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 is composed 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.
