Figure 2 is a flow chart for explaining the operation of the freshwater supply system using a seawater desalination vessel according to an embodiment of the present invention.

The present invention relates to a computer system for efficiently providing fresh water in providing fresh water to a plurality of islands through seawater desalination vessels.

In the present specification, the'seawater desalination ship' means a ship equipped with a seawater desalination device, and the seawater desalination device is a device that treats seawater to produce fresh water, as is well known. Furthermore, the meaning of'seawater desalination ship' in the present specification may be extended to a ship that operates by loading fresh water produced by a seawater desalination device. In other words, a ship that has a seawater desalination device installed to produce fresh water and moves it, a ship towing a ship with a seawater desalination device installed, and a ship that stores and operates only fresh water produced by the seawater desalination device is described in this specification as'seawater desalination. It corresponds to'ships'.

In addition, in the present invention, providing fresh water to a plurality of islands through a seawater desalination vessel means that the seawater desalination vessel provides freshwater produced by the seawater desalination vessel to each island via each island.

In order to efficiently perform the act of providing fresh water to a plurality of islands through seawater desalination vessels, it is necessary to identify islands requiring fresh water and to go through islands requiring fresh water as an optimal route.

More specifically, basic route information for passing through all of the plurality of islands subject to freshwater provision will be required, and real-time freshwater reserve information of each island will need to be reflected in order to set the optimal travel route, that is, the optimum freshwater supply route. . In other words, the optimal freshwater supply route should be established by reflecting the freshwater reserve information of each island in the basic route information. In addition, if an optimal freshwater supply route is established, the freshwater requirement required for the freshwater supply route can be calculated, and the freshwater requirement information of the freshwater supply route can be obtained so that the seawater desalination vessel can satisfy the freshwater supply route. Provided to desalination vessels, seawater desalination vessels must proceed with the production and retention of fresh water.

The information on the amount of fresh water required is shared with the seawater desalination vessel, and based on this, it can be said that it is the technical idea of the present invention to stably provide fresh water to a plurality of islands requiring fresh water through an optimal freshwater supply route.

Hereinafter, a freshwater supply system using a seawater desalination vessel according to an embodiment of the present invention will be described in detail with reference to the drawings.

Referring to FIG. 1, the freshwater supply system using a seawater desalination vessel according to an embodiment of the present invention includes a freshwater consumption-retention amount management module 120, a route setting module 130, an emergency freshwater supply processing module 140, and a DB It comprises a block 150 and a fresh water supply navigation server 110.

The freshwater consumption-retention amount management module 120 is a DB for real-time freshwater consumption information of each island input from each island and freshwater reserve information input from the seawater desalination vessel 30 under the control of the freshwater supply navigation server 110. It serves to selectively store the freshwater consumption DB 153 for each island and the freshwater reserve DB 154 of the block 150.

Prior to the description of the route setting module 130, the DB block 150 will be first described as follows. The DB block 150 sets an optimal freshwater supply route for passing through a plurality of islands requiring freshwater, and stores all information for calculating the freshwater requirement information of the ship required for the freshwater supply route.

Location information on a plurality of islands to be provided freshwater, freshwater storage capacity of freshwater storage tanks provided in each island, real-time freshwater consumption information of each island, freshwater reserve information of seawater desalination vessels 30, route information passing through each island , It plays a role of storing freshwater requirement information for each route.

The DB block 150 includes, in detail, a book location information DB 151, a freshwater storage capacity DB 152 for each island, a real-time freshwater consumption DB 153 for each island, a freshwater reserve DB 154 for a ship, and a route information DB ( 155).

The book location information DB 151 stores location information on a plurality of books to be provided with fresh water, and GPS information of each book may be stored. The book-specific freshwater storage capacity DB 152 stores freshwater storage capacity information of the freshwater storage tanks provided in each book, and the book-specific real-time freshwater consumption DB 153 stores real-time freshwater consumption information of each book. A water level sensor 23 is provided on one side of the freshwater storage tank of each island, and the freshwater consumption information of the freshwater storage tank detected by the water level sensor 23 is provided through the communication module 21 provided in each island. It may be transmitted to the server 110 and stored in the real-time freshwater consumption DB 153 for each book. The vessel freshwater reserve DB 154 stores freshwater reserve information held by the seawater desalination vessel 30, and between the vessel server 31 and the freshwater supply navigation server 110 provided in the seawater desalination vessel 30 Freshwater reserve information currently held by the seawater desalination vessel 30 may be stored in the vessel freshwater reserve DB 154 through communication.

