摘要
应用线性回归方法对管道泄漏信号检测 ,并且对管道泄漏特征信号回归处理的结果以残差方式估计 ,对准确检测管道泄漏特征信号具有明显的效果。为了提高泄漏检测准确度 ,可以进行二次或三次回归平滑管道正常运行时的微小压力波动。
The application of linear regression is used to detect pipeline leaking signal,and to estimate the result of linear regression of the feature signal of pipeline leaking in the way of residual error.It has an obvious effect to detect the feature signal of pipeline leaking.For improving the precision of detecting pipeline leaking it is put up that twice or thrice regression and smoothness the minuteness pressure wave of running normally.
