The Role of Geomagnetic Sensors in the Realization of Parking Guidance and Billing Functions
Geomagnetic sensors can be used to detect the presence of vehicles and vehicle type recognition. The data acquisition system plays a very important role in the traffic monitoring system. The geomagnetic sensor is a key part of the data acquisition system. The performance of the sensor plays a decisive role in the accuracy of the data acquisition system. Geomagnetic sensors can be used to detect the existence and model of a vehicle. It uses the influence of the earth's magnetic field when vehicles pass the road to work. And this kind of sensor is very compact and convenient, the sensitivity is also first-class, the construction amount is very small, but its service life is very long, and the damage to the road surface is also very small. 1. The working principle of geomagnetic sensor in parking service The geomagnetic sensor is the front-end sensing device of the ground guidance system, which can accurately lock the stay and departure time of the vehicle. And transfer these data to...
