摘要：核電廠數(shù)字化儀控系統(tǒng)根據(jù)標(biāo)準(zhǔn)要求需要對(duì)內(nèi)存進(jìn)行診斷。為了 解決物理內(nèi)存地址操作問(wèn)題，提高內(nèi)存診斷覆蓋率，并提升診斷效率， 設(shè)計(jì)了一種基于實(shí)時(shí)操作系統(tǒng)的內(nèi)存診斷方法。采用March C-算法，診 斷范圍可覆蓋全部?jī)?nèi)存，在不影響操作系統(tǒng)中其他進(jìn)程執(zhí)行的情況下， 能夠快速、安全地檢測(cè)內(nèi)存。該方法已經(jīng)應(yīng)用在防城港核電廠3# 、4#機(jī) 組的事故后監(jiān)視系統(tǒng)中，對(duì)我國(guó)后續(xù)核電廠數(shù)字化儀控系統(tǒng)的開發(fā)具有 借鑒和指導(dǎo)意義。

Abstract: The digital I&C system of nuclear power plant needs to  diagnose the memory according to the requirements of the standard.  In order to solve the problem of physical memory address operation,  improve the memory diagnosis coverage, and improve the diagnosis  efficiency, a memory diagnosis method based on real-time operating  system is designed. Using the March C- algorithm，the diagnosis range  can cover all the memory, and the memory can be tested quickly and  safely without affecting the operation of other application software  in the operating system. This method has been applied to the postaccident monitoring system of Fangchenggang nuclear power plant  No.3 and No.4 units, and has reference and guiding significance for  the development of my country's subsequent nuclear power plant I&C  system.

Key words: Nuclear power plant; Digitization; Instrumentation and  control; RAM diagnosis; March C; Stack check
