Abstract: In order to meet the demand for statistical analysis of the direct current energy consumption and cost allocation for various users in the iron tower base station, a DC energy metering device based on Hall sensor is designed and studied to measure and monitor the direct current power usage at the iron tower base station. Firstly, the overall design scheme of the DC energy metering device is elaborated. Secondly, the measurement principle of the Hall current sensor is analysed. Finally, the software and hardware design of the device is discussed. The application test results show that the designed metering device achieves a measurement accuracy level of 1, with a total power consumption of less than 2 W, stable performance, and meets the technical specifications of the iron tower base station. It meets the technical development needs for the application of direct current power supply in the communication scenarios of the iron tower base station.

Keywords: Hall sensor; DC metering; RS485; iron tower base station.
