电力线通信网络 (PLC NET)的推广和应用关键在于其技术体制的建立。文中分析比较了PLC NET的现有标准 ,并指出其不足之处 ,进而结合我国实情提出了PLC NET技术体制的设想 ,其中就PLC NET的网络拓扑结构、网络体系结构、传输频段、调制技术、服务速率、信息跨越技术、家电和网络接口等方面提出了规范要求 ,对数据链路层的帧结构、差错控制和应用语言提出了具体建议 ,对收费制式、安全体系及网络管理也提出了相关措施。
The key to popularizing and applying PLC NET lies in the establishment of its technical system. In this paper, the existing standards of PLC NET are analyzed and compared, and its shortcomings are pointed out. Then the concept of PLC NET technology system is put forward according to the actual situation in our country. The network topology, network architecture, transmission band, modulation technology, Service rate, information spanning technology, home appliances and network interfaces, put forward specific suggestions on the frame structure, error control and application language of the data link layer, and also put forward some suggestions on charging system, security system and network management Measures.
