[0056] The second reader / writer 32 is connected to the third QR code scanner 33 and is used to read the QR code information of the paper QR code one-way ticket;

[0057] The controller 31 is connected to the second reader / writer 32 and is used to interact with the online platform 6 to verify the ticket information.

[0058] The online authenticated rail transit paper two-dimensional code one-way ticket application system provided by the present invention is an automated system based on computer technology, network technology, automatic control technology, etc., which can realize the whole process of ticket purchase, printing, billing, charging and statistics.

[0059] The clearing system 7 can be realized by a computer, can record the fund transactions, summarize and classify them according to certain rules to calculate the statement file, and perform the netting process. The online platform 6 is used to generate QR code data and verify the validity of the paper QR code single-trip ticket.

[0060] The automatic ticket vending machine device 1 is installed at each rail transit line station, and sells and prints paper QR code tickets by communicating with the online platform 6.

[0061] The semi-automatic ticket vending machine 2 is installed at each rail transit line station, and sells paper QR code tickets and performs status analysis through communication with the online platform 6.

[0062] The second reader / writer 32 and the third QR code scanner 33 of the gate machine 3 read the QR code information in the paper QR code one-way ticket, and communicate with the online platform 6 to verify the validity of the ticket and determine the pass authorization.

[0063] The first QR code scanner 11 is also used to scan and identify the paper QR code single-trip ticket printed by the ticketing device or the QR code displayed by the terminal device APP. The first printer module 12 is used to print the QR code and corresponding text on the blank paper ticket. The ticket management module 13 is used to manage the unprinted paper tickets in the terminal device.

[0064] The working principle of the rail transit paper QR code one-way ticket application system for online authentication of this embodiment is further introduced below:

[0065] When the online platform 6 receives the request sent by the terminal device, it performs the code sending operation according to the received order number, node identification code, fare and other information, combines the validity period of the QR code, account number, etc., and calculates the verification code through the key algorithm to generate a QR code. Preferably, the QR code is encoded in QR Code and represented by binary (non-ASCII code) invisible characters.

[0066] The generated QR code string is then sent to the terminal device to generate a QR code. Data authentication and access control are achieved accordingly. The security authentication information is the security authentication data that authenticates the relevant data through the process key and the security encryption algorithm.

[0067] The automatic ticket vending machine 1 generates a paper single-trip ticket based on the received QR code. Specifically, the automatic ticket vending machine 1 prints the QR code information on a new paper ticket based on the received QR code information and in combination with the first printer module 12 and the ticket management module 13 in the device, and spits out the ticket. The terminal device uploads the ticket sales result message to the clearing subsystem 7.

[0068] The terminal device serves as the printing carrier of the QR code, and the paper QR code serves as the ticket of the rail transit ticket sales and consumption system.

[0069] In a preferred embodiment, the second reader / writer 32 includes a key module, which includes a plurality of terminal security control module cards, and the terminal security control module cards store process keys and programs for data encryption or decryption; the second reader / writer 32 is a reader / writer compatible with multiple types of rail transit tickets.

[0070] Specifically, when entering the station, the user aligns the QR code on the ticket with the scanning area of ​​the gate 3, and the second reader 32 reads the QR code information through the third QR code scanner 33 and sends it to the controller 31. Among them, the QR code information includes the account ID and security authentication information of the ticket.

[0071] Specifically, the second reader 32 includes a key module, which includes several terminal security control module cards (PSAM cards), and the PSAM cards store process keys and algorithms used when encrypting or decrypting data. The key module decodes the QR code using the process key.

[0072] The reader is compatible with multiple ticket types of rail transit and can also be used to identify IC cards and NFC-based terminal devices. IC cards include contactless IC cards, and NFC-based terminal devices include NFC-based mobile bank card payments.

[0073] The controller 31 is used to authenticate the validity of the QR code information according to the account authentication code, and establish a communication connection with the online platform 6 when the authentication is successful.

[0074] Specifically, the controller 31 also verifies the legitimacy of the account ID and the private key signature of the issuing agency in the QR code information. If the verification is successful, a communication connection is established with the online system platform through the TCP protocol. After the authentication is successful, the controller 31 can determine the entry and exit business according to the account status returned by the online platform 6. It should be noted that if the QR code needs to be re-entered, it needs to be updated on the semi-automatic ticket vending machine 2 again.

[0075] The controller 31 releases the blocking mechanism according to the entry and exit status returned by the online platform 6 , and generates a transaction result message which is uploaded to the clearing subsystem 7 through the station subsystem 4 .

