Study On Pipe Explosion Early Warnling Model Of Urban Water Supply Network

Water in people life and production activities occupies an important position. Water supply network is indispensable to the city infrastructure, and also one of the urban lifeline project is an important part. Water supply network shoulder will comply with the requirements of the water quality of water transport to each user safely task, its importance is self-evident. Once the pipe network into accidents, it will give people’s production and life inconvenient. In recent years, due to the acceleration of urbanization, and expansion of the size of the city, urban water supply system also gradually expands, the water supply system of distribution network also is complicated, pipe length increased; At the same time, the city water supply network aging increasingly heavier. These are tempted to the city water supply network pipe explosion accidents and frequent. Over the years, pipe network leakage has been the impact of water company the biggest problem of poor sales., reduce pipe leakage water supply enterprises has become one of the problem to be solved. In the pipeline leakage accident several pipe explosion accidents and most serious, it happens suddenly and water leakage is larger, easy to peripheral residents living environment and the social public opinion cause bad effect. Therefore, how to effectively solve the urban water supply network of pipe explosion problem has already become the domestic and foreign various problems facing water department, and the key to solve this problem is to pipe explosion mechanism, pipe explosion fully understand the theory and practical establish pipe explosion forecast model. And for the pipe explosion, especially in China, mainly with the traditional descriptive statistical analysis is given priority to, general use through the material of pipes, Tube use fixed number of year, the time of builtin, season and static factors on the hidden trouble of the pipe tube blasting are analyzed, and with no pressure, flow and dynamic data analysis, simulation. This paper considers synthetically multiple factors and combined with the SCADA system for urban water supply network dynamic data by using fuzzy theory analysis, based on the research of the platform of CAD urban water supply network pipe explosion early warning model, and strive to achieve the computer to water supply network pipe explosion accidents of monitoring and warning.The specific practices for:(1) to pipe explosion the cause of the accident and its law analysis;(2) according to the theoretical analysis build pipeline network factors model, combine the SCADA pressure measuring point get more accurate pressure value freedom;(3) will history pipe explosion as the benchmark state and freedom data pressure comparison and analysis, and by using fuzzy theory further construct city pipe tube blasting of the early warning of the preliminary model;(4) use actual data validation and correct early warning model, combine with CAD, computer language for design visualization, urban water supply network pipe explosion early warning system to provide the theory basis.
