Description

Technical Field

[0001] This invention belongs to the field of berth navigation technology, specifically relating to an area berth navigation system and its navigation method. Background Technology

[0002] With the acceleration of urbanization and the surge in motor vehicle ownership, smart parking technology, as an important solution to alleviate parking difficulties, is seeing its application scenarios and market demand expand rapidly. Existing smart parking systems mostly rely on mobile applications (APPs) or mini-programs, improving parking management efficiency and user experience through functions such as electronic payment, order management, and parking space search. For example, users can use the APP to view parking lot locations, pricing standards, and other information in real time, and complete remote payment. However, the core functions of current smart parking systems still focus on the transaction process, lacking effective support for users' pre-parking route planning and dynamic parking space navigation needs, making it difficult to meet the actual needs of efficient parking in complex urban traffic environments.

[0003] In the prior art, Chinese patent document CN105631523A proposes a smart parking system and method, which solves the technical problem of online parking space reservation by reserving parking spaces online through terminal devices and using parking space occupancy posts and smart switches to control the locking and releasing of parking spaces. However, this solution still has the following limitations: First, its core functions revolve around parking space reservation and status control, failing to address the user's need to obtain real-time parking space occupancy status during driving. Traditional smart parking apps or mini-programs usually only display the total number of parking spaces and cannot dynamically update the occupancy information of individual parking spaces, causing users to still need to blindly search for available parking spaces after arriving at the parking lot; Second, the existing technology lacks a linkage mechanism with parking lot guidance screens, making it impossible to display parking space status and guidance information in real time along the user's driving path, making it difficult for users to plan the optimal driving route in advance. For example, users may be forced to turn into other parking lots midway because they cannot predict the number of remaining parking spaces in the target parking lot, resulting in a waste of time and energy.

[0004] In summary, while existing smart parking technologies are relatively mature in terms of payment and order management, they still have significant shortcomings in real-time parking navigation, dynamic route planning, and integration with guidance facilities. Especially in densely populated urban areas, users urgently need a solution that can perceive parking space status in real time, dynamically correlate with guidance screens, and generate optimal navigation routes to improve parking efficiency and reduce traffic congestion. Therefore, to address the deficiencies of existing technologies, there is a pressing need to propose an innovative regional parking navigation system and method that integrates parking space status perception, multimodal guidance, and intelligent route planning to optimize the entire process from user driving decisions to parking completion. Summary of the Invention

[0005] To address the problems in related technologies, this invention proposes a regional parking space navigation system and its navigation method to solve the shortcomings of existing smart parking technologies in terms of real-time parking space navigation, dynamic path planning, and linkage with guidance facilities.

[0006] The technical solution of this invention is implemented as follows: a regional berth navigation system, comprising:

[0007] Cloud servers, parking management systems, guidance screens, guide lights, and mobile devices;

[0008] The navigation area has multiple roads, with road intersections forming road nodes. Each road node is equipped with a guidance screen and guide lights. Each road extends to a corresponding parking lot, and each parking lot contains multiple parking spaces.

[0009] The parking management system is installed in each parking lot to identify the occupancy status of parking spaces in real time and synchronize the parking space status information to the cloud server.

[0010] The guidance screen includes a display body and a base shell. The display body can be folded and placed on top of the base shell. The guidance screen is connected to a cloud server to display parking information, including the direction of the parking lot, the total number of parking spaces, and the number of remaining parking spaces. The parking information is distinguished by different colors for different parking lots and is consistent with the color of the guide lights.

[0011] The guide lights are installed on the corner shoulders of road nodes and extend along the road turning direction; each guide light is communicatively connected to the guidance screen, synchronized with the corresponding parking lot color indicated on the guidance screen, and guides the vehicle's driving direction in an intermittent flashing mode;

[0012] The mobile device is equipped with a smart parking APP or mini-program. Users can connect to the cloud server through the mobile device to obtain parking space status information and navigation routes. The navigation routes are generated based on the user's input destination, real-time traffic conditions, and the number of remaining parking spaces in the parking lot, and are linked with the guidance screen and guide lights to dynamically adjust the guidance information.

