摘　　要：现有自动化监测系统普遍未考虑基准网变形和环境因素对监测数据的影响,自动化监测成果可靠性相对较差。鉴于此,采用平均间隙法对基准网稳定性进行检校,识别并更新基准网中的动点,通过实验验证算法的可靠性,得出设站点的位移变形对监测结果的影响远高于单个后视基准点变形影响的结论;设计固定参考基准差分改正算法,实时改正气象环境因素对监测点斜距、高差和水平角的影响,并设计实验方案模拟工程现场实际工况,验证了算法的可行性。将两种算法应用于某基坑自动化监测项目中,并将算法改正后的监测数据与人工校核数据进行对比,以验证其适应性和可靠性。算法大大提高了自动化监测系统的监测精度,为基于测量机器人的自动化监测系统优化提供了参考。The existing automatic monitoring systems generally do not consider the influence of reference network deformation and environmen-tal factors on the monitoring data,and the reliability of automatic monitoring result is relatively low.In view of the above problems,we adopted the average gap method to check the stability of reference network,identified and updated the moving points in the reference network,and designed experiment to verify the reliability of algorithm.The result showed that the influence of displacement and deformation of station on the monitoring results was much higher than the deformation of a single rear-sighted reference point.Then,we designed a fixed reference differential correction algorithm to correct the influence of meteorological environmental factors on the slope distance,height difference and horizontal angle of monitoring point in real time,and designed an experimental plan simulating the actual working conditions of engineering site to test the feasi-bility of this algorithm.We applied the two algorithms to an automatic monitoring project of foundation pit,and compared the automatic monitor-ing data corrected by algorithms and the manual calibration data to verify the adaptability and reliability of two algorithms.These algorithms can greatly improve the monitoring accuracy of automatic monitoring system,and provide a reference for the automatic monitoring system optimiza-tion based on the measuring robot.
