Description

Technical Field

[0001] This invention relates to the field of parking garage technology for storing multiple vehicles, and more particularly to a multi-level parking garage system built at urban intersections. Background Technology

[0002] The problem of nowhere to park vehicles is an inevitable result of urban economic and transportation development to a certain stage. Multi-level parking systems have been developing for nearly 30 to 40 years and have achieved success both technically and experientially. However, these multi-level parking systems are generally installed in parking lots or residential areas, with a single purpose and cannot significantly contribute to urban traffic flow.

[0003] For example, CN108412268A discloses a three-dimensional parking garage balancing device and a three-dimensional parking garage. In current three-dimensional parking garages, there is an imbalance problem when the parking platform of the car rises or falls when the vehicle enters or leaves. That is, when the vehicle enters or leaves the parking platform, the platform will shake, which affects the parking experience.

[0004] Another typical example is the prior art disclosed in CN108756391B, which describes a multi-level parking garage access system and a multi-level parking garage itself. The growth rate of motor vehicle ownership far exceeds the growth rate of parking infrastructure, making parking difficulties a common phenomenon in cities. Mechanical multi-level parking garages are an important way to solve urban static traffic problems. However, existing multi-level parking garages are not very convenient for car entry and exit.

[0005] Let's look at the prior art disclosed in CN107435453B, which discloses a trackless automated parking garage and a method for storing and retrieving vehicles without having to avoid obstacles. The existing obstacle-avoidance technology relies on three systems: lifting motion, rotational motion, and horizontal transportation. These three systems are attached to the track as a whole with the garage frame. Especially during the horizontal movement, the stability is poor because it is a multi-point articulated mechanism and has no other attachments.

[0006] Meanwhile, existing technologies also have the following problems: During peak hours, the vehicle exit order often does not consider the length of parking time, resulting in some vehicles with longer parking times being unable to exit in time, occupying parking resources and leading to low parking lot resource utilization efficiency. During the vehicle exit process, the scheduling system fails to effectively consider the step distance from the parking space to the exit station, causing vehicles to be delayed in exiting even if the parking space is close to the exit station, due to waiting for other vehicles to be scheduled. The scheduling algorithms of existing automated parking systems are usually relatively simple and cannot dynamically adjust the vehicle exit priority based on parking time and the number of steps per parking space, resulting in an unreasonable exit order during the vehicle scheduling process, which is especially inefficient when the demand for exiting is high.

[0007] This invention addresses common problems in the field, such as the inability to fine-tune parking positions, the inability to adjust vehicle positions, poor vehicle stability, high risk of tipping over, inability to guide vehicles, poor garage interaction performance, cumbersome vehicle entry and exit processes, complex vehicle retrieval processes, low intelligence, and lack of dynamic scheduling and priority management. Summary of the Invention

[0008] The purpose of this invention is to address the shortcomings of current systems by proposing a multi-level parking garage system based on urban intersections.

[0009] To overcome the shortcomings of the prior art, the present invention adopts the following technical solution:

[0010] The automated parking system includes a server, a parking frame, and at least two parking spaces mounted on the parking frame. The system further includes a parking space stabilization module, a parking space conversion module, an intelligent analysis module, and a guidance and interaction module, wherein the parking space stabilization module, the parking space conversion module, and the guidance and interaction module are respectively connected to the server.

[0011] The parking space stabilization module is used to collect the position of vehicles entering the parking space, evaluate the position of the vehicles based on the collected data, and trigger the timing of the parking time of the parked vehicles. The data sampling module collects the parking time of each parking space and the number of rotation steps from the parking space to the exit station. The intelligent analysis module analyzes and controls the parking status of the garage rack based on the parking time of each parking space and the number of rotation steps from the parking space to the exit station collected by the data collection module. The parking space conversion module is used to rotate the garage rack. The guidance interaction module is used to guide vehicles that are about to enter the garage.

