Roadside parking space detection device based on composite detection mechanism and detection method thereof

Abstract

The invention relates to a roadside parking space detection device based on a composite detection mechanism and a detection method thereof. The technical characteristic is that the roadside parking space detection device comprises a geomagnetic sensor, a vibration radar sensor, a parking space detection processor and a power supply management module. The detection method comprises the steps that the geomagnetic sensor detects geomagnetic field signals on a parking space in real time; the parking space detection processor judges whether magnetic field variation waveform is ideal waveform or not, if the magnetic field variation waveform is not the ideal waveform, starting the vibration radar detection mechanism; and the parking space detection processor determines a parking condition in the parking space according to a detection result of the vibration radar detection mechanism. According to the invention, the parking space detection device is provided with the vibration radar sensor, thereby realizing functions of organic combination, mutual support and mutual dependency of the geomagnetic sensor and the vibration radar sensor, not only solving a problem that geomagnetic parking space detection is inaccurate in extreme conditions, but also overcoming a problem that the vibration radar sensor is too high in power consumption.

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 based on a composite detection mechanism. 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 t...
