This thesis mainly elaborated based on AT89C51 tomatoes canopy temperature and humidity control system design principle, main circuit design and software design, etc. This system USES AT89C51 single chip microcomputer as controller, SHT10 as temperature and humidity data acquisition system, may to the actuator directives realize trellis temperature and humidity parameters adjustment, has the upper and lower level computer directly set temperature range, temperature and humidity real-time display, and other functions. PC using Delphi software to compile, user friendly interface, easy operation, can according to shed tomato growth situation blazoned with simple, direct simulations of crop growth, thus easy to draw the most suitable for crop growth of temperature and humidity value.
摘要
随着大棚技术的普及,温室大棚数量不断增多,对于蔬菜大棚来说,最重要的一个管理因素是温湿度控制。温湿度太低,蔬菜就会被冻死或则停止生长,所以要将温湿度始终控制在适合蔬菜生长的范围内。传统的温度控制是在温室大棚内部悬挂温度计,工人依据读取的温度值来调节大棚内的温度。如果仅靠人工控制既耗人力,又容易发生差错。现在,随着农业产业规模的提高,对于数量较多的大棚,传统的温度控制措施就显现出很大的局性。为此,在现代化的蔬菜大棚管理中通常有温湿度自动控制系统,以控制蔬菜大棚温度,适应生产需要。

1.1系统设计背景
植物的生长都是在一定的环境中进行的,其在生长过程中受到环境中各种因素的影响,其中对植物生长影响最大的是环境中的温度和湿度。环境中昼夜的温度和湿度变化大,其对植物生长极为不利。因此必须对环境的温度和湿度进行监测和控制,使其适合植物的生长,提高其产量和质量。本系统就是利用价格便宜的一般电子器件来设计一个参数精度高,控制操作方便,性价比高的应用于农业种植生产的西红柿大棚温湿度测控系统。
本论文主要阐述了基于AT8Baidu NhomakorabeaC51单片机的西红柿大棚温湿度控制系统设计原理,主要电路设计及软件设计等。该系统采用AT89C51单片机作为控制器,SHT10作为温湿度数据采集系统,可对执行机构发出指令实现大棚温湿度参数调节,具有上下位机直接设置温湿度范围,温湿度实时显示等功能。上位机采用Delphi软件进行编写,用户界面友好,操作简单,可以根据大棚西红柿生长情况绘制成简明直观的作物生长走势图,从而容易得出最适合作物生长的温湿度值。

Abstract
With the popularization of trellis technology, greenhouse trellis an ever-growing number, for vegetable shed speaking, one of the most important management factor is the temperature and humidity control. Temperature is too low, the vegetables will freeze to death or stop growing, so will always control temperature and humidity in a suitable vegetable growth range. Traditional temperature control is in greenhouse trellis internal hanging a thermometer, workers according to regulate the temperature reading the temperature inside the shelter. If only by artificial control both consumption manpower, and easy to place regular orders. Now, with the improvement of agricultural industry scale, for larger quantity of trellis, traditional temperature control measures will show great bureau sex. Therefore, in modern vegetable shed management zhongtong often temperature and humidity automatic control system, in order to control the temperature, adapt to the trellis vegetable production needs.
