Tricon System Hardware IntroductionTricon 系统硬件基础知识的介绍 ESD Emergency Shutdown System 紧急停车系统 SIS Shutdown Interlock / Instrument System 停车联锁/仪表系统 CCS Compressor Control System 压缩机控制系统 DEH Digital Electro-Hydraulic Control System 汽轮机数字电液控制系统 PDS Product Discharge System 排料系统 ITCC Integrated Turbine Compressor Control 综合透平压缩机控制 Tricon System Major Feature Tricon 系统的主要特点 Tricon System Cofiguration Tricon 系统的构成 Tricon MODULES Tricon 模块 Definition of Tricon – TMR Fault Tolerance Controller: Tricon - TMR 容错控制系统的定义: Identifies and compensates for failed control system elements and allows on-line repair while continuing its assigned task without process interruption. 识别并补偿控制系统的错误 并允许在不影响正常生产的情况下在线维修。 High Safety Integrity - High Safety Availability due to TMR architecture, diagnostics, and on-line repair 高安全性和高可用性 –它是通过三重模件冗余结构（ＴＭＲ）提供容错能力的。此系统由三个完全相同的系统通道组成,自诊断以及在线维修。 High Availability - Eliminates spurious (false) trips 高可用性 - 消除因硬件故障造成的误停车。 Triple Modular Redundancy provides correct control in presence of any Single fault 三重化组件提供正确的控制，即使存在任何单一故障也不影响整体效果。 Ability to operate with 3, 2 or 1 MP(s) before shutdown 停车前的主处理机工作模式为 3-2-1。 On-line repair provides replacement of faulty module without disrupting control 再线维护，提供更换故障组件的能力，且不影响控制（不停车） Number of false shutdowns (trips) reduced 降低因硬件错误而导致停车的次数。 Sequential and regulatory control capability 提供连续控制、顺序控制、逻辑控制的能力。 Comprehensive diagnostics are embedded in the system, independent of user written application programming ! 自诊断内置于Tricon 的硬件内，不需要用户编写应用程序 Tricon TMR TechnologyTricon TMR 技术 Redundancy = No single point of failure 冗余 = 无单点故障 Isolated Architecture 隔离结构 On-line repair possible 再线维护 Triplication - Fully implemented. 三重化 -- 遍布于整个系统 Diagnostics - Embedded in the system 系统诊断-自诊断内置于Tricon 的硬件内 Direct commu
