摘要

設施栽培需要控制設施環境中的各種環境因子，以適合作物的生長。傳統以電氣控制盤或PLC的方式，去控制驅動相關設備，調節這些環境因子，但總不易達到及時反應、遠端監控及遠端管理等目的。
本研究開發一套設施內環境監控系統，經由OrCAD電路設計分析軟體將電路最佳化設計與分析後，透過控制分析軟體與硬體之結合，使環境監控系統能作環控管理，自動調節設施內部環境，達到最適合植物生長的環境條件，且具有遠端控制及遠端監視、警報之功能。
環控系統由電腦搭配LabVIEW軟體與溫度、濕度、氣體及照度感測器，透過多功能訊號擷取卡PCI DAQ-6014，擷取電壓值數據後，由LabVIEW圖控程式轉換成溫度、濕度、氣體濃度、照度等數值，再整合系統內之LED光源、電路控制元件、加熱冷卻、除溼加濕及加氣排氣等環境控制硬體設備，結合DAQ-6014 DIO輸出點，調控出滿足作物生長的環境，並具有人性化及親合力的近端監控操作界面。再利用DataSocket與WebServer將網路技術導入，整合完成遠端監控系統，使系統達到近端監控操作與遠端監控之目的，完成遠端監控之現場資料收集、遠端控制及遠端監視等功能，使整體系統自動化更趨完善。

Regulating plant growth in a planting facility requires the control of all environmental factors. Traditionally, a control panel or PLC is used to achieve the control and regulation of environmental factors. However, these traditional methods do not easily satisfy demanded functions such as quick response time, remote monitoring, and remote managing.
In order to develop a system to control and monitor internal environment to reach the optimal condition for plant growth, an in-facility environmental control system is developed. Using the OrCAD circuit analysis software for analysis and optimization combined with hardware circuitry, the system is able to perform environmental control and management. The system can also carry out remote monitoring and alarming.
The environmental control system consists of LabVIEW software and sensors that detects temperature, humidity, gas and illumination. The system first uses multifunction data acquisition PCI DAQ-6014 card to read in the environmental data in voltages, then utilizes LabVIEW software to adjust the output control variables in real time. Maintaining optimum environmental conditions is realized by circuitry control elements with the DIO pin of DAQ-6014 as output to manipulate environmental control that humidify or dehumidify heat or cool with LED lighting, and add or remove gas. Moreover, the system has a human-centered interface that supports both on-the-spot and remote administration via the computer’s networking capabilities made possible by Data Socket and Web Server. This functionality enhances the automation of the system.
