Gravity pipeline pumping station water collection range analysis method and device

Abstract

The invention discloses a method for analyzing the collection range of a gravity pipeline pumping station, which includes such steps as modeling the data of drainage pipeline, connecting drainage pipeline to each other to obtain drainage pipeline network, carrying out topological inspection by suspension inspection and connection analysis after connection is completed, and carrying out topologicalinspection by connecting the drainage pipeline network to the gravity pipeline pumping station to obtain drainage pipeline network; analyzing the flow direction of the established drainage pipe network and marking the flow direction of the drainage pipe line with an arrow; starting from the pumping station, each branch of incoming water being tracked upstream in the direction of water flow according to the depth-first algorithm until all pipelines and pipe points at opposite junctions of water flow direction are found; carrying out spatial position analysis on the pipeline and the pipe point,respectively judging the relationship between the pipeline and the road surface, the district or the factory area; all the coordinates of the points in the result set being traversed in turn, and theouter contour being obtained by a Graham convex hull algorithm, which is the water collection range of the pumping station. Through the method, the water collection area of the backbone network can be known, and the corresponding drainage pump station of the pipeline can be quickly found.

Description

technical field [0001] The invention relates to the field of big data analysis, in particular to a method and device for analyzing the water collection range of a gravity pipeline pumping station. Background technique [0002] Urban drainage is an indispensable and important infrastructure for modern cities, a basic industry with overall and leading influence on urban economic development; it is a backbone project for urban water pollution prevention and control, urban drainage, drainage, and flood control. Urban drainage facilities are an important symbol to measure the level of a modern city and an important link to improve the investment environment of the city. [0003] At this stage, the drainage management department can only rely on historical experience or feeling to understand the water collection range of the main drainage pipe network pumping station, and cannot comprehensively analyze the underground distribution of drainage pipelines and pipeline elevation data....

Problems solved by technology

[0003] At this stage, the drainage management department can only rely on historical experience or feeling to understand the water collection range of the main drainage pipe network pumping station, and cannot comprehensively analyze the underground distribution of drainage pipelines and pipeline elevation data. It is difficult to fully grasp the water collection of pumping stations area, when the operating load of the pipeline network is large, it cannot be adjusted by dispatching pumping stations
