| Summary: | 碩士 === 淡江大學 === 電機工程學系碩士在職專班 === 98 === 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.
