摘　　要：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。The traditional control equipment of laboratory temperature and humidity is take the monolithic inte- grated circuits as the core, uses the digital tube to show the humidity value and according to different humidity request to set the different adjustment final state by hardware, thus the humidity of the lab spatial will be con- trolled to the definite value. The virtual instrument technology is used to design a temperature and humidity control system. The LabVIEW and the data acquisition card are used all together to acquire the temperature and humidity signal and output the control signal. The result shows the new system is more vivid and direct-vie- wing, and its operation is more convenient, the function expansion also more easy.
