Embodiment Construction

[0048] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0049] The elevator brake detection method provided by this application can be applied to such as figure 1 shown in the application environment. Wherein, during the braking stroke of the elevator brake, the sensor can be used to obtain a measurement value, which can be a distance value, or a current value or a voltage value, and sent to the data acquisition and processing unit of the elevator. The data acquisition and processing unit can obtain the measured value. If the measured value is a current value or a voltage value, the distance value can be obtained after convers...

Abstract

The application provides an elevator brake detection method, device, computer equipment and storage medium. The method includes: obtaining the initial distance from the sensor of the brake to be detected to the armature fixed by the brake pads, and obtaining the working distance from the sensor of the brake to be detected to the armature fixed by the brake pads during the braking process, and obtaining according to the working distance The maximum distance and the minimum distance from the sensor to the armature fixed by the brake pad in the braking stroke, according to the corresponding relationship between the pre-configured fault type and at least one of the initial distance, working distance, maximum distance and minimum distance, to obtain each fault type corresponding to at least one distance, so as to determine the fault state of the brake to be detected. During the braking process, the distance from the brake sensor to the armature fixed by the brake pad can determine the fault state, avoiding the action delay when detecting through the micro switch, and improving the efficiency and accuracy of elevator brake fault detection.

Description

technical field [0001] The present application relates to the technical field of elevator detection, in particular to an elevator brake detection method, device, computer equipment and storage medium. Background technique [0002] The brake is one of the important safety components of the elevator, and it is particularly important to detect the operating state of the brake. Micro switches are common elevator brake detection tools. During the operation of the brake, the output signal of the micro switch is associated with the lifting and releasing of the brake. [0003] In the current technology, when the brake is lifted or released, there is no regularity between the brake operation process and the final state and the signal output by the micro switch, resulting in a delay in the action of the micro switch to obtain the brake, and the detection accuracy is low. . Contents of the invention [0004] Based on this, it is necessary to provide an elevator brake detection met...
