[0036] To address the above problems, embodiments of this application propose a parking management system, which mainly relates to parking lot vacancy space guidance management technology included in parking lot technology. These embodiments will be described in detail below.

[0037] Please refer to the following first. Figure 1 , Figure 1 This is a schematic diagram illustrating a parking management system as shown in an exemplary embodiment of this application. Figure 1 As shown, in an exemplary embodiment, the system includes a geomagnetic detector 10, an outdoor controller 20, and a guide screen 30, wherein the outdoor controller 20 is connected to the geomagnetic detector 10 and the guide screen 30;

[0038] The geomagnetic detector 10 is installed in the parking space of the parking lot to monitor the parking space status and transmit it to the outdoor controller 20. The outdoor controller 20 transmits the available parking space information obtained based on the parking space status to the guidance screen 30 for display, so as to guide vehicles into the available parking space of the parking lot.

[0039] In use, the geomagnetic detector 10 inside the parking space monitors the parking space status in real time and transmits it to the outdoor controller 20 in real time. The outdoor controller 20 analyzes the parking space status to determine whether the corresponding parking space is empty, integrates all empty parking spaces in the parking lot to obtain empty parking space information, and then transmits the empty parking space information to the guidance screen 30 for display, so that car owners who drive into the parking lot or intend to enter the parking lot can reach the empty parking space according to the empty parking space information displayed on the guidance screen.

[0040] As can be seen from the above, in this embodiment, the geomagnetic detectors installed in the parking spaces accurately determine the parking space status. The outdoor controller transmits the available parking space information obtained based on the parking space status to the guidance screen for display, guiding vehicles to enter the available parking spaces in the parking lot. Guiding drivers to park quickly saves parking time, reduces air pollution, and achieves energy conservation and environmental protection. Furthermore, accurate guidance of available parking spaces improves the convenience of parking lot management and fully utilizes all available parking spaces in the parking lot, avoiding the problem of long-term vacancy of parking spaces in poor locations, thereby improving the space utilization rate of the parking lot. In addition, the parking management system includes hardware devices such as geomagnetic detectors and guidance screen lights, which occupy a small area, are easy to deploy, do not significantly affect the spatial layout of the parking lot, have a simple architecture, can be interoperated with other systems, and have high functional scalability.

[0041] Optionally, in an exemplary embodiment of this application, the geomagnetic detector includes an oscillation circuit and a frequency measurement circuit, which are connected together; the geomagnetic detector detects the oscillation signal in the parking space in real time through the oscillation circuit, and determines the parking space status based on the oscillation frequency change in the parking space obtained from the oscillation signal through the frequency measurement circuit.

[0042] In this embodiment, the geomagnetic detector adopts a protection design with a protection rating of up to IP65. During use, the oscillation signal has stable and reliable characteristics. The oscillation circuit detects the oscillation signal in the parking space in real time. When a large metal object, such as a car, passes by, the oscillation frequency changes due to the change in the spatial medium (the oscillation frequency increases when there is a metal object). This change serves as a confirmation signal of the car passing by the geomagnetic detector and is captured by the frequency measurement circuit. The microcontroller in the frequency measurement circuit can then measure the change in oscillation frequency and thus determine the parking space status with an accuracy rate of 98%. In addition, the time interval between the start and end of this signal can also be used to measure the car's speed.

[0043] Optionally, the oscillation circuit includes a ground inductor and a capacitor, with the ground inductor buried in a recessed area in the center of the parking space. Specifically, a circular trench, approximately 1 meter in diameter, or a rectangular trench of similar area, is first created in the ground of the parking space. Wires are then buried in this trench, thus forming a ground inductor buried in the ground. This method of burying the coil in the center of the parking space provides waterproofing, snowproofing, corrosion resistance, pressure resistance, and strong anti-interference capabilities, effectively coping with outdoor environments and allowing for normal operation under various weather conditions.

[0044] Optionally, the inductance of the ground inductor is in the range of 100uH to 300uH.

[0045] To ensure the detector operates at its optimal state, the coil inductance should be maintained between 100uH and 300uH. With a constant coil inductance, the number of turns is significantly related to the coil's circumference; a smaller circumference requires more turns, as shown in Table 1 below.

