摘 要: | 大坝安全自动化监测过程中,大量数据中的异常值识别已成为亟待解决的难题。将一种较为实用的识别方法——数据跳跃法进行改进,并利用Matlab进行编程实现。通过对某混凝土重力坝自动监测数据进行处理验证,证明此改进数据跳跃法更准确实用。

Improved Data Jump Method on Identification of Outliers in Dam Automatic Monitoring |
| |
Abstract: | Abstract: In the process of dam safety monitoring automation, identification of outliers of large data has become a problem to be solved. A more practical method of identification, data jump method, is improved and realised through Matlab programming. Through the data verification of a concrete gravity dam automatic monitoring, the improved data jump technique is proved to be more accurate and practical. |
