Description

Ship Collision Avoidance Device {DEVICE FOR PREVENTING SHIP CRASHING}

The present invention relates to an apparatus for preventing a collision of a ship at sea.

The present invention relates to a device for preventing collision between ships at sea, and most of the marine accidents occurring in Korea are caused by human error, and operate in external situations such as non-compliance of navigation, front boundary hole or weather. In many cases, accidents occur due to overlapping experiences, lack of awareness of the situation, and late coping. It's happening.

In order to prevent such accidents at sea, ship radars are usually used. Although ship radars generate warning signals when other ships come within a certain distance, they are not fully automated and the user can track among the various signs displayed on the radar screen. It only works if the ship is pinpointed, which inevitably depends on the user.

In addition, recently, automatic steering gears have been installed at high speeds and are often operated, causing crash accidents frequently. Tired of long life on ships and unreasonable work due to lack of work, many accidents have occurred.

Republic of Korea Patent Publication No. 10-1999-002635 'Ship steering device equipped with a collision avoidance function' is to prevent collisions around the ship to prevent accidental collisions with marine floats, reefs, other ships, etc. Collecting data of the elements and analyzing the collected data, if a collision is expected, a switching signal for switching the operation mode of the autopilot is sent to change the loader angle signal so that the collision can be avoided. However, since the data collection of the collision elements are to be collected using a chart or through a separate device, it is not very helpful when the data of the collision elements are not collected or inaccurate.

Republic of Korea Patent Publication No. 10-2004-0016956 'Ship Collision Prevention Alarm' is installed to connect the radar and the alarm mounted on the vessel and to drive the sensor according to the voltage and frequency of the radar device, the object according to the situation and needs We will calculate the proximity, shape, size, etc. and determine if the result is dangerous. This has the advantage of being compatible with a variety of radars, but it is a one-dimensional configuration because it allows the user to recognize danger through an alarm sound, and it is very difficult to obtain information about the proximity of an object or a ship.

At present, due to the technology that is controlled and managed in major ports, accidents can happen again at any time, and now, large and small accidents are continuously occurring not only in Korea but also abroad. Radar alone can cause accidents even if the waves are not visible due to heavy waves or fog, or if one of the vessels is not aware of them, even under the control of a third party.

In the past and recent years, marine pollution and ecosystem destruction caused by collisions between ships in the sea are frequently occurring, and there are always risks of collisions between ships in the sea. There are methods and laws, but most of them have to rely on the centrally controlled control system, and the central control system must fully control all these situations, and in the ranking of control, the ships loaded with large ships or dangerous goods are inevitable. Even a small ship, a private fishing boat or a central control system that controls all ships is not easy. The central control station should have manpower and equipment, and in the absence of small fish tanks or such control stations, there is a high risk of accidents and the responsibility for negligence in the event of an accident.

The present invention has been made to overcome the above-mentioned disadvantages, and an object of the present invention is to provide an apparatus for preventing collision of ships, which is simple in structure and inexpensive without being directly monitored by a person.

In order to achieve the above object, the present invention provides a ship collision prevention apparatus, the ship collision prevention apparatus

A GPS receiver for receiving a GPS satellite signal to determine the position of the ship;

A transmitter for transmitting vessel basic information including position information and speed information of the vessel received from the GPS receiver to a surrounding vessel; a receiver for receiving vessel basic information sent from another vessel; and the GPS receiver And a control unit controlling the operation of the bride and the receiver and extracting the ship position information centering on the vessel by combining the position information of the other ships received from the receiver.

 The receiver may include an antenna for base stations of the vessel, and the transmitter and receiver may transmit and receive data using any one of CDMA, FDMA, and TDMA, and include the location information in a synchronization signal.

It may further include a server transmission and reception unit for transmitting and receiving the vessel position information to the central control server by any one of a wireless network including a wireless communication network, a wireless telephone network.

 The vessel basic information may further include an identification code of the vessel.

The information transmitted by the transmitter may further include vessel position information calculated based on vessel basic information received from another vessel.

