Abstract
Description
Technical Field
[0001] This utility model relates to the field of parking equipment technology, and in particular to a mechanical parking equipment and its vehicle weight limit detection system. Background Technology
[0002] Currently, more intelligent mechanical parking systems (such as vertical lifting parking systems, horizontal moving parking systems, aisle stacking parking systems, and robotic transport parking systems) typically include a conversion area, a working area, and a transporter. A conversion area gate is installed before the conversion area, and a vehicle weight detection device is located within the conversion area. When parking, the user drives the vehicle to the conversion area gate, which automatically opens. The user then drives the vehicle into the conversion area and parks it on the parking platform. The vehicle weight detection device checks the vehicle's weight, and if the weight meets the parking system's weight limit, the transporter moves the vehicle into the working area for storage.
[0003] However, if the vehicle's weight does not meet the weight limit, the user will be required to return to the transition area and drive the vehicle out of the transition area, and the vehicle will be prohibited from being parked in this parking facility. This reduces the efficiency of parking equipment in storing and retrieving vehicles and also results in a poor user experience. Utility Model Content

[0037] Figure 1 This is a schematic side view of a mechanical parking device according to an embodiment of the present invention, such as... Figure 1 As shown, and with reference Figures 2 to 3 This utility model provides a vehicle weight limit detection system 100 for mechanical parking equipment, including an image acquisition device 110 and a weight limit control device 120.
[0038] The image acquisition device 110 is located outside the transfer zone door 200 of the mechanical parking equipment 10. The image acquisition device 110 is configured to acquire image information of the vehicles to be stored outside the transfer zone door 200.
[0039] The weight limit control device 120 is electrically connected to the image acquisition device 110 and the conversion area door 200. The weight limit control device 120 is configured to obtain the vehicle model and curb weight of the vehicle to be stored based on the image information, and control the conversion area door 200 to be closed when the curb weight is greater than the weight limit threshold of the mechanical parking equipment 10.
[0040] The mechanical parking equipment 10 can be a vertical lifting parking equipment, a horizontal moving parking equipment, a lane stacking parking equipment, or a handling robot parking equipment, etc. The mechanical parking equipment 10 may include a conversion area 300, a work area 500, and a transporter / transport robot. The conversion area 300 and the work area 500 are typically relatively enclosed areas. The conversion area 300 is typically the area where, during vehicle storage and retrieval, the driver's driving state is switched to the parking equipment control state, or vice versa. The work area 500 is typically the area where the parking equipment operates and stores vehicles; drivers are not allowed to enter this area. The transporter / transport robot operates in the conversion area 300 and the work area 500 to transport vehicles parked in the conversion area 300 to the work area 500 and place them in designated parking spaces.
[0041] Mechanical parking equipment 10 is equipped with weight limits (e.g., 1.8 tons, 2 tons, 2.3 tons, etc.) to prohibit overweight vehicles from parking, thus preventing damage to the parking equipment. In related technologies, a vehicle weight measuring device is typically installed in the transition zone 300. After a driver enters the transition zone 300 and parks the vehicle, the weight measuring device measures the vehicle's weight. Only when the vehicle weight meets the parking equipment's weight limit will the next procedure be allowed, i.e., controlling the transporter / robot to deliver the vehicle to the work area 500 for storage. If the vehicle weight does not meet the weight limit, the driver is required to return to the transition zone 300 and drive the vehicle out of the transition zone 300, prohibiting the vehicle from being stored in this parking equipment. For vehicles that do not meet the weight limit, entering and exiting the transition zone 300 takes a considerable amount of time. This prevents normal vehicle storage and retrieval in the transition zone 300, increasing the waiting time for subsequent queuing users, resulting in a poor user experience and reducing the efficiency of the parking equipment. On the other hand, it wastes the time of drivers of vehicles that do not meet the weight limit requirements, resulting in a poor user experience.
[0042] In this embodiment, a transfer area door 200 is provided at the front of the transfer area 300. The transfer area door 200 opens when vehicles are being stored or retrieved to allow vehicles to enter or exit. At other times, the transfer area door 200 is normally kept closed to prevent unauthorized personnel, vehicles, pets, etc., from entering the transfer area 300. The transfer area door 200 can be driven by a motor, hydraulic system, or other means to achieve controlled opening and closing. In some embodiments, a work area door 400 may also be provided between the transfer area 300 and the work area 500. When the driver is in the transfer area 300, the work area door 400 is closed to prevent unauthorized personnel from entering the work area 500. When the driver leaves the transfer area 300, the work area door 400 is opened to allow the transporter / transportation machine to enter or exit the transfer area 300.
[0043] In this embodiment, an image acquisition device 110 is installed on the outside of the transfer area door 200. The image acquisition device 110 can acquire image information of vehicles waiting to be stored, driven to the front of the transfer area door 200, by means of taking pictures, recording videos, etc. For example, the image acquisition device 110 may include a license plate recognition device, a vehicle shape recognition device, etc. Both license plate recognition devices and vehicle shape recognition devices are relatively mature existing technologies. The license plate recognition device can identify the license plate number by taking a picture of the license plate of the vehicle to be stored. The vehicle shape recognition device can identify the vehicle model by taking a picture of the exterior image of the vehicle to be stored.
