Title: Intelligent electricity-filch monitoring device based on power line transmission technology
Abstract: An intelligent electricity-filch monitoring device based on power line transmission tech-nology is introduced,which consists of monitoring unit,CPU,power line transceiver and so on. The secondary voltage and secondary current of three-phase three-wire power supply are real-timely moni-tored. The phase relationship between voltage and current is analyzed to detect the electricity steal by means of improper connection of secondary phase lines of current and voltage,and the power consumption conditions and power line connections are recorded. Microcomputer simulates the special working mode of Neuron chip in serial communication to control the double-band carrier power line transceivers,and transmits user's real-time power consumption information with power line via repeaters. According to the information transmission way of power line transceiver,the main structure of CAN 2.0B is adopted in the communication protocol and the sum check is added in application layer to enhance the reliability of data transmission.