[0012] The parking space stabilization module is installed in at least two parking spaces. The parking space stabilization module includes a timer, a parking detection unit, a position evaluation unit, and a position adjustment unit. The parking detection unit is used to collect the tension data of the vehicle's parking position in the parking space. The position evaluation unit evaluates the current parking position of the vehicle based on the tension data of the vehicle's parking position detected by the parking detection unit to form an evaluation result. The position adjustment unit adjusts the position of the vehicle's wheels based on the evaluation result to maintain the balance of the vehicle's position in the parking space and triggers the timer to count the parking time of each parking space.

[0013] Optionally, the parking space conversion module includes an inbound workstation, an outbound workstation, at least two parking space conversion units, and a location recognition unit. The parking space conversion unit is used to convert the location of the parking space, and the location recognition unit is used to recognize the location of the inbound workstation and the outbound workstation, respectively.

[0014] The parking space conversion unit includes a first conversion chain, a second conversion chain, a first sliding seat, a second sliding seat, a first sliding drive mechanism, and a second sliding drive mechanism. The first sliding seat is connected to the first conversion chain, the second sliding seat is connected to the second conversion chain, the first sliding drive mechanism is disposed on the first sliding seat, and the second sliding drive mechanism is disposed on the second sliding seat.

[0015] The two ends of the parking space are connected to the first sliding seat and the second sliding seat, respectively.

[0016] Optionally, the parking detection unit includes a detection plate, a data storage device, at least one pressure detection element, and a tensioning member. The detection plate is disposed in the parking space and detects the vehicle entering the parking space. At least one pressure detection element is evenly distributed on the detection plate. The data storage device is used to store the pressure data collected by at least one pressure detection element and the tensioning data detected by the tensioning member.

[0017] When the vehicle enters the parking space, the pressure detection element is squeezed.

[0018] Optionally, the pulling member includes at least four pulling ropes and at least four tension sensors, with the at least four tension sensors respectively disposed on the at least four pulling ropes to collect the tension data of the vehicle parked in the parking space;

[0019] At least four pull ropes are symmetrically arranged at the outer edge of the detection pressure plate.

[0020] Optionally, the position evaluation unit acquires the tension data of the vehicle's parking position in the parking space collected by the parking detection unit, and calculates the vehicle's current parking balance index Balance according to the following formula:

[0021] Balance=(F1·k1+F2·k2)-(F3·k1+F4·k2);

[0022] In the formula, F1, F2, F3 and F4 are the real-time tension data of the four pulling ropes, and k1 and k2 are the corresponding sensitivity coefficients, whose values ​​are obtained based on empirical values.

[0023] If the value of the parking balance index Balance is less than or equal to the set evaluation threshold Range, it means that the vehicle is in a balanced position in the parking space, and the parking space timer is triggered to count the parking time.

[0024] Optionally, the data acquisition module includes a parking time acquisition unit and a position sensing unit. The parking time acquisition unit acquires the parking time of each parking space, and the position sensing unit acquires the number of rotation steps of the parked vehicle from the parking space to the exit workstation.

[0025] The position sensing unit includes a position recognition probe and at least two position markers. The position recognition probe is used to identify the position of the at least two position markers. The at least two position markers mark at least two parking spaces respectively. The position recognition probe is set on the outbound workstation and identifies the position markers on the parking spaces.

[0026] The parking time acquisition unit calls the parking time timing data from the timer.

[0027] Optionally, the position adjustment unit is installed in the parking space and adjusts the parking position of the vehicle. The position adjustment unit includes a lifting component and an adjusting component. The lifting component is used to adjust the height of the adjusting component, and the adjusting component is used to adjust the position of the vehicle.

[0028] The lifting component includes a lifting rod, a lifting drive mechanism, and a lifting detection component. The lifting detection component is used to detect the lifting height of the lifting rod. One end of the lifting rod is connected to the adjusting component, and the other end of the lifting rod is driven to connect to the lifting drive mechanism to form a lifting part. The lifting part is disposed on the detection pressure plate.

