Abstract
An information collection device comprising circuitry configured to: accumulate, in a database, a control signal of a local device having a motor, the local device being a part of a production system of one or more workpieces, the control signal including internal information of the local device generated during operation of a plurality of processes; extract a signal set accumulated during one process of the plurality of processes from the control signal accumulated in the database based on a predetermined extraction condition; and generate an evaluation result of the one process based on the signal set.
Claims20
An information collection device comprising circuitry configured to:
- accumulate, in a database, a control signal of a local device having a motor, the local device being a part of a production system of one or more workpieces, the control signal including internal information of the local device generated during operation of a plurality of processes;
- accumulate, in the database, program information on a program for operating the local device to execute the plurality of processes;
- identify a part of the program corresponding to one process of the plurality of processes based on a predetermined extraction condition and the program information;
- extract from the control signal accumulated in the database, a signal set that is accumulated during the one process of the plurality of processes and that is associated with the part of the program in the database;
- and
- generate an evaluation result of the one process based on the signal set.
An information collection method comprising:
- accumulating, in a database, a control signal of a local device having a motor, the local device being a part of a production system of one or more workpieces, the control signal including internal information of the local device generated during operation of a plurality of processes;
- accumulating, in the database, program information on a program for operating the local device to execute the plurality of processes;
- identifying a part of the program corresponding to one process of the plurality of processes based on a predetermined extraction condition and the program information;
- extracting, from the control signal accumulated in the database, a signal set that is accumulated during the one process of the plurality of processes and associated with the part of the program in the database;
- and
- generating an evaluation result of the one process based on the signal set.
A non-transitory memory device having instructions stored thereon that, in response to execution by a processing device, cause the processing device to perform operations comprising:
- accumulating, in a database, a control signal of a local device having a motor, the local device being a part of a production system of one or more workpieces, the control signal including internal information of the local device generated during operation of a plurality of processes;
- accumulating, in the database, program information on a program for operating the local device to execute the plurality of processes;
- identifying a part of the program corresponding to one process of the plurality of processes based on a predetermined extraction condition and the program information;
- extracting, from the control signal accumulated in the database, a signal set that is accumulated during the one process of the plurality of processes and associated with the part of the program in the database;
- and
- generating an evaluation result of the one process based on the signal set.
