Embodiment Construction

[0025] Embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0026] A parking charging method based on the double-stable value of the geomagnetic platform is realized by using the calculation method of the geomagnetic variation of the double-stable value of the geomagnetic platform, which is obviously different from the traditional calculation method based on the zero-point geomagnetic deviation value.

[0027] The traditional calculation method based on the zero-point geomagnetic deviation value is as follows: figure 2 As shown, there are 3 curves on the parking space 300301, namely the X-axis curve, the Y-axis curve and the Z-axis curve. The 1-1 dashed line in the figure is the curve without zero point drift, and X0, Y0, and Z0 are the 1-1 zero point dashed line The initial value of the triaxial geomagnetic field on . Since there is no zero point drift in 1-1, it calculates the geomagnetic deviation ...

Abstract

The present invention relates to a parking tolling method based on a double stable value of a geomagnetic platform. Its technical characteristics include the following steps: after the geomagnetic changes tend to be stable, the stable value of the current time period is used as a geomagnetic platform, and the previous time period's The stable value is regarded as a geomagnetic platform; the geomagnetic platform whose change value exceeds the threshold is regarded as an effective geomagnetic platform; The changing cut-off time is used as the cut-off time for parking billing; the server automatically charges according to the parking duration and combined with the vehicle identity. The present invention eliminates the zero-point calibration step from the traditional geomagnetic inspection method, and can also achieve the effect of accurate billing; effectively avoids the strict restriction of calibration time and calibration environment caused by manual zero-point calibration, and manual calibration is labor-intensive. time-consuming problem.

Description

technical field [0001] The invention belongs to the technical field of parking lot charging, in particular to a parking charging method based on a double stable value of a geomagnetic platform. Background technique [0002] Using the geomagnetic parking space detector to detect the change of the parking space state and automatically calculate the parking time, and then combine various identification methods to automatically charge the server background is an efficient and simple parking charging method that is currently being respected. However, there is a bottleneck problem in the above method: the zero point drift problem of geomagnetic detection. The so-called geomagnetic detection zero point drift concept (temperature drift) can be described as: the zero point of the same geomagnetic meter changes with time and seasons. [0003] In order to overcome the problem of geomagnetic zero point drift, the zero point recalibration is usually carried out manually, that is, under ...
