Embodiment 1

[0047] Please refer to figure 1 , the embodiment of the present application provides a method for detecting abnormal operation of an elevator, the method comprising:

[0048] S101: During the running of the elevator, detect a first group of operating parameters of the elevator through a first detection method, and simultaneously detect a second group of operating parameters of the elevator through a second detection method different from the first detection method; wherein , the operating parameters include the position parameters of the elevator car;

[0049] S102: Judging whether the detection results of the first group of operating parameters and the detection results of the second group of operating parameters conform to a preset corresponding relationship, and obtaining a judgment result;

[0050] S103: When the judgment result is negative, determine that the elevator is running abnormally; usually, the elevator running abnormally is manifested as an abnormal position of...

Embodiment 2

[0085] Based on the same inventive concept, the embodiment of this application also provides a device for detecting abnormal operation of elevators, please refer to Figure 4 , the device includes:

[0086] The operating parameter detection unit 401 is used to detect the first group of operating parameters of the elevator through the first detection method during the operation of the elevator, and at the same time detect the first group of operating parameters of the elevator through the second detection method different from the first detection method. The second set of operating parameters;

Abstract

The invention discloses a method and a device for detecting abnormal operation of an elevator, and aims at solving the technical problems in the prior art that an elevator control system cannot automatically detect whether the position of an elevator car is abnormal or not. The method comprises the following steps: detecting a first group of operation parameters of the elevator through a first detection manner in an operation process of the elevator; meanwhile, detecting a second group of operation parameters of the elevator through a second detection manner, which is different from the first detection manner; judging whether a detection result of the first group of operation parameters and a detection result of the second group of operation parameters accord with a pre-set corresponding relation or not, and obtaining a judging result; when the judging result is negative, determining that the operation of the elevator is abnormal. The technical effect of automatically detecting the abnormal position of the elevator car by the elevator control system is realized.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to a method and device for detecting abnormal operation of an elevator. Background technique [0002] With the development of society, high-rise buildings abound, and elevators are an indispensable "means of transportation" between the floors of each high-rise building. The elevator system includes: elevator shaft, car, running track set on the shaft wall, pulley device and elevator drives. Using the pulley principle, the two ends of the pulley rope are connected to the car and the elevator driving device respectively, and the driving device drives the pulley to rotate clockwise or counterclockwise under the control of the elevator control system to lift or lower the car, thereby realizing the up and down operation of the elevator Features. Usually, a mechanical switch is set on the inner wall of the elevator shaft, such as a forced deceleration switch, a limit position switch, ...