[0013] This invention connects a guidance screen to a cloud server, displaying real-time parking information including parking lot direction, total number of parking spaces, and remaining spaces. Different colors distinguish different parking lots, and the guide lights are synchronized with the screen, allowing users to intuitively follow the navigation route without frequently operating their phones; they can simply observe the guide lights. Furthermore, based on the user-input destination, real-time traffic conditions, and remaining parking spaces, a navigation route is dynamically generated. Users can know the availability and precise location of parking spaces in advance while driving, enhancing the travel experience and significantly improving the real-time performance of parking navigation.

[0014] As a further improvement to the above solution, the display body includes at least two foldable screens connected by hinges to allow the display body to be folded in half and stored on the top surface of the base shell; it also includes a locking fastener for fixing the folded display body; the locking fastener includes a hook and a buckle, and the display body is locked and fixed by the hook and the buckle after being folded in half;

[0015] The top surface of the base shell is provided with a slot, which is horizontally located in the middle of the base shell. The bottom of the display screen body is snapped into the slot to achieve vertical insertion of the display screen body. The top surface of the base shell is also provided with a slider seat, and the bottom of the display screen body is provided with a sliding groove. The display screen body is folded flat by sliding and rotating the slider seat and the sliding groove. The sliding groove is provided with a rotation groove and a flat groove. After the display screen body is disengaged from the slot, it moves along the rotation groove to the flat groove to achieve switching between vertical and flat states.

[0016] As a further improvement to the above solution, a signal transmission cable is connected between the two foldable screens, and the signal transmission cable is covered with a telescopic protective sleeve; the base shell of the induction screen includes a hollow bottom cavity with built-in counterweights to lower the center of gravity;

[0017] The roller assembly is located at the bottom of the base shell; the two side walls of the base shell are equipped with mutually compatible hooks and holes; multiple guidance screens are connected in a row and moved via hooks and holes. It should be noted that traffic networks are subject to significant random changes; configuring a movable and foldable guidance screen structure facilitates the rapid storage, movement, and deployment of the screens, reducing maintenance costs. Furthermore, the ability to move multiple guidance screens in a row via hooks and holes allows for easy movement by a single person, reducing manpower. The retractable protective sleeve effectively protects the signal transmission cables, ensuring transmission stability and simplifying folding operations. For example, during peak traffic periods like holidays, staff can drag multiple guidance screens in a row to temporary road nodes to expand the guidance coverage; in everyday scenarios, they can be folded for storage to reduce space requirements.

[0018] As a further improvement to the above solution, the guide light includes: a light body, a control unit, and a wireless communication module;

[0019] The control unit is connected to a wireless communication module to receive parking space status information and color coding instructions sent by the guidance screen;

[0020] The light body is equipped with an RGB LED module, which switches the light emission color according to the color coding instruction and synchronizes with the corresponding color of the parking lot indicated on the guidance screen.

[0021] The intermittent flashing mode includes: flashing at a first frequency when the number of remaining berths is greater than a preset threshold; switching to a second frequency when the number of remaining berths is lower than the threshold; and turning off the lights when there are no remaining berths.

[0022] Different parking lots are distinguished by different colors, so that users do not need to frequently operate their mobile phones while driving. They only need to observe the prompts of the guidance screen and the guide lights to clearly understand the location of the parking lot and the remaining parking spaces, so as to prepare for driving in advance. This realizes the effective linkage between the guidance screen and the navigation system, and further improves the convenience of parking. It should be noted that the existing technology lacks a linkage mechanism with the parking lot guidance screen, and cannot display the parking space status and guidance information in real time through the guidance screen in the user's driving path. This invention constructs a multimodal guidance system through the collaborative work of the guidance screen and the guide lights: (1) The guidance screen distinguishes parking lots by color and combines key information such as directional arrows and the number of remaining parking spaces to provide users with a macro-path decision basis; (2) The guide lights extend along the road turning direction, and their colors are consistent with the corresponding parking lots marked by the guidance screen. The visual guidance effect is enhanced by the intermittent flashing frequency. This linkage mode of "large screen global guidance + small light detailed guidance" enables users to quickly identify the direction of the target parking lot in complex road networks, reduce driving hesitation and path errors. Especially at night or in bad weather, the light guidance can significantly improve driving safety.

