摘要:
中低速磁浮列车运行时处于悬浮状态，其测速系统与传统轮轨列车的测速系统有所不同。列车测速系统是否能够输出高精度、低延滞、低离散度的速度信号，对中低速磁浮列车的安全运行尤为重要。首先阐述了中低速磁浮列车测速系统采用的传感器计数法的原理，提出该方法在工程实际应用中存在的问题；其次以北京地铁S1线列车测速系统的工程化应用为基础，建立了测速模型，并进行误差分析；最后介绍了北京地铁S1线采用的辅助测速方式，以及速度经修正补偿后的误差情况。
Abstracts:
Medium and low speed maglev train is in suspension during operation, and the speed measurement system is different from that of conventional wheelrail train. Whether the speed measurement system can output high-precision, low delay and low dispersion speed signals is particularly important for safe operation of medium and low speed maglev train. Firstly, the principle of sensor counting method used in the speed measurement system of medium and low speed maglev train is described, and the problems existing in the practical application of this method in engineering are put forward. Secondly, based on the engineering application of Beijing Metro Line S1 speed measurement system, a speed measurement model is established for error analysis. Finally, the auxiliary speed measurement method used in Beijing Metro Line S1 and the error of speed after correction and compensation are introduced.
