Description

Technical Field

[0001] The present invention belongs to the technical field of berth navigation, and particularly relates to a regional berth navigation system and a navigation method thereof. Background Art

[0002] With the acceleration of urbanization and the sharp increase in the number of motor vehicles, intelligent parking technology, as an important solution to alleviate parking problems, has an increasingly expanding application scenario and market demand. Most of the existing intelligent parking systems rely on mobile applications (APPs) or mini-programs, and through functions such as electronic payment, order management, and berth query, the efficiency of parking management and the user experience have been improved. For example, users can view information such as the location of the parking lot and the charging standard in real time through the APP and complete the remote payment operation. However, the core function of the current intelligent parking system still focuses on the transaction link, lacking effective support for the path planning before parking and the dynamic navigation requirements of berths for users, and it is difficult to meet the actual needs of efficient parking in a complex urban traffic environment.

[0003] In the prior art, the Chinese patent document with the publication number CN105631523A proposed a smart parking lot system and method, which online reserves parking spaces through a terminal device and uses parking space occupancy piles and intelligent switches to control the locking and release of parking spaces, solving the technical problem of online reservation of parking spaces. However, this solution still has the following limitations: First, its core function focuses on parking space reservation and status control, and fails to solve the user's need to obtain the occupancy status of berths in real time during driving. Traditional intelligent parking APPs or mini-programs usually only display the total number of berths and cannot dynamically update the occupancy information of individual parking spaces, resulting in users still having to blindly search for available parking spaces after arriving at the parking lot; Second, the prior art lacks a linkage mechanism with the parking lot induction screen and cannot display the berth status and guiding information in real time through the induction screen in the user's driving route, making it difficult for users to plan the optimal driving route in advance. For example, users may be forced to turn to other parking lots midway due to the inability to predict the remaining number of parking spaces in the target parking lot, resulting in waste of time and energy.

[0004] In summary, although the existing intelligent parking technology is relatively mature in terms of payment and order management, there are still significant deficiencies in the real-time nature of berth navigation, dynamic path planning, and the linkage with induction facilities. Especially in urban areas with dense traffic flow, users urgently need a solution that can real-time sense the berth status, dynamically associate with the induction screen, and generate the optimal navigation path to improve parking efficiency and reduce traffic congestion. Therefore, aiming at the defects of the prior art, it is urgent to propose an innovative regional berth navigation system and method, which realizes the full-process optimization from the user's driving decision to the completion of parking by integrating berth status perception, multi-modal guidance, and intelligent path planning. Summary of the Invention

[0005] In view of the problems in the related art, the present invention provides a regional berth navigation system and its navigation method to solve the deficiencies of the existing intelligent parking technology in aspects such as the real-time performance of berth navigation, dynamic path planning, and linkage with induction facilities.

[0006] The technical solution of the present invention is implemented as follows: A regional berth navigation system includes:

[0007] A cloud server, a parking lot management system, an induction screen, guiding lights, and a mobile terminal;

[0008] There are multiple roads within the navigation area, and the intersections of the roads are road nodes. The induction screen and guiding lights are provided near each road node; each road extends to the corresponding parking lot, and each parking lot contains multiple berths;

[0009] The parking lot management system is set in each parking lot, used to identify the occupancy status of the berths in real time, and synchronize the berth status information to the cloud server;

[0010] The induction screen includes a display screen main body and a base shell. The display screen main body can be folded and placed on the top of the base shell; the induction screen is communicatively connected to the cloud server and is used to display parking information, including the direction of the parking lot, the total number of berths, and the remaining number of berths; the parking information distinguishes different parking lots by different colors and is consistent with the color of the guiding lights;

[0011] The guiding lights are set on the corner road shoulders of the road nodes and are distributed along the extension of the road turn; each guiding light is communicatively connected to the induction screen, synchronized with the color of the corresponding parking lot marked by the induction screen, and guides the driving direction of the vehicle in an intermittent flashing mode;

[0012] The mobile terminal is installed with a smart parking APP or a small program. The user connects to the cloud server through the mobile terminal to obtain the berth status information and the navigation path; the navigation path is generated based on the destination input by the user, the real-time road conditions, and the remaining number of berths in the parking lot, and is linked with the induction screen and the guiding lights to dynamically adjust the guiding information.

