Life-saving Tube Device and Control Method thereof

摘要

The present invention relates to a life-saving tube device and a control method thereof which shorten rescue time. The life-saving tube device comprises: a chamber housing which is installed on an underwater bottom surface, has a space formed therein, and includes a door whose upper portion is opened and closed; a pressure tank which is installed in the chamber housing, and supplies compressed air into a tube; a control unit to receive a rip current occurrence signal from a monitoring unit to control a valve which opens and closes the pressure tank; and a tube inserted into the chamber housing in a contracted state, and filled with air if a prescribed condition is satisfied to float by buoyancy. The life-saving tube device is operated by sequentially undergoing: a door opening step in which the control unit receiving the rip current occurrence signal opens the upper portion of the chamber housing; a pressure tank opening step in which the control unit receiving the rip current occurrence signal opens a first valve connected to the pressure tank; a tube expanding and floating step in which compressed air is injected into the tube by the pressure tank opening step to rapidly expand the tube to allow the tube to float to the water surface; an air pump operating step in which the control unit receiving a situation end signal drives an air pump after a prescribed period of time; an air discharge step in which air in the tube is removed by the air pump driving step; a winding step in which the control unit drives a winding means to wind a supply hose when the air in the tube is removed by the air discharge step; and a door closing step in which the upper portion of the chamber housing is closed by a signal of the control unit after the supply hose is wound by the winding step.
