Abstract

A log collecting device enabling a grasp of an actuation status based on event logs without a restriction regarding a memory, and an industrial robot and an electric-powered press including the same are provided. A log collecting device 1 is provided on, for example, an industrial robot and an electric-powered press, stores an event log 11 indicating details of an event occurred at an apparatus in a volatile memory 3, creates the collection data 12 that is a collection of the event logs 11, stores this collection data 12 in the volatile memory 3, and deletes the event logs 11 collected as the collection data 12 from the volatile memory 3.

Claims

1. A log collecting device comprising:

a volatile memory storing event logs indicating details of an event occurred at an apparatus;

a collection processing unit creating collection data that is a collection of the event logs; and

a memory controlling unit storing the collection data in the volatile memory, and deleting the event logs collected as the collection data from the volatile memory.

2. The log collecting device according to claim 1, wherein the collection data is a frequency distribution table that counts a number of occurrences of the event log for each time segment.

3. The log collecting device according to claim 2, wherein:

the collection processing unit creates a plurality of the collection data; and

each of the plurality of collection data has a class that contains a current time point, and has a length of the time segment of the class different from the other collection data.

4. The log collecting device according to claim 3, wherein the plurality of collection data are an hourly report that has the time segment of an hour, a daily report that has the time segment of a day, a weekly report that has the time segment of a week, a monthly report that has the time segment of a month, and a yearly report that has the time segment of a year.

5. The log collecting device according to claim 3, wherein each of the plurality of collection data only has the class that contains the current time point, except for the collection data that has the class configured by a longest time segment.

6. The log collecting device according to claim 5, wherein:

the collection processing unit refers to the collection data that has the class with the short time segment, and create the collection data that has the class with the long time segment; and

the memory controlling unit deletes the classes other than the class that contains the current time point from the collection data that has the class with the short time segment after the collection data that has the class with the long time segment is created.

7. The log collecting device according to claim 1, wherein the collection processing unit creates the collection data that have lengths of the time segments of the classes unequal.

8. The log collecting device according to claim 1, further comprising a nonvolatile memory,

wherein the memory controlling unit stores the event logs and the collection data in the volatile memory, and stores the collection data in the nonvolatile memory when a back-up timing comes.

9. The log collecting device according to claim 8, wherein the back-up timing is an occurrence of a specific event.

10. The log collecting device according to claim 1, further comprising an interface capable of reading out and writing in a portable memory medium,

wherein the memory controlling unit stores the event logs and the collection data in the volatile memory, and stores the collection data in the portable memory medium when the portable memory medium is connected to the interface.

11. An industrial robot comprising the log collecting device according to claim 1.

12. An electric-powered press comprising the log collecting device according to claim 1.
