Description

Technical Field

[0001] This application relates to the field of ranging technology, and in particular to a UWB ranging method, device, equipment, medium and system for gate entry and exit. Background Technology

[0002] Ultra Wide Band (UWB) technology is a wireless carrier communication technology. Based on UWB's precise ranging capabilities, UWB is currently widely used in various scenarios, such as in gate access payment scenarios, where UWB technology is used for ranging and transactions.

[0003] Due to the hardware characteristics of UWB devices, when one device sends data, multiple devices can receive it. However, when multiple devices send data simultaneously, air channel conflicts can occur, causing the receiving end to be unable to receive the data correctly.

[0004] Currently, the UWB ranging method for gate entry and exit mainly reduces the probability of ranging conflicts through time-division multiplexing. However, this method has a high failure rate when there is a large amount of air interface data, and it will basically fail. Furthermore, the ranging loop in time-division multiplexing is followed by the transaction loop, in which the transaction takes up a lot of time, usually requiring 300-500ms to complete the data transaction. This stage cannot be interfered with by other ranging messages or other transaction messages, otherwise it will lead to transaction failure or affect the system's response timeliness. This may result in delayed response to other ranging messages, and the ranging efficiency is very low. Summary of the Invention

[0065] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0066] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0067] The embodiments of this application will be explained below in conjunction with application scenarios. The method provided in the embodiments of this application can be applied to application scenarios of contactless payment for vehicles passing through turnstiles or other many-to-many ranging transaction scenarios. For example, the executing entity of the method provided in the embodiments of this application can be a terminal device of the turnstile for ranging and transaction, such as an ultra-wideband (UWB) device. In actual ranging, it can be one or multiple UWB devices. More specifically, the UWB device can be a UWB base station. The following description uses a UWB device as the executing entity of the method provided in the embodiments of this application.

[0068] Figure 1 This is a schematic diagram of a possible scenario provided for an embodiment of this application, such as... Figure 1 As shown, the system includes entrance and exit turnstiles, with a small distance between them, such as 5 meters or even less. Understandably, in contactless payment applications, UWB devices can be used for ranging and transaction processing. The ranging specifications for UWB devices follow the FIRA standard and the 802.15.4 standard. Due to the hardware characteristics of UWB devices, when one device transmits data, multiple devices can receive it. However, when multiple devices transmit data simultaneously, air channel collisions can occur, causing the receiving end to fail to receive data correctly. In situations such as... Figure 1 In certain application scenarios, when the entrance gate and exit gate are close to each other, the TAG device may simultaneously measure distances and conduct transactions on both the entrance and exit networks of the gate when entering or exiting the gate channel. This can lead to mutual interference between the two networks, causing the entire system to malfunction.

[0069] Combination Figures 2a-2c As shown, in related technologies, a time-series scheduling-based ranging method is used in the ranging round. All ranging devices are controlled by a controller to send different ranging frames or ranging result report frames at different times. In block-based mode, the time interval between two consecutive ranging rounds is constant. Figure 2a and Figure 2cAs shown, in the ranging and transaction process of UWB devices, multiple time slots are divided. The first few slots constitute the ranging phase, and the ranging method is a time-scheduled ranging loop based on block mode. After ranging is completed, the data transaction phase begins, which includes a wake-up selection phase, a data transaction phase, and a transaction termination phase. The wake-up selection phase involves selecting a device that matches the ranging distance from several external tags (e.g., TAG1, TAG2) for data transaction. The data transaction phase involves conducting a data transaction with the selected tag. The transaction termination phase involves sending a sleep command after the data transaction is completed, causing the tag to pause data transaction to save power.

[0070] Specifically, in the block-based ranging methods described above, a hopping mechanism is typically used to reduce the probability of ranging conflicts, which is achieved through time-division multiplexing. For example... Figure 2b As shown, the time is divided into several equal intervals, each block is divided into several rounds, and each round is divided into several slots; the starting point of each ranging measurement is aligned with the time node of the round. Figure 2b In this model, for 5 ranging blocks (index values ​​Index0, Index1, Index2, Index3, and Index4), each block is divided into 4 rounds (index values ​​Index0, Index1, Index2, and Index3), where the gray area represents the ranging rounds. In the hopping mechanism, a round is selected for ranging for each block, and different rounds can be selected for different blocks. This reduces conflicts with other networks to some extent. For example, ranging network NET1 uses 0, 1, 0, 3, 1, while NET2, which is also ranging, uses 2, 2, 2, 2, 2. In this case, the two ranging networks will not generate ranging data at the same time, avoiding overlap, and the probability of ranging conflicts in each round will be relatively reduced. However, when multiple NETs are ranging simultaneously, the probability of round conflicts will increase. According to the mathematical probability algorithm abstraction: among N rounds (1 to N), a random round is selected M times, where the cases with the same numbers represent network ranging conflicts. Therefore, the above ranging method has a high failure rate when there is a lot of air interface data, and it will basically fail. When the channel is congested, it is difficult to select an idle ranging time. When all rounds are occupied, channel conflicts between network communications will be unavoidable.

