Ships are generally expensive products of engineering to order (ETO) methods that are designed and produced to meet the needs of specific customers. For this reason, production information is important to producers in the design of the product, and information on the entire life cycle from maintenance to disposal to recycling is important to ship owners.

In particular, since maintenance of vessels is not a manufacturer but an operator or an inspection agency, MOL (Middle Of Lifecycl) ships are generally designed and manufactured to meet the needs of specific customers by using the ETO (Engineering To Order) For this reason, it is important for producers to have information on the entire life cycle, from production information to design, to shipowners to maintenance, disposal and recycling.

Next, the configuration of the ship parts life cycle management system according to the embodiment of the present invention will be described in detail with reference to Figs. 9 to 11. Fig.

FIG. 9 is a block diagram illustrating a configuration of a ship parts life cycle management system according to an embodiment of the present invention. FIG. 10 is a block diagram illustrating a configuration of a main terminal of a ship parts life cycle management system according to an embodiment of the present invention. And FIG. 11 is a block diagram illustrating a configuration of a sub terminal of the ship parts life cycle management system according to an embodiment of the present invention.

The ship parts life cycle management system according to an embodiment of the present invention may include one or more sub-terminals, a main terminal 200, and one or more user terminals.

9 shows that one or more sub-terminals are composed of five sub-terminals, and a sub-terminal including sub-terminals 1 to 5 (110, 120, 130, 140, 150) .

In addition, the sub terminal plays the role of transmitting the change status information of the parts to the main terminal 200 in real time based on the status information of the parts forming the ship and the input inputted by the operator. Specific functions of the sub terminal will be described in detail below with reference to FIG.

In addition, the main terminal 200 receives the parts information collected through the sub terminal, calculates and stores the remaining service life of the parts based on the related information, displays the stored remaining service life information, provides related information to the user, So that the user can easily grasp the part status and information related to the ship anywhere.

That is, the user in the ship can confirm the service life information of the main part through the main terminal 200 provided in the ship, but can confirm the life information or the like in another space in the ship where the main terminal 200 is not provided or outside the ship A user terminal can be equipped with the user terminal, and the users related to the ship can easily grasp the life information and the like of the major parts of the ship without being attached to the place.

In addition, one or more user terminals may be provided. As shown in FIG. 9, three user terminals (user terminal 1 310, user terminal 2 320, and user terminal 330) may be provided .

The main terminal 200 or the user terminal informs the user of such an alarm type when the remaining life of the main parts in the ship calculated by the main terminal 200 reaches a certain level, .

Next, the configuration of the main terminal 200 of the ship parts life cycle management system according to the embodiment of the present invention will be described in detail with reference to FIG.

10, the main terminal 200 includes a storage unit 210, a life calculation unit 220, a control unit 230, and a display unit 240.

The storage unit 210 stores basic state information including the basic life span of the part, three-dimensional model information of the ship, inspection and authentication information, and the like. Here, the basic state information includes basic lifespan information for each part, basic rotation number change range, basic temperature change range, basic pressure change range, basic current change range and basic appearance change range information for determining the service life of the component .

That is, each information included in the basic state information takes into account the characteristics of the main components in the ship. For example, in the case of a propeller, an engine or a motor which is a main component in a ship, In order to determine the remaining life of the propeller, the engine or the motor, the basic state information should have a range of rotational speed in the steady state.

Further, in the case of a component in which a temperature change (such as a fuel storage tank) is a main factor for determining the remaining service life, a temperature range in which a stable state is maintained becomes basic state information of the component, Etc.) becomes the basic state information of the component in the case of the component which is the main factor for determining the remaining service life, and the current state change (the electronic or electric part to which the current is applied) In the case of a component which is the main factor determining the remaining life of the component, the appropriate current value range is the basic state information of the component, and in the case of the component whose appearance change (crack, etc.) It is assumed that the size and the range of the cracks, etc., are the basic state information of the relevant parts, which is the allowable range of stability.

In addition, the service life calculating unit 220 compares the status information of the parts transmitted from the sub terminal and the change status information with the basic status information, and then calculates the remaining service life of the corresponding part. Here, the main components constituting the ship refer to the parts in which one or more of the change in the number of revolutions, the temperature change, the pressure change, the current change, and the appearance change according to the use occur.

The life calculation unit 220 compares the basic state information of each component with the measured value measured at the sub terminal to calculate the remaining service life of the component.

Specifically, the service life calculating unit 220 calculates first service life information, which is service life information related to the number of revolutions of the component including the rotating means, and calculates second service life information, which is temperature-related service life information of the component, And the third life time information, which is the pressure-related life time information of the component in which the pressure change occurs, calculates the fourth life time information which is the pressure-related life time information of the component in which the current change occurs, And fifth life span information which is appearance-related life span information.

