Multi-level vibration detector based on electromagnetic induction

The present invention relates to a multi-level vibration detector based on electromagnetic induction and is characterized in that the detector comprises a first level vibration detection device and a second level vibration detection device above the first level vibration detection device. The first level vibration detection device and the second level vibration detection device are connected through a fixed bolt. The first level vibration detection device comprises a first level vibration detection device shell, a first level vibration indication lamp, a magnet support frame, a magnet, a coil support frame, a coil, a commutation module and a rechargeable battery. The first level vibration detection device shell is a square shell and is equipped with a rotary switch, a first level vibration indication lamp display port, a rechargeable battery shell and a first level vibration detection device safety lock. The rotary switch comprises a first level vibration detection device control switch and a second level vibration detection device control switch, and one end of the first level vibration detection device control switch is connected to the commutation module.
