Description
Technical Field
[0001] This utility model relates to the field of parking garage technology, and in particular to an intelligent parking garage based on geomagnetic sensing. Background Technology
[0002] With rapid urbanization, the number of cars in cities has exploded. According to statistics, in the past decade, the number of cars in many large cities has increased by more than 200%, which has led to a sharp rise in parking demand, making parking a critical issue that urgently needs to be addressed in urban transportation systems.
[0003] Currently, traditional parking garages widely adopt a license plate scanning system at entrances and exits for time-based billing, along with a one-vehicle-one-gate release system. Compared to earlier manual management, this method improves management efficiency to some extent, as it can automatically recognize license plates and accurately record vehicle entry and exit times to calculate parking fees.
[0004] However, the drawbacks of this model become glaringly apparent during peak hours or special events. For example, during weekday morning and evening rush hours, a large number of vehicles enter and exit parking garages, requiring license plate scanning equipment to identify and process data for each vehicle. If network fluctuations, equipment malfunctions, or license plates become difficult to recognize due to dirt or wear, waiting times at entrances and exits will significantly increase. In some busy commercial center parking garages, peak-hour waiting times can even exceed 30 minutes. A large number of vehicles queuing at entrances and exits for license plate scanning, payment, and barrier lifting can easily cause severe congestion. This congestion not only severely affects the normal flow of vehicles within the parking garage but also impacts surrounding roads, creating traffic bottlenecks, exacerbating overall urban traffic congestion, and increasing travel time costs for citizens.

[0018] (III) Beneficial Effects
[0019] The beneficial effects of this utility model are:
[0020] This invention provides an intelligent parking garage based on geomagnetic sensing. By embedding geomagnetic sensors at the front and rear of the parking spaces, it accurately detects whether a vehicle has entered or left a parking space using changes in the geomagnetic field, providing a reliable data foundation for parking garage management. When a vehicle parks, the geomagnetic sensor transmits the detected vehicle status information to the controller in real time.

Detailed Implementation
[0028] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.
[0029] Example 1:
[0030] like Figures 1-3 As shown, this embodiment provides an intelligent parking garage based on geomagnetic sensing, including a parking space 1, a parking locking device 2, a lifting drive 3, a charging pile 4, a controller, and two geomagnetic sensors 5. A blind hole is opened in the middle of the parking space 1, and the lifting drive 3 is set in the blind hole. The parking locking device 2 is fixed to the top of the lifting drive 3 so that the lifting drive 3 can drive the parking locking device 2 to rise closer to the vehicle chassis or lower away from the vehicle chassis. The two geomagnetic sensors 5 are respectively buried at the front and rear of the vehicle corresponding to the parking space 1. The lifting drive 3, the parking locking device 2, and the geomagnetic sensors 5 are connected to the controller, which is set in the charging pile 4. The charging pile 4 is set on one side of the parking space 1, and a billing display screen 41 and a payment window 42 connected to the controller are provided on the charging pile 4.
[0031] Specifically, by embedding geomagnetic sensors 5 at the front and rear of vehicles in parking space 1, changes in geomagnetic fields are used to accurately detect whether a vehicle has entered or left the parking space, providing a reliable data foundation for parking garage management. When a vehicle enters the parking space, the geomagnetic sensors 5 transmit the detected vehicle status information to the controller in real time. The controller then activates the lifting drive 3, which drives the parking locking device 2 to rise rapidly and approach the vehicle chassis. The controller then activates the parking locking device 2, which adheres to the vehicle chassis to lock the vehicle. Parking time then begins, and the parking time and hourly parking fee are displayed on the billing display screen 41 on the charging pile 4, allowing the driver to clearly understand the billing details. The charging pile 4 located on one side of parking space 1 provides convenient charging conditions for new energy vehicles. When a new energy vehicle parks in a parking space equipped with a charging pile 4, the driver can directly begin charging. The payment window 42 on the charging pile 4 provides a convenient payment method for the driver. Once charging is complete or parking is finished, vehicle owners can directly scan a QR code to pay at the payment window 42 on charging station 4, significantly shortening payment time, improving vehicle exit efficiency, and effectively alleviating congestion at parking garage entrances and exits. Compared to existing technologies, this optimizes the parking fee calculation and payment process. For owners of new energy vehicles, charging and payment are completed in the same location, making it more efficient and convenient, significantly improving vehicle flow speed, effectively alleviating congestion at parking garage entrances and exits, and improving overall parking efficiency and user experience.
