Description

  The present invention integrates and manages failure information such as abnormalities / failures of a plurality of systems that collect and store information on IP networks and non-IP networks, and extracts maintenance target parts that require inspection or parts replacement. The present invention relates to a system total management system that performs a series of preventive maintenance operations such as replacement parts arrangement, maintenance arrangement, and work instruction to maintenance personnel in the system operation.

  In recent years, in a wide area monitoring and control system for monitoring and controlling rivers, roads, dams, buildings, etc., IP network information is collected and accumulated using, for example, SNMP (Simple Network Management Protocol), PING (Packet Internet Groper), etc. System that collects and stores information on systems managed by, for example, SDH (Synchronous Digital Hierarchy) (non-IP network management device) has been put into practical use. There is a need to construct a system management system that integrates and manages failure information such as abnormalities and failures.

  For example, in the preventive maintenance support system disclosed in Patent Document 1, statistical failure information during operation of the maintenance target system is accumulated by automatic notification, and the accumulated statistical failure information is selected based on a preset monitoring reference value, and the maintenance support center is selected. The system operation is performed without human intervention by determining the consumable parts and the deteriorated parts and arranging a replacement part, a maintenance execution plan, and dispatching maintenance personnel. Thus, a series of preventive maintenance operations are performed quickly, and the purpose is to prevent the system from going down due to a delay in maintenance operations.

In such an example of the management system, the statistical failure information monitoring processing unit reaches a monitoring reference value such that the number of occurrences of correctable errors is 100 times for, for example, a memory, and the number of occurrences of read errors is 80 for a magnetic tape device. Every time, statistical failure information is reported to the maintenance support center as a failure list. Further, in the maintenance support center, the operation state analysis evaluation processing unit has a limit value that is a criterion for determination as a maintenance target part, for example, the cumulative number of occurrences of correctable errors for a memory is 1000 times, and for a magnetic tape device. When the cumulative number of occurrences of reading errors reaches 100 times, it is pointed out as a maintenance target part.

  In the conventional management system as described above, statistical processing is performed on all pieces of failure information, and no consideration has been given to failures that occur secondarily under the influence of certain failures. For this reason, all fault information notified to the maintenance support center is subject to evaluation based on the preset limit values (threshold values) of each device of the system elements, and the maintenance target parts to be inspected or replaced are detected. It was.

  In other words, in the conventional system, not only the failure that is the main cause among the abnormalities and failures that have occurred, but also the failures that occur secondaryly under the influence of this failure are handled in the same way, and the parts subject to maintenance Therefore, there is a problem in that normal parts and devices that do not normally require maintenance work are detected as maintenance target parts. As a result, maintenance work such as inspection and parts replacement is frequently performed, leading to an increase in parts cost and maintenance work cost.

  The present invention has been made to solve the above-described problems, and has an object to improve the accuracy of determining a maintenance target part that needs to be inspected or replaced, and to reduce the part cost and the work cost. To do.

  A system total management system according to the present invention is a system total management system including a maintenance target system and a system total management unit that statistically analyzes and manages failure information for each device constituting the maintenance target system.
