摘要
针对传统温湿度监测数据存储、读取不方便且操作复杂等问题,提出了基于LabVIEW的智能温、湿度检测系统.该系统将传感器DHT11所采集到的温度、湿度数据传送至单片机的I/O引脚,再通过虚拟串口将带有时间戳的数据传输至上位机,上位机程序采用LabVIEW实现,可以数字和波形两种方式实时显示温度、湿度,而且可触发温、湿度报警信号,并能以Excel表格存储或者调用历史数据.所设计的系统成本低廉,界面友好,操作方便,功能易于扩展,具有良好的推广应用前景.
In order to solve the problems such as inconvenience of data storage or reading,and complex operation,an intelligent temperature and humidity monitoring system using LabVIEW is designed in the paper.The readings of temperature and humidity gathered by the sensors DHT11 are transmitted to the I/O pins of SCM,and then to the HMI designed by the LabVIEW through the Virtual Serial Port Driver.The temperature and humidity can be shown by waveform or digital in real time.The warning signals can be sent.And finally,the temperature and humidity dates can be stored or read by EXCEL.In short,the designed system has characteristics of low cost,being user-friendly,easy to operate and strong ex-pansibility.So it has a good potential application future.
