Network modularization electric power tolerance monitoring device

A networking modularization electric power measurement monitoring device relates to the technique field of electric power measurement monitoring, which aims at solving the problems of single function, poor commonality and single network communication interface of the existing electric power measurement monitoring device as well as the problems of incapable of realizing remote-monitoring and data sharing of large range and spanning networks. The data terminal of an electric power parameter collection module (4), the data terminal of a CAN/DeviceNet communication interface module (5) and the data terminal of a RS485/Modbus communication interface module (6) are all connected with the data control output/input terminal of a micro-control module (1); the signal output terminal of a current transformer group (4-1) is connected with the input terminal of the electric power parameter collection module (4). The monitoring device can measure and detect the power consumption amount, the voltage of each phase and the cu
