[0001] This disclosure relates to the field of shared transportation technology, and in particular to a method and apparatus for detecting parking status. Background Technology

[0002] In recent years, the booming development of shared bicycles and e-bikes has facilitated citizens' travel, but disorderly parking has also obstructed traffic and negatively impacted the city's image. Disorderly parking is the number one problem that needs to be solved in the development of shared two-wheelers. Designated parking technology requires users to complete the return process only in designated areas and locations, effectively strengthening the standardized management of shared two-wheelers and addressing the problem of chaotic parking.

[0003] Currently, Bluetooth beacon technology can be used to detect shared two-wheeled vehicles, enabling them to park at designated locations. However, the detection accuracy of Bluetooth beacons is insufficient for detecting parked vehicles. Summary of the Invention

[0006] The method, applied to road stud devices installed on the ground in a parking area, includes:

[0007] Read the NFC tag information and determine whether the device that sent the NFC tag information is a vehicle;

[0008] If so, then the parking status information of the vehicle is determined to be fixed-point parking;

[0009] The parking status information is sent to the vehicle's associated device so that the associated device can trigger the vehicle return process based on the parking status information.

[0013] The sending module is used to send the parking status information to the associated device of the vehicle, so that the associated device can trigger the vehicle return process based on the parking status information.

[0014] Thirdly, this disclosure provides a road stud device, which is installed on the ground in a parking area. The road stud device includes a near-field communication (NFC) module and a Bluetooth communication module; the NFC module is connected to the Bluetooth communication module.

[0015] The NFC module is used to read NFC tag information; based on the NFC tag information, it determines whether the device that sent the NFC tag information is a vehicle; if so, it determines that the vehicle's parking status information is fixed-point parking.

[0016] The Bluetooth communication module is used to send the parking status information to the vehicle's associated device, so that the associated device can trigger the vehicle return process based on the parking status information.

[0017] Fourthly, this disclosure provides a road stud device, including a memory, a processor, a near-field communication (NFC) module, and a Bluetooth communication module; the memory stores a computer program, and the processor executes the computer program to implement the steps of the above-described parking state detection method;

[0018] The NFC module is used to read NFC tag information;

[0019] The Bluetooth communication module is used to send the parking status information to the vehicle's associated devices.

[0020] Fifthly, embodiments of this disclosure provide a road stud device, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the method described in the first aspect.

[0022] In a seventh aspect, embodiments of this disclosure provide a computer program product, including a computer program that, when executed by a processor, implements the method described in the first aspect above.

[0023] The parking status detection method, apparatus, road stud device, and storage medium provided in this disclosure are applied to road stud devices installed on the ground in parking areas. These road stud devices can read NFC tag information and determine whether the device sending the NFC tag information is a vehicle. If the NFC tag information is determined to be sent by a vehicle, the parking status information of the vehicle is determined to be fixed-point parking. The parking status information is further sent to the vehicle's associated device, which triggers a vehicle return process based on the parking status information. Since the road stud device is installed on the ground in the parking area, the parking status of vehicles is detected by the road stud device installed on the ground, eliminating the need to install detection devices on the vehicles, avoiding the modification of a large number of vehicles, and reducing the cost of parking status detection. Furthermore, since NFC communication is short-range communication, the road stud device reads the NFC tag information on the vehicle via NFC communication. The NFC tag information can only be read when the road stud device is sufficiently close to the NFC tag on the vehicle. Therefore, the road stud device in this disclosure has high accuracy in detecting vehicle parking, improving the accuracy of parking detection, and thus better constraining fixed-point parking of vehicles.

[0040] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the embodiments of this disclosure will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the embodiments of this disclosure and are not intended to limit the embodiments of this disclosure.

