Abstract

The invention relates to an elevator drag brake fault detecting system, method, device and equipment as well as a storage medium. The elevator drag brake fault detecting system comprises audio collectors, current collectors and a processor, wherein each audio collector is connected to the processor for collecting an audio signal emitted by a traction wheel and a brake plate of each brake when an elevator car operates, and outputting the audio signal to the processor; the current collectors are connected to the processor for collecting a working current signal of a motor when the elevator car operates, and outputting the working current signal to the processor; and the processor is used for extracting audio characteristics of the audio signal, calculating a target current effective value which corresponds to the working current signal, and identifying elevator drag brake faults according to the audio characteristics and the target current effective value. According to the embodiment ofthe invention, accurate detection on light drag brake faults of the elevator is realized, loss of a brake is prevented from being quickened while the elevator operates in a light drag brake state fora long term, and the risk that the service life of the elevator is shortened is reduced.

Description

technical field [0001] The invention relates to the technical field of elevator detection, in particular to an elevator drag brake fault detection system, method, device, equipment and storage medium. Background technique [0002] The brake of the elevator, that is, the brake is an important device that keeps the elevator in a static state when it stops running. It is an electromechanical device that prevents the elevator from moving again when the elevator car is at rest and the elevator motor is in a power-off state. When the power is on, the brake is released, and the elevator car can run. When the power is off, the brake is tightened, and the elevator car remains stationary. In actual use, if the brake has long-term brake failure and wear, resulting in insufficient brake torque, it may cause the elevator to slide to the top and cause a safety accident. [0003] However, at present, if the elevator is dragging, unless the fault of the dragging brake is very serious, the ...
