A conventional ship is described in Patent Document 1. This ship is loaded with cargo and navigates long distances along a specified route, and various types of work are carried out using various equipment on board.

JP 2008-132974 A

On a ship, while sailing or performing operations using equipment, the ship's condition is monitored, and if an abnormality is detected, an alarm is output on board. Some alarms may be more important than others. Such alarms must be dealt with reliably after the reason for their occurrence and the appropriate response have been thoroughly confirmed. Therefore, there has been a demand for improving the reliability of responses to alarms.

The present invention aims to provide a ship monitoring system and a ship monitoring device that can improve the reliability of responding to alarms.

The ship monitoring system of the present invention is a ship monitoring system that monitors the status of a ship, and includes a ship status acquisition unit that acquires ship status information related to the status of the ship, an alarm unit that outputs an alarm based on the ship status information, an alarm cancellation unit that cancels the alarm based on whether or not approval has been given for the cancellation of the alarm, a first approval unit that is provided on the ship and approves the cancellation of the alarm, and a second approval unit that approves the cancellation of the alarm, and the alarm cancellation unit cancels the alarm when approval has been given by the first approval unit and the second approval unit.

The ship monitoring system includes an alarm unit that outputs an alarm based on ship status information, and an alarm cancellation unit that cancels the alarm based on whether or not approval has been given for the cancellation of the alarm. Therefore, when an alarm is output, the alarm cancellation unit cancels the alarm when necessary measures for canceling the alarm are taken and approval has been given. Here, if the alarm cancellation unit is provided on the ship and the alarm is cancelled only with approval from the first approval unit that approves the cancellation of the alarm, crew members on board may be able to easily cancel the alarm on their own. If the alarm can be easily cancelled, depending on the content of the alarm, the confirmation and measures for cancellation may not be reliable. In contrast, in the present invention, the alarm cancellation unit cancels the alarm when approval has been given from the first approval unit and the second approval unit. Therefore, the alarm cancellation unit can set not only approval from the first approval unit but also approval from the second approval unit as a condition for canceling the alarm. In this case, even if the crew member gives approval from the first approval unit, the alarm will not be cancelled unless approval has been given from the second approval unit. In other words, crew members will no longer be able to easily cancel an alarm on their own, so they will need to thoroughly check the situation before taking action and giving approval to cancel the alarm. This will improve the reliability of responses to alarms.

The first approval unit may obtain the cause of the alarm and the countermeasures, and the second approval unit may provide the cause and countermeasures to the approver who performs the second approval. In this case, the approver of the second approval unit can confirm that the crew correctly understands the cause of the alarm and takes the correct countermeasures. In addition, the crew who performs the approval in the first approval unit will have the contents checked by the approver of the second approval unit, so they can thoroughly check before taking the countermeasures and approving to cancel the alarm.

The second approval section may be provided outside the ship. In this case, an approver outside the ship will perform approval at the second approval section. In this case, the process for deactivating the alarm is not completed solely within the ship, but an approver other than the ship's crew can also check for deactivating the alarm. This can improve the reliability of the response to the alarm.

The second approval department may be located on land. In this case, the approvers of the second approval department are not limited to those who are at sea, and it becomes possible to select a more appropriate approver from among those who are on land.

The second approval unit may provide the ship status information to the approver. In this case, the approver of the second approval unit can also refer to the ship status information to confirm that the problem has been reliably resolved before approving the problem.

The ship monitoring device of the present invention is a ship monitoring device that monitors the state of a ship, and includes a ship state acquisition unit that acquires ship state information regarding the state of the ship, an alarm unit that outputs an alarm based on the ship state information, an alarm cancellation unit that cancels the alarm based on whether or not approval has been given for the cancellation of the alarm, a first approval unit that approves the cancellation of the alarm, and a receiving unit that receives approval information for the cancellation of the alarm from a second approval unit different from the first approval unit, and the alarm cancellation unit cancels the alarm when approval has been given by the first approval unit and the second approval unit.

