Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present disclosure more clearly understood, the embodiments of the present disclosure are described in further detail below with reference to the accompanying drawings and the embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the embodiments of the disclosure and that they are not intended to limit the embodiments of the disclosure.

First, before specifically describing the technical solution of the embodiment of the present disclosure, a technical background or a technical evolution context on which the embodiment of the present disclosure is based is described. In general, in the field of online car booking travel, the current technical background is as follows: the position of the vehicle is positioned through the Bluetooth module, and the user is allowed to return the vehicle after the vehicle is parked in the fixed-point parking area. Based on the background, the applicant finds that the positioning accuracy of the bluetooth module is low through long-term scene research and experimental data collection, demonstration and verification, and the situation that the detection result that the vehicle is located in the fixed-point parking space can still be output easily under the condition that the vehicle is not parked in the fixed-point parking area is easy to occur, so that the vehicle standard parking management effect is poor. How to improve the detection precision that the vehicle was parked, the degree of accuracy that promotes the parking state of vehicle detected becomes the difficult problem that awaits a solution at present. In addition, it should be noted that the technical problems in the embodiments of the present disclosure are proposed, and the technical solutions described in the following embodiments are all provided by a great amount of creative efforts of the applicant.

The following describes technical solutions related to the embodiments of the present disclosure in combination with a scenario in which the embodiments of the present disclosure are applied.

The method for detecting the parking state provided by the embodiment of the disclosure can be applied to a system architecture as shown in fig. 1. The system architecture may include a vehicle 101, a client 102, a server 103, and a spike device 100. The vehicle 101 may be a pedal bicycle, an electric bicycle, a scooter, a motorcycle, or other non-motorized or motorized vehicles; the client 102 may be an electronic device such as a mobile phone, a tablet computer, an IPAD, or an APP software installed on the electronic device; the server 103 may be an independent server or a server cluster composed of a plurality of servers. The vehicle 101 is provided with a communication component, which can communicate with the client 102 or the server 103 in a wireless manner, for example, the client 102 can send an unlocking instruction or the like to the vehicle according to an unlocking operation of a user. In addition, the client 102 and the server 103 may communicate with each other in a wireless or wired manner. The embodiment of the present disclosure does not limit the communication method among the vehicle 101, the client 102, and the server 103. The spike device 100 may be used to detect a parking state of the vehicle 200; the spike device 100 may detect the parking state of 1 vehicle 200, or may detect the parking state of a plurality of vehicles 200, which is not limited herein. The spike device 100 may be disposed on the ground of the parking area, the spike device 100 may be attached to the surface of the parking area, or the surface of the spike device 100 may be covered with other materials, which is not limited herein.

In one embodiment, as shown in fig. 2, a method for detecting a parking state is provided, which is described by taking the method as an example applied to the spike device in fig. 1, and includes:

s101, reading the NFC label information, and determining whether the device sending the NFC label information is a vehicle.

The NFC tag information may be information stored in an NFC tag. The NFC tag may be provided on a vehicle. In order to enable the spike device to read the tag information on the vehicle, the NFC tag on the vehicle may be disposed at a position close to the ground, for example, on a pedal of the vehicle, or at the bottom of a frame of the vehicle, or may be disposed at a position of a foot rest of the vehicle, and the disposition position of the NFC tag is not limited herein. Optionally, when the vehicle stands to stop, the distance between the position of the NFC tag on the vehicle and the ground may be smaller than a preset threshold, for example, the preset threshold may be 20 centimeters. The NFC tag may be an active tag or a passive tag, which is not limited herein.

The spike device may be used to detect a parking state of a vehicle; the spike device may detect a parking state of one vehicle, and may also be used to detect parking states of a plurality of vehicles, which is not limited herein. The spike device can be arranged on the ground of a parking area, can be attached to the surface of the parking area, and can also be covered with other materials. One spike device may be disposed in the parking area, or a plurality of spike devices may be disposed in the parking area, which is not limited herein.

The spike device may include an NFC module therein, and the NFC module may include an NFC reader and at least one NFC coil. The NFC coil can be used for sending out data sent by the NFC reader and also can be used for receiving data sent by the NFC label. The NFC coil may be a single-ended antenna or a differential antenna.

