基于单片机温室大棚温度监控系统的设计
摘要:本系统以AT89C51单片机为控制核心,利用温度传感器AD590
对蔬菜大棚内的温度进行实时采集与控制,实现温室温度的自动控
制。本系统以单片机小系统模块,温度采集模块,加热模块,降温模
块,按键以及显示模块六个部分组成。可以通过按键设定温室的温度
值,采集的温度和设定的温度通过LED数码管显示。当所设定的温度
值比采集的温度值打时,通过加热器加热,以达到设定值;反之,开
启降温风扇,以快速达到降温效果。通过该系统对蔬菜大棚内的温度
进行有效可靠地检测与控制。从而保证大棚内的作物在最佳温度条下
生长,提高质量和产量。. 关键词:单片机温室大棚温度控制
Abstract: the system to AT89C51 SCM as control core, real-time
data acquisitionand control using the temperature sensor AD590
temperature of the greenhouse, realize the automatic control of the
greenhouse temperature. The system posed of single chip
microprocessor system module, the temperature acquisition
module, a heating module, temperature module,keyboard and
display module six parts. You can set the key
greenhousetemperature value, the collection of temperature and
set temperature by LED digital tube display. When the set
temperature value than the acquisition of temperature is high, through heating, in order to reach the set value; otherwise,open the cooling fan, to achieve cooling effect. Through the system, effective,reliable detection and control of the greenhouse temperature. In order to ensurethe greenhouse crop at the optimum temperature of growth, improve quality andyield.
Keywords: single chip puter, greenhouse, temperature control
