基于LabVIEW和Arduino的茶叶红外杀青机控制系统设计

以Arduino为下位机,LabVIEW为上位机,开发了一套茶叶红外杀青机控制系统。由LabVIEW设计控制系统的前面板,前面板上设计了温度、湿度和滚筒转速等控制按钮,由Arduino采集滚筒内的温度、湿度和滚筒转速等参数,上传至上位机LabVIEW进行分析处理,Arduino根据处理结果控制红外管的开启、风扇电机的正反转和滚筒正反转及转速,从而实现滚筒内温度和湿度的同时控制,使杀青叶不会产生烧焦和闷黄等现象,而滚筒正反转可使鲜茶叶杀青均匀。样机杀青实验验证结果表明,系统运行稳定,杀青均匀,具有良好的杀青效果。

Design of control systemfor cylinder of tea green-removing machine using infrared source based on LabVIEW and Arduino

A control system for t tea green-removing machine using infrared source was developed based on LabVIEW and Arduino, with the And Arduino as the the slave computer and LabVIEW as principal computer. The front panel of the control system was designed using LabVIEW. The control buttons of temperature, humidity and roller speed were designed on the front panel. First, the data of temperature, humidity in the roller and roller speed were collected by Arduino. Then, these data were uploaded to LabVIEW and were analyzed and processed by LabVIEW. According to the processing results, the opening and closing of infrared tube, the positive and negative rotation of fan motor, the positive and negative rotation of the drum and the control of the drum rotation speed were automatically controlled by Arduino. And in this way, the temperature and humidity in the roller could be simultaneously controlled , so that the fresh tea leaves were not burned and heaped for yellowing. And the positive and negative rotation of the drum could ensure that the fresh tea leaves were killed evenly. The control system was used for tea green-removing in prototype. And the prototype test proved that the system was stable, and could achieve uniform and favorable effect of tea green-removing.
