DESIGN COMPUTER NETWORK BY USING POWERLINE

In this paper, a powerline medium computer network system is introduce d. By using the AC power supply line which already exist and a special physical interface communication networking among many computer stati ons can by done conveniently. Based on the analysis of powerline chara cteristics, the paper discusses the physical interface that is the key technologies connected with computer network. It includes coupled cir cuit and filter circuit which are the key link of isolating alternatin g current power and filtering the interfered noise. This system is des igned according to CSMA network communication protocol and the high-la yer protocol software is discussed in detail. Many experiments as scre en conversations, disk files transmission and shared print have proved that the performance of the system is good, the data transmission is correct, (C) 1998 Elsevier Science Ltd.
