AFC system, the full name is Automatic Fare Collection System, refers to the urban rail transit automatic fare collection system. The system is a closed automated network system with automatic ticketing (including semi-automatic ticketing), automatic ticket inspection, automatic charging and statistics controlled centrally by a computer.

The AFC automatic ticketing and ticketing system is based on computer, communication, network, automatic control and other technologies, and can realize rail transit ticketing, ticketing, billing, charging, statistics, sorting, and management through automation.

The structural hierarchy of AFC

The structure of AFC is divided into layers, including tickets, station terminal equipment, and station computers. There are five levels: system, line central computer system and clearing system. The hierarchical structure is based on the fully closed operation mode, based on the metered charging model, using non-contact IC cards as the ticket medium, and is divided according to the respective functions, management functions and locations of the equipment and subsystems at each level. of. The five-story structure type that has been determined is based on my country's national conditions and urban development status, and comprehensively considers the characteristics of rail transit construction (such as multiple and complex lines, long construction cycles, multiple owners, etc.), and has certain advantages. Scalability. The functions and requirements that must be realized at each level are stipulated as follows:

• The first level - ticket, the fare payment medium held by passengers;

• The second layer - station terminal equipment is installed in the station hall of each station, providing equipment that directly provides ticket sales and check-in services to passengers, and stipulates the technical requirements for station terminal equipment and its operation and management;

• The third layer - the station computer system, its main function is to monitor the status of the station terminal equipment on the second layer, and collect transaction and audit data generated by the station, and stipulates the data management of the system , technical requirements for operation management and system maintenance management;

• The fourth layer - line central computer system, its main function is to collect transaction and audit data generated by the AFC system of this line, And transmit this data to the urban rail transit clearing system and perform reconciliation with it, stipulating the technical requirements for ticket management, operation management and system maintenance of the line;

• The fifth layer - the clearing 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, conduct data sorting and reconciliation, and be responsible for It connects the urban rail transit AFC system and the urban card clearing system, and stipulates the technical requirements for ticket management, ticketing management, operation management and system maintenance management.

In the automatic ticket gate system, multiple serial port applications are required, such as automatic ticket throughput ports, non-contact IC cards, display screens for displaying prompt information, and blocking device controllers , central controller, alarm, etc., and also require network ports, USB interfaces and system terminals for information communication.
