The invention discloses an elevator door lock contact resistance value detection and voltage monitoring system and method. The system comprises a door lock contact resistance value detection loop arranged behind a safety loop. The door lock contact resistance value detection loop comprises a constant current source, a plurality of detection points, a plurality of contact switches and a processing unit which are connected in series; the processing unit is communicated with the monitoring platform through the Internet of Things; the detection points comprise a car door lock detection point, a hall door lock and voltage detection point and an auxiliary detection point; the contact switches comprise a first switch, a second switch, a third switch and a fourth switch. The principle that a direct-current constant-current source generates direct-current voltage drop through a resistor and a data processing technology are directly applied to an elevator system, and detection of resistance values of a car door lock and a hall door lock is simply and effectively achieved. A voltage value detection technology is used for monitoring the voltage value at the front end of the contactor, and warning reminding can be given out. The device has the advantages that the door lock resistance value and the front end voltage value of the contactor can be monitored in real time, only targeted maintenance is needed, and layer-by-layer troubleshooting is not needed.