The invention as described above has the effect of preventing collision accidents between ships at sea.

Hereinafter, with reference to the accompanying drawings will be described in detail the present invention. 1 is a block diagram showing the concept of a ship collision prevention apparatus according to the present invention.

The GPS receiver receives data on the current position and speed from the GPS satellites.

The transmitter and the transmitter transmits a continuous signal to the outside, and the transmitted signal repeatedly transmits data about distance and data on identification of the corresponding ship (ship position, speed, etc.). The frequency to be used for transmission may be the frequency used in mobile communication, and the wireless access method also uses the frequency division multiple access method (FDMA), the time division multiple access method (TDMA), and the code division multiple access method used in the mobile communication method. CDMA) allows multiple users to communicate simultaneously, locate and process data in real time. Such a radio access method may use a method such as HSCSD, W-CDMA, IMT-2000, which is currently used or will be used in the future.

In addition, each ship should be equipped with a base transceiver station (BTS) equipment and equipment such as a base station controller (BSC) to enable the processing of such a radio access.

Using such equipment, each ship receives a signal transmitted from the surrounding ships, but each ship receives the location information received from the GPS sent from each ship. You will also be able to see how many ships are located around the ship. The coverage of a base station is usually about 0.5-35km, which may be greater than that given that it is at sea.

The ship's position is determined from the signals sent from each ship, which is displayed on the monitor's monitor, allowing the navigator to intuitively identify the hazard.

Equipment installed on the vessel can identify the position of the surrounding vessels around the vessel and also enable direct communication between vessels within the scope of the base station.

In addition, a separate server transmission and reception unit may be provided so that the existing wireless data network may be used, and the base station equipment of the ship may be connected to the existing wireless data network. To this end, as shown in FIG. 1, one or more transceivers may be used, but one transceiver may be used.

The display unit is composed of a data display device such as a monitor and displays the current position information of the ship and the surrounding sea area information.

The control unit controls the operation and data transmission of the memory and each transceiver.

In addition, the unique code number assigned to each ship at the time of data transmission is transmitted along with the ship's current position data and the ship's speed data obtained from the satellite, and the unique code number is a subscription number assigned to the ship on the base station. It may be. In each ship, even if communication is not carried out for each ship, the ship receives a signal from the ship to determine the ship's position.

In order to obtain detailed information of the vessel, the mobile communication network can be used to receive information about the subscriber and to receive additional information of the vessel. Through this information, the subscriber can be authenticated. However, since it is known from the ship's position information that is transmitted from the sea by the information transmitted from the ship, it is regarded as a valid transmission. In addition, by initiating a normal call (call) to send and receive data on the expected movement route, route can refer to the future direction of travel. This can also use technology related to wireless data transmission and reception of mobile phones.

The receiver receives the data sent from other ships, separates the data from the carrier, and displays the situation around the ship on a monitor based on the data sent from each ship. The receiver separates the position data from the unique code in the data contained in the synchronization signal sent by each transmitter.

In addition, such data may be transmitted to a central control server that collects ship's position data at a specific place through a mobile communication network such as wireless Internet, WCDMA, HSADPA, etc. to check the ship's movement status and predict the possibility of an accident.

The accident prediction can avoid the immediate danger by grasping the surrounding situation in each ship, but by sending the data of the ship to the central control server, the overall operation of the ship in each country can be immediately grasped and the management is easy. In particular, for ships that were previously difficult to manage, such as small ships, it is possible to determine whether the ship has not entered the restricted area or is in distress.

The communication with the central control server uses a mobile communication network. The mobile communication network is currently deployed in various countries of the world, and even if only in Korea, roaming service is available not only in the world, but also in the third generation communication network. This standardization eliminates the need for additional equipment.

Therefore, the communication between each ship within a certain area can be made according to the capacity of the base station of the corresponding ship, and the connection with the central control server can use the existing communication network can reduce the cost. Especially, the ship's certification data is not very large, and to prevent the ship collision, it is necessary to know where the ship is in the area where the ship is located, and to know the ship's location in other areas far away. This is because the existing mobile communication network can be used for communication.

