Sea transport by ship has been used since ancient times because it is the most effective means of transporting large quantities of cargo to their destinations at economical prices and is still the basis for supporting economic activity in the world. Efficiency in these maritime transports has been improved by the constant effort of skilled sailors or onshore supporters. In addition, we are making continuous efforts to optimize fuel consumption to reduce the emission of carbon dioxide, which is the main culprit of global warming, due to the depletion of resources.

In general, it is well known that man-machine interfaces are commonly used in manufacturing plants to communicate with various machines and workers, and the technology for controlling devices is already well established and applied. Large shipyards are producing highly automated intelligence ships using information technology, which is developing rapidly, and delivering them to customers. In other words, a system has been developed to inform the user of weather and maritime information such as wind and tidal currents, trends of other ships at risk of collision, and location of shallow coasts at risk of stranding.

The present invention obtains the optimum speed that can be operated most economically to the next destination by obtaining weather information, maritime information, ship position information, etc. from various information devices installed on the ship in real time and present the optimized speed Its purpose is to optimize fuel consumption by transmitting to engine control system in real time to maintain proper load / speed.

The present invention is based on NMEA0183 (National Maritime Electronics Association 0183) from various information devices installed on ships-wind / windometer, satellite navigation system, speedometer, radar, AIS (Automatic Identification System), gyro compass, etc. It collects the operational status of the ship in real time using the data format according to the standard, derives the optimal operational conditions in consideration of the collected operational status, and uses the communication protocol for the PLC (Programmable Logic Controller) of the industrial computer. It is characterized in that the engine load / speed can be automatically adjusted by transmitting to the ECS (Engine Control System).

In the present invention, by operating the optimum RPM in consideration of the operating conditions of the vessel to determine the load and speed of the engine by the subjective judgment of the ship and the captain who is the ship's practitioner and the management of the company's operation management department and public service department. At least 10% more fuel can be saved.

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

Figure 1 illustrates the operational concept of the flight instruction optimization system. After entering into a contract with the customer (ship owner or charter owner) to use the operation instruction optimization system, the standard information, route information, and route plan of the possessed vessel are intelligent after actual operation. It receives real-time operational status from various information devices of the ship, such as ECDIS, calculates the optimum operating conditions, transmits them to the engine control system, or finally controls the engine in the bridge room at the operator's discretion. Induce consumption.

2 is a block diagram showing a flight instruction optimization system according to the present invention. Referring to FIG. 2, the present invention consists of a computer system 100 for optimizing a flight instruction, in which an S / W is registered in an industrial computer in consideration of adverse marine conditions and inputted unique information of each ship. The industrial computer system 100 may include a database 170 and a database 170 for storing ship information 171, route information 172, flight planning information 173, and flight status information 174. The ship information management module 110 to manage and the module 120 to manage the route information, such as the navigation course, navigation distance, navigation distance, port distance, module 130 for managing the estimated time of arrival to the destination, collecting in real time Module 140 for deriving the optimum operating conditions that can reach the target time using the operating status information, the module 150 for controlling the optimized operating conditions through the engine control system, sea conditions, weather conditions, The module 160 is configured to collect necessary information for optimizing the operation instruction from the ship position information, speedometer and the like. The database 170 used in the system consists of the following information. The ship information 171 is basic information about the ship, and includes clear, dry date, last dock repair date, captain name, engineer name, first navigator name, minimum / maximum / economy RPM information. The route information 172 includes information such as a route code, route sequence, departure port, arrival port, departure-arrival port navigation distance, navigation distance, port distance, and the like. The flight planning information 173 includes the scheduled departure time, arrival arrival date, sailing distance, navigation distance, and port distance information with reference to the route code managed in the route information.

The unique information 171 of a specific ship is registered together when the operation instruction optimization program is installed in the industrial computer, and registers the corresponding route of the corresponding ship (S010). When the company decides the flight plan for the corresponding port of the vessel, it receives it, establishes the flight plan and registers it (S020) .When the actual flight starts, the necessary information is obtained from the various information equipment mounted on the ship according to the NMEA0183 data format. Collect (S030). By using the collected flight information in real time, it optimizes the operating conditions for optimal fuel consumption to the next destination (S040) .The optimized operating conditions are determined by using ECS (MODBUS), which is a protocol for the programmable logic controller (PLC) of industrial computers. Engine control system (S050).
