一种基于多传感器融合的冗余测速测距系统设计

Redundant speed measuring and ranging system based on multi-sensor fusion

测速测距系统的相关设备是城市轨道交通列车控制系统关键设备。对测速测距系统设计的需求和技术背景进行分析和研究,设计了一种基于头尾冗余的测速测距系统硬件架构,实现了双端车载测速传感器的安全冗余,继而提出了采用多传感器融合应用技术的列车测速测距系统设计方案。

The related equipment of speed measuring and ranging system is the key equipment of train control system in urban rail transit. Through analyzing and researching on the design requirements and technical background of the speed measuring and ranging system of urban rail transit, a kind of hardware architecture of the system based on head and tail redundancy was designed to implement safety redundancy for on-board speed sensor of double end. Then the design scheme of the train speed measuring and ranging system using multi sensor fusion technology was put forward.
