摘　　要：在档次低于５８６ 型的微机中都存在千年问题。在２０００ 年到来时，由于日期的错误，将造成数据和报表的混乱。通过对工业控制ＰＣ机中时间系统的基本工作过程的分析，找出千年问题产生的原因。在结合实验进一步掌握千年问题表现方式和规律的基础上，利用中断技术对ＰＣ机的时间系统进行实时监控。所编制的程序已在大庆油田注水站工业现场ＰＣ 机上调试通过，证明是实用可行的。该方法对于２８６ ～４８６There exits the Y2k problem in the PC lower than 586 type.The error of the date will lead to data and report forms in disorder when the year 2000 comes.The cause of the problem has been found by analyzing the basic process of the time system in industrial control PCs. On the basis of further mastering the behavior and the law of the Y2K problem by experiments,the time system is monitored by interrupting technology in real time.The program compiled has been tested at the PC in industrial site of Daqing oilfield injecting water station and proved to be practicable.The methods proposed have both the universality and the applicability to the 286～486 type of the industrial control PCs.
