MOBILE-BODY DETECTION SYSTEM, WANDERING DETECTION SYSTEM, AND MOBILE-BODY DETECTION METHOD

摘要

This mobile-body detection system (100) includes the following: a base unit (102); a remote unit (104) that is carried by a mobile body and wirelessly transmits a detection signal; and a plurality of relays (103) that include a mobile relay (105) carried by a movement-capable detection assister. When a relay (103) receives the aforementioned detection signal, said relay (103) sends, to the base unit (102), a notification signal (210) that contains received-radio-strength information (211) indicating the received radio strength of the detection signal. Using received-radio-strength information (211) from a plurality of notification signals (210) sent from a plurality of relays (103) and location information for said plurality of relays (103), the base unit (102) generates information for detecting the location of the abovementioned mobile body.
