基於物聯網技術之訊息佇列遙測傳輸技術於分散式資訊視覺化裝置之開發與實作

快速、有效、便利視覺化資訊顯示一直是資訊系統設計與開發長久以來的重要議題；如何快速、有效的顯示即時資訊從企業資訊化到今日物聯網(Internet of Thing,IoT)，仍是一個刻不容緩的議題，尤其面對今日人們的生活、家庭、工廠及都市等各處角落存在越來越多各式各樣感測器，在日夜不停的蒐集資料，在物聯網的時代，如何將這些資料即時展現給需用者作為各類參考決策用運用成為一個當代的議題。以往傳統的資訊系統開發流程，著重於先前相關需求資訊收集和解析，後續藉由使用者一問一答方式進而進行系統分析與設計，最後進入實作的階段後系統上線給使用者使用，由於物聯網時代感測科技快速變革與需求變更頻繁，感測器型態與數量，甚至感測基地異動更甚於以往，迫使系統升級或變革時，耗時耗力且時間冗長且緩不濟急，雖然感測器的變更或增減隨著感測科技技術進步而變得˙容易且成本不高，但是資訊系統後端系統升級或變革卻無法及時同步，致使資訊獲取與視覺化顯示的時效性產生更大的系統落差。本研究中應用物聯網技術與整合訊息佇列遙測傳輸技術 (message queue te-lemetry transport,MQTT)，透過資訊流(Information Flow)的方式進行開發和實作資訊視覺化裝置，在分散式架構下，開發即時性的分散式資訊視覺化裝置(Distributed Visualized Information Device,DVID)提供使用者進行資訊顯示。研究中將使用ESP32系列的單晶片當為核心處理器，運用點矩陣顯示器(Dot-Matrix Display)設計大型顯示器與薄膜晶體管液晶顯示器(Thin-Film-Transistor Liquid-Crystal Display,TFT LCD) 設計微型顯示器並開發系統雛形進行實證(Proof of Cencept,PoC)，以驗證整個研究的可行性和可用性。宥於研究資源的限制，本研究之感測器收集與雲端平台，直接採用本校曹永忠博士與郭耀文博士開發的『運用物聯網架構之環境監控系統』監控系統並以台中市清水區吳厝國小與新北市新店區新和國小的實際監控站台為實際資料收集對象，本研究不再另行開發系統。關鍵字：物聯網、訊息佇列遙測傳輸技術、資訊流、分散式資訊視覺化裝置、點矩陣顯示器、薄膜晶體管液晶顯示器、環境監控系統。

Rapid, effective and convenient visualized information display has always been an im-portant issue in information system designed and developed for a long time. But how to display fast and efficiency real-time information is still an urgent issue since enter-prise informatization to current Internet of Things (IoT). With sensors collecting data all days, which has been settled in modern lives, families, factories and cities around the world. How to imply those intel in real time for those decision makers has revealed as a modern issue. Traditional information system development process focused on data collection and analysis I previous, followed by the user’s question-and-answer method for the final implementation stage for users. But in the era of the IoT, rapid changed and require-ment of sensing technology, caused the amount and types of sensors increased. And those changes force system to upgrade or get into evolutions. Those improvements caused time, energy, and may not able to fulfill the urgent needs. Though the Im-provements of technologies evolved the sensing-technology and make it cheaper to apply. But those system upgrade and revolutions unable to synchronize in time, which makes great gap between information acquisition and real-time visualized display. In this research, the application of IoT technology integrated with message queue te-lemetry transport technology (MQTT). Through the information flow (Information Flow) method to to develop and implement information visualization devices under the distributed architecture. By which the real-time distributed visualized information device (DVID) could provide users real-time information display. The microprofessor of the ESP32 series is used as the central-processor in this re-search. Meanwhile the Dot-Matrix Display is used to design large-scale displays, and thin-film-transistor liquid-crystal display (TFT LCD) is used to design micro-displays to develop the prototype for proof of concept (PoC) to verify the feasibility and usabil-ity. Due to the limitation of research resources, the sensor collection and cloud platform of this research directly adopts the monitoring system of " The Implementation of an En-vironment Monitor System based on Internet of Thing Architecture " developed by Dr. Yung-Chung Tsao and Dr. Yaw-Wen Kuo. The actual monitoring system of Wu-Tso El-ementary School and Xinhe Elementary School are applied as the actual data collec-tors, thus new system was not developed in this research. Keywords: Internet of Things(IoT), Message Queue Telemetry Transport(MQTT), In-formation Flow, Distributed Visualized Information Device (DVID), Dot-Matrix Dis-play, Thin-Film-Transistor Liquid-Crystal Display(TFT LCD), Environment Monitor System
