多源感知高效循环智能控制设施大棚架构与实现

     

摘要

以提高作物经济效益、减少资源消耗、增加农业循环利用为目标,提出一种多源感知高效循环设施大棚智能控制及农业专家系统。利用太阳能加热相变储热材料增加棚温;通过特殊通风窗设计增大空气对流面积降低棚温,减少高能耗设备的启用;阴阳棚混合种植实现农业循环利用;采用多源感知提高控制精准,采用动态权值融合算法提高数据融合精度,可通过计算机、手机实时监控。该农业专家系统控制策略结合作物生长模型、温室控制模型与能耗模型3种模型,提出根据大棚作物光合作用速率的多因素节能优化控制方法。根据计算控制增加的经济效益与付出能耗费用的差值最大,得出最优控制策略输出,以促进作物光合作用产生高收益,并减少温室控制成本。整套监控系统已试运行于徐州现代农业实验示范基地。%In order to reduce the energy consumption and labor costs in the process of crop production in greenhouse , and to increase the agricultural recycling effect , an efficient recycling greenhouse design system was proposed .In or-der to reduce the use of high energy consumption equipment , the solar heating materials were used for thermal storage to increase temperature in the greenhouse , and the special ventilation window design was applied to increase the air convection area and reduce temperature in the greenhouse .The agricultural recycling was achieved by combining light with shade solar greenhouse , which could be controlled by computers and mobile phones via multi-source per-ception and dynamic weighting fusion algorithm to improve control and fusion accuracy .This agricultural expert sys-tem control strategy was integrated with 3 models, i.e.crops growth model, greenhouse control model and energy consumption model , and the multiple factors and energy saving optimization control method was put forward according to crop photosynthesis rate in greenhouse .In view of the difference between the economic benefit and the cost of en-ergy consumption , the optimal control strategy was obtained , which could increase yield and reduce the cost of green-house control .Up to now, the whole set of monitoring system has been tested in Xuzhou modern agricultural experi -ment demonstration base .
