ABSTRACT:
A method of detecting the location of a failure (e.g., a sudden leak) in a fluid pipeline network, which can be suitably used for estimation of the location of a failure in a water pipeline network, includes the steps of periodically measuring a flow rate or fluid pressure with sensors arranged at a plurality of measuring points along a pipeline in a water pipeline network; comparing a latest measured amount and a previous measured amount at each measuring point to determine if an amount of change at an arbitrary point has exceeded a predetermined value; and calculating a position at which an amount of change becomes maximum, the position being calculated from the magnitudes of the amounts of changes in respective measured values at the time of the detection. The pipeline network may be a water supply and distribution pipeline network which includes a trunk pipeline and branch pipelines.