[0013] Through the communicative connection between the induction screen and the cloud server, the present invention can display parking information such as the direction of the parking lot, the total number of berths, and the remaining number of berths in real time, and distinguish different parking lots by different colors. Coupled with the synchronization of the guiding lights and the induction screen, the user does not need to operate the mobile phone frequently and can directly drive along the navigation route only by observing the guiding lights. In addition, based on the destination input by the user, the real-time road conditions, and the remaining number of berths in the parking lot, a navigation path is dynamically generated. The user can know in advance the remaining berth quantity and the precise location of each parking lot during the driving process, improving the travel experience and significantly enhancing the real-time performance of berth navigation.

[0014] As a further improvement of the above solution, the main display screen includes at least two foldable screens, which are connected by hinges to allow the main display screen to be folded in half and stored on the top surface of the base case; it also includes a clamping fastener for fixing the folded main display screen; the clamping fastener includes a hanging ear and a buckle, and the main display screen is locked and fixed by the hanging ear and the buckle after being folded in half;

[0015] A slot is provided on the top surface of the base case. The slot is horizontally arranged in the middle of the base case, and the bottom of the main display screen is clamped on the slot to achieve vertical insertion and fixation of the main display screen; a slider seat is also provided on the top surface of the base case, and a chute is provided at the bottom of the main display screen. Through the sliding and rotating connection between the slider seat and the chute, the main display screen can be folded and laid flat; the chute is provided with a rotating slot and a flat-laying slot. After the main display screen is separated from the slot, it moves along the rotating slot to the flat-laying slot to realize the switching between the vertical state and the flat-laying state.

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

[0017] A roller group is arranged at the bottom of the base case; hooks and hook holes that match each other are provided on both side walls of the base case; multiple induction screens are connected by the hooks and the hook holes to move in a row. It should be noted that the changes in the traffic network are relatively random. Configuring a movable and foldable structure for the driving induction screen is beneficial to the rapid storage, movement and deployment of the induction screen, reducing the maintenance cost; in addition, multiple induction screens are connected by hooks and hook holes to move in a row, which is convenient for a single person to move a row of induction screens, reducing the manpower; and the setting of the telescopic protective sleeve can effectively protect the signal transmission cable, ensure its transmission stability, and simplify the folding operation. For example, when the traffic flow surges during holidays, the staff can drag multiple induction screens in a row to temporary road nodes to expand the guiding coverage; in daily scenarios, they can be folded and stored to reduce the occupied space.

[0018] As a further improvement of the above solution, the guiding lamp includes: a lamp body, a control unit and a wireless communication module;

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

[0020] The lamp body is provided with an RGB LED module, which switches the emitting color according to the color coding instructions and synchronizes with the corresponding color marked on the induction screen;

[0021] The intermittent flashing mode includes: when the remaining number of parking spaces is greater than the preset threshold, it flashes at the first frequency; when the remaining number of parking spaces is lower than the threshold, it switches to the second frequency to flash; when there is no remaining parking space, the light is turned off.

[0022] Distinguish different parking lots by different colors, so that users do not need to operate the mobile phone frequently during driving. They only need to observe the prompts of the induction screen and guiding lights to clearly know the location of the parking lot and the remaining berth situation, make preparations for driving in advance, realize the effective linkage between the induction screen and the navigation system, and further improve the parking convenience. It should be noted that the existing technology lacks a linkage mechanism with the parking lot induction screen and cannot display the berth status and guiding information in real time through the induction screen in the user's driving route. The present invention constructs a multi-modal guiding system through the collaborative work of the induction screen and guiding lights: (1) The induction screen distinguishes parking lots by color and provides users with a macro path decision-making basis by combining key information such as direction arrows and the number of remaining berths; (2) The guiding lights are distributed along the road turning extension, and their colors are consistent with the corresponding parking lots marked on the induction screen, and the visual guiding effect is strengthened through the intermittent flashing frequency. This "large screen global guidance + small light detail guidance" linkage mode enables users to quickly identify the direction of the target parking lot in a complex road network, 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 of the above solution, the guiding light further includes:

[0024] An optoelectronic ranging sensor, which is arranged on the side of the lamp body and is used to detect the real-time distance between the vehicle and the guiding light;

[0025] The control unit adjusts the light 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] where L max is the maximum brightness, k is the attenuation coefficient, and d is the straight-line distance between the vehicle and the guiding light.

