一、概要本文介绍TDC-3000分散型控制系统采取了一系列强有力的工艺措施来提高硬件的平均无故障工作时间(MTBF),降低硬件的平均修复时间(MTTR)。同时成功地运用了多级递阶分散控制理论,多级操作者接口方法及冗余技术进行系统设计,从而大大提高了TDC-3000的可靠性。工业生产对分散型控制系统可用性的要求至少是99.99％。系统只有大大提高平均无故障工作时间(MTBF)、降低平均修
I. INTRODUCTION This article introduces TDC-3000 distributed control system adopts a series of powerful process measures to improve the hardware mean time between failures (MTBF), reduce the hardware average repair time (MTTR). At the same time, the multi-level hierarchical decentralized control theory, multi-level operator interface method and redundant technology are successfully applied to system design, which greatly improves the reliability of TDC-3000. Industrial production of decentralized control system availability requirements of at least 99.99%. The system only significantly increased mean time between failures (MTBF), reducing the average repair
