基于RN8302和Python的电能测控系统设计

Design of Energy Measurement and Control System Based on RN8302 and Python

针对传统电能测控系统存在准确度不足、通信方式单一等问题,设计了基于RN8302和Python的电能测控系统。该系统采用计量芯片RN8302实时采集电网电压、电流信号,经SPI接口将计量、报警等数据传输至MCU,再由Wi-Fi将数据上传至测控中心。测控中心采用Python设计人机交互界面,实现数据的存储、查看以及显示等功能。最后,采用该系统对某学校三栋楼电能使用情况进行监控,实验结果表明,系统工作稳定、可靠,有很强的实用价值。

An energy measurement and control system based on RN8302 and Python was designed to solve the problems existing in traditional measurement systems,such as lack of precision and single communication method.The system collecs the grid voltage and current signals through RN8302 in real time,the metering and alarming data are transmitted to the MCU through the SPI interface,and the data are sent to the measurement and control center through Wi-Fi.The measurement and control center is designed based on Python to implement functions such as data storage,viewing and display.At last,using this system to monitor the power usage of three buildings in a school,the experimental results show that the system is stable,reliable,and has strong practical value.
