[0034] Hereinafter, embodiments of the present invention will be described in more detail with reference to the attached drawings. However, the present invention is not limited to the embodiments disclosed below but may be implemented in various different forms, and these embodiments are provided merely to ensure that the disclosure of the present invention is complete and to fully inform those skilled in the art of the scope of the invention. To describe the invention in detail, the drawings may be exaggerated, and like reference numerals in the drawings refer to like elements.

[0036] FIG. 1 is a diagram showing the configuration of a ship propulsion system monitoring device according to an embodiment of the present invention, FIG. 2 is a diagram showing a screen in which a first display window of a display unit according to an embodiment of the present invention displays a configuration diagram of equipment equipped in a ship propulsion system, FIG. 3 is a diagram showing a screen in which a second display window of a display unit according to an embodiment of the present invention displays maintenance information of equipment with defects, and FIG. 4 is a diagram showing a screen in which a display unit according to an embodiment of the present invention displays the health index of equipment equipped in a ship propulsion system. Below, a ship propulsion system monitoring device according to an embodiment of the present invention will be described.

[0037] A ship propulsion system monitoring device is a monitoring device provided in an integrated engine control system to diagnose whether an abnormality has occurred in the equipment provided in the ship propulsion system. Referring to FIG. 1, the ship propulsion system monitoring device (100) includes a display unit (130), a diagnosis unit (110), and a processing unit (120).

[0038] At this time, the ship propulsion system (50) may include a combined diesel-electric or gas turbine propulsion system (CODLOG). The equipment provided in the combined diesel-electric or gas turbine propulsion system may include a gas turbine, a reduction gear, a plurality of generators, a plurality of electric motors, and a plurality of propellers. However, the types of propulsion systems included in the ship propulsion system (50) and the types of equipment provided by the propulsion systems are not limited to these and may vary.

[0039] The display section (130) can visually display a configuration diagram of the equipment equipped in the ship propulsion system (50). For example, the display section (130) may be a display, and the display section (130) may include a first display window (131) and a second display window (132) that appear on the display.

[0040] The first display window (131) can display a configuration diagram showing the structure in which the equipment equipped in the ship propulsion system (50) is connected to the respective locations of the equipment. For example, if the ship propulsion system (50) includes a diesel-electric-gas turbine combined propulsion system, the first display window (131) can visually display a configuration diagram of the equipment equipped in the diesel-electric-gas turbine combined propulsion system, such as a gas turbine, reduction gear, multiple generators, multiple electric motors, and multiple propellers, as shown in FIG. 2. The first display window (131) can display the equipment included in the configuration diagram in the same first color. Thus, the operator of the ship can easily visually check the configuration diagram of the equipment.

[0041] The second display window (132) may be displayed separately from the first display window (131). When maintenance information is selected from the display section (130), the second display window (132) may be displayed. The second display window (132) can visually display maintenance information regarding maintenance guidelines for equipment diagnosed as having a defect among the equipment equipped in the ship propulsion system (50) as shown in FIG. 3. That is, the second display window (132) can visually display a list of components equipped in the equipment diagnosed as having a defect, the diagnosis results of each component, and maintenance information of the defective component. Therefore, through the second display window (132), the status of each component equipped in the defective equipment and the maintenance information of the defective component can be checked simultaneously.

[0042] Meanwhile, the display unit (130) may further include a third display window (133). The third display window (133) may be displayed separately from the second display window (132) and the first display window (131). When health is selected in the display unit (130), the third display window (133) may be displayed. The third display window (133) may display a health index that quantifies the condition of each of the equipment and the components equipped in each of the equipment, as shown in FIG. 4. That is, the third display window (133) displays the equipment by grouping them, and when one of the groups is selected, the health index of the equipment included in that group is displayed in a radial chart format, and when one of the equipment is selected, the health index of the components equipped in that equipment is displayed in a radial chart format. Therefore, the condition of the equipment and components can be easily checked through the third display window (133).

[0043] The diagnostic unit (110) can receive status information from equipment equipped in the ship propulsion system (50). For example, the diagnostic unit (110) can receive status information that the ship propulsion system (50) collects from each piece of equipment and transmits to the integrated engine control system. The diagnostic unit (110) can diagnose whether an abnormality has occurred in each piece of equipment based on the status information received from the equipment. Thus, the diagnostic unit (110) can identify equipment in a normal state and equipment in which an abnormality has occurred. The diagnostic unit (110) includes an information storage unit (111), a reference generation unit (112), and a judgment unit (113).

