基于单片机stm32f107的多点温度检测系统论文.doc

毕 业 设 计（ 论 文 ）摘? 要随着社会的进步和工业技术的发展，人们越来越重视温度因素，目前许多产品都对温度范围要求严格，但是目前市场上普遍存在的温度检测仪器大都是单点测量，并且有温度信息传递不及时、精度不够的缺点，不利于工业控制者根据温度变化及时做出决定。在这样的形式下，开发设计出一种能够同时测量多点，并且实时性高、精度高，能够综合处理多点温度信息的测量系统就很有必要。本课题以STM32F107单片机系统为核心，并能对多点温度进行实时巡检。DS18B20是一种可组网的高精度数字式温度传感器，由于其具有单总线的独特优点，可以使用户轻松地组建起传感器网络，并可使多点温度测量电路变得简单、可靠。本论文结合实际使用经验，介绍了DS18B20数字温度传感器在单片机下的硬件连接及软件编程，并给出了软件流程图。关键词：温度测量；单总线；数字温度传感器；STM32F107单片机AbstractAlong with the progress of the society and the development of the technology industry, People pay more and more attention to temperature factors, now many pro-ducts strict to temperature range, But on the market at present the prevalence of temperature testing instrument is mostly single-point measurement, And have a temperature information transfer not timely, precision insufficient shortcomings, According to temperature change against industrial controller make timely decision. In this form, development and design a kind of can simultaneously measuring more, and high real-time, high precision, and can handle more comprehensive information system of measurement temperature is very necessary. This topic to STM32F107 single-chip microcomputer system as the core, and able to more real-time temperature inspection. DS18B20 is a network of high precision digital temperature sensor, since it has the unique advantages single bus, users can easily set up sensor network, and can make more temperature measurement circuit become simple and reliable.?In this paper the actual use of experience, this paper introduces digital temperature sensor DS18B20 in under the single chip of the hardware connection and software program- ming, and gives the software flow chart.Key words：temperature measurement；single bus；Digital temperature sensor；STM32F107 single chip；目 录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc200093340 第一章 绪 论 1 HYPERLINK \l _Toc200093341 1.1?课题背景 1 HYPERLINK \l _Toc200093342 1.2 本课题的任务与目标 2 HYPERLINK \l _Toc200093343 1.3 本课题的方案设计 2 HYPERLINK \l