The life calculating unit 220 may calculate a remaining service life of the component by assigning a weight to at least one of the first service life information and the fifth service life information. In other words, the life calculation unit 220 can calculate the remaining service life of the component by weighting the characteristics that particularly affect the service life of the component in consideration of the characteristics of the components in the ship.

Also, the service life calculating unit 220 can calculate the remaining service life of the component based on the average value of the first service life information to the fifth service life information.

As described above, each of the major components constituting the ship has one or more check items (five pieces of status information), and the remaining service life is collectively determined according to the results of the check items (first service life information to fifth service life information) Can be calculated.

In addition, the service life calculating unit 220 can calculate the remaining service life of the component so that the service life of the component is inversely proportional to the number of maintenance times included in the change state information. That is, the life calculating unit 220 may calculate the remaining service life so that the remaining service life of the corresponding component increases as the number of times of maintenance and repair increases, considering not only the first service life information to the fifth service life information but also the maintenance and repair times.

Also, the display unit 240 displays the information stored in the storage unit 210 and the remaining life information of the parts calculated by the life calculation unit 220, to the user.

The control unit 230 controls the display operation of the display unit 240 and controls the storage unit 210 to store the remaining part life information calculated by the life calculating unit 220.

Next, a configuration of a sub-terminal which is a configuration of a ship parts life cycle management system according to an embodiment of the present invention will be described in detail with reference to FIG.

As described above, the sub-terminal 100 may be provided with one or more components corresponding to the number of components in the ship.

Specifically, the sub terminal 100 includes a first sensor 101 for measuring the number of revolutions, a second sensor 102 for measuring temperature, a third sensor 103 for measuring pressure, a fourth sensor A second sensor 104 and a fifth sensor 105 for measuring the shape of the part.

The first sensor 101 for measuring the number of revolutions is a sensor for measuring the number of revolutions of the component provided with the rotating means, and may be specifically provided in the form of a torque sensor, a tachometer, or the like.

In addition, the second sensor 102 for measuring the temperature may be provided in the form of a general industrial thermometer, which measures the internal temperature or the external temperature of the component, which is considered to be an important factor in determining the remaining service life.

The third sensor 103 for measuring the pressure measures the internal pressure or the external pressure of the part, which is considered to be an important factor for determining the remaining life of the pressure change. In an embodiment, the third sensor 103 measures the pressure of the gas or fluid, And measuring the magnitude of the pressure received.

In addition, the fourth sensor 104 for measuring the current measures the applied current of the part and the current in the load, which are considered to be important factors in determining the remaining lifetime of the current, and in the form of a general multimeter .

The fifth sensor 105 for measuring the shape of the part measures the degree of change in the shape of the part, which is considered to be an important factor in determining the remaining service life of the part, by changing the crack or the external shape. (Such as a camera) capable of measuring changes.

Particularly, by using the fifth sensor 105, an external shape image or an image of the corresponding part is obtained, which is used as a measurement value for comparison with the external shape image of the corresponding part. In other words, the external shape change can be judged by comparing the images based on the vulnerable part where the external shape change (cracks, etc.) may occur generally by comparing the images to determine whether the external shape is changed. This comparison process is performed in the life calculating unit 220.

The life calculating unit 220 can calculate the first life time information based on the difference between the basic rotation speed change range of the component and the rotation speed of the component measured by the first sensor 101, The second life information can be calculated based on the temperature difference of the component measured by the second sensor 102. Based on the basic pressure change range and the pressure difference of the component measured by the third sensor 103, 3 lifetime information and calculates the fourth life span information based on the difference between the basic current change range and the current value of the corresponding part measured by the fourth sensor 104, The fifth life span information can be calculated on the basis of the shape difference of the parts measured by the five sensors 105. [

If the remaining life of the component calculated by the life calculating unit 220 is less than a predetermined value of 30% of the basic life span of the component, the control unit 230 determines that the basic rotation speed change range has been measured by the first sensor 101 When the temperature of the component measured by the second sensor 102 deviates from the basic temperature change range and the pressure of the component measured by the third sensor 103 deviates from the basic pressure change range, When the current of the component measured by the fourth sensor 104 is deviated from the basic current change range and when the basic outline change range is out of the shape of the component measured by the fifth sensor 105, . The control unit 230 can control the movement of the ship according to the information calculated by the life calculation unit 220. There are various ways to control the movement of the ship, for example, to prevent the ship from starting.

