Problems solved by technology

For example, only relying on the installation of a geomagnetic detection module in the middle of the parking space to detect whether there is a vehicle in the parking space by detecting the change of the magnetic field lines of the geomagnetic field on the parking space. However, the accuracy of the single geomagnetic vehicle presence detection method is relatively low. When the magnetic field changes are not obvious, it is easy to miss detection and false detection
Another example is to use ultrasonic detection to detect whether there is a vehicle in the parking space. However, a single ultrasonic detection is prone to failure due to external influences. , prone to omissions and false detections

Abstract

The present invention provides a vehicle presence detection method and system. The method includes: using a geomagnetic vehicle detector and a distance detector to cooperate to detect whether there is a car in the corresponding parking space; obtaining the geomagnetic value detected by the geomagnetic vehicle detector and the The distance information detected by the distance detector; according to the geomagnetic value and the distance information, it is judged whether the distance detector is abnormal; when the distance detector is abnormal, according to the geomagnetic value, it is judged whether there is a car on the corresponding parking space ; when the distance detector is normal, judge whether there is a car on the corresponding parking space according to the distance information; that is, when the distance detector is abnormal, the vehicle detection result of the geomagnetic vehicle detector shall prevail, when the When the distance detector is normal, the vehicle detection result of the distance detector shall prevail. The method can improve the accuracy rate of vehicle presence detection, effectively avoid missed detection and false detection, and thus prevent users from evading parking fees.

Description

technical field [0001] The invention relates to the technical field of parking space management, in particular to a vehicle presence detection method and system. Background technique [0002] With the development of the economy and the improvement of people's living standards, cars are getting closer and closer to people's lives, and more and more people choose to go out by self-driving cars, resulting in shortage of public parking space resources and difficult parking problems. The problem of parking management can be effectively solved by informing the vehicle owner or the parking space management personnel in advance through the presence detection of the vehicle. At present, the traditional vehicle presence detection scheme only relies on one method to detect. For example, only relying on the installation of a geomagnetic detection module in the middle of the parking space, it can detect whether there is a vehicle in the parking space by detecting the change of the magne...
