Abstract

The invention provides a parking spot state detection method and device. The method comprises the steps that current standard background magnetic field data are confirmed, by collecting current magnetic field data, history magnetic field data and the current standard background magnetic field data in real time, current background magnetic field data are confirmed, by means of the disturbance state of the current magnetic field data and the departure degree of the current magnetic field data and the current background magnetic field data, first state information is confirmed, when the first state information is that a parking spot has no car or a car is driving into the parking spot, the parking spot which has no car at present is confirmed, and when the first state information is that a parking spot has the car or the car is driving in the parking spot, the parking spot which has the car at present is confirmed. The first state information is confirmed according to the current magnetic field data and the current background magnetic field data, a chain misjudgment caused by an accidental misjudgement cannot occur, and the first state information is rich due to the fact that the first state information has information that the parking spot has no car, the parking spot has the car, the car is driving into the parking spot and the car is leaving the parking spot, and the parking spot state confirmed by the first state information is accurate.

Description

Technical field [0001] The invention relates to the technical field of parking space state detection, in particular to a parking space state detection method and device. Background technique [0002] With the development of sensor technology and network technology, sensor networks have gradually matured and been widely used in various aspects. Using geomagnetic changes to detect the status of vehicles on parking spaces is an important direction of parking detection applications in recent years. Compared with traditional ultrasonic and video detection methods, it has relatively low cost, easier installation, higher recognition, strong adaptability, and all-weather work. Etc. [0003] In the prior art, a method for detecting parking spaces based on geomagnetic signals determines whether there is a car parked in a parking space by analyzing changes in the geomagnetic field and the stability level. Specifically, collect a set of geomagnetic signals from the detected parking space to ...
