Embodiment

[0176] The selected embodiment of the present invention is the data of the irrigation area of ​​the 150 regiments, one battalion and two branch canals of the Xinjiang Mosuowan irrigation area.

[0177] Mosuowan Irrigation District is located in the center of the Economic Development Zone on the northern slope of Tianshan Mountain. The irrigation district governs four large-scale farming and animal husbandry farms. The selected 1st Battalion and 2nd Branch Canal of the 150th Regiment is located upstream of the 3rd Main Canal, with a total length of 2600m and a control area of ​​256.33hm 2 , to control the two water units of the first company and the third company. The branch canal design flow Q is 0.65m 3 / s, the channel water utilization coefficient η is 0.975, and there are 12 bucket canals below, that is, the number N of lower-level channels is 12, and the irrigation cycle is T 0 is 144h, and the data information of each bucket canal is shown in Table 1.

Abstract

The invention belongs to the technical field of intelligent agriculture and particularly relates to a particle swarm algorithm-based canal system optimization water distribution method. The method comprises the steps of 1, establishing a target function according to upstream canal capacity, a canal water utilization coefficient, a downstream canal quantity and downstream canal capacity, and determining a rotational irrigation group number range, and a total particle number of a particle swarm and a maximum iterative frequency required for running a particle swarm algorithm; 2, generating the particle swarm in a feasible region by utilizing the particle swarm algorithm; 3, judging whether particles in the generated particle swarm meet constraint conditions or not; 4, recording the positions of all the particles meeting the constraint conditions; 5, calculating fitness values of the particles; and 6, judging whether the particle swarm algorithm reaches the maximum iterative frequency or not, and if the maximum iterative frequency is reached, outputting an optimization result, or otherwise, updating speed and position information of all the particles and performing the steps 5 and 6 again. The method is suitable for different types, different regions and different irrigation areas, and is high in practicality and universality.

Description

technical field [0001] The invention belongs to the technical field of intelligent agriculture, and in particular relates to a method for optimizing water distribution of a canal system based on a particle swarm algorithm. Background technique [0002] As a large agricultural country, my country's agricultural water consumption has accounted for 72% of the country's total water consumption, most of which are used for irrigation, but the utilization efficiency of irrigation water is extremely low, and the utilization rate of irrigation water resources in many irrigation areas is only 40%. It is inconsistent with my country's current efforts to build a sustainable and economical society. Therefore, under the background of the increasingly serious contradiction between the supply and demand of irrigation water resources, the importance and necessity of the rational and optimal allocation of irrigation water resources, which occupy an important position in agricultural production...
