中文摘要：

采用北斗卫星定位结合无线传感器网络和移动互联网等技术提出了一种城市智能公交系统。考虑到公交车在行驶中可能出现的高层建筑物遮挡等因素导致卫星定位无效的情况，设计加入了6轴姿态传感器，运用航位推算算法辅助定位。系统能够实现智能进站判断，自动语音报站，智能站牌提示，调度中心远程监控，手机查询车辆位置信息等功能。实际测试结果表明：在卫星定位无效，公交车行驶速度不大于60km／h时，推算定位精度平均达到0．88m，精度远高于北斗接收机的3m，符合设计要求。该系统运行稳定，设备性价比高，为进一步促进城市公交系统智能化发展提出了参考性方案。

英文摘要：

Beidou satellite positioning using combined Wireless Sensor Network and mobile internet technology to design a proposed urban intelligent transportation system. Taking into account the high-rise buildings may occur in the bus with other factors cause the satellite positioning block is invalid,designed to join the six-axis attitude sensor, using the dead reekoning algorithm, assisted positioning. This system can be achieved smart judging, automatic voice new station, smart tips stop sign, dispatch center remote monitoring,phone inquiries vehicle location and other functions. The actual test results show that： in satellite positioning invalid, bus travel speed of not more than 60 km/h,the projected positioning accuracy average of 0. 88 m, while the Beidou receiver positioning accuracy of 3 re,meet the design requirements. The system is stable,equipment cost-effective, in order to further promote the development of intelligent urban transit systems made reference programs.
