In an embodiment, a method for detecting an operation state of a car door contact is provided, which is described by taking an example that the method is applied to an elevator master control system 102 in fig. 1 as an example, as shown in fig. 2, and fig. 2 is a schematic flow chart of the method for detecting an operation state of a car door contact in an embodiment, and includes the following steps:
step S210, when the contact to be detected of the car door acts, the detection position information of the car door relative to the set reference object is obtained.
The detection contact of the car door is arranged on the car door switch, when the elevator master control system sends a door closing instruction, the car door is closed, the car door contact is closed, and the car door contact is used for indicating the closing condition of the car door. The car door contact can be a door lock contact and can also be a closing contact.

And step S250, comparing the difference value with the characteristic value, and obtaining the running state information of the contact to be detected according to the comparison result.
The operation state information of the contact to be detected is used for determining the difference between the current operation state and the failure critical state of the contact to be detected, and may include a normal operation state of the contact to be detected and an early warning state of the contact to be detected. And when the comparison result is smaller than the set value, judging the normal operation state of the contact to be detected, and when the comparison result is larger than the set value, judging the early warning state of the contact to be detected.
