전력선 통신을 이용한 열차내 서비스기기 제어에 관한 연구

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 control 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 control information transmission system using P.L.N. in Train. The proposed system can be applied for automated HVAC system. The system enables HVAC control to be exchanged among couch in train application.
