[0045] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0046] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0047] Reference Figure 1 , shows a schematic diagram of the structure of a control system of an automatic ticket vending and checking gate provided in an embodiment of the present application, such as Figure 1 As shown, the control system 100 of the automatic ticket vending and checking gate may include: N UWB base stations 101 , a server 102 , an electronic voucher body 103 with UWB function, and M gates 104 .

[0048] The N UWB base stations 101 may be communicatively connected with the electronic certificate entity 103 that enters the monitoring area of ​​the N UWB base stations to perform information exchange with the electronic certificate entity 103 .

[0049] The server 102 can be respectively connected to communicate with N UWB base stations 101 and M gates 104 to receive the interaction information between the N UWB base stations 101 and the electronic certificate body 103, locate the electronic certificate body 103, and determine the target gate that communicates with the electronic certificate body 103 among the M gates 104 according to the positioning information. The account information of the electronic certificate body 103 is sent to the target gate, so that the target gate performs authentication, authorization and billing processing on the electronic certificate body 103 according to the account information, and opens the gate of the target gate after the billing is completed, so that the user holding the electronic certificate body 103 can pass through the gate.

[0050] In this embodiment, UWB (Ultra Wide Band) technology is a new type of wireless communication technology, which is very different from traditional communication technology. It transmits data and serves as a positioning carrier by sending and receiving extremely narrow pulses with nanosecond or even sub-nanosecond levels. It has low wireless power density and strong anti-interference ability.

[0051] The monitoring area of ​​the UWB base station, that is, its coverage range, UWB technology uses a large range of spectrum to transmit short wireless pulses. The characteristics of these pulses (such as time, frequency and phase, etc.) can achieve precise positioning of the electronic certificate body.

[0052] In a specific implementation, the server 102 may pre-divide the gate into an initialization area, a tracking and locating area, and an authorization and billing area, that is, according to the layout of the gate, the surrounding area is designed as: an initialization area, a positioning and locating area, and an authorization and billing area.

[0053] When a user enters the "initialization area" with an electronic certificate with UWB function, the server can communicate and locate the electronic certificate through the UWB base station, and determine whether the electronic certificate is legitimate. Specifically, the server can pre-store the certificate identifier of the pre-registered electronic certificate (used to indicate the unique identity of the electronic certificate), and can determine whether the electronic certificate is legitimate through the identifier of the electronic certificate.

[0054] When the user enters the location tracking area, the server can continuously track the real-time location of the legal electronic certificate body and prepare for the next step of entering the authorized billing area. The location process of the electronic certificate body will be described in detail in the following embodiments, and will not be repeated in this embodiment.

[0055] When a user enters the authorized billing area, the gate to be used by the electronic certificate entity can be determined through the multi-gate contention algorithm, and the gate can be marked as occupied. At this time, the gate will not provide services to other users. The electronic certificate entity can perform two-way authentication, authorization and billing with the gate. The gate will display the authorized electronic certificate information and allow it to pass. Otherwise, the gate will prompt an alarm and close the gate to prohibit it from passing. When leaving the "authorized billing area", the gate will mark the electronic certificate for billing and close the communication between the gate and the electronic certificate.

[0056] In a specific implementation of the present application, each gate may include: an MCU (Microcontroller Unit), a display, and a door module, wherein the MCU may be used to authenticate, authorize, and process the account information of the electronic credential. The display may be used to display the authorized electronic credential information. The door module may be used to control the opening and closing of the gate.

[0057] In another specific implementation of the present application, N is a positive integer greater than or equal to 4. By setting 4 or more UWB base stations, the accuracy of positioning the electronic certificate body can be improved. The implementation process of locating the real-time position of the electronic certificate body by 4 UWB base stations will be described in detail in the following embodiments, and this embodiment will not be repeated here.

[0058] In another specific implementation of the present application, the electronic certificate body can be any of the bodies such as an electronic card, a mobile device (such as a mobile phone, etc.), and a car key. The embodiment of the present application can have a UWB function built into a variety of bodies to realize automatic authentication, authorization, and billing of automatic ticket vending and checking gates. It can solve the problem of actively identifying, authenticating, and authorizing passengers' electronic certificates and controlling the gate switch without requiring specific actions when the passengers approach the ticket checking area without the passengers being aware of it, while being easy for users to carry and improving the user experience.