[0046] Table 1:

[0047]

[0048] If the circumference of the inductive loop is less than 3 meters, the number of turns should be set according to the actual situation to ensure that the inductance value is between 100uH and 200uH. Since various cables, reinforcing bars, manhole covers, and other metal materials may be buried under the road, these will significantly affect the actual inductance value of the loop. Therefore, the data in the table above is for reference only. During actual construction, users should use an inductance tester to actually test the inductance value of the inductive loop to determine the actual number of turns, as long as the final inductance value of the loop is within a reasonable operating range (e.g., between 100uH and 300uH).

[0049] As can be seen from the above, in the parking management system provided in the above embodiments, the geomagnetic detector adopts a protection design with a protection level of up to IP65, which can effectively cope with various harsh environments of outdoor parking spaces. The use of inductive loop metal identification and judgment methods can achieve an accuracy rate of over 98% in detecting the status of parking spaces, and it has strong anti-interference capabilities, with no impact on underground parking lots, outdoor parking lots, or indoor parking lots. The inductive loop included in the oscillation circuit is embedded in the ground groove in the middle of the parking space, eliminating aesthetic concerns, reducing construction difficulty, and the small size of the geomagnetic detector minimizes damage to the ground at the parking lot entrance and exit.

[0050] Optionally, in an exemplary embodiment of this application, the outdoor controller includes an outdoor central controller and multiple outdoor area controllers, with the outdoor central controller connected to the multiple outdoor area controllers to form a multi-level routing structure. For example... Figure 2 As shown, Figure 2 This is a schematic diagram of a multi-level routing structure consisting of an outdoor central controller and an outdoor area controller in an exemplary embodiment of this application. Multi-level routing, also known as nested routing, refers to a routing rule containing other routing rules within a single routing rule, forming a hierarchical routing structure.

[0051] In use, the outdoor area controller communicates wirelessly with the geomagnetic detector. The outdoor controller compresses and encodes the parking space status and transmits it to the outdoor central controller. The outdoor central controller then processes the data to obtain the available parking space information.

[0052] In this embodiment, the outdoor area controller and the outdoor central controller adopt internationally advanced AI processors and a fully industrial-grade design to ensure system stability and reliability. Furthermore, both the outdoor area controller and the outdoor central controller feature waterproof and dustproof designs with an IP65 protection rating, enabling them to adapt to harsh outdoor environments. Figure 3 As shown, Figure 3 This is a schematic diagram illustrating the interface of an outdoor area controller used in an exemplary embodiment of this application. In specific applications, the various interface parameters of the outdoor area controller can be set similarly as required.

[0053] Thus, through the above embodiments, this application utilizes a multi-level routing structure composed of an outdoor centralized controller and outdoor area controllers to perform hierarchical control of data transmitted within the parking lot, improving data processing efficiency and enhancing the system's networking capabilities. Furthermore, the outdoor area controllers and geomagnetic detectors communicate wirelessly, reducing construction wiring and subsequent maintenance costs.

[0054] Optionally, in an exemplary embodiment of this application, the guide screen includes a small guide screen and a large guide screen;

[0055] Small guidance screens are placed at the intersections within the parking lot to display information on available parking spaces within the corresponding management area; large guidance screens are placed at each entrance of the parking lot to display information on all available parking spaces within the parking lot.

[0056] When in use, the small guidance screen displays the available parking spaces in the corresponding management area at the intersections within the parking lot, while the large guidance screen displays all available parking spaces in the parking lot at each entrance. Drivers can choose to go to the corresponding available parking space according to the different guidance screens, avoiding drivers having to visually search for available parking spaces in the parking lot, thus reducing parking time and exhaust emissions.

[0057] Optionally, the guidance screen includes an outdoor high-brightness P10 odd / even number / P5 full-color module, a driving unit, and a screen bracket. For example, in practical applications, the guidance screen is installed at the intersection of a parking lot using the screen bracket; the driving unit controls the outdoor high-brightness P10 odd / even number / P5 full-color module to display the available parking space information within the corresponding management area.

