摘要
针对舰艇消防管网控制实时性要求高、管网拓扑结构复杂、漏损探测定位难等特点,提出基于相关分析法的管网漏损探测和定位方法。介绍了相关分析法,并对相关分析法中的灵敏度矩阵计算方法进行了研究,通过寻找相关函数中取得最大值的节点确定管网系统中的漏损节点。进行了数值仿真,结果表明该方法是一种有效的漏损探测、定位方法。
Aiming at the characteristic of the firefighting piping network requiring high real-time, network topology complexity and difficulty to locate the leakage pipe, leakage detection and localization methodology for firefighting piping network based on correlation method was proposed. Basic principle of the correlation method was introduced and sensitivity matrix was determined, the leakage pipe gets the largest correlation function, then the leakage pipe can be determined..At last, the numerical simulation was carried out and the simulation result proves its efficiency for leakage detection and localization.
