[0002] In recent years, the shared bicycle and e-bike industries have flourished, making travel more convenient for citizens. However, the chaotic and haphazard parking has also hindered traffic and negatively impacted the overall image of the city. Disorderly parking is the number one problem that needs to be addressed in the development of shared two-wheelers. Adopting a designated parking system, requiring users to return vehicles in designated areas and directions, can effectively strengthen the standardized management of shared two-wheelers and rectify the chaotic parking situation.

For example, the strength of the antenna signal can be used to determine whether the vehicle is parked within a legal designated parking area. Furthermore, since the active RFID reader is located inside the vehicle, the interaction with the passive RFID tag avoids the influence of other buildings or obstacles on the interaction signal, making the antenna signal obtained by the active RFID reader more accurate. Consequently, the determined parking status of the vehicle is also more accurate, achieving the goal of precise parking management of vehicles. Attached Figure Description

[0066] 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.

[0067] 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. Generally, in the field of shared bicycles and e-bikes, the current technical background is as follows: although shared bicycles and e-bikes facilitate citizens' travel, haphazard parking obstructs traffic and affects the overall image of the city. How to regulate user parking within designated areas and directions has become a key concern in this field. Existing technologies have already proposed solutions to the problem of parking in designated areas or in designated directions. For example, for parking in designated areas (fixed-point parking), satellite single-point positioning is currently commonly used to locate vehicles. Since the positioning accuracy of a satellite single point in an open environment is only about 10 meters, the redundancy of the electronic fence at the return point must also be greater than 10 meters to ensure normal user return. The return area is limited, and satellite positioning technology is greatly affected by the environment, easily leading to weakened satellite signals or increased interference, resulting in positioning failure. Some people in the field have also used Bluetooth road beacon technology to achieve fixed-point parking. Bluetooth road beacon technology can improve the positioning accuracy to about 1 meter. However, Bluetooth signals are easily interfered with, and it is difficult to achieve accurate parking in actual operation. In addition, the coverage of Bluetooth signals is small. Generally, a Bluetooth beacon needs to be laid every 1 to 2 meters for a parking spot, which is costly.

[0068] Furthermore, for directional parking, those skilled in the art have addressed this by adding magnetometers to vehicles to measure the Earth's magnetic field. However, the magnetometer's output is susceptible to interference from its own and the surrounding magnetic field, resulting in distortion and errors such as bias error, scaling factor error, non-orthogonality error, installation error, and hard / soft magnetic field errors. These errors change with the environment, making calibration extremely difficult and hindering practical implementation of directional parking for single vehicles. Those skilled in the art have also used angle / accelerometer sensors and related inertial navigation algorithms to achieve directional parking, but angle / accelerometer sensors themselves have cumulative errors and are costly, making them difficult to implement in practice. Given this background, achieving accurate directional parking for shared bicycles, electric bicycles, and other vehicles while maintaining cost-effectiveness has become a pressing problem. It should be noted that the applicant has put in a great deal of creative effort in the technical solutions described in the following embodiments, which are based on the polarization direction of linearly polarized antennas in radio frequency technology (RFID) to determine whether a vehicle is parked in a designated location.

[0069] The technical solutions involved in the embodiments of this disclosure will be described below in conjunction with the scenarios in which they are applied.

[0070] The vehicle management method provided in this disclosure can be applied to, for example, Figure 1 The system architecture shown includes a two-wheeled vehicle terminal 101, a client terminal 102, and a server 103. The two-wheeled vehicle terminal 101 can be a non-motorized or motorized vehicle such as a bicycle, electric bicycle, scooter, or motorcycle; the client terminal 102 can be an electronic device such as a mobile phone, tablet, or iPad, or an app installed on the device; the server 103 can be a standalone server or a server cluster composed of multiple servers. The two-wheeled vehicle terminal 101 is equipped with a processor (central control processing unit) and an active RFID reader / writer. The two-wheeled vehicle terminal 101 can communicate wirelessly with the server 103. The client terminal 102 and the server 103 can communicate wirelessly or via wired connection. For example, the client terminal 102 can initiate a vehicle parking command to the server based on the user's vehicle return operation. The server 103 forwards the parking command to the two-wheeled vehicle terminal 101. After receiving the parking command, the processor in the two-wheeled vehicle terminal 101 uses the active RFID reader / writer to check whether the two-wheeled vehicle is parked legally. This disclosure does not limit the communication method between the bicycle terminal 101, the client 102, and the server 103.