[0044] The weight limit control device 120 can be electrically connected to the image acquisition device 110 via wired or wireless means, and can also be electrically connected to the drive device of the transfer zone door 200 via wired means. The image acquisition device 110 can transmit image information, or information obtained from the image information (such as license plate number), to the weight limit control device 120.
[0045] The weight limit control device 120 may include a PLC, a microcontroller, a computer, etc., to obtain the vehicle model and curb weight of the vehicle to be stored after receiving information from the image acquisition device 110. For example, the weight limit control device 120 can connect to a public database of a traffic management department to retrieve the corresponding vehicle model and curb weight by querying the license plate number. The weight limit control device 120 can also connect to various commercial databases. Of course, the weight limit control device 120 can also build a local database. All of the above databases will record information about all vehicles, including license plate number, vehicle model, curb weight, wheelbase, etc.
[0046] After obtaining the curb weight of the vehicle to be stored, the weight control device 120 can determine whether the curb weight exceeds the weight limit threshold of the parking equipment. When the curb weight is less than or equal to the weight limit threshold, it can be preliminarily considered that the vehicle to be stored meets the weight limit requirements of the parking equipment, and the device will control the opening of the transfer area door 200 to allow the driver to drive the vehicle to be stored into the transfer area 300.
[0047] When the vehicle's curb weight exceeds the weight limit threshold, it can be confirmed that the vehicle does not meet the weight limit of the parking equipment. The system will then close the transition area door 200 if it is currently open, or close the door if it is already open, to prevent drivers from entering the transition area 300. This allows drivers of overweight vehicles to drive their vehicles directly to another parking space without wasting time driving into the transition area 300, where they must confirm the vehicle is overweight before driving it out. This saves time for drivers of overweight vehicles, improving their user experience. Furthermore, it does not disrupt normal vehicle storage and retrieval in the transition area 300, reducing waiting time for other users and improving the overall efficiency of the parking equipment.
[0048] In some embodiments of the vehicle weight limit detection system of this utility model, such as Figure 1 As shown, the vehicle weight detection system 100 also includes a vehicle weight measuring device 130. The vehicle weight measuring device 130 is located within the transition area 300 of the mechanical parking equipment 10 and is electrically connected to the weight control device 120. The vehicle weight measuring device 130 is configured to measure the actual weight of the vehicle to be parked entering the transition area 300. The weight control device 120 is further configured to open the transition area door 200 or control the transition area door 200 to be in an open state when the actual weight exceeds the weight limit threshold.
[0049] In this embodiment, the vehicle weight measuring device 130 is used to measure the actual weight of the vehicle to be stored and to ultimately determine whether the weight limit requirement of the parking equipment is met based on the actual weight. It should be understood that storing heavy items in a vehicle or modifying the vehicle can cause the actual weight of the vehicle to be stored to be much greater than its curb weight. By measuring the actual weight, the situation can be avoided where the curb weight meets the weight limit requirement, but the actual weight does not, thus improving the safety of the parking equipment.
[0050] In this embodiment, after the vehicle weight measuring device 130 detects that the actual weight is much greater than the curb weight, it will transmit the information to the weight limit control device 120. The weight limit control device 120 will then control the opening of the transition zone door 200 to allow the driver to enter the transition zone 300 and drive the overweight vehicle out of the transition zone 300 in a timely manner.
[0051] On the other hand, in actual use, there may be situations where the image acquisition device 110 fails to acquire image information, or the weight control device 120 fails to identify the curb weight of the vehicle to be stored. In this case, the weight control device 120 will directly open the conversion area door 200 to allow the vehicle to be stored to enter the conversion area 300. After the vehicle weight measuring device 130 measures the actual weight, it will finally determine whether the weight limit requirement of the parking equipment is met.
[0052] In some embodiments of the vehicle weight limit detection system of this utility model, such as Figure 1 As shown, the mechanical parking equipment 10 is equipped with a work area door 400 for separating the transition area 300 and the work area 500 of the mechanical parking equipment 10. The weight limit control device 120 is electrically connected to the work area door 400.
[0053] The weight limit control device 120 is also configured to keep the work area door 400 closed when the actual weight exceeds the weight limit threshold.
[0054] Work area door 400 is used to separate transition area 300 and work area 500, preventing unrelated personnel, pets, etc., from entering work area 500 through transition area 300. Work area door 400 can be opened and closed by means of motor, hydraulics, etc. When there are personnel in transition area 300, work area door 400 will be closed. When a transporter / transporting machine enters or exits, work area door 400 will be opened.
[0055] In this embodiment, when the actual weight exceeds the weight limit threshold, the work area door 400 is kept closed to further prevent overweight vehicles from entering the work area 500 and causing safety hazards.
