冗余模塊是一種模塊化、可靠性的系統(tǒng)組件，主要用于工業(yè)控制、自動(dòng)化等領(lǐng)域，以確保系統(tǒng)的連續(xù)、可靠運(yùn)行。冗余模塊通常采用雙工或N+1的備份方式，即一個(gè)或多個(gè)備份模塊與主模塊并行運(yùn)行，當(dāng)主模塊出現(xiàn)故障時(shí)，備份模塊可以立即接管，確保系統(tǒng)不受影響。http://www.dtxgl.net/

　　冗余模塊有多種類(lèi)型，包括電源冗余、CPU冗余、I/O冗余等。其中，CPU冗余是指將兩個(gè)或多個(gè)處理器連接到一個(gè)共享存儲(chǔ)器中，它們之間相互監(jiān)測(cè)和協(xié)調(diào)，以確保系統(tǒng)的連續(xù)運(yùn)行。I/O冗余是指對(duì)輸入和輸出信號(hào)進(jìn)行冗余處理，以確保信號(hào)的穩(wěn)定性和可靠性。

冗余模塊的應(yīng)用非常廣泛，例如在電力、交通、石油化工等領(lǐng)域中，對(duì)安全性和可靠性要求較高的場(chǎng)合，都可以采用冗余模塊來(lái)提高系統(tǒng)的可靠性和穩(wěn)定性。

Redundant modules are modular and reliable system components mainly used in industrial control, automation, and other fields to ensure the continuous and reliable operation of the system. Redundant modules usually adopt a duplex or N+1 backup method, where one or more backup modules run in parallel with the main module. When the main module fails, the backup module can immediately take over to ensure that the system is not affected.

　　There are various types of redundant modules, including power redundancy, CPU redundancy, I/O redundancy, etc. Among them, CPU redundancy refers to connecting two or more processors to a shared memory, monitoring and coordinating with each other to ensure the continuous operation of the system. I/O redundancy refers to the redundant processing of input and output signals to ensure signal stability and reliability.

The application of redundant modules is very extensive, such as in the fields of power, transportation, petrochemicals, etc., where high safety and reliability requirements are required, redundant modules can be used to improve the reliability and stability of the system.