[0071] Furthermore, by integrating the UWB transaction process, the payment process for TAG devices is realized using a POS (Point of Sales) network. The POS network includes an inbound POS network and an outbound POS network. In this embodiment, the inbound network of the gate includes the inbound POS network, and the outbound network includes the outbound POS network. Figure 2c The diagram shows a timing diagram of a turnstile (such as an entrance turnstile). Assuming there are three TAG devices, under normal application conditions, data transactions are performed after distance measurement. The entire entrance POS will continuously send and receive data. If there is also an exit POS nearby, the exit POS will have virtually no idle time (the entrance POS has no idle time) available for distance measurement. For contactless payment projects, such as... Figure 2c Following the ranging round is the transaction round, which takes up a significant amount of time, typically 300-500ms to complete. This stage cannot be interfered with by other ranging or transaction messages (inbound POS cannot be interfered with by outbound POS), otherwise it will lead to transaction failure or affect the system's responsiveness. Clearly, the hopping mechanism is not suitable for contactless payment projects.

[0072] In view of this, this application proposes a UWB ranging method, apparatus, device, medium, and system to replace the time-division multiplexing method used in related technologies to reduce the probability of ranging conflicts. In this embodiment, two different frequency UWB channels are used. Depending on whether the current location of the TAG device is at the gate entrance or the gate exit, different UWB channels are used for UWB ranging. The channels do not interfere with each other, thereby achieving the purpose of seamless payment function for entering and exiting the station. This effectively improves the ranging and transaction efficiency of gate entry and exit, especially when the distance between the entrance and exit gates is relatively short.

[0073] The technical solution of this application and how it solves the above-mentioned technical problems will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that these specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0074] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for analysis, data stored, data displayed, etc.) involved in this application are all information and data authorized by the user or fully authorized by all parties. Furthermore, the collection, use and processing of the relevant data must comply with relevant laws, regulations and standards, and corresponding operation entry points are provided for users to choose to authorize or refuse.

[0075] Figure 3This is a flowchart illustrating a UWB ranging method for gate entry and exit provided in an embodiment of this application. This embodiment uses two different frequency UWB channels to achieve UWB ranging. Optionally, the first UWB channel is used in the gate's entry network, and the second UWB channel is used in the gate's exit network.

[0076] In this embodiment, the first UWB channel and the second UWB channel have different frequencies, that is, their wireless communication frequencies are different.

[0077] In one implementation, the first UWB channel uses the CH5 channel and the second UWB channel uses the CH8 channel. That is, the ranging transaction between the TAG device and the inbound network uses the CH5 channel, and the ranging transaction with the outbound network uses the CH9 channel. In another implementation, the first UWB channel uses the CH8 channel and the second UWB channel uses the CH5 channel. That is, the ranging transaction between the TAG device and the inbound network uses the CH9 channel, and the ranging transaction with the outbound network uses the CH5 channel.

[0078] Understandably, CH5 and CH8 are the channels that UWB devices can use for ranging. The frequency of CH5 is 2.432 GHz, and the frequency of CH8 is 2.447 GHz. The wireless communication frequencies of the two channels are quite different, so the two channels will not interfere with each other. The transmission and reception of data on one channel will not affect the other channel.

[0079] It should be noted that the specific forms of the first and second UWB channels described above are merely examples of this embodiment and not specific limitations. In addition to the CH5 and CH8 channels mentioned above, other channel resources can also be used as communication technology continues to develop.

[0080] like Figure 3 As shown, the method provided in this embodiment includes steps S301 and S302:

[0081] Step S301: If the current location area of ​​the TAG device belongs to the first location area where the gate entrance is located, then perform a first distance measurement on the TAG device according to the first UWB channel, and obtain the passage payment fee of the TAG device according to the first distance measurement result.

