The Design Of IC Card Application In Bus System Based On Linux

Due to the reform and opening up and rapid economic development in recent years, more and more private cars appear on the city roads makes cities growing pressure and environmental pollution is gradually gaining weight. The state encourages green travel which requires the urban public transport can better serve the people. With the rapid development of modern society, the IC card reader becomes important electrical equipment on the bus. It is responsible for billing and data statistics. How to effectively make use of IC card reader to service people in future is a very meaningful topic.This paper analyzes the current status of transit operations and the current state of the bus system. Then put forward a more efficient public transportation system. This system can achieve the function of daily public transport basic billing, after the bus back to the station it can upload local consumption data to the server by wireless network, at the same time, the server can also update the local application over a wireless network, configuration files, and device driver. Traditional IC card reader store programs as the format of firmware, but this system develop the applications beyond operation system. With a wireless network data transmission, it can be easily unified upgraded without changing the hardware of the system.This design is divided into IC card reader design and server software design. The IC card reader designed base on Samsung S3C6410microprocessors and FM1702in hardware. Through Marvell Wi-Fi chip to accomplish the network transmission. Designing device drivers to driving hardware and develop Linux-base applications to accomplish consumption. There is an Application base on Qt running on the server-side. This paper introduces in detail the design content of the whole system, including custom card machine end the Linux kernel and file system, card machine side device drivers are written, card machine and the design of the application and the server database and the software design.Applying this system to the real life, upgrade the public transport system in the future, not only can improve the work efficiency of the public transport system can also provide card machine with strong portability and scalability.
