The present invention relates to an electronic ship delivery method and system for ports and narrow waterways, and more specifically to the ground control center, such as reporting information, weather information, maritime information, construction status, ship density of ships operating in the control area Electronic ship delivery method and system for harbor and narrow waterway that can promote safe and safe operation of ships operating in harbor and narrow waterway by providing comprehensive navigation information to ships operating in control area will be.

Electronic Chart Display and Information System (ECDIS), Automatic Identification System (AIS), Global Positioning System (GPS Plotter) And various types of systems such as radar.

In general, an electronic navigation chart (ENC) is used as a digital chart for electronic navigation equipment used for various vessels through digitalization of paper charts to protect the navigational safety of the ship and the marine environment. By using the electronic chart, the position, speed, route, direction, and position of other ships are displayed on the computer screen, and when a dangerous situation or a collision with another ship occurs, By preventing accidents, the navigator can operate the ship much more safely than when using paper charts. The emergence of electronic charts further enhances the level of safe operation, protecting valuable lives and property at sea, preventing pollution and protecting the environment, and more efficiently and efficiently through efficient navigation management. It became.

These electronic charts not only support the intelligent navigation support system called ECDIS, a new navigational resource that can take the level of safe operation, environmental protection and logistics to the next level, but also the Vessel Traffic Control System (VTS). It is already widely used as the base map for the Traffic Service (VMS), Vessel Monitoring System (Vehicle Monitoring System), and Route Sign Intensity Management System. In particular, the International Maritime Organization (IMO) recommends the use of such electronic charts through Chapter 5 of the Safety of Life at Sea (SOLAS) Regulations in 1974, and the International Hydrographic Organization (IHO) standardizes them. -57 (production and distribution of the electronic chart) and S-52 (display of the electronic chart) were established. The ECDIS provided that the vessel be able to be placed on board a ship only after passing the performance standard of IEC 61174. For example, national waterway bureaus have the right and responsibility to produce and distribute certified electronic charts in accordance with the S-57 standard in the coastal survey of their coasts. Electronic charts are produced and supplied. In particular, SOLAS ships engaged in international navigation of 500 tons or more are recommended to use the international sea chart as a substitute for the paper duty on paper charts, but the sea charts of sea charts in sea transportation are recommended. As utility and functionality are demonstrated, their use is spreading day by day. Almost all new ships are equipped with an electronic chart information system, and many shipping companies plan to mount the system on existing ships. In addition, there is a movement to enforce the use of electronic charts in order to protect specially managed areas such as narrow channels and canals in a particular sea area from pollution and accidents, and the future is likely to be mandatory equipment such as radar or gyro.

However, because the S-57-based electronic charts are set high so that they are suitable for the navigation of large-scale ships of a certain size and are engaged in international navigation, the contents are diverse and the data level is deep. It requires relatively high performance and expensive ECDIS equipment. In addition, sailing for the journey from the origin to the destination has been established and manufactured as a main purpose. For example, small fishing boats intended for offshore operations are not practically helpful, Inadequate in quality In addition, considering the economic factors to introduce expensive equipment, it does not correspond significantly to the usefulness and efficiency. Other special ships, such as survey ships for surveying and exploration, fishing guide ships for guiding fishing, navy and maritime patrol boats for sea area monitoring, are not suitable for the purpose of operation of the ship, even if they meet the international standards. There are many. In particular, since more than 70% of coastal accidents are related to small ships, these small ships need more electronic sea charts for maritime safety and environmental protection.

Generally, it does not meet the performance standards of the S-57 international standard, but its own equipment that digitizes paper charts and runs on computers is called ECS (Electronic Chart System). In other words, it is a simple electronic chart information system that does not meet the performance standards of ECDIS that operates S-57-based public charts. Small fishing boats, coastal passenger ships and other special purpose ships require ECS that is economical and compliant for navigation purposes, rather than expensive, high-performance ECDIS equipment. In Korea, it is widely used in fishing vessels and offshore tankers under the name of GPS Plotter. The equipment, which was considered to have been activated after the Gulf War in 1991, was initially used by scanning the coastal charts of the domestic coast into a GPS Plotter, which was introduced in Japan, and required to submit track records for offshore tankers for marine pollution and disaster prevention. It was rapidly spread in the wake of the government's efforts to subsidize the purchase and to support fishing. Currently, about 30,000 ships use this equipment, and the Ministry of Maritime Affairs and Fisheries plans to enact GPS navigation equipment for cargo ships with more than 30 tons of fishing vessels and 150 tons of cargo ships, 80% of registered vessels. The use of this equipment is expected to spread to Korea, which is a non-SOLAS ship (less than 500 tons).

However, the charts used in the simple chart display system such as GPS Plotter using satellites are non-standard digital charts developed by commercial companies and commercially manufactured by equipment companies without specialized technical personnel. As a result, there is a lack of confidence in accuracy, and since each company manufactures a separate format and information, the user's confusion is increasing, and since it does not accept the latest chart information, there is a high risk of accidents. In fact, stranding incidents caused by navigation of automatic vessel position indicators using inadequate satellites, missing indications of dangerous goods, geodetic errors, and errors in signal indications from satellite navigation systems have not been lost. Therefore, there is a demand for the development of a device capable of providing accurate charts and appropriate updates in coastal voyage where real-time acquisition of information is key, and obtaining information between ships at the same time.

On the other hand, the Republic of Korea Patent Publication No. 10-0404428 "artificial intelligent maritime alarm system" is commercialized by installing the position information of the operating vessels measured by real-time satellite navigation equipment (GPS) and the operation information of the vessel on the vessel Real-time monitoring of the routes of ships in all sea areas collected and collected at the central control station on land using various kinds of wireless data communication networks, and improved by the registered ship's specification and operation information database system, maritime safety engineering and artificial intelligence techniques The accidents derived from the results of the analysis based on the artificial intelligence ship position prediction system and the collision prevention support system, and the stranding analysis and prevention function through the sea area and obstacle comparison system using the position of the ship and the electronic chart (ECDIS) The expected route and the accident avoidance route of the high risk vessel are returned to the vessel. Advance notice of data communications equipment, or other conventional control method has been proposed a technique to prevent large accidents.

In addition, the Republic of Korea Patent Publication No. 10-0433258 "Web service method for the safe operation and control of the vessel" is receiving the electronic chart data and ship safety navigation-related information to the ECS terminal for ships through wireless communication and the position of the ship And other information to a specific user through the Internet, the ASP system consists of a safe flight management server and related data databases, and a safe flight management server manages all data used for safe flight and control, and provides users with services over the Internet. The related data database consists of the electronic chart database, user profile, ship database, marine environment database, and user storage space.The ship's navigator is provided with real-time ship safety information such as the latest electronic chart and current weather environment. Their location information via the Internet So where it eseona receive government services in the same period of Marine Police can confirm whether or not the compliance of each ship offers a variety of services to specific users because it proposes a technology that allows you to control the safety of ships and sailing vessels.

However, such a conventional technique basically uses an electronic chart information system (ECDIS), an automatic ship identification system (AIS), a GPS automatic positioning device (GPS Plotter) and a radar based on an electronic chart on a ship. There is a problem that can only be made in support of the navigation system.
