中文摘要
      针对现代有轨电车受运营环境影响,在运行过程中具有一定安全隐患,提出毫米波雷达作为有轨电车异态检测优选手段,并设计辅助安全防护功能,在此基础上,建立新型辅助安全防护算法.提出一种基于异态检测的有轨电车辅助安全防护技术,通过前向检测器实时检测前方轨道障碍物信息,并通过坐标匹配获取前方障碍物与轨道限界的相对位置情况,对于侵入轨道限界的障碍物确定其与列车的轨内距离,实时计算列车防护曲线,可以提前200m距离向驾驶员提供避撞预警信息.仿真试验结果验证了该方法的有效性,能够基于检测器数据实时提供列车防护信息.
英文摘要
      For the fact of the modern tram’s potential safety risks in different environments, we proposed a millimeter-wave radar as the optimized method for modern tram obstacles detection and designed auxiliary safety protection function. Then, a new auxiliary safety protection algorithm was established. A modern tram auxiliary safety protection technology based on obstacles detection was also proposed with the information of anterior obstacles by the detector, and the location of obstacles and relative location of tram rail by coordinate matching. For the obstacles in the range of tram rail, this research could calculate the distance between tram and obstacles and compute train protection curve dynamically, therefore, the warning information could be delievered to the driver. Finally, the results of simulation experiments proved the research, which could provide the dynamic protection information based on the detective data. Key words: tram; obstacle detection; auxiliary safety protection; train protection algorithm
