The invention relates to a high-speed maglev train positioning anti-shake method and system. The method comprises the following steps: firstly, acquiring two square wave signals output by a relative position sensor; a time sequence processing circuit is arranged, the two paths of square wave signals are processed through the time sequence processing circuit, and when the first square wave signal in the two paths of square wave signals jumps, the second square wave signal jumps; and if the jump of the second square wave signal does not exist between the first jump of the first square wave signal and the next jump of the first square wave signal, the jump of the first square wave signal is regarded as an unreasonable jump. Unreasonable jumps in the two paths of square wave signals after time sequence processing are filtered out, and two paths of output signals are obtained; and finally, according to the current running state of the train, combining the edges of the two paths of output signals to carry out cogging counting so as to determine the relative position of the high-speed maglev train. Compared with the prior art, the method has the advantages of avoiding interference generated by jitter, eliminating influence of the jitter from the source, increasing positioning accuracy, enhancing positioning reliability and the like.
本发明涉及一种高速磁浮列车定位防抖方法及其系统。该方法首先获取相对位置传感器输出的两路方波信号;再设置时序处理电路,将两路方波信号通过时序处理电路进行处理,使两路方波信号中第一方波信号跳变时,第二方波信号发生跳变;若一次第一方波信号跳变与下一次第一方波信号跳变之间不存在第二方波信号的跳变,则将该次第一方波信号跳变视为不合理跳变。滤除两路时序处理后的方波信号中的不合理跳变,得到两路输出信号;最后根据列车当前运行状态结合两路输出信号边沿进行齿槽计数,进而确定高速磁浮列车相对位置。与现有技术相比,本发明具有避免抖动产生的干扰,从源头上消除抖动的影响、增加定位准确性、增强定位可靠性等优点。
