The invention discloses a real-time monitoring device and method for the engagement depth of an elevator door lock. The device comprises a digital angle sensor, a signal processing unit, a Hall current sensor, an operational amplifier, a microprocessor CPU, a key and an elevator main control board. A door lock of each landing door is provided with a digital angle sensor, and each digital angle sensor is in communication connection with the microprocessor CPU through a signal processing unit. The Hall current sensor is in signal connection with the microprocessor CPU through the operational amplifier; the key is connected with the microprocessor CPU; and the microprocessor CPU is in communication connection with an elevator main control board. The system can monitor the meshing or abnormal working of the door lock in real time, can memorize and store the track of the door lock in the normal working state, and can send the abnormal conditions such as excessive meshing and jamming to the mobile phone of a maintainer or an inspector in the form of a short message in the first time when the door is closed, so that the safety of the maintainer or the inspector is ensured. And elevator safety accidents are effectively avoided.
