The following describes the details of the detection device for detecting a short circuit in an elevator door lock loop in the present embodiment, and the following description is only provided for the sake of understanding, and is not necessary to implement the present invention. The structure of the detection device for the short circuit of the elevator door lock loop of the embodiment is shown in fig. 1, and comprises: trigger source 101, safety circuit 102, elevator controller 103, pulse generator 104, isolation device 105 and brake 106.
Specifically, the trigger source 101 may be an ac power supply or a dc power supply, and is determined by the brake device 106.
The safety circuit 102 is connected at one end to a trigger source 101 and at the other end to the elevator controller 103, wherein the trigger source 101 is arranged to output a signal to the safety circuit 102 such that the elevator controller 103 can detect the trigger source signal at the point of connection to the safety circuit 102.
The safety circuit 102 includes at least: a first door lock loop 1021 and a second door lock loop 1022. A door lock circuit in an elevator comprising: the elevator door lock system comprises a front car door lock loop, a rear car door lock loop, a front layer door lock loop and a rear layer door lock loop, wherein in one elevator, the number of the front layer door lock loop and the number of 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 floor door lock loop, or a rear car door lock loop and a rear floor door lock loop, respectively, among door lock loops in the elevator.
It will be understood that a safety switch circuit is also included in the safety circuit 102 to allow normal operation of the elevator.
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 detect a trigger source signal at the detection points connected to the first door lock loop 1021 and the second door lock loop 1022.

The isolation device 105 may be an optocoupler or a metal oxide film capacitor.
In one example, the device for detecting the short circuit of the elevator door lock loop of the embodiment further comprises a braking device 106, wherein the braking device 106 is connected with the safety loop 102 to brake the elevator so that the elevator is normally stopped.

referring to fig. 1, if the first door lock loop 1021 is a front car door lock loop, and the second door lock loop 1022 is a front door lock loop, where there are multiple front door lock loops, that is, each floor of the elevator includes one front door lock loop, if the elevator stops at a certain floor and the front door of the elevator is opened, then it starts to detect whether the elevator door lock loop of the floor is shorted.
Specifically, under normal conditions, the door lock switches of the front car door lock loop and the door lock switch of a certain layer of front layer door lock loop are both disconnected, the elevator controller can only detect the pulse signal P1 output by the pulse generator at the detection point IN2, and cannot detect signals at the rest detection points, and if the front layer door lock loop is short-circuited at the moment, the elevator controller can detect the pulse signal P1 at the detection point IN2 and the detection point IN 3; if the front car door lock loop is short-circuited at the moment, trigger source signals P0 and P1 are detected at a detection point IN1 and a detection point IN 2; if the front car door lock loop and the front layer door lock loop are IN short circuit at the moment, P0+ P1+ P2 are detected at an IN1 detection point, an IN2 detection point and an IN3 detection point, namely, the elevator controller can judge whether the front car door lock loop and/or the front layer door lock loop of the elevator are IN short circuit or not according to signals detected by the IN2 detection point and the IN3 detection point.
If the first door lock loop 1021 is a rear car door lock loop and the second door lock loop 1022 is a rear door lock loop, if the elevator stops at a certain floor and the rear door of the elevator is opened, the manner of detecting whether the elevator door lock loop of the floor is short-circuited is substantially the same as the above-mentioned detection manner, and details are not repeated here.
The above examples in the present embodiment are for convenience of understanding, and do not limit the technical aspects of the present invention.

In addition, because signals of the trigger source and the pulse generator are output in real time, the embodiment of the invention can detect signals of detection points connected with the first door lock loop and/or the second door lock loop in real time, and more efficiently determine whether the door lock loop of the elevator is short-circuited or determine which door lock loop is short-circuited, thereby avoiding the harm caused by the short-circuiting of the door lock loop when the elevator runs.

The first door lock loop 2021, the second door lock loop 2022, the third door lock loop 2023 and the fourth door lock loop 2024 may be any combination of the following door lock loops: the car door lock loop comprises a front car door lock loop, a rear car door lock loop, a front layer door lock loop and a rear layer door lock loop.
The uses of the trigger source 201, the safety circuit 202, the elevator controller 203, the pulse generator 204, the isolation device 205 and the braking device 206 in this embodiment are substantially the same as in the first embodiment and will not be described again here.
