The field level equipment mainly comprises: the system comprises an automatic ticket checking gate for entering, an automatic ticket gate for leaving, an automatic ticket machine, communication network equipment and a Bluetooth beacon. As shown in fig. 1, the front end server includes: a first memory (face image memory), a second memory (two-dimensional code memory), a third memory (face code memory), and a fourth memory (ticket checking result memory)
Fig. 2 shows a PRT new automatic ticketing method according to an exemplary embodiment of the present invention, including: judging whether the user selects a face ticket buying mode or not; if so, acquiring and caching the face image of the user to a first memory (a face image memory in a front server), and generating a first face code according to the face image of the user; sending a ticket request to a database server, wherein the database server responds to the ticket request and generates a face ticket form according to the first face code; if not, entering a two-dimensional code ticket purchasing mode of the automatic ticket vending machine to generate a two-dimensional code ticket, and storing the two-dimensional code ticket into a second memory (a two-dimensional code memory in a front server); wherein, the face ticket buying mode comprises the following steps: the face ticket purchasing method for the mobile account and the face ticket purchasing method for the automatic ticket vending machine.
Specifically, whether the user selects the face ticket purchasing mode of the mobile account is judged according to whether the passenger selects a mobile phone link or an applet pushed in the system. Firstly, a mobile phone with a Bluetooth function carried by a passenger and defaulted to start the Bluetooth function receives a Bluetooth beacon push mobile phone link or an applet in a waiting area, and the link or the applet prompts the passenger whether to agree to pay the ticket fee of the PRT system by using a third party face payment account of the passenger (such as a Payment treasure face payment account, but not limited to the face payment account). If the mobile phone of the passenger does not start the Bluetooth, the passenger can enter the same link or small program in a mobile phone code scanning mode before the face mobile payment billboard in the waiting area to make the passenger purchase the face ticket. Furthermore, after the passenger opens the link or the small program through the mobile phone, the system acquires the face ticket purchasing mode selected by the user through the mobile account, then further judging whether the user has a third party face payment account and whether the user agrees to use the existing third party face payment account to pay for the PRT system ticket fee (the ticket of the PRT system is made into a one-way ticket, the system can know that the passenger selects the face ticket purchasing mode of the mobile account, the PRT system ticket fee does not need to be charged by a program, the link or the small program of the mobile phone end can directly inform the passenger of the ticket price of the PRT traffic route), if so, the face image information of the user is obtained from the third party face payment account and cached to the first memory, reading user identity information in the third-party face payment account, and generating a first face code according to the read face image of the user; and sending a ticket request to a database server, wherein the database server responds to the ticket request and generates a face ticket form according to the first face code and the user identity information. If not, waiting for the user to register and bind the face payment account, and repeating the ticket buying process after the user performs face registration in third-party software of the mobile phone.
Fig. 3 shows an information transfer flow of a ticketing system in a mobile account face ticket buying mode according to an exemplary embodiment of the present invention, including:
s 101: and the interface server is communicated and interacted with the third-party face payment account and the interface server. After the third-party face payment account obtains a passenger authorization instruction, identity information (account name) on the account and passenger face image information corresponding to the account are transmitted into the PRT novel automatic fare collection system through the interface server. The account name of the passenger can be directly stored in the ticket information form of the database server through the preposed server. The passenger face image information corresponding to the account is firstly stored in a face image cache container (a first memory) of the front-end server.
s 102: the front server sends a face image and a face recognition analysis request to the face recognition server. The face recognition server acquires a face image, converts the face image into a 'face information code' (the first face information code in the ticketing stage) through a face recognition algorithm, and sends the 'face information code' and a ticketing request to the database server.
s 103: and the database server responds to the ticket request, receives the face information code and generates a face ticket form according to the first face code and the user identity information. In the process that the database server responds to the ticket request, overtime response judgment is further set to avoid inconvenience brought to passengers due to the fact that the network is not smooth, whether the database server responds to the ticket request within preset time (generally within 30 s) or not is judged, the face ticket business form is generated, if yes, prompt information of ticket purchasing success is sent to a third-party face payment account, and if not, face images of the users cached in the first storage are removed.
