摘　　要：为了解决在朔黄铁路综合检测列车检测过程中,检测数据时空基准统一的需求,检测列车采用了融合电子标签、GPS和网络授时技术的定位同步系统,通过GPS授时和检测列车精确定位,并通过专用网络,实现了全车各检测系统在时间和里程上的同步。该定位同步技术的实现,使得综合检测列车多专业检测系统在同一时间、同一里程截面处的检测数据得到了统一,为精确定位伤损里程位置、多专业整合分析同里程断面处线路病害状态及原因提供了必要条件。In order to meet the needs of unification of inspection data space-time standard during the inspection process of comprehensive inspection train,location synchronization system which fuses electronic tags,GPS and network time service technique has been adopted,and then GPS time service and accurate positioning have been realized.At the same time,all the inspection systems of comprehensive inspection train have realized synchronization in time and mileage through dedicated network.The realization of location synchronization technique enables all the inspection systems of comprehensive inspection train to unify the inspection data in same time and mileage.All these provide the necessary conditions for accurate positioning of mileage of rail breakage and multi-specialty confluence analysis of breakage conditions and reasons.
