Problems solved by technology

[0004] In order to solve the problems of fewer parking spaces, high system cost, and large installation space required by existing parking space detection devices, the present invention proposes a laser-based scanning method that divides the fan-shaped scanning area into multiple parking space detection areas corresponding to different parking spaces. A multi-parking laser detection device that determines whether there are parked vehicles in the parking space detection area by detecting the connection and interruption of the laser scanning reflected light path

Embodiment Construction

[0044] figure 1 A schematic diagram of the laser scanning device. exist figure 1 Among them, the laser sensor 1 is fixed on the steering table 2, and can freely rotate around the steering table rotation axis 3 together with the steering table 2; the motor 4 drives the steering table 2 to rotate around the steering table through the coaxial transmission disc 5 fixed on its rotating shaft The shaft 3 rotates, and the steering table 2 can be rotated reciprocally through the forward and reverse control of the motor 4, so that the laser beam emitted by the laser sensor 1 performs a sectoral scan greater than 0 degrees and less than or equal to 360 degrees; the laser beam sectoral scan The area 10 corresponds to the scanning angle range of each parking space to be detected, and is divided into one or more parking space detection areas 11; the scanning angle of the laser beam emitted by the laser sensor 1 can be directly detected by the corner sensor 6 of the steering platform 2, I...

Abstract

Provided is a multi-stall laser detection device which is composed of a laser sensor, laser reflection devices, a scan steering device, a turning angle detection device and a control device. Laser beams emitted by the laser sensor are enabled to perform sector scanning in the air via the scan steering device; a sector scanning area is divided into multiple stall detection areas in advance, and each stall detection area is provided with a set of laser reflection device; the turning angle detection device is used for detecting the sector scanning angle of the laser beams, and the detection result is outputted to the control device; the scanned stall detection area in which the laser beams are positioned is confirmed by the control device according to the detection signal of the turning angle detection device, and existence of parking vehicles in the corresponding parking stalls of all the stall detection areas is comprehensively judged according to laser beam path reflection sensing signals emitted by the laser sensor and reflected by the laser reflection devices so that the effect and the objective of detecting multiple parking stalls in real time can be achieved.

Description

Technical field [0001] The invention relates to a parking space detection device, in particular to a multi-parking space laser detection device. Background technique [0002] At present, most of the parking space detection devices use ultrasonic detection, geomagnetic detection, and photoelectric detection, etc., which are characterized by a single parking space detection method in which one parking space is equipped with a set of detectors. Therefore, for a parking lot composed of multiple parking spaces , the cost of the detection device is relatively high, and the installation and maintenance of the detection device are also relatively inconvenient. For a video detector that can detect multiple parking spaces, the detection results are affected by factors such as the lighting environment in the parking lot and the interference of lights, the camera shooting angle, the installation height of the roof, and the buildings in the parking lot that obstruct the view. The number...
