Description

Technical Field

[0001] This invention belongs to the technical field of intelligent parking management systems, specifically relating to a suspended intelligent parking space lock terminal and its parking space management method. Background Technology

[0002] With the continuous growth of urban motor vehicle ownership, parking resources in residential communities, commercial complexes, and office parks are becoming increasingly scarce. The rational use and effective management of parking spaces have become important issues for property management and urban management. Especially in scenarios involving privately owned parking spaces with fixed ownership or long-term usage rights, the shortage of parking spaces frequently leads to unauthorized vehicles occupying private spaces, resulting in increasingly prominent disputes, complaints, and management costs. On the other hand, privately owned parking spaces are often idle during certain periods. Owners of these spaces face various practical contradictions and difficulties when leasing them to the public, including poor information exchange with temporary renters, inconvenient overall management methods, lack of support from property management citing security concerns, and unfamiliarity with parking lot layouts among outsiders. These challenges prevent the idea of ​​using vacant privately owned parking spaces to alleviate the social parking problem from being realized. Meanwhile, when abnormal events occur, such as vehicles parked in parking spaces being hit by other vehicles, windows being smashed, trunks being pried open resulting in lost items, or vehicles being stolen, most of these events can only be passively discovered by the car owners afterward through visual observation. There is a lack of technical means to proactively identify these events and promptly notify the car owners and property management.

[0003] In existing technologies, parking space locks are typically installed to prevent unauthorized vehicles from occupying parking spaces. These locks are mostly mechanical, ground-mounted locks that physically block vehicles from entering the space using mechanisms such as lifting barriers or tilting mechanisms. While this method is effective to some extent, it still has many shortcomings in practical use.

[0004] First, ground-mounted mechanical parking locks need to be installed directly on the parking space floor. Installation typically involves drilling, damaging, or wiring the floor, which is not only complex and prone to causing irreversible damage to the parking lot floor, but also difficult to restore. Furthermore, in underground parking environments, water and dust accumulation are common. Ground-mounted parking locks, constantly exposed to these conditions, are prone to corrosion, jamming, and malfunction, affecting their lifespan and reliability.

[0005] Secondly, traditional parking locks rely on physical structures to provide obstruction, inevitably exposing themselves in the path of vehicles. In actual use, they are easily damaged by being run over or impacted due to driver error, limited visibility, or low vehicle chassis. Once damaged, not only are repair costs high, but liability is also difficult to determine, often requiring the parking space owner to bear the loss, which can easily lead to disputes.

[0006] Furthermore, existing mechanical parking locks have limited functionality, primarily serving only as physical barriers and unable to sense or record the real-time usage status of parking spaces. When unexpected incidents such as scratches, collisions, or theft occur while vehicles are parked in parking spaces, there is a lack of effective means of evidence collection. Parking space owners and property management often have to rely on manual patrols or post-incident coordination, resulting in low management efficiency and difficulty in resolving disputes.

[0007] Finally, traditional mechanical parking locks are generally divided into two types: manual and electric. The former requires getting out of the car to operate when opening and closing the parking lock, which is extremely inconvenient. The latter is difficult to power due to being installed on the ground, so it is basically powered by batteries, but the batteries need to be replaced regularly, resulting in a poor user experience.

[0008] As all sectors of society undergo a comprehensive digital transformation, parking lots have not seen significant improvements in their informatization and intelligentization levels. At the parking space management level, they are still largely at the stage of simply counting the number of available parking spaces. This is mainly because existing ground-based mechanical parking locks have limited functionality and are difficult to integrate effectively with parking fee management systems and other terminals. At the operational management level, they still rely on traditional methods such as manual monitoring and dispatching, primarily due to the lack of intelligent event perception and early warning technology for the entire parking lot. Overall, they cannot meet the needs for remote management, intelligent billing, parking space sharing, information push, and security early warning, and are ill-suited to the digital development trend of parking lot management.

[0009] In summary, existing parking lock technologies have significant shortcomings in terms of installation methods, structural security, status perception capabilities, security early warning functions, and integration with parking management systems. There is an urgent need for a technical solution that can avoid defects in ground installation, reduce the risk of physical damage, accurately identify the usage status of parking spaces, and intelligently perceive vehicle security events. Summary of the Invention

[0010] The purpose of this invention is to provide a suspended intelligent parking lock terminal and its parking space management method. By changing the installation method and operation mode of traditional parking locks, it can achieve accurate identification of parking space usage status and intelligent perception of vehicle safety events, so as to solve the problems of easy damage, difficult installation and maintenance, lack of security functions, and inability to effectively link with intelligent systems in the existing technology of ground parking locks.