[0059] The control system of the automatic ticket vending and checking gate provided in the embodiment of the present application includes: N UWB base stations, a server, an electronic voucher body with UWB function and M gates, where M and N are both positive integers, wherein the N UWB base stations are connected in communication with the electronic voucher body within the monitoring area of ​​the N UWB base stations to exchange information with the electronic voucher body. The server is connected in communication with the N UWB base stations and the M gates respectively, receives the interaction information between the N UWB base stations and the electronic voucher body, locates the electronic voucher body, determines the target gate that communicates with the electronic voucher body among the M gates according to the positioning information, and sends the account information of the electronic voucher body to the target gate, so that the target gate authenticates, authorizes and processes the electronic voucher body according to the account information, and opens the gate of the target gate after the billing is completed. The embodiment of the present application uses the interaction between the UWB base station and the electronic voucher body to locate the electronic voucher body in real time, so as to establish a secure payment data link with the electronic voucher according to the distance between the electronic voucher body and the gate, and to authenticate the electronic voucher billing. If the authentication is passed, the door will be opened and the passenger with the electronic voucher will be allowed to pass through the gate. In this process, there is no need for passengers to perform specific actions (such as swiping cards, face recognition, etc.), and information verification can be automatically performed and the gate can be opened without the passengers noticing, which improves the passenger experience and the passing efficiency of the gate.

[0060] Reference Figure 2 , shows a flow chart of the steps of a control method of an automatic ticket vending and checking gate provided by an embodiment of the present application, such as Figure 2 As shown, the control method of the automatic ticket vending and checking gate may include: step 201, step 202, step 203 and step 204.

[0061] Step 201: calling a server to obtain interaction information between an electronic certificate body with UWB function and N UWB base stations when the electronic certificate body enters the monitoring area of ​​N UWB base stations, where N is a positive integer greater than or equal to 1.

[0062] The embodiments of the present application can be applied to the control system of the automatic ticket vending and checking gate provided in the above embodiments. Figure 3As shown, the control system may include: N UWB base stations, a server, an electronic certificate body with UWB function and M gates, where M and N are both positive integers. Figure 3 The dashed line indicates a wireless connection, and the dashed line indicates a wired connection. Figure 3 As shown, the UWB electronic certificate (i.e. the electronic certificate body in this example) can be wirelessly connected to the UWB base station, the UWB base station can be wired connected to the communication and positioning service (i.e. the server in this example), and the communication and positioning server can be wired connected to the gate.

[0063] When the electronic certificate body with UWB function enters the monitoring area of ​​N UWB base stations, the server can be called to obtain the interactive information between the electronic certificate body with UWB function and the N UWB base stations in the monitoring area of ​​the N UWB base stations, where N is a positive integer greater than 1. Specifically, when the electronic certificate body enters the initialization area of ​​M gates, the server is called to obtain the certificate identification information of the electronic certificate body based on the N UWB base stations. Based on the certificate identification information, the legitimacy of the electronic certificate body is verified, and after the electronic certificate body is verified, the interactive information between the electronic certificate body and the N UWB base stations is obtained.

[0064] In a specific implementation, the server may pre-design the surrounding area of ​​the gate according to its location into: an initialization area, a positioning and tracking area, and an authorization and billing area.

[0065] When the electronic certificate enters the initialization area of ​​M gates, the server can verify the legitimacy of the electronic certificate based on the identification of the electronic certificate. If the verification is successful, the interaction information between the electronic certificate and N UWB base stations can be obtained. Specifically, when a passenger enters the "initialization area" with a UWB electronic certificate, the communication and positioning service activates the communication with the UWB electronic certificate through the UWB base station and verifies the legitimacy of the electronic certificate. Figure 7 As shown, when a user holds an electronic certificate with UWB function and enters the initialization area, he can communicate with four UWB base stations, and the interactive information between the four UWB base stations and the electronic certificate can realize the positioning of the electronic certificate.

[0066] In this example, the interactive information between the UWB base station and the electronic certificate entity can be: after the electronic certificate entity enters the base station monitoring area, all UWB base stations send POLL information (i.e., polling trigger message) to the electronic certificate entity. After the electronic certificate entity obtains the POLL information based on the message arrival time difference, it will feedback RESP information (i.e., response message, including timestamp) after processing. After all base stations receive the RESP feedback from the electronic certificate entity, they can send FINAL information (including timestamp) to the electronic certificate entity. The information sent between the electronic certificate entity and all UWB base stations is the interactive information.

[0067] After the calling server obtains the interaction information between the electronic voucher body with UWB function and the N UWB base stations after entering the monitoring area of ​​the N UWB base stations, step 202 is executed.

[0068] Step 202: Determine the real-time location information of the electronic certificate body according to the interaction information.