[0028] Setting the light brightness of the guiding light to change with the vehicle distance can not only effectively save energy, but also avoid excessive light pollution and ensure driving safety.

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

[0030] A map interface module, which integrates third-party map resources and displays berth status data with the map as the background;

[0031] A positioning module, which obtains the real-time position and loads the surrounding berth information after the user authorizes;

[0032] A search module, which supports inputting a road section or merchant name as the destination, associating parking lot data to generate a navigation route;

[0033] The reservation module is linked to the vehicle stopper in the parking lot. After the user selects a reserved parking space, the vehicle stopper rises and locks the parking space until the user arrives or the time limit is exceeded.

[0034] The smart parking APP or mini-program is configured with map integration, merchant association, and reservation functions, providing one-stop parking and surrounding service information to improve the user experience of navigation users.

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

[0036] The hierarchical display function, where the first layer displays the real-time remaining berth quantity and location, and the second layer superimposes the surrounding merchant information and consumption data;

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

[0038] W = α·t + β·d + γ·s;

[0039] where t is the estimated travel time, d is the distance, s is the remaining berth quantity, and α, β, and γ are adjustable weight coefficients.

[0040] The navigation path generated by the mobile device is not only based on the destination input by the user, but also dynamically adjusted based on the real-time road conditions, the remaining berth quantity in the parking lot, and the status of the induction screen / guide lights. For example, when the remaining berth in a certain parking lot approaches zero, the system automatically guides the user to a neighboring idle parking lot, and updates the color identification through the induction screen and switches the flashing mode of the guide lights to achieve an even distribution of vehicle flow in the entire area. In addition, the path planning algorithm introduces weight factors (such as distance, time, and number of parking spaces) to calculate the optimal path, taking into account both efficiency and parking success rate, and alleviating local congestion from the source.

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

[0042] The dynamic scheduling module calculates the optimal parking lot recommendation priority based on the remaining berth quantity in each parking lot and the road congestion index;

[0043] The priority score S i for the i-th parking lot satisfies:

[0044]

[0045] where N i is the remaining number of berths, N total is the total number of berths, T i is the estimated time from the current location to the parking lot, and w1, w2 are weight coefficients.

[0046] This regional berth navigation system can identify the occupied status of berths in real time and quickly synchronize the berth status information to the cloud server. Users can connect to the cloud server through the mobile terminal, obtain the accurate real-time status of berths, plan parking strategies in a timely manner, effectively avoid the waste of unnecessary berth searching time after arriving at the parking lot, and greatly improve the parking efficiency.

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

[0048] An emergency mode, when a sudden traffic event is detected, reassign the color coding of the guiding lights and downgrade the recommended priority of the parking lots in the affected area;

[0049] The triggering condition of the emergency mode is: the average vehicle speed V of a certain road section in the real-time traffic condition data satisfies: V < V threshold and the duration exceeds a preset threshold. Users can know in advance the remaining berth quantity and accurate location of each parking lot during the driving process. Combining with the real-time traffic condition information, the system plans the optimal driving route for users, avoids congested road sections, and improves the travel experience.

[0050] A regional berth navigation method is applied to a regional berth navigation system as described above, including the following steps:

[0051] S1: Real-time collect the occupied status of each berth through the parking lot management system and upload it to the cloud server;

[0052] S2: The induction screen obtains the remaining berth data from the cloud server, distinguishes the parking lots by color coding and dynamically displays them;

[0053] S3: The mobile terminal receives the destination input by the user, and generates a navigation route in combination with the real-time traffic condition and the remaining berths;

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

[0055] S5: When the user selects to reserve a berth, control the vehicle stopper to lock the berth and start a countdown, and automatically release the berth after the timeout.

[0056] Beneficial effects:

[0057] (1) Enhance the linkage with the induction facilities: The induction screen is communicatively connected to the cloud server, and can display parking information such as the direction of the parking lot, the total number of berths and the remaining berth quantity in real time, and distinguish different parking lots by different colors, so that users do not need to operate the mobile phone frequently during the driving process. Just observing the prompts of the induction screen and the guiding lights, they can clarify the location of the parking lot and the remaining berth situation, make preparations for driving in advance, realize the effective linkage between the induction screen and the navigation system, and further improve the parking convenience.

