摘要:: 随着智能信息化的发展,智慧管网在人们的日常生活和城市的发展中的需求越来越大,然而智慧管网算法问题一直是一个难题。针对管网爆管点查找模糊、流量监测数据精度不高和管网成本评估分析困难等问题,根据流向分析与缓冲分析结合的思想, 设计一种基于流向的管网爆管分析算法,采用管线管网漏损率和多因素的综合资产评估方法设计了管网评估算法,采用面积比流量、沿线水头损失、水力等效原则和管网水力平差等设计了管网水力计算算法。最后通过乐山市市中区管网数据进行了实验分析,有效地实现了智能化的流量监控、预警提示、爆管点分析、智能规划维修路线以及管网成本评估等功能,达到了智慧管网算法的基本需求。

Abstract:: With the development of intelligent informatization,the demand of intelligent pipe network in people’s daily life and urban development is increasing. However,the algorithm of intelligent pipe network has always been a difficult problem. In view of the problems such as fuzzy finding of pipe network burst point,low accuracy of flow tube blasting network monitoring data and difficulty in cost assessment and analysis of pipe network,a flow-based pipe burst analysis algorithm is designed according to the idea of combining flow analysis with buffer analysis. A network evaluation algorithm is designed by comprehensive appraisal method with pipeline pipe network leakage rate and multi-factor, and a hydraulic calculation algorithm is designed by the area ratio along the flow,head loss,poor hydraulic equivalent principle and the hydraulic leveling. Finally,through the experimental analysis of pipe network data in Shizhong district of Leshan city,the functions of intelligent flow monitoring,early warning,analysis of burst point, intelligent planning and maintenance route,and pipe network cost assessment are effectively realized to meet the basic requirements of the intelligent pipe network algorithms.