[0029] Optionally, the intelligent analysis module calculates the priority index of each parking scheme based on the parking time of each parking space and the number of rotation steps from a parking space with a vehicle to the exit workstation, as collected by the data acquisition module:

[0030]

[0031] In the formula, N is the number of parking spaces in the garage rack, and priorityi is the i-th parking scheme;

[0032] Choose the state plan with the highest priority index from the M docking plans as the execution plan;

[0033] Among them, the parking status is the state where an empty parking space is facing the entry station, and the number of parking schemes M is equal to the number of empty parking spaces in the garage rack;

[0034] Each time a vehicle enters or exits, the intelligent analysis module is triggered to perform calculations, and the parking space conversion module is triggered to execute the selected scheme.

[0035] Optionally, the guidance and interaction module includes a guidance unit and an interaction unit. The guidance unit is used to guide the driver who drives into the parking space, and the interaction unit is used to interact with the driver to perform parking or retrieval operations on the vehicle driven by the driver.

[0036] Optionally, when the driver or passenger needs to retrieve the vehicle, they can interact with the interaction unit via the user terminal. After verifying the identity of the user terminal, the interaction unit can trigger the rotation of the parking space corresponding to their vehicle, so that the parking space is rotated to the exit workstation.

[0037] The beneficial effects achieved by this invention are:

[0038] 1. The parking space stabilization module stabilizes the parking space, effectively improving the safety of vehicle parking and preventing vehicles from tipping over during parking;

[0039] 2. By guiding the interaction of the vehicle parking and retrieval process through the interactive module, the parking and retrieval process can be simplified, reducing the labor intensity of drivers and passengers and enabling them to obtain the best parking comfort.

[0040] 3. Through the cooperation of the position adjustment unit and the position evaluation unit, the position adjustment unit can trigger the adjustment of the vehicle based on the evaluation result of the position evaluation unit, so as to improve the safety and reliability of vehicle storage in the garage;

[0041] 4. Through the cooperation of the guidance unit and the interaction unit, the system enables drivers and passengers to achieve the best parking comfort, while also taking into account the level of intelligence in human-computer interaction. This gives the entire system the advantages of convenient vehicle guidance, good garage interaction performance, and simple vehicle storage and retrieval process.

[0042] 5. Through the cooperation of the intelligent analysis module and the data acquisition module, the parking spaces in the garage rack can be precisely controlled, ensuring that the entire system has the advantages of strong dynamic control capability, high intelligence, reliable priority management, and convenient and comfortable parking and retrieval.

[0055] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can understand the advantages and effects of the present invention from the content disclosed in this specification. The present invention can be implemented or applied through other different specific embodiments, and various details in this specification can also be modified and changed based on different viewpoints and applications without departing from the spirit of the present invention. Furthermore, the accompanying drawings of the present invention are for simple illustrative purposes only and are not depictions of actual dimensions; this is stated beforehand. The following embodiments will further describe the relevant technical content of the present invention in detail, but the disclosed content is not intended to limit the scope of protection of the present invention.

[0056] Example 1: According to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, this embodiment provides a multi-level parking garage system based on urban intersections. The multi-level parking garage system includes a server, a parking garage frame, and at least two parking spaces installed on the parking garage frame. The multi-level parking garage system also includes a parking space stabilization module, a parking space conversion module, an intelligent analysis module, and a guidance interaction module. The parking space stabilization module, the parking space conversion module, and the guidance interaction module are respectively connected to the server, and the intermediate data and process data of the parking space stabilization module, the parking space conversion module, the intelligent analysis module, and the guidance interaction module are stored in the database of the server for querying or retrieval.

[0057] The parking space stabilization module is used to collect the position of vehicles entering the parking space, evaluate the position of the vehicles based on the collected data, and trigger the timing of the parking time of the parked vehicles. The data sampling module collects the parking time of each parking space and the number of rotation steps from the parking space to the exit station. The intelligent analysis module analyzes and controls the parking status of the garage rack based on the parking time of each parking space and the number of rotation steps from the parking space to the exit station collected by the data collection module. The parking space conversion module is used to rotate the garage rack. The guidance interaction module is used to guide vehicles that are about to enter the garage.

[0058] The automated parking system also includes a central processing unit, which is connected to the parking space stabilization module, the parking space conversion module, and the guidance and interaction module for centralized control, thereby improving the intelligence of the entire system and enabling the entire system to operate autonomously.

