基于Qt的大棚温湿度监控系统设计

The design of the temperature and humidity monitoring system of the greenhouse based on Qt

针对现代化大棚种植技术的需要,设计一种能够实时监控大棚温湿度变化,并将结果实时显示到电脑上,以便用户能够时刻了解大棚内部温湿度变化。系统采用DS18B20采集温度数据;采用HR202L采集湿度数据,以XC7Z020为逻辑控制核心对采集的温湿度数据进行编帧处理,通过串口总线将处理的数据发送到Qt上位机上,Qt将接受到的数据进行可视化处理,以界面的形式实时显示大棚内部温湿度变化,并根据提前设置好的阈值对大棚内温湿度进行相应的调整。实验表明,与传统的人力劳动相比,该系统可以有效的减少成本,提高大棚内农作物的产量,增加人们的经济效益。

In response to the needs of modern greenhouse planting technology,a design that can monitor the temperature and humidity changes in the greenhouse in real time,and display the results on the computer in real time,so that users can always understand the changes in temperature and humidity inside the greenhouse.The system uses DS18 B20 to collect temperature data;uses HR202 L to collect humidity data,uses XC7 Z020 as the logic control core to frame the collected temperature and humidity data,and sends the processed data to the Qt host computer through the serial bus,and Qt processes the received data.Visual processing,real-time display of the temperature and humidity changes in the greenhouse in the form of an interface,and corresponding adjustments to the temperature and humidity in the greenhouse according to the threshold set in advance.Experiments show that compared with traditional human labor,the system can effectively reduce costs,increase the yield of crops in the greenhouse,and increase people′s economic benefits.
