Description

Coastal Safety System Using Safety Buoys The present invention relates to a coastal safety system using a safety buoy, and more specifically, to a coastal safety system using a safety buoy that prevents safety accidents on the coast in advance. Generally, buoys are placed along the coastline to warn swimmers not to venture out to sea. These multiple buoys are connected by ropes to form a boundary. However, these buoys are made of styrofoam and float on the water surface so that users can use them like tubes, but the current reality is that they do not perform any function other than marking boundaries. Recently, safety accidents have been occurring where rip currents pull swimmers out to sea as water recedes from the shore. Additionally, as seawater warms and harmful marine creatures such as jellyfish and sharks appear at beaches, lifeguards are monitoring the beaches with increased vigilance; however, there is a problem in that there are limitations to monitoring the entire expansive beach. FIG. 1 is an exemplary diagram of a safety buoy unit and a floating body part deployed on a coast according to the present invention. Figure 2 is a control block diagram of a coastal safety system using a safety buoy, a safety buoy unit, and a danger detection server. FIG. 3 is a flowchart of a first embodiment of a method for providing coastal safety using a safety buoy using a coastal safety system using a safety buoy according to the present invention. Figure 4 is a flowchart of a second embodiment of a method for providing coastal safety using a safety buoy using a coastal safety system using a safety buoy.

FIG. 6 is a flowchart of the fourth embodiment of a method for providing coastal safety using a safety buoy using a coastal safety system using a safety buoy. Hereinafter, a coastal safety system (1) using a safety buoy according to a preferred embodiment of the present invention will be described in detail with reference to the attached drawings. FIG. 1 is an exemplary diagram of a safety buoy unit (10) and a floating body (11) deployed on the coast according to the present invention, and FIG. 2 is a control block diagram of a coastal safety system (1) using a safety buoy, a safety buoy unit (10), and a danger detection server (20). Referring to Figures 1 and 2, the configuration of a coastal safety system (1) using safety buoys is explained. A coastal safety system (1) using a safety buoy includes a safety buoy unit (10) and a danger detection server (20). The safety buoy unit (10) includes a floating body part (11), a communication part (12), a sensor part (13), an alarm part (14), a solar power generation panel (15), a power storage part (16), and a control part (17). The floating body part (11) includes a floating base (111), a floating housing (112), and a connecting link (113). The floating base (111) can be made of a floating body such as styrofoam and floats on the water surface. The floating housing (112) is combined with the floating base (111) that floats on the water surface to form an internal receiving space. The floating housing (112) is formed to be hermetically and watertightly combined with the floating base (111) so that water is not introduced into the internal receiving space. The connecting link (113) can allow multiple safety buoy units (10) to be connected by a rope. The communication unit (12) is positioned within the receiving space of the floating main body (11) and communicates with an external device. The communication unit (12) can perform wireless communication, and the wireless communication includes at least one of infrared communication, RF, Zigbee, and Bluetooth. The communication unit (12) receives a video signal and transmits it to the control unit (17) to be described later, and can be implemented in various ways corresponding to the specifications of the received video signal and the implementation form of the user terminal. For example, the communication unit (12) can wirelessly receive an RF (radio frequency) signal transmitted from a broadcasting station (not shown), or receive a video signal according to composite video, component video, super video, SCART, HDMI (high definition multimedia interface) specifications, etc. via a wired connection. If the video signal is a broadcast signal, the communication unit (12) may include a tuner that tunes the broadcast signal by channel. The sensor unit (13) includes a first camera (131), a second camera (132), an RF sensor (133), and an internal temperature sensor (134). The first camera (131) is supported on the upper side of the floating body part (111) and photographs the water surface. The second camera (132) is supported on the lower side of the floating body part (111) and films underwater. The RF sensor (133) is positioned on the upper and lower sides of the floating bo
