摘　　要：针对大坝安全监测中自动化测量系统的验证和校核,提出了一种新型的数据比测方法。首先,基于时间序列对人工和自动化观测数据进行测次对齐,降低因样本本身带来的差异性;第二,基于变化阈值统计二者间超差测次的数量和比例;第三,基于方差分析判定二者测量差值是否满足2ζ法则;第四,进行样本相关性及差异性分析,检定二者互相关性的强弱,及在多个显著性水平上差异是否显著;最后,基于谱分析对比二者的规律性如周期、变幅。通过多个维度的比较分析,全面检定人工和自动化测量结果的一致性水平,为自动化监测系统的验证和校核提供了更可靠的依据。A new comparison measurement model is proposed for the validation and verification of automatic dam safety monitoring system. Firstly, both manual and automatic data are aligned based on measuring time to reduce deviation.Secondly, the amount and ratio of overrun-difference data is calculated. Thirdly, whether the difference of two data meets the2ζ law is checked based on variance analysis. Fourthly, the correlation strength and whether the difference is significant on specified significance level are examined. Finally, the regularity of two data such as period and amplitude is compared based on spectrum analysis. By multi-dimension comparing, the validation and verification of automatic dam monitoring system would be more reliable under this model.