[0011] To achieve the above objectives, the present invention adopts the following technical solution: a suspended intelligent parking lock terminal, comprising: a suspended intelligent parking lock terminal, the suspended intelligent parking lock terminal including a shell assembly, a suspension bracket module, and a component frame; the shell assembly including an LED display module, a wide-angle camera module, a network communication module, a microphone unit, a speaker unit, and a control circuit unit, and suspended above the parking space by the suspension bracket module; the component frame including a fisheye camera module, an ultrasonic radar array module, and a ground light, and disposed on the back of the shell assembly.

[0012] Furthermore, the component frame and the housing assembly are separable structures, meaning that the component frame can be located in other fixed positions, such as in another suspension bracket module or fixed to a wall, and connected to the housing assembly by a signal line.

[0013] Furthermore, the ultrasonic radar array module is used to measure the distance data between the suspended smart parking lock terminal and the ground of the parking space. The control circuit unit determines whether there is a vehicle parked in the parking space based on the changes in the distance data, and determines whether other objects enter the detection area during the parking period.

[0014] Furthermore, the fisheye camera module mainly captures images of the parking space area to record images of vehicles when parked; the wide-angle camera module mainly captures images of the lane area in front of the parking space to record images of vehicles leaving the parking space and lane images when abnormal events occur.

[0015] Furthermore, the speaker unit is used to continuously collect environmental noise data and send it to the server through the network communication module. After analysis by the AI ​​big model deployed on the server, it identifies specific audio of abnormal events such as collision sounds caused by a parked vehicle being hit, the sound of broken glass being shattered, the metallic sound of the trunk being pried open, and the sound of cries for help in the event of an emergency.

[0016] Furthermore, the control circuit unit determines the parking space status based on the distance data measured by the ultrasonic radar array module and generates a status control signal; the control circuit unit is communicatively connected to the network communication module, the server, and the user terminal; the network communication module is used to send the status control signal to the server.

[0017] Furthermore, the control circuit unit is electrically connected to the ground light, the LED display module, and the speaker unit. The control circuit unit is used to control the ground light to project a pattern with warning information onto the parking space floor through light illumination according to the status control signal, control the LED display module to display dynamic text information of different events, and control the speaker unit to emit prompt sounds or warning sounds.

[0018] Furthermore, it includes the following main steps: S1. The suspended intelligent parking lock terminal acquires distance data, image data, and environmental noise data of the parking space area; S2. Determine whether there is a vehicle parked in the parking space based on the distance data and the image data, and determine the current parking space status by combining the mode settings of the user terminal, including normal status, occupancy status, stolen status and abnormal status. S3. When the user terminal is set to no-parking mode, if a vehicle is detected to enter the parking space, it is judged as an intrusion state. The ground lights are controlled to switch frequently, the LED display module is controlled to display the warning state, the speaker unit is controlled to emit a warning sound and send an intrusion state signal to the server. S4. When the user terminal is set to parking mode, if the vehicle cannot be detected in the parking space, it is judged to be in a stolen state. The ground lights are controlled to frequently switch on and off, the LED display module is controlled to display the warning status, the speaker unit is controlled to emit a warning sound and send a stolen status signal to the server. S5. When the user terminal is set to parking mode, if the environmental noise data detects specific audio of events such as vehicle being hit, windows being broken, and trunk being pried open, and the change value of the distance data exceeds the threshold, it is judged as an abnormal situation and an abnormal status signal is sent to the server. S6. The server updates the parking space status according to the status signal and pushes it to the user terminal.

[0019] Furthermore, the method also includes: If the parking space is in an occupied state, the server will trigger the parking lot billing system to calculate the occupancy fee and collect it when leaving the parking lot; If the parking space is in a stolen state, the server will trigger the parking fee system to execute a command to prevent the vehicle from leaving the parking lot.

[0020] Beneficial Effects: This invention, by suspending the parking lock above the parking space, avoids the problems of traditional ground-mounted parking locks, such as susceptibility to being run over or impacted by vehicles, and electrical faults caused by moisture and dust accumulation. Structurally, this improves the safety and lifespan of the parking lock, while reducing ground-based construction and maintenance difficulties and facilitating power access. The suspended intelligent parking lock of this invention can sense the occupancy status of parking spaces in real time and perform status control and information feedback based on the sensing results. This transforms parking management from simple physical obstruction to a combination of intelligent sensing and management, significantly improving the level of intelligence in parking management.