The identification code of the vehicle can be stored in the NFC label information, label information corresponding to the identification code of the vehicle can also be stored, and the NFC label information can be in one-to-one correspondence with the identification code of the vehicle. The label information may be composed of numbers or a combination of numbers and letters, the combination of numbers and letters may be arranged according to a preset rule, and a specific form of the label information is not limited herein.

The spike device can send an NFC reading instruction, so that an NFC tag in an NFC receiving range of the spike device can receive the NFC reading instruction, and NFC tag information stored in the NFC tag is returned to the spike device based on the NFC reading instruction.

The spike device can automatically send a reading instruction according to a preset period so as to obtain information in the NFC label close to the spike device; or after a preset trigger condition is met, starting to send a reading instruction to acquire information in the NFC label close to the spike device; the above-mentioned reading method is not limited herein.

Due to the NFC tag close to the spike device, besides the NFC tag provided on the vehicle, it is also possible to be an NFC tag on another object, such as an NFC tag access card or the like. Therefore, the spike device needs to determine whether the device that transmitted the tag information is a vehicle after reading the tag information.

The spike device may determine whether the transmission subject of the NFC tag information is a vehicle according to a preset encoding rule of the vehicle tag information. In one implementation, the spike device may determine whether to match the number of bits of the NFC tag information of the vehicle according to the number of bits of the NFC tag information; or, the spike device may further read a character of a preset bit in the NFC tag information, determine whether the character matches the character of the preset bit in the NFC tag information of the vehicle, and may determine that the NFC tag information is sent by the vehicle when the characters match. For example, the NFC tag information on the vehicle may be in a format of "QF000000", and when the number of bits of the NFC tag information read by the track nail device is less than or more than the number of bits corresponding to the format, it may be determined that the NFC tag information is not transmitted by the vehicle; the spike device can read the first two characters in the NFC tag information, and if the read characters are not "QF", it can be determined that the NFC tag information is not sent by the vehicle.

And S102, if so, determining that the parking state information of the vehicle is fixed-point parking.

Because the reading range of the NFC module is small, the NFC label information can be read only under the condition that the vehicle is close to the spike device. Therefore, after the lane-tack device reads the NFC tag information and determines that the NFC tag information is transmitted by the vehicle, it may be determined that the parking state information of the vehicle is the fixed-point parking. If the NFC label information received by the spike device is not sent by the vehicle, the parking state is not judged. If the spike device receives the parking request of the vehicle but does not read the NFC tag information on the vehicle, it can be determined that the parking state information of the vehicle is an illegal parking. The parking request of the vehicle may be triggered by a user through an application program on a user side, or may be sent to the spike device by the spike device when the spike device detects that the vehicle is to be parked, or may be sent to the spike device by a central control device on the vehicle after a vehicle returning operation triggered by the user, where a determination manner of the parking request is not limited herein.

The parking state information of the vehicle may be identified by characters, or may be identified by numbers, which is not limited herein. For example, the parking state information of "1" may indicate that the vehicle is parked at a fixed point; the parking state information of "0" may indicate that the vehicle is illegally parked.

And S103, sending the parking state information to associated equipment of the vehicle, so as to trigger a vehicle returning process according to the parking state information through the associated equipment.

The associated device of the vehicle may be a central control device of the vehicle, or may be a user terminal used by a user who opens the vehicle. The spike device can trigger the vehicle returning process according to the parking state information through the associated device. The associated equipment can trigger a car returning process under the condition that the parking state information is the fixed-point parking; whether to trigger the vehicle returning process may also be determined according to the parking state information, the moving state of the vehicle, and the like, for example, the related device may trigger the vehicle returning process when the parking state information of the vehicle is the fixed-point parking and the vehicle is not in the moving state.

In the car returning process, the associated device can send a car locking instruction to the car lock component in the central control device, so that the car lock component can respond to the car returning operation of the user to complete car locking or automatically return the car. Or in the car returning process, the association component can also send an instruction to the user side through the cloud platform, and control the car locking component to lock the car after responding to the car returning triggering operation of the user on the user side; the specific mode and process of the above-mentioned returning process are not limited herein.

