基于速度传感器的测速定位系统在轨道交通领域应用广泛。文章介绍速度传感器的测速原理和测速算法,参照IEEE1474.1附件3中提供的列车测速精度、分辨率的典型参数,分析测速精度、分辨率设定的情况下,系统各参数的取值条件,为系统设计者提供一定的参考意见。通过对常用测速定位系统结构的研究,给出基于速度传感器的定位算法,并对影响定位误差的因素进行了简要说明,提出几项减少测速定位误差的改善措施。
The Speed Measurement and Positioning System based on speed sensor is widely used in railway transit field. This article introduced the principle and algorithms for speed measurement, referenced the train speed measurement accuracy and the typical parameters of resolution ratio provided in Appendix 3 of the IEEE 1474.1 Standard, analyzed the value condition of system parameters which could provide a reference for system designers while the speed measurement accuracy and resolution ratio were set. Through the study on the structure of common Speed Measurement and Positioning System, the article given the positioning algorithms based on the speed sensor, explained the factors affecting the positioning error briefly, put forward improvement measures for reducing the error of speed measurement and positioning.
