In view of the defects of the existing rescue equipment , such as delayed rescue signals , positioning inability , andlack of energy supplement function , etc. , this paper designs a fast positioning rescue buoy with wave power.Tlhe buoy iscomposed of wave power generation system , positioning and rescue system , and personnel rescue safety system.The deviceintegrates the functions of positioning , rescue,storage and lifesaving , which is a breakthrough from the limitations of the ex-isting lifesaving equipment with a thicket of operation instructions , simple function , and weak marine environment resist-ance.
