Patent document 1: japanese laid-open patent publication No. 2012-22446
Here, in a navigation area such as a sea area or an estuary, a unique standard, regulation, or the like may be set for environmental protection. When a ship is sailing in these sailing areas, the crew must navigate according to established regulations and the like. However, in recent years, regulations set by administrative departments that manage sea areas and harbors have been widely varied, and ship facilities have become diversified, and it has become necessary for crews to perform different operations for each sea area.
Disclosure of Invention
In view of the above, an object of the present invention is to provide a ship control system capable of automatically performing navigation corresponding to a navigation area.
The ship control system according to the present invention includes: a position information acquisition unit that acquires the position of a ship; a navigation region information acquisition unit that acquires navigation region information relating to a region in which a ship is navigating or is predicted to navigate; and an in-ship system control unit that controls the in-ship system based on the voyage area information acquired by the voyage area information acquisition unit, wherein the in-ship system control unit controls at least one of a liquid discharge mode and a liquid intake mode of the ship.
A ship control system is provided with: a position information acquisition unit that acquires the position of the ship; and a navigation area information acquisition unit that acquires navigation area information relating to an area in which the ship is currently or is expected to navigate. Therefore, the navigation area information acquiring unit can grasp which items are restricted or what kind of navigation is required in the navigation area in which navigation is expected or underway. In contrast, the in-ship system control unit controls the in-ship system based on the navigation area information acquired by the navigation area information acquisition unit. Thus, the in-ship system control unit can appropriately control the in-ship system according to the navigation area. Specifically, the in-ship system control unit controls at least one of a liquid discharge mode and a liquid intake mode of the ship. Thus, even when the ship is sailing in a sailing area where environmental restrictions are set for the liquid discharged from the ship, the in-ship system control unit can automatically perform appropriate control so as to comply with environmental regulations. As described above, navigation corresponding to the navigation area can be automatically performed.
The ship control system may further include an alarm output unit that outputs an alarm based on the navigation area information acquired by the navigation area information acquisition unit. In this case, the alarm output unit can notify or warn the crew.
The voyage region information acquisition portion may acquire information that discharge of the domestic water is prohibited as the voyage region information, and the in-ship system control portion may stop the discharge of the domestic water.

The sailing area information acquisition unit may acquire information of a fresh water area into which fresh water flows as sailing area information, and the in-ship system control unit may take in seawater to the ship at a stage before the ship reaches the fresh water area. When the ship is sailing in the fresh water area, the electrolysis cannot be performed, and by taking in seawater that can be subjected to the electrolysis in advance, it is possible to suppress discharge of ballast water in a state in which electrolysis is not performed.
The navigation area information acquisition part may acquire information of a washing tower drain standard as the navigation area information, and the in-ship system control part may stop the drain of the washing tower drain. Thus, in a navigation area where the washing tower drainage is restricted, navigation complying with the restriction can be automatically performed.
The navigation area information acquisition unit may further acquire restriction information on noise as the navigation area information, and the in-ship system control unit may suppress noise from the ship when the restriction information on noise is acquired.

Detailed Description
Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description, the same or corresponding portions are denoted by the same reference numerals, and redundant description thereof is omitted.
Fig. 1 is a schematic cross-sectional view showing an example of a ship to which a ship control system 100 according to an embodiment of the present invention is applied. The ship 1 is, for example, a ship for transporting a petroleum-based liquid cargo such as crude oil or liquefied gas, and is, for example, a tanker. The vessel is not limited to a tanker, and may be, for example, a bulk carrier or various other vessels.
As shown in fig. 1, the ship 1 includes a hull 11 and a propeller 12. The hull 11 has a bow 2, a stern 3, a turbine room 4, a pump room 5, and a cargo hold 6. A deck 19 is provided in the upper part of the hull 11 (or in the ship). The prow 2 is located on the front side of the hull 11. The stern portion 3 is located on the rear side of the hull 11. The propeller 12 is used to propel the hull 11, and the propeller 12 uses, for example, a stern shaft. The propeller 12 is provided below the waterline (the water surface of the sea W) of the stern portion 3. A rudder 15 for adjusting the propulsion direction is provided below the waterline in the stern portion 3.
