Design and implementation of subway automatic ticketing system based on Verilog HDL

This paper is a synthesis of practical investigation, theoretical analysis and literature reading. Using Verilog HDL language to research a subway automatic ticket selling system. The design of this subway ticketing system takes convenience, quickness and simplicity as the core, and takes saving time for passengers as the guide design. It completes the main process of buying subway tickets for passengers. Firstly, this paper studies the development of subway ticketing system at home and abroad, and then studies the basic components of subway ticketing system. Through Quartus II 13.1 development software to do schematic input mode, this paper designs the subway automatic ticket selling system which composed of ticket selection module, coin calculation module, change processing module and display interface module. The paper also simulates the ticket selection module, coin calculation module, change processing module and display interface module on Quartus II 13.1.
