Description

Technical Field

[0001] The invention relates to a parking system for a three-dimensional garage, in particular to a multifunctional parking system for a parking hall. Background Art

[0002] With the acceleration of urban construction and the sharp increase in the number of cars, stereo garages have become an inevitable trend in the current parking reform, especially in large cities where every inch of land is valuable. The use of stereo parking lots is the inevitable way to solve the parking problem. With the continuous advancement of parking equipment technology and the popularization of smart parking concepts, more stringent requirements are put forward for the parking methods and parking efficiency of stereo garages. In view of the relatively simple parking hall function of existing stereo garages, the product level of the parking hall is improved, the equipment function is increased, and a multifunctional parking system with high intelligence, safe and fast storage and retrieval of cars is designed, which is applied to various types of stereo garages.

[0003] In order to detect the size and position of vehicles in the existing mechanical parking equipment, multiple sets of light curtains or photoelectric sensors are required to detect the size and position of vehicles. The installation is complicated and the detection accuracy is not high. For some vehicles with luggage racks and antennas, there are cases of misdetection or missed detection, which may cause certain parking safety problems. Therefore, there is an urgent need for a parking hall vehicle size detection method that can effectively improve the vehicle detection efficiency of the stereo garage and ensure parking safety. Summary of the invention

[0004] The main purpose of the present invention is to provide a multifunctional parking system in a parking hall, which uses visual cameras and laser radars to replace the previous light curtains and photoelectric sensors to complete vehicle information recognition and vehicle size detection during the vehicle entry process, thereby improving the accuracy of vehicle size detection. At the same time, through real-time detection of the system, vehicle deviation or over-limit detection can also be achieved, providing more accurate guidance and improving the parking experience.

[0005] In order to achieve the above object, the present invention provides a multifunctional parking system for a parking hall, comprising: The parking space in the parking hall is equipped with a circular parking area. A laser radar is installed above the door in the parking hall, and a visual camera is installed above the wall corresponding to the door. The laser radar, circular parking area, visual camera and door are located on the same central axis. A parking guidance device, wherein the parking guidance device is arranged directly below the visual camera; The upper server includes a data receiving module, a storage module, a distribution module, a size calculation module and a graphics processing module. The laser radar and the visual camera are electrically connected to the data receiving module respectively. After receiving the data, the data receiving module stores the data in the storage module. The storage module sends the stored data to the distribution module. The distribution module organizes the data and sends the data information of the laser radar to the size calculation module, and sends the picture information of the visual camera to the graphics processing module. After processing and analysis by the graphics processing module, it is determined whether the vehicle finally drives out of the circular parking area, and the vehicle's driving direction is prompted according to the determination result. The graphics processing module displays the indication of the vehicle's driving direction through the parking guidance device.

[0006] Preferably, the upper server also includes a human-computer interaction device, which is arranged outside the vehicle hall, and the driver and passengers interact with the upper server through the human-computer interaction device.

[0007] Further preferably, the multifunctional parking system in the vehicle hall also includes a lower-level PLC controller, and the human-computer interaction device is electrically connected to an action execution module in the lower-level PLC controller, and the action execution module is used to control the opening and closing of the door of the vehicle hall.

[0008] More preferably, a weight detection device is provided under the circular parking area, and the weight detection device is electrically connected to the lower PLC device. The weight detection device sends the vehicle weight data to the storage module, and the storage module stores the detection result and then sends the vehicle weight data to the distribution module. The distribution module sends the vehicle weight data to the analysis module, and the analysis module analyzes the vehicle weight data. If the parking requirements are met, no information is sent to the parking guidance device. If the parking requirements are not met, information is sent to the parking guidance device, and the parking guidance device displays weight failure information.

[0009] More preferably, the lower-level PLC controller also includes a safety detection device, which is used to detect the surrounding area of ​​the vehicle and upload the detection result to the storage module of the upper-level server. The storage module stores the detection result and then sends the detection result to the distribution module. The distribution module sends the detection result to the analysis module, which analyzes the detection result. If the parking requirements are met, no information is sent to the parking guidance device. If the parking requirements are not met, information is sent to the parking guidance device. After receiving the information, the parking guidance device displays safety failure information.

[0010] More preferably, a plurality of sampling groups are provided at the edge of the circular parking area, and the sampling groups are symmetrically arranged with respect to the central axis of the circular parking area, each sampling group includes two sampling points, and the visual camera can capture all sampling points when the vehicle does not enter the circular parking area.

[0011] More preferably, when a vehicle passes through a circular parking area, the visual camera collects images of the sampling points. After receiving the images, the graphics processing module detects whether the number of sampling points on both sides of the central axis blocked by the vehicle is the same. If they are the same, no information is sent to the parking guidance device. If they are different, information is sent to the parking guidance device to instruct the vehicle to move in the corresponding direction.

[0012] More preferably, the image processing module analyzes the sampling groups in the same column in real time, and draws lines between the sampling points in the same column of the same group and the vertices located on the central axis of the circular parking area to form a triangular area; when the sampling points in the same column cannot form a triangular area, if only one vertex is left, no information is sent to the parking guidance device; if only one vertex and one sampling point are left, information is sent to the parking guidance device to guide the vehicle to move in the corresponding direction.

[0013] The beneficial effects of the present invention are: 1. Accurate positioning and guidance: The laser radar above the door in the parking hall and the visual camera above the wall corresponding to the door are located on the same central axis as the circular parking area and the door. Combined with the size calculation module and graphics processing module of the upper server, they can accurately obtain vehicle information and determine whether the vehicle will eventually exit the circular parking area. The parking guidance device prompts the vehicle's driving direction, helps the vehicle to park and exit accurately, and improves parking accuracy and efficiency.

[0014] 2. Automatically control the hall door: The human-machine interaction device is electrically connected to the action execution module in the lower PLC controller, which can automatically control the opening and closing of the car hall door to achieve automated management without manual operation, saving manpower and improving the convenience and safety of the car hall.

[0015] 3. Weight detection ensures safety: The weight detection device under the circular parking area can detect the weight of the vehicle. After analysis by the analysis module, it is determined whether it meets the parking requirements. If it does not meet the requirements, the parking guidance device will display the weight failure information, which can prevent overweight vehicles from entering the parking area and causing damage to the parking hall facilities, thereby ensuring the safety of the parking hall and the service life of the facilities.

[0016] 4. Safety testing to prevent risks: The safety detection device of the lower-level PLC controller detects the entire vehicle, and the analysis module determines whether it meets the parking requirements based on the detection results. If not, the parking guidance device displays a safety failure message, which can detect safety hazards in the vehicle in advance, prevent vehicles with safety issues from entering the parking area, and reduce potential risks.

[0017] 5. Symmetrical sampling and precise parking: Multiple sampling groups are set at the edge of the circular parking area, which are arranged symmetrically with respect to the central axis. The visual camera cooperates with the graphics processing module to determine whether the vehicle is parked in a suitable position by detecting the number of sampling points on both sides of the central axis blocked by the vehicle. If the position is inappropriate, the vehicle is guided to the corresponding direction, which helps to park the vehicle accurately and make full use of the parking area space.

[0018] 6. Real-time analysis and optimization of parking: The image processing module analyzes the sampling groups in the same column in real time, and determines the vehicle position based on the triangular area formed by the sampling points and the vertices of the central axis. If the position is unreasonable, the vehicle is guided by the parking guidance device, which further improves the accuracy and efficiency of parking and optimizes the parking process.