[0059] When vehicle 11 needs to park in a parking space, it will enter the area of ​​the multi-level parking garage and guide the driver and passengers through the interactive guidance module.

[0060] Once vehicle 11 is parked in the parking space, the parking space stabilization module stabilizes vehicle 11 to improve its parking stability. The parking space stabilization module includes a timer, a parking detection unit, a position evaluation unit, and a position adjustment unit. The parking detection unit collects tension data of the vehicle's parking position within the parking space. The position evaluation unit evaluates the vehicle's current parking position based on the tension data detected by the parking detection unit, generating an evaluation result. The position adjustment unit adjusts the position of the vehicle's wheels based on the evaluation result to maintain the vehicle's balance within the parking space and triggers the timer to record the parking time for each space. In this embodiment, when multiple different vehicles 11 are to be parked, the parking space conversion module converts the parking spaces so that multiple vehicles 11 can be parked in the parking spaces of the garage rack.

[0061] Meanwhile, when it is necessary to retrieve the vehicle 11, the parking space is converted according to the order submitted by the driver and passenger. The parking space conversion module converts the parking space corresponding to the driver and passenger to the vehicle retrieval position. Under the guidance of the guidance interaction module, the driver and passenger drive the corresponding vehicle 11 away from the parking space.

[0062] Optionally, the parking space conversion module includes an entry station 5 ( Figure 5 (The location marked with a dashed box in the middle) and outbound workstation 4 ( Figure 5 (The location is marked by the dashed box in the middle), at least two parking space conversion units and a location recognition unit, wherein the at least two parking space conversion units are used to convert the positions of at least two parking spaces respectively, and the at least two location recognition units are used to recognize the positions of the inbound workstation 5 and the outbound workstation 4 respectively;

[0063] The parking space conversion unit includes a first conversion chain 1, a second conversion chain, a first sliding seat 2, a second sliding seat 12, a first sliding drive mechanism 3, and a second sliding drive mechanism. The first sliding seat 2 is connected to the first conversion chain 1, and the second sliding seat 12 is connected to the second conversion chain. The first sliding drive mechanism 3 is disposed on the first sliding seat 2, and the second sliding drive mechanism is disposed on the second sliding seat 12.

[0064] The two ends of the parking space are respectively connected to the first sliding seat 2 and the second sliding seat 12;

[0065] Meanwhile, the first conversion chain 1 and the second conversion chain are parallel to each other, so that the first sliding seat 2 and the second sliding seat 12 can be synchronously transferred under the drive of the first sliding drive mechanism 3 and the second sliding drive mechanism, respectively.

[0066] In addition, the first conversion chain 1 and the second conversion chain are configured as a circular track to form a three-dimensional garage for storing multiple vehicles 11;

[0067] It is worth noting that each parking space corresponds to an independent parking space conversion unit and a position recognition unit, enabling the parking space conversion unit to drive the parking space to be converted or moved.

[0068] The location recognition unit is installed on the parking space conversion unit and identifies the positions of the inbound workstation 5 and the outbound workstation 4 so that the parking space can be accurately moved to the positions of the inbound workstation 5 and the outbound workstation 4.

[0069] The location identification unit includes an identification probe and a location comparator. The identification probe is used to identify the positioning marks of the entry station 5 or the exit station 4 to obtain the location data of the entry station 5 and the exit station 4. The location comparator compares the location data collected by the identification probe with the fixed location data stored in the database of the server. If the comparison result is correct, it sends an instruction to the central processing unit so that the central processing unit controls the parking space conversion unit to stop rotating and waits for the driver to drive the vehicle 11 away.

[0070] Optionally, the parking detection unit includes a detection plate 6, a data storage device, at least one pressure detection element, and a tensioning member. The detection plate 6 is disposed in the parking space and detects the vehicle 11 entering the parking space. At least one pressure detection element is evenly distributed on the detection plate 6. The data storage device is used to store the pressure data collected by at least one pressure detection element and the tensioning data detected by the tensioning member.

[0071] When the vehicle 11 enters the parking space, the pressure detection element is squeezed.

