电力线载波程控自动盘

A Power Line Programmed Control Switching Board

针对电力系统载波机自动盘使用的局限性，提出了一种新型程控交换自动盘的实现方案使现有的自动盘用户增加到8门，并能相互接续通话，DTMF小号口和双向4线E／M接口，保证了新型自动盘能与各种程控交换机／电力载波机的配接。论文着重从硬件和软件两方面论述了该装置的实现方案，对改善我国电力载波通信的现状，合理使用载波通道具有较大的实际意义和使用价值。

A new design method for the power line programmed control switching board is presented in this paper to overcome the limitation of the old one.The number of the subscribers is increased to eight. The new board has a lasting and mutual communication function, and provides one bidirectional DTMF and 4-E/M interface. This paper emphasizes on the hardware and software design method of the board in detail. It is of great significance for the inprovement of the power line communication in our country.