The turbine room 4 is provided at a position adjacent to the stern portion 3 on the bow side. The turbine room 4 is a section for arranging a device 16 for imparting driving force to the propeller 12. The pump room 5 is provided at a position adjacent to the turbine room 4 on the bow side. The pump chamber 5 is a section in which a pump 17 and the like are arranged. The cargo hold 6 is provided between the bow 2 and the pump room 5. The cargo hold 6 is a section for containing petroleum-based cargo. By adopting the double hull structure of the outer hull 20 and the inner bottom hull 21, the cargo tank 6 is partitioned into the cargo tank 26 and the ballast tank 27. The cargo tank 26 is loaded with petroleum-based cargo transported by the ship 1. The ballast tank 27 contains ballast water in an amount corresponding to the size of the ship or the like.
A living area 22 where crews live is provided above the turbine room 4 on the deck 19. A scrubber 23 for treating the exhaust gas generated by the facility 16 is provided near the residential area 22.
Next, a ship control system 100 according to an embodiment of the present invention will be described with reference to fig. 2. Fig. 2 is a diagram showing a block configuration of the ship control system 100 according to the embodiment of the present invention. As shown in fig. 2, the ship control system 100 includes a control unit 30, an alarm output unit 35, and an in-ship system 40.
The alarm output section 35 is a device for outputting an alarm. The alarm output unit 35 may output visual information through a monitor, a warning lamp, or the like, for example. The alarm output unit 35 may output auditory information through a speaker, an alarm, or the like. The alarm output unit 35 outputs an alarm based on the content of the alarm information acquired from the control unit 30.
The in-ship system 40 is various systems provided in the ship 1. The in-ship system 40 controls the system to be controlled according to the control signal from the control unit 30. The in-ship system 40 includes a domestic water control system 41, a ballast water control system 42, a scrubber control system 43, an exhaust gas control system 44, and a noise control system 46. The control of the in-ship system 40 will be described later.
The control unit 30 is a device that performs various calculations for controlling the ship 1. The control unit 30 includes a processor, a memory, a storage, and a communication interface, and is configured by a general computer. The processor is an arithmetic Unit such as a CPU (Central Processing Unit). The Memory is a storage medium such as a ROM (Read only Memory) or a RAM (Random Access Memory). The memory is a storage medium such as an HDD (Hard Disk Drive). The communication interface is a communication device that implements data communication. The processor centrally controls the memory, storage, and communication interface, thereby realizing the functions of the control section 30 described later. In the control section 30, for example, various functions are realized by loading a program stored in the ROM into the RAM and executing the program loaded in the RAM by the CPU. The control unit 30 may be constituted by a plurality of computers. The control unit 30 includes a position information acquisition unit 31, a navigation area information acquisition unit 32, an in-ship system control unit 33, and a database 34.
The position information acquiring unit 31 acquires position information indicating the position of the ship 1. The position information acquiring unit 31 acquires position information from a measurement system such as a GPS. The position information acquiring unit 31 can acquire a planned navigation position (and a planned time thereof) at which the ship 1 is expected to travel, based on the current navigation information and route plan information.
The navigation area information acquisition unit 32 acquires navigation area information relating to an area in which the ship 1 is currently traveling or is expected to travel. The navigation area is an area where the ship 1 navigates, and indicates an ocean area, an estuary, and the like when navigating on the sea. The navigation area information includes, for example, information such as restrictions, standards, and prohibited items set in the navigation area. The information about the sailing area may include information about the characteristics of the sailing area, for example, information about whether the sea water is fresh water. The navigation area information acquiring unit 32 acquires navigation area information by comparing the position information acquired by the position information acquiring unit 31 with the information stored in the database 34. In this manner, the database 34 stores the travel area information in each travel area.
