Problems solved by technology

At present, most pipe network systems are based on the analysis and display of two-dimensional planes, that is, when the monitoring equipment detects a pipe burst accident, it will correspond the actual burst position to the two-dimensional pipe network display map, so as to analyze its adjacent controllable However, this two-dimensional analysis method cannot intuitively reflect the information of the underground pipe network, and errors often occur in the pipe burst analysis, so that the position of the controllable valve cannot be judged in time, so it cannot be timely Close the valve, the repair efficiency will not be improved

Embodiment Construction

[0022] The specific embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings:

[0023] Urban underground pipeline network usually includes water supply pipeline network, gas pipeline network, heating pipeline network, drainage pipeline network, electric pipeline network, sewage pipeline network and telecommunication pipeline network, etc. Each type of pipeline network consists of pipeline sections and auxiliary facilities. Tree-like, ring-like, or radiating, forming a system such as figure 1 The three-dimensional scene of the urban pipe network is first created under the GIS system. When the external system detects that a pipe burst occurs, the position of the pipe burst is determined in the GIS three-dimensional scene, and then the map is used according to the position of the pipe burst. On the depth-first search (Depth-First Search, DFS) in the search algorithm to determine the position of the valve that can...

Abstract

The invention relates to a method for analyzing a cartridge igniter of a city integrated pipe network in a three-dimensional visual environment, comprising the following steps: (a) establishing a three-dimensional visual scene of city underground pipe network in a geographical information system; (b) positioning a cartridge igniter accident in the three-dimensional visual scene of city underground pipe network; (c) searching out controllable valves near cartridge igniter and displaying by a distinguishing mode; (d) confirming the type of cartridge igniter and correspondingly displaying cartridge igniter effect. The method for analyzing the cartridge igniter is the method for analyzing cartridge igniter of city integrated pipe network in three-dimensional visual environment based on GIS system, and the method for analyzing the cartridge igniter can be packaged in a monitoring system in related managing part of the city pipeline; by inputting cartridge igniter position to the monitoring system, the management department can obtain the information that which valves are closed, so the convenient and quick pipe maintenance work can be ensured.

Description

technical field [0001] The invention relates to a pipe burst analysis method of an urban underground pipe network. Background technique [0002] Various types of underground pipe networks in cities are an important part of urban infrastructure. They are like nerves and blood vessels in the human body. They are responsible for the work of transmitting information and energy day and night. They are the material basis for the survival and development of cities. The lifeline of the city. A good investment environment formed by good infrastructure and perfect urban functions is the guarantee for accelerating economic development and accelerating the process of modernization. [0003] Pipe burst is a kind of pipe network failure that is extremely harmful to the pipe network, and it has the characteristics of sudden and destructive. Once a pipe burst occurs, such as a burst pipe in the water supply network, it will not only waste water resources, bring economic losses to water su...
