摘要
采用以m序列为基础生成的周期编码对地铁列车的运行线路进行位置编码标定,通过车载检码单元对沿线的标定码进行检码,获得列车实时位置信息,实现精确定位。基于周期编码的地铁列车精确定位技术,提高了地铁列车的定位精度、可靠性和抗干扰能力,成本较低。
Using cycle codes based m sequence to position code and calibrate for running line of metro train,detects calibrated code along the line by vehicle detecting unit,obtain real-time position information of train,and implement pinpoint.Metro train.pinpoint technology based cycle codes,improved locating precision,reliability and anti-interference ability of metro train,it was cheapend the cost.