The navigation area information acquisition unit 32 extracts alarm information from the navigation area information, and controls the alarm output unit 35 to output an alarm at a necessary timing. Thus, the alarm output unit 35 outputs an alarm based on the navigation area information acquired by the navigation area information acquisition unit 32. For example, when information such as a standard or prohibited item is acquired as the navigation area information, the navigation area information acquiring unit 32 extracts notification, warning, and the like of items that the crew needs to attend as the alarm information.
Next, the navigation area information will be described with reference to fig. 3. Fig. 3 is a sea chart showing a state of the sea where the ship 1 is sailing. As shown in fig. 3, a designated sea area a, a designated sea area B, and a designated sea area C exist according to the location. Since individual regulations, standards, and the like are established in these sea areas, it is necessary to set alarm information corresponding to the regulations, standards, and the like. For example, the alarm information N, A, D is set in the designated sea area a, the alarm information N, B is set in the designated sea area B, the alarm information N, C, A is set in the designated sea area C, and the alarm information N is set in the other sea areas. Here, the alarm information N may be alarm information indispensable in the entire sea area. For example, when the ship 1 is sailing in the designated sea area B, the sailing region information acquisition unit 32 acquires sailing region information in the designated sea area B from the database 34, and extracts the warning information N, B therefrom.
The in-ship system control unit 33 controls the in-ship system 40 based on the travel area information acquired by the travel area information acquisition unit 32. That is, the in-ship system control unit 33 controls the in-ship system 40 so that the ship can automatically sail in an appropriate state in the sailing area, based on the sailing area information in which the ship 1 is sailing and the sailing area information expected to sail. The in-ship system control unit 33 may perform control corresponding to the alarm information in conjunction with the alarm output unit 35 when the alarm is generated. Further, based on the alarm information, a warning alarm may be output that warns the ship 1 of the entry into the designated sea area in advance by the alarm output unit 35.
The in-ship system control unit 33 controls an event of discharge or supply from the ship 1 according to the voyage area. For example, the in-ship system control unit 33 can control the liquid discharge method and the liquid intake method of the ship.
Specifically, the discharge pattern of the domestic water discharged from the ship 1 can be controlled. Depending on the sea area (e.g., black sea), there are also sea areas where discharge of domestic wastewater is prohibited. At this time, domestic sewage that the crew has used cannot be discharged from the ship 1. When the ship 1 enters such a sea area, the voyage area information acquisition unit 32 acquires information that discharge of domestic water is prohibited as the voyage area information. In contrast, the alarm output unit 35 sounds an alarm indicating that the discharge of the domestic water is prohibited. And, the in-ship system control part 33 controls the domestic water control system 41 to stop the discharge of the domestic water. The domestic water control system 41 includes, for example, a domestic water supply system and a domestic water drainage system. The domestic water control system 41 controls a valve or the like so as not to flow used domestic water to a drain port that discharges domestic water toward the sea. The domestic water control system 41 stores the used domestic water in a tank or the like.
Further, the manner of taking in the ballast water taken into the ship 1 may be controlled. The seawater taken into the ballast tank 27 has a salt concentration of at least a certain level, and needs to be electrolyzed. Therefore, if there is a sea area into which fresh water flows on the planned route, ballast water cannot be taken into the sea area. When the ship 1 approaches such a sea area, the alarm output unit 35 issues a warning in advance before entering the sea area. The navigation area information acquiring unit 32 acquires information of a fresh water area into which fresh water has flowed as navigation area information. The in-ship system control unit 33 controls the ballast water control system 42 to take in seawater to the ship 1 at a stage before the ship reaches the fresh water area. This allows the ballast water control system 42 to take in seawater having a high salt concentration. Ballast water control system 42 has pump 17 within pump chamber 5. The ballast control system 42 controls the pump 17 at the early stage of entering the sea area of fresh water to take in seawater having a high salt concentration from the seawater and supply it to the ballast tank 27.
