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。
On the basis of the text (a), it puts forward the technical problems to be solved and the related solutions to solve the problem of “triple play” of telephone, computer and electric power. In other words, it is necessary to expand the communication bandwidth of power lines to increase the communication rate. To improve the anti-interference ability, efficient coupling devices for information and power lines and new modulation and coding technologies must be developed. To form a reliable and efficient information access network, Solve the problem of high-frequency signal crossover transformer and the breaker across the circuit breaker as well as problems with telephone network, computer network interface and networking mode.
