Abstract
A marine emergency position indicating system that can communicate wirelessly between beacon and search engine is provided. When someone carrying the beacon falls into the water, power supply of the beacon opens through drowning automatic switch or manual switch, therefore the beacon can emit wireless SOS signals out. Rescue boat or aircraft installed with search engine can search and receive SOS signals sent from beacons over a 5-kilometer radius along the way to accidental site. The search engine can distinguish the beacons around this area and determine the direction and approximate distance between drowning persons carrying beacons and the search engine through wireless communication technology and wireless positioning technology to help rescuers implement fixed-point rescue. Therefore, the marine emergency position indicating system can overcome the bad weather impact on marine rescue, speed up the rescue process and improve the success possibilities of fixed-point rescue.
