FIG. 4 is a flowchart showing the processing steps of a method for judging whether the control system shown in FIG. 3 is in an abnormal state based on the equipment information, in a preliminary abnormal state with a sign of abnormality, or in a normal state.

After data collection, in step S11, the stored data is qualitatively determined. Specifically, by performing a differential operation on the data that changes over time, the data is “increased significantly”, “increased”, “no change”, “decreased”, “decreased greatly”. Classify into such states.
In addition, by calculating the standard deviation of the data per unit time, the data is classified into states such as “changed” and “not changed”. Furthermore, the state is qualitatively determined by comparing the maximum value and the minimum value per unit time and monitoring the presence or absence of an extreme value.

Step S12 is a first abnormal pattern inspection step for comparing with an abnormal pattern stored in advance in the abnormal information storage unit 8, and when the result is true.
(Y in step S12), the process proceeds to step S13-1. If false (N in step S12), the process proceeds to step S13-2.

In steps S13-1 and S13-2, the maximum value, the minimum value, the standard deviation, the differential value from the immediately preceding value, the differential value at an arbitrary time, and the This is a calculation step of obtaining an integral value and an integral value within an arbitrary time.

Both steps S14-1 and S14-2 are secondary abnormality inspection steps for inspecting whether or not the results obtained in steps S13-1 and S13-2 match the accumulation pattern.

Step S15-1 is a step of judging that the state is abnormal when it is true in step S12 (Y in step S12) and true in step S14-1 (Y in step S14-1). In step S15-2, when one of the judgments in step S12 and steps S14-1 and S14-2 is false (N in the step) and the other is true (Y in the step), the state is changed. The step of determining that the pattern is a preliminary abnormal pattern that may be abnormal, and the step S15-3 is false in step S12
(N in step S12), and when it is false (N in step S14-2) in step S14-2, the state is determined to be normal.

Through these processes, the data collection interval switching section 5 shortens the data collection interval when the state is abnormal or abnormal. At this time, the data collection interval can be set independently for the abnormal state and the abnormal standby state. Therefore, depending on the state, in the abnormal standby state, the data collection interval can be shortened for more data than in the abnormal state, and the monitoring of the state can be strengthened.

Further, the abnormality information storage unit 8 retains the data by itself when the transition from the abnormal preliminary state to the abnormal state is performed without depending on the instruction from the operator, and converts the abnormal preliminary state pattern into the abnormal state pattern. Can be "upgraded".

[0038]

As described above, according to the present invention, when mounting electronic components, equipment information is not fixedly collected at a constant data collection interval, so that an operator can judge an abnormal state without delay. Information that can be provided.

Further, since unnecessary information is not collected in a steady state, a load is applied to the arithmetic unit, and a high-performance arithmetic unit and a transmission line are always used without affecting other processing time. The need to do so is eliminated.
