DETAILED DESCRIPTION The following detailed description, together with the accompanying drawings, is intended to describe exemplary embodiments of the present invention, and is not intended to represent the only embodiments in which the present invention may be practiced.

In the drawings, parts unrelated to the description may be omitted to clearly describe the present invention, and the same reference numerals may be used for the same or similar elements throughout the specification.

In an embodiment of the present invention, expressions such as “or”, “at least one”, etc. may represent one of the words listed together, or a combination of two or more.

1 is a view showing the configuration of a route optimization system of a ship according to an embodiment of the present invention.

Referring to FIG. 1, the route optimization system of the ship of the present invention may include a route providing device 100 and a management server 200.

The route providing device 100 is provided on a ship, and can predict and search for an optimal route in consideration of a route to a destination, speed, expected arrival time, or fuel efficiency.

At this time, the route providing device 100 predicts a weather condition to a destination and a degree of coastal congestion of the destination, based on weather information, ship overcrowding area information, ship location information for each region, or cumulative operation data of the ship, and predicts the weather condition. And it may reflect and provide at least one of the degree of coastal congestion to search for and provide the optimal route to the destination.

As an example, the vessel location information for each region may include region-specific AIS (Auto Identification System) information.

Specifically, the route providing device 100 stores the communication unit 110 for communication with the outside, route map information including weather information and ship overcrowded area information, ship location information for each region, or cumulative operation data of the ship. Based on the information stored in the memory unit 120 and the memory unit 120, the weather condition and the degree of coastal congestion of the destination are predicted, and the optimal route to the destination is searched by reflecting at least one of the predicted weather condition and the degree of coastal congestion It may include a route search unit 130 and an information providing unit 140 that displays and provides the optimal route searched by the route search unit 130.

Here, the memory unit 120 stores a weather information database 121 in which weather information such as real-time weather forecasts and past weather accumulation data is stored, and a route map including routes to destinations and vessel dense area information for each area. It may include a map database 122, location information database 123 for storing location information of ships by region, and operation information database 124 for storing accumulated operation data of ships.

At this time, the weather information database 121 may store real-time weather forecasts including atmospheric conditions, wave heights, wave periods, wave directions, wind speeds, or wind directions, and cumulative weather data for each period (eg, by month, by date).

In addition, the location information database 123 may store ship location information including information such as the type of ship operating the destination coast, location, or ship speed.

In addition, the actual flight data of the ship is stored in the flight information database 124, and the accumulated real flight data may include ship speed measurement data for each latitude / longitude.

Here, weather information stored in the memory unit 120 and ship location information for each region may be periodically received and stored from the management server 200 to be described later.

In addition, the route search unit 130 first searches for a route that can reach the destination using a minimum amount of fuel within a predetermined time according to the driving specification of the ship and the input destination, and then the weather information stored in the memory unit 120 Optimal route considering weather conditions to destination and degree of congestion at destination coast by predicting and reflecting weather conditions and degree of coastal congestion at destination, based on vessel overcrowding area information, ship location information by region, or cumulative operation data of ship You can browse.

That is, in the case of a route searched considering only the driving specification of the ship or the input destination, various variables can occur depending on the weather conditions or the degree of congestion on the coast of the destination, so errors in the estimated estimated time of arrival or the amount of fuel used to reach the destination Although it may occur largely, as described above, in the case of the route searched in consideration of the weather condition and the degree of congestion on the coast of the destination, it is possible to more accurately predict the estimated time of arrival to the destination or the amount of fuel used.

Specifically, the route search unit 130 may calculate and predict the weather condition and the degree of coastal congestion of the destination as the probability of occurrence, and calculate and search the optimal route to the destination reflecting the predicted weather condition and the degree of coastal congestion as the probability of occurrence can do.

In addition, the route search unit 130 receives the estimated time of arrival or the amount of used fuel of the vessel outside the destination from the user, and arrives at the expected time of arrival to the destination or arrives using the input amount of used fuel You can calculate and search.

At this time, as mentioned above, in the process of calculating and searching for the optimal route, the predicted weather condition and the degree of coastal congestion as the probability of occurrence may be reflected.

Thereafter, the route search unit 130 may perform reliability verification of the calculated and searched optimal route.

Specifically, the optimal route taking into account the estimated time of arrival or the amount of used fuel of the corresponding vessel input by the user is the probability of the expected time of arrival or the amount of fuel used, etc., due to the reflection of weather conditions and coastal congestion predicted as occurrence probability It can be provided in the form of a density function.

For example, when calculating and searching for an optimal route from Incheon to Busan that can arrive after 8 hours, due to the reflection of the predicted weather condition and coastal congestion as the probability of occurrence, the expected arrival time for the same route is 8 hours As shown in the following, it is not specified as a single value, but has a distribution of a plurality of values, such as after 7 hours, after 8 hours, and after 10 hours.

Consequently, the distribution of the plurality of values can be expressed in the form of a probability density function.

