摘　　要：研究了B码校时的原理,设计了B码发生和B码解码功能的时钟同步装置。该系统采用Altera公司的SOPC解决方案,可以准确地同外部输入信号自动保持同步,也可以输出标准的B码和秒脉冲同步信号,向电子式互感器和电子式互感器校验仪提供同步时钟。经过多次现场试验表明,该装置达到了设计要求,取得了较好的应用效果。The principle of IRIG - B code accurate time setting was researched in this paper, the clock synchronization device was designed with the IRIG-B code function and IRIG -B code decode function. The system used in Altera＇s SOPC solution. It can synchronize the external input signal automatically and output the standard IRIG-B code and synchronized signal of second plus. The device provides synchronous clock for the electronic transformer and electronic transformer calibrator. After several field experiments showed that the device meets the design requirements and a-chieves good effect.