[0076] The clearing subsystem 7 performs ticket settlement according to the transaction result message and the preset settlement rules. The transaction result message includes the ticket transaction details of the account of the automatic ticket vending machine device 1. The clearing subsystem 7 combines and counts the ticket transaction details.

[0077] When verifying whether a paper QR code one-way ticket is valid for passage, the verification content should include key elements such as signature, validity period, whether it has been used, and ticket price. If the gate machine 3 cannot communicate with the online platform 6, it will downgrade to communicate with the station subsystem 4 to determine the station-level business validity of the ticket. If it cannot communicate normally with the station subsystem 4, it will downgrade to the terminal device to verify the device-level ticket validity.

[0078] The semi-automatic ticket vending machine 2 is used for the issuance, status analysis and update of paper QR code tickets.

[0079] Specifically, the semi-automatic ticket vending machine 2 initiates a ticket purchase request by communicating with the online platform 6, receives the paper QR code information, and prints the QR code information on a new paper ticket in conjunction with the second printer module 23.

[0080] When the gate machine 3 reads the paper QR code ticket information but fails to open the door as expected, the semi-automatic ticket machine 2 obtains the account information of the paper QR code through the second QR code scanner 21, communicates with the online platform 6 system and initiates an analysis request. The online platform 6 returns the current status information of the QR code, and the semi-automatic ticket machine 2 receives and displays the relevant information for code status analysis.

[0081] If the code status is incorrect and can be updated, the semi-automatic ticket machine 2 initiates a code status update request to the online platform 6 to reset the entry and exit status of the paper QR code account. The gate 3 reads the paper QR code ticket information again and successfully opens the gate to let the ticket pass. It should be noted that the ticket sales and update of the semi-automatic ticket machine 2 will upload the ticket sales and update result message to the clearing subsystem 7.

[0082] In a preferred embodiment, the QR code information includes at least account information and security authentication information. The controller 31 is also used to verify the legitimacy of the account information in the QR code information and the private key signature of the issuing agency in the security authentication information. The controller 31 verifies by establishing a communication connection with the online platform 6.

[0083] In a preferred embodiment, the online platform 6 performs a code issuance operation according to a request sent by a received terminal device, generates QR code data in an encrypted manner, and each paper QR code one-way ticket corresponds to unique QR code data, and the QR code data includes a unique ticket number data field.

[0084] Specifically, the online platform 6 is used to generate the QR code data of the paper QR code single-trip ticket and verify the validity of the paper QR code single-trip ticket; the QR code data follows the principle of one ticket one code, and the QR code data of each ticket is unique, and the ticket number data field contained therein is unique;

[0085] In a preferred embodiment, the format of the two-dimensional code data includes a business data part and a signature part. When the online platform 6 generates the two-dimensional code data, the business data part is digitally signed according to the issuance key private key, and the digital signature adopts the SM2 national encryption method.

[0086] Specifically, the QR code data format in the paper QR code one-way ticket includes a business data part and a signature part. When generating the QR code data, the online platform 6 digitally signs the business data part according to the issuance key private key to prevent the QR code from being tampered with. The signature adopts the SM2 national secret algorithm;

[0087] The second reader / writer 32 of the gate machine 3 downloads the public key parameters corresponding to the paper QR code one-way ticket, and uses the public key parameters to verify whether the business data part and the signature part of the scanned paper QR code one-way ticket are legal, and then performs other business verifications;

[0088] In a preferred embodiment, the two-dimensional code data is a QR Code code or a binary invisible character representation.

[0089] In the present invention, the automatic ticket vending machine device 1 has a wide range of applications and can replace most of the one-time prepaid tickets currently used in stations, such as single-trip tickets and emergency exit tickets.

[0090] In the present invention, each station is equipped with at least one station subsystem 4, one automatic ticket vending machine 1, one semi-automatic ticket vending machine 2, and at least one gate 3. All the automatic ticket vending machines 1, semi-automatic ticket vending machines 2, and gates 3 of each station are connected to the station subsystem 4 of the station, and the station subsystem 4 of each station is connected to the central subsystem 5. The station subsystem 4 can summarize the transaction result messages generated by all the terminal devices of the station and send them to the central subsystem 5, and the central subsystem 5 can summarize all the transaction result messages obtained by all stations and send them to the clearing subsystem 7. The clearing subsystem 7 can record the consumption amount of each account, and the account background loads the consumption amount at the end of the day (or at the end of the month, the end of the year, etc.) when settling.

[0091] The above description is only a preferred embodiment of the present invention, and does not limit the implementation mode and protection scope of the present invention. For those skilled in the art, it should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