[0021] This invention abandons the traditional physical barrier design, instead using electronic components such as cameras, ultrasonic radar, and microphones to collect, sense, and transmit parking space information. This enables timely judgment of the parking space and vehicle status and facilitates diverse notification interactions, serving as a V2I (Vehicle-to-Infrastructure) information infrastructure at the parking space level. Furthermore, when all parking spaces in a single parking lot are equipped with the parking locks of this invention, a microphone array for collecting ambient noise and a camera array for capturing images of the lane in front of the parking space can be formed. By deploying a large AI model trained with high-quality data, the system can proactively identify various abnormal events such as collisions with parked vehicles, broken windows, pried trunks, and distress calls using the audio array data. It can promptly notify relevant personnel and issue various warnings at the scene using the parking lock's LED screen, lights, and speakers. Simultaneously, the system can determine the location of one or more parking spaces corresponding to the abnormal event based on the volume of the collected audio, and then capture images of the incident area using the built-in camera of the parking lock so that relevant personnel can review the situation. The parking space management method of the present invention can be integrated into the parking management system and realize information interaction with various terminals, providing a technical foundation for remote management, intelligent billing, parking space sharing and autonomous driving, which is conducive to building a unified and efficient smart parking management system.

[0023] The following is in conjunction with the appendix Figure 1 To be continued Figure 7 The following describes specific embodiments of the present invention in further detail. Those skilled in the art should understand that the following embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit the scope of protection of the present invention.

[0024] As attached Figure 1 To be continued Figure 7As shown, the present invention provides a suspended intelligent parking lock terminal 100, including a housing assembly 110, a suspension bracket module 120, and a component frame 130. The housing assembly 110 has a rectangular parallelepiped structure and houses related electronic components such as an LED display module 111, a wide-angle camera module 112, a network communication module 113, a microphone unit 114, a speaker unit 115, and a control circuit unit 116. The LED display module 111 displays various interactive information, the wide-angle camera module 112 captures images of the lane area in front of the parking space, the network communication module 113 transmits data, the microphone unit 114 collects ambient noise, and the speaker unit 115 plays prompts or warning sounds. The control circuit unit 116 is electrically connected to the fisheye camera module 131, the ultrasonic radar array module 132, and the ground light 133 for unified control and processing of the various components. The control circuit unit 116 is also electrically connected to the LED display module 111 and the speaker unit 115 for outputting visual and sound prompts to the outside world.

[0025] The suspension bracket module 120 is used to fix the housing assembly 110 to the ceiling or beam structure above the parking space, thereby suspending the entire parking space lock device. The suspension bracket module 120 includes a chassis fixed to the ceiling and a connecting rod connected to the chassis. The connecting rod has a hollow channel inside for laying power lines and signal lines, allowing the parking space lock to obtain power from the parking lot lighting power supply system, avoiding the inconvenience of frequent battery replacements.

[0026] The component frame 130 is fixed to the back of the housing assembly 110 via a connecting structure. Inside, there is a fisheye camera module 131, an ultrasonic radar array module 132, and a ground illumination light 133. The fisheye camera module 131 is used to collect image information of the parking space area, the ultrasonic radar array module 132 is used to detect the distance between the parking space area and the parking lock, and the ground illumination light 133 is used to project a pattern with warning information onto the parking space floor.

[0027] In one implementation, when the parking lock is set to no-parking mode, after the parking space owner lifts the no-parking status via user terminal 300 or on-site control, the control circuit unit 116 will turn off the ground light 133 and control the LED display module 111 to display authorization prompt information. When a vehicle enters the parking space and is detected by the ultrasonic radar array module 132, the control circuit unit 116 will change the parking lock to parking mode. If the parking lock is not in no-parking mode, and a vehicle enters the parking space and is detected by the ultrasonic radar array module 132, the control circuit unit 116 will determine that the parking space is occupied and control the LED display module 111 to display warning information, control the ground light 133 to frequently switch on and off, and control the speaker unit 115 to emit a warning sound to remind and warn the driver of the vehicle committing the occupancy behavior.

[0028] Meanwhile, the control circuit unit 116 can send parking space status information to the server 200 via the network communication module 113. After processing the received information, the server 200 can push the parking space status to the user terminal 300, so that the parking space owner or parking lot manager can receive a timely notification that the parking space has been occupied, and view the current real-time image through the fisheye camera module 131 connected to the user terminal 300.

