Problems solved by technology

Its detection accuracy is high, but the disadvantage is that the installation of the transmitter and receiver requires a bracket for each parking space, and the power consumption requires wired power supply, and the wiring is more complicated, resulting in high cost and inconvenient installation and use in outdoor environments
The accuracy of the video detection method is limited, the angle of the installation position is high, it is easily affected by weather factors, and the equipment cost is high, so it is rarely used on a large scale
Moreover, the existing parking detection mainly uses the occupied time of the parking space as the basis for billing, without further analysis and research

Embodiment Construction

[0041] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0042] A geomagnetic sensor parking monitoring method, comprising the steps of:

[0043] a. Sampling the space magnetic field of the parking space at a certain frequency through the geomagnetic sensor; better results can be obtained by sampling the space magnetic field at a higher frequency (such as 128Hz).

[0044] b. Comparing the collected spatial magnetic field value with the pre-acquired spatial magnetic field value of the parking space in the case of an empty parking space, the following discrimination results are obtained: when the absolute value of the difference between the two exceeds a certain threshold, it is determined that there is a vehicle in the parking space, and the discrimination result is "true"; when the absolute value of the difference between the two is less tha...

Abstract

The invention discloses a geomagnetic sensor parking monitoring method, comprising the following steps of a, sampling a parking space magnetic field by a geomagnetic sensor with a certain frequency; b, comparing the sampling with a previously obtained space magnetic field value under the empty parking space condition to judge whether a vehicle is parked; c, periodically reporting sampling judging results of the time point as 0X25 data; d, reporting the data with two continuous different sampling judging results in real time as 0X23 data; e, firstly, dividing time into time periods continuously connected end to end according to the 0X25 data and judging whether an vehicle is parked according to the 0X25 data, secondly, if the 0X23 data are received in a certain time period, judging the parking space state of the time period as non-parking; f, generating a parking space occupying matrix; g, generating an effective parking matrix LD according to the length of the parking time. The geomagnetic sensor parking monitoring method realizes the real-detection on the parking condition of parking spaces, and a comprehensive parking condition changing rule is obtained.

Description

technical field [0001] The invention relates to the technical field of parking detection, in particular to a technology for automatically detecting the occupancy of parking spaces, and a geomagnetic sensor parking monitoring method for automatically statistically analyzing the parking conditions based on the technology. Background technique [0002] With the increase of the number of motor vehicles, the parking problem has become an urgent problem to be solved in urban traffic just like road congestion, and it is also a livelihood issue related to the daily life of the public. The government has introduced a series of policies such as franchising and adjustment of parking rates to manage parking in order to make parking more orderly and standardized. In order to improve management efficiency and implement parking policies, it is necessary to carry out refined management. In order to improve service levels, parking companies also need to grasp the precise use of parking space...
