Embodiment Construction

[0032] The geomagnetic sensor generally judges whether there are wheels parked according to the geomagnetic changes in a certain direction. If a vehicle is parked in an adjacent parking space, it will also cause deviations in the geomagnetic induction results of the parking space, and different models have different effects on the geomagnetism when parking, sometimes even gaps. very big.

[0033] In order to solve the above problems, an embodiment of the present invention provides a method for detecting roadside parking spaces. Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0034] In order to describe the technical solutions provided by the embodiments of the present invention in more detail, firstly, the principles of geomagnetis...

Abstract

The invention provides a roadside parking space detection method and relates to the communication field. By using a current geomagnetic sensor detection parking space mode, a detection result is easy to generate a deviation because of an external influence so that accuracy is low. By using the method of the invention, the above problem can be solved. The method comprises the following steps: burying a geomagnetic sensor and a wireless communication amplification module in a center position of a parking space, and collecting vertical geomagnetic data and horizontal geomagnetic data of the parking space and RSSI data of the parking space, wherein the vertical geomagnetic data and the horizontal geomagnetic data are acquired by the geomagnetic sensor; the RSSI data is acquired by the wireless communication amplification module; the vertical geomagnetic data is the geomagnetic data which is vertical to a ground direction; the horizontal geomagnetic data is the geomagnetic data which is parallel to the ground direction; comparing the collected vertical geomagnetic data of the parking space with a preset stable vertical geomagnetic data value. A technical scheme provided in the invention is suitable for traffic management and accurate parking space detection is realized.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for detecting roadside parking spaces. Background technique [0002] With the continuous development of our country's economy, road congestion and parking difficulties have always plagued most cities in our country, especially those who own cars. [0003] The use of geomagnetic sensors for parking space detection is an emerging parking space detection method in recent years, and it is more and more popular among parking equipment suppliers and parking lots. The geomagnetic sensor mainly uses the influence of the address magnetic field when the vehicle passes to complete the vehicle detection. Compared with the traditional geomagnetic induction coil, ultrasonic parking space detector, video parking space detector, etc. There are advantages in the reliability and other aspects of the results, and it has become a very important vehicle detection device. [0004] The geomagnetic ...