[0071] In one embodiment, such as Figure 2 As shown, a method for managing transportation vehicles is provided, which can be applied to... Figure 1 The following steps are used as an example to illustrate the process of the processor in the two-wheeled vehicle end 101:

[0072] Step 201: After receiving the parking instruction from the vehicle, the antenna signal of the passive RFID tag on the roadbed equipment is obtained based on the active RFID reader on the vehicle.

[0073] The vehicles can be bicycles, electric bicycles, scooters, motorcycles, etc.; the active RFID reader is installed inside the vehicle body; the roadbed equipment refers to devices including passive RFID tags installed on the road surface within the legal parking area of ​​the vehicle. Optionally, the parking instruction received by the processor in the vehicle can be an instruction sent by the server upon receiving a parking instruction triggered by the client.

[0074] In this embodiment, based on a usage scenario, for example, a user triggers a parking command for a vehicle via a client. The client sends the parking command to the server. The server, based on the vehicle's identifier in the parking command, sends the parking command to the processor of the corresponding vehicle. After receiving the parking command, the vehicle's processor controls an active RFID reader to detect whether an RFID tag exists within its signal coverage area. At this time, the active RFID reader sends a search signal. A passive RFID tag on a roadside device within its signal coverage area receives the search signal and is awakened, responding to the search signal by sending its own antenna signal. In this case, the active RFID reader acquires the antenna signal sent by the passive RFID tag.

[0075] Step 202: Determine whether the parking status of the vehicle is legal based on the antenna signal and the preset signal strength threshold.

[0076] The parking status of vehicles includes information such as the vehicle's parking location and direction.

[0077] In this embodiment, the active RFID reader receives the antenna signal transmitted by the passive RFID tag and obtains the signal strength of the antenna signal. The processor then determines whether the vehicle is parked in a legal location, i.e., whether the vehicle's parking status is legal, based on the signal strength of the antenna signal and a preset signal strength threshold. For example, if the processor determines that the current antenna signal strength meets the preset signal strength threshold, it determines that the vehicle is parked in a legal location and in a legal parking direction, i.e., the vehicle's parking status is legal. Optionally, the processor can also obtain tag information of the passive RFID tag based on the antenna signal, such as tag identification and tag location; this embodiment does not limit this.

[0078] In the aforementioned vehicle management method, after receiving a parking instruction from the vehicle, a processor installed inside the vehicle acquires the antenna signal from the passive RFID tag on the roadside equipment using an active RFID reader on the vehicle. Based on the antenna signal and a preset signal strength threshold, the processor determines whether the vehicle's parking status is legal. In this scheme, the antenna signal is generated by the interaction between the active RFID reader and the passive RFID tag. The strength of this antenna signal, to a certain extent, indicates the distance between the active RFID reader and the passive RFID tag. Based on the relationship between the antenna signal and the preset signal strength threshold, the distance between the active RFID reader and the passive RFID tag can be determined, thereby determining whether the vehicle's parking status is legal. For example, the strength of the antenna signal can determine whether the vehicle is parked within a legal designated parking area. Furthermore, because the active RFID reader is installed inside the vehicle, the interaction with the passive RFID tag avoids the influence of other buildings or obstacles on the interaction signal, making the antenna signal obtained by the active RFID reader more accurate. Therefore, the determined parking status of the vehicle is also more accurate, achieving the goal of precise vehicle parking management.

[0079] Active RFID readers on vehicles can automatically identify antenna signals of other antennas within their signal coverage area. In one optional embodiment, step 201 above, which involves acquiring antenna signals of passive RFID tags on roadside equipment based on the active RFID reader on the vehicle, includes:

[0080] The antenna signal of the second linearly polarized antenna on the passive RFID tag is obtained based on the first linearly polarized antenna in the active RFID reader.

