传统的实验室温湿度控制装置是以Intel 8031单片机为核心,用数码管显示湿度值,根据不同的湿度要求,通过硬件设定不同的调节终态,从而将实验空间的湿度调节到设定值。本系统利用虚拟仪器技术设计制作了一个温湿度测控系统,使用LabVIEW和数据采集卡相互配合采集温湿度信号并输出控制信号。因此,本系统结果显示更形象直观,操作更方便,并且还可以较容易地实现功能扩展。
Traditional laboratory temperature and humidity control device is Intel 8031 microcontroller as the core, with the digital display of humidity, according to different humidity requirements, set the hardware through the different adjustment of the final state, thus the experimental space humidity adjusted to the set value . The system uses virtual instrument technology to design a temperature and humidity measurement and control system that uses LabVIEW and data acquisition card with each other to collect temperature and humidity signals and output control signals. Therefore, the system results show more intuitive and intuitive, easier to operate, and can also be easier to achieve functional expansion.
