Pipeline Leaking Monitoring And Positioning System Research

For the airport, the security is an important guarantee. While the water security is one of the important aspects. In fact, the security of water supply for civil aviation industry is still based on human which wasted a lot of waste resources.So it’s necessary that the pipeline leakage detection technology is analyzed. the characteristics of the present situation of water supply at the civil aviation airport is researched. So, a efficient, fast, intelligent and suitable way for civil aviation airport can be found. And it will create a great environmental and lots of economic and social benefits.First, the characteristics of the pipeline and the hydraulic medium is analyzed, then the characteristics of the airport pipeline network is researched. In order to establish the model of identification of water supply pipeline leak positioning system, the hydraulic characteristics of the different condition is deeply analyzed. With the aid of the EPANETH software, the model of the water supply network based on the actual pipe network is set up. After the analysis of the existing methods,leakage identification model is set up based on support vector machines.In the model, the various factors of the pressure, water flow, frictional coefficient, the material of the pipe are considered. Specially, the parameter c,g of support vector machine, particle swarm optimization algorithm is proposed to optimize them.Eventually,by using the method of pressure gradient, the accuracy of positioning is implemented.The simulation results show that the established model of pipeline leakage is of great advantage in positioning accuracy,and it meets the requirements of water supply pipe network monitoring.
