2控制係統之間實現時鐘同步方案
儀表專業技術人員的多次協商,提出的同步方案就是以每套裝置的DCS控制器時間作為時鐘源,每天當DCS控制器時間到達一個固定的時間點時,DCS控制係統發出一個脈衝信號,通過硬接線連接發送給裝置內的其他控制係統,其他控制係統在接收到脈衝信號後,把係統時間修改為該時間點,完成整個裝置時鐘同步。該技術攻關解決了多個控制係統之間綜合故障診斷的瓶頸問題。
3時鐘同步具體實施方案
PX裝置是某化工廠的關鍵生產裝置。它的處理能力是60wt/y。它的主要產品是對二甲苯,副產品包括鄰二甲苯、間二甲苯等化工產品。主體裝置採用的是集散控制係統。緊急停車係統採用的是SIS(safetyinstrumented system)儀表係統。機組控制採用的是獨立的控制係統。
