摘　　要：供水管网系统是城市重要的基础设施之一,负担着输水供水的重要任务,但目前爆管事故频发,严重影响了人们的生产、生活。针对这一问题,首先采用小波分析处理管网压力信号,根据处理后的高频信息判断出明显的故障点,对于疑似存在的故障点利用拉依达准则对处理后的高频信息进行处理从而找出剩余的故障点。采用实例对所提出的方法进行验证,结果表明,将该方法用于供水管网爆管信号检测可行。Water distribution system is one of the important infrastructure of the city which shoulders the responsibility of water delivery and water supply. However, recently pipe burst occurs frequently, which seriously affect people＇s living and production. To solve this problem, firstly, use wavelet analysis to separate the pressure signal and according to the high frequency information found the obvious fault point, then use Pauta criterion to analysis the high frequency information so as to find out the rest of the fault point. An example is applied to illustrate the application of the proposed method , and the obtained results show that the method is feasible.
