基于单片机的热敏电阻数字温度计设计摘要此次试验主要是通过研究单片机和转化器工作原理,根据有关的数据处理方式和科学技术的方式,根据单片机的电流表来实时的信息传送。此类机械设备的优势是精确度高、可扩展性强、很强的抗干扰性,与P℃同时还可以开展实时通信。因而我们在本次实验步骤中,针对系统硬件的掌控这方面,使用了单片机为中心的控制板,收集温度元器件大家使用了热敏电阻器。与此同时大家也用了d转换器,将测得的温度和信息进行量化处理后输送到核心业务系统中然后进行转换,所得到的电压值根据外置的数码显示管来显示出最后的温度。这种操作可以使大家更加直观的见到有关温度的表明,与此同时所测得的对应数据信息还可以应用到其他领域中。关键词:数字温度计:温度检测:AT89C51:TLC548ABSTRACTThis experiment is mainly conducted by studying the working principles of thesingle chip microcomputer and the converter,according to relevant data processingmethods and scientific and technological methods,and based on the ammeter of thesingle chip microcomputer to transmit real-time information.The advantages of suchmechanical equipment are high accuracy,strong scalability,strong anti-interference,andreal-time communication with a PC.Therefore,in this experimental step,we used amicrocontroller centered control board to collect temperature components and usethermistors to control the system hardware.At the same time,we also use an ADconverter to quantify the measured temperature and information,and then transmit themto the core business system for conversion.The resulting voltage value displays the finaltemperature based on an external digital display tube.This operation can make everyonemore intuitive to see the indication of temperature,while the corresponding measureddata information can also be applied to other fields.Keywords:Digital thermometer;Temperature detection;AT89C51:TLC548目录摘要.IABSTRACT…第一章绪论】1.1课题的研究背景及意义.…1.2国内外研究现状1.3本设计的主要要求及思路…31.4单片机的发展史3第二章单片机热敏电阻数字温度计的系统设计52.1热敏电阻的概述…2.2系统设计思路5第三章系统硬件设计.83.1单片机AT89C51简介及最小系统设计.83.2显示模块电路设计….103.3AD转换电路与热敏电阻采集电路的设计.123.4无线收发模块电路设计123.5键盘操作模块电路设计13第四章系统的软件设计.144.1主函数模块流程介绍.144.2TLC548转换的子程序.144.3数码管显示子程序.15第五章系统调试…175.1系统测试..17第六章总结….20谢辞.21参考文献.22Ⅲ
