摘要

本研究提出一套環境多感測網路系統，該系統可維持溫室內各區域微環境條件一致，以達到各區域種植標準化的目的。該網路系統主要由多個子感測系統所組成，每個子感測系統裝設於溫室內各區域且皆具有蒐集溫室內各節點之環境訊息(如溫濕度、CO2以及照度等)以及可利用本身內建之知識庫進行環境控制決策，使用者可透過中央主控制系統之人機介面，設定各區域之環境因子參數，經由Zigbee無線發射裝置，傳送資訊給予子系統，子系統則依照所給定參數進行該區域環境調節，達到網路群各區域節點之環境因子條件能夠符合使用者需求。本系統硬體架構包含一主中央控制器、多組次要訊息擷取與控制裝置、多感測模組、多組無線接收與發射裝置。實驗採用一組中央控制器以及4組感測模組(其中1組放置於戶外)，在針對每區域體積60×120×30立方公分的情況下，經由結果可得知，使用本套系統可調控溫室內各區域微環境因子，其系統接收數據資料誤差為0.2%。此套系統的建立已可延伸至雲端控制，可有利於使用者觀察栽培環境內各區域之環境條件，並施予不同的區域環境因子操控，達到雲端環控栽培的目的。

This research establishes a wireless multi-sensors network system to apply to environment sensing and control applications in greenhouse. The use of proposed system can maintain the micro-environmental factor condition consistent for each zone in greenhouse and achieve the purpose of standardized planting. The network system consists of main control, multiple sub-control and sensing system, which collect the environment factor information of each node in greenhouse and perform environment control decision based on expert knowledge database. The user can utilize the graphic user interface (GUI) to setup the desired environment factors (such as temperature, humidity, carbon dioxide, and photo flux) of each zone and then send it to the sub-system via Zigbee module. The environment factor control module of each sub-system will be performed to maintain the desired environment factor setup by the user. The experiment is tested in semi-closed cylindrical chamber which includes four cultivation zones. One sub-system and sensors are installed in each zone (volume: 60x120x30 cm3) and the major system is placed outside the chamber. The experiment result demonstrates that the regulation error of environment factor is totally 12%. The proposed system is helpful for user to observe the variation of environment factor of each cultivation zone remotely through GUI. Meanwhile, the regulation of environment factors is executed automatically. The proposed method can achieve a different manipulation of each cultivation zone for heterogeneous environments.
