近年來，由於人們對於環境問題的重視，針對環境資訊的技術以及應用有了快速發展。其中對於環境監測的研究主要著重在兩大重點:感測資料的收集機制以及異種觀測系統間整合方法。隨著感測裝置的功能提升 (例如:感測精確度、感測範圍、網路能力與運算能力)，感測裝置本身的運作狀況亦能夠作為環境資訊的參考。本論文提出以簡單網路管理協定為基礎之感測網致能管理架構。為了能夠統一的管理不同功能的土石流感測器，實體土石流感測器管理資料庫被定義在此研究中。管理者能夠描述物件與其屬性進而建立樹狀為基礎之感測網致能管理結構，提供系統與多個感測裝置之間具動態的物件管理以及標準化的管理訊息處理。真對資料存取與收集部分，以感測網致能標準服務格式為基礎能夠提高感測資料的交換性與訊息的相容性。所提出之系統介面則透過Web服務為基礎來整合感測網致能與簡單網路管理協定的服務處理，進而提供及時性與無縫隙的遠端管理服務。

Recently, owing to the attentions of environment issues, the environment monitoring technologies and applications are under rapid development. The research on environment monitoring can be divided into two major aspects: sensing data collection and heterogeneous system integration. With the improvement of sensing devices (e.g., precision, sensing range, Internet connectivity, and computation capability), the operational condition of device is also regarded as the environment information. In this research, an SNMP-based SWE management architecture is proposed. To unite the management of various debris-flow sensors, the entity MIB of debris-flow sensors is defined. Administrator could describe an object and its attributes to construct the tree-based SWE management architecture. This framework provides dynamically managed objects and standardizes the message management between the management system and sensors. Data access and collection are based on SWE standard message format, which is used to enhance exchangeability of sensing data and interoperability of the messages. In the proposed system, the SWE and SNMP services are integrated into Web service based interface, which provides real-time, seamless and remote management services.
