Abstract:
A system for locating, positioning and monitoring an object, either inanimate or animate, in a facility, the system comprising:a transmitter member attached to the object, said transmitter member having a power source, a discrete preset encryption code, a radio frequency transmitter circuit for transmitting a preset radio frequency as a transmitter signal for a preset distance, and a process timer for selectively programming a frequency interval for transmitting said transmitter signal; at least one transceiver member positioned within range of said transmitter member, said transceiver member comprising a radio frequency receiver circuit for receipt of said transmitter signal, an interface circuitry in communication with said receiver circuit, and a microprocessor, said interface circuitry and said microprocessor validating said incoming transmitter signal using an embedded algorithm, said transceiver member further including a data storage element for storing incoming data, an input/output circuit for retransmitting said data, and a power supply; a host central processing unit in communication with said transceiver member for receiving said data, said host central processing unit having, a display unit displaying, on a continuous basis, a digital floor plan of the facility, said digital floor plan outlining physical locations of all transceiver members installed in the facility and, for each transceiver, an associated area for receipt of incoming transmitter data; data base software capability for identifying said object; and mapping software capability for monitoring and displaying, on a continuous basis, said digital floor plan of the facility with a location of said object thereon such that, as the object is moved through the facility, its motion is automatically displayed relative to said facility floor plan.
