Embodiment 1

[0027] see figure 1 , a parking space state monitoring method based on the geomagnetic field provided by the embodiment of the present application, the method includes the following steps S101 to S105.

[0028] Step S101, obtaining the characteristic geomagnetic field strength at different time points at the parking space between the end of the last judgment on the status of the parking space and the current moment; wherein, each characteristic geomagnetic field strength includes a first magnetic field strength along the vertical direction and a first magnetic field strength along the parking space The second magnetic field strength in the longitudinal direction.

[0029] When the vehicle gradually enters and parks in the parking space, or the vehicle drives away from the parking space, the vehicle will gradually affect the strength of the geomagnetic field at the surface of the parking space, causing a large change in the strength of the geomagnetic field. And when the vehic...

Abstract

The present application relates to the technical field of parking space monitoring, in particular to a method and device for monitoring the status of parking spaces based on the geomagnetic field. The method includes: obtaining the characteristic geomagnetic field strength at different time points at the parking space between the end of the last judgment of the state of the parking space and the current moment; removing the interference data in the characteristic geomagnetic field strength; respectively using the first magnetic field in the characteristic geomagnetic field strength Intensity and the second magnetic field strength are abscissa and ordinate, according to the acquisition sequence of the characteristic geomagnetic field strength, determine the distance between every two adjacent described characteristic geomagnetic field strengths; The sum of the distances between the characteristic geomagnetic field strengths is used to obtain the characteristic parameters; according to the characteristic parameters and the last parking space state, the current parking space state is determined. The method and device have simple monitoring process, low monitoring cost and wide application prospects.

Description

technical field [0001] The present application relates to the technical field of parking space monitoring, in particular to a method and device for monitoring the status of parking spaces based on the geomagnetic field. Background technique [0002] In recent years, with the continuous improvement of the national economic level, the large increase and widespread use of automobiles has caused the number of parking spaces to increase sharply thereupon. Whether it is a private parking space or a public parking space, such as a parking lot, in order to facilitate the supervision and management of the parking space, the state of the parking space, that is, whether there are vehicles parked, may be monitored. [0003] At present, a commonly used method for monitoring the state of a parking space based on the geomagnetic field is carried out by means of a geomagnetic field monitoring device and an ultrasonic monitoring device at the same time. Specifically, both the geomagnetic fi...
