| 摘 要： | 大坝中的传感器(测点)在信息上存在相互印证关系.首先通过对具有相似变化规律的多个测点的监测数据进行标准化处理,将不同测点在同一时间的一次观测近似看作同一测点在相同观测条件下的重复观测.然后,运用常规统计理论,在大坝安全监控专家系统中实现异常值检测以及异常趋势识别.从而,及时发现大坝潜在的问题,为大坝安全监控提供可靠依据.

| Abstract: | Data acquired by monitoring sensors in dam often can be mutually verified by each other, and the data of different sensor often changes in the same or similar way. The data acquired by different sensors at the same time is normalized and is regarded as data acquired form repeated observation of a sensor under same working condition; then, by use of routine statistical theory in the dam safety monitoring expert system, the data with abnormal change or sensor with abnormal trend change can be detected; thusly, trouble hidden in dam can be found out in time; and reliable evidence is afforded to ensure the safety of dam. |
