The train positioning technology based on absolute position encoding is proposed. The absolute positions of the rail track are encoded with the m sequence. The biconditional markers placed on the rail track are detected sequentially by the train-borne reader. The exclusive position code consists of the binary information in the shift register. The absolute train positioning information can be extracted by decoding this position code.

利用m序列（最大周期线性反馈移位寄存器序列）对轨道线路上的绝对位置进行编码，当列车在线路上运行时，通过车载阅读器顺序检测设置在轨道线路上的二值标记，在不同位置上读到的标记在移位存储器中构成唯一的位置编码，以此位置编码值作为地址与车载阅读器所处位置的坐标信息相对应，就可以实现列车的绝对定位。
