高铁因每天清晨需要6h的空窗期维修时间而无法通行,社会的发展需要减少空窗期时间来提高高铁运转效率。传统的基于北斗卫星导航系统(BeiDou Navigation Satellite System
BDS)的高铁铁轨路基的形变监测系统需要一天的观测时长对路基进行精确的监测,这远超高铁空窗期的观测时长无法对提高高铁运转效率起到作用。针对这种情况,在原形变监测解算算法上加入粒子滤波算法,尝试将观测时长缩减到高铁空窗期内;同时,在采样数据大幅度下降的情况下确保解算的监测点坐标值满足高铁路基的定位精度要求。本文利用广汕高铁的BDS形变监测系统的实测采样数据进行实验仿真,验证了粒子滤波算法加入后的有效性。实验结果表明,在粒子滤波算法加持下,观测时长缩减到15 min可确保监测点解算坐标值的

3个方向精度均满足高铁路基定位的±5 mm精度要求,为减少高铁空窗期时间,提升高铁运转效率提供了有效的方法和思路。
High-speed rail needs 6 hours of repair time in the early morning every day
when it cannot be used. However
with the development of society
it is necessary to reduce the window time to improve the operation efficiency of high-speed rail. The traditional deformation monitoring system of high-speed railway track subgrade based on BDS (BeiDou Navigation Satellite System) needs one day observation time to accurately monitor the subgrade
but such observation time during the empty window period of ultra-high railway cannot play a role in improving the operation efficiency of high-speed railway. Particle filter algorithm is added to the original deformation monitoring algorithm. While trying to reduce the observation time to the high-speed railway empty window period
the particle filter algorithm is used to ensure that the coordinate values of the solved monitoring points meet the positioning accuracy requirements of the high railway base under the condition that the sampling data decreases substantially. An experimental simulation is carried out using the measured sampling data of BDS deformation monitoring system of Guangzhou-Shantou high-speed railway
and the effectiveness of particle filter algorithm is verified. The experimental results show that
with the help of particle filter algorithm
the observation time reduced to 15 min can ensure that the a
B and H coordinates of the monitoring points meet the accuracy requirement of ±5 mm for high railway base positioning
which provides an effective method and idea for reducing the time of high-speed railway gap period and improving the operation efficiency of high-speed railway.
