室內環境的溫溼度是非常基本的環境品質評估項目，尤其在圖書與歷史文物的保存上，常藉由長期持續性的溫溼度監控，以延長文物的保存壽命。本研究提出了分散式儲存的遠距監測架構概念，適合應用於圖書館、博物館、高科技產業等環境，進行長期、持續性與大範圍的環境監測，具有低成本、可攜式、彈性擴充、可靠度高等特點；並針對故宮博物院文物借外展覽時環境監測的需求，設計開發分散式資料伺服器(Distributed Data Server, DDS)，並實際建構「故宮博物院外展環境遠距監測系統」，實際於嘉義縣表演藝術中心「天下第一家：清代帝王文物展」及臺中國立臺灣美術館「女人香：東西女性形象交流展」兩場故宮借外展覽中測試使用，系統能相容於不同展場的網路環境，並且可以視展覽規模彈性擴充、快速設置。藉由本系統，臺北故宮的管理者可以即時掌握臺灣各地，甚至國外各借展點的館藏環境狀況。

Relative humidity and temperature are basic assessments of indoor environmental quality. Both have to be maintained at certain levels to preserve exhibited objects. This paper presents a remote monitoring system based on distributed data storage structure for long term, continuous sensing and recording of relative humidity and temperature. This system was designed for the National Palace Museum for indoor environmental assessment of exhibitions outside the museum. In most environmental monitoring systems, sensing data are sent to a remote centralized database. This system utilizes distributed data server (DDS) as the fundamental unit for sensing, data transmission, storage, and analysis. Sensing data are stored in DDS in different locations, through which users can access real time and historical sensing data via the Internet. This system is low-cost, portable, flexible, and can be easily customized to and installed in various exhibition environments. This system was tested in two exhibitions: “Scent of a Woman: the Collection of Female Subjects in Taiwan”(held at the National Taiwan Museum of Fine Arts, Taichung) and “The First Family under the Heavens: Imperial Art and Artifacts of the Ch'ing Dynasty” (held at the Chiayi County Performing Arts Center). It was found that this system can be easily and quickly adapted to fit different environments. It is valuable for cultural property conservation managers in that they can access DDS in different locations using customized VB program or Internet browser for real time monitoring and analyses of historical sensing data.
