The implementation details of the detection device for the elevator door lock loop short circuit of the present embodiment are specifically described below, and the following description is provided only for convenience of understanding, and is not necessary to implement the present embodiment. The structure of the detection device for the elevator door lock loop short circuit of the embodiment is shown in fig. 1, and the detection device comprises: trigger source 101, safety circuit 102, elevator controller 103, pulse generator 104, isolation device 105 and braking device 106.
Specifically, the trigger source 101 may be an ac power source or a dc power source, and is determined specifically by the brake device 106.
The safety circuit 102 is connected at one end to the trigger source 101 and at the other end to the elevator controller 103, wherein the trigger source 101 is adapted to output a signal to the safety circuit 102 such that the elevator controller 103 can detect the trigger source signal at the connection point with the safety circuit 102.
Wherein the safety circuit 102 comprises at least: a first door lock circuit 1021 and a second door lock circuit 1022. The door lock loop in the elevator includes: in one elevator, the front car door lock loop, the rear car door lock loop, the front layer door lock loop and the rear layer door lock loop can be multiple, and the specific number is determined according to actual conditions. In one example, the first door lock loop 1021 and the second door lock loop 1022 may be a front car door lock loop and a front landing door lock loop, or a rear car door lock loop and a rear landing door lock loop, respectively, of the door lock loops in the elevator.
It will be appreciated that a safety switch circuit is also included in the safety circuit 102 to allow the elevator to function properly.
In a specific implementation, the first door lock loop 1021 and the second door lock loop 1022 are connected in series, and both ends of the first door lock loop 1021 and the second door lock loop 1022 are connected to detection points corresponding to the elevator controller 103, so that the elevator controller 103 can also detect the trigger source signal at the detection points connected to the first door lock loop 1021 and the second door lock loop 1022.

Specifically, under normal conditions, the door lock switches of the front car door lock loop and a certain layer of front layer door lock loop are disconnected, so that the elevator controller can only detect the pulse signal P1 output by the pulse generator at the IN2 detection point, and can not detect signals at other detection points, and if the front layer door lock loop is short-circuited at this time, the elevator controller can detect the pulse signal P1 at the IN2 detection point and the IN3 detection point; if the front car door lock loop is shorted at this time, trigger source signals P0 and P1 are detected at an IN1 detection point and an IN2 detection point; if the front car door lock loop and the front floor door lock loop are shorted at this time, p0+p1+p2 is detected at the IN1 detection point, the IN2 detection point and the IN3 detection point, that is, the elevator controller can determine whether the front car door lock loop and/or the front floor door lock loop of the elevator are shorted according to the signals detected at the IN2 detection point and the IN3 detection point.

In addition, because the signals of the trigger source and the pulse generator are output in real time, the embodiment of the invention can detect the signals of the detection points connected with the first door lock loop and/or the second door lock loop in real time, and can determine whether the door lock loop of the elevator is shorted or not or determine which door lock loop is shorted more efficiently, thereby avoiding the damage caused by the shorting of the door lock loop when the elevator operates.
