Abstract

A cell control system capable of estimating a cause of an alarm by estimating an influence of noise in a plurality of machines includes a machine operation instruction unit for transmitting an operation instruction to a managed manufacturing machine, a noise value collection unit for collecting detected noise information, an operation information collection unit for collecting operation information of a manufacturing machine, a learning unit for creating a learning model by performing machine learning using the collected operation information collected as an input signal and the detected noise information as an instruction signal, an estimation unit for analyzing the learning model to estimate operation information corresponding to a noise factor, and an operation instruction change unit for instructing the machine operation instruction unit to change instruction content based on the operation information corresponding to the noise factor.

Claims

1. A cell control system comprising:

at least one manufacturing cell including at least one manufacturing machine; and

a cell controller for transmitting an operation instruction to the manufacturing machine based on a manufacturing plan received from a production planning device,

wherein the cell controller includes

a machine operation instruction unit for transmitting the operation instruction to the manufacturing machine based on the manufacturing plan,

a noise value collection unit for collecting detected noise information,

an operation information collection unit for collecting operation information of the manufacturing machine,

a learning unit for creating a learning model by performing machine learning using the operation information collected by the operation information collection unit as an input signal and the noise information collected by the noise value collection unit as an instruction signal,

an estimation unit for analyzing the learning model created by the learning unit to estimate operation information corresponding to a cause of noise detected by the manufacturing machine, and

an operation instruction change unit for instructing the machine operation instruction unit to change instruction content based on the operation information corresponding to a noise factor estimated by the estimation unit.

2. The cell control system according to claim 1,

wherein the estimation unit performs a prediction using the learning model created by the learning unit to estimate a manufacturing machine having a low noise immunity in the manufacturing machine, and

the operation instruction change unit instructs the machine operation instruction unit to change communication content based on information about a noise immunity estimated by the estimation unit.

3. The cell control system according to claim 2, wherein the operation instruction change unit instructs the machine operation instruction unit to change an operation instruction estimated to affect the manufacturing machine having the low noise immunity estimated by the estimation unit.
