〔産業上の利用分野〕
本発明は交換機システムなどにおける軽度障害多発時の
障害装置切り分け方式に関し、特に複数の装置群の中か

に接続されて動作する場合の障害装置切り分け方式に関
する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a system for isolating faulty devices when a number of minor faults occur in a switching system, etc., and particularly relates to a method for isolating faulty devices when a number of minor faults occur in a switching system or the like. This invention relates to a faulty device isolation method when devices are connected in series and operate.

みなす装置群を一意的に決定し、決定された装置群内の
接続装置における一定時間前からその時点までの軽度障
害発生回数を調べ、規定回数以上の軽度障害が発生した
場合その決定された装置が障害であると判定していた。In the conventional failure device isolation method, when a minor failure occurs, a group of devices that are considered to have failed is uniquely determined based on the pattern of the minor failure, and the connected device within the determined device group is identified a certain period of time ago. The number of times minor failures have occurred since then was checked, and if a minor failure occurred more than a specified number of times, it was determined that the device was at fault.

からソウトウエア開発者へ報告されるたびに、ソフトウ
ェア開発者は膨大な後戻りの作業を行う。In the conventional failure device isolation method described above, the relationship between the pattern of frequent minor failures and the group of devices causing the failure is the result of consideration by the hardware designer at the early stage of the design, and it is difficult to make decisions in reality. Whether it is valid or not,
Sometimes we don't know exactly until the product has been tested. On the other hand, the function to actually isolate faulty devices is generally realized in software that is developed in parallel with hardware development, and minor faults discovered before hardware inspection is completed. Every time a hardware developer reports to a software developer a change in a group of devices that is considered to have failed based on the pattern, the software developer must perform a huge amount of backtracking work.

正確に行われないことがある。すなわち、別な装置群で
発生する障害が同一の軽度障害パターンを引き起こすこ
とがある。Furthermore, actual failures tend to be more complex than what designers expected, and it has become impossible to uniquely determine the group of equipment in which a failure has occurred based on a single pattern of minor failures. Therefore, it may not be possible to accurately isolate the group of devices that are causing the failure. That is, failures occurring in different device groups may cause the same minor failure pattern.
さらに、直列に接続された装置群の障害を正確に切り分

ムを大規模化させる。Furthermore, in order to accurately isolate a fault in a group of devices connected in series, it is necessary to insert logic for fault detection between the groups of devices, which increases the overall scale of the system.
本発明は装置ごとの軽度障害発生回数の代わりに、直列
に接続された装置および装置とは独立なことを示す識別
子を配列の要素として軽度障害発生回数を管理すること
により、上述の問題を全て解消することを目的とする。The present invention solves all of the above-mentioned problems by managing the number of times a minor failure occurs by using array elements of serially connected devices and an identifier indicating that the device is independent, instead of the number of times a minor failure occurs for each device. The purpose is to eliminate the problem.

それぞれ１つの装置を選択し選択した装置を直列に接続

装置を配列の要素として障害発生履歴を管理する構成で
ある。The faulty device isolation method of the present invention selects one device from each of a plurality of device groups, connects the selected devices in series and operates them, and when a minor failure occurs, the connected devices are replaced as elements of the array. This configuration manages the history of failure occurrences.

れるため。In this system, a mild fault management method when channels, sub-channels, and input/output devices are each grouped into device groups will be described with reference to FIG. Assume that the route selection of channel 2 - sub channel 3 - input/output device 9 in FIG. 2 has been made. If a minor failure occurs on this route, (1) Number of minor failure occurrences F1 corresponding to channel 2, sub-channel 3, and input/output device 9 (2) Minor failure occurrence corresponding to channel 2, sub-channel 3 Number of times F2 (3) Number of minor failures corresponding to channel 2, input/output device 9 F3 (4) Number of minor failures corresponding to channel 2 4 (5) Minor failures corresponding to sub channel 3, input/output device 9 Number of occurrences F5 (6) Number of minor fault occurrences F corresponding to sub-channel 3
6 (7) Update the number of minor failure occurrences 7 corresponding to the input/output device 9 and refer to it to determine whether a failure has occurred.For example, if sub-channel 3 has caused a failure,
Minor failures should occur on all routes using sub-channel 3, and it is determined that a failure has occurred when the number of minor failure occurrences F6 exceeds the specified number of times, but the number of minor failure occurrences F1 to F5゜F7 is Because each channel is distributed across input and output devices.

In addition, if there is a failure between channel 2 and sub-channel 3, the number of minor failure occurrences Fl and F3 to F7 will not exceed the specified number, but the number of minor failure occurrences F2 will exceed the specified number and it will be possible to isolate the faulty device. Can be done accurately.
