摘　　要：针对国内城市运营BRT(快速公交)系统后出现的问题,为更有效合理地实现对BRT车辆的调度,减少BRT车辆对道路上其他车辆运行造成的影响,提出了一种新型的基于ARM9内核嵌入式平台的BRT监控系统,该系统结合GPS(全球定位系统)、GSM(全球移动通信系统)和GIS(地理信息系统)等无线通信及无线定位技术,可实时展开对BRT车辆的位置、车况、站台信息等数据的采集、传输和反馈过程,有效提高了城市主干道BRT监控系统调度的效率和合理性,增强了行车安全。分析了该系统的运行原理和关键技术,给出了系统软件和硬件的设计方案及未来改进方向。Aiming at the problem of BRT system which is being studied and operated in major cities, for supervising the BRT vehicle more efficiently and rationally, and reducing the influence to other vehicles on the road caused by BRT vehicle, a new BRT supervisory system based on ARM9 platform, which integrates the technology of wireless communication and wireless location like GPS, GSM and GIS, and which can collect, transfer and feedback the data such as the location of the bus, the vehicle condition and the platform condition at the real time, so as to enhance the scheduling efficiency and rationality of the BRT supervisory system and also improve traffic safety is proposed. The paper analyzes the working principle and key technology of this system, and presents the hardware and software design as well as the possible improvements in future.