This ship monitoring device can achieve the same effects and benefits as the ship monitoring system described above.

The present invention provides a ship monitoring system and a ship monitoring device that can improve the reliability of responding to alarms.

1 is a block diagram showing a configuration of a vessel monitoring system according to an embodiment of the present invention. FIG. 2 is a schematic diagram showing communication in a ship monitoring system. 4 is a flowchart showing the contents of a control process of the vessel monitoring device. FIG. 2 is a schematic diagram showing a state in which a ship deviates from its course.

A preferred embodiment of the present invention will now be described in detail with reference to the accompanying drawings. In the following description, the same or equivalent parts will be designated by the same reference numerals, and duplicated descriptions will be omitted.

Figure 1 is a block diagram showing the configuration of a ship monitoring system 100 according to this embodiment. Figure 2 is a schematic diagram showing the state of communication in the ship monitoring system 100. The ship monitoring system 100 shown in Figure 1 includes a ship monitoring device 10 mounted on a ship 1 and a terminal 20. The ship monitoring device 10 and the terminal 20 can transmit and receive information via a network NW. In this embodiment, as shown in Figure 2, the network NW is composed of satellite communication using an artificial satellite S and communication using a cloud server CD. The terminal 20 is also installed outside the ship 1. Here, the terminal 20 is installed in an office on land, etc. This allows the crew of the ship 1 to share information with an administrator in an office on land via the network NW and the terminal 20. Note that although only one ship 1 is shown in Figures 1 and 2, the ship monitoring system 100 may include ship monitoring devices 10 for multiple ships 1. In other words, an administrator in an office on land may manage multiple ships 1 using the terminal 20.

The ship 1 is equipped with various detection units 2 for detecting various conditions of the ship 1. The detection units 2 transmit ship condition information relating to the detected conditions of the ship 1 to the ship monitoring device 10.

The ship monitoring device 10 monitors the ship 1 for abnormalities and communicates with the terminal 20 via the network NW. The ship monitoring device 10 is equipped with a processor, memory, storage, a communication interface, and a user interface, and is configured as a general computer. The processor is a computing device 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 storage is a storage medium such as a HDD (Hard Disk Drive). The communication interface is a communication device that realizes data communication. The user interface is an output device such as an LCD or a speaker, and an input device such as a keyboard, a touch panel, or a microphone. The processor controls the memory, storage, communication interface, and user interface, and realizes the functions of the ship monitoring device 10 described below. In the ship monitoring device 10, for example, a program stored in the ROM is loaded into the RAM, and the program loaded into the RAM is executed by the CPU to realize various functions. The ship monitoring device 10 may be composed of multiple computers.

As shown in FIG. 1, the ship monitoring device 10 includes a ship status acquisition unit 11, an alarm unit 12, an alarm cancellation unit 13, a first approval unit 14, and a transmission/reception unit 16.

The ship state acquisition unit 11 acquires ship state information relating to the state of the ship 1. The ship state acquisition unit 11 acquires the detection results of the various detection units 2 and performs calculations based on those detection results to acquire ship state information for determining whether there are any abnormalities in the ship 1.

The alarm unit 12 outputs an alarm based on the ship status information. The alarm unit 12 determines whether any abnormality has occurred in the ship 1 by referring to the ship status information. Then, if the alarm unit 12 determines that an abnormality has occurred in the ship 1, it outputs an alarm. Note that the method of outputting an alarm by the alarm unit 12 is not particularly limited, and for example, a warning message or image may be displayed on a monitor, or a warning may be issued by sound such as a buzzer. At this time, the alarm unit 12 may output the details of the abnormality and the items that should be checked to resolve the abnormality.

