Safe Environment Engineering’s
Life·line® Monitoring System is designed to monitor
the safety of workers in confined spaces such as airplane wings
and fuel tanks. This work environment is subject to statutory laws
and regulations designed to ensure the safety of workers in hazardous
environments.
Regulatory codes require Life·line® to
have 2-way voice communications as well as common alerting capability
for each confined space entrant. Our Personal Safety Monitor (PSM)
is a rugged, specially configured PDA (Personal Digital Assistant).
In addition to flashing lights and vibrations, the PSM communicates
using loud and unambiguous voice commands and alerts. Commands
such as “are you OK, please respond”, or alerts such
as “Warning” and “Evacuate” are difficult
to misinterpret.. The PSM enables wireless voice communications,
responds to periodic “are you OK” queries, and provides
a means to signal for help in case of an emergency.
The Lifeline Monitoring System
with its PSMs and integrated meters and sensors (with their associated
Dongles) works as part of a fail-safe wireless network. This
wireless network is a robust version of those used in homes and
offices. Each PSM and Dongle becomes another component of the
network and communicates through wireless base stations called
Access Points.
Multiple Access Points can be networked
together to provide seamless coverage for cities, buildings or
facilities. All the components of this network can interconnect
so as to ensure no one point of failure causes a disruption in
the connection. The network simply skips over any point not operational.
This type of network architecture is called a MESH network.
If desired, this network can connect
to the Internet providing near unlimited connection options.
