1. A people-locating system used in a stationary environment and utilizing UWB technology, comprising:
- at least a UWB emitter having an ID data, said UWB emitter utilizing the UWB technology for wirelessly emitting said ID data;
a system controller used to output a control signal; and
at least a UWB node connected to said system controller and distributed in said stationary environment, said UWB nodes being used to receive said control signal and emit an inquiry signal to said UWB emitter to obtain in turn said ID data emitted by said UWB emitters.

Abstract
A people-locating system and method make use of the UWB wireless data transmission technique in a short distance to build a people-locating system in a stationary environment. The system has at least a UWB emitter, a system controller, and at least a UWB node. Each of the UWB emitters has an ID data. The system controller is used to output a control signal. The UWB nodes are connected to the system controller and distributed in the stationary environment, and are used for receiving the control signal and emitting an inquiry signal to the UWB emitters to obtain in turn the ID data emitted by the UWB emitters.

7. A people-locating method used in a stationary environment utilizing the UWB technology, comprising the steps of:
-
obtaining an ID data of a lost user set on a UWB emitter;
outputting a control signal by a system controller to at least a UWB node distributed in a stationary environment;
searching for said ID data of said lost user by said UWB nodes;
obtaining said ID data of said lost user by one of said UWB nodes;
transmitting a location signal of said UWB node distributed in said stationary environment and said ID data of said lost user to said system controller; and
informing nearby people to go to a location of said UWB node to search for said lost user. - View Dependent Claims (8, 9, 10)