The size of the data sent from the central control server is not very large, and the data sent from the central control server is sent by verifying the data sent from each ship, and the communication with the central control server because the primary risk is determined by each ship. Even if the existing mobile communication network is used, there is no problem.

In particular, in the present invention, the information on the operation of the ship centered on the relevant ship sends only the information about the location of the ship to the server, the server in charge of the central control grasped the location of all the ships to determine the risk Rather than sending the information back to the operating ship, the ship in operation grasps the operation status of other ships around it and sends this information to the server in charge of central control. The more places, the more accurate plural information about the ship's position, speed, etc. can be obtained.

It collects the primary data of the ship in operation and immediately judges the dangerous situation, and transmits the data on the location of other ships collected around this ship to the central control server as well. The server verifies the overall position of the ship, and based on this, it is determined whether the risk is comprehensive and transmitted to the ship to transmit the correct position data and determine the risk of this.

In particular, the information transmitted from a transmitter can obtain more accurate location information by transmitting not only the location information of its own but also the overall situation of the ship determined by the other ship and the picture of the ship.

In addition, when there are several ships, the ship can obtain information about the position of its own ship and other ships from several ships instead of one ship around it. It is possible to obtain the dangerous signal immediately and to send the aggregated information to the surrounding ships and the central control server. Vessels around them should immediately open a call to transmit data, and central control server to send information using the existing mobile communication network. Even if a call is not established, the ship's transmission information includes the location information, and each ship periodically transmits a location signal, so that each ship can grasp the position of the surrounding ship in real time. In cellular communication, information about the status of the mobile station, i.e. whether the power is turned off and the location of the mobile station, is important for making a call or receiving an incoming call. This is called location registration in order to reduce the system load and increase mobile station incoming signal reliability by informing the exchange from time to time.

When this location registration is carried out, it is possible to check the location information of the ship at the base station by transmitting the location information received from the GPS together.

In addition, in the case of the CDMA method, the mobile station turns off the hardware power of most functions except for the clock function except for a predetermined time, thereby reducing battery power consumption. The data of the call channel calling the mobile station from the base station is composed of slots of 80 msec units. The Taiwanese mobile station survives and checks to see if it is called.

This is called slot mode, and when the call channel is alive in slot mode, the base station (ship) can collect the ship's location information by transmitting the location information from the GPS.

In addition, since the information collected from several ships is primarily filtered, it is possible to obtain more accurate information, and each ship serves as a small control center. The central control server, on the other hand, verifies the ship's position and predicts the expected risks encountered during flight based on the ship's location information in a wider area. Since the data processing speed of the current PC is able to process this data in real time, it is possible to fully implement the processing information about each ship's driving information on each ship.

Radars, which are currently used in ships, are heavily influenced by the environment in the event of high waves or heavy fog, making it difficult to fully trust the data. Radio equipment used in ships can also be greatly affected by the environment, such as weather, so that carriers with long wavelengths can be used to transmit to surrounding vessels without being greatly affected by the weather. It is not a big problem even if the distance to be transmitted is not long because only the situation around each ship's own is known.

The central control server receives only the sea chart of the current sea area and displays it on the monitor using the location information received from the surrounding ships so that you can intuitively understand the danger situation. If you have a chart from you can get it immediately. In addition, it is possible to use the chart to find and guide the best route for the ship to travel.

Figure 2 shows an implementation system of the ship collision prevention apparatus according to the present invention. When there are several ships at sea, each ship transmits its location information, speed, and identification code so that ships in a certain area can share data about their location. The location information and identification code should be updated continuously, and when it is necessary to send and receive larger data, a call can be opened to send and receive data such as the route, the ship's position, etc. to avoid dangerous situations. In addition, each of these data is sent to the central control server to verify the data about each other's location and receive the hedging signal accordingly. The hedge signal may use an existing mobile communication network.
