A system comprised of radio frequency transceivers mounted on vehicles and
humans whereby the transceivers detect one another and warn the wearer or
vehicle operator of a possible collision. Fixed hazards such as open holes can
have a portable transceiver setup nearby to warn personnel of the hazard. The
range at which the hazards are detected and warnings issued are programmable.
A
zone in around the operator area of a vehicle can be set up in which the
operator's
tag and the vehicle's tag ignore one another. Special transceivers can be set
up as
'readers' and would collect unit ID's as they passed within the set range and
the
information passed on to a central processor.
