Undisturbed pump body packing leakage online monitoring device

The invention particularly relates to an undisturbed pump body packing leakage online monitoring device which comprises a microcomputer, a power module, a pump body sampling module, a pump body packing leakage module and a sound alarm module. The power supply module is connected with the microcomputer circuit and supplies power to the microcomputer; the pump body packing leakage module is connected with the pump body sampling module, the pump body sampling module is in communication connection with the microcomputer, and the pump body sampling module collects current signals of the pump body packing leakage drainage pump, converts the current signals into voltage signals and sends the voltage signals to the microcomputer. The microcomputer is used for converting a voltage signal of the pump body packing leakage draining pump into starting interval time data; the sound alarm module is in communication connection with the microcomputer, and when the starting interval time of the pump body packing leakage draina
