Description

Technical Field

[0001] This invention relates to the field of Internet of Things (IoT) applications, and in particular to a parking space guidance method, system, electronic device, and storage medium. Background Technology

[0002] With the development of IoT technology, the parking guidance process is gradually becoming more automated and visualized. Digital twin technology is used to digitize and visualize the physical environment of the parking lot, creating a scene mapping and model. When a vehicle enters the parking lot and the user terminal sends a parking request, the real-time data on parking space occupancy is processed and summarized to generate a twin route to the nearest available parking space. This route is then presented to the user terminal as a guidance map, thus guiding the vehicle.

[0003] The shortcomings of existing underground parking lot guidance technologies and the problems to be solved are as follows:

[0004] When parking lots use RFID (Radio Frequency Identification) technology to identify and sense user vehicles, they simply identify the vehicle as "present." When the vehicle has not performed a parking operation or has completed the parking operation, they cannot determine whether the vehicle is in the parking space search state or in the state of preparing to leave the parking space.

[0005] When providing parking guidance routes, drivers are directly directed to the nearest available parking space, lacking further decision-making steps and ignoring the possibility that the provided guidance route may be occupied along the way.

[0006] In existing technologies, the real-time usage status of parking spaces only has two states: "occupied" and "vacant". When a parking space is selected during the guidance phase, other vehicles may still select the same parking space based on the system guidance, which can easily lead to conflicts. Summary of the Invention

[0007] In view of this, the purpose of the present invention is to provide a parking space guidance method, system, electronic device and storage medium. The method fully considers the uncontrollable factor of parking space occupancy during the vehicle guidance process, and constrains parking spaces and vehicles by adding guidance states, thereby obtaining a more reasonable guidance route map, reducing the probability of conflict between vehicles during parking, and improving the user experience.

[0008] In a first aspect, embodiments of the present invention provide a parking space guidance method for parking lots, the method comprising:

[0009] When a vehicle is detected to have arrived at the entrance of the parking lot, the vehicle's license plate information is obtained, and the license plate information and the first parking information are stored in an electronic tag card. The electronic tag card is obtained by the vehicle owner at the entrance of the parking lot. The first parking information is used to indicate that the vehicle is in the parking search state.

[0010] The system uses signal acquisition equipment to acquire real-time parking space status information and vehicle status information for all vehicles in the parking lot. Parking space status information includes: first parking space information, second parking space information, or third parking space information; first parking space information indicates the parking space is in a guiding state; second parking space information indicates the parking space is occupied; and third parking space information indicates the parking space is vacant. Vehicle status information includes: license plate information, parking information, and location information; parking information includes: first parking information, second parking information, or third parking information; second parking information indicates the vehicle is parked; and third parking information indicates the vehicle has left the parking lot.

[0011] Once the signal acquisition device detects the electronic tag card corresponding to the vehicle, it uses the vehicle's location data, the parking space status information in the parking lot, and the vehicle status information of all vehicles in the parking lot to determine the vehicle's guidance route map. The target parking space in the guidance route map is the parking space corresponding to the third parking space information and the parking space corresponding to the third parking information that meets the preset passage conditions.

[0012] After guiding the vehicle to the target parking space using the guidance route map, the first parking information on the electronic tag card is updated to the second parking information, and the parking space status information corresponding to the target parking space is set to the second parking space information.

[0013] In some implementations, after determining the vehicle guidance route map, the method further includes:

[0014] Set the parking space status information corresponding to the target parking space as the first parking space information.

[0015] In some implementations, when a vehicle is detected leaving a target parking space, the method includes:

[0016] Update the second parking information on the electronic tag card to the third parking information; and set the parking space status information corresponding to the target parking space to the third parking space information.

[0017] In some implementations, the method includes detecting when a vehicle arrives at the parking lot exit:

[0018] Clear the first and third parking information stored in the electronic tag card.

[0019] In some implementations, guiding vehicles to a target parking space using a route map includes:

[0020] Once the vehicle guidance route is determined, a preset timer is used to start timing;

[0021] When the timer's duration exceeds the preset time threshold, if the vehicle has not parked in the target parking space, the current target parking space will be recorded as the first target parking space, and the parking space status information corresponding to the first target parking space will be set as the second parking space information.

