基于LABVIEW的温湿度检测器上位机设计
摘要
随着科学技术的不断发展，测控技术同时也更加的自动化、智能化、数字化和网络化。计算机和生产工具的密切结合是目前科技发展的一个重要的方向。美国NI公司研制并开发的labview虚拟仪器拥有强大的处理数据的能力，拥有良好的人机设计界面，而且能够充分发挥计算机的功能，创造出拥有强大功能的仪器，从而实现普通仪器不能实现的功能。
随着气象事业的不断发展，气象要素的数据测量也进入自动化。因为温度和湿度是两个非常重要环境参数，直接影响到生产生活的正常进行，所以有必要对其进行实时的检测。本设计利用虚拟仪器技术所拥有的易开发、灵活性强和使用方便等一系列的优点，将其和传统测量系统巧妙的结合起来，基于labview 软件可以设计出用来采集多路温度和湿度信号的温湿度检测系统，拥有温湿度数据显示、波形显示、温湿度超限报警等功能，而且操作简单。
本系统运用温湿度传感器，把所采集到的温度和湿度，在计算机软件的运行下，完成自动采集、自动处理、自动保存等功能。

Design of temperature and humidity detector host
computer based on LABVIEW
ABSTRACT
With the continuous progress of science and technology, measurement and control technology to a more automated, intelligent, digital and network. The close combination of the computer and the tools of production is an important direction of the development. American NI company developed developed by LabVIEW virtual instrument has the powerful data processing ability, has the good man-machine interface design, can give full play to the computer function, can create powerful instruments to achieve a common instrument can realize the function.
Advantages, with the gradual development of the meteorological service, meteorological factors measured data also into automation. Temperature and humidity are two important parameters, directly affects the normal production and life for. Therefore, it is necessary to carry the every detection, the design with virtual instrument technology is easy to develop, flexibility and convenient use etc., combined with the traditional measurement system, based on LabVIEW software design a multi-channel temperature acquisition and multiple humidity signal of temperature and humidity detection system, with a temperature and humidity data display, waveform display, temperature and humidity overrun alarm functions and simple operation.
This system uses the temperature and humidity sensors, will be collected by the temperature and humidity, in the support of computer software, automatic acquisition and automatic processing and other functions.
