智能温度控制系统设计 摘要：在日常生活中，温度和温差对我们的生活都有非常大的影响。目前在大城市许多的高档公寓已经实现自动控温，然而在普通公寓并没有实现此类控温系统，因此同高档公寓形成了对比，为实现更多的地方使用自动控温系统，本设计通过单片机实现对温度的恒定控制，更廉价，更方便，适用于普及大多数家庭的使用。对我们的生活会有很大的帮助。智能自动控温全面实现全自动化、无人化，都可减少可控因素带来的损失。设计智能自动控温系统，利用温度感应器、报警器、LED显示器通过对单片机的控制实现智能自动控温，解决由于温度不稳定而带来的一系列问题。 本次设计主要以AT89C51单片机为主控核心，与LED显示器、键盘、报警模块等相关电路结合。利用单片机为设计主核心，外接电路连接LED显示器、键盘、报警模块。预定温室内部温度，当温室内部温度有所升高或降低时，此时通过外接电路连接的报警模块发出警报，通过电加热器来调节温室内部温度从而达到温室内部温度恒定。 关键词：单片机，温度传感器，键盘，LED显示器，电加热器 Design of a Temperature-Control System Abstract In everyday life , the temperature and the temperature difference to our lives have a very big impact. Currently many of the luxury apartments in big cities have automatic temperature control, however, did not materialize in apartments such temperature control system , thus forming a contrast with the high-end apartments , to achieve more places to use automatic temperature control system , the design by MCU constant control of temperature , cheaper , more convenient, suitable for universal use in most families . Our life will be a great help . Intelligent fully automatic temperature control fully automated , unmanned , can reduce the losses caused by uncontrollable factors . Intelligent automatic temperature control system design , the use of temperature sensors, alarm , LED display microcontroller achieved through intelligent automatic temperature control , solve a series of problems due to temperature instability brought about . The design is mainly to AT89C51 master core, combined with the associated circuitry LED monitors, keyboards, alarm module. Use microcontroller as the main core of the design , external circuit connecting the LED display, keyboard, alarm module . The predetermined temperature inside the greenhouse , while the temperature inside the greenhouse be raised or lowered , this time through the external circuit connected to the alarm module alarm , an e