[0081] Since the passive RFID tags on the roadbed equipment are fixed tags, the polarization direction of the second linearly polarized antenna is fixed. For example, the fixed direction can be a specified horizontal direction, such as the north-south direction, the east-west direction, etc.; or, the fixed direction can also be a vertical direction. In this embodiment, the polarization direction of the second linearly polarized antenna is not limited.

[0082] In this embodiment, in one scenario, when a user parks a vehicle in a legal position with a legal parking direction, the first linearly polarized antenna in the active RFID reader on the vehicle and the second linearly polarized antenna on the passive RFID tag are aligned with each other and have the same polarization direction. At this time, the active RFID reader can acquire the antenna signal transmitted by the second linearly polarized antenna with sufficient signal strength. If there is a deviation in the polarization direction between the first linearly polarized antenna in the active RFID reader on the vehicle and the second linearly polarized antenna on the passive RFID tag, the active RFID reader may acquire the antenna signal transmitted by the second linearly polarized antenna with weaker signal strength, or it may not acquire the antenna signal at all. This embodiment does not limit this.

[0083] In this embodiment, the processor obtains the antenna signal of the second linearly polarized antenna on the passive RFID tag through the first linearly polarized antenna in the active RFID reader. Since the active RFID reader is located inside the vehicle, the method of obtaining the antenna signal is relatively simple and is not easily affected by other large buildings or obstacles. The error generated by the RFID reader in obtaining the signal is small.

[0084] After the processor acquires the antenna signal from the second linearly polarized antenna on the passive RFID tag via the active RFID reader, it can determine the parking status of the vehicle based on the antenna signal. In one optional embodiment, such as Figure 3 As shown, step 202 above, determining whether the parking status of the vehicle is legal based on the antenna signal and a preset signal strength threshold, includes:

[0085] Step 301: Determine the positional relationship between the first linearly polarized antenna and the second linearly polarized antenna based on the signal strength and a preset signal strength threshold.

[0086] In this embodiment, based on the principle that two linearly polarized antennas can only receive antenna signals with sufficient signal strength when they are aligned and have the same polarization direction, the processor determines the positional relationship between the first and second linearly polarized antennas according to the received antenna signal strength. Optionally, the positional relationship between the first and second linearly polarized antennas includes several cases such as being aligned and having the same polarization direction, having different polarization directions, or not being in the same signal coverage area.

[0087] Optionally, in one optional embodiment, the signal strength threshold can be set to multiple values. For example, the signal strength threshold includes a first threshold. If the signal strength of the antenna signal is greater than or equal to the first threshold, it indicates that the antenna signal is being received normally. In this case, the positional relationship between the first linearly polarized antenna and the second linearly polarized antenna is determined to be that they are aligned and have the same polarization direction. A schematic diagram showing the alignment and consistent polarization direction of the first linearly polarized antenna and the second linearly polarized antenna can be found in [reference needed]. Figure 4 As shown; optionally, the signal strength threshold may further include a second threshold, wherein the second threshold is less than the first threshold. If the signal strength of the antenna signal is less than the first threshold and the signal strength is greater than the second threshold, it indicates that the signal strength of the antenna signal acquired by the active RF reader is weak. In this case, the positional relationship between the first linearly polarized antenna and the second linearly polarized antenna is determined to be that their polarization directions are inconsistent. A schematic diagram illustrating the inconsistent polarization directions between the first linearly polarized antenna and the second linearly polarized antenna can be found in the diagram. Figure 5As shown; Optionally, if the signal strength of the antenna signal is less than the second threshold, it indicates that the signal strength of the antenna signal obtained by the active RF reader is very weak, or even that the antenna signal is almost not obtained. In this case, the positional relationship between the first linearly polarized antenna and the second linearly polarized antenna is determined to be that they are not in the same signal coverage area. This embodiment does not limit this.

[0088] Step 302: Determine whether the parking status of the vehicle is legal based on the location relationship.

[0089] In this embodiment, the processor determines whether the parking status of the vehicle is legal based on the several positional relationships determined in step 301 above.

