摘要
针对在传统日照温室大棚管理中存在收放保温卷帘和通风劳动强度大等问题,设计了自动卷帘与智能通风控制系统,系统主要由环境监测节点、执行节点和控制决策中心组成。节点在控制器C8051F020平台上开发而成,实现了对棚内温湿度、CO2浓度和光照度的监测,并通过无线模块n RF905上传到控制决策中心,根据作物生长专家知识库对风机和自动卷帘机进行控制,达到调节棚内环境参数的目的。结果表明,该系统能准确测量棚内的环境参数,并通过控制风机对温湿度进行自动调节,为作物的高产创造了条件,实现了温室大棚种植的精准化和智能化管理。
For the intensity of work of insulation shutter and ventilation in the sunlight greenhouse management,an automatic rolling machine and intelligent ventilation control system which is composed of environment monitoring nodes,action node and the control decision center is designed. The nodes are developed on the platform of Processor C8051F020,which can monitor the temperature,humidity and CO2 concentration,and upload to the control decision center by the wireless module nRF905,then control the fan or autoatic rolling machine to adjust the environment parameters in the greenhouse according to the crop exper knowledge base.The experiment results on the fruit setting period tomato show that the designed system can accurately measure the environment parameters in the greenhous,and automaticly adjust the temperature and humidity by controlling the fan work-ing condition,which can improve the crop yield and realize the precise and intelligent management of the greenhouse planting.
