摘要:
车辆定位技术是有轨电车运行控制系统的关键技术之一。针对传统GPS(全球定位系统)定位技术存在的缺点，结合有轨电车的运营特点和定位需求，提出了以BDS(北斗卫星导航系统)定位为主、以“IMU(惯性测量单元)+轨道电子地图”定位为辅的有轨电车车载组合定位方案。对该组合定位方案进行了仿真测试，结果表明：组合定位系统可以保证有轨电车的精确、连续测速定位，可为有轨电车车辆定位提供了一种低成本、有效的解决方案。
Abstracts:
Vehicle positioning technology is one of the key technologies of tram operation control system. Targeting the disadvantages of conventional GPS (global positioning system) positioning technology, combining the operating characteristics and positioning needs of trams, a tram onboard integrated positioning scheme based on BDS (Beidou satellite navigation system) positioning and supplemented by ′IMU (inertial measurement unit)+Track Electronic Map′ positioning is proposed. Simulation test is carried out on the integrated positioning scheme. Results show that the integrated positioning system can ensure the accurate and continuous speed measurement and positioning of the tram, providing a lowcost and effective solution for tram vehicle positioning.
