Abstract: A management system for objects under monitoring that is capable of managing the presence of moving objects under monitoring. The management system includes a plurality of beacon terminals, one or more management terminals, and a management server. The beacon terminals are respectively held by the moving objects under monitoring, and each have a unique identifier and broadcast a beacon signal. The one or more management terminals are respectively held by one or more moving bodies moving in one or more areas, receive beacon signals to acquire beacon identifiers and beacon presence information, and acquire location information via a positioning system. The management terminals output beacon information spontaneously or upon request. The management server determines the state of presence of the objects under monitoring in the one or more areas, based on the beacon information acquired from the one or more management terminals.
