WOODWARD 5466-425 三模块冗余模块 用于提高系统的可靠性和可用性

WOODWARD 5466-425 三模块冗余（TMR）是一种容错技术，其中三个模块同时执行相同的操作，以多数相同的输出作为表决系统的正确输出。TMR是一种常用的容错设计技术，用于提高系统的可靠性和可用性。三个模块同时执行相同的操作，如果其中一个模块出现故障，其他两个模块的正确结果可以掩盖掉故障模块的错误，保证系统正确的输出。由于三个模块是互相独立的，两个模块同时出现错误的概率极小，因此可以大大提高系统的可信性。

WOODWARD 5466-425 Three module redundancy (TMR) is a fault tolerance technology, in which three modules perform the same operation at the same time, and take most of the same outputs as the correct outputs of the voting system. TMR is a commonly used fault-tolerant design technique used to improve system reliability and availability. Three modules perform the same operation simultaneously. If one module fails, the correct results of the other two modules can mask the errors of the faulty module, ensuring the correct output of the system. Due to the fact that the three modules are independent of each other, the probability of errors occurring simultaneously in both modules is extremely low, which can greatly improve the credibility of the system.

TMR is widely used in high reliability fields such as aerospace, power, and transportation. In the aerospace field, due to the extremely high requirements for safety and reliability, TMR is widely used in key systems such as flight control and engine control. In the field of electricity, TMR is used to ensure the stable operation and reliability of the power grid. In the field of transportation, TMR is used in high safety systems such as train control systems and subway signal systems. In a word, WOODWARD 5466-425 three module redundancy is an effective fault tolerance technology, which can improve the reliability and availability of the system. Widely used in fields that require high reliability and security.
