Problems solved by technology
[0002] At present, people use elevators more and more frequently, but the safety of elevators has not been effectively solved. A large part of the reason is that the elevator abnormal data has not been collected in time and accurately, and the abnormal data has not been further located and analyzed.
[0003] At present, the elevator vibration detection and means mainly use the three-axis acceleration sensor, which uses the change of acceleration to detect the vibration of the elevator. The height changes, especially the real-time change of the height of the elevator. At this time, the acceleration is used to calculate, and there is a certain error
In addition, the sensitivity of the three-axis acceleration sensor is low, and small vibrations may not be detected

The invention provides an elevator vibration detection system which includes an optical fiber vibration detection module installed on the top of an elevator lift car and a data processing module. Theoptical fiber vibration detection module is used for detecting vibration information of an elevator and providing the vibration information to the data processing module, a plurality of first reference information is pre-stored in the data processing module, and the data processing module enables the vibration information to be compared with the first reference information and forms elevator vibration state information based on a comparison result. By means of the system, a photoelastic effect of optical fibers is used, an optical fiber vibration sensor is used for detecting vibration of the elevator, the system is high in sensitivity and accurate in detection, signals can be divided into different types so as to be compared with the reference information, and accurate detection of vibration parts and vibration types is achieved.