[0056] In some embodiments of the vehicle weight limit detection system of this utility model, such as Figure 1 As shown, the vehicle weight measuring device 130 includes a parking platform 131 and multiple vehicle weight sensors 133.
[0057] After the vehicles enter the conversion area 300, they are parked on the parking platform 131, which has multiple support columns 132 at its bottom. A vehicle weight sensor 133 is installed between each support column 132 and the ground 310 of the conversion area. Each vehicle weight sensor 133 is electrically connected to the weight limit control device 120.
[0058] In this embodiment, the parking platform 131 can be a vehicle-carrying platform 131, a comb-type parking platform 131, etc., and there is no limitation. For example, the parking platform 131 can have four support columns 132 at its four corners, and each support column 132 is equipped with a vehicle weight sensor 133. After the vehicle to be parked is placed on the parking platform 131, each vehicle weight sensor 133 measures the weight, and the total weight is then calculated to obtain the actual weight of the vehicle to be parked.
[0059] In some embodiments of the vehicle weight limit detection system of this utility model, such as Figure 1 As shown, the work area door 400 is equipped with a first drive motor 410, and the weight limit control device 120 is electrically connected to the first drive motor 410.
[0060] The weight limit control device 120 is also configured to control the first drive motor 410 to open the work area door 400 when the actual weight is less than or equal to the weight limit threshold.
[0061] The work area door 400 can be a horizontal sliding door, a vertical lifting door, etc., and there are no restrictions here. The work area door 400 can also be equipped with a running guide rail, an opening limit switch, a closing limit switch, etc. The weight limit control device 120 can control the operation of the first drive motor 410, and determine whether the work area door 400 is fully open or closed through the opening limit switch and the closing limit switch.
[0062] In some embodiments of the vehicle weight limit detection system of this utility model, such as Figure 1 As shown, the vehicle weight limit detection system 100 also includes a first display device 141. The first display device 141 is disposed in the conversion area 300 and is electrically connected to the vehicle weight measuring device 130 and / or the weight limit control device 120. The first display device 141 is configured to display an alarm image regarding overweight when the actual weight exceeds the weight limit threshold.
[0063] The first display device 141 can be a display screen, an LED array, etc. When the actual weight exceeds the weight limit threshold, it can display text information such as "Overweight" or "Please Exit", or graphic symbols related to overweight, prompting the driver to drive the vehicle out of the transition zone 300.
[0064] In some embodiments of the vehicle weight limit detection system of this utility model, such as Figure 1 As shown, the vehicle weight limit detection system 100 also includes a first voice device 142. The first voice device 142 is located in the conversion area 300 and is electrically connected to the vehicle weight measuring device 130 and / or the weight limit control device 120. The first voice device 142 is configured to issue an overweight alarm sound when the actual weight exceeds the weight limit threshold.
[0065] The first display device 141 may be a buzzer, speaker, etc. When the actual weight exceeds the weight limit threshold, it may emit an alarm sound or / or issue a voice message such as "overweight" or "please exit" to prompt the driver to drive the vehicle out of the transition zone 300.
[0066] In some embodiments of the vehicle weight limit detection system of this utility model, such as Figure 2 As shown, the vehicle weight limit detection system 100 also includes a second display device 151.

The second display device 151 is configured to display an overweight alarm image when the curb weight exceeds the weight limit threshold.
[0067] The second display device 151 can be a human-machine interface for parking equipment. When the curb weight exceeds the weight limit threshold, it can display text information such as "overweight" or "no entry", or graphic symbols related to overweight, to remind the driver that the vehicle is overweight and prohibit the vehicle from entering the transition area 300.
[0068] In some embodiments of the vehicle weight limit detection system of this utility model, such as Figure 2 As shown, the vehicle weight limit detection system 100 also includes a second voice device 152. The second display device 151 is located outside the transition zone door 200 and is electrically connected to the weight limit control device 120. The second voice device 152 is configured to issue an overweight alarm sound when the curb weight exceeds the weight limit threshold.
[0069] The second display device 151 may be a buzzer, speaker, etc. When the curb weight exceeds the weight limit threshold, an alarm sound or other sound should be emitted, and / or voice prompts such as "overweight" or "no entry" should be emitted to remind the driver that the vehicle is overweight and prohibit the vehicle from entering the transition area 300.
[0070] In some embodiments of the vehicle weight limit detection system of this utility model, such as Figure 2 As shown, the image acquisition device 110 includes a license plate recognition device 111, which is configured to acquire images of the license plates of the vehicles to be stored and identify the license plate numbers. The weight limit control device 120 is configured to query the established vehicle information database based on the license plate number to obtain the vehicle model corresponding to the license plate number and obtain the corresponding curb weight.
[0071] The license plate recognition device 111 is a relatively mature technology with high recognition accuracy and low cost. It can quickly and accurately identify the license plate number of the vehicle to be stored, so that the weight limit control device 120 can obtain the vehicle model and curb weight of the vehicle to be stored.
[0072] In this embodiment, the established vehicle information database can be a public database of the traffic management department, a commercial database, or a locally built database.