[0041] First, before introducing the technical solutions of the embodiments of this disclosure, the technical background or evolution of the embodiments of this disclosure will be introduced. Typically, in the ride-hailing field, the current technical background is: vehicle location is determined via Bluetooth modules, allowing users to return the vehicle after it is parked in a designated parking area. Based on this background, through long-term scenario research and the collection, demonstration, and verification of experimental data, the applicant found that the positioning accuracy of Bluetooth modules is low. This can easily lead to situations where the vehicle is not parked in a designated parking area, yet the detection result still indicates that the vehicle is in a designated parking space, resulting in poor vehicle parking management. How to improve the detection accuracy of vehicle parking and enhance the accuracy of vehicle parking status detection has become an urgent problem to be solved. Furthermore, it should be noted that the applicant has devoted considerable creative effort to addressing the technical problems in the embodiments of this disclosure and to developing the technical solutions described in the following embodiments.

[0042] The technical solutions involved in the embodiments of this disclosure will be described below in conjunction with the scenarios in which they are applied.

[0043] The parking status detection method provided in this disclosure can be applied to, for example... Figure 1 The system architecture shown includes a vehicle 101, a client 102, a server 103, and a road stud device 100. The vehicle 101 can be a non-motorized or motorized vehicle such as a bicycle, electric bicycle, scooter, or motorcycle; the client 102 can be an electronic device such as a mobile phone, tablet, or iPad, or an app installed on the electronic device; the server 103 can be an independent server or a server cluster composed of multiple servers. The vehicle 101 is equipped with a communication component, which can communicate wirelessly with the client 102 or the server 103. For example, the client 102 can send an unlock command to the vehicle based on the user's unlocking operation. Furthermore, the client 102 and the server 103 can communicate wirelessly or via wired means. This embodiment does not limit the communication method between the vehicle 101, the client 102, and the server 103. The road stud device 100 can be used to detect the parking status of the vehicle 200; it can detect the parking status of one vehicle 200 or multiple vehicles 200, and this is not limited here. The aforementioned road stud device 100 can be installed on the ground of the parking area, or it can be attached to the surface of the parking area, or other materials can be covered on the surface of the road stud device 100, which is not limited here.

[0044] In one embodiment, such as Figure 2 As shown, a method for detecting parking status is provided, which can be applied to... Figure 1 The following explanation uses the rail spike equipment as an example, including:

[0045] S101. Read the NFC tag information and determine whether the device that sent the NFC tag information is a vehicle.

[0046] The NFC tag information mentioned above can be information stored in the NFC tag. The NFC tag can be placed on the vehicle. To enable the road beacon device to read the tag information on the vehicle, the NFC tag can be placed close to the ground, such as on the vehicle's foot pedals, the bottom of the vehicle frame, or the footrest. The placement of the NFC tag is not limited here. Optionally, when the vehicle is parked upright, the distance between the NFC tag and the ground can be less than a preset threshold, such as 20 centimeters. The NFC tag can be an active or passive tag; this is not limited here.

[0047] The aforementioned road stud device can be used to detect the parking status of vehicles; it can detect the parking status of one vehicle or multiple vehicles, without limitation. The road stud device can be installed on the ground in the parking area; it can be attached to the surface of the parking area or covered with other materials. One or more road stud devices can be installed in the parking area, without limitation.

[0048] The aforementioned road stud device may include an NFC module, which may include an NFC reader and at least one NFC coil. The NFC coil can be used to transmit data sent by the NFC reader or to receive data sent by the NFC tag. The NFC coil can be a single-ended antenna or a differential antenna.

[0049] The NFC tag information described above can store the vehicle's identification code or the tag information corresponding to that code, and these NFC tag information can be one-to-one with the vehicle's identification code. The tag information can consist of numbers or a combination of numbers and letters, and the combination of numbers and letters can be arranged according to a preset rule. The specific format of the tag information is not limited here.

[0050] The road stud device can send an NFC read command, enabling NFC tags within the NFC receiving range of the road stud device to receive the NFC read command and return the NFC tag information stored in the NFC tag to the road stud device based on the NFC read command.

[0051] The aforementioned road stud device can automatically send reading commands according to a preset cycle to obtain information from the NFC tag near the road stud device; it can also start sending reading commands to obtain information from the NFC tag near the road stud device after a preset trigger condition is met; the above reading method is not limited here.

