To explain a water flow power generation system and a sailing body that can accurately acquire information based on transmission and reception of sound waves.SOLUTION: A water flow power generation system 1 comprises: a water flow power generation device 2 for floating in water, and generating power by using a water flow; a mooring device 7 for mooring the water flow power generation device 2 in a predetermined water area; an acoustic sensor 30A and an acoustic sensor 30B arranged at positions different from each other, and for transmitting sound waves in the water, and receiving reflected waves of the sound waves; and a control device 40 for detecting the reflected waves received by the acoustic sensor 30A and the acoustic sensor 30B as sound wave signals, and acquiring information based on the sound wave signals. From the detected sound wave signals, the control device 40 identifies first sound wave signals indicating the reflected waves caused by the acoustic sensor 30A, and identifies second sound wave signals indicating the reflected waves caused by the acoustic sensor 30B.SELECTED DRAWING: Figure 3
【課題】本開示は、音波の送受信に基づく情報を正確に取得することができる水流発電システム及び航走体を説明する。【解決手段】水流発電システム1は、水中を浮遊し、水流を利用して発電を行う水流発電装置2と、水流発電装置2を所定の水域に留める係留装置7と、互いに異なる位置に配置され、水中に音波を送信すると共に音波の反射波を受信する音響センサ30A及び音響センサ30Bと、音響センサ30A及び音響センサ30Bが受信した反射波を音波信号として検出し、音波信号に基づく情報を取得する制御装置40と、を備え、制御装置40は、検出した音波信号から、音響センサ30Aに起因する反射波を示す第1音波信号を識別すると共に、音響センサ30Bに起因する反射波を示す第2音波信号を識別する。【選択図】図3
