Urban area drainage basin intelligent connected draining and connected dispatching method

Abstract

The invention discloses an urban area drainage basin intelligent connected draining and connected dispatching method. The method comprises the steps of 1, monitoring the last reach water level for each urban area drainage dispatching sluice gate station; 2, when the last reach water level of any drainage dispatching sluice gate station is raised to be higher than a warning value or it is predictedthat the last reach water level is about to reach the warning value within 4 hours, starting a sluice pump of the drainage dispatching sluice gate station; 3, when the last reach water level of any drainage dispatching sluice gate station is reduced to be lower than the warning value or when a sluice pump of an upstream dispatching sluice gate station adjacent to the dispatching sluice gate station is in the closed state and the last reach water level of the drainage dispatching sluice gate station is lower than the warning value, closing the sluice pump of the drainage dispatching sluice gate station. By means of the urban area drainage basin intelligent connected draining and connected dispatching method, the influence of sluicing on the next drainage basin section is considered in advance, and it is prevented that urban floods are caused when the next drainage basin section is not sluiced timely.

Description

technical field [0001] The invention relates to the technical field of urban flood control dispatching, in particular to an intelligent row and joint dispatching method for urban watersheds. Background technique [0002] At present, in terms of urban flood control and drainage, when the housing and construction department dispatches the drainage of urban watersheds, most cities mainly rely on manual experience dispatching, often needing to refer to the important gate pump opening and closing information of small watersheds in each urban area , water level monitoring information, video monitoring information, and rainfall live forecast information provided by the meteorological department, etc., and then dispatch according to the usual experience. In this way, there is often a single consideration in the scheduling process. For example, when heavy rainfall hits an urban area and the water level of a small watershed section exceeds the warning water level, the person in charge...

Problems solved by technology

In this way, there is often a single consideration in the scheduling process. For example, when heavy rainfall hits an urban area and the water level of a small watershed section exceeds the warning water level, the person in charge of that section will open the sluice gate to let the water drain to the next watershed section. It is rare to think about the situation of the next section of the watershed after the drainage of this section of the watershed, especially the small urban watersheds are intricate, and it is difficult to grasp the correlation between the respective watershed sections. They often think that there will be no flood risk according to the watershed conditions, and it will also be due to the drainage scheduling method. Inappropriate, causing urban floods or seawater topping (coastal cities)

[0003] The method of relying on human experience for urban watershed dispatching requires very high ability of decision makers, and also bears certain risks, and the degree of refinement cannot be guaranteed. Most of the time, water is directly discharged to prevent urban floods, causing extremely Large waste of water resources is extremely detrimental to maintaining the production safety of urban water resources; it is also possible that due to mistakes in decision-making, water from sudden rainstorms may not be discharged in time, resulting in a series of floods in relevant urban watersheds Chain reaction, causing losses to people's lives and property