[0023] As a further improvement to the above solution, the guide light also includes:

[0024] An optical distance sensor, located on the side of the light body, is used to detect the real-time distance between the vehicle and the guide light;

[0025] The control unit adjusts the headlight brightness according to the vehicle distance, and the relationship between the brightness value L and the distance d satisfies the formula:

[0026] L = L max ×e -k·d ;

[0027] Among them, L max Where d is the maximum brightness, k is the attenuation coefficient, and d is the straight-line distance between the vehicle and the guide light.

[0028] The brightness of the guide lights varies with the distance to the vehicle, which not only effectively saves energy but also avoids excessive light pollution and ensures driving safety.

[0029] As a further improvement to the above solution, the smart parking APP or mini-program includes:

[0030] The map interface module integrates third-party map resources and displays berth status data with a map background.

[0031] The positioning module obtains the user's real-time location and loads information about nearby parking spaces after user authorization.

[0032] The search module supports inputting road segments or business names as destinations and generating navigation routes by associating parking data.

[0033] The reservation module is linked to the parking lot barrier. After a user selects a reserved parking space, the barrier rises and locks the space until the user arrives or the time expires.

[0034] Smart parking apps or mini-programs can be configured with map integration, merchant association, and reservation functions to provide one-stop parking and surrounding service information, thereby improving the user experience for navigation users.

[0035] As a further improvement to the above solution, the map interface module also includes:

[0036] The layered display function shows the real-time number and location of remaining parking spaces on the first layer, and overlays information on surrounding merchants and consumption data on the second layer.

[0037] The path planning algorithm calculates the shortest path P based on real-time traffic conditions. short and the congestion avoidance path P avoid The path weight W satisfies:

[0038] W = α·t + β·d + γ·s;

[0039] Where t is the estimated passage time, d is the distance, s is the number of remaining berths, and α, β, and γ are adjustable weighting coefficients.

[0040] The navigation routes generated on mobile devices are not only based on the user's input destination, but also dynamically adjusted by integrating real-time traffic conditions, the number of remaining parking spaces in parking lots, and the status of guidance screens / lights. For example, when the number of remaining parking spaces in a parking lot approaches zero, the system automatically guides the user to a nearby vacant parking lot and updates the color markings on the guidance screens and switches the flashing modes of the guidance lights to achieve a balanced distribution of traffic flow across the entire area. In addition, the route planning algorithm incorporates weighting factors (such as distance, time, and number of parking spaces) to calculate the optimal route, balancing efficiency and parking success rate, thus alleviating local congestion at its source.

[0041] As a further improvement to the above solution, the cloud server also includes:

[0042] The dynamic scheduling module calculates the optimal parking lot recommendation priority based on the number of remaining parking spaces in each parking lot and the road congestion index.

[0043] The priority score S i For the i-th parking lot, the following conditions must be met:

[0044]

[0045] Where, N i N represents the number of remaining berths. total T represents the total number of berths. i The estimated time from the current location to the parking lot is represented by w1 and w2, which are weighting coefficients.

[0046] The parking space navigation system in this area can identify the occupancy status of parking spaces in real time and quickly synchronize the parking space status information to the cloud server. Users can connect to the cloud server via their mobile devices to obtain accurate real-time parking space status, plan their parking strategies in a timely manner, effectively avoid unnecessary time wasted searching for parking spaces after arriving at the parking lot, and greatly improve parking efficiency.

[0047] As a further improvement to the above solution, the dynamic scheduling module is also configured with:

[0048] In emergency mode, when a sudden traffic incident is detected, the guide light color codes are reassigned, and the recommended priority of parking lots in the affected area is downgraded.

[0049] The emergency mode is triggered when the average vehicle speed V on a certain road segment in the real-time traffic data satisfies: V <V threshold Furthermore, the duration exceeds a preset threshold. Users can know the availability and precise location of parking spaces in various parking lots in advance while driving. Combined with real-time traffic information, the system plans the optimal driving route for users, avoiding congested areas and improving their travel experience.

