摘要

本文之目的主要是研發環境控制技術應用於嫁接苗癒合養生裝置（以下簡稱「裝置」）。該裝置係以條件序控的動作方法作為主要控制架構，並配合溫濕度環境以演譯其控制邏輯。裝置內各控制迴路以低壓工業配線元件為主，使操作及維修上非常簡單及方便，加上省能源的外氣調節設計均解決了目前農家在使用上現實面的難題。本裝置之控制迴路係採用上下限區域及界限啟閉附加延時二種不同條件的邏輯動作方式，在線上運轉結果顯示：該裝置確能依照控制標的適切地調節癒合室內溫濕度環境，並可根據植物生長條件及使用者經驗法則彈性調整出不同的環境管理方式，如光環境與二氧化碳濃度。

The objective of this study was to develop an environmental control technology in acclimatization chamber for grafted seedlings. The nonlinear control methodology with the Condition-Sequence control implementation was adopted as the main control scheme for the system Logic control circuits finished by industrial wiring elements were created to model the tempera, humidity and CO2 control processes. The system was designed for both flexible adjustments to environmental conditions and easy operations for users. Regarding environmental control, if the weather conditions (temperature and relative humidity) are appropriate for grafted seedling curing, the ambient air is directed to regulate the chamber environment in order to save energy. Otherwise, vents in the chamber will be closed to form a close system, and the inner environmental control will be made. Tow control strategies, high-low limit and on-off & time delay control action, were adopted as the main control methodology for the system. Results indicate that the control system can satisfactorily achieve expected goals for providing suitable curing conditions and modulating the environmental factors such as temperature, relative humidity, illuminance and CO2 for grafted seedlings.
