中文摘要：

温度是影响果蔬干燥过程的重要参数之一。采用探针法设计了一种测试干燥过程果蔬内部温度的系统。该系统以LabVIEW为平台开发虚拟面板,实时显示图形数值温度数据并进行数据保存,有效运用Tab控件实现菜单式友好用户界面;NI9205模块采集信号经过A/D转换,经下位机NI CompactDAQ的USB总线传送至计算机,构建完整的USB数据采集过程。实际应用表明,系统能实时监测干燥过程果蔬内部的温度变化,为干燥过程果蔬内部热传递现象的研究提供有效途径。

英文摘要：

Temperature is one of the important parameters in drying process for fruits and vegetables. A system based on the means of probes to test the internal temperature of fruits and vegetables in drying process is designed. In the system, LabVIEW is used as the platform to develop virtual panel, the temperature data are shown in real-time with graphical figures and stored. Tab control is used effectively to implement the user-friendly interface with menu patterns. Through A/D conversion, the collected signals of NI9205 module are sent to computer via USB of the lower computer NI CompactDAQ, to construct a complete USB data collection process. Practical application shows that the real-time internal temperature variation of fruits and vegetables in drying process can be monitored by the system, thus the basis for researching the phenomenon of heat transfer inside fruits and vegetables in drying process is provided.