According to the method for detecting the parking state, the spike device can read the NFC label information and determine whether the device sending the NFC label information is a vehicle or not; and when the NFC label information is determined to be sent by the vehicle, determining that the parking state information of the vehicle is fixed-point parking, and further sending the parking state information to associated equipment of the vehicle so as to trigger a vehicle returning process according to the parking state information through the associated equipment. The spike device is arranged on the ground of the parking area, so that the parking state of the vehicle is detected through the spike device arranged on the ground without arranging a detection device on the vehicle, the transformation of a large number of vehicles is avoided, and the detection cost of the parking state is reduced; further, because the NFC communication is near field communication, the spike device reads the NFC label information on the vehicle in an NFC communication mode, and the NFC label information on the vehicle can be read only when the distance between the spike device and the NFC label on the vehicle is close enough, so that the detection precision of the spike device for positioning and parking the vehicle is high, the accuracy of parking detection is improved, and better constraint can be performed on fixed-point parking of the vehicle.

In the following embodiments, different implementations of the returning process will be specifically described.

In one embodiment, the spike device may send the parking state information to the vehicle, and trigger a vehicle returning process through a central control device of the vehicle. The spike device can be connected with the central control device of the vehicle through the Bluetooth communication module in a Bluetooth mode, and the parking state information is sent to the vehicle. After the vehicle receives the parking state information, it may be determined whether the vehicle is parked at a set point. When the vehicle is in the fixed-point parking state, the central control device can respond to the returning operation of the user, namely after the user performs the locking operation, the vehicle locking component on the vehicle can complete the vehicle locking.

According to the method for detecting the parking state, the user can complete the vehicle changing without executing operation on the user terminal, and the vehicle returning process of the user is simplified.

In one embodiment, the information sent by the spike device to the central control device further includes NFC tag information of the vehicle. The NFC tag information can be used for instructing the central control equipment to carry out matching verification on the NFC tag information and the identification of the vehicle, and determining whether to respond to the returning operation of the user or not based on a verification result. The identification of the vehicle can be stored in the central control device of the vehicle, and because the identification of the vehicle is in one-to-one correspondence with the NFC label information on the vehicle, the central control device can determine whether the NFC label information read by the spike device is the label information of the vehicle according to the corresponding relation between the preset NFC label information and the identification of the vehicle, and if so, the verification result can be determined to be that the verification is passed; if the NFC tag information does not match the identifier of the vehicle, it may be determined that the verification result is that the verification fails. And under the condition that the verification is passed, the central control equipment can respond to the returning operation of the user. Under the condition that the verification is not passed, the central control device may consider that the NFC tag information read by the spike device is not sent by the vehicle and cannot determine that the vehicle is in the fixed-point parking state, the central control device does not respond to a vehicle returning operation of the user, that is, after the user performs a lock closing operation, a vehicle lock component on the vehicle does not complete locking of the vehicle, and the vehicle may send a prompt message indicating that the vehicle returning fails to the user, where the prompt message may be a voice prompt message on the vehicle or a prompt message on a user side used by the user, and is not limited herein.

According to the method for detecting the parking state, the user can complete the vehicle changing without executing operation on the user terminal, and the vehicle returning process of the user is simplified. In addition, after the plurality of vehicles simultaneously receive the parking state information sent by the spike device, the parking state information of other vehicles is mistaken as the parking state information of the vehicle, and the central control device performs matching verification on the tag information, so that the condition can be avoided, and the accuracy of parking state detection is improved.

In one embodiment, the central control device may send the parking state information and the NFC tag information to the cloud platform, so that after receiving the information, the cloud platform performs matching verification on the NFC tag information and the identifier of the vehicle, and sends a vehicle returning permission instruction to the central control device of the vehicle when the verification is passed, so that the vehicle may respond to a vehicle returning operation of the user.

According to the detection method of the parking state, the NFC label western information of the vehicle and the identification of the vehicle are labeled in a matching mode through the cloud platform, and the labeling is not required to be completed in the central control device, so that the corresponding relation between the NFC label information and the identification of the vehicle is not required to be stored in the central control device, and the maintenance operation of the vehicle is simplified; in addition, when the NFC label on the vehicle is damaged or lost, a single vehicle does not need to be maintained, and the corresponding relation is updated in the cloud platform, so that the maintenance cost of the vehicle for the user is further reduced.

