摘　　要：针对不同解码显示机制的跨整10年过程时间显示异常问题,分析研究了IRIG-B时间码编码规则和时间解析机制。重点通过跨整10年的时间段时间跳变试验对问题剖析,结合不同解码显示机制原理,使用比对方法,得出年信息显示跳变现象,是解码显示机制与现有时间信息编码机制不协调的结论。通过多组时间跳变试验验证了分析的正确性。结果表明,根据不同终端对时间解析显示需求的不同,研究并选择最佳的时间解析显示机制,对判读时间信息显示是否正确具有重要意义。In view of the abnormality of the inter-ten-year process time of different decoding display mechanisms, the paper analyzes and studies the IRIG-B timecode coding rules and time resolution mechanisms. Focusing on the analysis of the problem through the time-hopping test spanned the whole ten years, combined with the principle of different decoding display mechanism, using the matching method, the annual information display jump phenomenon is the conclusion that the decoding display mechanism is not in harmony with the existing time information coding mechanism. The correctness of the analysis was verified by multiple sets of time-hopping tests. The results show that it is of great significance to study and select the best time resolution display mechanism according to the different requirements of different terminals for time resolution display.