Further, the discharge mode of the scrubber tower drain discharged from the vessel 1 may also be controlled. Depending on the sea area, a standard higher than the standard specified in IMO may be set for the drainage standard of the scrubber drainage. At this time, when the ship 1 enters the sea area, the navigation area information acquiring unit 32 acquires information of the washing tower drainage standard as the navigation area information. Then, the alarm output portion 35 issues a warning that the drain of the scrubber tower drain cannot be performed. And, the in-ship system control part 33 controls the washing tower control system 43 to stop the discharge of the washing tower drain water. The scrubber control system 43 includes a supply system and a drain system for water used for the exhaust gas treatment in the scrubber 23. The scrubber control system 43 controls valves and the like so as not to flow the scrubber drain to a drain that drains the scrubber drain toward the sea. The scrubber control system 43 stores the treated scrubber drain water in a tank or the like.
The travel area information acquiring unit 32 may acquire restriction information of the exhaust gas as the travel area information. At this time, the in-ship system control unit 33 controls the exhaust gas treatment method. The NOx reduction treatment of the exhaust gas of the scrubber 23 as the emission is controlled. That is, according to the secondary standards of NOx by IMO, NOx Emission is restricted in the entire sea Area, but when ECA (Emission Control Area): 200 nautical miles on the coast of north america canada and the sea Area of the caribbean sea) is passed, the more strict tertiary standard is applied. Therefore, in this sea area, after the alarm is issued, the in-ship system control unit 33 controls the exhaust gas control system 44. Specifically, the exhaust gas control system 44 automatically activates an SCR (Selective Catalytic Reduction) to respond. This processing is performed when it is detected in advance (two hours or so before) that the sea approaches the sea area. The exhaust gas control system 44 heats some of the facilities (such as a reactor) for about two hours in order to promote chemical reaction. When entering the sea, the exhaust gas control system 44 automatically operates valves to deliver exhaust gas to the SCR to react NOx with the urea water for treatment.
The navigation area information acquiring unit 32 may acquire the limit information of the noise as the navigation area information. At this time, the in-ship system control unit 33 controls the operation mode. That is, the operation manner is controlled to reduce the noise emitted from the ship 1. In recent years, it is considered that underwater noise generated from the ship 1 may affect marine life. When a limit for noise is set, it is necessary to reduce underwater noise in a restricted estuary or sea area. Therefore, if there is a possibility of entering the navigation area where the noise is restricted (when the restriction information of the noise is acquired), the in-ship system control unit 33 controls the noise control system 46 to reduce the noise from the ship. The noise control system 46 suppresses noise by attenuating or stopping the operation of a mechanism in the ship 1 that causes noise. For example, noise control system 46 reduces the rotational speed of the propeller of thruster 12. Alternatively, the output of the propeller 12 may be reduced.
Next, the control content of the ship control system 100 will be described with reference to fig. 4. As shown in fig. 4, the navigation area information acquiring unit 32 first confirms the current position of the ship 1 and the current route based on the position information acquired by the position information acquiring unit 31 (step S10). Then, the navigation area information acquiring unit 32 acquires navigation area information by collating the content confirmed at step S10 with the information stored in the database 34 (step S20). Then, the navigation area information acquiring unit 32 extracts the alarm information from the navigation area information and outputs an alarm through the alarm output unit 35 (step S30). Then, the in-ship system control unit 33 controls the in-ship system 40 in an appropriate manner based on the navigation area information acquired in step S20 (step S40). This completes the processing shown in fig. 4.
Next, the operational effects of the ship control system 100 according to the present embodiment will be described.
