Abstract

The present invention relates to a roadside parking space detection device and a detection method thereof. The roadside parking space detection device is characterized in that the device includes a geomagnetism sensor, a radar sensor, a parking space detection processor and a power source management module. The detection method includes the following steps that: the geomagnetism sensor detects geomagnetic field signals on a parking space and transmits geomagnetic field change waveforms to the parking space detection processor; the parking space detection processor judges whether the geomagnetic field change waveforms are ideal waveforms, if the geomagnetic field change waveforms are the ideal waveforms, the parking space detection processor determines a parking condition on the parking space according to a geomagnetic detection mechanism; if the geomagnetic field change waveforms are not the ideal waveforms, a radar detection mechanism is started; and the parking space detection processor determines the parking condition on the parking space according to the detection result of the radar detection mechanism.

Description

technical field [0001] The invention belongs to the technical field of geomagnetic parking space detection, in particular to a roadside parking space detection device and a detection method thereof. Background technique [0002] Using geomagnetic sensors to detect roadside parking spaces is a parking space detection method that has been widely used in recent years. Geomagnetic sensors mainly use the influence of vehicles on the earth's magnetic field to complete vehicle detection. Compared with traditional geomagnetic induction coils and video parking space detectors, they have advantages in many aspects such as detection accuracy, cost, construction strength, and reliability. , has become a very important vehicle detection device. However, there are many factors that cause geomagnetic changes, and the vehicle is only one of them. Even if the geomagnetic sensor detects a change in the earth's magnetic field, the change may not be caused by the vehicle stopping. For example...