[0044] The information storage unit (111) may be a storage medium for storing information. Accordingly, the information storage unit (111) may receive and store status information from equipment. For example, when the equipment provided in the ship propulsion system (50) includes a gas turbine, a reduction gear, a plurality of generators, a plurality of electric motors, and a plurality of propellers, the status information provided by each of the equipment may include shaft speed information, load information, lubricating oil temperature information, and bearing temperature information measured by sensors provided in each of the equipment.

[0045] The reference generation unit (112) can be connected to the information storage unit (111). Accordingly, the reference generation unit (112) can generate a reference value (or baseline) that serves as a criterion for determining whether an abnormality has occurred in each of the equipment by performing regression analysis based on the status information stored in the information storage unit (111). For example, the reference generation unit (112) can perform multiple regression analysis with shaft speed information, load information, and lubricant temperature information transmitted by each of the equipment as independent variables, and bearing temperature information as the dependent variable. That is, it can generate a reference value by estimating a regression line representing the relationship between the independent variables and the dependent transmission and calculating the standard deviation. At this time, the reference generation unit (112) can preprocess the status information stored in the information storage unit (111) before performing the regression analysis to remove abnormal status information and status information measured in an abnormal state. In detail, missing values ​​and status information collected when equipment is off can be removed or deleted from the status information stored in the information storage unit (111), and status information for a preset period can be grouped into a set, and the normality of the corresponding status information set can be verified according to criteria such as skewness, kurtosis, and crest factor for each set. Skewness indicates the degree to which the distribution of data in a density function graph is skewed to the left or right compared to a normal distribution. Kurtosis indicates the degree to which the distribution of data in a density function graph is clustered around the mean value. As the value increases relative to the normal distribution, the distribution clusters around the mean value. The crest factor indicates the ratio of the degree of sharpness of the waveform or the ratio of how much influence the maximum value has. Accordingly, the reference generation unit (112) can compare the kurtosis, skewness, and crest factor of the status information set with a preset reference range, and if it falls outside the reference range, the corresponding status information set can be removed so that it is not used when generating reference values.

[0046] The judgment unit (113) may be connected to the information storage unit (111) and the reference generation unit (112). The judgment unit (113) can determine whether an abnormality has occurred in each of the equipment by comparing the status information transmitted by the equipment to the information storage unit (111) in real time with the reference value. The status information may include a measurement value (e.g., bearing temperature information, etc.) obtained by measuring the status of each component provided in each of the equipment using a sensor. If the difference between the measurement value and the reference value is less than or equal to a preset value, the judgment unit (113) determines that the status of the corresponding component is normal. If the difference between the measurement value and the reference value included in the status information exceeds a preset value, the judgment unit (113) determines that the status of the corresponding component is abnormal. If there is a component with an abnormality among the components provided by the equipment, the status of the equipment is determined to be abnormal, and if there is no component with an abnormality among the components provided by the equipment, the status of the equipment is determined to be normal.

[0047] The processing unit (120) can be connected to the diagnostic unit (110) and the display unit (130). If the diagnostic unit (110) diagnoses that there is equipment that has a malfunction, the processing unit (120) can process the equipment so that it is distinguished from the equipment in a normal state in the configuration diagram displayed by the display unit (130), and process the maintenance information of the equipment so that it is displayed on the display unit (130). Accordingly, the operator of the vessel can quickly identify the equipment with a changed color among the equipment equipped in the vessel propulsion system (50) displayed in the first display window (131) of the display unit (130), and easily identify the equipment diagnosed as having a malfunction and the location of the equipment. The processing unit (120) includes a first processing unit (121) and a second processing unit (122).

[0048] The first processing unit (121) can change the color displayed on the first display window (131) of the equipment that the diagnostic unit (110) has diagnosed as having an abnormality. The first processing unit (121) includes a first verification unit (121a) and a first change unit (121b).

[0049] The first verification unit (121a) can be connected to the diagnostic unit (110) to receive diagnostic results for the equipment. The first verification unit (121a) can verify whether the equipment diagnosed by the diagnostic unit (110) as having an abnormality is equipment included in the configuration diagram. That is, the first verification unit (121a) can identify the equipment diagnosed by the diagnostic unit (110) as having an abnormality and compare it with a list of equipment included in a previously stored configuration diagram. If the equipment is in the list, the first verification unit (121a) determines that the equipment is equipment included in the configuration diagram, and if the equipment is not in the list, the first verification unit (121a) determines that the equipment is equipment not included in the configuration diagram.

