tion Tag, they can create a virtual fence and apply certain
rules to it. " For instance, if someone is wearing a tag and
they do not have permission to enter a particular zone
within a facility, an alert will be sent to the appropriate personnel
if that person enters that area, " explains Alexander.
" This also works within the efficiency realm regarding
contractors, as it enables facilities to create zones for the
contractors by providing them with tags that allow them
entrance into only the accessible areas of the facility. "
The tag can also be used for safety mustering. " Typically
the muster zone is a designated area and when
there is an emergency or drill, employees report to the
zone, find a supervisor or sign into a sheet that is uploaded
and recorded later to determine how long it took
employees to reach safety. Simplifying the process, Location
Tag creates a muster zone with a virtual fence and
when tagged employees arrive, they are automatically
counted. On the flip side, if someone does not arrive,
an alert is sent and the person can be located by emergency
responders using the sensor on the tag. In addition,
there is a button on each tag that can be pressed
in the event of emergency or injury to send an alert over
the user interface. "
Wearable Technologies, too, is using wearables to
keep industrial workers safer by delivering data-led, actionable
insights in real time to site managers and health
and safety managers. " We are delivering big data relating
to workers, to the data lakes already holding other types
of data such as plant and weather data to facilitate the
application of artificial intelligence across the large enterprise, "
says Bernstein. The company's Eleksen Connected
Worker Solution (Figure 4) provides the ability to
monitor industrial workforces to improve safety and increase
productivity by linking smart garments to a choice
of personal sensor devices, such as for gas, noise and
physiology, to a reporting dashboard that enables managers
to monitor the conditions of their workforce in the
field and onsite in real time, helping mitigate risk, reduce
costs and improve performance.
As wearable technologies continue to improve, they
will become an extension of Industry 4.0, connecting
not just plant data and analytics, but that of worker
productivity and safety, as well. " If you think of sensors
as instrumenting the plant itself, it's not a great leap to
think of them as instrumenting the humans operating
the plant. And, if you can combine IoT from humans
and IoT from the plant, then you will have a complete
picture of your operations, " says RealWear's Jhawar
(Figure 5). " This is important because the maintenance
and reliability performance of the manufacturing operation
depends upon how well the field technicians maintain
the assets, as well as their safety. At the end of the
day, it's all about the effectiveness and efficiency of how
the people in the field interact with the assets that gets
processors to best-in-class operating performance.
Wearables are all about helping individuals be the best
version they can be because they have access to bestin-class
knowledge at all times. "