[0052] Because the NFC tags near the road beacon device can be NFC tags not only on vehicles, but also on other objects, such as NFC access cards, the road beacon device needs to determine whether the device that sent the tag information is a vehicle after reading the tag information.

[0053] The road beacon device can determine whether the sender of NFC tag information is a vehicle based on preset encoding rules for vehicle tag information. In one implementation, the road beacon device can determine whether the number of digits in the NFC tag information matches the number of digits in the vehicle's NFC tag information; alternatively, the road beacon device can also read preset characters in the NFC tag information to determine whether they match preset characters in the vehicle's NFC tag information. If the above information matches, it can be determined that the NFC tag information was sent by a vehicle. For example, the NFC tag information on a vehicle may be in the format "QF000000". When the number of digits in the NFC tag information read by the road beacon device is less than or more than the number of digits corresponding to the above format, it can be determined that the NFC tag information was not sent by a vehicle; the road beacon device can also read the first two characters in the NFC tag information. If the read characters are not "QF", then it can be determined that the NFC tag information was not sent by a vehicle.

[0054] S102. If yes, then determine the vehicle's parking status information as fixed-point parking.

[0055] Because the NFC module has a limited reading range, it can only read NFC tag information when a vehicle is close to the road beacon device. Therefore, when the road beacon device reads the NFC tag information and determines that the NFC tag information was sent by the vehicle, it can determine that the vehicle's parking status is designated parking. If the NFC tag information received by the road beacon device is not sent by the vehicle, no judgment is made on the parking status. If the road beacon device receives a parking request from a vehicle but does not read the NFC tag information on the vehicle, it can determine that the vehicle's parking status is illegal parking. The parking request can be triggered by the user through a user-side application, by the road beacon device detecting a vehicle intending to park, or by the vehicle's central control device sending the request after the user initiates a vehicle return operation. The method of determining the parking request is not limited here.

[0056] The vehicle's parking status information can be identified by characters or numbers, without limitation. For example, a parking status of "1" indicates that the vehicle is parked at a designated location; a parking status of "0" indicates that the vehicle is illegally parked.

[0057] S103. Send the parking status information to the vehicle's associated device so that the associated device can trigger the vehicle return process based on the parking status information.

[0058] The associated devices for the aforementioned vehicles can be the vehicle's central control system or the user terminal used by the user who unlocks the vehicle. The road beacon device can trigger the vehicle return process based on parking status information through the associated device. The associated device can trigger the return process when the parking status information indicates fixed-point parking; it can also determine whether to trigger the return process based on parking status information and the vehicle's movement status, for example, the associated device can trigger the return process when the vehicle's parking status information indicates fixed-point parking and the vehicle is not moving.

[0059] In the above-described vehicle return process, the associated device can send a locking command to the vehicle lock component in the central control device, enabling the vehicle lock component to lock the vehicle in response to the user's return operation, or to return the vehicle automatically. Alternatively, in the above-described vehicle return process, the associated device can also send a command to the user's terminal via the cloud platform, and then control the vehicle lock component to lock the vehicle after responding to the user's return trigger operation on the user's terminal; the specific method and process of the above-described vehicle return process are not limited here.

[0060] The parking status detection method provided in this embodiment allows the road beacon device to read NFC tag information and determine whether the device sending the NFC tag information is a vehicle. If the NFC tag information is determined to be sent by a vehicle, the parking status information of the vehicle is determined to be fixed-point parking. The parking status information is then sent to the vehicle's associated device, which triggers a vehicle return process based on the parking status information. Since the road beacon device is installed on the ground in the parking area, the parking status of the vehicle is detected by the road beacon device installed on the ground, eliminating the need to install detection devices on the vehicle itself. This avoids the need to modify a large number of vehicles and reduces the cost of parking status detection. Furthermore, since NFC communication is short-range communication, the road beacon device reads the NFC tag information on the vehicle via NFC communication. The NFC tag information can only be read when the road beacon device is sufficiently close to the NFC tag on the vehicle. Therefore, the road beacon device in this embodiment has high accuracy in detecting vehicle parking, improving the accuracy of parking detection and thus better constraining fixed-point parking.

