How do common geomagnetic sensors work

 

I believe everyone knows what geomagnetic sensors are. The data collection system plays a very important role in the traffic monitoring system. The geomagnetic sensor is responsible for the task of data collection, and the data collected by the sensor plays a very important role in the navigation of billing and timing.

We all know that geomagnetic sensors can detect the status of parking spaces and whether there is a car parked on it. And how is the type of vehicle detected? It uses the influence of the earth's magnetic field when vehicles pass the road to work. Moreover, this sensor is very compact and convenient, has high sensitivity, has a small amount of construction, and can be used for a long time, and there is basically no damage to the road surface.

The role of geomagnetic sensors in the realization of parking guidance and billing functions

The geomagnetic sensor is the front-end sensing device of the ground guidance system. It will accurately lock the staying and leaving time of the vehicle and transmit it to the back-end of the management system to easily obtain information on the number of vacant parking spaces, thereby inducing car owners to stop. In addition, as a new type of electronic timing toll collection device, the geomagnetic sensor is buried under the parking space, and its working principle is not complicated.

Simply put, when a vehicle enters a parking space, cutting the magnetic line of induction will cause a change in the magnetic field. The geomagnetic sensor will then determine that the vehicle has entered the parking space. At the same time, it will start timing and remind nearby toll service personnel to perform services; when the vehicle leaves When berths, prompt the charging service staff to handle the departure process immediately. In this way, citizens don't have to worry about parking too much time. In the meantime, the sensor will automatically scan continuously to check whether the vehicle is still parked.

In addition, the geomagnetic sensor can also realize the parking guidance function. Through the comprehensive statistical analysis of the back-end system, the information on the nearby free parking spaces can be provided on the display screen to better guide the citizens to choose the parking place reasonably. You can also check whether there are free parking spaces through the mobile phone application. The parking space sensor will transmit the parking space information to the mobile phone, so that you can know the parking space information in real time.

When the parking space is in a state for a long time, the sensor will enter the dormant state, reducing the number of scans, which can save power and extend the use time.