In one embodiment, the spike device may also transmit the parking status information to the user terminal. The spike device can send the parking state information to the user side through the Bluetooth communication module. The user side can display the control allowing the car returning to the car on the interface of the application program after receiving the parking state information. After the user triggers the control, the user side can send a vehicle returning permission to the central control device of the vehicle, so that the central control device can respond to the vehicle returning operation of the user or automatically return the vehicle. In another implementation manner, the information sent by the spike device to the association device further includes NFC tag information of the vehicle, and may be used to instruct the association device to send a verification instruction to the cloud platform, so that the cloud platform performs matching verification on the NFC tag information and the identifier of the vehicle based on the verification instruction, and then determines whether to send a vehicle returning permission instruction to the vehicle based on a verification result. After the vehicle receives the vehicle returning permission instruction sent by the cloud platform, a control for the vehicle returning permission can be displayed to a user on an interface of the application program.

It should be noted that, the spike device may also send the parking state information to the vehicle and the user side simultaneously, and trigger the vehicle returning process of multiple paths through the vehicle and the user side simultaneously. The vehicle returning process is triggered through a plurality of paths simultaneously, so that the vehicle returning can be completed by adopting the path with the shortest response time, and the vehicle returning efficiency is improved; the long-time waiting of the user can be avoided, and the user experience is improved.

Fig. 3 is a schematic flowchart of a method for detecting a parking state in another embodiment, where this embodiment relates to an implementation manner of a spike device reading NFC tag information, and on the basis of the above embodiment, as shown in fig. 3, the above S101 includes:

s201, determining whether a vehicle enters a parking area.

In general, a parking area on a road surface is an area defined in advance. The parking area may have a visually visible area identifier or may be a virtual area identified in the spike device, which is not limited herein.

When the spike device determines whether a vehicle enters a parking area, whether the vehicle enters the parking area can be detected through an infrared sensor arranged in the spike device; alternatively, the spike device may also determine whether the vehicle enters the parking area by detecting the quality of signal transmission with a bluetooth device on the vehicle. For example, the spike device may broadcast the detection instruction through the bluetooth communication module, and after the vehicle enters the parking area, the central control device on the vehicle may send the detection information to the bluetooth communication module, so that the bluetooth communication module may determine whether the vehicle enters the parking area according to the communication quality of the detection information; and if the communication quality of the detection information sent by the vehicle is greater than a preset threshold value, determining that the vehicle enters a parking area. The manner of determining the parking area entry is not limited herein.

And S202, if so, reading the NFC label information through an NFC module in the spike device.

In order to avoid that the spike device continuously reads the NFC tag information, the NFC tag information may be read by the NFC module in the spike device after the vehicle enters the parking area.

If the NFC module reads the NFC tag information and determines that the vehicle sending the tag information is a vehicle, it may be determined that the parking state information of the vehicle is fixed-point parking.

If the spike device determines that the vehicle enters the parking area, under the condition that the NFC tag information is read through the NFC module, if the NFC tag information corresponding to the vehicle is not read by the NFC module within the preset time, the parking state of the vehicle is determined to be illegal parking.

According to the detection method of the parking state, before the spike device reads the NFC label information, whether a vehicle enters a parking area or not can be determined, and the vehicle can be roughly positioned; after the vehicle gets into the parking area, NFC label information is read to the rethread NFC module, and it is great to avoid the continuous polling of NFC module to read the consumption that NFC label information leads to, has reduced the consumption of spike equipment, and it is long when prolonging the continuation of the journey of spike equipment, reduces the maintenance cost of spike equipment.

In the following embodiments, several ways of determining that a vehicle enters a parking area by a spike device will be described separately.

Fig. 4 is a schematic flowchart of a method for detecting a parking state in another embodiment, where the embodiment relates to an implementation manner of a spike device for determining that a vehicle enters a parking area, the spike device includes a metal sensor, and based on the embodiment, as shown in fig. 4, the S201 includes:

and S301, acquiring detection data output by the metal sensor.

The metal sensor is used for detecting whether metal substances are close to the spike device or not. The metal sensor can be arranged at the boundary of a parking area and can also be arranged at the parking position of the vehicle; one metal sensor may be disposed in the parking area, or a plurality of metal sensors may be disposed in the parking area, which is not limited herein. The metal sensor may output detection data, which may be used to determine whether metal is near the metal sensor.

S302, if the detection data represent that metal is close to the metal sensor, it is determined that a vehicle enters a parking area.

