中文摘要

随着信息领域各种技术的发展，在数据采集方面的技术也取得了很大的进步，采集数据的信息化是目前社会的主流发展方向。各种领域都用到了数据采集，在石油勘探，地震数据采集领域已经得到应用。随着测控技术的迅猛发展，以虚拟仪器为核心的数据采集系统已经在测控领域中占到了统治地位。

数据采集系统是将现场采集到的数据进行处理、传输显示、储存等操作。数据采集系统主要功能是把模拟信号变成数字信号，并进行分析、处理 、存储和显示。温度数据采集系统广泛的应用于人们的日常生活中。

本文主要介绍了利用labview实现温度采集系统的设计过程，系统结构时利用了labview的虚拟仪器技术，由单片机作为下位机端生成温度信号，通过温度的采集实现对温度数据的采集，预处理，分析，储存和显示。全文的内容主要包括：温度采集系统的制作与调试，自己在本次制作中的不足与展望。

关键词：labview ，温度采集系统

ABSTRACT

With the variety of the field of information technology, in terms of data acquisition technology has made great progress, collect data, information technology is the development direction of the mainstream of society. Various areas of data collection used in oil exploration, seismic data acquisition has been applied field. With the rapid development of measurement and control technology, virtual instrument data acquisition system as the core area have been accounted for in the measurement and control dominance. Data acquisition system is the data collected on-site processing, transmission display, storage and other operations. Data acquisition system main function is the analog signal into digital signal, and for analysis, processing, storage and display. Temperature data acquisition systems are widely used in people's daily life.

This paper describes the use of living to labview temperature acquisition system to achieve the design process, Composed of a single chip microcomputer as the terminal machines generating a temperature signal . Full-text content includes: Temperature acquisition system manufacturing and debugging, in the production of the deficiencies and prospects.

Key words: labview, temperature, collected
