When receiving the transmission request transmitted from the voyage information device 101, the communication unit 20 in the mate information device 121 transmits the latest wreck information held by the detection unit 22 to the voyage information device 101.

Further, the voyage information device 101 may have a configuration in which an AIS (Automatic Identification System) is mounted, and the position information of the consignment ship 152 is acquired regularly or irregularly. In this case, the detecting unit 12 in the voyage information device 101 transmits, for example, a transmission request for the mate ship information to the mate ship information device 121 via the communication unit 10 when determining that the acquired position information of the mate ship 152 satisfies the transmission condition. . The case where the position information of the mate ship 152 satisfies the transmission condition is, for example, a case where the current position of the mate ship 152 is included in a predetermined area, or a case where the wake of the mate ship 152 indicates circulation.

The communication unit 20 in the voyage information device 121 transmits the latest wreck information held by the detection unit 22 to the voyage information device 101 regularly or irregularly, regardless of the reception of the transmission request from the voyage information device 101.
