摘要 |
A real time location system has a plurality of tag devices. Each tag device has a unique identification code. Each tag device will transmit a location signal when activated. A plurality of location receivers are installed in a fixed location. The location receivers will receive the location signal and calculate a location of the tag device transmitting the location signal. A signal mechanism is coupled to an I/O port of each tag device. The location mechanism provides at least one of an audible signal or visual signal when activated. A location reader is provided. The location reader receives the location data transmitted by the plurality of location receivers to enable a person to locate the tag device transmitting the location signal.
