<P>PROBLEM TO BE SOLVED: To provide a life preserver control system in which a life preserver arrangement state is easily checked. <P>SOLUTION: A QR code 51 in which life preserver information is coded, and an RFID tag 52 in which prescribed information is to be read/written, are attached to each life jacket 50. When the life preserver information of the life jacket 50, and a seat number information of a seat S to which the life jacket 50 is arranged, are obtained for each seat S, the life preserver information of the life jacket 50, and the seat information are related to each other, and written in the RFID tag 52 attached to the life preserver 50 corresponding to the life preserver information, by a mobile terminal 20. Life preserver arrangement information is created by relating each of obtained multiple pieces of life preserver information, to the seat number information, by the mobile terminal 20. On the basis of the multiple seat number information pieces read by the mobile terminal 20, and the life preserver arrangement information, it is determined whether or not, there is a seat S in which the life jacket 50 is not yet arranged, for all RFID tags 52 of the life jackets 50. <P>COPYRIGHT: (C)2012,JPO&INPIT |
