Industry 4.0 >> Data acquisition

Data acquisition

Data acquisition is the most advanced function of IMPROVE.

Through it you can achieve the highest level of knowledge useful for improving your productivity. And this is possible thanks to the huge amount of information (data, variables…), acquired directly from the field, which is also useful for training deep learning models.

the most INTELLIGENT way to improve

Configure, acquire, analyze. Decide.

Configuration of Variables

Defining Out of Control

 

In a first step, variables are configured, determining what the acceptable deviation for a given value should be.

Data acquisition

Directly from the field

 

In two ways: automatically from the system (e.g., PLC); manually from the operator.

Data Analysis

Statistical techniques and visual and tabular reports

 

Data analysis makes it possible to simplify information and overcome the “paralysis effect” that can occur at the source of an excessive amount of data.

The Sources

IoT field devices, PLCs, energy meters, various sensors, etc., acquire any kind of data from the field, making it available to be sampled and analyzed by software agents, created ad hoc, for the IMPROVE SystemE.

Another source can be the transformation of other acquired datasets.

IMPROVE

Several types of agents, having different missions, are involved in data acquisition and analysis.

 

  • Agents useful to sample data from the PLC
  • Agents useful to provide the current state of the variables
  • Agents useful to compare this state with previously configured values, thus highlighting outliers and triggering automatic actions of various types

Statistical Process Control

Data analysis techniques

Several tools are used for data analysis, derived from Statistical Process Control:

 

  • variable trending
  • statistical analysis
  • process capability analysis (cp, cpk)
  • histogram (shape of distribution)
  • gaussian analysis

Reports

The results of the analysis phase are embodied in a series of reports: the data are organized both in tabular form and in graphs derived directly from statistical process control.

Visual reports are of various types: frequency histogram, Gaussian analysis, Pareto charts, process capability, up to multivariable analysis, i.e., correlation analysis between variables

"Without statistical control, the process proceeds in an unstable chaos that is bound to mask any improvement attempt."

– William Edward Deming
