Monitoring system and method of electromagnet backup protection device

The invention provides a monitoring system and method for an electromagnet backup protection device, and the system comprises a handheld electromagnet backup protection device and an equipment terminal. The handheld electromagnet backup protection device comprises a left hand handheld electromagnet, a right hand handheld electromagnet, a data processing module, an electromagnet state acquisition module and an electromagnet control module, and the electromagnet state acquisition module, the electromagnet control module and the equipment terminal are all connected with the data processing module. The left hand-held electromagnet and the right hand-held electromagnet are connected with the electromagnet state acquisition module and the electromagnet control module at the same time. The monitoring method specifically comprises the steps of collecting weight data and a working state, calculating electromagnetic force of the left hand-held electromagnet and the right hand-held electromagnet according to the weight