[0082] Step S302: If the current location area of ​​the TAG device belongs to the second location area where the exit of the gate is located, then the TAG device is subjected to a second ranging based on the second UWB channel, and the passage payment fee of the TAG device is obtained based on the second ranging result.

[0083] Combination Figure 1 As shown, Figure 1Location area A is the first location area where the entrance of the turnstile is located, location area B is the second location area where the exit of the turnstile is located, and location area C is any other location area that does not belong to the first or second location areas. In this embodiment, location area A is the location area close to the entrance of the turnstile, location area B is the location area close to the exit of the turnstile, and location area C is a location further away from the entrance and exit of the turnstile compared to location areas A and B, typically outside the location range of location areas A and B.

[0084] It should be noted that those skilled in the art can adapt the specific ranges of the first and second position areas by combining practical applications and existing technologies. For example, the first and second position areas can be set according to the specific locations of the gate's entrance and exit.

[0085] It is understood that in this embodiment, the first position area and the second position area do not overlap, that is, the first position area and the second position area are two different areas.

[0086] Compared to related technologies, the ranging methods for TAG devices at turnstiles, which use time-division multiplexing to reduce the probability of ranging conflicts, can easily lead to transaction failures or affect system response when there is a lot of air interface data. This embodiment uses two different frequency UWB channels. Depending on whether the TAG device is currently located at the turnstile entrance or exit, the corresponding UWB channel is used for UWB ranging. The channels do not interfere with each other, thereby achieving the purpose of seamless payment function for entering and exiting the turnstile. This effectively improves the ranging and transaction efficiency of turnstiles, especially when the distance between entrance and exit turnstiles is close.

[0087] Figure 4a and Figure 4b This is a flowchart illustrating another UWB ranging method for gate entry and exit provided in this application embodiment. Based on the above embodiment, this embodiment receives broadcast messages from TAG devices and identifies the current location area of ​​the TAG device according to the RSSI (Received Signal Strength Indicator) of the broadcast messages to accurately obtain the location of the TAG device, providing data support for UWB ranging. Specifically, in addition to steps S301 and S302, before step S301 performs a first ranging on the TAG device based on a first UWB channel, or step S302 performs a second ranging on the TAG device based on a second UWB channel, the method further includes steps S401 and S402 or step S402'.

[0088] Step S401: Obtain the broadcast message sent by the TAG device;

[0089] Step S402: Based on the Signal Strength Indication (RSSI) of the broadcast message, identify whether the current location area of ​​the TAG device belongs to the first location area where the gate's entrance is located; if so, execute step S301 to perform a first ranging on the TAG device based on the first UWB channel, and obtain the passage payment fee of the TAG device based on the first ranging result; otherwise, end the process, and the ranging can be further completed using existing technology.

[0090] or,

[0091] Step S402': Based on the signal strength indicator RSSI of the broadcast message, identify whether the current location area of ​​the TAG device belongs to the second location area where the exit of the gate is located. If so, execute step S302 to perform a second ranging on the TAG device according to the second UWB channel, and obtain the passage payment fee of the TAG device according to the second ranging result; otherwise, end the process, and the existing technology can be used to further complete the ranging.

[0092] In this embodiment, before using the first UWB channel or the second UWB channel for ranging, the TAG device will first broadcast. The UWB device can determine the distance between the signal point and the receiving point through the RSSI signal, that is, based on the strength of the received signal, and then perform positioning calculations based on the corresponding data. This method can more accurately identify the location area of ​​the TAG device.

[0093] In one embodiment, the gate's entrance includes a first BLE Bluetooth device and its exit includes a second BLE Bluetooth device; therefore, obtaining the broadcast message sent by the TAG device in step S401 may include the following steps:

[0094] The broadcast message sent by the tag device is obtained based on the first BLE Bluetooth device and / or the second BLE Bluetooth device.

[0095] Understandably, BLE (Bluetooth Low Energy) devices can significantly reduce power consumption and cost while maintaining the same communication range as ordinary Bluetooth devices.

[0096] In this embodiment, BLE Bluetooth devices are installed at the entrance and exit of the turnstile. The BLE Bluetooth devices communicate based on the BLE Bluetooth channel. It can be understood that the entrance network in this embodiment includes both UWB and Bluetooth channels.

