Embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described in further detail:
Urban Buried Pipeline Network generally includes water supply network, gas ductwork, heating network, drainage pipeline networks, the electric power pipe network, blowdown pipe network and telecommunications pipe network etc., each class pipe network all is made up of line sections and affiliated facility, be tree-shaped, ring-type or radial, form a system, as shown in Figure 1, at first under generalized information system, create described urban pipe network three-dimensional scenic, when external system has detected the booster generation, in this GIS three-dimensional scenic, determine the position of booster, utilize depth-first search (Depth-First Search in the graph theory searching algorithm according to the position of this booster then, DFS) determine the position that can control the nearest valve of this leakage line, the basic thought of described depth-first search is:
To be example from vertex v, at first v is labeled as the summit that has arrived, select a summit u with the no show still of v adjacency then, if such u does not exist, search is ended; Suppose that such u exists, and then begins a new DFS again from u.When the search that begins from u finishes, select the summit of the no show still of another one and v adjacency again, if such summit does not exist, then search is ended; And if have such summit, begin DFS again from this summit, so circulation is gone down.
So in the present embodiment, the search procedure near the controllable valve the booster point is as follows:
Referring to Fig. 1, suppose that figure mid point A, F, G, C point are controllable valve, the P point is the booster point, and other points are common physical prospecting period, and then the concrete steps of booster pass valve are:
From booster point P, the pipe point J of selection and P adjacency judges whether the J point is controllable valve;
Knowing that by known conditions the J point is not a controllable valve, is starting point with the J point then, the A point of selection and J adjacency, thus filter out the A point for closing valve position;
Continuing with the J point equally is starting point, judges whether G, E point satisfies condition, and filters out the G point for closing valve position, all screens until all pipe points that are connected with the J point to finish;
Jump to initial booster point P, select reverse adjacent pipe point C, repeat above step.
