Embodiment Construction

[0025] The present invention detects the geomagnetic data of the parking space through the geomagnetic parking space detector, such as the geomagnetic induction intensity of the parking space, and determines the change of the geomagnetic induction intensity of the parking space according to the collected geomagnetic induction intensity of the parking space, and then judges the state of the parking space, that is, the state of having a car , In and out of the car state, no car state.

[0026] Specifically, in the present invention, a geomagnetic parking space detector can be installed in the parking space to detect and collect the geomagnetic induction intensity within a certain range. Further, the geomagnetic parking space detector can be placed under the parking space, for example, buried directly under the parking space. The geomagnetic parking space detector can collect geomagnetic induction data in two directions, including: the geomagnetic induction in the direction of th...

Abstract

The invention discloses a double-axis geomagnetic stall detecting method and a double-axis geomagnetic stall detecting device. The method comprises the following steps: reading the current geomagnetic flux density data in two directions in real time, wherein one direction refers to a direction that a vehicle enters a garage, and the other direction is perpendicular to the ground downwards; acquiring the fluctuating value of a data sequence corresponding to each direction based on the geomagnetic flux density data which are read in the two directions in real time, wherein the data sequence consists of multiple geomagnetic flux density data; judging whether a vehicle is parked in a stall according to the fluctuating value of the data sequence corresponding to each direction and preset judgment threshold values. The method disclosed by the invention has the advantages of easiness in technical realization, low cost and high detection accuracy.

Description

technical field [0001] The invention relates to the technical field of parking space detection, in particular to a dual-axis geomagnetic parking space detection method and device. Background technique [0002] Since the number of cars has increased significantly in the past few decades, it takes a lot of time for people to find parking spaces. In order to facilitate people to find parking spaces, and also to manage parking spaces in the parking lot management personnel, the automatic parking detection system It gradually started to be used in large parking lots. [0003] There are various existing parking space detection methods, but there are technical deficiencies or cost pressures. For example, traditional parking space detectors are used to detect the presence of vehicles through inductive coils buried under the ground. However, this method has disadvantages The reason is that the volume of the coil is large, the damage to the ground is serious, the service life of the ...
