论文摘要
使用传感器检测水分分配网络（WDN）的泄漏已经对水资源的有效管理至关重要。使用此数据的泄漏检测方法取决于获得数据的正确性。但是，在实践中通常会违反此假设。因此，传感器故障下的泄漏检测是一个实际重要性的问题。这涉及通过传感器之间的拓扑关系利用可用的冗余，这与传感器中同时可检测性和过程故障的同时可检测性问题有关。因此，本文的目的是i）将WDN建模为包含系统和传感器故障的图形ii）为该图提供理论的联合可检测性结果，iii）将这些结果应用于传感器故障条件下在农村WDN发出的真实数据下泄漏识别的情况。
Detecting leaks in Water Distribution Networks (WDN) using sensors has become crucial towards an efficient management of water resources. The leak detection methods that use this data rely on the correctness of the acquired data. However, this assumption is often violated in practice. Consequently, leak detection under sensor faults is a problem of practical importance. This relates to the more general problem of simultaneous detectability in sensor and process faults for a class of systems modelled as a network, by exploiting the redundancies available through the topological relationship between the sensors. This paper hence aims at i) modeling WDN as graphs containing both systems and sensors faults ii) providing theoretical joint detectability results for such graphs and iii) applying these results to the scenario of leak identification under sensor faults conditions on real data issued from a rural WDN.