[0029] In another embodiment, when the parking lock is set to parking mode and the ultrasonic radar array module 132 can detect a parked vehicle, the control circuit unit 116 determines that the parking space is in a normal state, controls the fisheye camera module 131 to start shooting, records the parking process, and stores the relevant video data in the storage module. The parking space owner can view the current real-time image through the user terminal 300 or connect to the storage module to play back historical videos. When the parking lock is in parking mode and the ultrasonic radar array module 132 fails to detect a parked vehicle, or when it is in parking mode and receives a specific audio at the highest volume, the control circuit unit 116 determines that the parking space is in a stolen or abnormal state. In both cases, it controls the wide-angle camera module 112 to start recording, controls the LED display module 111 to display warning information, controls the ground lights 133 to frequently switch on and off, and controls the speaker unit 115 to emit a warning sound.

[0030] Furthermore, in the parking space management method of the present invention, when the system determines that the parking space is in an encroachment or theft state, the server 200 can also link with the parking lot billing system 400 to perform corresponding billing or restriction of exit operations according to the duration of encroachment, thereby constraining the encroachment behavior and preventing theft; when the system determines that the parking space is in an encroachment, theft, or abnormal state, the server 200 can also send a notification to the user terminal 300 to remind the parking space owner and the parking lot manager.

[0031] By combining the aforementioned hardware structure and management methods, this invention achieves intelligent perception and management of parking space status, solves the structural security issues of traditional ground parking space locks, and improves the management efficiency of property management companies for parking lots.

[0032] The following describes in further detail the suspended intelligent parking lock terminal 100 and its parking management method of the present invention with reference to different embodiments.

[0033] First embodiment: In this embodiment, the housing assembly 110 faces the lane, and its rear component frame 130 is located above the center line of the parking space. The component frame 130 is cylindrical, with a ground light 133 installed in the inner ring for projecting light onto the parking space floor. A fisheye camera module 131 is located on the outer ring of the bottom of the component frame 130 near the housing assembly 110, with its shooting direction vertically downwards for capturing images of the vehicle parking area. An ultrasonic radar array module 132 has three radar probes, also located on the outer ring of the bottom of the component frame 130. (See attached diagram) Figure 5 As shown, radar probe A is located on the outer ring of the side away from the housing assembly 110 and tilted outward at a 20-degree angle. It mainly covers the rear half of the ground when the parking space is vacant or the rear area of ​​the parked vehicle when the parking space is occupied. Radar probes B1 / B2 are located on the left and right sides of the bottom outer ring of the component frame 130 and tilted outward at a 30-degree angle. They mainly cover the left and right sides of the ground when the parking space is vacant or the left and right door areas of the parked vehicle when the parking space is occupied. All three radar probes are used to detect changes in the distance between the above-mentioned areas and the parking lock.

[0034] The control circuit unit 116 performs an initialization operation during the installation of the parking lock. Specifically, when the parking space is vacant, it acquires the distance data of radar probe A in the ultrasonic radar array module 132. This distance data is equal to the initial reference value between the parking lock and the parking space ground. Simultaneously, it acquires the parking space image information collected by the fisheye camera module 131 and converts it into image noise data, which is equal to the initial reference value when the parking space is vacant. Each time the parking lock switches to parking mode, the control circuit unit 116 separately records the current distance data between radar probes A / B1 / B2 in the ultrasonic radar array module 132 and the parked vehicle. This data is transmitted to the server 200 via the network communication module 113 for storage and subsequent verification and comparison.

[0035] At any time, if the difference between the distance data detected by radar probe A of ultrasonic radar array module 132 and the initial reference value exceeds a preset threshold, control circuit unit 116 determines that a vehicle is parked in the parking space. However, only in parking mode, when the current distance data set detected by radar probes A / B1 / B2 of ultrasonic radar array module 132 is compared with the distance data set stored when switching to parking mode most recently, and it is confirmed that one or more sets have changed and the change value exceeds a preset threshold, control circuit unit 116 determines that an object has entered near the left door, right door, or rear tailgate of the vehicle after the change continues for more than a preset time.

[0036] During the above judgment process, the control circuit unit 116 acquires the current image information collected by the fisheye camera module 131 and converts it into image noise data. The judgment result is verified by the deviation from the initial reference value data, thereby improving the accuracy of state recognition.

