Abstract

A data collection device capable of reducing the load of a data collection process and network communication by monitoring trigger at a plurality of cycles is provided. The data collection device includes a control unit, and the control unit includes: an event monitoring unit that acquires first trigger information from the machine tool at a first cycle and monitors whether a starting condition and an ending condition for acquisition of the data have been established on the basis of the first trigger information; a sampling control unit that instructs the machine tool to sample the data at a second cycle shorter than the first cycle when the starting condition is established and instructs the machine tool to end the sampling when the ending condition is established; and a data acquisition unit that acquires the data sampled by the machine tool from the machine tool together with second trigger information.

Claims8

Dependent claims

A data collection device that collects data from a machine tool, the data collection device comprising:

a memory;
and
a processor, wherein
the processor is configured to:
acquire first trigger information from the machine tool at a first cycle and monitor whether a starting condition and an ending condition for acquisition of the data have been established on the basis of the first trigger information;
instruct the machine tool to start sampling the data at a second cycle shorter than the first cycle when the starting condition is established and instruct the machine tool to end the sampling when the ending condition is established;
acquire the data sampled by the machine tool from the machine tool together with second trigger information;
and
monitor whether or not a storage condition for the data has been established on the basis of the second trigger information, store the data in a database when the storage condition has been established, and terminate the storage of the data when the storage condition is no longer established,
a number of the data is set in the storage condition, and
the ending condition is based on the first trigger information or a number of times of data acquisition.
