Research and Demonstration Application of Intelligent Alarm Lifejacket based on BeiDou Communication
In response to the problem of traditional life jackets lacking positioning alarm function in the event of a"separation of people and ships"drowning accident,which leads to difficulties in search and rescue,low efficiency of carpet style search and rescue methods,and easy missed golden rescue time,this paper develops a small low-power intelligent alarm terminal based on BeiDou communication,which can achieve communication blind spot alarm function throughout the sea area,support self activation of drowning,and an ultra long endurance time of 72 hours.A simple installation type buckle structure has been designed to achieve stable installation of intelligent alarm terminals on traditional life jackets;we have developed a maritime rescue management system and related mobile apps.When an alarm occurs,it can display the precise positioning and time of the person falling into the water in real-time based on the intelligent alarm terminal information,helping rescue teams implement linear and precise search and rescue.The demonstration application of intelligent alarm life jackets was carried out at four fishing ports in Guangdong Province,including Hengshan Fishing Port in Taishan City,Jiazi Fishing Port in Shanwei City,Dayawan Fishing Port in Huizhou City,and Hongwan Fishing Port in Zhuhai City.A personnel drowning danger drill was completed at Lianhuashan Fishing Port in Panyu,Guangzhou.The developed intelligent alarm terminal and maritime rescue management system provided technical support for the above activities and received unanimous praise from users.
