摘要:

为实现城市公共自行车的自动化租赁及实时调度, 提高车辆的使用效率, 将射频识别技术、GPRS(General Packet Radio Service)无线通信技术与嵌入式技术相结合, 设计了客户机/ 服务器架构下的无线智能租车系统。客户端以S3C2440 处理器为核心并移植了linux 操作系统, 完成车辆的自动化租赁控制并将使用者信息、分布式站点地理信息和终端状态信息以TCP(Transmission Control Protocol) 协议上传到服务器; 同时在Windows 下开发了基于TCP 的服务器应用程序, 以接收客户端上传的数据并统计车辆的分布状况, 必要时做相应的车辆调度。给出了系统的总体设计方案, 并进行了编程调试。测试结果表明, 该系统运行稳定, 客户端的数据通过GPRS 网络可以安全可靠、实时地上传到服务器, 达到了数据实时传输的要求。

Abstract:

In order to realize real-time scheduling and automatical lease of the city public bicycle, and improve efficiency in the use of vehicles, an intelligent lease system is designed based on the framework of client and server, which combined with radio frequency identification, general packet radio service and embedded technology. The client uses S3C2440 processor, and transplanted linux operating system. The client is in charge of the lease of bicycles automatically and transmits user information, distributed sites geography information and terminal state to server in TCP(Transmission Control Protocol); at the same time the server application is developed in windows system based on TCP(Transmission Control Protocol), for the purpose of data receiving
and distribution statistic of the bicycles and making scheduling strategy if necessary. After programming and debugging, the test results show that the system is stable and the client's data can be transmitted to server safely and reliably via the GPRS(General Packet Radio Service) network in real time and achieve the requirement of real-time transmission of the data.

Key words: general packet radio service, radio frequency identification, transmission control protocol(TCP), client/ server, embedded processor
