发明名称 SYSTEM AND METHOD FOR PURSUIT A LOST CHILD
摘要 PURPOSE: A system for tracing a missing child using the size of a location signal transmitted from local distance and a method of the same are provided to sense a missing child occurred within local area, thereby rescuing the missing child in a short time. CONSTITUTION: A missing child occurrence sensor(10) senses occurrence of a missing child by the size of the location signal transmitted from local distance, and generates a missing child occurrence signal. An active location tracer(20) transceives the missing child occurrence sensor and a signal within a broadband area where the missing occurrence signal is occurred, and traces a missing child point into the size and the direction of a received signal. The missing child occurrence sensor includes a location transmitter(11) and a location receiver which generates a location signal periodically(12). If the size of the location signal is less than a critical value, the location receiver generates the missing child occurrence signal.
