Description

Vibration sensor

Technical Field

The present utility model relates to a vibration sensor.

Background

The conventional vibration sensor includes a sensor head, a sensor cable connected to the sensor head, and an injection molded part. The injection molding part wraps the end part of the sensor and the sensor head part in an injection molding mode. The end of the sensor is provided with a wire and an insulating layer positioned outside the wire. Vibration sensors are used in battery packs that need to detect small vibrations of the battery pack and convert the small vibration signals into electrical signals. The vibration sensor ECU unit amplifies and filters the electric signal output by the vibration sensor sensing unit, converts the analog signal into a digital signal through the microprocessor, obtains an effective vibration amount through a correlation algorithm, and finally transmits the effective vibration amount to the whole vehicle battery BMS control system or other ECU units through the communication port.