[0022] The vehicle guidance route map is updated using the current vehicle location data, parking space status information in the parking lot, and vehicle status information of all vehicles in the parking lot; the target parking space in the updated guidance route map is recorded as the second target parking space.

[0023] When the second target parking space is different from the first target parking space, the parking space status information corresponding to the first target parking space is set to the third parking space information, and the updated guidance route map is used to guide the vehicle to the second target parking space.

[0024] In some implementations, determining the vehicle's guidance route map includes:

[0025] Using vehicle location data, parking space status information in the parking lot, and vehicle status information of all vehicles in the parking lot, calculate the parking space advantage value between the vehicle and all parking spaces in the parking lot; the parking space advantage value is calculated according to the following formula:

[0026] S = L*a + N*b;

[0027] Where S is the parking space advantage value; L is the distance from the vehicle to the parking space in the parking lot; a is the first weight value; N is the number of vehicles in motion within a specified distance of the parking space in the parking lot; and b is the second weight value.

[0028] The parking space corresponding to the minimum value among the parking space advantage values ​​is identified as the target parking space, and the target parking space is used to determine the vehicle guidance route map.

[0029] In some implementations, guiding vehicles to a target parking space using a route map includes:

[0030] After determining the vehicle guidance route map, the current target parking space is recorded as the first target parking space, and the presence of other vehicles in the first target parking space is detected in real time.

[0031] When other vehicles are detected in the first target parking space, the vehicle guidance route map is updated using the current vehicle's location data, the parking space status information in the parking lot, and the vehicle status information of all vehicles in the parking lot. The target parking space in the updated guidance route map is recorded as the second target parking space. The second target parking space is different from the first target parking space.

[0032] Use the updated navigation map to guide the vehicle to the second target parking space.

[0033] Secondly, embodiments of the present invention provide a parking space guidance system, the system comprising:

[0034] The vehicle data acquisition module is used to acquire the vehicle's license plate information when a vehicle is detected to have arrived at the entrance of the parking lot, and to store the license plate information and the first parking information in an electronic tag card; wherein, the electronic tag card is obtained by the vehicle owner at the entrance of the parking lot; the first parking information is used to indicate that the vehicle is in the positioning state;

[0035] The parking lot data acquisition module is used to acquire real-time parking space status information and vehicle status information of all vehicles in the parking lot using signal acquisition equipment. The parking space status information includes: first parking space information, second parking space information, or third parking space information; the first parking space information indicates that the parking space is in a guiding state; the second parking space information indicates that the parking space is occupied; and the third parking space information indicates that the parking space is vacant. Vehicle status information includes: license plate information, parking information, and location information; the parking information includes: first parking information, second parking information, or third parking information; the second parking information indicates that the vehicle is parked; and the third parking information indicates that the vehicle has left the parking lot.

[0036] The guidance route determination module is used to determine the vehicle's guidance route map by using the vehicle's positioning data, parking space status information in the parking lot, and vehicle status information of all vehicles in the parking lot after the signal acquisition device detects the electronic tag card corresponding to the vehicle. The target parking space in the guidance route map is the parking space corresponding to the third parking space information and the parking space corresponding to the third parking information that meets the preset passage conditions.

[0037] The parking guidance module is used to guide vehicles to the target parking space using a guidance route map, update the first parking information of the electronic tag card to the second parking information, and set the parking space status information corresponding to the target parking space to the second parking space information.

[0038] Thirdly, embodiments of the present invention also provide an electronic device, including: a processor and a memory; the memory stores a computer program, which, when run by the processor, implements the steps of the parking space guidance method mentioned in the first aspect above.

[0039] Fourthly, embodiments of the present invention also provide a computer-readable storage medium storing a computer program, wherein the computer program, when executed by a processor, implements the steps of the parking space guidance method mentioned in the first aspect above.