[0090] Optionally, in one embodiment, if the first and second linearly polarized antennas are aligned and have the same polarization direction, this indicates that the vehicle is properly placed in the parking position and the parking direction meets the requirements. For example, the vehicle is parked directly above the roadside equipment, and the parking direction meets the requirements. In this case, the parking status of the vehicle is determined to be legal. Optionally, when the polarization directions of the first and second linearly polarized antennas are consistent, the passive RFID tag can transmit antenna signals through the second linearly polarized antenna and successfully return tag information. Optionally, if the first and second linearly polarized antennas have inconsistent polarization directions, this indicates that the vehicle may be placed within the legal parking area of ​​the parking position. However, if the parking location or direction does not meet the requirements, for example, the vehicle is parked directly above the roadbed equipment, but the parking direction is opposite to the requirements, then the parking status of the vehicle is determined to be illegal. Optionally, in this case, the passive RFID tag can send antenna signals through the second linear polarized antenna, but cannot return tag information. Optionally, the positional relationship between the first linear polarized antenna and the second linear polarized antenna is that they are not in the same signal coverage area. In this case, it indicates that the vehicle is not placed within the legal parking area, that is, it is not parked within the parking area with roadbed equipment. In this case, the parking status of the vehicle is determined to be illegal. In this case, the passive RFID tag may not be able to respond to the search signal sent by the active RFID reader. This embodiment does not limit this.

[0091] In this embodiment, based on the principle of linearly polarized antenna communication, the positional relationship between the first and second linearly polarized antennas is determined according to the antenna signal strength. This positional relationship is then used to determine whether the parking status of the vehicle is legal. This method is simple and accurate in determining the parking status of the vehicle. Furthermore, the active RFID reader installed inside the vehicle and the passive RFID tag installed on the roadbed equipment are both low-cost. This method achieves precise directional and fixed-point parking while controlling the cost of vehicle management.

[0092] To further achieve the purpose of directional and fixed-point parking, in one optional embodiment, the method further includes:

[0093] If the vehicle's parking status is invalid, an alert message will be output, prompting the user to change the vehicle's parking location and / or parking direction.

[0094] In this embodiment, the processor can send the reminder message to the client; alternatively, the processor can also send the reminder message to the server, so that the server forwards the reminder message to the client. Optionally, the reminder message may include a diagram showing the legal parking location range and legal parking direction of the vehicle, so that the user can park legally based on the diagram and return the vehicle smoothly. This embodiment does not limit this aspect.

[0095] In this embodiment, the processor can also output reminder messages to prompt the user to change the parking location and / or parking direction of the vehicle, thereby completing the smooth return of the vehicle, standardizing the parking status of the vehicle, and avoiding the problem of messy parking.

[0096] The following describes an embodiment of this disclosure using a specific travel scenario; see details below. Figure 6 As shown, the method includes the following steps:

[0097] Step 601: The user triggers a vehicle return instruction based on the client. The client forwards the vehicle return instruction to the server. The server sends a parking instruction to the vehicle's processor based on the vehicle return instruction.

[0098] Step 602: After receiving the parking instruction of the vehicle, the processor acquires the antenna signal of the second linear polarized antenna on the passive RFID tag based on the first linear polarized antenna in the active RFID reader.

[0099] Step 603: Determine the positional relationship between the first linearly polarized antenna and the second linearly polarized antenna based on the signal strength and a preset signal strength threshold.

[0100] Step 604: If the positions of the first linear polarized antenna and the second linear polarized antenna are aligned, then the parking status of the vehicle is determined to be legal.

[0101] Step 605: If the positions of the first linearly polarized antenna and the second linearly polarized antenna are not aligned, or if the positions of the first linearly polarized antenna and the second linearly polarized antenna are not within the same signal coverage area, then the parking status of the vehicle is determined to be illegal.

[0102] Step 606: If it is determined that the parking status of the vehicle is legal, then perform the vehicle locking operation;

[0103] Step 607: If the parking status of the vehicle is invalid, output a reminder message. The reminder message is used to prompt the vehicle to change its parking location and / or parking direction.