[0037] Second embodiment: In this embodiment, when the suspended smart parking lock terminal 100 detects that a parking space has been occupied by an unauthorized vehicle and the occupation lasts for more than a preset time threshold, the server 200 coordinates with the parking lot billing system 400 based on the received status information. The parking lot billing system 400 automatically generates an occupation record based on the start time of the occupation and calculates the occupation fee according to preset rules.

[0038] During the encroachment process, the LED display module 111 can display encroachment prompts and fee information in real time, and the speaker unit 115 emits a warning sound to make the driver aware of the consequences of continuing the current infringement. When the driver of the encroaching vehicle ends the encroachment and drives away from the parking space, the wide-angle camera module 112 transmits the real-time image to the server 200 for license plate number recognition, and then transmits the recognized license plate number to the parking fee billing system 400. When the encroaching vehicle leaves, the parking fee billing system 400 will restrict the vehicle from leaving until the encroachment fee is paid.

[0039] Furthermore, the handling of encroachment can be adjusted based on the parking space owner's settings or different management strategies. For example, in some parking lots, only an encroachment reminder is sent to the parking space owner or parking lot management without incurring charges; in other parking lots, it can be linked to the billing system to collect encroachment fees. All of the above different implementation methods are based on the same technical concept.

[0040] Third embodiment: In a single large parking lot, suspended smart parking lock terminals 100 can be installed above all parking spaces. Each parking lock transmits the collected environmental noise data to the server 200 via a microphone unit 114 and a network communication module 113. The data is then monitored and analyzed online by a dedicated large-scale model 210 deployed on the server 200. When collision sounds caused by a parked vehicle being hit, the sound of a car window breaking, the metallic sound of a trunk being pried open, or cries for help in an emergency are detected, the server compares the volume received by each parking lock and determines the specific location of the incident based on the actual distribution of the single or multiple parking locks with the loudest volume. The server 200 can then promptly send a message to the user terminal 300 used by the property management. Simultaneously, the server 200 sends control signals to the single or multiple parking locks with the loudest volume, causing the control circuit unit 116 of each parking lock to activate the wide-angle camera module 112 to capture images of the lane and transmit the video data back to the server 200 via the network communication module 113, facilitating subsequent review of the incident by the property management.

[0041] Fourth embodiment: In normal parking mode, when the current distance data set detected by the radar probes A / B1 / B2 of the ultrasonic radar array module 132 is compared with the distance data set stored when the vehicle was last switched to parking mode, and it is confirmed that one or more sets have changed and the change value exceeds a preset threshold, the control circuit unit 116 determines that an object has entered the vicinity of the vehicle's left door, right door, or rear tailgate after the change continues for more than a preset time. For example, if someone stays next to the vehicle for a long time, the control circuit unit 116 controls the ground lights 133 to frequently switch on and off to create flashing lights, the LED display module 111 to display prompt information, and the speaker unit 115 to emit a prompt or warning sound, depending on the duration of the suspicious situation.

[0042] In the third embodiment, when the large model 210 deployed on the server 200 identifies a specific sound, the server 200 will send control signals to the single or multiple parking locks with the loudest receiving volume. The parking lock control circuit unit 116 set to parking mode will compare the current detection distance data of the ultrasonic radar array module 132. Only when an object enters the area corresponding to the vehicle within that time period can it be determined that the abnormal event occurred in the parking space, and then a message will be sent to notify the owner of the parking space.

[0043] As can be seen from the above embodiments, the suspended intelligent parking lock terminal 100 and its parking management method of the present invention can adapt to different parking lot environments and management needs, and have strong applicability and scalability. To further enable those skilled in the art to fully understand the technical concept and implementation of the present invention, the key structures, working processes, and variations under different application conditions in each embodiment are further described in detail below without departing from the core concept of the present invention.

[0044] During the installation and implementation of this invention, the top of the parking lot is typically a concrete slab. The suspension bracket module 120 is fixed to the slab structure using expansion bolts or embedded parts, thereby providing a reliable load-bearing foundation for the entire parking space lock device. The connecting rods in the suspension bracket module 120 form a through-hole hollow channel for laying power and signal lines, allowing the housing assembly 110 to be directly connected to the existing lighting power supply or dedicated power supply line in the parking lot.

