内蒙古科技大学本科生毕业设计说明书（毕业论文）题 目：基于 LabVIEW 的热电偶温度记录仪学生姓名：郭晓飞学 号：0605112317专 业：测控技术与仪器班 级：测控 06-3 班指导老师：李文涛教授下载后可任意编辑摘 要温度是表征设备状态的重要物理量，也是传热学中进行分析计算的重要参数，温度测试及记录是工业应用与教学实验中常常遇到的问题。本设计采纳基于LabVIEW的热电偶温度记录仪来实现热电偶温度记录。设计分为硬件设计与软件设计两部分。硬件主要是由热电偶温度传感器、数据采集卡、 PC机组成，主要实现温度信号的采集、转换、处理等功能。采纳LabVIEW8.5进行图形化编程设计了前面板。可以通过用户登录界面进入系统，前面板设计包括温度采集、温度记录、温度查询三部分。在程序框图设计中，编写了用户管理、DAQ采集、通道选择、数据库访问、数据库写入、数据库查询等子VI，实现了对于四个不同通道的数据采集、记录、实时显示、报警及查询等功能。关键词：Lab VIEW；虚拟仪器；温度；采集；记录I下载后可任意编辑AbstractTemperature not only is an important characterization of physical equipment, but also is the heat transfer analysis in an important parameter .The test and record the temperature industrial applications are often experiment with teaching problems. This set of virtual instrument which is based on the thermocouple temperature recorder, is record the temperature of thermocouple. Design is divided into hardware design and software design .Hardware was designed by the thermocouple temperature sensor, data acquisition cards, PC systems, etc. It is mainly temperature signal acquisition, transformation, processing and other functions .Software design used LabVIEW8.5 graphical programming software. The interface can be displayed Temperature acquisition, temperature records and temperature query through user-side. In program design, I prepared a sub-VI (user management, DAQ acquisition, channel selection, database access, database write database query). And they achieved the four differ...