Further, if the user selects the face ticket buying mode of the automatic ticket vending machine, the automatic ticket vending machine responds to the face ticket buying request of the user, and the method comprises the following steps: acquiring a face image of a user, judging whether the acquired face image of the user meets the quality requirement, if not, quitting the face ticket purchasing mode of the ticket vending machine, and entering a two-dimensional code ticket purchasing mode of the ticket vending machine; if yes, caching the face image of the user to a first storage, and sending a payment packaging request to the ticket vending machine; and analyzing the payment result returned by the ticket vending machine.
Specifically, fig. 4 shows an information transfer flow of a ticketing system in a mode of buying a ticket by using a face ticket of an automatic ticketing machine according to an exemplary embodiment of the present invention, where the information transfer flow includes:
and s201, activating the ticket vending machine from a standby state to a ticket purchasing interaction state, and requesting face acquisition authorization to passengers. And after the authorization of the passenger is obtained, starting a face acquisition function to perform automatic snapshot, and completing face image acquisition. And if the quality of the photo meets the quality requirement of the facial feature image, reminding the passenger of selecting a payment mode and sending a ticket buying transaction request to the front-end server. (as a standby ticketing mode, if a passenger refuses a face acquisition request, the mode is automatically switched to a two-dimensional code paper ticketing mode, and a printing drive is started at the same time.)
And s202, after the front-end server determines that the transaction type is a face ticket purchasing mode, encrypting and caching the passenger face image in a face image caching container, and sending a payment group package request to the interface server. The interface server firstly judges the payment type, such as WeChat payment, Payment treasure payment and the like, then acquires corresponding external payment interface parameters, sends a payment request to an external payment interface, finally acquires a payment result and simultaneously responds the payment result to the front-end server after receiving the payment group package request. If the response of the step is overtime, the abnormal overtime is reminded.
And s203, the front-end server judges the payment result, and sends a face picture and a face recognition request to the face recognition server after a signal of successful payment is obtained. If the payment process is overtime or the payment fails, the front-end server clears the cached face picture and sends the payment result to the ticket vending machine to remind passengers of ticket buying failure; the face recognition server generates a face information code from the face picture, and then sends the face information code and a ticket service request to the database server.
And s204, after receiving the ticket request signal, the database server firstly stores the face information code, then analyzes the ticket request, records and stores the ticket transaction record, generates ticket information, binds the face information code and the ticket information (such as order number, order amount, ticket number, ticket drawing time and the like), generates a ticket information form, and sends a response request to the front-end server. And (if the two-dimensional code is in a two-dimensional code paper ticketing mode, binding the two-dimensional code with the ticket information to generate a ticket information form), and further, judging whether the response of the response database server is overtime by the front-end server. And if not, acquiring the ticket order. If the front server judges that the response is overtime, the front server initiates a refund request to the interface server. After the interface server receives the refund request, the payment type is judged firstly, then corresponding external refund interface parameters are obtained, the refund request is sent to an external refund interface, finally, a refund result is obtained, meanwhile, the refund result is responded to the front-end server, and if the process is overtime, abnormal recording is carried out. And the front-end server clears all caches related to the steps of the process, including the face images in the face image cache container of the front-end server, protects the privacy of passengers, and sends ticket buying result responses to the ticket checking machine of the station entry. And s205, the automatic ticket vending machine displays that the face ticket purchasing payment is successful, a face ticket is generated, and the passenger can take the face as a ticket carrier and go to the ticket checking gate for ticket checking and taking a bus.
In the ticket selling process, if a passenger (user) selects a two-dimensional code ticket selling mode of the automatic ticket selling machine, the system central equipment server sends a payment group packaging request to the automatic ticket selling machine and waits for the automatic ticket selling machine to return a payment result; analyzing a payment result returned by the ticket vending machine, judging whether the user successfully responds to the payment packaging request according to the payment result, if so, analyzing the payment result to obtain payment information of the user, generating a two-dimensional code ticket according to the payment information, storing the two-dimensional code ticket information into a second memory, and driving and printing a two-dimensional code paper ticket; and if not, sending prompt information of payment failure to the ticket vending machine.