[0058] (2) Optimize the path planning ability: Due to the lack of a linkage mechanism with the parking lot induction screen in the existing technology, it is difficult for users to plan the optimal driving route in advance. However, the navigation path of this system is dynamically generated based on the destination input by the user, real-time traffic conditions, and the remaining berth quantity in the parking lot. During the driving process, users can know in advance the remaining berth quantity and the precise location of each parking lot. Combining with the real-time traffic condition information, the system plans the optimal driving route for users, avoiding congested sections and enhancing the travel experience.

[0059] (3) Significantly improve the real-time performance of berth navigation: Traditional smart parking APPs or mini-programs only display the total number of berths and cannot dynamically update the occupancy information of individual parking spaces, resulting in users having to blindly search for available parking spaces after arriving at the parking lot. The berth navigation system in this area can identify the occupancy status of berths in real time and quickly synchronize the berth status information to the cloud server. By connecting to the cloud server through the mobile terminal, users can obtain the precise real-time status of berths, plan the parking strategy in a timely manner, effectively avoid the waste of unnecessary parking space searching time after arriving at the parking lot, and greatly improve the parking efficiency.

[0074] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0075] Embodiment:

[0076] As Figure 1-6 shown, a regional berth navigation system includes:

[0077] A cloud server, a parking lot management system, an induction screen 1, a guiding light 2 and a mobile terminal; there are multiple roads in the navigation area, the intersections of the roads are road nodes, and the induction screen 1 and the guiding light 2 are arranged near each road node; each road extends to the corresponding parking lot, and each parking lot includes multiple berths.

[0078] The parking lot management system is arranged in each parking lot, used to identify the occupancy status of the berths in real time, and synchronize the berth status information to the cloud server;

[0079] The induction screen 1 includes a display screen main body 11 and a base shell 12, and the display screen main body 11 can be folded and placed on the top of the base shell 12; the induction screen 1 is communicatively connected to the cloud server, used to display parking information, including the direction of the parking lot, the total number of berths and the remaining number of berths; the parking information distinguishes different parking lots through different colors and is consistent with the color of the guiding light 2.

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

[0081] The top surface of the base shell 12 is provided with a slot 121, which is horizontally arranged in the middle of the base shell 12. The bottom of the display screen main body 11 is clamped on the slot 121 to realize the vertical insertion and fixation of the display screen main body 11. The top surface of the base shell 12 is also provided with a slider seat 122, and the bottom of the display screen main body 11 is provided with a sliding groove 112. Through the sliding and rotating connection between the slider seat 122 and the sliding groove 112, the display screen main body 11 is folded and laid flat. The sliding groove 112 is provided with a rotating groove 112a and a flat laying groove 112b. After the display screen main body 11 is separated from the slot 121, it moves along the rotating groove 112a to the flat laying groove 112b to realize the switching between the vertical state and the flat laying state. It should be noted that when the two foldable screens 111 are unfolded into a vertical state, a lock is provided at the hinge and fixed by the lock to maintain the vertical state.

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

[0083] The roller group 14 is arranged at the bottom of the base shell 12. Hook and hook holes that match each other are provided on both side walls of the base shell 12. A plurality of induction screens 1 are connected by hooks and hook holes to move in a row. It should be noted that the traffic network changes randomly. Configuring a structure of a movable and foldable driving induction screen 1 is beneficial to the quick storage, movement and deployment of the induction screen 1, and reduces the maintenance cost. In addition, a plurality of induction screens 1 are connected by hooks and hook holes to move in a row, which is convenient for a single person to move a row of induction screens 1 and reduces the manpower. The setting of the telescopic protective sleeve 113 can effectively protect the signal transmission cable, ensure its transmission stability, and simplify the folding operation. For example, when the traffic flow surges during holidays, the staff can drag a plurality of induction screens 1 in a row to temporary road nodes to expand the guiding coverage. In daily scenarios, they can be folded and stored to reduce the occupied space.

[0084] The guiding lights 2 are arranged on the corner road shoulders 3 of the road nodes and are distributed along the road turning. Each guiding light 2 is in communication connection with the induction screen 1, synchronizes with the color of the corresponding parking lot marked on the induction screen 1, and guides the driving direction of the vehicle in an intermittent flashing mode.

