Considering the complex circuit layout of the current electricity measurement and acquisition system and the weak ability of monitoring and judging electricity theft, this paper studies an embedded electricity measurement and acquisition system. There are two parts in the embedded power metering system: wireless monitoring device for high voltage side power consumption information and remote monitoring device for low voltage side power consumption information. The working principle of the wireless monitoring device for high-voltage side electrical information is to collect the circuit information on the high-voltage side, and then transmit the information to the remote monitoring unit through the transmitting module. The remote monitoring device of low-voltage side power consumption information directly identifies the power consumption information of each user, and then transmits the result of identification analysis to the information database of the monitoring main station. The experimental results show that the data detected by the high-voltage wireless detection device can not coincide with the data curve obtained by the low-voltage wireless detection device, which shows that the device can detect the operation of human power theft, and verifies that the embedded power metering and acquisition system studied in this paper can be implemented. Accurate identification of stealing electricity.
