摘要
控制精度是保证高速铁路列车正点到达和安全运行的核心。以传感器为核心元件的设计方式是目前高速铁路的测速和定位技术的主流。传感器在高速铁路的测速和定位技术中主要有3种类型:脉冲转速传感器、惯性加速度传感器、独立定位传感器。研究传感器具体应用情况和工作原理。结果表明,传感器测速定位方法简单,经济实用,误差小,适于在高速铁路中普遍应用。
Control precision is the crucial factor to ensure the on-time arriving and safe running of high speed train.Sen- sors, which act as the core component, are now the mainstream mode in speed measurement and positioning of high speed train.Sensors in this field include：pulse rotary speed sensor, inertia accelerator sensor, independent positioning sensor. The paper researches on the operation principle and concrete application of sensors.The conclusion testifies the method of speed measurement and positioning by sensors which have the characters of simpleness, economic, practicality and little error, thus it can be widely applied in high speed railway.