[0040] The embodiments of the present invention bring the following beneficial effects:

[0041] This invention provides a parking space guidance method, system, electronic device, and storage medium. In the process of guiding parking spaces, when a vehicle is detected arriving at the parking lot entrance, the vehicle's license plate information is acquired, and the license plate information and initial parking information are stored in an electronic tag. Then, a signal acquisition device is used to acquire real-time parking space status information and the vehicle status information of all vehicles in the parking lot. When the signal acquisition device detects the electronic tag corresponding to a vehicle, it uses the vehicle's location data, the parking space status information, and the vehicle status information of all vehicles in the parking lot to determine a guidance route map for the vehicle. Finally, after guiding the vehicle to the target parking space using the guidance route map, the initial parking information on the electronic tag is updated to the second parking information, and the parking space status information corresponding to the target parking space is set as the second parking space information. The parking space status information includes: first parking space information, second parking space information, or third parking space information; the first parking space information indicates that the parking space is in a guidance state; the second parking space information indicates that the parking space is occupied; and the third parking space information indicates that the parking space is vacant. Vehicle status information includes: license plate information, parking information, and location information; parking information includes first parking information, second parking information, or third parking information; the second parking information indicates that the vehicle is parked; and the third parking information indicates that the vehicle is exiting the parking space. The target parking space in the guidance route map is one that meets the preset passage conditions from the parking spaces corresponding to the third parking space information and the parking spaces corresponding to the third parking information. This method fully considers the uncontrollable factor of parking space occupancy during the vehicle guidance process and constrains parking spaces and vehicles by adding guidance states, thereby obtaining a more reasonable guidance route map, reducing the probability of conflicts between vehicles during parking, and improving the user experience.

[0058] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. 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.

[0059] With the development of IoT technology, the parking guidance process is gradually becoming more automated and visualized. Digital twin technology is used to digitize and visualize the physical environment of the parking lot, creating a scene mapping and model. When a vehicle enters the parking lot and the user terminal sends a parking request, the real-time data on parking space occupancy is processed and summarized to generate a twin route to the nearest available parking space. This route is then presented to the user terminal as a guidance map, thus guiding the vehicle.

[0060] The shortcomings of existing underground parking lot guidance technologies and the problems to be solved are as follows:

[0061] When parking lots use RFID (Radio Frequency Identification) technology to identify and sense user vehicles, they simply identify the vehicle as "present." When the vehicle has not performed a parking operation or has completed the parking operation, they cannot determine whether the vehicle is in the parking space search state or in the state of preparing to leave the parking space.

[0062] When providing parking guidance routes, drivers are directly directed to the nearest available parking space, lacking further decision-making steps and ignoring the possibility that the provided guidance route may be occupied along the way.

[0063] In existing technologies, the real-time usage status of parking spaces only has two states: "occupied" and "vacant". When a parking space is selected during the guidance phase, other vehicles may still select the same parking space based on the system guidance, which can easily lead to conflicts.

[0064] To address the aforementioned issues, this invention provides a parking space guidance method, system, electronic device, and storage medium. This method fully considers the uncontrollable factor of parking spaces being occupied during the vehicle guidance process and constrains parking spaces and vehicles by adding guidance states, thereby obtaining a more reasonable guidance route map, reducing the probability of conflicts between vehicles during parking, and improving the user experience.

[0065] To facilitate understanding of this embodiment, a parking space guidance method disclosed in this invention will first be described in detail, such as... Figure 1 As shown, the method includes:

[0066] Step S101: When a vehicle is detected to have arrived at the entrance of the parking lot, the vehicle's license plate information is obtained, and the license plate information and the first parking information are stored in the electronic tag card.

[0067] When a vehicle arrives at the parking lot entrance, its license plate information is collected by relevant data acquisition equipment at the entrance. For example, high-definition video capture equipment can be installed at the entrance to obtain the license plate information through image recognition and analysis. The electronic tag is obtained by the vehicle owner at the parking lot entrance. Once the license plate information is acquired and stored on the electronic tag, it is automatically provided to the owner through relevant equipment at the entrance. At this point, the electronic tag contains initial parking information, indicating that the vehicle is in a positioning state.

[0068] Step S102: Use signal acquisition equipment to obtain real-time parking space status information in the parking lot and vehicle status information of all vehicles in the parking lot.

[0069] The signal acquisition equipment is installed inside the parking lot to obtain real-time parking space status information and the status information of other vehicles. The parking space status information includes: first parking space information, second parking space information, or third parking space information. Specifically, first parking space information indicates that the parking space is in a guided state; second parking space information indicates that the parking space is occupied; and third parking space information indicates that the parking space is vacant.