The life calculating unit 200 can give a signal to the controller 230 when the basic state change range is out of one of the number of revolutions, temperature, pressure, current, and shape of the component. If the basic state change range is out of one of the number of revolutions, temperature, pressure, current and shape of the part, it may be a failure or an abnormality of the part.

In addition, the ship parts life cycle management system may further include a marine management unit terminal (not shown).

The main terminal 200 or the user terminal may set the basic rotation rate change range to a value smaller than a predetermined value that is 30% of the basic service life of the part, calculated by the life calculation unit 220 one day before departure of the ship, When the number of revolutions of the component measured by the first sensor 101 is out of the predetermined range and the temperature of the component measured by the second sensor 102 is out of the basic temperature change range, When the pressure of the measured component deviates, when the current of the component measured by the fourth sensor 104 is deviated from the basic current changing range and when the shape of the component measured by the fifth sensor 105 is out of the basic contour changing range The state information of the ship can be transmitted to the marine management terminal (not shown).

Such a configuration may serve as a safety device to prevent a ship from departing when an abnormality occurs in the part, thereby enabling safe operation. It is possible to prevent the occurrence of an accident due to a problem in parts during operation.

In addition, if such a problem occurs even before the departure day 1, the marine management department will be notified of the problem and the unauthorized departure can be prevented beforehand, and the problem can be promptly solved.

In addition, the sub terminal of the sub terminal 100 may measure the pressure at the lower end of the load cell by the third pressure sensor 103, if the pressure exceeds the ship load standard or the pressure at the lower end of the load cell is different It is possible to control the movement of the ship through the control unit 230.

The third pressure sensor 103 of the sub terminal provided in the load cell of the sub terminal 100 can measure the pressure of the load.

The control unit 230 may control the ship so as to limit the movement of the ship in response to a signal exceeding the ship load standard or when the left and right pressures at the lower end of the load cell are different.

There are various ways to control the movement of the ship, for example, to prevent the ship from starting.

When the main terminal 200 or the user terminal exceeds the ship load reference before departure, or when the left and right pressures of the lower part of the load cell are different, information is received by the sub terminal 100 and the state of the ship Information can be transmitted.

Such a configuration may serve as a safeguard so that the ship can not depart from the ship when the ship's load standard is exceeded and safe operation is possible. It is possible to prevent the load from being overturned due to the weight or balance of the load during operation.

In addition, if such a problem occurs before departure, the marine management department will be notified of the problem so that the unauthorized departure can be prevented beforehand, and the problem can be promptly solved.

Finally, the operation of the ship parts life cycle management system according to the embodiment of the present invention will be described in detail below with reference to the flowchart of FIG.

FIG. 12 is a flowchart illustrating an operational process of the ship parts life cycle management system according to an embodiment of the present invention.

12, the ship parts life cycle management system according to an embodiment of the present invention first collects part status through one or more sensors provided in the sub terminal 100. [ That is, the part state measured at each part may include at least one of the number of revolutions, temperature, pressure, current, and shape (S601). Then, the state information of the corresponding parts collected through the life calculating unit 220 of the main terminal 200 is compared with the basic state information of the previously stored corresponding parts (S602). Specifically, the difference between the basic state information (including the basic life span information) of the relevant part and the state value, which is actually measured value, is calculated, and the life information of the corresponding part is calculated based on the difference value (S603). Specifically, the service life information of the component may include the first service life information to the fifth service life information. That is, the first service life information is the service life information based on the change in the number of revolutions, the second service life information is the service life information based on the temperature change, the third service life information is the service life information based on the pressure change, And the fifth life span information is life span information based on a change in the external shape of the part.

The final remaining service life of the component is calculated on the basis of the lifetime information calculated above (S604). That is, the final remaining service life can be calculated by weighting the characteristics to be considered particularly in the part or by calculating the average value of each service life information.

Then, the calculated remaining life is compared with a pre-stored value in the storage (S605). That is, it is determined whether the calculated remaining life is less than a predetermined value (30% of the basic service life of each component). Here, the predetermined value is a value indicating a maintenance and repair or replacement period, and can be determined within a range of 40% to 90% of the basic service life.

If the calculated remaining service life is less than the predetermined value, it is determined that the remaining service life of the component is short and an alarm is provided so that the user can check the calculated remaining service life (S606). Here, the form of the alarm may be a form in which a warning phrase is visually provided to the user so that the part can be visually checked, or a form in which the user is informed by a warning sound that the corresponding part can be checked can be adopted.

If the calculated remaining service life is equal to or greater than the predetermined value, it is determined that the remaining service life of the component is still within the stable range, and the process returns to the step of measuring the status of the component (return to S601).

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It will be understood. The embodiments described above are therefore to be considered in all respects as illustrative and not restrictive.
