Abstract

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.
