臺灣博碩士論文加值系統

現今，人們能夠在市面上買到形形色色的電力線網路產品，像是PLC乙太網路轉換器(PLC Ethernet adapter)。不需要鋪設額外的乙太網路線，只需將PLC乙太網路轉換器接上室內電源的插座，電腦就能夠自動地透過電力線連上網際網路。
高速鐵路需要電源供應站提供電力，而overhead supply system則提供了電力纜線這個媒介使電源供應站的電力能夠傳輸到牽引列車的列車頭。如能利用這項系統建立移動式接觸的電力線網路，列車上的乘客即能運用它們的行動裝置透過電力線來瀏覽網際網路。
本論文提出了將電力線網路應於高速電氣鐵路系統的想法。為了實現這個想法，必須要做出一個高速鐵路模擬系統(high-speed railway simulation system, HRSS)。透過這個系統，即能使用室內電力線網路模擬列車上的旅客與網際網路上的伺服器之間的通訊。藉由觀察這個通訊的服務品質，本論文就能分析影響通訊品質的因素以及現實生活中高速電氣鐵路系統應用電力線網路的可行性。

Now days, there are many power-line network products in the market for customers to purchase, such as a PLC Ethernet adapter. No need for extra Ethernet wires, just plug the adapter’s power line into an outlet then the computer could connect to the Internet through the power line. High-speed railway system, which power source is the power substation, the overhead supply system provides power line wires to connect both the power substation and the locomotive. If the power-line communication (PLC) network could be established, the passengers who sit on the train can use their mobile devices to surf the Internet. This paper provides an idea which is using power-line communication network working on the high-speed electrical railway system. In order to implement this idea, a high-speed railway simulation system must be built. With this system, it is possible to simulate the communication between internet servers and passengers’ mobile devices by using indoor power source. By observing the communication`s service quality, this paper could analyze the effects which affect the simulation and consider the possibility of using PLC network working on the high-speed electrical railway system in the real world.
