1 Overview
This system is designed to meet the actual needs of urban public transportation toll management, combined with network technology, RFID technology, mobile communication technology, and computer information management system, to realize all-in-one card billing and settlement for the consumption of multiple bus vehicles of several bus companies in the area. Intelligent management system.
2. System introduction
2.1. Overall design ideas
The system is based on the establishment of the overall design framework of “taking passengers as the service object, charging management as the purpose, using a variety of information technology as the management means, and combining the people-oriented service concept to realize the IC card integrated management system”.
The information system adopts the B/S system architecture to prepare for the convenience of system expansion when adding exports in the future. The system host is deployed in the telecommunications room, using a fixed IP, which is safe and convenient for management. Since the communication data between the terminal and the host is less, the card issuance and recharge terminal The management computer solves the communication with the remote host through ADSL, and can query the consumption information of each user by means of domain name resolution or direct IP access, and print statements for settlement.
The on-board terminal consumer machine can realize a variety of engineering modes: it can be embedded in a coin box or suspended and fixed in the car. The power supply is 12V DC power supply. It can directly use the in-car power supply. The backup battery can work when the locomotive is stopped. 3 Hours to ensure data loss caused by sudden power failure. The vehicle-mounted terminal can be used offline, or it can communicate with the host computer through GPRS.
The vehicle-mounted terminal and software system developed and designed by our company can identify 8 card types, that is, different consumption amounts can be defined according to different users. As long as the system realizes consumption of 4 card types, it fully meets the requirements.
2.2 Network topology
Based on simple and practical economic construction needs, the front end uses offline user equipment to complete data interaction with IC, daily manual data collection, (optionally embedded in GPRS module, real-time or regular data upload), each card issuance recharge point terminal and telecommunications room ISP is used as an intermediate service to solve the communication. The management user logs in to the remote data server through ADSL. The data server is located in the telecommunications room, using a fixed IP address, real-time communication, same-day settlement, ensuring accurate data; simple and flexible structure, easy for system expansion.
2.3 The overall structure design of the system
In the overall structure design of the system, fully consider the current situation and future system expansion requirements, adopt multi-interface, open frame design; in view of the actual situation of the public transport card, from the reliability, manageability, scalability, development and safety From the perspective of gender, combined with various systems that may be purchased during the system implementation process, this system adopts a client/server architecture. It is used to solve the needs of complex interface, confidentiality, high security, and database modification operations. The database can be defined according to user requirements.
When designing and developing applications, the site and component methods are used. Different services correspond to different functional modules. In addition, when each operator and user accesses a certain system, only applications and related processing data within the scope of their authority appear on the site. Through the customization function of the system, the friendliness and safety of the system can be improved.
First, establish a unified management information platform, form data standardization of various types of information, build an excellent digital space and information sharing environment, and further realize data transmission network, user terminal intelligence, and centralized settlement management;
Second, establish a unified identity authentication mechanism, and at the same time establish a verification management platform based on the unified identity authentication mechanism;
Third, closely integrate various business processes and systems to achieve seamless connection between system functions and business processes, and promote the construction of networked hardware infrastructure platforms in the base;
Fourth, realize unified electronic payment and fee collection management, and realize vertical management;
Fifth, establish an effective interface between various business systems, and finally realize the effective operation of the IC card integrated management system.
Central platform system: It is the core layer of the all-in-one card. It is composed of all kinds of modules such as all-in-one card central database, identity management, transaction settlement management, system management, etc. It mainly comprehensively manages all kinds of application subsystems and hardware terminals of the all-in-one card, and manages business flow and data flow.
Application subsystem: It is the application service layer of the all-in-one card, directly serving users, providing all kinds of application function management of all-in-one card, including card management, comprehensive query, collecting and reading card information of cardholders through equipment, and managing through computer terminal Various cardholder information provides cardholders with various card-related services.
Third-party application interface: The one-card system provides standardized interfaces and open communication protocols to facilitate third-party application subsystems (UnionPay recharge, etc.) to access the one-card center platform through a unified application interface to realize data sharing and data exchange.
3. Functional goals of system construction
The ultimate goal of system construction is to build a true “IC card integrated management system system platform”. After continuous construction in phases and phases, the following goals will be gradually achieved:
Realize the application of 8 card categories. You can define student card, senior card, internal employee card, discount card, half-price card, etc.
Card authorization is completed by the head office, and card issuance and recharge points are set up at all bus stations in the city to realize operations such as recharging and refunding the card. The bus company makes unified settlement; realizes the summary of the total consumption of branch companies, and realizes the unified settlement of the headquarters.
Realize offline vehicle terminal application, terminal can be customized structure appearance, dual-screen display, voice prompts, etc.
Realize manual aggregation or remote automatic aggregation by vehicle terminal.
Realize the interface construction with other systems in the future, the system can be expanded at any time, and the management can be standardized