[0104] In this embodiment, the processor determines the positional relationship between the first linearly polarized antenna and the second linearly polarized antenna based on the antenna signal strength, and then determines whether the parking status of the vehicle is legal based on the positional relationship. This method is simple and accurate in determining the parking status of the vehicle. Moreover, the active RFID reader installed inside the vehicle and the passive RFID tag installed on the roadbed equipment are both low-cost. While achieving precise directional and fixed-point parking, the cost of vehicle management is controlled.

[0105] It should be understood that, although Figure 2-6 The 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 2-6 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.

[0106] In one embodiment, such as Figure 7 As shown, a vehicle 1 is provided, which includes a processor 11 and an active radio frequency reader 12.

[0107] The processor 11 is used to control the active RFID reader 12 to acquire the antenna signal of the passive RFID tag 21 on the roadbed equipment 2 after receiving the parking instruction of the vehicle 1.

[0108] The processor 11 is also used to determine whether the parking status of the vehicle 1 is legal based on the antenna signal and a preset signal strength threshold.

[0109] Among them, such as Figure 7 As shown, vehicle 1 can be a two-wheeled vehicle such as a bicycle or electric vehicle. Taking an electric vehicle as an example, the processor 11 and the active RFID reader 12 are located inside vehicle 1, as shown in the figure, and can be simultaneously installed under the vehicle body. Optionally, the processor 11 and the active RFID reader 12 can also be separately installed inside the vehicle body. The processor 11 and the active RFID reader 12 can be connected via wired or wireless means.

[0110] In this embodiment, processor 11 performs the above-described... Figures 2-5 The management method for vehicles provided in this embodiment will not be described in detail here.

[0111] In this embodiment, the linearly polarized antenna has a fixed antenna polarization direction. When the antenna polarization directions of the two linearly polarized antennas are consistent, an antenna signal that meets the signal strength requirement is generated. Based on this principle, the antenna signal generated by the second linearly polarized antenna is obtained through the active RFID reader antenna on the vehicle. The processor can determine whether the directions of the first and second linearly polarized antennas are consistent based on the relationship between the antenna signal and the preset signal strength threshold, that is, whether the parking status of the vehicle meets the requirements. This method can simply and effectively determine the parking position and parking direction of the vehicle, realizing the accurate and legal parking of the vehicle.

[0112] In one alternative embodiment, such as Figure 8 As shown, the active RFID reader 12 includes a first linearly polarized antenna 121; the passive RFID tag 21 includes a second linearly polarized antenna 211.

[0113] The processor 11 is used to control the active RFID reader 12 to acquire the antenna signal of the second linearly polarized antenna 211 in the passive RFID tag 21 through the first linearly polarized antenna 121 after receiving the parking instruction of the vehicle 1.

[0114] Among them, reference Figure 8 As shown, after receiving a parking instruction from vehicle 1, processor 11 controls active RFID reader 12 to identify passive RFID tags within the signal coverage area. Optionally, a search signal is transmitted via first linearly polarized antenna 121. Passive RFID tag 21 responds to this search signal, waking up second linearly polarized antenna 211 to transmit an antenna signal. Processor 11 acquires this antenna signal via active RFID reader 12. Generally, the distance between active RFID reader 12 and passive RFID tag 21 is less than 1 meter.

[0115] In this embodiment, a first linearly polarized antenna is provided in the active RFID reader, and a second linearly polarized antenna is provided in the passive RFID tag. Based on the fact that the antenna polarization directions of the two linearly polarized antennas are consistent, an antenna signal with sufficient signal strength is generated. The antenna signal transmitted by the second linearly polarized antenna is acquired. Since the active RFID reader and the passive RFID tag are close to each other, the antenna signal is not easily affected by external environmental interference.

[0116] In one alternative embodiment, such as Figure 9 As shown, the active RFID reader 12 also includes a communication module 122 and a read / write module 123;

[0117] Communication module 122 is used to receive control commands sent by processor 11;

[0118] The read / write module 123 is used to acquire the antenna signal of the second linearly polarized antenna 211 in the passive RFID tag 21 through the first linearly polarized antenna 121.

[0119] The communication module 122 is also used to send antenna signals to the processor 11;

[0120] The processor 11 is used to determine whether the parking status of the vehicle 1 is legal based on the antenna signal and a preset signal strength threshold.

