Design and Implementation of the Detecting System for Temperature and Humidity Based on LabVIEW

目前,温湿度监测系统的应用领域越来越广泛,为解决传统温湿度监测系统中存在的问题以及减少系统开发成本,提出了一种基于LabVIEW的温湿度监测系统的设计与实现;系统硬件电路部分由单片机和SHT11组成、应用LabVIEW完成系统数据处理及人机交互软件设计,进而完成温湿度的测量和数据分析;实验结果表明,系统实现了温湿度自动测量、温湿度趋势图绘制、数据显示及存储和超限报警等功能;系统硬件电路简单,人机交互界面友好,设计过程快速、高效,开发成本低。

The application field of detecting system for temperature and humidity becomes wider and wider,in order to reduce the problems in traditional detecting system for temperature and humidity and to decrease the cost in the system development,this paper proposes a kind of design and implementation of detecting system for temperature and humidity based on LabVIEW（ Laboratory Virtual Instrument Engineering Workbench）,applies LabVIEW to completing system data processing and software design for human-machine interaction,whose hardware circuit consists of single chip machine and SHTII,and furthermore implements the detection and data analysis of temperature and humidity. Experiment results show that this system,with simple hardware circuit,friendly humanmachine interaction interface,rapid and high-efficient design process and low development cost,realizes autodetection of temperature and humidity,the drawing of trend diagram of temperature and humidity,data demonstration and storage,and alarm function for the data over the limitation and so on.
