基于虚拟仪器体温表的设计 摘 要 随着测控技术的研究与发展，测控技术正在向着自动化，智能化，数字化和网络化的方向发展。美国NI公司提出了“软件就是仪器”的概念，所以LabVIEW应运而生。LabVIEW是一种业界标准图形化编程工具，主要用于开发测试，测量和控制系统。由于LabVIEW可以用来创建一个通用的应用程序，它被称为一种通用的编程语言。但是它在测试、测量和自动化等领域有更大的优势，因为LabVIEW提供了大量的工具和功能的数据采集、分析、显示和储存。 检测指标进行实时检测体温在日常生活中常见的温度是必要的，传统的温度计的温度测量和阅读都相对的比较繁琐，传统水银温度计的构造，汞是有毒的，打破后对身体有很大的伤害。与常见的体温表相比，数字体温表更能方便、快捷，并且不会对身体照成危害的测量。所以本文在此基础上介绍了一种既方便测量、读取，又不会对身体造成伤害的基于LabVIEW体温计的设计。本方案采用虚拟仪器的图形编程，数据采集功能，最终实现对体温的精确测量。实验结果表明，此方法对体温的测量简单、易操作和容易读数，有着巨大的应用前景。 关键字：LabVIEW；虚拟仪器；数字体温表 ABSTRACT With the development of measurement and control technology, control technology is toward automation, intelligent, digital and network direction. The United States of America NI company has put forward the concept of software is the instrument emerge as the times require, so LabVIEW. LabVIEW is a leading industry standard graphical programming tools, and is mainly used for system development and testing, measurement and control. Because LabVIEW can be used to create universal applications, therefore is called a general purpose programming language. But it has more advantage in test, measurement and automation fields, because LabVIEW provides a number of tools and functions for data acquisition, analysis, display and storage. Measure temperature in the daily life of the common, is very necessary for real-time monitoring of temperature. The traditional thermometer measurement of body temperature and reading are relatively trouble, and the traditional thermometer is composed by mercury, mercury on the body great harm. Compared with the common thermometer, digital thermometer can be more convenient, fast, and not to the body as a risk measurement. So this paper on the basis of this, presents a convenient measurement, read, and will not cause harm to the design of the thermometer body. The program uses virtual instrument graphical programming, data acquisition function, finally realize the accurate measurement of body temperature, the experimental results show that, t
