Problems solved by technology

However, most of the detection of elevator faults in the current technology can only be detected when the elevator has failed. It can be seen that it does not have an early warning function, and if someone takes the elevator when it fails, it may be dangerous, so it is necessary to make improvements.

Abstract

The invention discloses an early warning system for an elevator fault and an early warning method for the elevator fault. The system comprises a monitoring center, a tractor sensor arranged on a tractor, an elevator car sensor on an elevator car, and a noise sensor arranged outside the elevator car, wherein the tractor sensor, the elevator car sensor and the noise sensor acquire vibration data and noise data of an elevator under different running stages, and transmit the data to the monitoring center, the monitoring center carries out fast fourier transform on the data, to obtain a vibration spectrogram and a noise spectrogram of the elevator under the different running stages, and compares with the vibration spectrogram and the noise spectrogram of the elevator under a normal running stage. The amplitude values of the frequency ranges are compared whether to be abnormal or not, so that the early warning of the elevator fault can be realized. According to the system disclosed by the invention, the fault condition of the elevator can be effectively forecast, the running safety of the elevator can be further improved, and the normal running of the elevator can be guaranteed.

Description

technical field [0001] The invention relates to an elevator fault early warning system and an early warning method thereof. Background technique [0002] Elevators are widely used in modern buildings, and it can be said that they are inseparable from people's daily life. During the operation of the elevator, it is necessary to ensure the overall safety performance, which requires the elevator to be able to self-diagnose in real time and detect whether each component is working normally. However, most of the current technology can detect elevator faults when the elevator has failed. It can be seen that it does not have an early warning function, and if someone takes the elevator when it fails, it may be dangerous, so it is necessary to make improvements. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides an elevator failure early warning system and an early warning method thereof, which can monitor the ...
