基于单片机的温度智能控制系统的软件设计摘要课题是基于单片机的温度智能控制系统的设计，本设计具体到对蔬菜大棚的温度进行控制。蔬菜的生长与温度息息相关，对于蔬菜大棚来说，最重要的一个管理因素是温度控制。温度不合适，蔬菜则停止生长或者生长速度减慢，从而造成不可估量的损失。为此，在现代化的蔬菜大棚管理中通常有温度控制系统，以控制蔬菜大棚温度，适应生产需要。单片机具有体积小、集成度高、性能稳定、控制功能强、易扩展、低功耗、价格便宜等特点，所以单片机市场前景广阔。本设计是通过单片机控制,来实现对蔬菜大棚温度进行控制。系统以AT89C52单片机为基础,通过数字及模拟式对温度进行采集并检测，通过显示屏显示当前温度。当采集到的温度高于系统设定值，马达将带动风扇的转动，从而降低大棚内温度，实现自动控制大棚里的温度。以此为思路设计总体电路原理图，进行软件设计。本设计总体上实现了对大棚温度的控制，有优点但也有不足之处，具有一定的扩展性。【关键词】温度控制 软件设计 温度采集 降温处理AbstractSubject is intelligent temperature control system design based on single chip microcomputer, this design specific to temperature automatic control o-f the vegetable greenhouse.The growth of vegetables and temperature arec-losely related, for vegetable shed, one of the most important managementf-actor is the temperature control. Temperature not appropriate, then stop th-e vegetable growth or growth slowed, causing the immeasurable loss.There -fore, in modern management of vegetable shed, usually with temperature a-utomatic control system, to control the vegetables canopy temperature, to adapt to the requirements of production.Single chip microcomputer with small size, high level of integration, stable performance, easy to control function expansion, low power consum-ption, price cheap and so on, so the single chip microcomputer wide prosp-ect of market.This design is through the single-chip microcomputer control, to realize the canopy temperature vegetables for automatic control. System based on single chip microcomputer AT89C52, through the digital and anal-og temperature in acquisition and detection, through the screen shows the current temperature. When the collected temperature higher than system set-ting, motors will drive the rotation of the fanto reduce the temperature in greenhouses, and realize the automatic control the temperature of the shelte-r. Train of thought to design the overall circuit principle diagram, carries on the software design.This design implements the overall control of the greenhouse temperatu-re, th