The route information DB 155 stores basic route information, freshwater supply route information, and freshwater supply route information on freshwater requirements. The basic route means a route that passes through all islands subject to freshwater provision. In this case, a route may be set so that all islands subject to fresh water can be routed through one basic route, or through a plurality of basic routes, all islands subject to freshwater provision may be routed. In the case of setting a plurality of basic routes, for example, if the target of freshwater provision is 10 islands, the first basic route is via islands 1 to 3, and the second basic route is via islands 4 to 6, The 3rd basic route can be set to pass through books 7-10. In the case of setting as one basic route, all books 1 to 10 are passed through one basic route. The basic route can be arbitrarily set and changed by the client 10. Here, the client 10 is connected to the freshwater supply navigation server 110 to generate an event for setting and changing the basic route as described above, as well as storing the location information of the book, storing the freshwater storage capacity for each book, and supplying fresh water. Events necessary for management can be generated.

The freshwater supply route information stored in the route information DB 155 is set by the route setting module 130, which will be described later, based on the basic route information and real-time freshwater consumption information of each book. It means a route excluding islands where fresh water supply is not required.

In addition, the freshwater supply route freshwater requirement information refers to the freshwater requirement information of islands included in the freshwater supply route, and can be calculated based on real-time freshwater consumption information of the islands included in the freshwater supply route.

In the above, the DB block 150 has been described. Following the description of the freshwater consumption-retention amount management module 120, the route setting module 130 serves as follows.

The route setting module 130 sets a freshwater supply route under the control of the freshwater supply navigation server 110, calculates the freshwater requirement of the freshwater supply route, and provides information on the freshwater supply route and the calculated freshwater supply route. It serves to transmit to the ship server 31 of the seawater desalination ship 30 through the freshwater supply navigation server 110.

The freshwater supply route is established as follows. The route setting module 130 checks the books in which fresh water above the reference value is used through the real-time freshwater consumption DB 153 for each book. For example, if more than 70% of freshwater is used compared to the freshwater storage capacity, it can be regarded as a book with freshwater above the standard value. Subsequently, the route setting module 130 extracts books in which fresh water above the reference value is used from the basic route stored in the route information DB 155 and sets a fresh water supply route. In other words, the freshwater supply route can be regarded as a route excluding islands that do not require freshwater supply from the basic route.

In a state in which a freshwater supply route is set, the route setting module 130 calculates by summing the required amount of freshwater required for islands belonging to the freshwater supply route based on the freshwater supply route. The freshwater requirement of each island can be calculated by subtracting the real-time freshwater consumption information of each island from the freshwater storage capacity information of each island.

The freshwater requirement information of the freshwater supply route calculated by the route setting module 130 is transmitted to the vessel server 31 of the seawater desalination vessel 30 through the freshwater supply navigation server 110 as described above. As an embodiment, it is possible to compare the information on the amount of freshwater reserved by the ship and the information on the required amount of freshwater in the freshwater supply route, and transmit the difference to the ship server 31. For example, when the freshwater reserve of the ship is 80L and the freshwater requirement of the freshwater supply route is 100L, the route setting module 130 may transmit information notifying that 20L of freshwater should be additionally produced to the ship server 31. In addition to these embodiments, information on the freshwater required amount of the freshwater supply route is transmitted to the ship server 31, and the ship server 31 prepares the information on the freshwater reserve of the ship and the freshwater required amount information on the freshwater supply route, and whether or not additional freshwater is produced and the freshwater production amount. You can also make yourself judge.

Next, the emergency freshwater supply processing module 140 serves to transmit an emergency freshwater supply message to the ship server 31 in response to the emergency freshwater supply requested from the client 22 of each island. The client 22 of each book can transmit the location information of the book and the emergency freshwater requirement information to the freshwater supply navigation server 110 through the communication module 21 of each book, and the location information of the book and the emergency freshwater requirement information It is transmitted to the ship server 31 in the form of an emergency freshwater supply message by the emergency freshwater supply processing module 140 so that fresh water is urgently supplied to the corresponding island by the seawater desalination ship 30. At this time, when emergency freshwater supply to a specific island is in progress, the freshwater supply amount information for the island is reflected in the real-time freshwater consumption DB for each island of the DB block 150, and the route setting module 130 determines whether or not the emergency freshwater is supplied. Based on the real-time freshwater consumption DB (153) for each island in which is reflected, the freshwater port supply route is set and the ship's freshwater requirement information is calculated.

