Title: Bus carry IC card’s control system with USB interface
Abstract
In 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 city’s 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 stay for 10 years.
