大棚智能控制系统
【摘要】
我国南方天气炎热而漫长,为了满足人们日常生活中对蔬菜的需要而大力推广大棚蔬菜的种植。随着人们生活水平的日益增长,对蔬菜的要求也较高,蔬菜在适宜的温度下才会茁壮成长。大棚智能控制系统以AT89C51单片机为控制核心,利用数字温度模块DS18B20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。本系统由单片机小系统模块、温度采集模块、加热模块、降温模块、湿度报警模块、按键以及显示模块七个部分组成。可以通过按键设定温室的最适温度值,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大时,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,从而保证大棚内作物在最佳的温度条件下生长,提高质量和产量。

Greenhouse intelligent control system to AT89C51 control core , using digital temperature module DS18B20 temperature inside the greenhouse vegetable real-time acquisition and control , automatic temperature control greenhouse . The system consists of a small single-chip system module , temperature acquisition module, theheating module , cooling module, the buttons and the display module is composed of six parts . Can be set through the key greenhouse optimum temperature value , temperature and set temperature collected by LED digital display . When the set temperature value greater than the acquisition of temperature when heated by the heater to reach the set value ; contrary, the cooling fan is turned on to rapidly achieve the cooling effect . With this system, the temperature inside the greenhouse vegetable effective , reliable detection and control, in order to ensure the crop canopy temperature under optimum conditions for growth , improve quality and yield.
