Abstract

PURPOSE:To collect a defect data and to analyze a cause centralizing at a center by storing a change in a key input signal of an operation display section in time series in an apparatus control system using a microprocessor. CONSTITUTION:A read/write memory 5 consists of an NXM-bit, where N is the number of input signals and M is the number of stages to be stored. Suppose that a pointer P is in the 2nd column, signals (''1'', ''2'', ''3''-) are in states (phi, 1, phi-), and when the signal ''3'' changes from ''phi'' to ''1'' in this state (phi, 1, 1-), it is stored in the ''2'' column being the present pointer position and the pointer P is advanced in preparation with the next input signal change, and the ''3'' column is pointed out. When the signal ''3'' changes from ''1'' to ''phi'', the state (phi, 1, phi-) is stored in the ''3'' column, and the pointer P is advanced to the ''4'' column. If a defect mode takes place while the pointer 6 is in the ''6'' column, the input signal change is recognized by checking sequentially the stored content from the ''6'' column in reverse order where the pointer P is stopped.

In the past, for failure modes that were thought to be caused by manual keystrokes, a debugging process was performed in which the operator's operating procedures were inferred and repeated reproduction experiments were performed. In addition, for failure modes that are thought to occur with other input signal generation patterns, we have taken steps to infer the generation patterns and repeat similar reproduction experiments. Therefore, in the debugging process and failure analysis in the field, it is not easy to investigate the cause of the failure mode.

Now, as shown in Fig. 4, if a failure mode occurs while the pointer 6 is stopped at the 66th column, then in reverse order from the 6th column where the pointer P is stopped, it is 5°4°3.
.. 2. By sequentially examining the stored contents of 1, M, M-1, . . . , it is possible to know the input signal changes in the input signal change diagram shown in FIG. However, in this figure, the time axis of occurrence has been set appropriately. For example, if each signal corresponds to a key input signal on the operation display section, the operating procedure can be determined by changes in the input signals, and the efficiency of defect analysis or reproduction experiments will be greatly improved.