[0070] Vehicle status information includes: license plate information, parking information, and location information; specifically, parking information is first parking information, second parking information, or third parking information; among them, first parking information indicates that the vehicle is in the search state; second parking information indicates that the vehicle is in the parking state; and third parking information indicates that the vehicle is in the exit state.

[0071] As can be seen, parking space status information mainly describes the current state of the parking space, including three categories: guidance status, occupied status, and vacant status. Vehicle status information mainly represents the current state of the vehicle, including: searching for a parking space, parking status, and exiting the parking space. It is evident that parking space status information and vehicle status information are mutually corresponding, representing the three states of searching, parking, and vacant, respectively.

[0072] Step S103: After the signal acquisition device detects the electronic tag card corresponding to the vehicle, it uses the vehicle's positioning data, the parking space status information in the parking lot, and the vehicle status information of all vehicles in the parking lot to determine the vehicle's guidance route map.

[0073] In step S102, parking space status information and vehicle status information are obtained, but this does not yet include information about vehicles entering the parking lot. When the signal acquisition device detects the electronic tag card corresponding to a vehicle, it can be understood as triggering the parking guidance process. At this time, the vehicle's location data, the parking space status information, and the vehicle status information of all vehicles in the parking lot are used to determine the vehicle's guidance route map.

[0074] It's worth noting that the target parking spaces in the guidance route map are those that meet the preset access conditions, from the parking spaces corresponding to the third parking space information and the parking spaces corresponding to the third parking information. The guidance route, while satisfying the above target parking spaces, avoids vehicles in motion as much as possible, and the distance of the guidance route is as short as possible. The selection process for target parking spaces needs to consider avoiding parking spaces in the guidance state and those in the occupied state, and select from parking spaces that are in the vacant state. In actual scenarios, the parking status of other vehicles must also be considered; when a vehicle has already left the parking space, that space can be directly selected as a candidate target parking space.

[0075] Step S104: After guiding the vehicle to the target parking space using the guidance route map, update the first parking information of the electronic tag card to the second parking information, and set the parking space status information corresponding to the target parking space to the second parking space information.

[0076] Once the vehicle completes the parking process by parking in the target parking space under the guidance of the route map, the first parking information on the electronic tag is updated to the second parking information, meaning the parking information on the electronic tag changes from a search status to a parked status. Simultaneously, the parking space status information corresponding to the target parking space is updated from the third parking space information to the second parking space information, meaning the parking space status changes from vacant to occupied.

[0077] In the parking guidance method described above, once the vehicle guidance route map is determined, it is sent to the car owner. The car owner then displays and executes the guidance process via their terminal, such as a mobile phone or in-vehicle infotainment system. However, during the guidance process, the target parking space remains the third available parking space; that is, the target parking space is still vacant. Before guiding the vehicle, the parking space status information corresponding to the target parking space needs to be set to occupied to prevent the target parking space from being occupied by other vehicles during the guidance process.

[0078] In some implementations, such as Figure 2 As shown, the method also includes:

[0079] Step S201: When a vehicle is detected to have arrived at the entrance of the parking lot, the vehicle's license plate information is obtained, and the license plate information and the first parking information are stored in the electronic tag card.

[0080] Step S202: Use signal acquisition equipment to obtain real-time parking space status information in the parking lot and vehicle status information of all vehicles in the parking lot.

[0081] Step S203: After the signal acquisition device detects the electronic tag card corresponding to the vehicle, it uses the vehicle's positioning data, the parking space status information in the parking lot, and the vehicle status information of all vehicles in the parking lot to determine the vehicle's guidance route map.

[0082] Step S204: Set the parking space status information corresponding to the target parking space as the first parking space information.

[0083] After the guiding image is acquired, the parking space status information of the target parking space is changed from the third parking space information to the first parking space information, that is, from the vacant state to the occupied state.

[0084] Step S205: After guiding the vehicle to the target parking space using the guidance route map, update the first parking information of the electronic tag card to the second parking information, and set the parking space status information corresponding to the target parking space to the second parking space information.

[0085] After the vehicle completes parking in the above embodiments, it is also necessary to consider the situation when the vehicle leaves the target parking space. In some embodiments, such as Figure 3 As shown, the parking space guidance method for this parking lot includes:

[0086] Step S301: When a vehicle is detected to have arrived at the entrance of the parking lot, the vehicle's license plate information is obtained, and the license plate information and the first parking information are stored in the electronic tag card.