[0045] In different parking lot environments, the structure of the canopy above the parking space may vary; for example, the top may be a reinforced concrete slab, a steel beam structure, or a prefabricated composite structure. To address these differences, the chassis of the suspension bracket module 120 can be fixed using different methods depending on the actual load-bearing structure. In a concrete slab environment, the chassis can be reliably fixed using expansion bolts; in a steel beam structure environment, it can be fixed using clamps or connecting plates. These methods enable the suspension bracket module 120 to stably support the weight of the outer shell assembly 110 and its internal functional modules.

[0046] As an important component of the suspension bracket module 120, the connecting rod's length can be adjusted according to the parking space height to ensure a suitable distance between the housing assembly 110 and the parking space floor. On one hand, this distance should ensure that the fisheye camera module 131 and the ultrasonic radar array module 132 can cover the entire parking space area; on the other hand, it should also avoid the devices being positioned too low and interfering with vehicle passage. Through this adjustable design, the present invention can adapt to parking lot environments with different floor heights.

[0047] Additionally, in some parking spaces, the presence of ventilation ducts, fire hydrants, or other facilities may prevent installation due to insufficient height. To address these issues, the housing assembly 110 and component frame 130 can be installed separately. Specifically, one suspension bracket module 120 is installed at the top of the parking space near the driveway, supporting the housing assembly 110 to avoid obstructing pipes above the parking space; the other suspension bracket module 120 is installed at the top of the other end of the parking space or on the exterior wall, supporting the component frame 130 at an angle rather than vertically aligned with the center point of the parking space, thus resolving the insufficient installation height issue.

[0048] In the parking space management method of the present invention, the execution order and triggering conditions of each step can be adjusted according to actual application needs. In one embodiment, the system immediately executes the status determination and prompting steps after detecting a change in the parking space status; in another embodiment, the system can set a time buffer mechanism, executing subsequent steps only if the status change lasts for more than a preset time, thereby avoiding false triggering caused by short-term interference. The network communication module 113 plays a crucial role in uploading parking space status information to the server 200, establishing a communication connection with the server 200 through a dedicated wireless network deployed in the parking lot, and periodically or when the status changes. After receiving the data, the server 200 records and analyzes the parking space status and pushes the processing results to the user terminal 300.

[0049] User terminal 300 can be a mobile phone, tablet, or other smart terminal. The application running on it can display the real-time status, historical records, and relevant prompts of the parking space to the user, and allow for interactive operations. In this way, parking space owners can understand the parking space status without going to the site, improving the convenience of management.

[0050] In one implementation, private parking space owners in a residential community can share their parking spaces with other vehicles when they are vacant via a user terminal 300. Drivers of these shared vehicles can pre-book a space by registering and completing real-name authentication through the user terminal 300. The user terminal 300 then sends vehicle information to a server 200, which pushes this booking information to a parking fee system 400. Upon arrival at the parking lot entrance, the parking fee system 400 correctly identifies the vehicle, allowing it to enter. Drivers can quickly locate their reserved parking spaces using the guidance provided by the user terminal 300. Simultaneously, the parking space lock above the space displays the vehicle's license plate number and a welcome message via an LED display module 111. This method allows parking space owners to easily set up parking space sharing rules, eliminates the need for excessive intervention by property management personnel, and enables drivers to quickly find shared parking spaces. This increases the effective supply of parking spaces and alleviates the overall parking problem in society.

[0051] Large public parking lots may experience parking shortages during certain periods. Drivers of private vehicles can pre-book parking spaces by registering and completing real-name authentication through a user terminal 300. The user terminal 300 sends vehicle information to the server 200, which then pushes this information to the parking fee system 400. The parking fee system 400 reserves an available parking space for the pre-booked period. When a vehicle arrives at the parking lot entrance and is correctly identified by the parking fee system 400, it can enter the parking lot normally. The parking fee system 400 immediately assigns an available parking space and guides the driver to the reserved space via the user terminal 300. Simultaneously, the parking space lock above the space displays the vehicle's license plate number and a welcome message via an LED display module 111. This method allows drivers to secure parking during peak hours by pre-booking, avoiding the time and energy wasted searching for spaces and improving their travel experience.

[0052] As can be seen from the detailed description of the above embodiments, the present invention, through the combination of suspended installation structure, intelligent sensing and digital management methods, can effectively solve the problems of easy damage to ground parking space locks, low management efficiency, single management method and difficulty in achieving intelligent linkage in the prior art, and provides a feasible implementation plan for solving social parking problems.

[0053] Based on an understanding of the technical concept of this invention, those skilled in the art can make reasonable adjustments to the implementation methods according to specific application scenarios, and all such adjustments should be considered to fall within the protection scope of this invention.
