Informatized network and energy monitoring system for grinders

The utility model discloses an informatized network and energy monitoring system for grinders, which comprises a PLC (programmable logic controller), a motion controller, a frequency converter, a servo driver, a human-machine interface and an electric energy meter. Information of the frequency converter is transmitted to the PLC to be stored in a corresponding address through a PROFIBUS-DP (profibus decentralized periphery) bus, information about the state of the servo driver is transmitted to the motion driver through a PROFIBUS-DP (profibus decentralized periphery) bus and is transmitted to the PLC to be stored in a corresponding address through a PROFIBUS-DP (profibus decentralized periphery) bus, energy data of the electric energy meter is transmitted to the PLC through a PROFIBUS-DP (profibus decentralized periphery) bus, the PLC is in multipoint connection with an MPI (message passing interface), and the motion controller respectively transmits the data to the human-machine interface through Ethernet. The informatized network and energy monitoring system for the grinders is capable of monitoring the information about motion state and energy of the grinders in real time when in running and is used for storing the data, thereby being favorable for testing of failure causes and capable of performing energy management of the grinders.