[0050] A method for berth navigation in an area, applied to an area berth navigation system as described above, includes the following steps:

[0051] S1: The parking management system collects the occupancy status of each parking space in real time and uploads it to the cloud server;

[0052] S2: The guidance screen obtains the remaining parking space data from the cloud server, distinguishes parking lots by color coding, and displays the data dynamically.

[0053] S3: The mobile device receives the user's input destination and generates a navigation route by combining real-time traffic conditions and remaining parking spaces;

[0054] S4: Activate the guide lights at the corresponding road nodes according to the navigation route, and guide the vehicle to drive by color synchronization and intermittent flashing;

[0055] S5: When a user selects a reserved parking space, the control of the parking space barrier is used to lock the space and start a countdown. The parking space is automatically released after the countdown expires.

[0056] Beneficial effects:

[0057] (1) Enhanced linkage with guidance facilities: The guidance screen communicates with the cloud server, displaying real-time parking information including parking lot direction, total number of parking spaces, and number of remaining parking spaces. Different colors are used to distinguish different parking lots, eliminating the need for users to frequently operate their mobile phones while driving. By simply observing the prompts on the guidance screen and the guide lights, users can clearly understand the location of the parking lot and the availability of parking spaces, allowing them to prepare for their journey in advance. This achieves effective linkage between the guidance screen and the navigation system, further improving parking convenience.

[0058] (2) Optimized route planning capabilities: Existing technologies lack a linkage mechanism with parking lot guidance screens, making it difficult for users to plan the optimal driving route in advance. This system, however, dynamically generates navigation routes based on the user's input destination, real-time traffic conditions, and the number of remaining parking spaces. Users can know the availability and precise location of parking spaces in each lot in advance while driving. Combined with real-time traffic information, the system plans the optimal driving route for the user, avoiding congested areas and improving the travel experience.

[0059] (3) Significantly Improved Real-Time Parking Navigation: Traditional smart parking apps or mini-programs only display the total number of parking spaces and cannot dynamically update the occupancy information of individual spaces, causing users to blindly search for available spaces after arriving at the parking lot. This area's parking navigation system can identify the occupancy status of parking spaces in real time and quickly synchronize the parking status information to the cloud server. Users can connect to the cloud server via their mobile devices to obtain accurate real-time parking status, plan their parking strategies in a timely manner, effectively avoid unnecessary time wasted searching for spaces after arriving at the parking lot, and greatly improve parking efficiency.

[0074] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0075] Example:

[0076] like Figure 1-6 As shown, an area berth navigation system includes:

[0077] The system includes a cloud server, a parking management system, a guidance screen 1, a guide light 2, and a mobile terminal. The navigation area has multiple roads, with road intersections forming road nodes. The guidance screen 1 and guide light 2 are located near each road node. Each road extends to a corresponding parking lot, and each parking lot contains multiple parking spaces.

[0078] The parking management system is installed in each parking lot to identify the occupancy status of parking spaces in real time and synchronize the parking space status information to the cloud server.

[0079] The guidance screen 1 includes a display screen body 11 and a base shell 12. The display screen body 11 can be folded and placed on top of the base shell 12. The guidance screen 1 is connected to a cloud server to display parking information, including the direction of the parking lot, the total number of parking spaces, and the number of remaining parking spaces. The parking information is distinguished by different colors for different parking lots and is consistent with the color of the guide light 2.

