查询词典 positioning

The train positioning technologies in urban rail transit are analyzed. According to the characteristic that train runs circularly along fixed rail track, train positioning technology based on absolute position encoding is proposed to the closed-loop track railway in urban rail transit. The single biconditional marker, whose value is 0 or 1, is placed on each position of rail track.

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。