[0032] Furthermore, such as Figure 4 As shown, the parking locking device 2 includes a protective layer 21, a buffer layer 22, and a magnetic layer 23; the protective layer 21, buffer layer 22, and magnetic layer 23 are arranged sequentially from top to bottom, with the magnetic layer 23 fixed to the top of the lifting drive 3. The uppermost protective layer 21 of the parking locking device 2 can effectively resist external physical impacts and wear. During vehicle parking, the protective layer 21 can prevent the parking locking device 2 from being damaged due to accidental collisions with the vehicle chassis or other objects, extending the device's service life, ensuring its long-term stable operation, and maintaining the reliability of the parking locking function. The middle buffer layer 22 can act as a buffer and shock absorber when the parking locking device 2 rises and contacts the vehicle chassis. It can reduce the impact force between the vehicle and the device, avoid scratching or damaging the vehicle chassis due to rigid contact, and also reduce the risk of damage to the parking locking device 2 itself due to impact, improving the safety and stability during vehicle parking. The bottom magnetic layer 23 is fixed to the top of the lifting drive 3. When the magnetic layer 23 is energized and generates magnetic force, it can attract the metal parts of the vehicle chassis, further enhancing the fixing effect of the parking lock device 2 on the vehicle, preventing the vehicle from shifting due to vibration, external force and other factors during parking, and improving the stability of the vehicle parking.
[0033] Furthermore, such as Figure 4 and Figure 5As shown, the magnetic layer 23 includes a magnetic core assembly and an excitation coil 24; the excitation coil 24 surrounds the magnetic core assembly. When current passes through the excitation coil 24, a magnetic field is generated, and the magnetic core assembly is magnetized under the action of the magnetic field, enhancing the overall magnetic field strength. This design can more effectively attract metal parts of the vehicle chassis, improve the attraction force of the parking lock device 2 to the vehicle, and ensure that the vehicle remains stable during parking. Specifically, the magnetic core assembly includes a first magnetic core 25, a second magnetic core 26, and a third magnetic core 27; the second magnetic core 26 is arranged around the first magnetic core 25, and the third magnetic core 27 is arranged around the second magnetic core 26; insulating material is filled between the first magnetic core 25 and the second magnetic core 26, and insulating material is filled between the second magnetic core 26 and the third magnetic core 27. The insulating material prevents current interference between the layers of magnetic cores, making the magnetic field generated by each layer of magnetic cores relatively independent and stable. This structure can increase the layering and uniformity of the magnetic field, improve the attraction effect of the magnetic layer 23 to the vehicle chassis, and further enhance the fixing ability of the parking lock device 2. The arrangement of different layers of magnetic cores allows the magnetic field to be effectively utilized in different areas, enabling more precise attraction to metal parts in different locations on the vehicle chassis. This avoids waste and ineffective distribution of the magnetic field, improves the utilization efficiency of the magnetic field, and reduces energy consumption while ensuring the locking effect.
[0034] Furthermore, in this embodiment, the first magnetic core 25 is a solid soft magnetic alloy core. As the first magnetic core 25, the solid soft magnetic alloy core has good magnetic permeability and can stably conduct and enhance the magnetic field. Its robust structure is not easily deformed during long-term use, ensuring the stability of the magnetic core in the magnetic absorption layer 23 and providing a stable magnetic field foundation for the entire magnetic core assembly. The second magnetic core 26 and the third magnetic core 27 are formed by stacking multiple thin soft magnetic rings. The thin soft magnetic rings can respond more quickly when the magnetic field changes, and can adapt to different magnetic field requirements by adjusting their own magnetization state.
