摘要
为了解决现有红枣干燥机自动化程度低、劳动强度高和不能很好地满足红枣干燥工艺需要的问题,通过对国内外自动化控制系统的研究和借鉴,设计了基于LabVIEW的红枣干燥机的控制系统。同时,设计了LabVIEW控制系统的前面板和程序框图,完成了外部硬件电路的设计。试验表明:该LabVIEW控制系统可以实现鼓风机和物料提升机的启动和停止,3路温度的采集、分析、显示和对加热管的控制,3路湿度的采集、分析、显示和对排湿阀门的控制,2路风速的采集和显示,以及6个进/出风通道按照设定的时间间隔实现5种工作模式的切换。
In order to solve the low automatic degree to existing red jujube dryer, high labor intensity, and not well meet the needs of red jujube drying process, based on the research and reference of the automatic control system at home and abroad, design the red jujube dryer control system based on LabVIEW. Design the front panel and program diagram of the LabVIEW control system, completed the external hardware circuit design. Through the experiments, the LabVIEW control system can realize the blower and material hoist start and stop, three road temperature acquisition, analysis, display and control of the heating tube, three road humidity acquisition, analysis, display and control of the humidity dis charging valve, two road wind speed acquisition and display, six into/out of the wind channel realize five kinds of work-ing mode switching according to the time interval of setting.
