Description

Technology Field

Background Technology

[0003] Typically, a buoy is a device that floats on the water surface to indicate shipping lanes or mark danger zones within a port's controlled waters; it is formed with a specific color or shape to enable identification during the day and is equipped with lighting to allow for visibility by light at night.

[0004] Furthermore, driven by the need to utilize buoys efficiently, buoys equipped with various functions—such as navigation guidance and danger zone indication—have recently been developed and are in operation. In particular, marine observation buoys operated by agencies like the Korea Meteorological Administration and the Ministry of Oceans and Fisheries for the collection of maritime weather observations and environmental information are equipped with expensive equipment, including wind direction and speed sensors and superstructures.

[0005] To operate such onboard equipment, power was stored in lead-acid batteries or lithium batteries; however, lead-acid batteries have a high proportion of environmental pollutants, and lithium batteries are high-density batteries that pose a high risk for use at sea, so their use is being excluded.

[0006] Accordingly, technology is required to apply eco-friendly power storage media to the system that can minimize marine environmental pollution and reduce risk. Prior art literature

[0030] Hereinafter, with reference to FIGS. 1 to 7, a linear type lidar buoy for ocean observation equipped with a hybrid power supply system of the above-described configuration will be specifically described as follows.

[0032] First, the hull (110) is configured as a linear type, and with reference to FIGS. 1 and FIGS. 2, it consists of a lower hull (111) formed in a streamlined shape and an upper hull (112) equipped with a deck.

[0033] Here, a mooring device (113) for positioning the hull (110) within a certain area at sea may be formed at the lower end of the lower hull (111).

[0035] Next, the sensor unit (120), with reference to FIGS. 1 to 3, is equipped with a LiDAR sensor (121) positioned on the upper part of the upper hull (112) to measure wind conditions such as wind direction and wind volume, and an information processing module (122) that processes the wind condition information of the sea measured by the LiDAR sensor (121).

[0037] Next, the communication unit (130) wirelessly transmits wind condition information from the sensor unit (120) to a receiving unit on land. Referring to FIG. 3, it may include an iridium LTE router and an inmarsat LTE modem.

[0039] Next, the first power generation unit (140), with reference to FIGS. 1 to 3, is composed of a wind turbine (141) formed on each side of the rear end of the upper hull (112), a solar panel (142) formed on each side of the front end of the upper hull (112), and a lead-acid battery (143).

[0040] Here, the first power generation unit (140) further includes a methanol fuel cell (not shown) that generates power using methanol fuel and a fuel tank that stores methanol fuel for one to two months of use, and the main control unit can operate the methanol fuel cell to replenish power when the power generated by the wind turbine (141) and the solar panel (142) is less than the usage amount.

[0041] Additionally, the wind turbine (141) is arranged symmetrically on the left and right to maintain the balance of the hull (110), and can generate power by wind speeds of 3 m / s or more and supplement the power generated by the solar panel (142) during the winter or rainy season.

[0042] Additionally, the wind turbine (141) is connected to the upper hull (112) via a rotary drive unit so as to be hinge-rotated to maintain an upright position or tilted at a certain angle and fixed, and the rotary drive unit can be controlled according to the environment of the sea or when moving to the sea, so that the wind turbine (141) can be raised upright or fixed lying down on the upper hull (122).

[0047] Additionally, a plurality of modular counterweights (154) may be arranged adjacent to the mounting bracket (152) at the lower center of the lower hull (111) to maintain the balance of the hull (110) more stably.

[0049] Next, the BMS (Battery Management System) power control unit (160), with reference to FIG. 3, is composed of a plurality of battery packs (161) that store power generated from a seawater secondary battery (153), a slave BMS (162) that performs balancing of each cell of the battery pack (161), a master BMS (163) that communicates with the slave BMS (162) to control charging and discharging to the battery pack (161), and a BMS charging / discharging module (164) that charges the battery pack (161) with power generated from a wind turbine (141) or power generated from a solar panel (142) and discharges the power stored in the battery pack (161).

[0057] For example, as illustrated in FIG. 3, the main control unit may optionally apply 24V power to the sensor unit (120) and communication unit (130) through the first charge / discharge unit (170) or the second charge / discharge unit (180), or apply 24V power from the BMS power control unit (160) to the sensor unit (120) and communication unit (130) through the opening and closing of the first switch (SW1) and the second switch (SW2).

[0059] Additionally, if a floating object approaching within a certain distance is identified through the lidar sensor (121) or ocean cam (191) and a risk of collision with the floating object is predicted, the aforementioned propulsion unit may be used to perform an evasive maneuver.

[0061] Meanwhile, referring to FIG. 3, it may further include an ocean cam (191) for marine observation that is positioned on the upper part of the upper hull (112) to photograph the surrounding area and transmit it to a receiving end on land via a communication unit (130), and a DCDC converter (192) that converts the power of the first charging / discharging unit (170) or the second charging / discharging unit (180) to 12V and applies it to the ocean cam (191).

[0063] Additionally, referring to FIGS. 5 and 6, an upper deck (202) is formed on the upper hull (112) and supported by a support (201) of a certain height, and a LiDAR sensor (121) may be placed on the upper deck (202). Solar panels (142) may be attached to both sides of the support (201), and a BMS power control unit (160) may be fixed in the inner space of the support (201) in the form of a waterproof box module so as not to be easily exposed to seawater, thereby minimizing corrosion.

[0065] Additionally, as shown in FIG. 3, it may further include a water quality sensor (211) for measuring the water quality of the water body, a sensor node (212) for transmitting the measured value from the water quality sensor (211) to a receiving end on land, and a communication module (213) composed of an IoT gateway and a hub.
