With the advancement of urbanization, rail transit has shown positive effects in optimizing urban spatial structure, alleviating urban traffic congestion, and protecting the environment. As China’s rail transit construction enters a stage of rapid development, the core equipment technology of rail transit is becoming more and more perfect. For many years, urban rail transit has been completed through manual ticket sales and manual ticket verification. With the successful application of the subway automated ticketing system (AFC), it has avoided the cumbersome manual change and ticket sales links in the past, greatly saving labor costs and speeding up The ticket sales speed and entrance pass rate have also been increased by more than ten times, adapting to the demand of modern metropolitan subway traffic.
The full name of AFC system is Automatic Fare Collection System, which is based on computer, communication, network, automatic control and other technologies, which realizes the whole process automation system of rail transit ticketing, ticket checking, billing, charging, statistics, sorting and management. The rail transit of foreign economically developed cities has generally adopted this management system and has developed to a fairly advanced level of technology. The automatic fare collection equipment for urban rail transit stations in my country was originally from a foreign country. In recent years, my country has carried out a large amount of research and development work, put forward various forms of products, and the technical level is constantly improving. The development of the domestic rail transit AFC system has gone through a process from scratch. With the development of computer technology and software, the technology of my country’s urban rail transit AFC has been integrated with the city’s all-in-one card, realizing the all-in-one card in cities and even urban areas.
The structure of the automatic fare collection system (AFC) of urban rail transit is divided into five levels: ticket, station terminal equipment, station computer system, line central computer system, and sorting system.
The hierarchical structure is based on a fully enclosed operating mode, based on a metered toll model, using non-contact IC cards as the ticket medium composition principle, divided according to the respective functions, management functions and locations of equipment and subsystems at each level of. The currently determined five-layer structure is based on my country’s national conditions and urban development status, and comprehensively considered the characteristics of rail transit construction (such as multiple and complex lines, long construction period, multiple owner units, etc.). Scalability. The following provisions are made for the functions and requirements that must be realized at each level:
The first layer-the ticket is the fare payment medium held by the passengers, which stipulates the technical requirements for the physical characteristics, electrical characteristics, application file organization and security mechanism of the two types of stored-value cards and one-way tickets;
The second layer—station terminal equipment is installed in the halls of each station to directly provide passengers with equipment for ticket sales and inspection services, and specifies the technical requirements for station terminal equipment and its operation and management;
The third layer-the station computer system, whose main function is to monitor the status of the second-level station terminal equipment, and collect transaction and audit data generated by the station, and regulates the system’s data management, operation management and system maintenance management skills requirement;
The fourth layer—the line central computer system, whose main function is to collect transaction and audit data generated by the line’s AFC system, and transmit this data to the urban rail transit sorting system, and to conduct account reconciliation with it. Technical requirements for line ticket management, operation management and system maintenance;
The fifth layer-the sorting system, its main function is to unify various operating parameters within the urban rail transit AFC system, collect transaction and audit data generated by the urban rail transit AFC system, and perform data sorting and reconciliation, and at the same time be responsible Connecting the urban rail transit AFC system and the city all-in-one card sorting system, stipulates the technical requirements for ticket management, ticket management, operation management and system maintenance management.
System Requirements
The system has the following requirements in combination with the above application site characteristics
1. Application of multiple serial ports
2. Application of multi-channel digital I/O
For example, automatic ticket throughput, non-contact IC card, display screen for displaying prompt information, blocking device controller, central controller, alarm, etc.
3. Network interface, USB interface application requirements, information communication with the system terminal.
4. The demand for low power consumption and good heat dissipation without fan
5. Demand for dustproof and wide pressure input
6. Requirements of high stability and high necessity