[0080] In this embodiment, the display body 11 includes at least two foldable screens 111 connected by hinges to allow the display body 11 to be folded in half and stored on the top surface of the base shell 12; it also includes a snap fastener 13 for fixing the folded display body 11; the snap fastener 13 includes a hook and a buckle, and the display body 11 is locked and fixed by the hook and the buckle after being folded in half;

[0081] The base shell 12 has a slot 121 on its top surface, which is horizontally positioned in the middle of the base shell 12. The bottom of the display screen body 11 is engaged with the slot 121 to achieve vertical insertion of the display screen body 11. The base shell 12 also has a slider seat 122 on its top surface, and the bottom of the display screen body 11 has a sliding groove 112. The slider seat 122 and the sliding groove 112 are connected by sliding rotation to achieve folding and flattening of the display screen body 11. The sliding groove 112 has a rotation groove 112a and a flattening groove 112b. After the display screen body 11 is disengaged from the slot 121, it moves along the rotation groove 112a to the flattening groove 112b to achieve switching between vertical and flattening states. It should be noted that when the two foldable screens 111 are unfolded into a vertical state, a latch is provided at the hinge to fix them and maintain the vertical state.

[0082] In this embodiment, a signal transmission cable (not shown in the figure) is connected between the two foldable screens 111, and the signal transmission cable is covered with a telescopic protective sleeve 113; the base shell 12 of the induction screen 1 includes a hollow bottom cavity with built-in counterweights to lower the center of gravity;

[0083] The roller assembly 14 is located at the bottom of the base shell 12; the two side walls of the base shell 12 are provided with mutually compatible hooks and hook holes; multiple guidance screens 1 are connected in a row and moved through the hooks and hook holes. It should be noted that traffic networks are subject to significant random changes. Configuring a movable and foldable traffic guidance screen 1 structure facilitates the rapid storage, movement, and deployment of the guidance screens 1, reducing maintenance costs. Furthermore, the ability to move multiple guidance screens 1 in a row via hooks and hook holes allows for easy movement by a single person, reducing manpower. The retractable protective sleeve 113 effectively protects the signal transmission cables, ensuring their transmission stability and simplifying the folding operation. For example, during peak traffic periods like holidays, staff can drag multiple guidance screens 1 in a row to temporary road nodes to expand the guidance coverage; in everyday scenarios, they can be folded for storage to reduce space requirements.

[0084] The guide lights 2 are installed on the corner shoulders 3 of the road nodes and extend along the road turning direction; each guide light 2 is communicatively connected to the guidance screen 1, synchronized with the color of the corresponding parking lot indicated on the guidance screen 1, and guides the vehicle driving direction in an intermittent flashing mode.

[0085] In this embodiment, the guide light 2 includes: a light body 21, a control unit (not shown in the figure), and a wireless communication module (not shown in the figure);

[0086] The control unit is connected to a wireless communication module to receive parking space status information and color coding instructions sent by the guidance screen 1;

[0087] The lamp body 21 is equipped with an RGB LED module 23, which switches the light emission color according to the color coding instruction and synchronizes with the parking lot color indicated by the guidance screen 1.

[0088] The intermittent flashing mode includes: flashing at a first frequency when the number of remaining berths is greater than a preset threshold; switching to a second frequency when the number of remaining berths is lower than the threshold; and turning off the lights when there are no remaining berths.

[0089] Different colors are used to distinguish different parking lots, eliminating the need for users to frequently operate their phones while driving. Simply observing the prompts on the guidance screen 1 and the guide lights 2 is sufficient to clearly identify the parking lot location and available spaces, allowing users to prepare for their journey in advance. This enables effective linkage between the guidance screen 1 and the navigation system, further enhancing parking convenience. It should be noted that current technology lacks a linkage mechanism with the parking lot guidance screen 1, preventing real-time display of parking space status and guidance information along the user's driving path. When there are two parking lots on the same route, adjacent guide lights 2 can be configured with different colors to correspond to different parking lots, flashing alternately according to the colors of the corresponding parking lots.

[0090] This embodiment constructs a multimodal guidance system through the collaborative work of guidance screen 1 and guide lights 2: (1) Guidance screen 1 distinguishes parking lots by color and combines key information such as directional arrows and remaining parking spaces to provide users with a macro-level route decision-making basis; (2) Guide lights 2 extend along the road turning points, with their colors consistent with the corresponding parking lots indicated by guidance screen 1, and enhance the visual guidance effect through intermittent flashing frequency. This linkage mode of "large screen global guidance + small light detailed guidance" enables users to quickly identify the direction of the target parking lot in complex road networks, reducing driving hesitation and route errors. Especially at night or in bad weather, light guidance can significantly improve driving safety.

