| 摘要: | 有鑒於全球環境的急速惡化，各國政府紛紛開始著手於節能減碳與綠能開
發，並積極推展及運用於公用事業、工商業及居家等領域。以先進讀表基礎建
設(Advanced Metering Infrastructure, AMI)為例，是一套智慧電網(Smart Grid)
系統透過完備的通訊系統及精密系統軟體等開發與建置，首先必須建設基礎設
備智慧型裝置 (Intelligent Device, ID)，包括智慧型表頭(Smart Meter)、監測、
開關、保護設備、控制設備及用戶端管理設備等等。其中，智慧型表頭可透過
有線、無線感知網路與光纖網路等多元技術支援前述應用領域。由應用與技術
發展等不同的面向切入，智慧型表頭的研發強調以人為主要的生活中心，並符
合具有低成本、低耗電、耐用性高及可大量建置等特性。
因此在本論文中我們提出新式讀表技術及架構，使用光學條碼讀取技術於
機械式表頭之應用，設計出機械式滾輪表頭之讀表裝置。在一般機械式滾輪表
頭數字下方標記相對應之條碼，並使用低成本的光學條碼掃描器與機械式數字
滾輪表頭相互整合，以完成表頭數值之讀取功能。如此的設計不僅成本低廉，
並且在斷電時機械式計數器仍可持續運作，同時保留人員檢視數值模式，待復
電後再由光學條碼掃瞄器讀取表頭之最新條碼組合(即最新數值)，再經由網路
回傳最新數值至業者系統端。
本項讀表技術可廣泛地運用於各類機械式表頭，以提供自動擷取數據及即
時遠端監測之數位家庭服務。
In view of the rapid deterioration of the global environment, governments have started to
reduce carbon emissions and green energy development, and actively promote and applied
in public utilities, business and home areas.
Advanced metering infrastructure, for example, is a smart grid system. It was
developed and deployed through completely communication system and sophisticated
system software and others. We must first build intelligent infrastructure devices,
including smart meter, monitoring, switching, protective equipment, control devices and
user management equipment, etc.
Among others, smart meters through cable, wireless sensor network, fiber-optic
network and other techniques can support the aforementioned multiple applications. By
the application and technology development from different sides into, smart meters of R
&D emphasize that people are the main center of life, and meet the features of low cost,
low power consumption, high durability and deployment in large. Therefore, in this thesis,
we propose the new advanced metering technology and architecture, which employs
optical bar-code reading technique to the application in metering devices with mechanical
figure wheel.
In a general mechanical figure wheel, we design a corresponding bar-code to make
the assemblage of a low-cost optical bar-code scanner and a mechanical figure wheel to
complete our proposed metering device. Such a design is not only low-cost and can
continue to operate mechanical counter even in the situation of power off. Meanwhile,
retaining the staff to view numerical figures, after getting power this advanced meter can
read the latest bar-code combination (i.e. the latest value) by a built-in optical bar-code
scanner. Then feedback the latest value to the system of industry client via the Internet.
This meter reading technology can be widely used in various types of mechanical
meters to automatically retrieve data and provide real-time remote monitoring of digital
home services. |
