was introduced. Next, the working principle of each module respectively was analyzed, mainly in the power line communication module, power detection module and the computer software based on MODBUS. Finally, the electric energy testing system was built, and achieves accurate detection data of electrical equipment by monitor computer.
