摘要
近年来，IRIG—B码在电力系统时间同步中得到了越来越多的应用。本文介绍一种数字控制的方法，利用CPLD器件，和单片机、GPS卫星接收模块进行配合，用以实现性能良好的IRIG—B码源。该方法中，各个器件之间配合简单，时间精度控制容易，可方便地在电力系统的时间同步工作中实现。
In recent years, IRIG-B code has gained more and more applications for the time synchronization in electrical power system. A digital control method is introduced in this paper, in which a high performance IRIG-B source is achieved by using CPLD to cooperate with SCM and GPS satellite receiver. The method is of simple cooperation for every components and easy control for time precision, it is able to be expediently realized in the ti^e synchronization work of electrical power system.