[0069] After obtaining the interaction information between the electronic credential body with UWB function and N UWB base stations, the real-time location information of the electronic credential body can be determined according to the interaction information, that is, the electronic credential body can be located in real time according to the interaction information. Specifically, when the electronic credential body enters the real-time tracking area of ​​M gates, the interaction information containing the timestamp of the electronic credential body and the N UWB base stations can be obtained. And the arrival time difference algorithm is used to calculate the real-time location information of the electronic credential body according to the timestamp in the interaction information, the base station location information of the N UWB base stations, and the time difference information of the interaction information arriving at the N UWB base stations.

[0070] In this example, when the arrival time difference algorithm is used to locate the electronic certificate body, the number of UWB base stations is at least four. When the UWB base stations are arranged at fixed positions, the positions of 4 base stations can be configured in the server, and the base stations are time synchronized based on wired communication. If the electronic certificate (Tag) with UWB function enters the initialization area, the electronic certificate sends broadcast information to each base station, and the communication and positioning service uses the arrival time difference method (TDOA) to calculate the specific location of the electronic certificate. Specifically, all base stations send the time difference information between each base station and the electronic certificate body to the communication and positioning service. The communication and positioning service uses this time difference information and combines it with the wireless transmission speed (which can be the speed of light in this embodiment), and then uses a specific nonlinear equation group optimization method (such as the classic Chan algorithm, Taylor algorithm) to obtain the accurate position (x t ,y t ). The calculation formula for the positioning position of the electronic certificate body is as follows:

[0071]

[0072] In the above formula, c is the speed of light, Δt ij is the time difference between the signal of the electronic voucher body reaching base station i and base station j, i,j=1,2,3,4.

[0073] For the arrival time difference, it can be combined Figure 4 The following description is given.

[0074] Figure 4A schematic diagram of signal logic between an electronic certificate and a base station provided in an embodiment of the present application is shown, Figure 4 As shown, taking the interaction between base station 1 and electronic voucher as an example, base station 1 at time t 11 Send POLL to the electronic certificate, the electronic certificate at time t 21 Receive POLL, then the electronic certificate is issued at time t 22 Send RESP to base station 1, which sends RESP to base station 1 at time t 12 After receiving RESP, finally, base station 1 at time t 13 Send FINAL, electronic certificate at time t 23 Receive FINAL. Then the communication and positioning service calculates Δt1 between base station 1 and the electronic certificate as formula (1), and the electronic certificate calculates Δt1 as formula (2).

[0075] Δt1=[(t 12 -t 11 )+(t 22 -t 21 )] / twenty one)

[0076] Δt1=[(t 13 -t 12 )+(t 23 -t 22 )] / twenty two)

[0077] It can be understood that the above formula (1) is the signal time difference between the base station 1 and the electronic certificate calculated by the communication and positioning service. The above formula (2) is the signal time difference between the base station 1 and the electronic certificate calculated by the electronic certificate. When calculating the real-time location of the electronic certificate, the signal time difference calculated by the communication and positioning service can be used as the basis for calculation.

[0078] Of course, in a specific implementation, other methods can also be used to locate the real-time position of the electronic certificate. For example, taking two UWB base stations as an example, information can be sent to the electronic certificate through these two base stations to obtain the information transmission time between the base station and the electronic certificate. The distance between the two base stations and the electronic certificate can be calculated by the information transmission time and the speed of light. Then, combining the positions of the two base stations and the two calculated distances, a triangle is constructed with the positions of the two base stations and the position of the electronic certificate, so as to calculate the real-time position of the electronic certificate. It can be understood that the positioning method for the real-time position of the electronic certificate can be determined according to business needs, and this embodiment does not limit this.

[0079] After the real-time location information of the electronic voucher body is determined according to the interaction information, step 203 is executed.

[0080] Step 203: When the real-time location information indicates that the electronic certificate entity is within the authorized billing area of ​​M gates, determine the target gate for communicating with the electronic certificate entity among the M gates based on the real-time location information, where M is a positive integer greater than 1.

[0081] When the real-time location information indicates that the electronic voucher is in the authorized billing area of ​​M gates, the target gate that communicates with the electronic voucher can be determined based on the real-time location information of the electronic voucher. The target gate can be used as the gate for authenticating, authorizing and billing the electronic voucher. Figure 8 As shown, the information interacted with the UWB electronic voucher by the four base stations can locate the user's location information in real time, so as to select a gate according to the user's real-time location information, that is, to select a target gate from multiple gates. It can be understood that the gate selection area can be a positioning tracking area, or a part of the positioning tracking area close to the authorized billing area, etc., which is not limited in this embodiment.

