停车场发卡器与IC卡读写器的设计开发

Design and Development of Card Sender and Reader in Parking Lots

介绍了MIFARE1 IC S50非接触式IC卡的结构,描述了停车场管理系统的基本模块及功能。介绍了发卡器的配置卡与用户卡的功能,并给出了2种卡的工作流程。针对IC卡读写器的设计,给出了流程图和硬件电路图,并给出了在PIC16F876单片机上测试通过的程序源代码。文中发卡器与IC卡读写器的设计,依据实际要求还可以开发更多的功能。

This paper introduced the configuration of the untouched MIFARE1 IC S50 Card. MF1 card has sixteen sectors, and each .sector has its own .secret file for a .set of keys for systems using key hierarchies. It described the basic modules and their functions in parking lots management system. This paper introduced the functions of configuration card and user card, and the flow chart was proposed. Configuration card was used to intercalate IC card reader, and user card was used for drivers to get the right to access parking lots. To the design of IC card reader, the flow chart of IC card reader＇ s program and hardware circuit diagram were depicted, and part source codes were also given. These source codes were tested successfully passed in microsoft chip PIC16F876.
