Application


Anomaly / Abnormal Detection and Predictive Maintenance


Detect the signs and symptom of machine failure before critical damage

Eliminate excessive regular machine maintenance rounds

Minimize maintenance cost

24-hour machine monitoring

Beforehand preparation and smooth spare parts replacement.
Reduce or eliminate machine down time

Remote condition monitoring

Many parameters can be measured and monitored at one place

Product Quality Control


Detect process condition variation from normal operation parameters

Maintain consistent and best quality of final product

Reduce or eliminate NG product

Increase productivity and reduce man hours

Remove man dependent process factors

Visual Inspection


AI to distinguish OK or NG way better than conventional threshold judgement

Decrease miss judgement of OK or NG resulting in higher yield

Reduce workers and cost for inspection

Increase through put

Reduce human dependent error. Eliminate human dependent quality check level

How It Works?

All copyright belongs to NEC Corporation

Extract invariant relationships from time-series data consisting of multiple sensors and create a monitoring model. Invariant analysis technology that detects abnormalities from the current sensor time series using that model.


  • 1. Each relationship captures local characteristics of the target component.
  • 2. By finding a large amount of relationships, the characteristics of the entire system can be found from a different viewpoint than before.
  • 3. It is possible to understand the operation status of the system by monitoring the change of each relationship.

Case Studies

Case 1 – Space Domain Application


Early production testing and operational scenarios studies (before its actual mission in space).

Make it possible to do proactive anomaly detection during design, development, production and test stage. And created system-level Digital Twin.

Built a model of vehicle’s normal operation from about 150,000 sensors to establish over 22 billion logical relationship for analysis.

Case 2 – Automotive Components


Before After
Impossible to monitor Press Components quality in real-time Achieved real-time monitoring.
Excessive redundant machines in case of breakdown. Achieved anomaly detection and reduced number of machines.
Could not find root cause since took time and power only to find out the location where causes defects. Analysis of defective parts by AI using collective data and explored into root cause analysis by operators.

AI solution was deployed to automotive press parts production process. Further to abovementioned improvements,

✓ Customer succeed to launch AI used system within 5 days from its incorporation.
✓ Optimized machine repair and spare parts replacement cycle preventing unscheduled repair work.

Case 3 – Injection Molding Machine


Before After
Defection was found considerably later than when the failure happened. Achieved real time detection
of defection by monitoring unusual
status.
Defective products were disposed though those appearance was good. Realizing early detection before by the defects to happen, considerably decreased defective products.
Noticed machine failure after finding NG product. Able to condition and do maintenance before producing NG product.

This customer used to notice the defective parts after the anomaly of production machine and kept producing defective products though the machine is already unusual. After introducing AI system, customer could find anomaly of injection machine way earlier than before. This resulted in higher productivity and lower disposition of NG products.

Case 4 – Refinery


Before After
To realize early failure detection system to be an advanced technology utilizing refinery. Found important relationship among over 500 sensors (temperature, pressure, flow, valve position and water-level in boilers).
Defective products were disposed though those appearance was good. Spent lots of time and workforce to analyze root cause but couldn’t set up effective system maintenance plan.

This AI solution allows the customer to find failure indication 1 week earlier than previous system based on thresholds and trend analysis and minimize the impact.
