8120E 冗余控制系统框架

8120E是Triconex公司的产品，它是一种主机箱，产品类型为冗余控制系统框架。
Triconex公司的8120E是基于三重模件冗余（TMR）结构的最先进的容错控制器，它将三路隔离、并行的控制系统和独立的诊断电路集成在一个系统中，三取二表决方式提供高度完善，无差错，不间断的过程控制，不会因单点故障而导致系统实效。此外，该设备还获得TUV AK6级、NFPA72、 FM、CSA等认证，适用于各种规模的关键控制及安全保护系统。它的典型应用行业有石油化工、煤化工、地方化工、铁路交通等，典型应用系统包括安全仪表系统（SIS） 、灾及气体检测保护系统（FGS） 、大型透平压缩机智能及优化控制系统（CCS/iMEC） 、发电机组综合控制系统（DEH） 锅炉燃烧管理系统（BMS）等。

冗余控制系统框架是一种在系统中增加备份系统或组件来提高系统可靠性和稳定性的架构。
冗余控制系统框架在计算机领域中，被广泛用于提高数据传输的可靠性、稳定性以及保障数据的安全。在控制系统中，冗余架构通常是主动式冗余架构，它要求冗余节点能够自动检查主备节点的运行状态，并且在主节点失败时自动切换到备节点。

The 8120E is a Triconex main box for redundant control system frames.
The Triconex 8120E is the most advanced fault-tolerant controller based on triple module redundancy (TMR) architecture, which integrates three isolated, parallel control systems and independent diagnostic circuits in a single system, providing highly complete, error-free, uninterrupted process control with no single point of failure to compromise system performance. In addition, the equipment is also TUV AK6, NFPA72, FM, CSA certification, suitable for all sizes of critical control and safety protection systems. Its typical application industries are petrochemical, coal chemical, local chemical, railway transportation, etc. Typical application systems include safety instrumentation systems (SIS), disaster and gas detection and protection systems (FGS), intelligent and optimized control systems for large turbine compressors (CCS/iMEC), integrated generator set control systems (DEH) and boiler combustion management systems (BMS).

A redundant control system framework is an architecture that adds backup systems or components to a system to improve system reliability and stability.
Redundancy control system framework is widely used in computer field to improve the reliability and stability of data transmission and to ensure the security of data. In the control system, the redundant architecture is usually an active redundant architecture, which requires the redundant nodes to automatically check the running status of the active and standby nodes, and automatically switch to the standby node when the primary node fails.