[0061] The following embodiments provide a detailed description of different implementation methods for the vehicle return process.

[0062] In one embodiment, the road beacon device can send the aforementioned parking status information to the vehicle, triggering a return process via the vehicle's central control system. The road beacon device can connect to the vehicle's central control system via Bluetooth communication module to send the parking status information. After receiving the parking status information, the vehicle can determine whether it is in a designated parking position. If the vehicle is in a designated parking position, the central control system can respond to the user's return operation; that is, after the user performs the locking operation, the vehicle's lock components can lock the vehicle.

[0063] The above-mentioned parking status detection method allows users to return the car without performing any operations on their user terminals, simplifying the car return process.

[0064] In one embodiment, the information sent by the road beacon device to the central control device also includes the vehicle's NFC tag information. This NFC tag information can be used to instruct the central control device to match and verify the NFC tag information with the vehicle's identifier, and to determine whether to respond to the user's vehicle return operation based on the verification result. The vehicle's central control device can store the vehicle's identifier. Since there is a one-to-one correspondence between the vehicle's identifier and the NFC tag information on the vehicle, the central control device can determine whether the NFC tag information read by the road beacon device is the vehicle's tag information based on a preset correspondence between NFC tag information and the vehicle's identifier. If so, the verification result is considered successful; if the NFC tag information does not match the vehicle's identifier, the verification result is considered unsuccessful. If the verification is successful, the central control device can respond to the user's vehicle return operation. If the verification fails, the central control device may assume that the NFC tag information read by the road beacon device was not sent by the vehicle and cannot determine that the vehicle is in a fixed-point parking state. In this case, the central control device will not respond to the user's return operation. That is to say, after the user performs the locking operation, the vehicle's lock component does not complete the locking. The vehicle may send a return failure prompt message to the user. The above prompt message can be a voice prompt message on the vehicle or a prompt message on the user's client. There is no limitation here.

[0065] The above-described parking status detection method eliminates the need for users to perform any operations on their terminals to return the vehicle, simplifying the return process. Furthermore, when multiple vehicles simultaneously receive parking status information from the beacon device, the system may mistakenly identify the parking status information of other vehicles as its own. The central control unit can avoid this situation by matching and verifying the tag information, thus improving the accuracy of parking status detection.

[0066] In one embodiment, the central control device can send parking status information and NFC tag information to the cloud platform. After receiving the information, the cloud platform will match and verify the NFC tag information with the vehicle's identifier. If the verification is successful, the cloud platform will send a return permission command to the vehicle's central control device, enabling the vehicle to respond to the user's return operation.

[0067] The aforementioned parking status detection method matches the vehicle's NFC tag information with the vehicle's identifier through a cloud platform, eliminating the need for the central control unit to store the correspondence between NFC tag information and vehicle identifiers, thus simplifying vehicle maintenance. Furthermore, if the NFC tag on the vehicle is damaged or lost, individual vehicle maintenance is not required; the correspondence can be updated in the cloud platform, further reducing vehicle maintenance costs.

[0068] In one embodiment, the road beacon device can also send the parking status information to the user terminal. The road beacon device can send the parking status information to the user terminal via a Bluetooth communication module. After receiving the parking status information, the user terminal can display a "allow return" control on the application interface. After the user triggers the control, the user terminal can send a "allow return" message to the vehicle's central control device, allowing the central control device to respond to the user's return operation or automatically return the vehicle. In another implementation, the information sent by the road beacon device to the associated device also includes the vehicle's NFC tag information. This information can be used to instruct the associated device to send a verification command to the cloud platform. The cloud platform then matches and verifies the NFC tag information and the vehicle's identifier based on the verification command, and determines whether to send a "allow return" command to the vehicle based on the verification result. After receiving the "allow return" command from the cloud platform, the vehicle can display a "allow return" control on the application interface.

[0069] It should be noted that the aforementioned road bead device can simultaneously send parking status information to both the vehicle and the user's device, triggering multiple return processes via both. By simultaneously triggering the return process through multiple paths, the path with the shortest response time can be used to complete the return, improving efficiency; it also avoids long waiting times for users, enhancing the user experience.

