摘　　要：以喷灌系统为研究对象,通过分析智能喷灌系统的工作原理和系统组成,建立起一种利用太阳能实现控制系统能量供给的大面积智能喷灌系统。根据智能喷灌系统的布置形式和原则,结合喷灌系统的工作参数,建立以喷灌系统造价为目标的喷灌系统参数优化模型,对参数优化模型进行求解,并与未进行优化的喷灌系统进行对比,结果表明:优化后的喷灌系统管道流量增加,水头损失降低,系统造价与优化前相比明显降低。在现有的喷灌系统控制经济技术条件下,通过系统优化的方法,使喷灌系统的多方面指标达到最优化,确保喷灌系统的运行过程可靠性高,从而为后期喷灌系统设计、施工及系统运行提供理论依据。In this paper,the sprinkler system is taken as the research object.By analyzing the working principle and system composition of the intelligent sprinkler system,a large area intelligent sprinkler system is established,which uses solar energy to realize the energy supply of the control system.According to the layout form and layout principle of the intelligent sprinkler system,combined with the relevant working parameters of the sprinkler system,a sprinkler system with the cost as the goal is established The optimization model of irrigation system parameters is solved,and compared with the sprinkler system without optimization.After optimization,the pipeline flow of sprinkler system increases,the head loss decreases,and the system cost is significantly lower than before optimization.Under the existing economic and technical conditions of sprinkler system control,through the method of system optimization,the various indexes of sprinkler system are optimized to ensure the high reliability of the operation process of sprinkler system and provide theoretical basis for the design,construction and operation of sprinkler system in the later stage.
