摘要: 以系统或设备功能框图和信号流程图为基础,构造出故障信息矩阵,通过测试点对故障检测、隔离或定位贡献大小(权数)的分析,用逐步分解矩阵的方法,选出需要的测试点,确定出最佳诊断程序,达到用最少的测试点和最少的时间检测与隔离故障的目的。

Abstract: This paper presents an approach to construct a fault message matrix based on the functional block diagram and signal flow chart of the system or equipment. By analyzing the contribution of the test points to fault detection and fault so lation, the matrix is resolved step by step , the most necessary test points are identified and optimal diagno stic procedure is determined. Thus, the purpose of fault detection and fault iso lation is reached by the use of the fewest test points and a short - time test.

Key words: checkout, malfunction, detection, iso lation
