PAGE IV PAGE III 基于单片机的温湿度检测系统软件设计 摘 要 随着人们的生活及其生产水平的不断提高，对生活环境和生产环境的要求就显的尤为重要，温湿度的控制就是一个典型的例子，因此温湿度检测系统就是现代生产生活中应运而生的一种智能、快捷、方便可靠的检测系统，特别是在工业生产中如果检测得不准确就会发生许多的生产事故。如化工生产中对温度的检测不当就会导致生产效率的降低和产品质量的下降。而现在所使用的温湿度检测系统通常都是精度为1℃或0.1 要为现代人工作、科研、生活提供更好的更方便的设施就需要从单片机技术入手，一切向着数字化控制，智能化控制方向发展。本设计是以单片机（AT89C52）为核心，配合温度传感器和湿度传感器，以及相关的外围电路组成的检测系统，可以接收所测环境的温度和湿度信号，检测人员可以通过数码管显示的数据，实时监控环境的温度和湿度情况。所有的测量操作都可以通过主机控制软件来实现，温度和湿度传感器得到的测量信号，经电路转换为电信号，然后通过一定的放大经过芯片TLC549A/D转换送到单片机进行数据处理，经软件分析处理后送显示装置。 本系统包括系统硬件和软件设计,可靠性高，结构简单，实现了对温湿度的自动调节。系统还应用RS232与上位机相连接，可以设置自动记录温度、湿度的相关的参数，也可以设置每隔一定的时间自动记录，可用在气象的观察方面。 关键词：温湿度采集，数字采集，AT89C52单片机 Software Design of Temperature and Humidity Measurement System Based on MCU ABSTRACT As the continuous improvement of peoples life and production levels, living environment and production environment for the requirements of most importance to temperature and humidity control is a typical example, the temperature and humidity detection system came into being of modern production and life a smart, fast, convenient and reliable detection systems, particularly in the industrial production will occur if the test was not precise production of many accidents. Such as chemical production in the detection of improper temperature can cause reduced productivity and product quality decline. And now the temperature and humidity detection system used is usually an accuracy of 0.1℃ or 1 ℃ Work for modern, scientific research and to provide better and more convenient facilities need to start from a single chip technology, all toward the digital control, intelligent control direction. The design is based on microcontroller (AT89C52) as the core, with temperature sensors and humidity sensors, and related peripheral circuits of the detection system, can receive the measured signal is temperature and humidity environment, testing officers to the data through the digital display, real-time monitoring the environment temperature and humidity conditions. All of the measurement operat
