内容简介：

摘 要在日常生活中，现金交易的不易携带、容易丢失、流通不方便情况给人们生活带来了很多不利，现代化城市开始朝着一卡通方向发展。IC卡则为近几年才出现的新型卡片，在卡片上嵌有IC（E2PROM，有的还有CPU）。由于它保存的信息比较可靠安全、可以高达几万次的读写，所以大量应用于公交车票 、饭票 、保健卡、收费系统等。 众所周知，城市公交系统是一个城市的窗口，其工作的质量与效率会直接影响到人民群众的日常生活和工作。利用现代计算机和通讯技术，实现公交IC卡收费系统能显著提高企业的现代化管理水平，为公交运营管理提供科学准确的数字信息，获得明显的社会和经济效益，同时也为城市一卡通打下基础。本文设计的基于USB接口的车载IC读写器由MCU系列的MC68HC705J2单片机、MMM微模块、键盘、显示、存储器AT93C46、天线和监控电路以及与PC机通信的CH371固化USB串行通信接口电路组成。具有读写时间快、可以1万次写/擦除、数据保留十年、热插拔功能等显著特点。关键词：IC卡、MCU单片机MC68HC705J2、存储器AT93C46、CH371 HD7279ATitle: Bus carry IC cards control system with USB interfaceAbstractIn daily life, the cash transactions inconvenient to take along with people, easy to lose and inconvenient for circulation make a big disadvantage to human life. The IC card is a new kind of card that appears these years. On the card there is a IC (E2PROM, some has CPU). Because the dependable safety in information that it keep, can be up to reading and writing for ten thousand times, large quantity of IC card applies in the bus ticket, meal ticket, care card and charges system etc. Know to all, the city bus system is the window of a city, its work efficiency and quality will affect directly with the daily life of people。Based on the modern computer and communication technology we can achieve the IC card charging to the bus system. This will raise the modernization level of the business management a, achieve social and economy beneficial and make a good base to the one -card citys system. This text design the USB interface car carries IC reads and write system that use the MCU single chip computer MC68CH705J2CH371, MMM micro module, keyboard, moniter,AT93C46, antenna, control electric circuit and with a USB electric circuit constitutes for communication with PC. It is fast writing and reading speed and may write and clear for 10 thousand times. The data will st
