[Abstract]:The use of the existing distribution line network to achieve data communication between devices can avoid the trouble caused by additional wiring and increase in cost. Distribution line communication is a novel technology with wide application prospect. This paper presents the design of multi-carrier communication system based on DC distribution line. This paper briefly introduces the technologies of multi-carrier communication, carrier coupling and Ethernet communication, and discusses the design principle of distribution line multi-carrier communication system. The hardware circuit of distribution line multi-carrier communication system is designed in detail, including modulation and demodulation module, coupling module, Ethernet interface circuit and power supply module. A multi-carrier communication system with four analog equipment terminals with upper computer as the core is constructed, and the software design of the distribution line multi-carrier communication system is completed. The functions of real-time audio / video transmission, file transmission and text interaction between analog terminals are realized. The test results show that the multi-carrier communication system of distribution line designed in this paper meets the design requirements.