The metal sensor may send detection data to a control unit in the spike device such that the control unit in the spike device may determine whether metal is proximate to the metal sensor based on the detection data. The control unit may be a chip in an NFC module in the spike device, may also be a chip in a bluetooth module in the spike device, and may also be a control chip independent of the NFC module and the bluetooth communication module, which is not limited herein. After the spike device determines that metal is proximate to the metal sensor, it may be determined that a vehicle has entered the parking area.

According to the method for detecting the parking state, whether the vehicle enters the parking area or not can be detected through the metal sensor, and the detection cost of the vehicle entering the parking area is reduced.

Fig. 5 is a schematic flowchart of a method for detecting a parking state in another embodiment, where the embodiment relates to an implementation manner of a spike device for determining that a vehicle enters a parking area, and on the basis of the embodiment, as shown in fig. 5, the step S201 includes:

s401, monitoring a first broadcast message through a Bluetooth communication module in spike equipment; the first broadcast message is sent by the user end after responding to the vehicle returning instruction of the user.

After the user uses the vehicle, the user can park the vehicle at a fixed-point position, then open an application program in the user terminal, and trigger a vehicle returning command on an interface of the application program. After receiving a car returning instruction of a user, the user side can send a first broadcast message through a Bluetooth communication module in the user side. The first broadcast message may inform the user that the bluetooth spike has a vehicle entering the parking area. The first broadcast message may carry a vehicle identifier, or may be a preset bluetooth broadcast message.

The bluetooth communication module in the spike device can monitor the first broadcast message.

S402, if the first broadcast message is monitored, it is determined that a vehicle enters a parking area.

If the bluetooth communication module monitors the first broadcast message, it can be determined that a vehicle enters the parking area.

According to the method for detecting the parking state, the spike device can monitor the first broadcast message which is sent in a guard period through the Bluetooth communication module, so that the NFC module is started to read the NFC tag information after the user triggers the vehicle returning instruction, the Bluetooth spike can control the starting time of the NFC module more accurately, the power consumption of the Bluetooth communication module during monitoring is low, the reading duration of the NFC module can be reduced by adopting the method, and the power consumption of the spike module is reduced.

Fig. 6 is a schematic flow chart of a method for detecting a parking state in another embodiment, where the embodiment relates to an implementation manner of a spike device for determining that a vehicle enters a parking area, and on the basis of the above embodiment, as shown in fig. 6, the above S201 includes:

and S501, sending a second broadcast message through a Bluetooth communication module in the spike device.

The bluetooth communication in the spike device may send the second broadcast message according to a preset broadcast period. The second broadcast message may carry an identifier of the spike device, so that a vehicle receiving the second broadcast message may determine which spike device sent the second broadcast message.

The broadcast period may be a period of a preset time interval, for example, the broadcast period is transmitted once every 1 minute; the broadcast interval may be set according to different time periods, for example, a longer broadcast interval is set in the early morning or in a time period with a lower vehicle usage rate, and a shorter broadcast interval is set in a time period with a lower vehicle usage rate; the broadcast period may also correspond to a parking area, and different parking areas may correspond to different broadcast periods, for example, in an office building or a cell where vehicles are parked densely, a broadcast interval with a shorter time is set.

S502, if a response message of the second broadcast message is received, determining that a vehicle enters a parking area; the response message is sent by the vehicle after receiving the second broadcast message.

The second broadcast message may be received after the vehicle enters or approaches the parking area. The vehicle can determine the distance between the vehicle and the spike device according to the signal quality of the broadcast message, if the signal quality of the broadcast message is larger than a preset threshold value, the vehicle is considered to enter a parking area, and a response message can be sent to the spike device. After the spike device receives the response message, it can determine that a vehicle enters the parking area.

According to the method for detecting the parking state, the spike device determines whether the vehicle enters the parking area or not by sending the second broadcast message, and the NFC detection can be started before the user finishes parking the vehicle immediately after using the vehicle or finishes the vehicle but does not start the application program of the user side, so that the vehicle returning time is shortened, and the vehicle returning efficiency is improved.

It should be noted that, the manner for determining that the vehicle enters the parking area provided in the embodiment of the present disclosure may be used alone, or a combination of different determination methods may also be used, which is not limited herein.

s601, determining a target NFC coil corresponding to the vehicle.

Different NFC coils are arranged at different positions, and in order to determine a target NFC coil corresponding to a vehicle entering a parking area, the target NFC coil may be determined according to a distance between the vehicle and the NFC coil.
