Magnetic sensor
The trigger of the sensor usually includes: switch type, pure mechanical type, single-point electronic type, side impact type, strain type, etc. Internationally, there is no uniform standard for the triggering method of sensors on airbags in automobiles, not only because of the wide variety of sensors, but also because the triggering methods of sensors installed in different positions on the body are also different. In order to enable the sensor to be conveniently installed in each required sensing part, so that it can sense the collision correctly and timely, the magnetoelectric sensor can be selected.
The magnetoelectric sensor can be installed anywhere on the body, as long as some parameter values are slightly adjusted so that it can identify the collision acceleration signal with a peak value of 0588 m/s: and a time pulse of 0-20 ms. As long as the collision acceleration peak value and the time pulse width satisfy the conditions at the same time, a trigger signal will be sent to the airbag to deploy the airbag to protect the human body.