The freshwater supply navigation server 110 includes real-time freshwater consumption information input from the communication module 21 of each island and ship freshwater reserve information input from the seawater desalination vessel 30 by the freshwater consumption-retention amount management module 120. The role of controlling what is stored in the DB block 150, the freshwater supply route calculated by the route setting module 130 along with controlling the setting of the freshwater supply route by the route setting module 130 and the calculation of the freshwater required amount of the freshwater supply route. The role of delivering information on the freshwater requirements of the route (or the difference between the freshwater reserves of the ship and the freshwater supply route) to the ship server 31 of the seawater desalination vessel 30, urgent freshwater requested from the client 22 of each island It serves to deliver the supply message to the ship server (31). In addition, the freshwater supply navigation server 110 manages all information stored in the DB block 150.

In the above, a freshwater supply system using a seawater desalination vessel according to an embodiment of the present invention has been described. Hereinafter, an operation of a freshwater supply system using a seawater desalination vessel according to an embodiment of the present invention will be described with reference to FIG. 2.

First, in the DB block 150, the location information of all books to be provided with fresh water, information on the freshwater storage capacity of each book, and information on the basic route, which is a route through all the books, are stored through the client 10 (S201).

In this state, the water level sensor 23 provided at one side of the freshwater storage tank of each island detects the water level of the freshwater storage tank, and the water level information of the freshwater storage tank detected by the water level sensor 23 is communicated with each island. It is delivered to the freshwater supply navigation server 110 through the module 21. Under the control of the freshwater supply navigation server 110, the freshwater consumption-retention amount management module 120 stores the input water level information of the freshwater storage tank, that is, the freshwater consumption information of each island. 153) (S202).

In addition, the freshwater reserve information held by the seawater desalination vessel 30 is transmitted to the freshwater supply navigation server 110 by the vessel server 31 of the seawater desalination vessel 30, and the freshwater supply navigation server 110 Under the control, the freshwater consumption-retention amount management module 120 stores the input ship freshwater reserve amount information in the ship freshwater reserve DB 154 of the DB block 150 (S202).

Subsequently, the freshwater supply navigation server 110 identifies books with freshwater above the reference value through the real-time freshwater consumption DB 153 for each island, and supplies freshwater when the number of books with freshwater above the reference value exceeds a preset predetermined value. The route setting process proceeds (S203). In an embodiment, when 5 or more out of 10 islands to be provided with fresh water are islands in which fresh water above a reference value is used, a process of setting a freshwater supply route may be performed.

Specifically, the route setting module 130 checks books in which fresh water above the reference value is used through the real-time freshwater consumption DB 153 for each island, and fresh water above the reference value is used in the basic route stored in the route information DB 155. The island is extracted and a freshwater supply route is set (S204). Subsequently, based on the set freshwater supply route, the freshwater requirement for islands belonging to the freshwater supply route, that is, the freshwater requirement for the freshwater supply route, is summed and calculated (S205). The freshwater requirement of each island can be calculated by subtracting the real-time freshwater consumption information of each island from the freshwater storage capacity information of each island.

In a state where the freshwater supply route is set and the freshwater requirement of the freshwater supply route is calculated, the information on the freshwater supply route and the freshwater requirement of the freshwater supply route can be determined through the freshwater supply navigation server 110 to the ship server of the seawater desalination vessel 30 ( 31) (S206).

The ship server 31 of the seawater desalination vessel 30 satisfies the freshwater requirement of the freshwater supply route by determining whether to produce additional freshwater and the amount of production in comparison with the freshwater requirement of the freshwater supply route and the freshwater reserve of the seawater desalination vessel 30. Make it (S207). Subsequently, finally, when the seawater desalination vessel 30 passes through the islands requiring freshwater while sailing along the freshwater supply route, the freshwater supply method using the seawater desalination vessel according to an embodiment of the present invention is completed (S208).

Meanwhile, the freshwater supply method using a seawater desalination vessel according to an embodiment of the present invention as described above sets an optimal route, that is, a freshwater supply route, based on real-time freshwater consumption information for each island input from each island. It is a method of calculating freshwater requirement information, and based on this, producing fresh water by seawater desalination vessels and supplying fresh water to each island through the corresponding freshwater supply route. have. In response to this case, although not described in the flow chart of Fig. 2, the client 22 of each book may generate an emergency freshwater supply message event including information on the location of the book and emergency freshwater demand, and supply the emergency freshwater. The message is transmitted to the ship server 31 so that fresh water can be urgently supplied to the book.

At this time, when emergency freshwater supply to a specific island is in progress, the freshwater supply amount information for the island is reflected in the real-time freshwater consumption DB for each island of the DB block 150, and the route setting module 130 determines whether or not the emergency freshwater is supplied. Based on the real-time freshwater consumption DB (153) for each island in which is reflected, the freshwater port supply route is set and the ship's freshwater requirement information is calculated.