[0050] The first change unit (121b) can be connected to receive the verification result of the first verification unit (121a). If there is equipment verified by the first verification unit (121a), the first change unit (121b) can change the color of the equipment displayed in the first display window (131) to a second color different from the first color. For example, the equipment included in the configuration diagram displayed in the first display window (131) includes a gas turbine, a reduction gear, multiple generators, multiple electric motors, and multiple propellers, and if an abnormality is diagnosed in any one of the multiple electric motors, the first change unit (121b) can change the color of the electric motor displayed in the first display window (131) as shown in FIG. 2. Thus, the operator of the vessel can quickly and easily check the equipment with an abnormality through the first display window (131). At this time, the first change part (121b) may use a color with a longer wavelength of light than the first color among visible light as the second color. That is, by using a color with higher visibility than the first color as the second color, it is possible to easily identify equipment that has malfunctioned in the first display window (131).

[0051] In this way, the location of the equipment that has malfunctioned among the equipment equipped in the ship propulsion system (50) can be easily identified. Therefore, the location of the equipment that has malfunctioned can be quickly identified and maintenance can be performed.

[0052] Meanwhile, the first processing unit (121) may further include a second verification unit (121c) and a second modification unit (121d). Accordingly, equipment in a normal state, equipment with an abnormality, and equipment in a state of maintenance can be distinguished and displayed on the first display window (131).

[0053] The second verification unit (121c) can verify the equipment whose color displayed on the first display window (131) by the first change unit (121b) has been changed to the second color. The second verification unit (121c) can verify whether there is any equipment among the equipment displayed in the second color that does not transmit status information after a preset time. It monitors whether the equipment displayed in the second color transmits status information to the integrated agency control system after the set time has elapsed, and if the equipment does not transmit status information, it can determine that the equipment is in a blocked state so as not to transmit status information due to maintenance.

[0054] The second change unit (121d) can be connected to receive the verification result of the second verification unit (121c). If there is equipment verified by the second verification unit (121c), the second change unit (121d) can change the color of the equipment displayed in the first display window (131) to a third color different from the first and second colors. Accordingly, when the equipment displayed in the second color in the first display window (131) is changed to the third color, the operator of the vessel can confirm that maintenance of the equipment has started. When the maintenance of the equipment is completed and status information is received from the equipment, the color displayed in the first color can be changed according to the diagnosis result of the diagnosis unit (110) if it is in a normal state, and the color displayed in the second color can be changed if it is in an abnormal state.

[0055] The second processing unit (122) can find maintenance information of equipment that the diagnostic unit has diagnosed as having an abnormality and output it to the second display window (132). The second processing unit (122) includes a first storage unit (122a) and a first search unit (122b).

[0056] The first storage unit (122a) may be a storage medium for storing information. Accordingly, the list of equipment included in the configuration diagram displayed in the first display window (131) and the maintenance information for each piece of equipment may be matched and stored in the first storage unit (122a) in advance. The maintenance information may include maintenance guidelines and information regarding the source of the maintenance guidelines.

[0057] The first search unit (122b) is connected to the first storage unit (122a) and can be connected to receive diagnostic results for equipment from the diagnostic unit (110). Accordingly, the first search unit (122b) can search for and find maintenance information matching the equipment diagnosed by the diagnostic unit (110) as having a malfunction from the first storage unit (122a). From the maintenance information of the equipment diagnosed by the first search unit (122b) as having a malfunction, only maintenance information related to the component with the malfunction among the components equipped in the equipment may be extracted. The first search unit (122b) can output the searched maintenance information, or the maintenance information of the component extracted from the maintenance information, to the second display window (132) to display it in text form. Therefore, the operator of the vessel can check the equipment with a malfunction through the first display window (131) and easily check maintenance information, such as maintenance guidelines for maintaining the equipment, through the second display window (132). Since maintenance information includes details about the source of the maintenance guidelines, ship operators can easily find and refer to the source materials if they wish to verify the maintenance guidelines in more detail.

[0058] Meanwhile, the second processing unit (122) may further include a second storage unit (122c) and a second search unit (122d). Accordingly, the expected cause of the equipment malfunction can be displayed in the second display window (132).

[0059] The second storage unit (122c) may be a storage medium for storing information. Accordingly, the list of equipment included in the configuration diagram displayed in the first display window (131) and cause information regarding the expected causes that may cause abnormalities in each of the equipment can be matched and stored in the second storage unit (122c) in advance.

