摘要
在城市的交通系统中,公共交通系统毫无疑问是其中的重要组成部分,欲缓解日益严重的城市交通拥堵现象,改善乘客的用户体验,公交系统智能化是一种有效解决途径。设计了一种基于先进精简指令机(advanced RISC machines,ARM)的智能公交系统,该系统以ARM为处理器并将GPS、GSM、RFID等技术有效融合,给出了实现智能交通的系统解决方案。首先,在详细分析系统所需性能指标的基础上制定系统的总体设计方案;然后,根据各功能模块的工作原理,给出了智能车载终端和智能站牌终端的设计方法,并完成了系统硬件电路设计;之后,给出了智能公交系统的软件设计方法和实现流程;最后,搭建了系统调试平台并进行调试,对调试过程中需要注意的问题进行了说明,给出了主要功能模块的详细调试过程以及调试过程中的部分调试结果。测试结果表明,所设计的系统可以满足实际应用的需求。
In the urban transport system, there is no doubt that the public transportation is an import part of it. The advanced public transportation system is an effective way to ease the traffic congestion and improve the experience of passengers. In this paper, an advanced public transportation system based on ARM was developed by combining the advanced GPS, GSM and RFID technology together. First, the overall scheme of system based on the detailed analysis of the performance of the project was developed. Then, according to the wording principle of each function module, the design approach of the intelligent vehicle terminal and the intelligent stop board terminal were intro-duced. Then the hardware circuit design was competed, and then the software design and the implementation flow of the system were given. Finally, a platform of the system was built to debug and detail the key issues in the process of achieving the main function modules and some of debugging results was derived. The test result proves that this intelligent transportation system ,meet the need of actual application.
