So in view of increasing the successful rate for communication effectively, this paper brings forward some ideas such as communication during voltage across zero point, static software relay and communication during suitable time log,and provides the designing scheme of a three-class syste.
本文从有效提高通信成功率出发,提出了过零点通信、静态软件中继技术、通信时段选择等概念,并给出了三级系统的设计方案,可较大幅度地提高系统的性价比。
