【Abstract】 One of the crucial points in further application of power line communication (PLC) is the development of its firmware. The firmware is categorized into three parts, the transmission facility, network facility and special facility, by the amalgamation of several networks. The functions of each part are described, and the partition of the function modules of a specific firmware, the hardware design, the interface conditions, and the software module partition are analyzed. The design scheme of the pivotal firmware of PLC is emphasized, such as the transmission equipment, the routers of the access network (AN), the interface unit of information appliance equipment and so on. Finally, this paper summarizes the application of PLC firmware and gives a firmware framework configuration of LAN.更多还原
