Collection device, collection method, and collection program

Abstract

The present invention provides a collection device, a collection method, and a collection program capable of making detailed data in the past available for viewing according to demand while reducing the volume of communication data in a usual state. The collection device (10) comprises: an acquisition unit (111) that acquires state data about a machine in a predetermined cycle; a first transmission unit (112) that transmits partial data belonging to the state data and matching a first condition set in advance to a management server; a storage unit (12) that stores state data not having been transmitted from the first transmission unit to the management server; and a second transmission unit (113) that, in response to a first command including designation of a time in the past, transmits state data from the designated time onward stored in the storage unit (12) to the management server.

Description

technical field [0001] The present invention relates to a collection device, a collection method, and a collection program for collecting machine state data. Background technique [0002] At present, in the operation management system of industrial machinery including machine tools and industrial robots, in order to manage the operation status of each machine, various status data including various sensor information and command information are collected through the management server. These status data are periodically acquired by the collection device installed on each machine and sent to the management server. [0003] However, as the types and frequency of acquisition of status data increase, or the number of machines to be managed increases, the amount of data transmitted from the collection device to the management server increases, and the communication load and processing load of the management server increase. [0004] Therefore, the amount of data can be reduced by ...

Problems solved by technology

[0005] However, even if an abnormality is detected in the machine and the frequency of sending status data is increased, it is only a detailed collection of information after the abnormality is detected.

Therefore, it is difficult to refer to detailed information of a specific time in the past, including the time when a mechanical abnormality was detected and the time before and after it.
