摘要： An emergency communication system, while accurately and reliably detecting a location of an object person, receives contact from the object person and grasps a state of the object person when a matter of emergency has occurred. An object person terminal transmits identification information via short-range wireless communication, acquires location information by a GPS function, and transmits the identification information and the location information to a server. A detection terminal transmits the identification information transmitted from the object person terminal. The server specifies the location of the object person terminal on the basis of the information transmitted from the detection terminal or the identification information and the location information transmitted from the object person terminal. The object person terminal, when the occurrence of a matter of emergency is sensed, records ambient sounds as object person sound information, and transmits the recorded object person sound information to the server.

摘要： A position specifying system can accurately detect, while reducing a power consumption amount of a carried terminal, a position within a watching area where the target person acts every day and can efficiently detect the position even in an emergency where the target person moves out of the watching area. The terminal transmits, at a first time interval, identification information via short-range wireless communication; acquires, at a second time interval, position information with a GPS function; and transmits the identification information and the position information to a server via long-range wireless communication. A terminal for detection transmits the identification information transmitted from the communicable target person terminal. The server specifies the position of the target person terminal based on information transmitted from the terminal for detection and specifies the position of the target person terminal based on the identification information and the position information transmitted from the target person terminal.

摘要： A location information sharing control system enables detection of a location of an object person with precision while suppressing power consumption of a terminal carried by the object person, and enables a related person other than a specific manager to grasp the location of an object person. An object person terminal transmits identification information via short-range wireless communication. A detection terminal transmits the identification information transmitted from the object person terminal to the server. The server, on the basis of information transmitted from the detection terminal, specifies the location of the object person terminal, and manages the information on a location information sharing user who shares the information on the location of the object person terminal, and shares the information on the location of the object person terminal with the location information sharing user set to be able to share the information on the location of the object person terminal.
