摘要
通过对负压波产生、流体参数测量及波形模式识别原理的分析 ,阐述了采用负压波分析的方法对油管泄漏进行检测和诊断的可行性 ,并提出了与负压波分析相结合的上下文无关文法 ,最后举例说明了这种方法的实际应用。
Based on the analysis of occurrence of negative pressure wave, meterage of hydraulic parameter and pattern recognition method of wave, the feasibility of leak detection and diagnosis of fuel pipe by analyzing negative pressure wave is discussed And the measure of context free grammars is introduced, associated with negative pressure wave The example of the approach in practical application is particularized finally