The alarm cancellation unit 13 cancels the alarm based on whether or not approval has been given for the alarm cancellation. The alarm cancellation unit 13 cancels the alarm when approval has been given by the first approval unit 14 on board the ship and by the second approval unit 21 of the terminal 20 on land, which will be described later.

Here, the alarm cancellation unit 13 may classify alarm contents into alarm contents that can be cancelled only by the first approval unit 14 on board and alarm contents that require a second approval on land in addition to the first approval on board. When the alarm contents require a second approval on land, the alarm cancellation unit 13 may transmit an alarm to the terminal 20 on land. The alarm cancellation unit 13 transmits an alarm to the terminal 20 (see FIG. 2) in the on-shore office via the transmission/reception unit 16. At this time, the alarm cancellation unit 13 transmits information (information entered by the crew) such as the cause of the alarm and the measures taken on board in addition to the alarm contents. Furthermore, the alarm cancellation unit 13 may transmit ship status information acquired by the ship status acquisition unit 11 to the terminal 20 so that the on-shore manager can check whether the problem has actually been resolved.

An example of an alarm content that requires a first approval on board and a second approval on land (hereinafter, sometimes referred to as two-stage approval) will be described. For example, the alarm cancellation unit 13 may classify an alarm of a route deviation of the ship 1 as an alarm content that requires two-stage approval. Specifically, as shown in FIG. 4, when the actual route P1 deviates from the expected route P2 by more than a predetermined threshold, the alarm unit 12 determines that a route deviation has occurred and outputs an alarm. In this case, the detection unit 2 detects the actual route by calculating it.

The alarm reset unit 13 may classify an alarm of an equipment abnormality into an alarm content that requires two-stage approval. For example, an alarm of an overload of a generator engine (G/E) may be included. The detection unit 2 detects the load of the generator engine. The number of generator engines in use is changed depending on the operating conditions. For example, a state in which one of three installed engines is in use may be changed to a state in which two engines are in use. Therefore, one generator engine may be overloaded due to a failure or a switching malfunction. When an alarm regarding such a failure or malfunction is issued, the switching control of the generator engine is basically performed automatically, but a manual emergency stop may be required. Therefore, the alarm reset unit 13 may classify such an alarm into an alarm content that requires two-stage approval. The alarm reset unit 13 may also transmit and share information about the equipment to the terminal 20 on land. This allows the land manager to perform the second approval after confirming whether the problem has actually been solved based on not only the information input by the crew but also the shared information.

The alarm cancellation unit 13 may classify the gas detection alarm into alarm contents requiring two-stage approval. In this case, the detection unit 2 detects leaks based on the gas concentration, etc. Strict confirmation is required for gas detection to ensure safety. In addition, since various new fuels will appear in the future, even if the alarm is dealt with without being ignored, there is a possibility that the gas leakage of each fuel will be dealt with incorrectly. Therefore, in order to improve safety and to deal with new fuels, the alarm cancellation unit 13 may classify the gas detection alarm into alarm contents requiring two-stage approval. The alarm cancellation unit 13 may transmit the detection information of the gas detection sensor to the land terminal 20 and share it. In this way, the land manager can perform the second approval after confirming whether the problem has actually been solved based on not only the input information by the crew but also the shared information.

The first approval unit 14 approves the deactivation of the alarm. The first approval unit 14 approves the deactivation of the alarm on the inside of the ship by acquiring an input operation for approval from the crew member. The first approval unit 14 acquires input from the crew member about the cause of the alarm and the details of the response.

The transmitting/receiving unit 16 transmits and receives various information. The transmitting/receiving unit 16 transmits and receives information to and from a terminal 20 on land via the network NW. The transmitting/receiving unit 16 transmits information on the alarm content, the cause of the alarm, and the countermeasure content inputted by the first approval unit 14. The transmitting/receiving unit 16 also functions as a receiving unit that receives approval information for the cancellation of the alarm from a second approval unit 21 that is provided at a different location (on land) from the first approval unit 14.