[0072] like Figure 7 As shown, optionally, the pulling member includes at least four pulling ropes 7 and at least four tension sensors, with the at least four tension sensors respectively disposed on the at least four pulling ropes to collect the tension data of the vehicle 11 parked in the parking space.

[0073] Among them, at least four pull ropes 7 are symmetrically arranged at the outer edge of the detection pressure plate 6;

[0074] The position evaluation unit acquires the tension data of the vehicle's parking position in the parking space collected by the parking detection unit, and calculates the vehicle's current parking balance index Balance according to the following formula:

[0075] Balance=(F1·k1+F2·k2)-(F3·k1+F4·k2);

[0076] In the formula, F1, F2, F3 and F4 are the real-time tension data of the four pulling ropes, and k1 and k2 are the corresponding sensitivity coefficients, whose values ​​are obtained based on empirical values.

[0077] In this embodiment, specific value examples are provided for k1 and k2, which are the corresponding sensitivity coefficients. Specifically:

[0078] 1) Standard small cars (vehicle weight range: 1000-1500 kg, standard mechanical parking space, suitable for light vehicles, medium sensor accuracy):

[0079] k1: 0.8~1.0;

[0080] k2: 0.9~1.1;

[0081] In this type of parking lot, the vehicles are relatively light, so the sensitivity of the sensors should be moderate, which can detect slight weight changes without being too sensitive due to the light weight. The values ​​of k1 and k2 are close to 1 to ensure that the system can accurately assess the vehicle's balance and make adjustments when it detects a vehicle deviation.

[0082] 2) Large SUVs and trucks (vehicle weight range: 2000-3000 kg, robust garage structure, suitable for heavy vehicles, high sensor accuracy):

[0083] k1: 0.58~0.7;

[0084] k2: 0.6~0.8;

[0085] Because the vehicle is heavy, the system needs to ensure that the sensor is not overloaded; therefore, the sensitivity coefficient should be appropriately reduced. By setting smaller values ​​for k1 and k2, it can be ensured that the tension sensor can work accurately over a larger weight range without exceeding its operating range due to excessive sensitivity.

[0086] In summary, the values ​​of k1 and k2 need to be set according to the specific scenario. Typically, the range of k1 and k2 is between 0.5 and 1.5, which can be adjusted according to the specific vehicle type, sensor accuracy, and garage structure.

[0087] In addition, in scenarios involving lighter vehicles and high-precision sensors, the values ​​of k1 and k2 are higher; while in scenarios involving heavier vehicles and ordinary-precision sensors, the values ​​of k1 and k2 are lower.

[0088] If the value of the parking balance index Balance exceeds the set evaluation threshold Range, the position adjustment unit is triggered to adjust the position of the vehicle 11.

[0089] If the value of the parking balance index Balance is less than or equal to the set evaluation threshold Range, it means that the vehicle is in a balanced position in the parking space, and the parking space timer is triggered to count the parking time.

[0090] In this embodiment, the evaluation threshold Range is set by the system or the administrator. This is a technical means well known to those skilled in the art. Those skilled in the art can consult relevant technical manuals to learn about this technology, so it will not be described in detail in this embodiment.

[0091] Optionally, the position adjustment unit is installed in the parking space and adjusts the parking position of the vehicle 11. The position adjustment unit includes a lifting component and an adjusting component 8. The lifting component is used to adjust the height of the adjusting component 8, and the adjusting component 8 is used to adjust the position of the vehicle 11.

[0092] Specifically, the position adjustment unit is located at the contact position with the wheels of vehicle 11 in the parking space;

[0093] The lifting component includes a lifting rod 13, a lifting drive mechanism, and a lifting detection component. The lifting detection component is used to detect the lifting height of the lifting rod 13. One end of the lifting rod 13 is connected to the adjusting component 8, and the other end of the lifting rod 13 is driven to connect to the lifting drive mechanism to form a lifting part. The lifting part is disposed on the detection pressure plate 6.