[0091] In this embodiment, the guide light 2 further includes:

[0092] The photoelectric ranging sensor 22 is located on the side of the lamp body 21 and is used to detect the real-time distance between the vehicle and the guide light 2.

[0093] The control unit adjusts the headlight brightness according to the vehicle distance, and the relationship between the brightness value L and the distance d satisfies the formula:

[0094] L = L max ×e -k·d ;

[0095] Among them, L max d represents the maximum brightness, k is the attenuation coefficient, and d is the straight-line distance between the vehicle and guide light 2.

[0096] The brightness of the guide light 2 varies with the distance to the vehicle, which not only effectively saves energy but also avoids excessive light pollution and ensures driving safety.

[0097] Specifically, the guide light 2 has a built-in photoelectric distance sensor 22, such as model VL53L0X, and the control unit uses an STM32F103 microcontroller. Based on the vehicle distance d detected by the sensor, the LED brightness is dynamically adjusted by substituting it into the formula.

[0098] For example, setting: L max =1000 lux; k=0.5m -1 Therefore, when the vehicle is 0.5m away from the guide light (2d = 0.5m), the brightness value is: L = 1000 × e -0.5×0.5 ≈778 lux; When the vehicle is 1.5m away from the guide light (2d), the brightness value is: L = 1000 × e -0.5×1.5 ≈472 lux. The brightness increases when vehicles approach to enhance guidance and decreases when they move away to reduce light pollution and save energy.

[0099] The mobile device is equipped with a smart parking app or mini-program. Users connect to the cloud server via the mobile device to obtain parking space status information and navigation routes. The navigation route is generated based on the user's input destination, real-time traffic conditions, and the number of remaining parking spaces in the parking lot, and is linked with the guidance screen 1 and guide lights 2 to dynamically adjust the guidance information. The mobile device includes mobile phones, tablets, etc.

[0100] In this embodiment, the smart parking APP or mini-program includes:

[0101] The map interface module integrates third-party map resources and displays berth status data with a map background.

[0102] The positioning module obtains the user's real-time location and loads information about nearby parking spaces after user authorization.

[0103] The search module supports inputting road segments or business names as destinations and generating navigation routes by associating parking data.

[0104] The reservation module is linked to the parking lot barrier. After a user selects a reserved parking space, the barrier rises and locks the space until the user arrives or the time expires.

[0105] Smart parking apps or mini-programs can be configured with map integration, merchant association, and reservation functions to provide one-stop parking and surrounding service information, thereby improving the user experience for navigation users.

[0106] In this embodiment, the map interface module further includes:

[0107] The layered display function shows the real-time number and location of remaining parking spaces on the first layer, and overlays information on surrounding merchants and consumption data on the second layer.

[0108] The path planning algorithm calculates the shortest path P based on real-time traffic conditions.short and the congestion avoidance path P avoid The path weight W satisfies:

[0109] W = α·t + β·d + γ·s;

[0110] Where t is the estimated passage time, d is the distance, s is the number of remaining berths, and α, β, and γ are adjustable weighting coefficients.

[0111] The navigation routes generated on the mobile device are not only based on the user's input destination, but also dynamically adjusted by considering real-time traffic conditions, the number of remaining parking spaces in parking lots, and the status of guidance screen 1 / guide lights 2. For example, when the number of remaining parking spaces in a parking lot approaches zero, the system automatically guides the user to a nearby vacant parking lot and updates the color indicators on guidance screen 1 and switches the flashing mode of guide lights 2 to achieve a balanced distribution of traffic flow across the entire area. In addition, the route planning algorithm incorporates weighting factors (such as distance, time, and number of parking spaces) to calculate the optimal route, balancing efficiency and parking success rate, thus alleviating local congestion at its source.