[0060] The second search unit (122d) is connected to the second storage unit (122c) and can be connected to receive diagnostic results for equipment from the diagnostic unit (110). Accordingly, the second search unit (122d) can search for cause information matching the equipment diagnosed by the diagnostic unit (110) as having an abnormality from the second storage unit (122c). The second search unit (122d) can output the searched maintenance information to the second display window (132) to display a list of expected causes in text form. For example, the maintenance information may be displayed in the first area of ​​the second display window (132), and the cause information may be displayed in the second area (e.g., the area above the first area) which is separated from the first area of ​​the second display window (132). Therefore, the operator of the vessel can easily check not only the maintenance information of the equipment that has an abnormality but also the cause information that can predict the cause of the abnormality through the second display window (132).

[0061] At this time, the second processing unit (122) may further include a transmission unit (not shown). The transmission unit is connected to exchange information with the first search unit (122b) and the second search unit (122d), and can communicate wirelessly with a terminal held by a mechanic. Accordingly, the transmission unit can transmit maintenance information searched by the first search unit (122b) and cause information searched by the second search unit (122d) to the terminal held by the mechanic. Specifically, it can transmit maintenance information related to the defective component extracted by the first search unit (122b) to the terminal. Therefore, the mechanic can easily check the maintenance information and cause information through the terminal held by themselves and perform maintenance work.

[0062] Meanwhile, the processing unit (130) may further include a third processing unit (123). The third processing unit (123) can calculate a health index based on the result of comparing the status information transmitted in real-time by the diagnostic unit (110) with a reference value, and output it to the third display window (133). The health index may be a value between 0 and 100, and the closer it is to 0, the more maintenance is required, and the closer it is to 100, the less maintenance is required. Accordingly, the greater the difference between the measured value included in the status information and the reference value, the closer the health index of the corresponding component is to 0, and the smaller the difference, the closer the health index of the corresponding component is to 100. In the case of equipment, the health index may be calculated according to the size of the health index of the component provided in each piece of equipment. Accordingly, the health index may be calculated for each component and for each piece of equipment and output to the third display window (133). The third processing unit (133) can calculate and store the health index for each preset period.

[0063] In this way, among the equipment equipped in the ship propulsion system (50), equipment that has malfunctioned can be identified and maintenance information regarding the maintenance guidelines for the equipment can be displayed. Therefore, by checking the maintenance information, equipment that has malfunctioned can be easily maintained.

[0064] Meanwhile, the vessel propulsion system monitoring device (100) may further include an authentication unit (not shown). The authentication unit can verify the account information entered by the vessel operator and the identification items possessed by the vessel operator to verify the access rights to the information assigned to the operator. Accordingly, the authentication unit can display information accessible to the operator through the display unit (130) based on the authentication result. When the vessel operator is authenticated and logged in through the authentication unit, the authentication unit controls the information storage unit (111) to receive status information from the equipment in real time so that the diagnosis unit (110) can start diagnosing the status of the equipment and the vessel operator can check the status of the equipment through the display unit (130). When the vessel operator logs out after the authentication is completed through the authentication unit, the authentication unit controls the information storage unit (111) not to receive status information from the equipment in real time so that the information storage unit (111) does not receive information unnecessarily and the diagnosis unit (110) does not diagnose the equipment unnecessarily.

[0066] FIG. 5 is a flowchart illustrating a method for monitoring a ship propulsion system according to an embodiment of the present invention. Below, a method for monitoring a ship propulsion system according to an embodiment of the present invention will be described.

[0067] A monitoring method for a ship propulsion system is a monitoring method for diagnosing whether an abnormality has occurred in the equipment equipped in the ship propulsion system. Referring to FIG. 5, the monitoring method includes a display process (S110) for visually displaying a configuration diagram of the equipment, a judgment process (S120) for determining whether an abnormality has occurred in each piece of equipment based on status information received from the equipment, and a processing process (S130) for, if there is equipment determined to have an abnormality, processing so that the equipment is distinguished from the equipment in a normal state in the configuration diagram and displaying maintenance information regarding the maintenance guidelines for the equipment.

[0068] At this time, the ship propulsion system monitoring method can be performed by a ship propulsion system monitoring device according to an embodiment of the present invention having the configuration shown in FIGS. 1 and 2. Accordingly, the processes of performing the ship propulsion system monitoring method will be described below with reference to FIGS. 1 and 2. However, the ship propulsion system monitoring method according to an embodiment of the present invention can be performed by a ship propulsion system monitoring device having various configurations, not limited thereto.

