Abstract
With the increasing number of Marine accidents, the task of maritime search and rescue is increasingly difficult. This paper studies a fast, accurate and scientifically valid intelligent equipment which breakthrough maritime search and rescue capability and level for maritime search and rescue. Using sonar detection technology combined with GPS navigation systems and Marine battery energy technology, intelligent search and rescue devices which we designed can quickly search for victims of life information. When the sonar equipment is searched for feedback, the GPS provides precise positioning to achieve accurate rescue. The search and rescue device is powered by Marine batteries, which is environmentally friendly and can be supplied for a long period of time. The Marine intelligent search and rescue equipment is equipped with fast speed and strong resistance to wind and waves, which have a long working characteristic and can reach the marine perils area quickly and realize efficient unmanned search and rescue.
