Smart buoy system with function of preventing risks due to urban flooding

Abstract

A smart buoy system with a function of preventing risks due to urban flooding is proposed. The smart buoy system is provided with floating assemblies installed on fences on both sides of a road or fences on both sides of an underpass, and includes a plurality of base frames installed at positions spaced apart from each other on one side of a road, a floating assembly installed on each base frame so as to be movable up and down and including a plurality of buoys floatable on the water, a sensing unit installed on one side of the floating assembly or one side of each base frame and for generating sensed information, and a controller for generating road condition information on the basis of the sensed information received from the sensing unit and transmitting the generated road condition information to a preset external server or an external terminal.

What is claimed is: 
     
         1 . A smart buoy system, comprising:
 a plurality of base frames installed at positions spaced apart from each other on one side of a road;   a floating assembly installed on each base frame so as to be movable up and down and comprising a plurality of buoys floatable on the water;   a sensing unit installed on one side of the floating assembly or one side of each base frame and for generating sensed information; and   a controller for generating road condition information on the basis of the sensed information received from the sensing unit and transmitting the generated road condition information to a preset external server or an external terminal.   
     
     
         2 . The smart buoy system of  claim 1 , wherein the sensing unit comprises at least one among a water level sensor for detecting a water level of the road equipped therewith, a temperature sensor for detecting a temperature of a location equipped therewith, a flood sensor for detecting whether the road is flooded or not, and a thermal sensor for detecting heat in a setting area, and
 the road condition information comprises water level information, temperature information, flooding information, and heat detection information about the location equipped with the sensing unit.   
     
     
         3 . The smart buoy system of  claim 2 , wherein each sensor comprised in the sensing unit performs BLE communication with the controller, and
 each sensor is connected to the controller through a Bluetooth mesh network and transmits the sensed information to the controller.   
     
     
         4 . The smart buoy system of  claim 1 , wherein the floating assembly comprises:
 a lifting and lowering main body installed in a horizontal direction between a pair of vertical frames comprised in each base frame so as to be liftable and lowerable; and   a plurality of floating bodies connected to each other, installed in the lifting and lowering main body, and configured to float on the water when the road is flooded so as to lift and lower the lifting and lowering main body.   
     
     
         5 . The smart buoy system of  claim 4 , wherein the lifting and lowering main body comprises:
 a horizontal body provided with an LED unit installed thereon for blinking under a control of the controller, formed in the horizontal direction to have a predetermined accommodation space on a lower side thereof, and configured to accommodate each floating body; and   a pair of elevating bodies each having one side thereof connected to a rail groove that is in a vertical direction within each of the vertical frames facing each other, the pair of elevating bodies being connected to each other to be liftable and lowerable along each rail groove and receiving respective opposite end sides of the horizontal body.