[0070] Figure 3 This is a flowchart illustrating a parking status detection method in another embodiment. This embodiment relates to an implementation of a road stud device reading NFC tag information. Based on the above embodiment, as follows... Figure 3 As shown, S101 above includes:

[0071] S201. Determine if any vehicles have entered the parking area.

[0072] Generally, parking areas on the road are pre-defined areas. These parking areas can be visually marked or virtual areas identified by road stud devices; no specific limitation is made here.

[0073] When determining whether a vehicle has entered a parking area, the road bead device can use an infrared sensor to detect it; alternatively, it can determine whether a vehicle has entered the parking area by detecting the signal transmission quality between itself and the vehicle's Bluetooth device. For example, the road bead device can broadcast a detection command via a Bluetooth communication module. When a vehicle enters the parking area, the vehicle's central control device can send detection information to the Bluetooth communication module, allowing the module to determine whether the vehicle has entered the parking area based on the communication quality of the detection information. If the communication quality of the detection information sent by the vehicle is greater than a preset threshold, then the vehicle is confirmed to have entered the parking area. The specific methods for determining entry into the parking area are not limited here.

[0074] S202. If so, the NFC tag information is read through the NFC module in the road stud device.

[0075] To avoid the road beacon device constantly reading NFC tag information, the NFC tag information can be read by the NFC module in the road beacon device after the vehicle enters the parking area.

[0076] If the NFC module reads the NFC tag information and determines that the sender of the tag information is a vehicle, then the vehicle's parking status information can be determined to be fixed-point parking.

[0077] If the road stud device determines that a vehicle has entered the parking area, and if the NFC module fails to read the NFC tag information within a preset time period, the vehicle's parking status is determined to be illegal parking.

[0078] The above-mentioned parking status detection method allows the road beacon device to determine whether a vehicle has entered the parking area before reading the NFC tag information, thus completing the approximate location of the vehicle. After the vehicle enters the parking area, the NFC tag information is read through the NFC module. This avoids the high power consumption caused by the NFC module constantly polling and reading the NFC tag information, thereby reducing the power consumption of the road beacon device, extending its battery life, and reducing its maintenance costs.

[0079] The following embodiments describe several methods by which road stud devices determine when a vehicle enters a parking area.

[0080] Figure 4This is a flowchart illustrating a parking status detection method in another embodiment. This embodiment relates to an implementation of a road stud device to determine if a vehicle has entered a parking area. The road stud device includes a metal sensor. Based on the above embodiment, as follows... Figure 4 As shown, S201 above includes:

[0081] S301. Acquire the detection data output by the metal sensor.

[0082] The aforementioned metal sensor is used to detect whether a metal object is near the road stud device. The metal sensor can be installed at the boundary of the parking area or at the vehicle's parking position; one or more metal sensors can be installed within the parking area, without limitation. The metal sensor can output detection data, which can be used to determine whether metal is near the sensor.

[0083] S302. If the detection data indicates that metal is near the metal sensor, then it is determined that a vehicle has entered the parking area.

[0084] The metal sensor can send detection data to the control unit in the road stud device, allowing the control unit to determine whether metal is near the sensor. This control unit can be a chip in the NFC module, a chip in the Bluetooth module, or a control chip independent of both the NFC and Bluetooth modules; no limitation is made here. Once the road stud device determines that metal is near the sensor, it can confirm that a vehicle has entered the parking area.

[0085] The above-mentioned parking status detection method can detect whether a vehicle has entered the parking area using a metal sensor, thus reducing the detection cost of vehicles entering the parking area.

[0086] Figure 5 This is a flowchart illustrating a parking status detection method in another embodiment. This embodiment relates to an implementation method for a road stud device to determine if a vehicle has entered a parking area. Based on the above embodiment, as follows... Figure 5 As shown, S201 above includes:

[0087] S401. Listen for the first broadcast message through the Bluetooth communication module in the road stud device; the first broadcast message is sent by the user terminal in response to the user's vehicle return instruction.

