Along with get into over 21st century, the our country half-hardy industry gets a fast fierce development, regard flower as principle of conduct and actions appreciate with the plant facilities of the gift educate in the big river south north to bloom all over the place, facilities horticulture is seen make is the new industry which has vitality most for 21 centuries.Glasshouse is appreciate a plant cultivation to produce medium essential to have of one of the facilities, different category's appreciating flower's request to temperature also doesn't exert a homology.
Computers have been used to control the environment of the glasshouse with the further development of computer. Control system is made up of central control system, terminal control equipment and sensors. A management program that contains best conditions for each growing stage should be made first. Then it should be stored in the computer memory. Computer affirms and mod the character for each glasshouse according to the management program, and then send orders to the terminal control equipment. The terminal control equipment sends test information to the central control system, and then sends control signals to make electronic mechanical equipment work by orders from central control system. Finally the control of environment is completed. This system automatically can control heating, cooling, increasing humidity, irrigating, and ventilating. Dependent on needs, information is sent to central control part by keyboard so that the environment can be regulated at any time.The use of glasshouse environment automatic control system in the large modern glasshouse is reflection of high technology in growing.
This article will use 8031 monolithic integrated circuits for thetemperature control basic principle example, will design in areal-time control greenhouse the temperature greenhouse temperaturecontrol system. The goal is studies one kind using graduation projectthis period of time to use 8031 monolithic integrated circuits tocarry on the control to the greenhouse temperature the method.

摘 要
进入21世纪以来，我国园艺产业得到迅猛的发展，以花卉为主的作为观赏和礼品的植物设施栽培在大江南北遍地开花，设施园艺被看作是21世纪最具活力的新产业。温室是观赏植物栽培生产中必不可少的设施之一，不同种类观赏花卉对温度的要求也不尽相同。
随着现代科技的发展，电子计算机已用于控制温室环境。控制系统由中央控制装置、终端控制设备、传感器等组成。先编制出温室花卉各生育阶段最适环境条件的管理程序表，存储于电子计算机的记忆装置中，电子计算机根据程序表确认、修正各栋温室内的参数，并给终端控制系统指令。终端控制设备向中央控制装置输送检测信息，根据中央控制装置的指令输出控制信号，使电器机械设备执行动作，实现温室环境调节。该系统可自动控制加热、降温、加湿、灌溉、通风。根据需要，通过键盘将信息输入中央管理室，根据情况可随时调节环境。温室环境自动化控制系统在大型现代化温室的利用，是设施栽培高新技术的体现。
本文将使用8031型单片机对温度控制的基本原理实例化，设计一个实时控制花房内的温度的花房温度控制系统。目的是利用毕业设计的这段时间学习一种利用8031型单片机对花房温度进行控制的方法。
