本篇論文致力研究適用智慧型建築的光網路監控及網際網路接取技術的研究,在智慧型建築標準下,我們在智慧型建築即時監測系統設計,以分波多工式的被動光網路為主要光網路,並使用陣列波導光柵式為被動光網路多工器及解多工器主要元件,中央控制端包含一個獨立的基本監控模組,並且在光網路單元內每個節點,也包含一個獨立的監控波長光纖收發器,利用監控光纖發射器同時到所有建築內節點,並被監控波長光纖接收器接收,所以當任一節點發生問題,系統立即利用光開關切換至監控模組的光時域反射儀,做斷點偵測,在第一架構,監測信號功率消耗 25dB, 下行及上行信號功率消耗,分別為 19dB, 27dB,在此研究首次提出所有節點做高速即時監測並在最快時間做斷點修護,並且可即時當備用系統。
另一提出陣列波導光柵式被動光網路,具備了第一架構上述所有優點,並提出即時監控和斷點偵測可同時運作,具備監測節點功能並不會因其它損害節點的修護而停止,在下行信號和上行信號對稱性設計,光放大器的設計可有效提供功率預算,例如實驗結果:下行信號5dB功率消耗及上行信號12dB功率消耗,使得此架構可適用2.5Gbps及10Gbps高速資料傳輸,而光時域反射儀的偵測路徑設計,巧妙避開上下行放大器,並利用光開關1XN的特性,即使N數目增加,插入損耗仍小於1.5dB,實驗結果在建築節點內,即使距離高達10 km光纖,光時域反射儀仍可有效率正確偵測斷點處。
最後並將智慧型建築標準,系統可架設在一個開放式的系統,達到系統設置成本最低及技術更新快速,本論文提出目前最成熟的技術,網際網路接取,使用微軟公司研發網頁語ASP.net 2.0,做網頁設計,提供系統管理者可管理使用者權限、群組、系統資料即時分析讀取、控制、遠端遙控做系统診斷…等等服務,而網際網路的普遍性使得系统使用者可隨時隨地接取系统資料。
In this thesis, we are concerned with research about WDM-PON monitoring and Internet Access for Intelligent buildings. Following the criteria of Intelligent buildings, we choose the WDM-PON architecture as the optical network and access the center data system through the Internet network. The thesis proposes two architectures of Arrayed-Waveguide Grating (AWG) based WDM network, which mainly cover the functions of traffic and monitor. The monitoring module is located in central office. The monitoring signal can reach each node of an optical network unit, ONU, simultaneously. For the emergency condition, we first use the monitoring module to be a back up solution when the system is shut down.
We propose another interesting monitoring system in chapter four. This system has all advantages of the first structure and provides higher performance for the monitoring function. Monitoring signal and OTDR equipment can be operated together in real time. The system maintains good nodes, whether failed nodes are being fixed or not. Downstream signals and upstream signals can be amplified using EDFAs to efficiently get more power budget. It can be operated from 10Gbps to 2.5Gbps easily. An OTDR test path is designed well to bypass EDFAs and has a good capability for long distances, like 10km, to nodes in an ONU
Finally, we can access the central control system of a building from an open platform, that is, the Internet network. Customers can minimally invest in system installation and get their system upgraded quickly. In a matured network world, anyone can simply access any messages and any system controlled by computers. We use a mature Web Page language, ASP.net 2.0 developed by Microsoft, to develop a web page. System admin can easily manage users and system data by ASP.net 2.0. Any user of a building can access the system from the Internet network anywhere and anytime.
