Parking space detection system and method based on double parking detectors

Abstract

The invention relates to a parking space detection system and method based on double parking detectors. The parking space detection system based on the double parking detectors is mainly characterized by comprising a parking space detection server, a wireless parking space detection network and the parking space detectors, the parking space detection server is connected with the parking space detectors through the wireless parking space detection network, and each of two sides, close to side lines of each parking space, is provided with one parking space detector. The parking space detection method includes the steps: using the two parking space detectors, on the side lines of each parking space, for detection; judging the state of the parking space is unchanged when detection values, of the two parking space detectors on the side lines of one parking space, hop within different time; using a matching detection method for the detection of the parking space when the detection values, of the two parking space detectors on the side lines of one parking space, hop at the same time. The parking space detection system and method based on the double parking detectors is reasonable in design and capable of effectively solving the problem of misjudgment due to vehicle magnetic field effect of the neighboring parking spaces which are arranged in a parallel mode, and accordingly detection precision is improved.

Description

technical field [0001] The invention belongs to the technical field of parking space detection, in particular to a parking space detection system and method based on double parking space detectors. Background technique [0002] At present, the detection method of the parking spaces in the roadside parking lot is: each parking space is detected by a parking space detector, and the parking space detector is buried on the vertical line of the parking space along the parking space arrangement direction. Since the radiation radius of the vehicle magnetic field is equal in the length direction and the width direction, generally within 2.5 meters outside the vehicle boundary, the radius in the length direction of the parking space must be greater than the radius in the width direction. When parking, the influence of its magnetic field on the center point of the adjacent parking space is much smaller than that of the magnetic field on the center point of the adjacent parking space w...

Problems solved by technology

Since the radiation radius of the vehicle magnetic field is equal in the length direction and the width direction, generally within 2.5 meters outside the vehicle boundary, the radius in the length direction of the parking space must be greater than the radius in the width direction. When parking, the influence of the magnetic field on the center point of the adjacent parking space is much smaller than that of the magnetic field on the center point of the adjacent parking space when the vehicles are parked side by side. Therefore, the above technical solution is only applicable to the serial parking method in which the vehicles are connected end to end.

For the way of parking vehicles side by side, that is, when the vehicles are not connected end to end but left and right, since the width of the general parking space is less than 2.5 meters, the magnetic field from the left and right adjacent spaces will cover most of the width of the parking space. Installing a parking space detector will be affected by the magnetic field of the adjacent space, resulting in misjudgment