The terminal 20, like the ship monitoring device 10 described above, has a processor, memory, storage, a communication interface, and a user interface. The processor controls the memory, storage, communication interface, and user interface, and realizes the functions of the terminal 20 described below. The terminal 20 may be composed of multiple computers. The terminal 20 has a second approval unit 21 and a transmission/reception unit 22.

The second approval unit 21 approves the deactivation of the alarm. The second approval unit 21 approves the deactivation of the alarm on the land side by acquiring an input operation for approval from the manager of the onshore office. The second approval unit 21 provides the manager (approver) with the alarm contents, as well as the cause of the alarm and the countermeasures entered on the ship 1 side. When the alarm deactivation unit 13 transmits ship status information to the terminal 20, the second approval unit 21 provides the ship status information to the manager. The method of providing each piece of information when the second approval unit 21 provides each piece of information to the manager is not particularly limited. For example, the second approval unit 21 may summarize the identification information of the ship 1, the alarm contents, the cause of the alarm, the countermeasures, the ship status information, etc. in a table format and display the table on the monitor. The second approval unit 21 may also display an approval button on the monitor so that the manager can easily approve by clicking it.

The transmission/reception unit 22 transmits and receives various information. The transmission/reception unit 22 transmits and receives information to and from the ship 1 via the network NW. The transmission/reception unit 22 transmits approval information from the second approval unit 21. The transmission/reception unit 22 also receives various information such as those described above to be provided by the manager for approval.

Next, an example of the contents of the control process of the ship monitoring system 100 will be described with reference to FIG. 3. The control process shown in FIG. 3 is executed by the ship monitoring device 10.

As shown in FIG. 3, first, the ship state acquisition unit 11 acquires ship state information from each detection unit 2 (step S10). The alarm unit 12 determines whether or not an abnormality has occurred within the ship 1 based on the ship state information acquired in step S10 (step S20). If it is determined in step S20 that no abnormality has occurred, the control process shown in FIG. 3 ends. On the other hand, if it is determined in step S20 that an abnormality has occurred, the alarm unit 12 outputs an alarm (step S30).

Next, the alarm cancellation unit 13 waits for the first approval to be given on board the ship, and acquires the approval information when the first approval is given (step S40). When approval is given by a crew member in the first approval unit 14, the alarm cancellation unit 13 acquires information that approval has been given, as well as information on the cause of the incident and the details of the response entered by the crew member.

The alarm cancellation unit 13 requests a second approval from the second approval unit 21 by transmitting the alarm content, cause of occurrence, countermeasures, and ship status information to the terminal 20 (step S50). Next, the alarm cancellation unit 13 waits for the second approval to be made at the on-shore terminal 20, and acquires the approval information when the second approval is made (step S60). When approval is made by the on-shore manager at the second approval unit 21, the alarm cancellation unit 13 acquires information that approval has been made.

When the process of step S60 is completed, the alarm cancellation unit 13 determines that approval has been given by the first approval unit 14 and the second approval unit 21, and cancels the alarm (step S70). This ends the control process shown in FIG. 3, and the process is repeated from S10.

Next, we will explain the operation and effects of the ship monitoring system 100 and the ship monitoring device 10 according to this embodiment.

The ship monitoring system 100 includes an alarm unit 12 that outputs an alarm based on ship status information, and an alarm cancellation unit 13 that cancels the alarm based on whether or not approval has been given for the cancellation of the alarm. Therefore, when an alarm is output, the alarm cancellation unit 13 cancels the alarm when necessary measures for canceling the alarm are taken and approval has been given. Here, if the alarm cancellation unit 13 is provided on the ship 1 and the alarm is cancelled only by approval from the first approval unit that approves the cancellation of the alarm, crew members on board may be able to easily cancel the alarm on their own. If the alarm can be easily cancelled, depending on the content of the alarm, the confirmation and measures for cancellation may not be reliable. In contrast, in this embodiment, the alarm cancellation unit 13 cancels the alarm when approval has been given from the first approval unit 14 and the second approval unit 21. Therefore, the alarm cancellation unit 13 can set not only approval from the first approval unit 14 but also approval from the second approval unit 21 as conditions for canceling the alarm. In this case, even if the crew member gives approval in the first approval unit 14, the alarm will not be deactivated unless approval is also given in the second approval unit 21. In other words, the crew member will not be able to deactivate the alarm easily on their own, so they will need to thoroughly check before taking action and approving the alarm deactivation. As a result, the reliability of responses to alarms can be improved.

