Leakage pattern monitoring method of CEP based water supply block system

Abstract

The water supply block system is used for detecting a leakage by grouping the drainpipe network in large, medium and small blocks, and managing the maintenance of suitable fluid pressure and flow and measuring the flow of each block. As the block system of water supply was introduced, an enormous amount of flow data stream is created from the block, and the necessity to process this in real time has ensued. To resolve this necessity, this thesis reviews the method for detecting a leakage in the block in real time, using CEP (Complex Event Processing). CEP processes the events arising from multiple sources in real time, and derives a significant event. CEP is used to detect the occurrence of a leakage within the block, while observing the flow data obtained from customers in small blocks as well as the flow data of small block flow meters. Furthermore, this thesis presents the visualization tools for displaying the leakage results detected from CEP on the map.