The ship control system 100 includes a position information acquisition unit 31 that acquires the position of the ship 1, and a navigation area information acquisition unit 32 that acquires navigation area information regarding an area in which the ship 1 is currently traveling or is expected to travel. Therefore, the navigation area information acquiring unit 32 can grasp which items are restricted or which navigation is required during navigation or in the navigation area where navigation is expected. On the other hand, the in-ship system control unit 33 controls the in-ship system 40 based on the travel area information acquired by the travel area information acquisition unit 32. Thereby, the in-ship system control unit 33 can appropriately control the in-ship system 40 according to the navigation area. Specifically, the in-ship system control unit 33 controls at least one of a liquid discharge method and a liquid intake method of the ship. Thus, even when the ship 1 is sailing in a sailing area where environmental regulations or the like are prescribed for the liquid discharged from the ship, the in-ship system control unit 33 can automatically perform appropriate control so as to comply with the environmental regulations. As described above, navigation corresponding to the navigation area can be automatically performed.
The ship control system 100 may further include an alarm output unit 35 that outputs an alarm based on the navigation area information acquired by the navigation area information acquisition unit 32. At this time, the alarm output unit 35 can notify or warn the crew.
The voyage region information acquisition portion 32 may acquire information that discharge of domestic water is prohibited as the voyage region information, and the in-ship system control portion 33 may stop the discharge of domestic water. Thus, in a navigation area where there is a restriction on the discharge of domestic water, navigation complying with the restriction can be automatically performed.
The sailing area information acquisition unit 32 can acquire information of a fresh water area into which fresh water has flowed as sailing area information, and the in-ship system control unit 33 can take in seawater to the ship 1 before the fresh water area is reached. When the ship 1 travels in the fresh water area, the electrolytic treatment cannot be performed, and by taking in seawater that can be subjected to the electrolytic treatment in advance, it is possible to suppress discharge of ballast water in a state where the electrolytic treatment is not performed.
The sailing region information acquisition part 32 may acquire information of the washing tower drain standard as sailing region information, and the in-ship system control part 33 may stop the draining of the washing tower drain. Thus, in a navigation area where the washing tower drainage is restricted, navigation complying with the restriction can be automatically performed.
The ship control system 100 according to the present embodiment includes: a position information acquisition unit 31 that acquires the position of the ship 1; a navigation area information acquisition unit 32 that acquires navigation area information relating to an area in which the ship 1 is currently or is expected to navigate; and an in-ship system control unit 33 for controlling the in-ship system 40 based on the navigation area information acquired by the navigation area information acquisition unit 32, wherein the navigation area information acquisition unit 32 acquires restriction information of exhaust gas as the navigation area information, and the in-ship system control unit 33 controls the treatment method of the exhaust gas.
According to the ship control system 100, in a navigation area where a restriction is set for exhaust gas, navigation complying with the restriction can be automatically performed.
The ship control system 100 according to the present embodiment includes: a position information acquisition unit 31 that acquires the position of the ship 1; a navigation area information acquisition unit 32 that acquires navigation area information relating to an area in which the ship 1 is currently or is expected to navigate; and an in-ship system control unit (33) for controlling the in-ship system (40) on the basis of the navigation area information acquired by the navigation area information acquisition unit (32), wherein the navigation area information acquisition unit (32) acquires noise restriction information as navigation area information, and the in-ship system control unit (33) controls the operation mode.
According to the ship control system 100, in a navigation area where a restriction is placed on noise, navigation complying with the restriction can be automatically performed.
The present invention is not limited to the above-described embodiments.
In the above embodiment, the navigation area information is exemplified by the restriction, the standard, and the like, but the navigation area information is not limited to the above examples. When the limit or the standard is changed, the in-ship system control unit may perform control corresponding to the limit or the standard.
For example, although the above embodiment has been described with a large ship as an example, the ship control system may be employed in a small ship. In addition, if a small-sized ship is used, the ship can navigate not only in the sea but also in rivers and the like.
When a registered Wi-Fi is detected in a set bay or the like, a route in the ship can be automatically switched while an alarm is output.
