According to the use environment of the scenic spot and the actual operation and management mode, based on the current RFID fare collection management method (open-loop management), the closed-loop management mode is considered from the aspects of safety and reliability, and the RFID fare collection management realizes ticket card anti-counterfeiting, Real-time ticket sales monitoring, anti-leakage and other functions.
1. Ticketing mode
Use C/S or B/S network online ticketing system. The database adopts SQL server, and a PC server is set up for database and application services. You can consider setting up an independent WEB server. According to customer requirements, consider whether to use hot backup. Set up ticketing terminals in the centralized ticketing area. Each ticketing staff is set up independently. The account password or hardware key login system (C/S mode can be considered), the same equipment (B/S mode) is used for temporary ticket sales of remote attractions, connected through the ADSL network, and real-time online ticket sales.
software:
1. Server-side database;
2. Data application server-side management program, including card sales record storage, personnel account management, card validity query (remote service), card swiping data record reception, statistics, report management and other functions.
3. C/S mode (centralized ticket sales) terminal program, including account login, card sales, query, statistics, on-duty report and other functions.
4. B/S mode terminal: IE browser is enough.
advantage:
(1) Ticket card management is simple. Unauthorized ticket cards are invalid cards and can be managed as general IC cards. Only the account of the ticket seller is required to be managed;
(2) Strict management and high security, almost impossible to miss from the perspective of the system.
shortcoming:
(1) Due to the real-time requirements of the system, there is a large investment (servers need at least one master and one backup, and regular maintenance);
(2) Professional information service management personnel are required, and ticket sales personnel need to undergo training and strict account management.
2. Ticket checking mode
1. Gate management machine: Set up an embedded PC to manage the gates at each scenic spot. The PC adopts an industrial-grade PC and is installed in one of the gates. It is equipped with an industrial-grade LCD screen installed in the gate. At the back end, use the small keyboard for query.
Native features:
(1) Collect the gate opening record by swiping the gate through the RS485 interface;
(2) Download the blacklist and encryption key to the gate controller;
(3) Exchange data with the ticketing server, upload credit card records, and receive special data and notifications.
(4) For damaged cards, enter the printing number to query the ticket sales records on the server to determine the authenticity of the card and other functions.
2. Gate controller: The gate controller currently in use is a 51-series single-chip microcomputer, and the following processing needs to be done:
(1) Add a multi-color LED (big round light) indication at the top of the gate, which can distinguish credit card types (such as A-line and B-line tickets) by distinguishing different colors in the sun.
(2) Upload the card swiping record to the gate management machine by adding an RS485 interface, and then upload it to the server from the gate management machine, and at the same time download the blacklist and key through this port. The third is to modify the software of the gate controller to realize the real-time clock, automatically determine the validity date of the card, and increase security.
3. IC card ticket
Currently, the UL card of PHILIPS is used. This card is a radio frequency IC card specifically for ticketing system applications. There is a 7-byte globally unique ID number (unmodifiable) inside. All internal data is encrypted and stored, which is expensive to crack. The safety performance of the project is good.
For some items, the following modifications can be made:
(1) Print the serial number during production, and enter the serial number segment when selling the card (authorization), and the system will automatically generate the index number, which is convenient for checking the legality of the card when a bad card occurs, and avoiding disputes.
(2) Redefine the internal memory of the card and perform coding management for each scenic spot, so that each scenic spot can only be swiped once.
Four, safety management
1. Key system
For example, the original system does not use strict security key management. Strictly speaking, it can unilaterally form a threat to the security system. In order to reduce investment and simplify the system, the combination of software and hardware encryption is used to achieve a security management method that shields each other from multiple parties. That is, a fixed algorithm is used on the device software control end, and a management key is set on the management end (three separate department keys can be used to generate a secret code key through the algorithm), and the key is automatically downloaded to each device point through the server, so The ticket card authorization device and the ticket checking device need to use the same key to unlock the card, so that neither the equipment supplier, the administrator, or the ticket sales link can unlock the ticket card, ensuring the security of the ticket card (even if the administrator goes to another The machine reinstalls the software, and enters his personal key and cannot obtain the same decryption card key; the equipment supplier software compiler cannot obtain the management key and cannot decrypt the card.).
2. Abnormal card monitoring
When the card key is cracked (the probability is very low), there is a card with the correct algorithm without the authorization of the system server, and the card swiping record is uploaded in real time, and the server automatically compares the global unique code ID number to make the server alarm and issue a black in time Check the ticket on the list.
3. Card deadlock handling
Using the special function of this IC card, when it is judged that the ticket card is used for the last time, the LOCK position of the card is locked, causing the card to become a dead card, which can only be inquired and cannot be rewritten to ensure the safety of the card outflow.
4. Real-time authorized ticket sales management
The card is an ordinary IC card before authorization, and the value is only the cost of the IC card. Only when the card is authorized (encrypted by the key system in the server) can it become a securities. There are strict account permissions and record management on the server side. , Any authorization and modification can be verified, according to customer needs, whether to consider whether the record is written to a CD (CD cannot be modified).
5. On-board fare collection system
Use the remaining space of the IC card to write the number of allowed rides, and use the sound and light prompt method to determine whether the card is allowed to ride by querying and rewriting the record (if the record needs to be automatically returned, the server needs to use DTU remote exchange, according to the actual situation , May not be used).
Six, system framework diagram
According to the above modification plan, the list of equipment and software to be added is as follows:
hardware:
1. A set of servers (a combination of database and application servers can be recommended).
2. One 16-port or 24-port switch (used in the ticketing center); one 4-port switch for each scenic spot.
3. The gate management embedded computer (including one LCD screen and one power supply), one for each scenic spot.
4. RS232 to RS485 interface converter, one for each gate.
5. Multi-color LED indicator light (large round light), one for each gate.
6. ADSL dial-up MODEN, one for each scenic spot.
7. Vehicle-mounted card reader and controller, one set per vehicle. If you need data back transmission, you need to add one set of DTU on the server side, add one set of DTU for each car, and one mobile phone card for each DTU, and activate GPRS.
software:
1. A set of database server software, including database copyright.
2. Application server software, including WEB service and domain name resolution.
3. Ticket selling software.
4. Turnkey management software.
5. On-board machine software.
5. Modification of the control software of the handset and the gate.
