Embodiment 1
[0027] A Gojs-based method for making generalized diagrams of joint flood control dispatching schemes for reservoir groups, such as figure 1 shown, including the following process:
[0028] 1) Generalize the natural elements and engineering in the watershed: generalize the natural and social elements and reservoir engineering in the watershed into watershed units, interval units, confluence point units, reservoir units, protected object units, and river section units. Six types of units; for natural watersheds that directly flow into the reservoir, they are generalized as watershed units; for upstream unnatural watersheds, but watersheds with reservoir engineering, they are generalized as interval units from the reservoir section to the outlet of the watershed; for tributaries in the water system, The nodes where the main streams intersect are generalized as confluence point units; for reservoir projects with flood control capacity in the watershed, they are generalized a...

The invention discloses a Gojs-based reservoir group flood control joint scheduling scheme generalization graph making method. The method comprises the steps of generalizing natural elements and projects in a drainage basin, generating a generalization icon and a drawing space based on Gojs, dragging and connecting generalization units based on a drainage basin water system topological relation to form a generalization graph, setting attributes of the generalization units and storing the generalization graph as a json file. The method does not need to depend on a geographic information system, can quickly generate a joint scheduling generalization graph according to a controlled reservoir project and a main protection object concerned by a user in a drainage basin, is convenient to store and transmit, can be connected with a joint scheduling model and a system, provides sufficient input information for the model, and provides visual display content for the system.
Description
technical field [0001] The invention relates to the field of flood control dispatching of reservoirs, in particular to a method for making a generalized diagram of a flood control joint dispatching scheme of a reservoir group based on a front-end interactive graph drawing library Gojs. This method does not need to rely on the geographic information system, and can quickly generate a generalized map of joint scheduling according to the controlled reservoir projects and main protection objects in the watershed that users are concerned about. Background technique [0002] my country has carried out the construction of large-scale flood control projects based on dikes and reservoirs, and the frequent flood disasters have been initially controlled, and the flood control standards and overall flood control capabilities of major rivers have been further improved. However, in recent years, affected by climate change, extreme rainfall events have increased, and the pressure on the fl...