[0087] Step S302: Use signal acquisition equipment to obtain real-time parking space status information in the parking lot and vehicle status information of all vehicles in the parking lot.

[0088] Step S303: After the signal acquisition device detects the electronic tag card corresponding to the vehicle, it uses the vehicle's positioning data, the parking space status information in the parking lot, and the vehicle status information of all vehicles in the parking lot to determine the vehicle's guidance route map.

[0089] Step S304: After guiding the vehicle to the target parking space using the guidance route map, update the first parking information of the electronic tag card to the second parking information, and set the parking space status information corresponding to the target parking space to the second parking space information.

[0090] Step S305: When a vehicle is detected leaving the target parking space, the second parking information of the electronic tag card is updated to the third parking information; and the parking space status information corresponding to the target parking space is set to the third parking space information.

[0091] The detection process of a vehicle leaving a target parking space can be achieved through signal acquisition equipment. By comparing the vehicle's positioning data with the target parking space's positioning data, it can be determined whether the vehicle has left the target parking space. When a vehicle is detected to have left the target parking space, the second parking information on the electronic tag is updated to the third parking information, that is, the vehicle changes from a parked state to an exited state. At the same time, the parking space status information corresponding to the target parking space is set to the third parking space information, that is, the parking space changes from an occupied state to an vacant state.

[0092] When a vehicle leaves the target garage, it indicates that the vehicle is about to leave the parking lot. Therefore, in some implementations, when the vehicle is detected to have arrived at the exit of the parking lot, the method further includes: clearing the first parking information and the third parking information stored in the electronic tag card.

[0093] The third parking information indicates that the vehicle is in the exiting state. Therefore, when the vehicle reaches the parking lot exit, the third parking information in the electronic tag is cleared. In actual scenarios, there may be situations where a vehicle enters the parking lot but does not stop and exits directly. In this case, the parking information in the electronic tag is the first parking information. Therefore, when the vehicle is detected to have reached the parking lot exit, the first parking information in the electronic tag also needs to be cleared.

[0094] In real-world scenarios, not only do vehicles sometimes enter a parking lot but leave without stopping, but they may also fail to park in the target space due to other factors. Therefore, some implementations utilize guided route maps to direct vehicles to the target parking space, such as... Figure 4 As shown, it includes:

[0095] Step S401: After determining the vehicle guidance route map, start timing using a preset timer.

[0096] Once the vehicle guidance route map is determined, a preset timer starts timing. At this time, the vehicle is also in the guidance state, and the driver drives the vehicle to the target parking space according to the guidance route map.

[0097] Step S402: When the timer's duration exceeds the preset time threshold, if the vehicle has not parked in the target parking space, the current target parking space is recorded as the first target parking space, and the parking space status information corresponding to the first target parking space is set as the second parking space information.

[0098] During the process of a vehicle moving towards its target parking space, it may be affected by other factors. Passive factors mainly include: the vehicle being involved in an accident, or other vehicles breaking down and blocking the road; active factors mainly include: the driver voluntarily giving up parking in the target space, or the driver voluntarily leaving the parking lot instead of parking. Therefore, the process of whether a vehicle has parked in the target parking space can be judged based on a preset time threshold. Specifically, if the vehicle has not parked in the target parking space after the preset time exceeds the threshold, it indicates that the target parking space is no longer needed. At this time, the parking space status of the current target parking space is changed from the first parking space information to the second guidance information, that is, the parking space is changed from the guidance status to the occupied status.

[0099] Step S403: Update the vehicle guidance route map using the current vehicle's location data, parking space status information in the parking lot, and vehicle status information of all vehicles in the parking lot; wherein, the target parking space in the updated guidance route map is recorded as the second target parking space.

[0100] Once the original target parking space is no longer considered, the vehicle guidance route map is updated using the current vehicle location data, parking space status information in the parking lot, and vehicle status information of all vehicles in the parking lot. The target parking space in the new guidance map is then used to guide vehicles to park.

[0101] Step S404: When the second target parking space is different from the first target parking space, set the parking space status information corresponding to the first target parking space to the third parking space information, and use the updated guidance route map to guide the vehicle to the second target parking space.

