Aiming at the problems of high maintenance cost and imperfect functions of traditional power monitoring system servers,the data of each device is collected by STM32 microprocessor,and the remote monitoring adopts Modbus communication protocol and wireless module to send the data to the cloud server to realize data transmission and storage.Finally,a set of user-side power consumption information monitoring system is designed based on China Mobile's OneNET platform.The system can effectively monitor power consumption information,load operation,etc.which is convenient for users to observe the power consumption status more intuitively,formulate more reasonable power consumption planning and improve economic benefits.The experiment results show that the system runs stably and reliably,and meets the national index requirements for power monitoring voltage and current measurement accuracy within 0.5 level.
