中文摘要 | 本研究目的旨在利用可程式控制器進行精密栽培室環控系統之研製。控制系統以 觸控式人機介面進行環境設定、設備操控及控制結果顯示等。本控制系統之設計以達到精密 控制環境為目的,並可應用於嫁接苗癒合、藥用作物及種子發芽等環控場合。控制方法具有 手動及自動控制等兩種。手動控制可以獨立操作各項設備,包括:冷氣機、加熱器、加濕器 、內循環風扇、植物生長燈、換氣側窗、換氣風扇及室內燈等。自動控制方面,可依據設定 條件來控制室內之溫度、濕度、風速、光照時間和換氣等。 本研究分別以溫度設定17℃∼19℃、25℃∼27℃和30℃∼32℃(代表低、中高溫區),相對 濕度設定80%∼90%為控制目標,進行環控試驗。結果顯示:控制系統在三個溫控區皆可將室 內之溫濕度精準地控制在目標範圍內。 |
英文摘要 | The objective of this study is to develop an environmental control system for a precise culture chamber. For the control system , a programmable logic controller was used to process the logic control and a human-machine interface was used to develop the operator interface. The system could be used in an accurate environmental control situation for plants nursing, such as grafted seedlings, seed germination and herb plants. The control system has both automatic and manual control options. Where system is set at manual control, all of equipment in the chamber, including the air conditioner, humidifier, heater, artificial light, ventilation, and circulating fans can be operated manually. As for the automatic control, temperature, humidity, wind speed, lighting, and ventilation in the chamber can be properly controlled according to the pre-set conditions. In this study, three temperature-control target regions, 17℃~19℃, 25℃~27℃, and 30℃~32℃, respectively for the low, medium and high temperature regions, were chosen to test the performance of the system while the humidity was set at 80%~90%. The results show that the inner environment of the chamber could be precisely controlled for all three cases, and the expected goal could be achieved satisfactorily. |
