specific Embodiment approach

[0084] Specific implementation method, get N=149, M=24, promptly the quantity of wheel irrigation branch pipe is 149, and the quantity of wheel irrigation group is 24, then has 24 1 +24 2 +24 3 +...+24 (149-24) It is almost impossible to calculate such a distribution plan by computer enumeration method; it takes 1 to 2 days to get a feasible plan by using the manual experience method combined with an Excel table, and it is not necessarily the optimal plan; The wheel irrigation group division method of the present invention only needs a few seconds to obtain the optimal solution, that is, the best plan for wheel irrigation group division through program implementation.

[0085] The specific calculation results are shown in Table 1 below:

Abstract

The invention relates to a method for dividing irrigation-wheel groups, which comprises the following steps: step 1: establishing a mathematical model for dividing irrigation-wheel groups; step 2: distributing all irrigation-wheel branch pipes so that the mathematical model established in step 1 The function is the smallest, that is, the head and flow of each wheel irrigation group reach a comprehensive balance. The beneficial effects of the present invention are: adopting the method of combining the bubble sorting algorithm and the greedy algorithm to deal with the problem of the comprehensive balance of flow and head of the wheel irrigation group, improve the optimization level of the pipe network, shorten the division time of the wheel irrigation group in the design of the pipe network, and improve Network design efficiency.

Description

technical field [0001] The invention relates to the technical fields of agriculture and garden irrigation, in particular to a method for dividing irrigation wheel groups. Background technique [0002] The design of water-saving irrigation (mainly sprinkler and drip irrigation) mainly includes two stages: pipe network layout and wheel irrigation scheme division. Generally, the two are complementary to each other. However, considering the convenience of construction and the specifications of pipelines, in recent years, many places The pipe network adopts a fixed pattern, so the current design of water-saving irrigation mainly lies in the division of rotational irrigation schemes. The realization of wheel irrigation is mainly to control the opening and closing of the valves at the entrance of ground branch pipes or spraying branch pipes, so as to achieve the purpose of irrigation in turn for each branch pipe of the system, so as to disperse the flow and save project investment ...
