Mobile WebSiteWith the rapid development of urban transportation in China, 15 cities in the country with more than 3 million people have applied for the construction of subways and urban light rail roads. The total length of the lines is 430 kilometers, and the construction investment needs 140 billion yuan. The state will continue to approve the start of the project based on fund raising and localization of rail transit equipment. Among the cities that have been built in these cities are Beijing No. 1 and No. 2 (sales/check-in equipment is not on) and Shanghai (automatic sale/check-in using American equipment).
In recent years, the cities that have passed the national approval and started construction in the near future include Shenzhen, Guangzhou, Chongqing, Beijing No. 3, Beijing No. 4, Beijing No. 5, Shenyang, Changchun, etc., and their vending/checking equipments are in the selection stage. However, due to the lag in China's technology, all cities have followed the US, Japan or South Korea magnetic ticket model. The magnetic ticket technology developed in the 1970s. The automatic ticketing/checking system equipment around the magnetic ticket has been used for a long time. It is technically mature, but its operating cost is high, which hinders its further promotion. There is three:
1. The cost of magnetic ticket is about RMB 1 per piece. It is not suitable for one-way ticket use in China. The cost of a ticket accounts for 1/4 or even 1/2 of the sold fare. It is impossible for the operating unit to accept it. Mode (Shanghai Metro), but it brings about the need to disinfect the ticket, provide reimbursement vouchers, and the problem of emptying and distributing the stations after the ticket is collected, which increases the burden on the operating unit.
2, the vending/checking system should frequently contact/read the magnetic ticket
It is inevitable to invest a lot of manpower and resources every day to degauss and clean the magnetic head.
3. The automatic ticketing/checking system of magnetic ticket has high cost and high requirements for maintenance personnel. In view of the characteristics of urban light rail transit development in China, reducing the cost of ticket sales, improving the performance of the automatic sale/check-in system and strengthening the anti-counterfeiting efforts, we propose the application scheme of the automatic sale/check-in system based on the two-dimensional barcode technology and paper ticket anti-counterfeiting technology.
First, the treatment plan for the ticket
On the ticket, we introduced the concept of encrypting 2D barcodes and fluorescent security points. The ticket is processed without changing the size of the ticket size of the original railway ticket.
In terms of anti-counterfeiting materials, we recommend the method of printing fluorescent anti-counterfeiting points on the ticket face, because: the ticket price of the railway ticket is not high, the automatic sale/check-in place is concentrated and fixed, and the fluorescent ink material can be used to process the ticket surface. Moreover, the cost of anti-counterfeiting printing for a single ticket is only about 3%. Secondly, the fluorescent material responds quickly to the excitation light, and the recognition of the emitted light is simple and fast.
On the basis of the fluorescent anti-counterfeiting point, we apply the automatic two-dimensional bar code on the ticket printing paper of the anti-counterfeit fluorescent dot in the automatic ticketing system for the requirements of the automatic ticket checking system. This is because: 1. If the anti-counterfeiting strength of the single anti-counterfeiting material is not enough, the fluorescent dots are easily forged, thus losing the value of anti-counterfeiting; and the combination of the encrypted two-dimensional bar code and the fluorescent anti-counterfeiting point can fully exert the two-dimensional The characteristics of bar code and fluorescent materials improve the anti-counterfeiting intensity and increase the difficulty of fraud. 2. Give full play to the characteristics of large storage of 2D barcode information, fast automatic recognition, high reading efficiency and strong error correction capability, improve the processing speed of the ticket checking system and ensure the reliability of authenticity, which is conducive to the automation of railway tickets. Detection. 3, the size and length of the 2D barcode can be adjusted freely, can be printed in the blank space of the ticket, avoiding the big change and redesign of the ticket. 4. Printing the 2D barcode on the ticket basically does not increase any production cost of the railway ticket, and meets the special requirements of low ticket fare and high anti-counterfeiting requirements.
Therefore, for the on-site printing of the two-dimensional barcode in the ticket, it should be clear and clear, and can be recognized by the two-dimensional barcode reader (the bar code is the best in black and white). Current laser 2D barcode readers are capable of identifying 2D barcodes printed by almost all different printers. For the ticketing system, the only technical requirement for the printer is that the printing speed must be fast. For this, we design the ticket printing system to pre-print some fixed information of the ticket surface on the ticket paper by printing method, which can reduce the printing amount and increase the printing speed.
In short, if the anti-counterfeiting point and the encrypted two-dimensional bar code technology are adopted in the design of the ticket, the production cost of the ticket is only a few cents more than the previous cost. It can be said that this is the most economical anti-counterfeiting security solution.
Second, the vending / check ticket system structure
The ticket selling end of the vending/checking system mainly includes: touch screen system, automatic banknote recognizer, coin automatic identifier, two-dimensional barcode printer, automatic ticket issuing machine, ticket generation software system, and encrypted two-dimensional barcode automatic generation application software system. composition.
The ticket checking port of the vending/checking system mainly includes: a fluorescent anti-counterfeiting point detector, a two-dimensional bar code reader, an automatic ticket checking channel, an encrypted two-dimensional bar code decryption, and an authenticity discriminating application software system.
Third, the automatic selling / ticket checking system working principle and function
The vending/checking process for the vending/checking system is:
Through the touch screen system to accept the ticketing instructions, after the coin-operated port accepts the coin, the automatic currency identifier automatically recognizes and changes the zero, and simultaneously encrypts the two-dimensional bar code to automatically generate the application software. The ticket number, the ticketing site, the boarding date, and the ticket amount are immediately added. The data information such as the amount, the bus number, and the passenger zone are encrypted by the ARGOXI-64 encryption algorithm and the encrypted 2D barcode is generated. The 2D barcode printer encrypts the encrypted 2D barcode and the ticket number generated by the 2D barcode automatic generation software. On the ticket paper on which the anti-counterfeit fluorescent dots have been printed, the ticket is sold by the automatic ticket issuing machine.
In the ticket detection port, the anti-counterfeit fluorescent dot detector first performs primary detection on the anti-counterfeit fluorescent spot on the ticket, and the two-dimensional barcode reader scans the encrypted two-dimensional barcode, and the encrypted two-dimensional barcode decryption software restores the encrypted data to the original data. After checking and verifying the information such as the ticket number, the bus stop, the boarding date, the ticket amount, the boarding section, and the bus number, and verifying the authenticity, the authenticity result is displayed on the screen. If true, then Show welcome screen