[0088] After using the vehicle, the user can park it at the designated location, then open the application on the user's device and trigger a return command on the application interface. Upon receiving the return command, the user's device can send a first broadcast message via the Bluetooth communication module. This first broadcast message informs the user that a vehicle has entered the parking area. The first broadcast message can include a vehicle identifier or be a pre-set Bluetooth broadcast message.

[0089] The Bluetooth communication module in the road stud device can listen to the aforementioned first broadcast message.

[0090] S402. If the first broadcast message is detected, it is confirmed that a vehicle has entered the parking area.

[0091] If the Bluetooth communication module detects the first broadcast message, it can confirm that a vehicle has entered the parking area.

[0092] The above-mentioned parking status detection method allows the road stud device to listen to the first broadcast message sent by the user terminal through the Bluetooth communication module. This enables the NFC module to start reading NFC tag information only after the user triggers the return command. This allows the Bluetooth road stud to more accurately control the activation time of the NFC module. Furthermore, the Bluetooth communication module consumes less power when listening. Using the above method can reduce the reading time of the NFC module and lower the power consumption of the road stud module.

[0093] Figure 6 This is a flowchart illustrating a parking status detection method in another embodiment. This embodiment relates to an implementation method for a road stud device to determine if a vehicle has entered a parking area. Based on the above embodiment, as follows... Figure 6 As shown, S201 above includes:

[0094] S501, Send a second broadcast message through the Bluetooth communication module in the road spike device.

[0095] The Bluetooth communication in the aforementioned road stud device can send a second broadcast message according to a preset broadcast period. This second broadcast message can carry the identifier of the road stud device, allowing the receiving vehicle to determine which road stud device sent the message.

[0096] The broadcast cycle can be a preset time interval, such as sending once every 1 minute; or it can be a broadcast interval set according to different time periods, such as setting a longer broadcast interval in the early morning or during periods of low vehicle usage, and setting a shorter broadcast interval during periods of low vehicle usage; the broadcast cycle can also correspond to parking areas, and different parking areas can correspond to different broadcast cycles, such as setting a shorter broadcast interval in areas with high vehicle parking density, such as office buildings or residential areas.

[0097] S502. If a response message to the second broadcast message is received, it is determined that a vehicle has entered the parking area; the response message is sent by the vehicle after receiving the second broadcast message.

[0098] Once a vehicle enters or approaches the parking area, it can receive the second broadcast message mentioned above. The vehicle can determine its distance from the road beacon based on the signal quality of the broadcast message. If the signal quality of the broadcast message is greater than a preset threshold, the vehicle is considered to have entered the parking area and can send a response message to the road beacon. Upon receiving the response message, the road beacon confirms that a vehicle has entered the parking area.

[0099] The above-mentioned parking status detection method allows the road stud device to determine whether a vehicle has entered the parking area by sending a second broadcast message. NFC detection can be activated before the user finishes using the vehicle but has not yet completed parking, or before the user's application is opened, thus reducing the time required to return the vehicle and improving the efficiency of returning the vehicle.

[0100] It should be noted that the method for determining a vehicle's entry into the parking area provided in this embodiment can be used alone or in combination of different determination methods, and no limitation is made here.

[0101] Figure 7 This is a flowchart illustrating a parking status detection method in another embodiment. This embodiment relates to an implementation of a road beacon device reading NFC tag information. The NFC module in the road beacon device may include an NFC reader and multiple NFC coils connected to the NFC reader. Based on the above embodiment, as follows... Figure 7 As shown, S101 above includes:

[0102] S601. Identify the target NFC coil corresponding to the vehicle.

[0103] Different NFC coils are positioned in different locations. To determine the target NFC coil for a vehicle entering the parking area, the distance between the vehicle and the NFC coil can be used. The road stud device can detect the NFC coil closest to the vehicle using sensors. These sensors can be infrared sensors or pressure sensors; no specific limitation is made here.

[0104] Optionally, the road stud device includes multiple metal sensors, each corresponding to an NFC coil. The metal sensors can be positioned either outside or inside the NFC coil; this is not limited. The road stud device can determine the nearest target metal sensor to the vehicle based on the detection data collected by the multiple metal sensors; then, the NFC coil corresponding to the target metal sensor is designated as the target NFC coil.