In a further embodiment of the present invention, as shown in fig. 5 and 6, there is also provided a PRT novel automatic ticket checking method, including:
responding to a face ticket checking request of a user, acquiring a face image of the user and caching the face image of the user to a first memory; generating a second face code according to the currently acquired face image, and caching the second face code into a third memory; sending a face code query request to a database server, traversing a face ticket ticketing form in the face code query request by the database server in response to the face code query request, judging whether face code information matched with a second face code in the third memory exists in the face ticket ticketing form, obtaining a ticket checking result, and caching the ticket checking result into a fourth memory; analyzing the ticket checking result in the fourth memory, and starting or closing a gate according to the ticket checking result; or responding to a two-dimensional code ticket checking request of a user, reading the two-dimensional code ticket information from a second memory for storing the two-dimensional code ticket information for verification, and starting or closing the gate according to the verification result.
When passengers directly walk to the automatic ticket checking gate for entering the station, the ticket checking gate for entering the station starts a face acquisition program, and a camera module of the ticket checking gate for entering the station enters a normally open state to capture face images entering a focal range in real time. And automatically capturing the picture meeting the quality requirement of the face characteristic image to finish face image acquisition. And analyzing the quality of the acquired face image, if the quality of the face image meets the requirement, comparing the face, and judging whether the face electronic ticket is effective. And if the quality of the face image does not meet the requirement, prompting the passenger to acquire the face image again. And if the face comparison result shows that the face ticket is a valid face ticket, the automatic ticket checking gate machine opens the gate and releases the gate. And if the ticket is an invalid face ticket, prompting the passenger to check the two-dimensional code paper ticket. And when the two-dimensional code paper ticket is verified to be effective, the ticket checking gate machine enters the station and is opened for releasing. And when the two-dimensional code paper ticket is verified to be invalid, returning to the face acquisition step, and checking the ticket again. When passengers are out of the station, the gate machine in the PRT system automatically opens the gate in an infrared detection mode and releases the gate.
Specifically, adopt the face to remove the payment mode and carry out automatic ticket checking in-process ticket checking system information transfer flow, include:
and s301, the passenger directly walks to the automatic ticket checking gate of the station.

And s302, caching the 'analysis ticket checking request' by the front-end server, caching the acquired face image into a front-end server face image caching container, and sending a face image and face comparison request to the face recognition server. The face recognition server obtains a face image, converts the face image into a face information code through a face recognition algorithm, and caches the face information code to a face information code cache container of the front-end server. The front-end server acquires the face information code of the current passenger entering the station and sends a face information code effective query request to the database server.
And s303, the database server responds to the effective query request of the face information code, reads the face information code which needs to be verified currently in the face information code cache container in the front server, and searches the face information code in the passenger ticketing information form of the database to judge the effectiveness of the current face information code in a query comparison mode. If the current 'face information code' needing to be verified is successfully compared with the 'face information code' in the database, namely the current 'face information code' needing to be verified is an effective code, ticket business information related to the 'face information code' is extracted from the database, and an 'analysis ticket checking request' is responded to the front-end server. If the comparison between the face information code which needs to be verified at present and the face information code in the database is invalid, namely the face information code which needs to be verified at present is an invalid code, sending an analysis ticket checking request corresponding to the invalid code to the front-end server.
And s304, the front-end server analyzes the ticket checking request, acquires the valid/invalid information of the face information code, the ticket information related to the face information code, the ticket gate number of the ticket gate entering the station and the like, and caches the ticket checking result containing the information into a ticket checking result cache container. And traversing all ticket checking results in the ticket checking result cache container by the front-end server, sending a gate opening or ticket checking failure instruction to the current station-entering ticket checking gate waiting for ticket checking according to the traversal result, and responding to the ticket checking result.