[0094] Optionally, the adjustment component 8 includes an adjustment frame, an adjustment belt 9, an adjustment drive mechanism 10, and a distance detection component. The adjustment belt 9 is disposed on the adjustment frame, the adjustment drive mechanism 10 is used to drive the adjustment belt 9, and the distance detection component is used to detect the distance between the vehicle 11 and the edge of the adjustment frame during the adjustment process.

[0095] The parking space is symmetrically equipped with side frames, and the distance detection devices are symmetrically arranged on the side frame walls of the parking space for detecting the distance. When the distance data detected by the symmetrically arranged distance detection devices are the same or similar, it indicates that the vehicle 11 is in the center position or deviates from the allowable range, thus meeting the balance condition.

[0096] It is worth noting that the width of the adjusting belt 9 is greater than that of the wheels of the vehicle 11, so that the adjusting belt 9 can drive the position of the wheels, thereby realizing the adjustment of the position of the vehicle 11 in the garage;

[0097] Through the cooperation of the position adjustment unit and the position evaluation unit, the position adjustment unit can trigger the adjustment of the vehicle 11 according to the evaluation result of the position evaluation unit, so as to improve the safety and reliability of the vehicle 11 stored in the garage.

[0098] In addition, adjusting the position of the vehicle 11 through the position adjustment unit also protects the vehicle 11 so that the vehicle body is not damaged.

[0099] The data acquisition module includes a parking time acquisition unit and a position sensing unit. The parking time acquisition unit acquires the parking time of each parking space, and the position sensing unit acquires the number of rotation steps of the parked vehicle from the parking space to the exit workstation.

[0100] The position sensing unit includes a position recognition probe and at least two position markers. The position recognition probe is used to identify the position of the at least two position markers. The at least two position markers mark at least two parking spaces respectively. The position recognition probe is set on the outbound workstation and identifies the position markers on the parking spaces.

[0101] The parking time acquisition unit calls the parking time timing data from the timer.

[0102] The time acquisition unit is used to obtain the parking time of each parking space and to track the duration of each car parked in the garage in real time by calling the data of the timer of each parking space.

[0103] The time acquisition unit obtains the parking time of each parking space with a parked vehicle according to the following steps:

[0104] S11. The vehicle enters the parking space, and the position of the parked vehicle is detected by the position evaluation unit, and the current parking balance index Balance of the vehicle is calculated. If the value of the parking balance index Balance is less than or equal to the set evaluation threshold Range, it means that the position of the vehicle parked in the parking space has reached balance, and the parking space timer is triggered to count the parking time.

[0105] When the timer is triggered, the parking space number is bound to the vehicle information (such as license plate number or user ID) for subsequent querying.

[0106] S12. The parking timer starts recording the parking duration continuously after the vehicle parks in the parking space. The timer can update the time every second, or every minute or hour according to system settings. The timer data is stored in real time in a database or cache. The parking time for each parking space is linked to the space's number and stored in the corresponding entry in the database to ensure that parking time data is not lost.

[0107] S13. The time acquisition unit sends a query request to the background through the parking space number or vehicle identification information (such as license plate number or reservation ID) to obtain the parking time data of the parking space.

[0108] S14. After receiving the request from the time acquisition unit, the backend will search for the corresponding parking time in the database based on the parking space number or vehicle information. Once the query is successful, the system will retrieve the parking time from the database and return it to the time acquisition unit. The time acquisition unit can then obtain real-time parking duration data.

[0109] The data acquisition module includes a parking time acquisition unit and a position sensing unit. The parking time acquisition unit acquires the parking time of each parking space, and the position sensing unit acquires the number of rotation steps of the parked vehicle from the parking space to the exit workstation.

[0110] The position sensing unit includes a position recognition probe and at least two position markers. The position recognition probe is used to identify the position of the at least two position markers. The at least two position markers mark at least two parking spaces respectively. The position recognition probe is set on the outbound workstation and identifies the position markers on the parking spaces.

[0111] The parking time acquisition unit calls the parking time timing data from the timer.