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

[0086] The control unit is connected to the wireless communication module and receives the parking lot berth status information and color coding instructions sent by the induction screen 1;

[0087] The lamp body 21 is provided with an RGB LED module 23, which switches the emitting color according to the color coding instruction and synchronizes with the corresponding color of the parking lot marked on the induction screen 1.

[0088] The intermittent flashing mode includes: when the remaining parking spaces are greater than the preset threshold, it flashes at the first frequency; when the remaining parking spaces are lower than the threshold, it switches to the second frequency for flashing; when there are no remaining parking spaces, the light is turned off.

[0089] By distinguishing different parking lots with different colors, users do not need to operate their mobile phones frequently during driving. They only need to observe the prompts of the induction screen 1 and the guiding lamp 2 to clearly know the location of the parking lot and the remaining parking spaces, make preparations in advance for driving, realize the effective linkage between the induction screen 1 and the navigation system, and further improve the parking convenience. It should be noted that the prior art lacks a linkage mechanism with the parking lot induction screen 1 and cannot display the berth status and guiding information in real time through the induction screen 1 in the user's driving route. When there are two parking lots on the same route, adjacent guiding lamps 2 can be configured with different colors corresponding to different parking lots, and they alternately flash the colors of the corresponding parking lots.

[0090] In this embodiment, through the collaborative work of the induction screen 1 and the guiding lamp 2, a multi-modal guiding system is constructed: (1) The induction screen 1 distinguishes parking lots by color and provides users with a macroscopic path decision-making basis by combining key information such as direction arrows and the remaining number of parking spaces; (2) The guiding lamps 2 are distributed along the road turning extension, and their colors are the same as those of the corresponding parking lots marked on the induction screen 1, and the visual guiding effect is enhanced through the intermittent flashing frequency. This "large screen global guidance + small lamp detail guidance" linkage mode enables users to quickly identify the direction of the target parking lot in a complex road network, reduce driving hesitation and path errors. Especially at night or in bad weather, the light guidance can significantly improve driving safety.

[0091] In this embodiment, the guiding lamp 2 further includes:

[0092] An optoelectronic ranging sensor 22 is arranged on the side of the lamp body 21 and is used to detect the real-time distance between the vehicle and the guiding lamp 2.

[0093] The control unit adjusts the light 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] where, L max is the maximum brightness, k is the attenuation coefficient, and d is the straight-line distance between the vehicle and the guiding lamp 2.

[0096] Setting the light brightness of the guiding lamp 2 to change with the vehicle distance can not only effectively save energy, but also avoid excessive light pollution and ensure driving safety.

[0097] Specifically, the guiding lamp 2 is internally provided with a photoelectric ranging sensor 22, such as model VL53L0X. The control unit uses an STM32F103 microcontroller, and according to the vehicle distance d detected by the sensor, the LED brightness is dynamically adjusted by substituting it into the formula.

[0098] For example, set: max L = 1000 lux; k = 0.5 m -1 , then when the vehicle distance from the guiding lamp 2 is d = 0.5 m, the brightness value: L = 1000 × e -0.5×0.5 ≈ 778 lux; when the vehicle distance from the guiding lamp 2 is d = 1.5 m, the brightness value: L = 1000 × e -0.5×1.5 ≈ 472 lux. When the vehicle approaches, the brightness increases to strengthen the guidance. When it moves away, the brightness decreases to reduce light pollution and save energy consumption at the same time.

[0099] The mobile terminal is installed with a smart parking APP or applet. The user connects to the cloud server through the mobile terminal to obtain the berth status information and navigation path; the navigation path is generated based on the destination input by the user, the real-time road conditions, and the remaining berth quantity in the parking lot, and is linked with the induction screen 1 and the guiding lamp 2 to dynamically adjust the guiding information. The mobile terminal includes a mobile phone, a tablet, etc.

[0100] In this embodiment, the smart parking APP or applet includes:

[0101] A map interface module that integrates third-party map resources and displays the berth status data with the map as the background;

[0102] A positioning module that obtains the real-time position and loads the surrounding berth information after the user authorizes;

[0103] A search module that supports inputting a road section or a merchant name as the destination and generates a navigation route by associating with the parking lot data;

[0104] A reservation module that is linked with the parking lot blocker. After the user selects a reserved parking space, the blocker rises and locks the parking space until the user arrives or times out.

[0105] The smart parking APP or applet configures map integration, merchant association, and reservation functions, provides one-stop parking and surrounding service information, and improves the usage experience of navigation users.

