摘要：邏輯功能測(cè)試屬于核電站DCS系統(tǒng)測(cè)試活動(dòng)的一個(gè)重要環(huán)節(jié)，現(xiàn)有的邏輯功能測(cè)試方法更多地是通過(guò)測(cè)試裝置或信號(hào)發(fā)生器模擬現(xiàn)場(chǎng)傳感器信號(hào)，使用維護(hù)工具人工驗(yàn)證輸出結(jié)果是否符合預(yù)期。現(xiàn)有方法測(cè)試周期長(zhǎng)、自動(dòng)化程度低、測(cè)試效率低、人因失誤率高。本文研究了一種多樣性驅(qū)動(dòng)系統(tǒng)（簡(jiǎn)稱“KDS”）邏輯功能的測(cè)試方法，通過(guò)因果圖法設(shè)計(jì)標(biāo)準(zhǔn)化測(cè)試用例，使用定期試驗(yàn)自動(dòng)測(cè)試工具執(zhí)行邏輯功能測(cè)試用例并已成功應(yīng)用于實(shí)際工程項(xiàng)目。結(jié)合多個(gè)工程項(xiàng)目邏輯功能測(cè)試的實(shí)際應(yīng)用經(jīng)驗(yàn)，證明邏輯功能自動(dòng)化測(cè)試方法不僅提高了測(cè)試效率，同時(shí)降低了人因失誤率，對(duì)后續(xù)核電項(xiàng)目工程測(cè)試應(yīng)用具有較強(qiáng)的參考價(jià)值。

Abstract: Logic function test is an important part of the test activities of DCS system in nuclear power plants. The existing logic function test methods tend to simulate the field sensor signals through test devices or signal generators, where maintenance tools are used to manually verify whether the output results are in line with expectations. Existing methods have the problems of long test cycle, low degree of automation, low test efficiency and high rate of human error.In this paper, a test method of logic function of diverse actuation system (" KDS "for short) is studied. Standardized test cases are designed by means of causal diagram method, and logical functional test cases are executed by means of automatic test tools, which have been successfully applied to practical projects.Combined with the practical application experience of logic function test in several engineering projects, it can be proved that the method of logic function automatic test not only improves the test efficiency, but also reduces the error rate of human factors.

Key words: Diversity actuation system；Digital control system；Logic function；Automated testing