[0105] The same vehicle can correspond to one NFC coil, two NFC coils, or multiple NFC coils; there is no limitation here.

[0106] The aforementioned metal sensor can also be used to determine whether a vehicle has entered the parking area. The detection data collected by the metal sensor can be collected when a vehicle is detected entering the parking area, or after it has been determined that the vehicle has entered the parking area; there is no limitation on this.

[0107] S602, Send an NFC signal through the target NFC coil and receive NFC tag information returned by the NFC tag on the vehicle in response to the NFC signal.

[0108] After identifying the target sensor, the road stud device can control the transmission of an NFC signal through the target NFC coil via a switch. Once the NFC tag on the vehicle receives the NFC signal, it can send NFC tag information back to the road stud device. Other NFC coils in this NFC module can be in a switched-off state or can still transmit NFC signals to other vehicles; this is not limited to these options.

[0109] The above-mentioned parking status detection method uses an NFC module to connect multiple NFC coils in the road beacon device, which can reduce the number of NFC modules and lower the cost of the road beacon device. By accurately locating the target NFC coil corresponding to the vehicle, the NFC tag information can be read through the target NFC coil. This not only improves the accuracy of parking status detection by accurately reading the NFC tag information on the vehicle, but also reduces the power consumption of the road beacon device.

[0110] In one embodiment, based on the above embodiments, the road beacon device can acquire the parking posture of the vehicle. If the parking posture indicates that the vehicle is in a standing parking state, then the step of sending the parking status information to the vehicle's associated device is executed. The road beacon device can determine whether the vehicle is in a standing parking posture using sensors, such as pressure sensors. When the vehicle is parked at a fixed point, the pressure sensor can collect detection data, allowing the road beacon device to determine whether the vehicle is standing. For example, the detection data may include pressure values; when the pressure value is greater than a pressure threshold, the vehicle can be considered to be standing.

[0111] The aforementioned parking status detection method requires the road stud device to send the vehicle's designated parking information to its associated equipment only when it determines that the vehicle is in a standing parking position, thus triggering the return process. This method avoids locking the vehicle in cases of improper parking, such as when it is upside down, and improves the monitoring of the vehicle's status during return.

[0112] It should be understood that, although Figure 2-7The steps in the flowchart are shown sequentially as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified herein, there is no strict order in which these steps are executed, and they can be performed in other orders. Figure 2-7 At least some of the steps in the process may include multiple steps or multiple stages. These steps or stages are not necessarily completed at the same time, but may be executed at different times. The execution order of these steps or stages is not necessarily sequential, but may be executed in turn or alternately with other steps or at least some of the steps or stages in other steps.

[0129] Specific limitations regarding the parking status detection device can be found in the above description of the parking status detection method, and will not be repeated here. Each module in the aforementioned parking status detection device can be implemented entirely or partially through software, hardware, or a combination thereof. These modules can be embedded in the processor of the road stud device in hardware form or independently of it, or stored in the memory of the road stud device in software form, so that the processor can call and execute the corresponding operations of each module.

[0130] In one embodiment, such as Figure 11 As shown, a road stud device is provided, which is installed on the ground in a parking area. The road stud device includes a near-field communication (NFC) module and a Bluetooth communication module; the NFC module is connected to the Bluetooth communication module.

[0131] The NFC module is used to read NFC tag information; then, based on the NFC tag information, it determines whether the device that sent the NFC tag information is a vehicle; if so, it determines that the vehicle's parking status information is fixed-point parking; the Bluetooth communication module is used to send the parking status information to the vehicle's associated device, so that the associated device can trigger the vehicle return process based on the parking status information.

[0132] The specific process of reading NFC tag information, determining whether the device sending the NFC tag information is a vehicle, determining the vehicle's parking status information, and triggering the vehicle return process in the aforementioned road stud device can be found in the above method embodiments, and will not be repeated here.

