摘 要 现代农业生产离不开环境控制，随着计算机自动化和单片机技术的不断发展，许多地方都实现了无人值守或智能控制。温度和湿度是日常生产中常见的被控参数，因此对温度和湿度的控制对工农业等日常生产的智能化及自动化相当重要。为此，我们引入了89C51系列单片机。 本次设计的温湿度控制系统可利用单片机对所采集的温湿度数据进行实时检测与分析，并作出及时判断，从而实现温湿度控制的智能化及自动化。其中温度数据的采集是由温度传感器DS18B20将采集的数据转化为数字量，然后被送入单片机中进行处理。湿度数据的采集是由湿度传感器HS1101完成的，然后经A/D转换后，将数字量送入单片机进行数据处理。同时在设备出现故障的时候，语音报警电路和数字显示电路的组合，会更好地是值班人员了解当前的温湿度的具体数值，并提醒维护人员及时采取相应措施。 本文共分为五部分，第一部分是引言，主要对选题背景、意义及国内外发展现状进行简单介绍。第二部分为系统总体方案的设计，主要通过对比集中方案来最终确定本次设计所下用的最佳方案。第三部分为主要单元电路的介绍，有温度测控电路、湿度测控电路、数显电路、报警电路、51单片机的外围电路等。第四部分为主要元器件的介绍，有温度传感器DS18B20、湿度传感器HS1101、51单片机。第五部分为总结，是对本文的高度概括。 关键字: 温度，湿度，智能化 Abstract There is no modern agricultural production without environment control,with the rapid development of computer automation and single chip microcomputer technology,many places have realized unattended or intelligent control.Temperature and humidity are common in daily production was accused of parameters,so to control the temperature and humidity is vital to the automation of industry,agricultural and other daily production.That’s why we introduce the 51 single chip microcomputer. The design of the temperature and humidity control system can use single chip microcomputer to have a real-time detection and analysis on the temperature and humidity data,and then make a in-time judgment ,so as to realize the intelligent and automatic control on the temperature and humidity.Temperature data collected by the temperature sensor DS18B20 transform data into digital quantity,and then be processed into the single chip microcomputer.Humidity data collection was done by HS1101 humidity sensor,then after A/D conversion,the digital quantity into single-chip microcomputer for data processing.At the time of equipment malfunction,the combination of voice alarm circuit and digital display circuit will make it easier for relevant people to check the current temperature and humidity data and remind the maintenance personnel to take corresponding measures in time. The article is divided into five parts,the first