[0058] In use, the guidance screen receives output information from the outdoor centralized controller and displays the number of available parking spaces in the area using numbers, arrows, etc., guiding drivers to quickly find available parking spaces and ensuring smooth traffic flow and full utilization of parking spaces. One-way, two-way, and three-way guidance screens can be customized as needed. In this embodiment, the parameter settings for the guidance screen are shown in Table 2 below.

[0059] Table 2:

[0060]

[0061] Optionally, the guide screen includes a high-brightness LED module, a driving circuit, and a screen bracket;

[0062] The guidance screen is installed at each entrance of the parking lot via a screen bracket; the drive circuit controls high-brightness LED modules to display information on all available parking spaces in the parking lot.

[0063] In use, the guidance screen displays the current number of available parking spaces in real time using numbers and text, prompting drivers preparing to enter the parking lot. It is available 24 / 7. Multi-level, multi-parking lot display areas can be customized to meet specific needs. In this embodiment, the parameter settings for the guidance screen are shown in Table 2 below.

[0064] Table 3:

[0065]

[0066] In the embodiments provided in this application, the small and large guidance screens adopt tempered glass panels and cold-rolled steel painted shells, featuring a simple and elegant appearance. The shells are waterproof and dustproof, and use UV-resistant paint, making them resistant to discoloration. Furthermore, when the small guidance screen manages multiple areas or the large guidance screen manages multiple parking lots, arrows on the small screen point to different management areas, and arrows on the large guidance screen point to different parking lots. Red and green dual-color indicators can be used, offering advantages such as clear visibility, high LED light intensity, long viewing distance, and wide viewing angle. Additionally, the small guidance screen also has short-circuit, overvoltage, overcurrent, and overload protection functions.

[0067] Optionally, in an exemplary embodiment of this application, the parking management system further includes a vehicle recognition subsystem and an integrated management platform. The vehicle recognition subsystem is connected to the outdoor controller and is used to acquire license plate information and synchronously store it in a database along with the matching parking space status for querying.

[0068] When in use, the vehicle recognition subsystem acquires license plate information and transmits the data to a computer, which then stores the data in a database. Users can then query real-time parking space information and annual, monthly, and daily statistics of the parking lot through a computer terminal.

[0069] Please see Figure 4 , Figure 4 This is a schematic diagram of a parking management system in an exemplary embodiment of this application, as shown below. Figure 4 As shown, the integrated management platform is connected to the geomagnetic detector, outdoor controller, and guide screen to monitor the geomagnetic detector, outdoor controller, and guide screen in real time, obtain statistical information, and display it.

[0070] When in use, the integrated management platform monitors the geomagnetic detectors, outdoor controllers, and guidance screens in real time to obtain statistical information, which is then transmitted to the user terminal for display. In this way, users can view the time when the detector data is refreshed and the parking lot space occupancy status data in real time. It can realize parking lot traffic statistics, parking lot utilization statistics, and parking space utilization statistics, and generate icons so that users can view the parking lot operation status at any time.

[0071] Specifically, the management functions implemented by the integrated management platform can include: parking space status management, allowing supervisors to view on-site parking space usage from the management room, along with detector disconnection alerts; online map management, used to add maps, import parking space icons and guidance screens, associate relevant guidance screens and parking spaces, and download data to the controller so that the guidance screens can display data in real time, while also enabling the entire system to run offline; parking lot operation analysis, which can realize parking lot traffic statistics, parking lot utilization rate statistics, and parking space utilization rate statistics, generating icons so that operators can view the parking lot operation status in real time; parking space data analysis, which realizes parking space occupancy status data information, parking lot traffic statistics, parking lot utilization rate statistics, and parking space utilization rate statistics; and online equipment management, which enables real-time monitoring of parking space status, online equipment management, and remote configuration, allowing supervisors to view on-site parking space usage from the management room, along with detector disconnection alerts.

[0072] As can be seen from the above embodiments, the parking management system can improve the intelligence and informatization level of the entire parking lot, entrusting problems that originally required manual processing to intelligent equipment, thus saving a significant amount of labor costs and ensuring the timeliness, accuracy, and effectiveness of various data. Drivers can quickly and easily find parking spaces through various guidance devices, saving considerable time and making the parking lot appear more perfect.