[0097] In this embodiment, BLE Bluetooth devices at the entrance and exit can scan TAG devices within Bluetooth communication range to obtain their broadcast messages. By initially filtering the RSSI of the TAG devices' Bluetooth broadcasts, basic location determination can be performed. Figure 1 In the A / B area, the initial determination is made through RSSI. If it is determined that the user has entered the A area, it means that the TAG device is near the entrance gate and the user may be about to enter the station. At this time, the UWB device uses the CH5 channel to communicate with the TAG device to complete the ranging and transaction.

[0098] Furthermore, in this embodiment, the addresses of the BLE Bluetooth devices corresponding to the entrance and exit gates respectively carry the identifier address of the entrance / exit network. After the TAG device establishes a connection with the BLE Bluetooth device, it can quickly identify whether the connection corresponds to an entrance gate or an exit gate based on the identifier address, and communicate with the UWB device using the corresponding UWB channel to complete ranging and transactions, thereby effectively improving ranging efficiency. Specifically, for the ranging method at the gate entrance, step S201, which performs a first ranging on the TAG device based on the first UWB channel, may include the following steps:

[0099] After the first BLE Bluetooth device establishes a link with the TAG device, the first BLE Bluetooth device at the entrance carries the first identification address of the entrance network, so that the TAG device can communicate using the first UWB channel corresponding to the entrance network based on the first identification address.

[0100] The ranging message of the TAG device is obtained based on the first UWB channel, and the first ranging is performed on the TAG device based on the ranging message.

[0101] Similarly, for the ranging method at the gate exit, the second ranging of the TAG device based on the second UWB channel in step S202 may include the following steps:

[0102] After the second BLE Bluetooth device establishes a link with the TAG device, the second BLE Bluetooth device carries the second identification address of the outbound network, so that the TAG device can communicate using the second UWB channel corresponding to the outbound network based on the second identification address.

[0103] In this embodiment, the ranging message of the TAG device is obtained based on the second UWB channel, and a second ranging is performed on the TAG device based on the ranging message. Whether the first BLE Bluetooth device and the second BLE Bluetooth device establish a link with the TAG device can be determined based on the identification result of the specific location area of ​​the TAG device. Specifically, during the first ranging or the second ranging process, the first BLE Bluetooth device links with the TAG device identified as being in the first location area, and the second BLE Bluetooth device links with the TAG device identified as being in the second location area.

[0104] In this embodiment, the first identifier address addr1 and the second identifier address adar2 can be fixed addresses, one of which represents the entry point and the other represents the exit point. In some embodiments, non-fixed addresses can also be used, that is, the first identifier address and the second identifier address have certain identifiable patterns to identify whether it is an entry point or an exit point.

[0105] Please refer to Figure 5 , Figure 5 This is a flowchart illustrating another UWB ranging method for gate entry and exit provided in this application embodiment. Based on the above embodiment, to further improve the accuracy of TAG device location identification, this embodiment pre-measures the distance and determines the location area of ​​the TAG device's travel direction before it enters area A / B, thus improving the accuracy of the TAG device's entry into area A / B. Specifically, in addition to steps S301 and S302 described above, the method provided in this embodiment also includes steps S501-S503.

[0106] Step S501: If the current location area of ​​the TAG device does not belong to the first location area and the second location area, then a third ranging is performed on the TAG device based on the first UWB channel or the second UWB channel.

[0107] Step S502: Based on the third ranging result, determine whether the driving direction of the TAG device is within the first location area. If the driving direction of the TAG device is within the first location area, perform a fourth ranging on the TAG device based on the first UWB channel to obtain the passage payment fee of the TAG device according to the fourth ranging result; or,

[0108] Step S503: Based on the third ranging result, determine whether the driving direction of the TAG device is in the second location area. If the driving direction of the TAG device is in the second location area, perform a fifth ranging on the TAG device based on the second UWB channel to obtain the passage payment fee of the TAG device according to the fifth ranging result.

[0109] In this embodiment, the third ranging method can be to randomly use either the first UWB channel or the second UWB channel to measure the distance to the TAG device.

[0110] In this embodiment, the driving direction of the TAG device is determined, that is, the displacement trend of the TAG device from its current position to its next position is determined, whether the displacement trend is moving towards the first position region or the second position region, or whether the displacement trend is moving closer to the first position region or the second position region, and then the corresponding UWB channel is used to measure the distance of the TAG device. For example, combined with Figure 1 As shown, the TAG device is in area C. The current TAG device may enter or leave the station. In this embodiment, the network can connect to it for both entry and exit and perform UWB ranging. The third ranging result provides feedback on whether its travel direction is closer to area A or area B. Compared with the above embodiment, the accuracy of entering area A / B is effectively increased by the pre-ranging ranging method, and the ranging efficiency is also effectively improved.