And s305, after the passenger who adopts face payment enters the station checking ticket machine to open the gate, the current gate sends a fee deduction request to the front server. The front server responds to the fee deduction request, reads the ticket information related to the face information code corresponding to the current passing gate passenger, and initiates the fee deduction request with a third-party face payment account through the interface server by adopting the account name in the ticket information. And the third-party face payment account completes the riding payment of the current passenger after receiving and verifying the fee deduction request, and sends a fee deduction request response to the front-end server through the interface server. After the fee deduction is finished, the front-end server deletes the face information codes in the face information code cache container and sends a ticket state updating request to the database server.
And s306, the database server responds to the ticket state updating request, executes a ticket failure instruction, and performs ticket failure processing on the ticket information bound with the original face information code in the database server. And sends a "response request" to the front-end server. The front-end server clears all caches related to the steps of the process, including the face images in the face image cache container of the front-end server, so that privacy of passengers is protected.
Further, fig. 7 shows an information transfer flow of a ticket checking system in an automatic ticket checking process by using a face ticket purchasing method of an automatic ticket vending machine according to an exemplary embodiment of the present invention, where the information transfer flow includes:
step 401, after the automatic ticket checker entering the station starts, the camera module enters a normally open state, captures a face image entering a focal range in real time, automatically captures a picture meeting the quality requirement of a face characteristic image, finishes face image acquisition, and sends an analysis ticket checking request to a front-end server. (if the passenger holds the two-dimension code ticket, the gate two-dimension code collector finishes the two-dimension code collection)
And step 402, the front-end server caches and analyzes the ticket checking request, caches the acquired face image to a front-end server face image caching container, and sends a face comparison request to the face recognition server. The face recognition server obtains a face image (the collected two-dimensional code is cached in a two-dimensional code caching container), converts the face image into a face information code through a face recognition algorithm, and then sends the face information code to the front server. The front server acquires the face information code and stores the face information code in a face information code cache container, and sends a 'face information code effective query request' to the database server.
In step 403, the database server responds to the "face information encoding valid query request". Reading the face information code which needs to be verified currently in a face information code cache container in the front-end server, simultaneously reading a face information code library cached in a ticketing stage, and judging the validity of the current face information code in a query comparison mode. After finishing face information coding and associated ticket information query, the database server initiates a ticket information analysis request to the preposed server. If the current face information code is an effective face information code, ticket information related to the face information code is extracted from a database, and a ticket information analysis request is sent to the front-end server. If the current face information code is an invalid face information code, the face information code is an invalid ticket checking result, and a ticket analysis information request is sent to the front-end server.
And step 404, the front-end server analyzes the ticket information, acquires the information of the ticket validity, the riding time period, the riding starting station and the like, and caches the ticket checking result containing the information into a ticket checking result cache container. And traversing all ticket checking results in the ticket checking result cache container by the front-end server, sending a gating or ticket checking failure instruction to the current station-entering ticket checking machine waiting for ticket checking according to the traversal result, and responding to the ticket checking result. If the front-end server traverses all ticket checking results and is not successfully matched with the current face information code, or the response of the ticket checking request is overtime, a ticket checking failure instruction is sent to the current automatic ticket checking machine waiting for ticket checking. And after the ticket checking machine of the incoming station is opened, sending an analysis request to the front-end server.
Step 405, the front-end server responds to the analysis request after the gate is opened, and sends a ticket state updating request to the database server. The database server responds to the ticket state updating request, executes a ticket failure instruction, performs ticket failure processing on ticket information bound by the original face information code in the database server, and sends a response request to the front-end server. The front-end server clears all caches related to the steps of the process, including the face images in the face image cache container of the front-end server, so that privacy of passengers is protected.
In this embodiment, after the gate is opened for releasing, the front-end server clears all the cached information of the user in the first memory, the third memory and the fourth memory (if the two-dimensional code is the two-dimensional code, the cached information in the second memory is cleared), and the database server marks the face ticket form of the user as a failure ticket, so that the privacy of passengers can be effectively protected, the data weight of the front-end server, especially the light weight of the face image data, can be effectively realized, and meanwhile, the user can print the corresponding ticket after the bus is finished by reserving the ticket form in the database server, thereby avoiding the defect that the face ticket cannot print the reimbursement basis.