[0069] First, the configuration diagram of the equipment is visually displayed (S110). That is, a display unit (130) equipped with a display that can be visually checked by the operator of the vessel may display a first display window (131) for displaying the configuration diagram and a second display window (132) for displaying maintenance information, separated from the first display window (131). For example, if a status is selected in the display unit (130), the first display window (131) may be displayed, and if maintenance information is selected, the second display window (132) may be displayed. The first display window (131) may display the equipment included in the configuration diagram in a first color.

[0070] Next, based on the status information received from the equipment, it is determined whether an abnormality has occurred in each piece of equipment (S120). To this end, the information storage unit (111) can generate a reference value that serves as a criterion for determining whether an abnormality has occurred in each piece of equipment by performing multiple regression analysis based on the stored status information received in advance from the equipment. For example, the reference generation unit (112) can generate a reference value by performing multiple regression analysis with shaft speed information, load information, and lubricant temperature information included in the status information as independent variables and bearing temperature information as a dependent variable, estimating a regression line representing the relationship between the independent variables and the dependent variable, and calculating the standard deviation. Once the reference value is generated, the status information transmitted by the equipment to the information storage unit (111) in real time can be compared with the reference value generated by the reference generation unit (112) to determine whether an abnormality has occurred in each piece of equipment. More specifically, if the difference between the measured value and the reference value included in the real-time status information is less than or equal to a preset value, the judgment unit (113) determines that the state of the equipment is normal, and if the difference between the measured value and the reference value included in the real-time status information exceeds a preset value, the judgment unit (113) determines that the state of the equipment is abnormal. Therefore, when equipment failure occurs, even if accumulated status information does not exist, the state of the equipment equipped in the ship propulsion system (50) can be diagnosed.

[0071] Next, if there is equipment determined to have a malfunction, the equipment is processed so that it is distinguished from equipment in a normal state in the configuration diagram, and maintenance information regarding the maintenance guidelines for the equipment is displayed (S130). That is, the color displayed in the first display window (131) for the equipment determined to have a malfunction is changed to allow the operator of the vessel to recognize the equipment, and maintenance information for the equipment diagnosed as having a malfunction is found and output to the second display window (132) to provide the operator of the vessel with maintenance guidelines for the equipment.

[0072] In order to visually notify the vessel operator of equipment that has malfunctioned, it can be checked whether the equipment determined to have malfunctioned is included in the configuration diagram. If the equipment determined to have malfunctioned is included in the configuration diagram, the color of the equipment displayed in the first display window (131) can be changed to a second color different from the first color. By checking the equipment whose color displayed in the first display window (131) has been changed to the second color, the vessel operator can quickly identify the equipment that has malfunctioned and its location. At this time, the visibility of the second color can be enhanced by using a color with a longer wavelength of light than the first color among visible light as the second color, and the vessel operator can quickly identify the equipment whose color has been changed in the first display window (131). Therefore, the vessel operator can take prompt action to perform maintenance on the equipment.

[0073] In this way, the location of the equipment that has malfunctioned among the equipment equipped in the ship propulsion system (50) can be easily identified. Therefore, the location of the equipment that has malfunctioned can be quickly identified and maintenance can be performed.

[0074] Meanwhile, after the equipment determined to have an abnormality changes the color displayed in the first display window (131) to the second color, the time can be checked to see if a preset setting time has elapsed. After the setting time has elapsed, it can be checked whether the equipment displayed in the second color in the first display window (131) transmits status information. Specifically, after the setting time has elapsed, it can be checked whether the second storage unit (122c) transmits the real-time status information of the equipment to the information storage unit (111). If the equipment displayed in the second color in the first display window (131) does not transmit status information, it can be determined that the equipment is in a blocked state so as not to transmit status information due to maintenance. Accordingly, so that the operator of the vessel can confirm that maintenance of the equipment has started, the color displayed in the first display window (131) of the equipment can be changed to a third color different from the first and second colors. When maintenance of the equipment is completed and status information is received from the equipment, the status of the equipment can be re-diagnosed; if it is in a normal state, the color displayed in the first color can be changed, and if it remains in an abnormal state even after maintenance, the color displayed in the second color can be changed. If the equipment displayed in the second color in the first display window (131) transmits status information after the set time has elapsed, it can be determined that the equipment is not being performed and the status information is continuously being transmitted. Therefore, the equipment can be maintained in the second color in the first display window (131), and the operator of the vessel can confirm through the first display window (131) that maintenance of the equipment has not been performed even after the set time.