The route search unit 130 may perform reliability verification by checking whether a probability density function such as an expected arrival time or a fuel amount is within a predetermined reliability range or a reliability range input by a user.

For example, for a probability density function in which the estimated time of arrival is 8 hours later, a reliability range in which a cumulative probability value of up to 8 hours (eg, 7 hours, 7 hours, 30 minutes, etc.) is preset or a reliability range input by the user In the case of 95% phosphorus, the reliability of the calculated and searched optimal route can be affirmed, and the optimal route can be determined.

On the other hand, if the accumulated probability value does not reach the preset reliability range or 95%, which is the reliability range input by the user (e.g., when there are multiple distributions of 8 hours, 30 minutes, 9 hours, etc.), operating conditions are changed. Thus, a new optimal route can be calculated and searched, and it can be repeated until the reliability range is satisfied.

On the other hand, if it is impossible to provide the optimal route according to the expected arrival time or the amount of used fuel input by the user through repeated calculation and search, the user is notified that the optimal route cannot be provided, and optionally the expected arrival time or use It is possible to calculate and search the optimal route excluding fuel amount and provide it to the user.

In addition, the information providing unit 140 is composed of display means such as a display, and may display and provide an optimal route searched through the route search unit 130.

Meanwhile, as described above, the management server 200 may communicate with the route providing device 100 to provide weather information and ship location information for each region to the route providing device 100.

Specifically, the management server 200 may collect weather information from a weather control center, and collect location information of ships operating a corresponding region from a base station that identifies the location of the ship for each region, and ships the collected information. It can be periodically transmitted to the route providing apparatus 100 provided in the.

That is, the route providing device 100 searches for a route that can reach a destination using a minimum amount of fuel within a predetermined arrival time. At this time, the cumulative operation data of the corresponding vessel stored in the ship and map-based vessel overcrowding area information and In addition, it is possible to search for a route by additionally utilizing weather information, such as real-time weather forecast and past weather accumulation data provided from the management server 200, and location information of a ship operating the destination coast.

In addition, the management server 200 receives terminal reservation information, including terminal reservation information of a terminal entering a destination (e.g., a port), a terminal usage status according to a passenger's embarkation, and a terminal usage status according to cargo unloading, and the like. It may be provided to the route providing device 100.

That is, even if the ship arrives at the destination, if the port needs to wait for arrival, boarding or unloading depending on the terminal status, the actual arrival time may be delayed. Accordingly, in the process of searching for the optimal route, provided by the management server 200 By reflecting the information on the terminal congestion level of the corresponding destination, it is possible to search for an optimal route taking into account the arrival time of the ship, the arrival and departure time of the passenger or the unloading time of the cargo.

On the other hand, hereinafter, with reference to the accompanying drawings, a method for providing an optimal route using a route optimization system of a vessel according to an embodiment of the present invention having the above-described configuration will be described.

FIG. 2 sequentially shows a method for providing an optimal route according to an embodiment of the present invention, and FIG. 3 predicts and reflects a process of predicting and reflecting a weather condition according to an embodiment of the present invention, and a degree of coastal congestion at a destination. It shows the process.

Referring to FIG. 2, an optimal route providing method according to an embodiment of the present invention includes receiving a destination (S110), searching for a route to the received destination (S120), weather information, vessel overcrowding area information , Predicting the weather conditions and the degree of coastal congestion of the destination based on the location information of the ships or cumulative operation data of the vessel, and searching for an optimal route to the destination by reflecting at least one of the predicted weather conditions and the degree of coastal congestion (S130) and outputting the searched optimal route (S140).

Specifically, when a destination is input to the route providing device 100 (S110), the route providing device 100 searches for a route to the received destination (S120).

In addition, based on weather information stored in the memory unit 120, vessel overcrowded area information, ship location information for each region, or cumulative operation data of the ship, the weather condition to the destination and the degree of congestion at the coast are predicted, and in the course of the course search, By searching by reflecting at least one of the predicted weather conditions and the degree of coastal congestion, an optimal route to a destination may be searched (S130).

At this time, in the process of predicting and reflecting the weather condition to the destination, as shown in (a) of FIG. 3, real-time weather forecast and periods including atmospheric conditions, wave height, wave period, wave direction, wind speed or wind direction, etc. (E.g., monthly, by date) Using weather accumulation data, real-time weather forecast data according to the region and date where the vessel is located and past weather accumulation data can be calculated by linking to predict the weather status to the destination ( S210), the predicted weather condition can be applied as a variable and reflected in the searched route (S220).

In addition, in the process of predicting and reflecting the degree of coastal congestion at the destination, as shown in (b) of FIG. 3, vessel overcrowded area information, location information of each ship, specifically, location information of a ship operating the destination coast and Using ship's cumulative operation data, the number of ships per unit area on the coast of the destination and the ship's predicted value, and the ship's ship speed measurement data by latitude and longitude through the cumulative operation data are derived and calculated in conjunction to calculate the coastal congestion of destination The degree of accuracy can be predicted (S310), and the ship speed at the coast of the destination can be checked through the predicted degree of coastal congestion, and the degree of coastal congestion of the predicted destination can be applied as a variable and reflected in the searched route ( S320).