[0035] Furthermore, such as Figure 1 and Figure 2 As shown, a camera is installed on the charging pile 4; the camera faces the parking space 1; the camera is connected to the controller. The camera works in conjunction with the geomagnetic sensor 5 to ensure accurate determination of whether a vehicle has entered the parking space 1. While the geomagnetic sensor 5 can detect changes in the vehicle's magnetic field to determine if the vehicle is approaching or entering the parking space, detection errors may occur in some special cases, such as when the vehicle is moving slowly or in a complex geomagnetic environment. In such cases, the camera can provide the controller with intuitive visual information by capturing real-time images of the parking space 1. When the camera captures an image of the vehicle fully entering the parking space 1, and the geomagnetic sensor 5 also detects a corresponding change in the magnetic field, the controller can more accurately confirm that the vehicle has successfully entered the parking space 1, avoiding misjudgments that may occur due to a single detection method and improving the accuracy and reliability of parking space detection.
[0036] Furthermore, such as Figure 1 and Figure 2 As shown, a rubber ring 31 is provided at the top of the lifting driver 3 to seal the opening of the blind hole when in standby mode, which can prevent dust, debris and moisture from entering the blind hole and avoid damage to the lifting driver 3.
[0037] This embodiment provides an example of a smart parking garage based on geomagnetic sensing. After a vehicle parks in parking space 1, two geomagnetic sensors 5 detect the vehicle and immediately transmit signals to the controller. Simultaneously, a camera on the charging pile 4 facing parking space 1 captures the vehicle's entry in real time and transmits the image information to the controller. The two sensors corroborate each other to accurately determine whether the vehicle has successfully entered parking space 1. The controller then activates an upgraded driver to push the parking lock device 2 upwards through a blind hole in the center of parking space 1. The uppermost protective layer 21 of the parking lock device 2 first contacts the vehicle chassis. The carbon fiber composite layer of the protective layer 21 effectively resists possible physical impacts and wear, protecting the parking lock device 2. Next, the middle rubber magnetic buffer layer 22 provides cushioning and shock absorption, reducing rigid contact between the device and the vehicle chassis and preventing scratches. Simultaneously, its own magnetism, combined with the magnetic attraction layer 23, enhances the attraction effect on the vehicle. The bottom magnetic layer 23, after the excitation coil 24 is energized, the magnetic core assembly is magnetized, generating a strong magnetic force that attracts the metal parts of the vehicle chassis, firmly locking the vehicle. Then, parking timer starts, and the parking time and hourly parking fee are displayed on the billing display screen 41 on the charging pile 4, allowing the car owner to clearly understand the billing situation. If the vehicle is a new energy vehicle, the car owner can directly use the charging pile 4 on one side of the parking space 1 for charging. After parking, the car owner completes the payment operation at the payment window 42 on the charging pile 4. After payment, the controller receives a signal and controls the lifting drive 3 to lower the parking locking device 2 back into the blind hole. At this time, the rubber ring 31 at the top of the lifting drive 3 reseals the blind hole opening.
[0038] Example 2:
[0039] This embodiment provides a method for using the stopcock device of the pipe-removing tool described in Embodiment 1, including the following steps:
[0040] In this embodiment, the buffer layer 22 is a rubber magnetic layer, which combines the elasticity and magnetism of rubber. Its elasticity effectively buffers the impact between the parking lock device 2 and the vehicle chassis, protecting the vehicle and the device. Simultaneously, the magnetism of the rubber magnetic layer interacts with the magnetic field generated by the magnetic attraction layer 23, further enhancing the attraction force to the vehicle chassis and improving the reliability of the parking lock. The protective layer 21 is a carbon fiber composite layer, which features high strength and low density. It effectively resists external physical impacts and wear, protecting the internal structure of the parking lock device 2. The carbon fiber composite layer also has good corrosion resistance, maintaining stable performance even in harsh environments such as humidity and acid / alkali conditions, extending the service life of the parking lock device 2.
[0041] In this embodiment, the geomagnetic sensor 5 is provided with an anti-interference shield, which can effectively shield external electromagnetic interference and avoid mutual interference with the parking lock device 2.
