Abstract

PURPOSE:To facilitate the evaluation of the operation stability at the long time operating test and the investigation of a cause to the generation of quasi- normal operation by storing quasi-normal operation information into a peripheral information accumlating section. CONSTITUTION:A peripheral section 1 is provided with a peripheral communication section 1 acting like the communication operation with a main control accumulating section while being controlled by the peripheral control section 2 in a bus 3 of the peripheral control section 2 and a peripheral information accumulating section 5 accumulating the quasi-normal operation information generated during the control operation of the peripheral control section 2. When the peripheral section 1 is started or restarted by the main control section, the peripheral control section 2 starts the peripheral control operation. When the peripheral control section 2 recognizes the quasi-normal operation during the peripheral control operation, the quai-normal operating information (fault content recovered by restart, number of generation of faults and number of times of restart or the like) is stored in the peripheral information accumulating section 5. The accumulating operation is always repeated at the generation of quasi-normal operation.

Description

TECHNICAL FIELD The present invention relates to an information accumulation method, and more particularly to an information accumulation method for accumulating quasi-normal operation information of a peripheral section in a communication system having a main control section and a peripheral section.

Conventionally, in such a communication system, the operation procedure between the main control unit and the peripheral unit is as shown in the block diagram of FIG. When 2 receives a startup or restart signal, the main control unit (
(not shown), and the control operation is normally or abnormally terminated without accumulating failure information or quasi-normal operation information within the peripheral section 1.

Note that 3 indicates a bus.

In the control method for the peripheral part 1 described above, semi-normal operation information in the peripheral part (fault details recovered by restart, number of fault occurrences, number of restarts, etc.) disappears, so stability evaluation during long-term operation tests, semi-normal operation information, etc. It was difficult to investigate the cause of the movement.

Purpose of the Invention An object of the present invention is to cumulatively store quasi-normal operation information in the peripheral area in a storage unit, thereby making it possible to evaluate stability during long-term operation tests and to investigate the cause of quasi-normal behavior. The purpose is to provide an information accumulation method.

According to the present invention, in the peripheral section whose operation is controlled by the main control section, normal operation is indicated as return information in response to a start or restart signal from the main control section. An information accumulation method in a communication control system in which information and failure information indicating the details of the abnormality are sent to the main control section when an abnormality occurs, the information accumulation means being provided in the peripheral section, and the information accumulation method There is obtained an information accumulation method characterized in that the content of the failure recovered by the restart signal, the number of failure occurrences, and the number of restarts are cumulatively stored in the part.

1 亙 3 Hereinafter, the present invention will be explained in detail using the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention, in which a peripheral section 1 is connected to a bus 3 of a peripheral control section 2, and is controlled by the peripheral control section 2.
The configuration includes a peripheral communication section 4 that controls communication operations with a main control accumulation section (not shown), and a peripheral information accumulation section 5 that accumulates quasi-normal operation information generated during control operations of the peripheral control section 2.

When the peripheral section 1 is activated or restarted by the main fli control section, the peripheral control section 2 starts peripheral control operation. During the peripheral control operation, when the peripheral control unit 2 recognizes semi-normal operation, it accumulates semi-normal operation information (details of the fault recovered by restart FJ+, number of fault occurrences, number of restarts, etc.) in the peripheral information accumulation unit 5. The above cumulative operation is always repeated when a quasi-normal operation occurs.

Effects of the Invention As described above, the present invention has the effect of making it easier to evaluate operational stability during long-term operation tests and to investigate the cause of occurrence of semi-normal operation by storing semi-normal operation information in the peripheral information accumulation section. have
