摘　　要：时钟是智能系统的一个基本参数,工业生产过程中各计算机控制系统间的时钟同步对于装置监控操作有着重要意义。一般较大的石化装置内控制系统包括DCS、SIS、ITCC、PLC等,各控制系统之间时钟不同步会给装置安全稳定生产带来很大的隐患。某石化公司芳烃厂各生产装置控制系统间时钟同样存在不同步的问题。该厂相关技术人员通过技术研发解决了这个问题。文章介绍了控制系统时钟出现不同步的原因,进一步阐述了控制系统时钟同步问题的解决方案,最后详细的叙述了装置控制系统时钟同步的具体实施。Clock is a primary parameter for intellgent device, it is significant of clock synchronaziton between computer control systems for process monitoring and controlling in industry manufacture. Control systems, such as DCS, SIS, ITCC, PLC, are used generally in major petrochemical industry unit, and clock imsynchronization will result in a risk of manufacture accident for process. The issue was exist as well in Aromatic Plant of one Petrochemical Company was solved by some relevant technical personnel. It was introduced for the reason of clock imsynchronization, the solution was explained for that further, and the specific implement was described for clock synchronaziton in detail at last in this paper.