[0121] In this embodiment, after receiving the parking instruction from the vehicle 1, the processor sends a control instruction to the communication module 122 of the active RFID reader 12. The communication module 122 is communicatively connected to the read / write module 123. After receiving the control instruction, the communication module 122 transmits the control instruction to the read / write module 123. The read / write module 123 reads the antenna signal of the second linearly polarized antenna 211 in the passive RFID tag 21 through the first linearly polarized antenna 121, and sends the antenna signal to the processor 11 through the communication module 122, so that the processor 11 performs corresponding operations according to the antenna signal.

[0122] In one optional embodiment, the processor 11 is configured to determine the positional relationship between the first linearly polarized antenna 121 and the second linearly polarized antenna 211 based on the signal strength and a preset signal strength threshold; and to determine whether the parking status of the vehicle 1 is legal based on the positional relationship.

[0123] In this embodiment, the processor 11 determines whether the parking status of the vehicle 1 is legal, as described above. Figures 2-5 The vehicle management method provided in this embodiment will not be described in detail here.

[0124] In one optional embodiment, the processor 11 is configured to determine that the positional relationship is that the first linearly polarized antenna 121 and the second linearly polarized antenna 211 are aligned when the signal strength is greater than or equal to a first signal strength threshold.

[0125] The processor 11 is used to determine the positional relationship as follows when the signal strength is less than a first signal strength threshold and greater than a second signal strength threshold: the directions of the first linearly polarized antenna 121 and the second linearly polarized antenna 211 are not consistent.

[0126] The processor 11 is used to determine the positional relationship when the signal strength is less than a second signal strength threshold, that the position of the first linearly polarized antenna 121 and the position of the second linearly polarized antenna 211 are not within the same signal coverage area.

[0127] In this embodiment, the processor 11 determines whether the parking status of the vehicle 1 is legal, as described above. Figures 2-5 The vehicle management method provided in this embodiment will not be described in detail here.

[0128] In one alternative embodiment, the processor 11 is configured to determine that the parking status of the vehicle 1 is legal when the positions of the first linearly polarized antenna 121 and the second linearly polarized antenna 211 are aligned.

[0129] The processor is configured to determine that the parking status of the vehicle 1 is invalid when the positions of the first linearly polarized antenna 121 and the second linearly polarized antenna 211 are not aligned, or when the positions of the first linearly polarized antenna 121 and the second linearly polarized antenna 211 are not within the same signal coverage area.

[0130] In this embodiment, the processor 11 determines whether the parking status of the vehicle 1 is legal, as described above. Figures 2-5 The vehicle management method provided in this embodiment will not be described in detail here.

[0131] In one embodiment, such as Figure 10 As shown, a roadbed device 2 is provided, which includes a plurality of passive radio frequency tags 21;

[0132] The passive RFID tag 21 is used to transmit an antenna signal when it receives a search signal sent by the active RFID reader 12 of the vehicle 1, so that the processor 11 of the vehicle 1 can determine whether the parking status of the vehicle 1 is legal based on the antenna signal and a preset signal strength threshold.

[0133] The roadbed equipment 2 is set within the legal parking area of ​​the vehicle. The roadbed equipment may include multiple passive radio frequency tags 21. Within the legal parking area, the multiple passive radio frequency tags 21 may be arranged according to agreed rules, such as being arranged at equal intervals or according to the designated position of the parking space. This embodiment does not limit the arrangement method.

[0134] In this embodiment, the passive RFID tag 21 is activated upon receiving a search signal from the active RFID reader 12. In response to the search signal, it sends an antenna signal, which the active RFID reader 12 receives. This allows the processor 11 to determine whether the parking status of the vehicle 1 is legal based on the antenna signal and a preset signal strength threshold. The vehicle management method executed by the processor 11 can be found in [reference needed]. Figures 2-5 The provided embodiments will not be described in detail here.

[0135] In this embodiment, the roadbed equipment includes passive radio frequency tags, which do not require power supply settings and have a lower cost.

