Software And Hardware Design Of Subway Gate Control System

As a transportation system that can relieve the pressure on the ground,the underground railway is currently in the stage of high-speed construction in China.As an important part of the Automatic Fare Collection System,the subway gates play a role in regulating the entry and exit order of pedestrians and ensuring the revenue of subway operations.Therefore,it is of theoretical and practical significance to study the design principle of the subway gate control system and apply it to practical applications.This paper refers to the five-layer structure system of AFC system,firstly takes some terminal equipment of the site system and some functions of the central computer system as the design basis,then analyzes its design strategy and summarizes it.From the perspective of software and hardware design and the design of upper and lower computers,the implementation principles and implementation methods of the involved links are studied one by one.The completed parts are tested and optimized to ensure the stability of the system,and ultimately achieve the purpose of realizing the hardware and software design of the subway gate control system.This thesis participates in the design for the hardware and software of the subway gate control system,which is roughly divided into two parts: upper computer and lower computer.The lower computer uses stc12c5a60s2 as the main control component,supplemented by non-contact read/write card chip mfrc522,LCD screen,red and green LED light box and other modules,which can realize card reading,card writing,and communication with the upper computer.The upper computer information management system is written by the python built-in tkinter module.The information system can manage users and MetroCards comprehensively.The system is well designed and it has good stability and strong practicability.