[0112] The intelligent analysis module calculates the priority index for each parking scheme based on the parking time of each parking space and the number of rotation steps from a parked space to the exit workstation, as collected by the data acquisition module:

[0113]

[0114] In the formula, N represents the number of parking spaces in the garage rack, and priority i For the i-th docking scheme, its value is calculated according to the following formula:

[0115]

[0116] In the formula, T i Let S be the parking time for the i-th parking space. iThe number of rotation steps from parking space i to the outbound workstation is obtained by the position sensing unit, and C is an adjustment coefficient used to calculate according to the following formula:

[0117]

[0118] In the formula, cost max The maximum time taken for the system to complete one rotation (or full rotation) is defined as the time required for the parking space to turn. min The minimum time required for the system to complete one parking space rotation.

[0119] Select the state scheme with the highest priority index from M parking schemes as the execution scheme, so that the parking position state of the garage rack parking space matches the corresponding parking state;

[0120] The parking state refers to an empty parking space facing the entry station, and the number of parking schemes M is equal to the number of empty parking spaces in the garage rack.

[0121] In this embodiment, M+N equals the total number of parking spaces provided by the garage rack. There are M+N parking states in total, that is, a parking space is in the state of entering the garage as a parking state.

[0122] If N parking spaces in the current garage are occupied, then there are M parking options remaining. We only need to select the option with the highest priority index from the M parking options as the execution option to park the vehicle.

[0123] Each time a vehicle enters or exits, the intelligent analysis module is triggered to perform calculations, and the parking space conversion module is triggered to execute the selected scheme.

[0124] Through the cooperation of the intelligent analysis module and the data acquisition module, the parking spaces in the garage rack can be precisely controlled, ensuring that the entire system has the advantages of strong dynamic control capability, high intelligence, reliable priority management, and convenient and comfortable parking and retrieval.

[0125] The guidance and interaction module includes a guidance unit and an interaction unit. The guidance unit is used to guide the driver who drives into the parking space, and the interaction unit is used to interact with the driver to perform parking or retrieval operations on the vehicle 11 driven by the driver.

[0126] Optionally, after the vehicle 11 enters the parking space, the guidance unit is triggered to provide guidance prompts to the driver and passengers, so as to prompt the driver and passengers to retrieve the vehicle or pay the parking fee;

[0127] Optionally, when the driver or passenger needs to retrieve the vehicle, they can interact with the interactive unit via the user terminal, and after verifying the identity of the user terminal, trigger the rotation of the parking space corresponding to their own vehicle 11 so that the parking space is rotated to the outbound workstation 4.

[0128] The guidance unit is installed in the outbound workstation 4 and the inbound workstation 5. The guidance unit includes a voice prompt device and indicator lights. The voice prompt device provides prompts to the driver and passengers based on the pressure data collected by the pressure detection device, and the indicator lights provide light prompts based on the data from the voice prompts.

[0129] In this embodiment, the content prompted by the voice prompt device includes, but is not limited to, the following:

[0130] "Please lock the doors and windows!", "Please turn off the lights!", "Please take your valuables with you!", and "Flammable items are not allowed in the vehicle!" etc.;

[0131] The indicator lights display red, yellow, and green lights;

[0132] The interaction unit includes an interactive device and an authentication terminal. The interactive device is used to collect user terminal and ID card data. The authentication terminal verifies the data based on the user terminal and ID card data and generates a vehicle 11 retrieval command after successful verification. This causes the central processing unit to control the parking space conversion unit to transfer the vehicle 11 associated with the vehicle 11 retrieval command to the outbound workstation 4, so that the driver can enter the vehicle 11 and drive the vehicle 11 away from the parking space.

[0133] It is worth noting that the user terminal specifically refers to a terminal that has undergone real-name authentication and been bound to an ID card;

[0134] In addition, the generated vehicle 11 extraction command is only valid if it is different from the previously generated vehicle 11 extraction command; if they are different, it will be regenerated.

[0135] Through the cooperation of the guidance unit and the interaction unit, the driver and passengers can obtain the best parking comfort, while also taking into account the level of intelligence of human-computer interaction. This makes the whole system have the advantages of convenient vehicle 11 guidance, good garage interaction performance, and simple vehicle 11 storage and retrieval process.

