Method and device for determining working state of elevator, terminal equipment and medium

The invention is suitable for the technical field of mineral mining, and provides a method and device for determining the working state of an elevator, terminal equipment and a medium, and the method comprises: collecting multiple vibration signals of all parts of the elevator; separating a target vibration signal of which the vibration amplitude is greater than a preset value from each vibration signal; acquiring time domain characteristics of the target vibration signal; performing wavelet decomposition on the target vibration signal to obtain a plurality of vibration components of the target vibration signal; reconstructing the plurality of vibration components to obtain frequency domain characteristics of the target vibration signal; and based on the frequency domain characteristics and the time domain characteristics, determining the working state of each part of the elevator, wherein the working state comprises a normal working state or a fault state. Through the method, the fault of the elevator can be
