Speed and Distance Measurement System of Train Control Onboard Equipment Based on Head and Tail Redundancy
测速测距系统主要任务是向列车控制系统提供实时的速度和位移信息,常见的测速测距系统主要采用多传感器(如速度传感器、雷达传感器、加速度计、卫星等)融合的方式.从系统的角度提出一种基于多种传感器融合的首尾冗余测速测距系统设计方案,既能有效地降低因单点故障导致的测速测距系统故障,又能避免因测速测距系统故障而导致的信号系统故障,从而实现了车头、车尾测速测距系统的安全冗余.
The main task of the speed and distance measurement system is to provide real-time speed and displacement information to the train control system.Common speed and distance measurement systems mainly use the integration of multiple sensors(such as speed sensors,radar sensors,accelerometers,satellites,etc.).This paper proposes a design scheme for a redundant speed and distance measurement system based on the integration of multiple sensors from a system perspective.It can effectively reduce the faults of the speed and distance measurement system caused by single point faults,and avoid signaling system faults caused by faults of the speed and distance measurement system,so as to realize the safety redundancy of speed and distance measurement systems in head and tail of the train.
