전력선 통신을 적용한 열차내 온도제어 시스템 구현 연구

초록

Recently many technology of the P.L.N (Power Line Network) are introduced for an efficient communication. P.L.N transmits information using power line channel. A Heating Ventilation, and Air Conditioning(H.V.A.C) information transmission system is proposed in this paper for the effective transmission. The Power Line Networks have an advantage in low cost because it uses existent power line. It can be easily applied anywhere that a power line socket is available. But the power line channel is very noisy, because many electronic devices in generate electronic noise in modulated signals. This problem should be considered carefully in the design of HVAC information transmission system using P.L.N. The proposed system can be applied for automated Heating Ventilation, and Air Conditioning(H.V.A.C) in train. The system enables HVAC information to be exchanged among cabins or crews or even between a crew and driver in train.
