摘要
为了提高城市公交的运营效率和服务质量,让乘客及时了解公交车实时车况,设计了一种基于S3C2416微处理器的新型公交电子站牌系统,并对该系统的组成、工作原理、关键技术及主要模块的软硬件设计进行了详细的阐述。系统以ARM为嵌入式硬件平台,采用当前先进的嵌入式技术和GPRS无线网络通信技术,实现了车辆到站预报、车辆到站提示、公交站点查询、公交车次查询等功能。测试结果表明,该系统性能良好、实时性强、稳定性高,具有巨大的市场价值。
A new type of electronic bus-board system based on the microprocessor S3C2416 is designed to improve the efficiency and service quality of urban public transportation and make passengers keep abreast of the real-time situation of vehicle. Then a detailed description of the system is given, including the formation of the system, working principle and key technologies of the system and the design of software and hardware for the main modules. The system takes ARM as the embedded hardware platform, using advanced embedded technology and GPRS wireless network communication technology, which has realized many functions such as prediction of vehicle arrival, notice of vehicle arrival, bus stations query,bus trips query and so on. Test results show that the system has a superior performance with powerful real-time transmis- sion and high stability,which has a widespread application prospect.
