基于无线传感网的温室作物根层水肥智能环境调控系统

Intelligent Control System of Root Layer Water-Fertilization in Greenhouse Based on Wireless Sensor Network

基于我国水资源短缺和超量使用化肥的严重现状,为达到科学用水施肥的目的,通过采集土壤温湿度、空气温湿度、光照辐射量等信息,并结合作物生长信息,经作物种植专家系统分析后,决策所需灌溉水肥量,利用电磁阀、管道、纳米微孔管和作物根层负压等来自动调解控制植物根部的水肥补给,实现作物根层微灌的自动化,优化植物的生长环境,提高水肥利用率。针对我国现阶段农业偏远、易变、分散的特点,提出了基于ZigBee的无线传感器技术、ARM嵌入式技术、Internet网络及现代信息管理发布系统的温室现场信息采集监控系统设计方案。

Based on the situation that our nation is seriously lack of water and excessive use of fertilizers,for the object of saving water and rational fertilization,by collecting temperature and humidity in soil,temperature and humidity in air,light radiation,according to crop information analysis system of plant cultivation expert,to make decision required amount of irrigation water and fertilizers.Solenoid valves,pipes,nano-porous tube and the negative pressure of the root layer automatically adjust the control of the water and fertilizer supply,to Automate root layer of micro-irrigation,optimize the growth of plant growth environment,improve water use efficiency.According to the characteristics of farness,disperse and inconstancy of agriculture in China,the design of greenhouse information collection monitoring and control system is presented based on the technology of ZigBee wireless sensor technology,the ARM embedded technology,the Internet network and modern information management.A variety of information collection,management,analysis and dissemination to provide new ideas,new means for the greenhouse monitoring system.
