Analysis of Diagnostic Techniques for Pressure Fluctuations in Rural Water Supply Networks

摘要:

为提高农村供水管网压力异常事件的识别效率与成因判定能力,文章针对系统运行中频繁出现的压力波动问题,构建了由特征参数识别、波动模式分类、成因归因分析与诊断支持系统组成的成因诊断技术路径。研究结果表明,系统在高扰动频段具备清晰识别能力,诊断准确率达80%,稳定性指数由0.126降至0.078,具有良好的区域适应性与工程可扩展性。

Abstract:

In order to improve the recognition efficiency and cause determination ability of abnormal pressure events in rural water supply networks, this article constructs a cause diagnosis technology path composed of feature parameter recognition, fluctuation pattern classification, cause attribution analysis, and diagnostic support system for the frequent occurrence of pressure fluctuations in system operation. The research results show that the system has clear recognition ability in high disturbance frequency bands, with a diagnostic accuracy of 80% and a stability index reduced from 0.126 to 0.078, demonstrating good regional adaptability and engineering scalability.