[0111] In another possible implementation, in addition to performing a fourth or fifth distance measurement in this embodiment, the first or second location area corresponding to the driving direction determined by the third distance measurement result can also be determined by the following method: randomly selecting a UWB channel or a second UWB channel to perform a third distance measurement on the TAG device. The distance measurement process may include continuously determining whether the TAG device has entered the first or second location area of ​​the gate entrance or exit. When it is determined that it has entered the first location area, the first distance measurement is performed on it using the first UWB channel and the payment fee is obtained. When it has entered the second location area, the second distance measurement is performed on it using the second UWB channel and the payment fee is obtained, so as to further increase the accuracy of the A / B area determination.

[0112] In summary, this embodiment effectively achieves automatic switching between CH5 and CH9 channels through BLE+UWB. Specifically, the RSSI signal strength indication information of the BLE Bluetooth device is used to identify the location area of ​​the TAG device, and the BLE Bluetooth address information or other information can be used to further assist the TAG device in distinguishing between the gate's entry and exit points, facilitating adaptive switching between CH5 and CH9 at the TAG end, and effectively improving the ranging and efficiency of UWB.

[0113] Please refer to Figure 6 , Figure 6This is a flowchart illustrating another UWB ranging method for gate entry and exit provided in this application embodiment. Based on the above embodiment, this embodiment aims to improve ranging speed and avoid problems such as inaccurate judgment by RSSI or other methods and lag caused by user movement. It determines whether the TAG device is entering or exiting the station by identifying the entry / exit status flag and performs ranging and transaction. Specifically, in addition to the above steps S301 and S302, the method also includes steps S601-S603.

[0114] Step S601: Determine whether the broadcast message sent by the TAG device carries an entry / exit status flag. The entry / exit status flag is generated by the TAG device based on the actual entry / exit situation or entry / exit requirements of the device. If the broadcast message of the TAG device carries an entry / exit status flag, then execute step S601; otherwise, execute step S301 or S302.

[0115] Step S602: Match the corresponding entrance / exit network based on the entrance / exit status flag; in this embodiment, the entrance network of the gate includes the first UWB channel, and the exit network of the gate includes the second UWB channel.

[0116] Step S603: Perform a sixth ranging on the TAG device according to the first UWB channel corresponding to the entrance network, and obtain the passage payment fee of the TAG device according to the sixth ranging result; or, Step S603': Perform a seventh ranging on the TAG device according to the second UWB channel corresponding to the exit network, and obtain the communication payment fee of the TAG device according to the seventh ranging result.

[0117] Specifically, for entry and exit TAG devices, their application status usually maintains the corresponding status. For example, applications such as Shenzhen Metro usually update their entry and exit status in the applet application, which can include the initial status, entry status, and exit status. If entry is successful, the latest status is the exit status. TAG devices can know the entry and exit status and can mark the current application's entry and exit status in broadcast messages.

[0118] In this embodiment, when a TAG broadcast message is detected, if the TAG device is in an entry state, it can be basically determined that the device is likely to enter the station next. Therefore, regardless of whether the TAG device is in area A, area B, or area C, the entry gate can prioritize connecting and waking it up for distance measurement. This method helps to improve the distance measurement speed, avoid lag caused by inaccurate RSSI judgment and user movement, and improve the judgment probability, further reducing the probability of false triggering of the gate when entering or leaving the station.

[0119] In a preferred embodiment, in conjunction with the content corresponding to the current location area of ​​the TAG device identified according to the signal strength indicator RSSI of the broadcast message in the above embodiments, step S601 can be performed before identifying the current location area of ​​the TAG device according to the signal strength indicator RSSI of the broadcast message. When it is determined that the broadcast message of the TAG device does not carry an entry / exit status flag, the current location area of ​​the TAG device is then identified according to the signal strength indicator RSSI of the broadcast message, thereby simplifying the ranging process. It should be noted that the ranging process described above in this embodiment, such as the fourth, fifth, and sixth ranging steps, can all be combined with the method of using the identification address of the BLE Bluetooth device mentioned in the above specification to complete the connection and ranging between the BLE device and the TAG device.