The first approval unit 14 may obtain the cause of the alarm and the countermeasures, and the second approval unit 21 may provide the cause of the alarm and the countermeasures to the approver. In this case, the approver of the second approval unit 21 can confirm that the crew correctly understands the cause of the alarm and takes the correct countermeasures. In addition, the crew who approves through the first approval unit 14 will have the contents checked by the approver of the second approval unit 21, so they can thoroughly check before taking the countermeasures and approving to cancel the alarm.

The second approval unit 21 may be provided outside the ship 1. In this case, an approver outside the ship 1 will perform approval in the second approval unit 21. In this case, the process for deactivating the alarm is not completed solely within the ship 1, but an approver other than the crew of the ship 1 can also check for deactivating the alarm. This can improve the reliability of the response to the alarm.

The second approval unit 21 may be provided on land. In this case, the approvers of the second approval unit 21 are not limited to those at sea, and it becomes possible to select a more appropriate approver from among those present on land. For example, if there is a person in the office who is knowledgeable about abnormalities on the ship 1, that person can perform the approval in the second approval unit 21.

The second approval unit 21 may provide the approving person with ship status information. In this case, the approving person of the second approval unit 21 can also refer to the ship status information to confirm that the problem has been reliably resolved before approving the problem.

The ship monitoring device 10 according to this embodiment is a ship monitoring device 10 that monitors the state of the ship 1, and includes a ship state acquisition unit 11 that acquires ship state information related to the state of the ship 1, an alarm unit 12 that outputs an alarm based on the ship state information, an alarm cancellation unit 13 that cancels the alarm based on whether or not approval has been given for the cancellation of the alarm, a first approval unit 14 that approves the cancellation of the alarm, and a transmission/reception unit 16 (receiving unit) that receives approval information for the cancellation of the alarm from a second approval unit different from the first approval unit 14, and the alarm cancellation unit 13 cancels the alarm when approval has been given by the first approval unit 14 and the second approval unit 21.

The present invention is not limited to the above-described embodiments.

For example, the configuration of the ship monitoring system 100 and the ship monitoring device 10 shown in FIG. 1 is merely an example, and may be modified as appropriate without departing from the spirit of the present invention.

In the example shown in FIG. 2, the terminal 20 having the second approval unit 21 is provided on land, but this is not limited thereto. For example, the terminal 20 may be provided on another ship, an offshore facility, or the like. For example, if there is a ship on which a manager is aboard and a ship on which a worker is aboard, the second approval unit 21 may be provided on the ship on which the manager is aboard, and the manager may become the approver. In addition, the second approval unit 21 is provided outside the ship 1, but this is not limited thereto. That is, the second approval unit 21 may be provided on the same ship 1. For example, the person in charge (such as the captain) of the ship 1 may give approval using the second approval unit 21. In this case, the second approval unit 21 may be provided on a PC in the person in charge's room, or the second approval unit 21 may be provided on a mobile terminal carried by the person in charge. Alternatively, the first approval unit 14 and the second approval unit 21 may be provided on the same terminal. In this case, it may be possible to distinguish between a crew member who can give approval in the first approval unit 14 and a person in charge who can give approval in the second approval unit 21. For example, when giving approval in the second approval unit 21, a process for authenticating the approver may be performed.
