摘要
随着移动通信技术的不断发展,短消息通信作为 GSM 系统中一种基本的通
信方式,正进入快速增长的时期,利用移动通讯技术实现远程数据传输与控制
具有很高的理论研究价值和广阔的应用前景。
智能公交系统的实现关键在于车辆和监控中心之间的实时通信,这就需要
建立完善的公交信息通信系统。本文建立了一个基于 GSM 短信息通信的公交车
远程数据传输系统,主要包括车载系统和公交监控中心系统两部分,目的是实
现公交车和监控中心间的实时通信。车载系统采用 AT89C52 单片机做主控芯
片,通过向 GSM 模块发送 AT 指令完成数据信息发送,并能接收监控中心的故
障处理信息。并在车载终端控制键盘及液晶 LCD 显示,从而掌握公交车整体运
营情况,为公交车的合理有效的调度提供可靠的依据,提高公交运营效益也方
便市民的出行。最后,通过软硬件设计和调试实验,验证了系统的合理性及可
行性,为智能公交的实现奠定了技术基础。

Bus-Based work Management System
Abstract
With the fast development of mobile munication technology, short
message service as the munication means of the GSM system is stepping up
into a period of fast growth. Using mobile munication technology to
implement remote date transmission and control has high research value in theory and
unlimited application prospect.
The munication between the bus system and the bus monitor
center is the key to the achievement of ITS , so a munication system for
ITS is needed. In this paper, remote wireless data transmission system based on GSM
short message service which consists of the bus system and the bus monitor center is
built, aiming at realizing the munications between the bus monitor
center. The bus system uses AT89C52 as the control chip, it sends mand to
GSM module in order plete the sending of data and failure information, and
receives the failure handing information .It provides reliable evidences for the
adjustment of the bus and improves the benefit foe the operators and provides
convenient for citizens. Finally, according to the rationality and feability , which lays a
technological foundation for the realization of ITS.
