摘　　要：动态精确定位是综合检测列车的关键技术之一,其难点在于校准点对应的精确里程数据库的建立。本文利用目前高速铁路沿线布设的CPⅢ数据资源,采用简单的圆心测量与等分测量方法和数据处理软件,将校准点的里程与CPⅢ测量里程一一对应,建立精确数据库,从而实现了动态精确定位;并在京沪高速铁路K718—K740进行了最高速度为400 km/h的验证试验,动态定位精度可达1 m以内。Dynamic pinpoint technology is one of key technology in comprehensive inspection train,the difficulty of which is establishing accurate mileage database corresponding to calibration point.Based on CPⅢ data resource along the current high-speed railway,this paper gave the accurate mileage database in which one-to-one correspondence between calibration point mileage and CPⅢ mileage was realized by adopting circle measurement method,part measurement method and data processing software.Dynamic pinpoint was realized in the paper and the technology was tested by Beijing-shanghai high-speed railway KM718-KM740 with maximum speed of 400 km/h,in which the dynamic pinpoint precision can reach to 1 m.