[0112] Let's take parking lots A, B, and C as examples:

[0113] The weighting coefficients are set to α = 0.4 (time), β = 0.3 (distance), and γ = 0.3 (number of parking spaces); at this time, the real-time data is as follows:

[0114] Parking lot A (t = 15 min, d = 2.5 km, s = 2), parking lot B (t = 8 min, d = 3.8 km, s = 10), and parking lot C (t = 12 min, d = 3.0 km, s = 5). Then:

[0115] W A =0.4×15+0.3×2.5+0.3×2=6.0+0.75+0.6=7.35;

[0116] W B =0.4×8+0.3×3.8+0.3×10=3.2+1.14+3.0=7.34;

[0117] W C =0.4×12+0.3×3.0+0.3×5=4.8+0.9+1.5=7.20.

[0118] W c If the value is 7.20, then parking lot C is the preferred choice, as it achieves the best balance between time, distance, and number of parking spaces.

[0119] In this embodiment, the cloud server further includes:

[0120] The dynamic scheduling module calculates the optimal parking lot recommendation priority based on the number of remaining parking spaces in each parking lot and the road congestion index.

[0121] The priority score S i For the i-th parking lot, the following conditions must be met:

[0122]

[0123] Where, N i N represents the number of remaining berths. total T represents the total number of berths. i The estimated time from the current location to the parking lot is represented by w1 and w2, which are weighting coefficients.

[0124] The parking space navigation system in this area can identify the occupancy status of parking spaces in real time and quickly synchronize the parking space status information to the cloud server. Users can connect to the cloud server via their mobile devices to obtain accurate real-time parking space status, plan their parking strategies in a timely manner, effectively avoid unnecessary time wasted searching for parking spaces after arriving at the parking lot, and greatly improve parking efficiency.

[0125] Let's take parking lots A and B as examples:

[0126] Set parking lot A:N i =2, N total =50,T i =15min; Parking lot B:N i =10, N total =100, T i =8min; where the weighting coefficients w1 = 0.6 (remaining parking space weight) and w2 = 0.4 (time weight). The priority calculation is as follows:

[0127]

[0128] Because S B If the value is higher than 0.110, then parking lot B will be the preferred choice.

[0129] In this embodiment, the dynamic scheduling module is further configured with:

[0130] In emergency mode, when a sudden traffic incident is detected, the color coding of the guide lights 2 is reassigned, and the recommended priority of parking lots in the affected area is downgraded.

[0131] The emergency mode is triggered when the average vehicle speed V on a certain road segment in the real-time traffic data satisfies: V <V threshold And the duration exceeds a preset threshold. For example: set a threshold V. threshold=20km / h, the average vehicle speed V on a certain road section is less than 20km / h for 10 minutes. Users can know the availability and precise location of parking spaces in various parking lots in advance while driving. Combined with real-time traffic information, the system plans the optimal driving route for users, avoiding congested sections and improving the travel experience.

[0132] In a specific application, the above-described solution of the present invention provides a method for navigating a berth in a designated area, comprising the following steps:

[0133] S1: The parking management system collects the occupancy status of each parking space in real time and uploads it to the cloud server;

[0134] S2: Guidance screen 1 obtains the remaining parking space data from the cloud server, distinguishes parking lots by color coding, and displays the data dynamically;

[0135] S3: The mobile device receives the user's input destination and generates a navigation route by combining real-time traffic conditions and remaining parking spaces;

[0136] S4: Activate the guide lights 2 at the corresponding road nodes according to the navigation route, and guide the vehicle to drive by color synchronization and intermittent flashing;

[0137] S5: When a user selects a reserved parking space, the control of the parking space barrier is used to lock the space and start a countdown. The parking space is automatically released after the countdown expires.

[0138] This embodiment connects the guidance screen 1 to the cloud server, displaying real-time parking information including parking lot direction, total number of parking spaces, and number of remaining spaces. Different colors are used to distinguish different parking lots. Furthermore, the guide lights 2 are synchronized with the guidance screen 1, allowing users to intuitively follow the navigation route without frequently operating their phones; they can simply observe the guide lights 2. In addition, based on the user's input destination, real-time traffic conditions, and the number of remaining parking spaces, a navigation route is dynamically generated. Users can know the availability and precise location of parking spaces in each parking lot in advance while driving, improving the travel experience and significantly enhancing the real-time performance of parking navigation.
