specific Embodiment approach 1

[0039] Specific implementation mode one: refer to figure 1 Specifically explaining this embodiment, the automatic combing method of the city "factory network river" topological relationship described in this embodiment includes the following steps:

[0040] Step 1: Read pipe network data, which includes pipe section data and node data.

[0041] Pipe section data includes: pipe section name, pipe section number, pipe section category, pipe section nature, whether to participate in combing, starting point x, starting point y, starting point category, starting point inspection well invert elevation, starting point pipe section offset, end point x, end point y, end point category, end point Check the fields such as the elevation of the well invert, the offset of the end pipe section, the pipe diameter, the cross section of the pipe section, and the error and warning reminders. Wherein, the starting point x and the starting point y are the x-axis coordinate value and the y-axis co...

[0073] Combined with the actual situation, this implementation uses the python language for programming and packages it as an independent application program. The window interface displays reserved variables and operation progress results, and the specific traversal process is carried out in the background.

[0074] The data source of this embodiment is the urban "factory network and river" database formed by the basic information survey of the city "factory network and river", including pipe section data and node data. Initially, 9300 lines of pipe section data and 9410 lines of node data were read.

[0075] According to the "principal component of the pipe section to filter the critical pipe diameter" input by the user, delete the pipe section data smaller than the critical pipe diameter in the input pipe section data. In this embodiment, the deleted pipe section data is 6496 lines.

[0076] Match the node data with the pipe segment data, and delete the unmatched node data. I...

Abstract

The invention discloses an automatic sorting method for urban plant-network-river topological relations, and relates to the technical field of environmental system simulation and prediction. The objective of the invention is to solve the problems of long time consumption, low efficiency and high error rate caused by manual sorting of a plant network river topological relation in the prior art. According to the invention, the complex connection relationship of the urbanplant-network-riverwater system is abstracted into a two-dimensional point-line topological structure, data rationality check is realized by using a depth-first traversal algorithm, topological structure check and extension are achieved by using a breadth-first traversal algorithm, and efficient automation of the conversion process is achieved by using an intelligent automation technology. According to the invention, automatic construction of a flow direction relationship of a pipe network-sewage plant-river discharge port-river is achieved, flow direction errors, pipeline breakpoints, river discharge port omission and the like are automatically identified and corrected, and a hydrodynamic path of an urban'plant network river 'is intelligently penetrated, so that modeling and operation management services are provided for the urban'plant-network-river'.

Description

technical field [0001] The invention belongs to the technical field of environmental system simulation prediction. Background technique [0002] The urban "factory network river" water system consisting of sewage treatment plants, pipe networks, and rivers is responsible for collecting, transporting, and treating rainwater and sewage generated in urban production and living processes, which significantly affects the quality of urban water environment and water ecological security. Establishing a hydraulic and water quality model of the urban "factory-network river" water system can simulate and evaluate the "factory-network river" drainage, disaster reduction, source control and sewage interception capabilities, and provide scientific guidance for the operation and management of the "factory-network river", which is of great significance. [0003] However, the prerequisite for establishing the hydraulic water quality model of the "factory network river" water system is to ac...