[0102] If the second target parking space is different from the first target parking space, the first target parking space will be reset to the third parking space information, i.e., vacant. If the second target parking space is the same as the first target parking space, the parking space status of the first target parking space will be changed from the second parking space information to the first guidance information, i.e., the parking space will be changed from occupied to guided.

[0103] In some implementations, a vehicle guidance route map is determined, such as Figure 5 As shown, it includes:

[0104] Step S501: Using the vehicle's location data, the parking space status information in the parking lot, and the vehicle status information of all vehicles in the parking lot, calculate the parking space advantage value between the vehicle and all parking spaces in the parking lot.

[0105] The parking space advantage value is calculated using the following formula:

[0106] S = L*a + N*b;

[0107] Where S is the parking space advantage value; L is the distance from the vehicle to the parking space in the parking lot; a is the first weight value; N is the number of vehicles in motion within a specified distance of a parking space in the parking lot; and b is the second weight value. It is worth mentioning that in actual scenarios, N can be further limited to the number of vehicles in motion that are searching for parking spaces; while vehicles in the exiting state will not affect parking space guidance.

[0108] Step S502: Determine the parking space corresponding to the minimum value among the parking space advantage values ​​as the target parking space, and use the target parking space to determine the vehicle guidance route map.

[0109] The calculation process for the target parking space no longer simply calculates the nearest distance between the vehicle's coordinates and the parking space's location. Instead, it fully considers the number of vehicles in motion around the vacant parking space and calculates the parking space advantage value by setting corresponding weight values. The calculation process is performed on all vacant parking spaces, and the parking space with the minimum parking space advantage value is selected as the target parking space.

[0110] After the target parking space is selected, a guidance route map is generated based on the vehicle's current location coordinates, the target parking space coordinates, and the positional relationships of other vehicles and other parking spaces.

[0111] When using a route map to guide vehicles to a target parking space, there may be situations where the target parking space is forcibly occupied. Therefore, in some implementations, a guidance route map is used to guide vehicles to the target parking space, such as... Figure 6 As shown, it includes:

[0112] Step S601: After determining the vehicle guidance route map, the current target parking space is recorded as the first target parking space, and the presence of other vehicles in the first target parking space is detected in real time.

[0113] The signal acquisition device is used to collect real-time signals of the current target parking space to determine whether the current target parking space is forcibly occupied by other vehicles.

[0114] Step S602: When other vehicles are detected in the first target parking space, the vehicle guidance route map is updated using the current vehicle's location data, the parking space status information in the parking lot, and the vehicle status information of all vehicles in the parking lot. The target parking space in the updated guidance route map is recorded as the second target parking space. The second target parking space is different from the first target parking space.

[0115] When it is detected that the current target parking space is occupied by another vehicle, the vehicle guidance route map is updated using the current vehicle's location data, the parking space status information in the parking lot, and the vehicle status information of all vehicles in the parking lot. The target parking space in the new guidance route map is then used as the new target parking space, i.e., the second target parking space. Since the first target parking space has already been occupied, the second target parking space will definitely be different from the first target parking space.

[0116] Step S603: Guide the vehicle to the second target parking space using the updated guidance route map.

[0117] The new guidance route map directs vehicles to the second target parking space, thus avoiding conflicts with vehicles in the first target parking space. Although the vehicles in the first target parking space are forcibly occupied, this method can also handle this special situation in real time, thereby reducing conflict scenarios.

[0118] like Figure 7 The image shows a parking guidance method, with triangles representing vehicles and rectangles representing parking spaces. The top triangle represents the vehicle needing guidance, while the other triangles represent vehicles in motion. This method identifies three parking space states: occupied, guiding, and vacant. Spaces being guided are occupied by other moving vehicles; therefore, only vacant spaces can be used to determine the guidance route for the vehicles needing guidance. Figure 7 The circle in the diagram represents the area within a specified radius around the parking space. By obtaining the number of vehicles in motion within this area, and combining the first weight value and the second weight value, the parking space advantage value corresponding to the parking space is calculated. The parking space with the minimum parking space advantage value is selected as the target parking space, and a guidance route map is generated to guide vehicles to the parking space.

[0119] In real-world scenarios, parking space guidance methods can be implemented based on relevant hardware modules, including: user terminal module, data acquisition module, data processing module, and parking space guidance module.