The aforementioned road stud device may include a battery to power the NFC module and the Bluetooth communication module; alternatively, the aforementioned road stud device 100 may also be powered by an external power source; this is not limited here.

[0137] The road stud device provided in this embodiment is applied to road stud devices installed on the ground in a parking area. This road stud device can read NFC tag information and determine whether the device sending the NFC tag information is a vehicle. If it is determined that the NFC tag information was sent by a vehicle, the parking status information of the vehicle is determined to be fixed-point parking. The parking status information is then sent to the vehicle's associated device, which triggers a vehicle return process based on the parking status information. Since the road stud device is installed on the ground in the parking area, the parking status of vehicles is detected by the road stud device installed on the ground, eliminating the need to install detection devices on the vehicles. This avoids the need to modify a large number of vehicles and reduces the cost of parking status detection. Furthermore, since NFC communication is short-range communication, the road stud device reads the NFC tag information on the vehicle via NFC communication. The NFC tag information can only be read when the road stud device is sufficiently close to the NFC tag on the vehicle. Therefore, the road stud device in this embodiment has high accuracy in detecting vehicle parking, improving the accuracy of parking detection and thus better constraining fixed-point parking.

[0138] In one embodiment, such as Figure 12 As shown, the NFC module described above may include an NFC reader and multiple NFC coils connected to the NFC reader.

[0139] The aforementioned NFC coils can be arranged in a straight line or centered on the NFC reader; the arrangement of the NFC coils is not limited here. The distances between the aforementioned NFC coils and the NFC reader can be the same or different.

[0140] The NFC reader described above can send NFC signals through one NFC coil at the same time, or it can send NFC signals through multiple NFC coils at the same time; there is no limitation on this.

[0141] The aforementioned road stud device includes multiple NFC coils in one NFC module, which can reduce the number of NFC readers and lower the cost of the road stud device.

[0142] In one embodiment, such as Figure 13 As shown, the aforementioned road stud device may also include a metal sensor.

The metal sensor can be installed at the boundary of the parking area or at the vehicle's parking position; one or more metal sensors can be installed in the parking area, without limitation. The metal sensor can output detection data, which can be used to determine whether metal is near the metal sensor.

[0143] The aforementioned metal sensor can be connected to an NFC module, a Bluetooth communication module, or an independent control unit in the road stud device; no specific connection is made here.

[0144] The above-mentioned parking status detection method can detect whether a vehicle has entered the parking area using a metal sensor, and can determine whether a vehicle has entered the parking area in a low-cost manner.

[0145] In one embodiment, such as Figure 14 As shown, each of the aforementioned metal sensors corresponds one-to-one with an NFC coil. The metal sensors can be positioned either outside or inside the NFC coil; this is not limited. Optionally, the metal sensors are positioned within the area enclosed by the NFC coils. The road stud device can determine the target metal sensor closest to the vehicle based on the detection data collected by multiple metal sensors; then, the NFC coil corresponding to the target metal sensor is identified as the target NFC coil.

[0146] The aforementioned road stud device can accurately locate the target NFC coil corresponding to the vehicle and read the NFC tag information through the target NFC coil. This not only improves the accuracy of parking status detection by accurately reading the NFC tag information on the vehicle, but also reduces the power consumption of the road stud device.

[0147] In one embodiment, such as Figure 15 As shown, the aforementioned road stud device also includes a switch. The input terminal of the switch is connected to an NFC reader, and the output terminal is connected to multiple NFC coils.

The switch may also include a control terminal for receiving control signals. These control signals can be sent by the NFC module or by the control unit in the road stud device; this is not limited here.

[0148] The aforementioned road stud device can achieve precise control of the NFC coil through a switching switch, enabling the road stud device to match with the vehicle through the target NFC coil and read the NFC tag information on the vehicle.

[0149] In one embodiment, a road stud device is provided, including a memory, a processor, a near-field communication (NFC) module, and a Bluetooth communication module; the memory stores a computer program, and the processor executes the computer program to implement the steps of the above-described parking state detection method; the NFC module is used to read NFC tag information; and the Bluetooth communication module is used to send parking state information to the vehicle's associated device.