[0075] In order to visually provide maintenance information for equipment that has malfunctioned to the ship's operator, maintenance information matching the equipment determined to have malfunctioned can be searched from pre-stored data by matching the list of equipment included in the configuration diagram with the maintenance information for each piece of equipment. The searched maintenance information can be displayed in text form through the second display window (132). Accordingly, the ship's operator can identify the equipment that has malfunctioned through the first display window (131) and easily check maintenance information, such as maintenance guidelines for maintaining the equipment, through the second display window (132). The maintenance information displayed in the second display window (132) includes information regarding the maintenance guidelines and the source of the maintenance guidelines, so that the maintenance guidelines and the source of the maintenance guidelines can be displayed together. Therefore, if the ship's operator wishes to check the maintenance guidelines in more detail, they can easily find and refer to the source material.

[0076] Meanwhile, cause information matching the equipment determined to have a malfunction can be searched from pre-stored data by matching the list of equipment included in the configuration diagram with cause information regarding expected causes that may cause malfunctions in each piece of equipment. The searched cause information can be displayed in the form of text showing a list of expected causes through the second display window (132). For example, maintenance information can be displayed in the first area of ​​the second display window (132), and cause information can be displayed in the second area separated from the first area of ​​the second display window (132). Therefore, the operator of the vessel can easily check not only the maintenance information of the equipment that has a malfunction but also cause information that can predict the cause of the malfunction through the second display window (132).

[0077] At this time, the retrieved maintenance information and cause information can also be transmitted to a terminal held by the mechanic. Therefore, the mechanic can easily check the maintenance information and cause information through their own terminal to perform maintenance work.

[0078] Meanwhile, the display unit (130) may further include a third display window (133) that displays a health index quantified by the state of each of the equipment and each of the components equipped in each of the equipment, and may calculate the health index based on the result of comparing the status information transmitted in real time by the equipment with a reference value during the processing process and output it to the third display window. The health index may be a value between 0 and 100, and the closer it is to 0, the more maintenance is required, and the closer it is to 100, the less maintenance is required. Accordingly, the greater the difference between the measurement value included in the status information and the reference value, the closer the health index of the corresponding component is to 0, and the smaller the difference, the closer the health index of the corresponding component is to 100. In the case of the equipment, the health index may be calculated according to the size of the health index of the component equipped in each of the equipment. Accordingly, the health index may be calculated for each component and for each piece of equipment and output to the third display window (133). In detail, the third display window (133) can display a health index that quantifies the condition of each of the equipment and the components equipped in each of the equipment. That is, the third display window (133) groups and displays the equipment, and when one of the groups is selected, it displays the health index of the equipment included in that group in a radial chart format, and when one of the equipment is selected, it displays the health index of the components equipped in that equipment in a radial chart format. Therefore, the condition of the equipment and components can be easily checked through the third display window (133).

[0079] In this way, among the equipment equipped in the ship propulsion system (50), equipment that has malfunctioned can be identified and maintenance information regarding the maintenance guidelines for the equipment can be displayed. Therefore, by checking the maintenance information, equipment that has malfunctioned can be easily maintained.

[0080] Meanwhile, before visually displaying the configuration diagram of the equipment, the authentication unit can be used to verify whether the user accessing the ship propulsion system monitoring device (100) is the ship operator. That is, the user can verify whether the user is the ship operator through the account information entered by the user or through the items the user possesses. If the user is not the ship operator, the user cannot log in through the authentication unit, and information regarding the ship propulsion system (50) may not be displayed on the display unit (130). If the user is the ship operator, the user logs in through the authentication unit, and information regarding the ship propulsion system (50) can be displayed on the display unit (130). That is, when the ship operator logs in, real-time status information is received from the equipment equipped in the ship propulsion system (50), the status of each piece of equipment is diagnosed, and the diagnosis results can be displayed on the first display window (131) of the display unit (130). Accordingly, the ship operator can easily check the status of the ship propulsion system (50). When the operator of the vessel logs out by ending the state of authentication completed through the authentication unit, the authentication unit controls the information storage unit (111) so that it does not receive status information from the equipment in real time, thereby preventing the information storage unit (111) from receiving information unnecessarily or the diagnostic unit (110) from diagnosing the equipment unnecessarily. Thus, the security of the vessel operation can be improved.

[0082] As such, although specific embodiments have been described in the detailed description of the present invention, various modifications are possible within the scope of the invention, and various combinations between embodiments are also possible.
