Equipment information acquisition system of machine networking system

The invention belongs to the technical field of intelligent production, and particularly relates to an equipment information acquisition system of a machine networking system. The equipment information acquisition system comprises an equipment end acquisition box, a workshop end receiving box and a server, the equipment end acquisition box comprises an alternating current transformer, an alternating current acquisition module and a wireless WIFI sending module; and the workshop end receiving box comprises a 4G wireless router and an industrial personal computer, and the industrial personal computer receives a Modbus-TCP message forwarded by the 4G wireless router and compares the Modbus-TCP message with a set equipment state current threshold so as to calculate the working state of the equipment. Only the equipment end acquisition box needs to be installed at a total power supply position of equipment, the current of the motor for driving equipment to work is acquired through an alternating current transforme