[0120] The user terminal module enables users to connect to the relevant cloud server via an app, and receive parking space information and parking guidance information after issuing a parking request. The cloud server serves as the access platform for this method, and in practical scenarios, it can be implemented through a digital twin parking management system; while the user terminal app is a subsystem of the digital twin parking management system.

[0121] The data acquisition module is mainly used to collect various types of data. For example, high-definition video acquisition equipment is installed at the garage entrance to analyze vehicle license plate information through image recognition and connect to RFID reader / writer devices to store the information in blank RFID electronic tags in real time. RFID signal acquisition equipment is deployed inside the parking lot to collect parking space status information and information from the RFID electronic tags obtained by vehicle owners at the parking lot entrance.

[0122] Specifically, the parking space information includes the parking space number; the location coordinates of the parking space in the twin system; and the parking space status ("occupied", "vacant", and "guiding"). When the parking space status is "guiding", the cloud server automatically binds the parking space information to the user's vehicle's RFID electronic tag information. Other users using incorrect RFID electronic tags will not be able to occupy the parking space. This ensures that when the parking space is occupied or is being occupied by the parking space guidance process, the parking space is in an unselectable state in the system and in the actual physical space, avoiding the occurrence of the above-mentioned scenario two.

[0123] Vehicle information includes: license plate information, vehicle status ("entering the warehouse", "parking status", and "preparing to leave the warehouse"). This ensures that the vehicle data in the data processing module can be differentiated based on the vehicle status.

[0124] Parking spaces are equipped with long-range RFID readers, which combine scanning and RFID functions. The vehicle status is set according to the following principle: upon initial entry into the parking space, the RFID reader defaults to storing the vehicle status as "entering the parking space"; upon entering the parking space, the RFID electronic tag is manually used to trigger the long-range RFID reader at the parking space, changing the vehicle status to "parked" and the parking space status to "occupied"; upon leaving the parking space, the RFID electronic tag is manually used again to change the parking space status and vehicle status to "idle" and "preparing to leave," respectively.

[0125] The aforementioned vehicle positioning and parking space positioning are both based on the existing digital twin system model library. During calculation and management, the coordinates of the vehicle twin model in the twin system are used for mapping.

[0126] The data processing module calculates the optimal guidance route based on the collected real-time data, providing decision support for the guidance route. It no longer solely relies on the distance between parking space coordinates and vehicle location information within the twin system as the decision support for parking guidance. Instead, it uses two indicators: distance and the number of vehicles entering at equal intervals near available parking spaces, assigning weights to calculate the advantageous parameters for each parking space.

[0127] Parking space advantage parameter = distance from vehicle to parking space * weight A + number of vehicles in a free-roaming (entering) state within a specified distance range near the parking space * weight B;

[0128] Theoretically, the smaller the parking space advantage parameter, the better the resulting guidance route. Specifically, the distance from the vehicle to the parking space is theoretically the distance from the entrance to the parking space, and this value can be fixed in the cloud server's storage device for different parking spaces. The specified distance range is the distance between the current vehicle and the parking space. The vehicle twin information mapped in real-time in the cloud server, including vehicle information in the "entering parking space search" state, is handed over to the data processing module. A distance calculation method based on twin routes is used to calculate the distance between the vehicle and the parking space, thereby calculating the number of vehicles entering within the specified distance range. The weights can be configured in actual application, and in principle, all weights can be set to 50%.

[0129] The parking guidance module is primarily used to guide vehicles to parking spaces. Based on the parking advantage parameters of currently available parking spaces provided by the data processing module, it selects the parking space with the smallest advantage parameter, calculates the optimal guidance route, and then provides the user with a route map of the optimal parking guidance scheme through route mapping in the digital twin system. This route map is transmitted to the user's terminal in real time, providing route guidance. For details of the above implementation process, please refer to [link / reference]. Figure 8 As shown, it will not be elaborated further here.

[0130] As can be seen from the parking space guidance method in the above embodiments, this method fully considers the uncontrollable factor of parking spaces being occupied during the vehicle guidance process, and constrains parking spaces and vehicles by adding guidance states, thereby obtaining a more reasonable guidance route map, reducing the probability of conflicts between vehicles during the parking process, and improving the user experience.

[0131] Corresponding to the above-described parking space guidance method embodiments, this invention provides a parking space guidance system, such as... Figure 9 As shown. The system includes:
