摘要
在文 (一 )的基础上提出了实现电话、电脑和电力“三网合一”所要解决的技术问题和相关的解决思路。即 :要提高通信速率必须拓展电力线的通信带宽 ;要提高抗干扰能力必须研制高效的信息与电力线间的耦合器件及采用新的调制、编码技术 ;要组成可靠、高效的信息接入网 ,必须解决高频信号翻越变压器和跨越断路器断口的问题以及与电话网、计算机网络接口与组网方式问题。
This paper presents the technological problem of the convergence of three networks: telephone, computer and electric power and its solution idea is given, that is, high data rates can only be achieved using higher frequencies; high anti-jamming performance needs to research and develop the high efficiently coupling unit between the cable and power line and the latest technology of modulation and coding; composing a reliable and high-effective access networks must solve the problem of high frequency signal bypassing the transformer and passing the outlet of the broken broker and the interface between the PSTN, Internet and power line grid.