[0136] Example 2: This example should be understood as including all the features of any of the foregoing examples, and further improving upon them, according to... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6, Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, the parking space conversion module also includes an information erasure unit, which is used to remove information about the vehicle 11 that has left the parking space.

[0137] The information erasure unit includes an erasure component and an erasure command generation terminal. The erasure command generation terminal generates an erasure command based on the departure time, parking time and license plate data of the vehicle 11. The erasure component acquires the pressure data collected by the pressure detection component and erasures the vehicle 11 according to the erasure command.

[0138] The erase command generation terminal generates the erase command according to the following formula:

[0139]

[0140] In the formula, code(x) is the value corresponding to the x-th bit of the erase instruction, T0 is the vehicle's parking time, and T j The vehicle's departure time is given, times is the number of stops per day, ID(x) is the x-th value of the identity ID sequence of the driver and passengers associated with the vehicle, and brand(x) is the value corresponding to the x-th value of the vehicle identification information sequence.

[0141] When the driver or passenger needs to use the service, they need to transmit their identity ID data and vehicle identification information to the cloud server. The identity ID data and vehicle identification information can be obtained by the driver or passenger manually inputting them and sending them to the cloud server (for example, by the human-computer interaction module collecting user identity ID data and vehicle identification information and sending them to the cloud server). The cloud server can compare the collected identity ID data with the pre-stored identity ID data and compare the collected vehicle identification information with the pre-stored vehicle identification information to obtain the driver's or passenger's identity ID and vehicle identification information sequence. This allows the cloud server to grasp the driver's or passenger's identity ID data and process the identity ID data to obtain the identity ID sequence and vehicle identification information sequence.

[0142] The processing methods include, but are not limited to, the following: truncating a specified number of bits, hash function processing, encryption algorithm processing, and number processing, etc.; the above processing methods are commonly used in the field, and therefore will not be described in detail in this embodiment.

[0143] Taking an 18-digit ID card number as an example:

[0144] To extract a specified number of digits, extract a specified length of characters or numbers from an 18-digit ID card number as an identification sequence; depending on the specific needs, you can choose to extract the first few or last few digits of the ID card number, or extract a segment of characters or numbers from the middle.

[0145] For hash function processing, hash functions (such as MD5, SHA1, SHA256, etc.) are used to calculate the 18-digit ID card number, generate a fixed-length hash value, and extract a portion of it as the identity recognition sequence.

[0146] For encryption processing, an encryption algorithm (such as AES, RSA, etc.) is used to encrypt the 18-digit ID card number, generating ciphertext, and a portion of it is extracted as the identification sequence. It's important to note that encryption algorithms typically require both public and private keys for encryption and decryption, ensuring that only those with the correct keys can decrypt the original ID card number.

[0147] For number processing, the digits in the 18-digit ID card number are weighted and moduloed to generate a number sequence of a specified number of digits as the identity recognition sequence. Depending on the specific needs, different number processing methods are selected, such as adding the digits in the ID card number and taking the remainder, or combining the digits according to certain rules.

[0148] The erasing component acquires the pressure data collected by the pressure detection component (no pressure data in the parking space or pressure data less than the set pressure threshold). If the pressure data is less than the set pressure threshold, it indicates that the previous vehicle parked in the parking space has left, and the data of the vehicle can be erased.

[0149] The pressure thresholds set above are configured by the system or administrator, which is a well-known technique for those skilled in the art. They can consult relevant technical manuals to learn about this technique, so it will not be described in detail in this embodiment.

[0150] When erasing, it is necessary to simultaneously ensure that there is no vehicle in the parking space and that the erasure command has been generated, then the data associated with the vehicle that was previously parked in the parking space will be erased.

[0151] The information erasure unit erases the information associated with the vehicle, thereby improving the security of the vehicle data, ensuring the security of data of each user or passenger, and preventing the theft of personal information.

[0152] The content disclosed above is only a preferred and feasible embodiment of the present invention, and is not intended to limit the scope of protection of the present invention. Therefore, all equivalent technical changes made based on the content of the present invention specification and drawings are included within the scope of protection of the present invention. Furthermore, the elements therein can be updated as technology develops.
