Ocean black box surveilance device for standard-type of light bouy

The present invention relates to a marine black box monitoring device for a standard type light buoy, and more particularly, it is designed to be easily mounted on the top of a standard type LED light buoy, and can be mounted on a standard type light buoy, thereby reducing the possibility of collision by an external vessel and having a camera, embedded A standard type light buoy that includes an anti-immersion housing for Linux and smart modules, and applies Iridium Modem to enable supply of captured image data at high transmission speed and supports shooting in at least 5 directions It relates to the marine black box monitoring device for the dragon.

Recently, the marine environment and climate are rapidly changing due to global warming, but data collection for monitoring and predicting changes in the marine environment is very insufficient. In particular, social and economic losses are occurring due to various marine accidents such as the Dolphin Accident, the Sewol Ferry accident, and damage from rust/red tide, and the public's interest in disaster safety is increasing, but special and specific measures for marine safety are insufficient. am.

Republic of Korea Patent Publication No. 10-2004-27524 discloses a buoy for ocean observation. The buoy for ocean observation according to the disclosed patent includes a seawater measuring device that detects and collects floating objects floating on the sea level and the state of seawater, is connected to the seawater measuring device to receive data, and uses a wireless communication network to exchange collected data to a remote location. It consists of a repeater, and a solar power supply that supplies power to the seawater meter and the wireless repeater.

Although there is still a need for development of an integrated marine sensing system that can monitor disaster safety, marine weather, and the marine environment in real time, in particular, in the case of ocean observation devices in the wave height field, expensive foreign equipment is mainly used. . A marine monitoring system using a standard type light buoy is not being applied in the world, but if a marine monitoring system using a standard type light buoy is applied, it will be possible to secure quality and price competitiveness by reducing the cost of introduction and maintenance.

There are about 4,000 standard light buoys installed in Korea, and if they are designed to detect disasters safely, it will not only create a new market but also greatly contribute to the substitution of foreign products.

On the other hand, Article 3 of the Enforcement Regulations of the Air Route Marking Act stipulates the types of navigational signs. Types of navigational signs include 1. Light wave signs: manned lighthouse, unmanned lighthouse, beacon, road light, survey light, direction light, light pole, bridge, etc. , traffic lights, light buoys, spar buoys, LANBYs, and lightsabers, 2. Shape signs: standing signs, diagrams, bridge tables, traffic signs and buoys, 3. Sound wave signs: Electric horn, air siren, motor siren and diaphone, 4. Radio beacon: radar beacon, loran, satellite navigation correction system (DGNSS) and radar station, 5. special signal beacon: tide signal beacon, marine weather signal beacon and Automatic Position Identification Signal Sign (AIS), and the route signs in Nos. 1 to 4 are signs for construction purposes, signs for sunken/stranded ships, signs for bridges, mooring signs, submarine cable signs, It can be divided into subsea pipeline signs, marine data collection signs, marine resource exploration signs, marine resource drilling signs, or special route signs for marine resource mining.

As of 2016, 4,800 such navigational markers, such as buoys, are installed in Korea, but as shown in FIG. 1, the objects are often damaged as shown in FIG. When it is damaged by a running vessel, the wind direction and/or wind speed sensor is broken and observation data is not received, so the possibility of damage can be known. Theft of the buoy platform is also taking place.

The technical problem to be achieved by the present invention is that by using standard light buoys, not only can quality and price competitiveness be secured by reducing introduction and maintenance costs, but also the possibility of buoy damage is increased, and any of the theft or malicious behavior of the buoy can be detected in real time. It is to provide a standard marine black box monitoring device for light buoys that can be monitored.

The marine black box monitoring device for a standard type light buoy according to the present invention can not only secure quality and price competitiveness by reducing introduction and maintenance costs by using a standard type light buoy, but also increase the possibility of buoy damage and theft or malicious behavior of the buoy can be monitored in real time.

The real-time location-based standard-type marine monitoring system for light buoys according to the present invention can secure quality and price competitiveness by reducing introduction and maintenance costs by using standard-type light buoys for ocean observation devices in the wave height field.

Hereinafter, embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

3 is a block diagram showing the structure of the black box device applied to the marine black box monitoring device for a standard light buoy according to an embodiment of the present invention. Referring to FIG. 3 , the black box device unit applied to the standard type marine black box monitoring device for light buoys according to an embodiment of the present invention supports a CMOS image sensor module supporting a resolution of 640 × 480 or 1,280 × 1024 pixels, and USB communication It has a TRITRON-C module, a memory module, a microcomputer, a collision detection sensor, an RS-232 module, and a power converter (DC/DC).

4 is a block diagram showing the configuration of a camera unit and a modem/battery unit as a configuration example of FIG. 3 . Referring to FIG. 4 , the camera unit provides a captured image to the modem/battery unit, and the modem/battery unit transmits the captured image and provides power to the camera unit. Iridium Modem supports the speed of 300 bytes per second, so it is possible to transmit a 400 KB image in about 2 minutes, and you can send photos anywhere in the world.

In addition, the camera unit consists of 5 cameras and is operated based on a Linux™ system, which reduces time by supplying power by the SB-900 smart module developed by the present applicant. Since the SB-900 smart module developed by the present applicant is driven with low power, it can be used in a harsh environment where a separate power supply is impossible. It also supports wireless networking, a 32GB file system, two way Iridium short burst, and an RS-232 serial port, GPS, and analog ports.
