FIELD: fluid leak detection systems.
SUBSTANCE: invention relates to a fluid leak detection system for detecting fluid leaks in buildings. A fluid leakage detection system comprising: a plurality of sensors provided in the building, which respectively detect detection target values at their mounting positions; a fluid leak detection device that detects a fluid leak in a building by a leak state estimation algorithm used to estimate a fluid leak state in a building based on the detection target values detected by the plurality of sensors; and a teaching unit that trains a leak state estimation algorithm, the fluid leak detecting device comprises: an actual measured value acquiring unit that obtains detection target value values detected by the plurality of sensors; and a leakage state estimating unit that estimates the leakage state of a fluid in a building by an algorithm for estimating a leak condition based on distributions of detection target value values obtained by the actual measured value obtaining unit, the teaching unit comprises: a teaching unit that trains an algorithm for evaluating a leak state by means of machine teaching unit, as training data, the values of the detection target values respectively detected by a plurality of sensors during a fluid leak from a predetermined position of the building; a structural data storage unit that stores structural data of a building; and a 3D flow simulator that simulates the behavior of a fluid in a building during fluid leakage from a predetermined position of a building by performing a 3D flow simulation based on the structural data of the building stored in the structural data storage unit, the teaching unit teaching the leak state estimation algorithm by machine learning, further using, as training data, the detection target values calculated based on the result of the 3D flow simulation performed by the 3D flow simulator.
EFFECT: accurate detection of fluid leakage conditions in buildings.
