Data collection and analysis system, data collection and analysis apparatus, machine learning apparatus, and data collection and analysis method

A data collection and analysis apparatus to diagnose an equipment item at a user side for predictive maintenance based on an internal state or operation state of the equipment item, the data collection and analysis apparatus comprising:

• a data acquisition circuitry having a plurality of channels to acquire, from a communicator, data synchronized on a per-group basis for each of a plurality of groups according to setting information, the communicator acquiring the data from the equipment item connected to the data collection and analysis apparatus via wiring and/or a network, the data indicating the internal state or the operation state of the equipment item, the setting information being information in which a channel number, a group, a data acquisition timing, and a storage location of the data, are set for a channel allocated to the data to be acquired from the equipment item, each of the plurality of groups grouping together a plurality of channels having a same data acquisition timing, the data acquisition timing being a timing at which the data are acquired from the communicator;
• and a data analysis circuitry to analyze, for each of the plurality of groups, the data acquired by the data acquisition circuitry, wherein, acquiring the data synchronized for each of the plurality of groups by the data acquisition circuitry is to perform the diagnosis of the equipment item at the user side for the predictive maintenance based on the internal state or the operation state of the equipment item.

A data collection and analysis method to diagnose an equipment item at a user side for predictive maintenance based on an internal state or operation state of the equipment item, the data collection and analysis method comprising:

• causing a programmable logic controller having a plurality of channels to acquire, from a communicator, data synchronized on a per-group basis for each of a plurality of groups according to setting information, the communicator acquiring the data from the equipment item connected to a data collection and analysis system via wiring and/or a network, the data indicating the internal state or the operation state of the equipment item, the setting information being information in which a channel number, a group, a data acquisition timing, and a storage location of the data, are set for a channel allocated to the data to be acquired from the equipment item, each of the plurality of groups grouping together a plurality of channels having a same data acquisition timing, the data acquisition timing being a timing at which the data are acquired from the communicator;
• and causing an arithmetic circuitry to analyze the acquired data for each of the plurality of groups, wherein, acquiring the data synchronized for each of the plurality of groups is to perform the diagnosis of the equipment item at the user side for the predictive maintenance based on the internal state or the operation state of the equipment item.