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

[0107] A hierarchical display function. The first layer displays the real-time remaining berth quantity and position, and the second layer superimposes the surrounding merchant information and consumption data;

[0108] A path planning algorithm that calculates the shortest path P according to the real-time road conditionsshort 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 travel time, d is the distance, s is the remaining number of berths, and α, β, and γ are adjustable weight coefficients.

[0111] The navigation path generated by the mobile terminal is not only based on the destination input by the user, but also dynamically adjusted in combination with real-time road conditions, the remaining number of berths in the parking lot, and the status of the induction screen 1 / guide light 2. For example, when the remaining number of berths in a certain parking lot approaches zero, the system automatically guides the user to a neighboring idle parking lot, and updates the color identification through the induction screen 1 and switches the flashing mode of the guide light 2 to achieve balanced distribution of traffic flow in the entire area. In addition, the path planning algorithm introduces weight factors (such as distance, time, and number of parking spaces) to calculate the optimal path, taking into account both efficiency and parking success rate, and alleviating local congestion from the source.

[0112] Taking parking lots A, B, and C as examples:

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

[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), 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 = 7.20 is the smallest, so parking lot C is preferentially recommended, which achieves the best balance among time, distance, and the number of parking spaces.

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

[0120] The dynamic scheduling module calculates the recommended priority of the optimal parking lot according to the remaining berth numbers of each parking lot and the road congestion index;

[0121] The priority score S i For the i-th parking lot, it satisfies:

[0122]

[0123] where, N i is the remaining berth number, N total is the total berth number, T i is the estimated time from the current location to the parking lot, and w1, w2 are weight coefficients.

[0124] The berth navigation system in this area can identify the occupied status of berths in real time and quickly synchronize the berth status information to the cloud server. Users can connect to the cloud server through the mobile terminal to obtain the accurate real-time status of berths, plan parking strategies in a timely manner, effectively avoid the waste of meaningless berth searching time after arriving at the parking lot, and greatly improve the parking efficiency.

[0125] Taking parking lots A and B as examples:

[0126] Set parking lot A: N i = 2, N total = 50, T i = 15 min; parking lot B: N i = 10, N total = 100, T i = 8 min; where, the weight coefficient w1 = 0.6 (weight of remaining parking spaces), w2 = 0.4 (weight of time). Then the priority is calculated as follows:

[0127]

[0128] Since S B = 0.110 is higher, parking lot B is recommended first.

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

[0130] An emergency mode. When a sudden traffic event is detected, the color coding of the guiding lights 2 is reallocated, and the recommended priority of the parking lots in the affected area is downgraded;

[0131] The triggering condition of the emergency mode is that the average vehicle speed V of a certain road section in the real-time traffic condition data satisfies: V < V threshold , and the duration exceeds a preset threshold. For example: set the threshold V threshold= 20 km / h, the average vehicle speed on a certain section is V < 20 km / h for 10 minutes. During the driving process, users can know in advance the remaining berths and accurate locations of each parking lot. Combining with the real-time traffic conditions information, the system plans the optimal driving route for users, avoids congested sections, and improves the travel experience.

[0132] Through the above solution of the present invention, in a specific application: A regional berth navigation method includes the following steps:

[0133] S1: Real-time collect the occupancy status of each berth through the parking lot management system and upload it to the cloud server;

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

[0135] S3: The mobile terminal receives the destination input by the user, and generates a navigation route in combination with the real-time traffic conditions and the remaining berths;

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

[0137] S5: When the user selects to reserve a berth, control the vehicle stopper to lock the berth and start a countdown, and automatically release the berth after the timeout.

[0138] In this embodiment, the induction screen 1 is communicatively connected to the cloud server, and parking information such as the direction of the parking lot, the total number of berths, and the remaining number of berths is displayed in real time. Different parking lots are distinguished by different colors. In addition, the guiding lights 2 are synchronized with the induction screen 1, so that users do not need to frequently operate the mobile phone, and only need to observe the guiding lights 2 to drive intuitively according to the navigation route. In addition, based on the destination input by the user, the real-time traffic conditions, and the remaining number of berths in the parking lot, a navigation path is dynamically generated. During the driving process, users can know in advance the remaining berths and accurate locations of each parking lot, improve the travel experience, and significantly improve the real-time performance of berth navigation.
