针对舰艇管网控制实时性要求高、管网拓扑结构复杂等特点,提出基于模糊理论的分布式管网漏损探测和定位方法。介绍模糊理论的基本原理,确定隶属度函数,提出管网系统的故障隶属度和漏损指数作为管网是否发生漏损的特征参数,判断管网系统是否发生漏损,并根据漏损点附近漏损指数最大的特点,通过找出各个节点或者管段的最大漏损指数实现管网漏损点定位。最后对本文所提方法进行数值仿真,仿真结果表明该方法是一种有效的漏损探测、定位方法。
針對艦艇管網控製實時性要求高、管網拓撲結構複雜等特點,提齣基于模糊理論的分佈式管網漏損探測和定位方法。介紹模糊理論的基本原理,確定隸屬度函數,提齣管網繫統的故障隸屬度和漏損指數作為管網是否髮生漏損的特徵參數,判斷管網繫統是否髮生漏損,併根據漏損點附近漏損指數最大的特點,通過找齣各箇節點或者管段的最大漏損指數實現管網漏損點定位。最後對本文所提方法進行數值倣真,倣真結果錶明該方法是一種有效的漏損探測、定位方法。

Aiming at the characteristic of the ship piping network requires high real-time and its complexity, distributed leakage detection and localization methodology for ship piping network based on fuzzy theory is obtained. Basic principle of the fuzzy theory is introduced and membership function is determined, then piping network′s degree of failure membership and index of leakage propensity is proposed, they can reflex whether the piping network occurs leakage, according to the characteristic of the maximum leakage index located near the leakage point, so leakage localization can be realized by finding the maximum leakage index. At last, the numerical simulation is carried out and the simulation result proves its efficiency for leakage detection and localization.