[0136] In one alternative embodiment, such as Figure 11 As shown, the passive RFID tag 21 includes a second linearly polarized antenna 211 and an RFID chip 212;

[0137] The radio frequency chip 212 is used to power the second linearly polarized antenna 211 when it receives a search signal sent by the active radio frequency reader 12 of the vehicle 1, so that the second linearly polarized antenna 211 transmits antenna signals.

[0138] The passive RFID tag 21 includes a second linearly polarized antenna 211 and an RFID chip 212. The second linearly polarized antenna 211 and the RFID chip 212 can be connected by wire or wireless means. Since the road-based equipment is a passive RFID tag, when the RFID chip 212 receives a search signal sent by the active RFID reader 12 of the vehicle 1, it automatically supplies power to the second linearly polarized antenna 211, thereby enabling the second linearly polarized antenna 211 to send an antenna signal so that the active RFID reader of the vehicle can obtain the antenna signal and perform corresponding operations.

[0139] In this embodiment, the fixed-point and directional parking function of the vehicle is realized by using the first linear polarized antenna in the active RFID reader and the second linear polarized antenna in the passive RFID tag. Moreover, the RFID technology has a long communication distance and low cost.

[0140] In one embodiment, such as Figure 12 As shown, a vehicle management system is provided, which includes... Figures 5-7 The provided means of transportation 1 and Figures 8-9 2. Roadbed equipment provided.

[0141] The vehicle refers to a vehicle that includes a processor and an active RFID reader / writer, which can be a two-wheeled vehicle such as a bicycle, electric vehicle, or motorcycle, as described above. Figures 5-7 In the provided embodiment, the active RFID reader in the vehicle includes a first linearly polarized antenna, a communication module, and a read / write module. As described above. Figure 8 and Figure 9 An embodiment of the provided roadbed equipment may include a passive RFID tag, which includes a second linearly polarized antenna and an RFID chip. When a vehicle and the roadbed equipment are within the same signal coverage area, an active RFID reader in the vehicle can automatically identify the passive tag information in the roadbed equipment. When the directions of the first and second linearly polarized antennas are aligned, the active RFID reader receives an antenna signal that meets the signal strength threshold, thereby determining that the vehicle has met the requirements for directional parking and is parked in a legal location.

[0142] In this embodiment, the linearly polarized antenna has a fixed antenna polarization direction. When the antenna polarization directions of the two linearly polarized antennas are consistent, an antenna signal that meets the signal strength requirement is generated. Based on this principle, the antenna signal generated by the second linearly polarized antenna is obtained through the active RFID reader antenna on the vehicle. The processor can determine whether the directions of the first and second linearly polarized antennas are consistent based on the relationship between the antenna signal and the preset signal strength threshold, that is, whether the parking status of the vehicle meets the requirements. This method can simply and effectively determine the parking position and parking direction of the vehicle, realizing the accurate and legal parking of the vehicle.

[0148] In one optional embodiment, the determining module 02 is configured to determine the positional relationship as follows: when the signal strength is greater than or equal to a first signal strength threshold, the directions of the first linearly polarized antenna and the second linearly polarized antenna are consistent; when the signal strength is less than the first signal strength threshold and greater than the second signal strength threshold, the directions of the first linearly polarized antenna and the second linearly polarized antenna are inconsistent; and when the signal strength is less than the second signal strength threshold, the positional relationship as follows: the positions of the first linearly polarized antenna and the second linearly polarized antenna are not within the same signal coverage area.

[0149] In one optional embodiment, the determining module 02 is configured to determine that the parking status of the vehicle is legal if the positions of the first linearly polarized antenna and the second linearly polarized antenna are aligned; and to determine that the parking status of the vehicle is illegal if the positions of the first linearly polarized antenna and the second linearly polarized antenna are not aligned, or if the positions of the first linearly polarized antenna and the second linearly polarized antenna are not within the same signal coverage area.

[0150] In one alternative embodiment, such as Figure 14 As shown, the vehicle management device also includes an output module 03;

[0151] Output module 03 is used to output a reminder message when the parking status of the vehicle is illegal. The reminder message is used to prompt the vehicle to change its parking position and / or parking direction.
