Circuit connection monitoring structure and device

The invention provides a circuit connection monitoring structure and device. The circuit connection monitoring structure comprises a first circuit connection end and a second circuit connection end and is arranged in the connection plug of the equipment, so that the circuit connection integrity between the equipment is monitored, and the circuit connection monitoring structure is different from anexternal sensor similar to a proximity switch, is smaller in size and lower in power consumption; a power failure protection circuit is adopted, so that the monitoring device can still monitor the circuit integrity under the condition that the equipment is powered off, and the real-time monitoring of the device is realized; a memory is adopted to store abnormal state signals generated by the microprocessor, so that subsequent workers can check the abnormal state signals conveniently; and a verification module is adopted, so that after the monitoring device finds that an abnormal state entersan alarm state, the monito