Example 3
In a further embodiment of the present invention, as shown in fig. 8 to 10, the inbound automatic ticket gate includes: the ticket checking system comprises a ticket checking gate body 1 and a control module arranged in the ticket checking gate body 1, wherein the ticket checking system is arranged at an entrance ticket checking port; the ticket checking system also comprises a face acquisition module 2 and a two-dimensional code scanning module 3 which are arranged on the ticket checking gate body 1, and the two-dimensional code scanning module 3 is arranged in front of the face acquisition module 2; the gate mechanism 4 is arranged on one side of the ticket checking gate body 1, and the network interface module is arranged in the ticket checking gate body 1; wherein, the face collecting module 2 comprises: a camera 21 and a display screen 22.
Two modes of interval arrangement are designed for the face acquisition module 2 and the two-dimensional code scanning module 3 of the ticket checking gate machine entering the station. Firstly, sweep code module 3 with the two-dimensional code with the interval of people's face collection module 2 sets up to be greater than camera 21's collection scope. As shown in fig. 9, taking the focal length of the face capturing camera as 1m (the capturing range is 1m, and the face capturing is started only after a person enters the capturing range of the camera) as an example, the distance d between the face capturing camera and the face capturing camera is 1.2m, and the focal length greater than the focal length of the face capturing camera is 1 m. At the moment, if the passenger holds the two-dimensional code ticket by hand, the passenger should be parked in the two-dimensional code scanning area, the passenger can wait for the server to compare the received two-dimensional code ticket information with the pre-stored two-dimensional code ticket information (information stored in the ticket purchasing stage), and if the comparison is successful, an opening signal is sent to the gate mechanism to release the passenger. If the passenger does not check the ticket in the two-dimensional code scanning area, the passenger directly enters the face collecting area, after the face of the passenger is collected by the camera, the server compares the received face image with the pre-stored face image, and the server fails in the face image comparison due to the fact that the passenger purchases the two-dimensional code ticket, and then sends text prompt information to the display 22 through the control module to remind the passenger of' failure in face ticket checking, please check the ticket with the two-dimensional code, and the passenger waits for returning to the two-dimensional code collecting area to complete two-dimensional code ticket checking. If the passenger purchases the face ticket, when the passenger can directly enter the acquisition range of the camera to check the face image, the server receives the face image from the control module, and makes comparison, and after the ticket check is successful, the server can prompt that the ticket check is successful and the passenger passes through by characters. For passengers with privacy concerns, the ticket checking system which collects face images after giving priority to the two-dimensional codes enables the passengers to check tickets and pass through the two-dimensional codes without stepping into a collecting area of a camera to collect the face images, and the privacy of the passengers can be effectively protected; meanwhile, by adopting the layout mode, the server only needs to perform data processing in two-dimensional code ticket information comparison or human face image comparison, so that the calculation amount of the server can be reduced, and the processing efficiency is further improved. Secondly, the distance between the two-dimension code scanning module 3 and the face collecting area 2 is set to be smaller than the collecting range of the camera 21, as shown in fig. 10, the distance L between the two is 0.4m, which is smaller than the collecting range of the face collecting camera 1 m. In this way, the range of the face collection area covers the range of the two-dimensional code scanning area, so that no matter a passenger purchases a face ticket or a two-dimensional code ticket, the ticket checking gate can default to the face ticket, carry out face collection and then check the ticket, and if the face ticket is effective, the gate is opened for releasing; and if the face ticket is invalid, reminding the passenger to check the ticket by the two-dimensional code. During the face collection and face ticket checking, if a passenger places a two-dimensional code ticket in a two-dimensional code scanning area, the ticket checking gate interrupts the face ticket checking process, clears all the cache memories, performs two-dimensional code ticket checking, and passes if the two-dimensional code ticket checking is valid.
