本文研究自动装置故障诊断问题。具体地说,是以逻辑故障出现的故障诊断。首先回顾一下以前的方法和结果。然后介绍一种叫做“D三次幂算法”的方法。这种方法使人们能从内部和外部描述和计算失效的非循环自动装置的性能状况。接着提出一种叫做“D算法”的算法,此算法利用上述计算法计算检测故障的检查码。先用一个例子介绍一种人工方法。随后借助以Iverson 符号写出的程序精确地阐述D算法。最后表明,在自动装置是由一些AND、NAND、OR和NOR构成的情况下,如果有一检查码存在、D算法就能计算出这样一个检查码。
This paper studies the problem of automatic device fault diagnosis. Specifically, it is a fault diagnosis that appears as a logical fault. First review the previous methods and results. Then introduce a method called “D-th power algorithm.” This method enables one to describe and calculate the performance of a failed acyclic robot from inside and outside. Then put forward a called “D algorithm” algorithm, which uses the above algorithm to calculate the test code to detect the fault. Use an example to introduce a kind of artificial method first. The D algorithm is then elaborated precisely using the program written in Iverson notation. Finally, it is shown that the D algorithm can calculate such a check code if the automatic device consists of ANDs, NANDs, ORs, and NORs if there exists a check code.
