基于USB接口的智能温湿度检测仪

Research on the Intelligent Measure Instrument of Temperature and Humidity Based on USB Interface

基于USB接口的智能温湿度检测仪可实时检测、记录和显示温湿度及露点值,并滚动显示日期和时间,且掉电后数据不会丢失。与上位机(PC机)相连,既能实时绘制温湿度变化曲线,又可将记录的数据进行统计分析处理,生成Excel报表,计算任意测试时段的温湿度最大值、最小值、平均值和方差。该仪器与上位机的通讯采用USB接口,即插即用,增强了检测仪的通用性,使用方便。

The intelligent measure instrument of temperature and humidity based on USB interface has the following functions： real-time examining,saving and showing the temperature,humidity,and the dew point of an environment;rolling demonstration of date and time,and saving all data records when the power is off.It can not only dynamically draw the temperature-time and humidity-time curve,but also perform the statistical analysis on the data saved by the instrument and produce a report in the Excel format.The system can calculate the maximum,the minimum,the average and the variance of the data records.The instrument communicates with on a personal computer via a USB interface.In this way,the instrument can be conveniently used to measure temperature and humidity in a variety of environments.
