The invention discloses a method and a device for detecting a parking state of a parking space. The method comprises the steps of: determining the parking state of the parking space in a last samplingperiod; acquiring the parking state and a magnetic field sampling value of the parking space in the last sampling period; determining whether a magnetic field in a current sampling period fluctuates;if so, determining a first parking state of the parking space in the current sampling period, and acquiring a second parking state detected by means of a micro-radar sensor after a preset time period; and determining a parking state of the parking space in the current sampling period according to the parking state the parking space in the last sampling period, the first parking state and the second parking state. The method and the device solve the problems that the detection precision of a single geomagnetic sensor is not high and the micro-radar sensor is difficult to integrate.
Description
technical field [0001] Embodiments of the present invention relate to the field of intelligent transportation, and in particular to a method and device for detecting a parking state of a parking space. Background technique [0002] Parking status detection of parking spaces is generally detected by geomagnetic sensors. Geomagnetic sensors judge whether there is a vehicle passing through by detecting voltage changes caused by changes in the magnetic field. The detection accuracy is not high due to the influence of parked vehicles. [0003] Since the battery module for the parking state detection device needs to be buried on the ground, the power of the battery module is limited. The power of the battery module is only enough for the normal operation of the geomagnetic sensor, and it is difficult to add other detection devices (such as micro-radar sensors) to the detection device. Contents of the invention [0004] Embodiments of the present invention provide a method and d...
