Technical Field

[0001] The utility model relates to the technical field of vibration detection, in particular to an elevator car vibration detection device and an elevator. Background Art

[0002] In the past, industry standards did not require elevators to be connected to the Internet. Some elevator manufacturers' elevators could be connected to the Internet, but only the manufacturers could obtain elevator data. With the development of Internet of Things technology, there is a demand for elevator networking. However, for the large number of existing elevators, if they need to be internally modified one by one, it will generate a huge workload and many unpredictable hidden dangers. Therefore, the elevator aftermarket was born, that is, without modifying the elevator's own circuit, a data acquisition device is installed on the elevator to collect elevator data.

[0003] In the prior art, an elevator car will generate certain vibrations when it stops running, but as the usage time increases, the vibration amplitude will increase, which will affect the safe operation of the elevator car. The existing elevator car lacks a vibration detection device and cannot detect the vibration value of the elevator car in time. Utility Model Content

[0012] 1. The utility model can install the installation device at the top, bottom or inside of the elevator car body according to the needs, which does not affect the operation of the elevator car body. The touch sensor and the induction paddle in the device are electrically connected to the external control terminal. After the induction paddle triggers the induction signal, it is transmitted to the external control terminal through the touch sensor.