Also, although not shown, information on terminal congestion is received and searched, including terminal reservation information of a terminal entering a destination (for example, a port), terminal usage status for passenger boarding and terminal usage status for cargo unloading, etc. It can also be reflected in the path.

That is, even if the ship arrives at the destination, if the port needs to wait for entry, embarkation or unloading depending on the terminal status, the actual arrival time may be delayed. Accordingly, in the process of searching for the optimal route, provided by the management server 200 By reflecting the information on the terminal congestion level of the corresponding destination, it is possible to search for an optimal route taking into account the arrival time of the ship, the arrival and departure time of the passenger or the unloading time of the cargo.

As described above, when the predicted weather conditions and the degree of coastal congestion are reflected in the initial search route, the accuracy of information about the expected arrival time can be increased, and the arrival at the destination is substantially faster (eg, passenger disembarkation time, cargo unloading time) ) To provide the optimal route.

Meanwhile, when the optimal route to the destination is searched, the optimal route may be output and provided through the information providing unit 140 provided in the route providing device 100 (S140).

4 sequentially shows a method for providing an optimal route according to another embodiment of the present invention.

Referring to FIG. 4, a method for providing an optimal route according to another embodiment of the present invention includes receiving a destination and an estimated time of arrival or a fuel amount (S410), and searching for a route to the received destination (S420). Based on weather information, vessel overcrowded area information, ship location information for each region, or cumulative operation data of a ship, the weather condition and the degree of coastal congestion of the destination are predicted, and at least one of the predicted weather condition and the degree of coastal congestion is reflected, Searching for an optimal route that can arrive at the input expected arrival time to the destination or arrive using the input fuel amount (S430), verifying the reliability of the searched optimal route (S440) and verifying the optimal route It may include the step of outputting (S450).

Hereinafter, a detailed implementation method is similar to a method for providing an optimal route according to an embodiment of FIG. 2, and the difference from the method for providing an optimal route according to an embodiment of FIG. 2 will be mainly described.

When the destination and the estimated time of arrival or the amount of used fuel are input to the route providing device 100 (S410), the route to the received destination is searched (S420), and the predicted weather condition and the degree of coastal congestion of the destination are reflected as the probability of occurrence. By doing so, it is possible to calculate and search for an optimal route that can arrive at the expected time of arrival to the destination or by using the amount of fuel used (S430).

On the other hand, in this embodiment, the route search process is described in two steps, but the present invention is not limited thereto, and as a first step, the route is searched by reflecting the predicted weather condition and the degree of congestion on the coast of the destination from the beginning. It is obvious that it can.

Thereafter, reliability verification is performed on the optimal route calculated and searched (S440), and a reliability range (for example, 95%) or a reliability input by a user, in particular, a probability density function of an expected arrival time or a fuel amount is set. Reliability verification can be performed by making sure it is within range.

For example, for a probability density function with 80 fuel consumption, a cumulative value of 80 or less (eg, 70, 75, 79, etc.) satisfies a predetermined reliability range of 95% or a reliability range input by the user. In this case, the reliability of the calculated and searched optimal route can be affirmed, and the optimal route can be determined and output (S450).

However, if the accumulated value does not reach the preset reliability range of 95% or the user-supplied reliability range (for example, when there are a large number of distributions such as 85, 86, 95, etc.), operation is performed until the reliability range is satisfied. By changing conditions, etc., it is possible to repeat the process of calculating and searching the optimal route.

On the other hand, if the iterative process exceeds a preset range, the user is notified that the route is not provided to the destination according to the corresponding condition, that is, the estimated time of arrival or the amount of fuel used by the user, and optionally, the user inputs The optimal route excluding the estimated time of arrival or the amount of used fuel can be calculated and searched and provided to the user.

As described above, a route optimization system of a ship and a method of providing an optimal route using the ship according to an embodiment of the present invention include weather information, ship overcrowding area information, ship location information by region, and ship in the process of searching for a route to a set destination. By predicting the weather condition to the destination and the degree of coastal congestion of the destination based on the cumulative flight data, etc. of the destination, it is planned to arrive at the destination by searching for and providing an optimal route reflecting at least one of the predicted weather condition and the degree of coastal congestion It is possible to more accurately predict the time and the amount of fuel used, and shorten the actual arrival time of the ship based on the time when the passenger or cargo unloading or unloading is started, not simply the time when the ship arrives at the destination.

The embodiments of the present invention disclosed in the present specification and drawings are merely to provide a specific example to easily explain the technical content of the present invention and to understand the present invention, and are not intended to limit the scope of the present invention.

Therefore, the scope of the present invention should be interpreted to include all the modified or modified forms derived on the basis of the technical spirit of the present invention in addition to the embodiments disclosed herein.
