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.
Claims9
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 comprising a plurality of frequency distribution tables that counts a number of occurrences of the event log for each time segment;
- and
- a memory controlling unit storing the plurality of frequency distribution tables in the volatile memory, and deleting the event logs collected as the plurality of frequency distribution tables from the volatile memory,
- wherein the collection processing unit creates each of the plurality of frequency distribution tables that has a length of the time segment of a class different from each other and only has the class that contains the current time point, except for the frequency distribution table that has the class configured by a longest time segment.
