| Abstract: | Adapting filter can remove noise, and exactly draw leakage sign from broad spectrum noise. It provides effective method for accurate, timely and reliable forecast"four pipe"leakage. Structure of Adapting filter and noise cancellation algorithm is introduced in this paper. And it's correctness and practicability is checked by practice. It gives important role to reduce losses caused by enlarged leak accident. |