[0082] In a specific implementation of the present application, the distance between the electronic certificate body and the M gates can be determined based on the real-time location information of the electronic certificate body and the gate location information of the M gates, and the gate closest to the electronic certificate body can be selected from the M gates as the target gate. Figure 5 As shown, the UWB electronic certificate is closest to gate A among gate A, gate B and gate C. At this time, gate A can be used as the target gate.

[0083] In another specific implementation of the present application, the distance between the electronic certificate body and the M gates can be determined based on the real-time location information of the electronic certificate body and the gate location information of the M gates. When the distance between the electronic certificate body and the first gate and the second gate among the M gates indicates that the distance is the same, the horizontal clockwise angle between the electronic certificate body and the first gate and the second gate is calculated. The gate with the smallest horizontal clockwise angle is selected from the first gate and the second gate as the target gate. Figure 6 As shown, the horizontal clockwise angle between the UWB electronic certificate and gate C is 11, the horizontal clockwise angle between the UWB electronic certificate and gate B is 12, and the horizontal clockwise angle between the UWB electronic certificate and gate A is 13. The distance between the UWB electronic certificate and gates A and B is the same. At this time, the horizontal clockwise angle between the UWB electronic certificate and gate A is the smallest, so gate A can be used as the target gate.

[0084] The embodiment of the present application is directed to a control system for multiple gates, and adopts the principle of "distance first, direction second", so that gates that meet user needs can be screened out for binding communication.

[0085] After the target gate is determined, the state of the target gate can be marked as occupied. At this time, other electronic certificates cannot use the gate, that is, the target gate no longer provides services to other users until the gate and the electronic certificate body complete the authentication, authorization and billing tasks.

[0086] After the target gate communicating with the electronic voucher body among the M gates is determined based on the real-time location information, step 204 is executed.

[0087] Step 204: Send the credential account information corresponding to the electronic credential body to the target gate so that the target gate can authenticate, authorize and bill the credential account information, and after successful processing, start the gate of the target gate to allow the user holding the electronic credential body to enter.

[0088] After determining the target gate that communicates with the electronic certificate body among the M gates based on the real-time location information, the credential account information corresponding to the electronic certificate body can be sent to the target gate, so that the target gate can authenticate, authorize and bill the credential account information, and after the processing is successful, the gate of the target gate is started to allow the user holding the electronic certificate body to enter. Specifically, when the electronic certificate body is in the authorized billing area, the server can send authorization and billing messages to the electronic certificate body, and the electronic certificate body can send its credential account information to the server, so that the server can send it to the target gate. An MCU (such as a MCU) is set in the gate. Figure 3 As shown in the figure, the MCU can decrypt the credential account information, as well as perform authentication, authorization and billing. If the above operations are successful, the electronic credential information can be displayed on the display of the target gate and the passer-by can be allowed to pass. Otherwise, the target gate will give an alarm and close the gate to prevent the passer-by from passing.

[0089] It can be understood that in the communication process between the electronic certificate body and the gate machine, the interactive information can be encrypted using an algorithm such as the SM2 algorithm to improve the security of the interactive information.

[0090] When the target gate machine and the electronic certificate complete authentication, authorization, and billing, the server can mark the state of the target gate machine as unoccupied, so that other users can use it normally.

[0091] The control method of the automatic ticket vending and checking gate provided in the embodiment of the present application calls a server to obtain the interactive information between the electronic voucher body with UWB function and N UWB base stations in the monitoring area of ​​N UWB base stations, where N is a positive integer greater than or equal to 1. According to the interactive information, the real-time location information of the electronic voucher body is determined. In the case where the real-time location information indicates that the electronic voucher body is in the authorized billing area of ​​M gates, the target gate that communicates with the electronic voucher body among the M gates is determined based on the real-time location information, where M is a positive integer greater than 1. The voucher account information corresponding to the electronic voucher body is sent to the target gate, so that the target gate authenticates, authorizes and bills the voucher account information, and after the processing is successful, the gate of the target gate is started to allow the user holding the electronic voucher body to enter. The embodiment of the present application performs real-time positioning of the electronic voucher body through the interaction between the UWB base station and the electronic voucher body, so as to establish a secure payment data link with the electronic voucher according to the distance between the electronic voucher body and the gate, and to authenticate the electronic voucher billing. If the authorization authentication is passed, the door is opened and the passenger holding the electronic voucher is allowed to pass through the gate. During this process, passengers do not need to perform specific actions (such as swiping cards, facial recognition, etc.). Information verification can be automatically performed and the gate can be opened without the passengers noticing, which improves the passenger experience and the efficiency of the gate.

[0092] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
