AVR单片机实现温湿度控制.doc

摘 要 虽然温湿度测量及控制技术的研究已经非常成熟，但却未应用于卫生间中。在本设计卫生间一体化中主要实现卫生间中温湿度的智能化控制，此设计由键盘模块、显示模块、温湿度采集模块和继电器控制模块组成。键盘和显示模块实现了人机互动，通过键盘设计可将卫生间温湿度达到理想状态；继电器控制可将采集到的实际卫生间温湿度与预设值比较并开启相应电器。由于AVR单片机自带模数转换功能，因此在温湿度采集模块设计上与51单片机相比更有优势。整个设计均采用单片机和C语言程序执行，提高了卫生间的可控性和智能性，节省了人力，极大地提高了人们的生活水平。据证实，该设计具有一个广阔的应用前景。 关键词：一体化控制；温湿度采集系统；AVR单片机；键盘；显示 ABSTRACT Athough the measurement and control technology of the temperature and humidity is well established ,but it is not used in the bathroom.In the bathroom integration design mainly realise the intelligent control of temperature and humidity in the toilet, this design is composed of keyboard, display module, temperature and humidity acquisition module and relay control module. Keyboard and display module implements the human-computer interaction, and keyboard design can achieve ideal temperature and humidity state in the toilet; relay control can capture the actual toilet comparative humidity presets to compare with the default and open the corresponding electrical appliances. Due to the AVR Microcontroller have the feature which can achieve analog to digital conversion, so compared with 51 single chip the design of the temperature and humidity acquisition module will have an advantage. The entire design is based on the microcomputer and the c-language program, and it can improve toilet controllability and intelligence while saves manpower and greatly improve peoples living standards. It has been confirmed, the design has a wide range of applications.
