OREANDA-NEWS. NEC Corporation developed a “Failure Sign Monitoring System for Large-scale Plants” that analyzes failure signs from large-scale facilities, such as factories and electric power plants, in order to prevent equipment failures prior to an incident.

NEC’s is driving the adoption of these systems featuring the company’s independently developed big data analysis technologies that automatically detect when sensors, for example, indicate that operations are “different from normal” using internally developed invariant analysis technologies (*), which are used without specialized training or complicated settings.

This new system analyzes information gathered from sensors distributed throughout a facility using invariant analysis technologies. These technologies automatically determine how a facility operates under normal conditions by collecting and analyzing massive amounts of sensor data. This enables the system to compare information under a wide range of conditions, which allows it to quickly detect and understand when abnormal conditions or “failure signs” arise, prior to an actual failure.

As a result, plants can carry out preventative maintenance, thereby improving overall safety and operational effectiveness.
