Problems solved by technology
[0005] The main purpose of this application is to provide a valve dynamic flow management method and device to solve the problems in the irrigation system caused by group control irrigation valves in the related art to ensure that the sum of the rated flow rates of the opened irrigation valves is close to or equal to the flow rate of the water source. The operation process is limited by the grouping situation, and it is impossible to flexibly control the operation of different irrigation valves

The application discloses a valve dynamic flow management method. The method includes determining the valve to be opened; determining the pipeline to be calculated according to the valve to be opened; judging whether the current remaining flow of the pipeline to be calculated is greater than the rated flow of the valve to be opened according to a preset sequence; If the current remaining flow of the calculation pipeline is greater than the rated flow of the valve to be opened, the valve to be opened is opened. This application solves the problem of group control irrigation valves in the related art to ensure that the sum of the rated flow rates of the opened irrigation valves is close to or equal to the flow rate of the water source. As a result, the operation process of the irrigation system is limited by the grouping situation, and it is impossible to flexibly control the operation of different irrigation valves. technical problems.
Description
technical field [0001] The present application relates to the field of crop irrigation, in particular to a valve dynamic flow management method and device. Background technique [0002] The growth status of crops is determined by the irrigation effect of the irrigation system. The irrigation system consists of a water source, a first-level main pipe, a second-level main pipe...the N-1st main pipe, the Nth-level main pipe, a sub-main pipe, and a set on the sub-main pipe to control the flow of water out of the irrigation pipeline. The irrigation valve is composed of the irrigation valve on the branch pipe to control the flow of water out of the irrigation pipeline, and then to irrigate the crops. The pipeline topological relationship records the affiliation and maximum flow of water sources, pipelines and irrigation valves in the irrigation system. figure 1 It is a pipeline topology diagram of an irrigation system, wherein the irrigation system includes a water source, a fir...
