Abstract

To prevent a delay in detection of a fault and the like and to cut down a load on a management side while making transmission of data appropriate in consideration of importance and properties of each type of the data in a case in which a large amount of data is transmitted from management target apparatuses. Items with high priority are processed first, and items with a low priority are allowed to be thinned out in accordance with priority and a weight that a management system 10 defines for each data item, thereby reducing a load. The thinning out is performed by limiting the number of data items to be processed once in accordance with a load level. Data acquisition intervals and priority for each item are dynamically changed by reflecting the importance of the data of each item and a change thereof. Trends of data and the like distributed using telemetry are observed and are fed back to load control through control using an AI or a rule base. In a case in which distribution intervals of each data item are changed, the distribution intervals are changed to a multiple of a basic cycle to curb influences on correlations among the items.

First claim

The invention claimed is:

1. A maintenance management system for managing a plurality of business operation apparatuses, each of which has a function of regularly distributing data using telemetry techniques, the maintenance management system comprising:
a data processing unit, including one or more processors, configured to acquire and process each piece of data that the plurality of business operation apparatuses regularly distribute; and
a load level management unit, including one or more processors, configured to:
cut down the amount of data processing to reduce a load required by the data processing unit to process the data in accordance with a level of the load,
execute, in a case in which a plurality of items are included in the data distributed by each of the plurality of business operation apparatuses, at least one of processing for adjusting the number of data items to be processed by the data processing unit and processing for adjusting time intervals at which each data item is processed,
dynamically adjust, in accordance with a variation in necessity related to each data item, the priority of corresponding data item or time intervals at which each data item is processed, and
raise a priority of a data item in which an abnormal value has occurred or reduce time intervals for processing the data item in which the abnormal value has occurred.

2. The maintenance management system according to claim 1 ,
wherein the load level management unit is configured to define a priority of each data item, and
the data processing unit is configured to process each data item in order from the highest priority and end the processing at a timing at which the number of processed data items reaches an upper limit.

3. The maintenance management system according to claim 1 , wherein the load level management unit is configured to provide feedback to make data items that are processing targets of the data processing unit appropriate, based on a trend of data in each data item.

4. The maintenance management system according to claim 3 , wherein the load level management unit is configured to exclude, from the processing targets, data items with low correlations to a predetermined data item that is highly related to a failure in the business operation apparatus and/or data items that do not change for a specific period.

5. The maintenance management system according to claim 3 , wherein the load level management unit is configured to thin out processing of the data items by doubling time intervals for processing data items with low correlations to a predetermined data item that is highly related to a failure in the business operation apparatus and/or data items that do not change for a specific period.

6. A data processing method for controlling a maintenance management system that manages a plurality of business operation apparatuses, each of which has a function of regularly distributing data using telemetry techniques, the data processing method comprising:
acquiring and processing each piece of data that the plurality of business operation apparatuses regularly distribute;
monitoring a level of a load required by the maintenance management system to process the data;
in a case in which a plurality of items are included in each piece of the data that the plurality of business operation apparatuses distribute, executing at least one of processing for adjusting the number of data items to be processed and processing for adjusting time intervals at which each data item is processed;
cutting down the amount of data processing in accordance with the level of the load;
providing feedback to make data items that are processing targets of the data processing unit appropriate, based on a trend of data in each data item; and
excluding, from the processing targets, data items with low correlations to a predetermined data item that is highly related to a failure in the business operation apparatus and/or data items that do not change for a specific period.

7. The data processing method according to claim 6 , further comprising:
defining a priority of each data item; and
processing each data item in order from the highest priority and ending the processing at a timing at which the number of processed data items reaches an upper limit.

8. The data processing method according to claim 6 , further comprising:
dynamically adjusting, in accordance with a variation in necessity related to each data item, the priority of corresponding data item or time intervals at which each data item is processed.

9. The data processing method according to claim 8 , further comprising:
raising a priority of a data item in which an abnormal value has occurred or reducing time intervals for processing the data item in which the abnormal value has occurred.

10. The data processing method according to claim 6 , further comprising: thinning out processing of the data items by doubling time intervals for processing data items with low correlations to a predetermined data item that is highly related to a failure in the business operation apparatus and/or data items that do not change for a specific period.

11. A maintenance management system for managing a plurality of business operation apparatuses, each of which has a function of regularly distributing data using telemetry techniques, the maintenance management system comprising:
a data processing unit, including one or more processors, configured to acquire and process each piece of data that the plurality of business operation apparatuses regularly distribute; and
a load level management unit, including one or more processors, configured to:
cut down the amount of data processing to reduce a load required by the data processing unit to process the data in accordance with a level of the load,
execute, in a case in which a plurality of items are included in the data distributed by each of the plurality of business operation apparatuses, at least one of processing for adjusting the number of data items to be processed by the data processing unit and processing for adjusting time intervals at which each data item is processed,
provide feedback to make data items that are processing targets of the data processing unit appropriate, based on a trend of data in each data item, and
thin out processing of the data items by doubling time intervals for processing data items with low correlations to a predetermined data item that is highly related to a failure in the business operation apparatus and/or data items that do not change for a specific period.
