To measure finely an underwater state by multiple sensor devices.SOLUTION: An underwater sensor device receives water surface arrangement information including sensor identification information, time information, and positional information transmitted from at least three water surface sensor devices, calculates its own position based on the distance between the water surface sensor device and the underwater sensor device, on the water surface arrangement information, and on its own depth which are derived from the communication delay time between the water surface sensor device and the underwater sensor device, controls the own movement so that the underwater sensor device and the water surface sensor device have a predetermined positional relationship based on the own position and the water surface sensor position, and transmits the sensor measurement data of predetermined measurement items measured at the prescribed measurement timing to the water surface sensor device.SELECTED DRAWING: Figure 1

    【課題】複数のセンサ装置によって水中の状態を精細に計測すること。【解決手段】水中センサ装置は、少なくとも3台の水面センサ装置から送信されたセンサ識別情報、時刻情報及び位置情報を含む水面配置情報を受信し、水面センサ装置との間の通信遅延時間に基づいた水面センサ装置との間の距離と水面配置情報と自己の水深とに基づいて自己の位置を算出し、自己の位置と水面センサ装置の位置とに基づいて自己と水面センサ装置とが所定の位置関係になるように自己の移動を制御し、所定の計測タイミングで計測された所定の計測項目のセンサ計測データを水面センサ装置へ送信する。【選択図】図1
