According to the embodiments of the present invention, by solving the problem that wireless communication is difficult due to the enclosed space in each area inside the ship, data is transmitted through power network communication using the power grid already installed in each area inside the ship.

First, referring to Figures 1 to 3, the ship's internal and external integrated management system 100 (hereinafter, referred to as an integrated management system) according to this embodiment integrated management of the internal and external conditions of the ship 1 It is a system that acquires information on the status of each zone inside and outside the ship, integrates it, and manages it in real time.

To this end, in the integrated management system 100, information on the conditions in each of the inner zones 10 and the outer zones 20 of the ship 1 must be acquired and processed in an integrated manner.

However, in general, the ship 1 can transmit and receive data through wireless communication from the outside, but in the interior of the ship, in order to minimize the expansion of the flooded area in case of damage, each area such as a cabin, cabin, engine room, cargo room, etc. They are designed to be sealed together.

In particular, since each of the areas is partitioned by a sealed door made of a material such as iron or aluminum, or a sealed wall, data transmission and reception through wireless communication may be possible inside each area, but wireless communication with the outside outside each area Data transmission/reception cannot be performed through communication. Accordingly, in the case of the present embodiment, in the case of each of the zones 10 inside the vessel 1, data transmission and reception through wireless communication is performed inside the zones 10, but each zone 10 and the outside With respect to the communication of, it is characterized in that data transmission and reception is performed using so-called power line communication (PLC).

More specifically, the integrated management system 100 includes a plurality of external sensors 110, an external data collection unit 120, a plurality of sub-sensors 200, a plurality of internal sensors 210, and an internal data collection unit. 220, a power network communication module 270 and a data integration module 300.

The external sensors 110 include each of the areas 20 outside the ship 1, for example, the head 21, the stern 22, the outside of the steering room 23, the outside of the chimney 24, etc. Each is installed outside.

That is, the external sensors 110 are located in the first external sensor 111 installed at the head 21, the second external sensor 112 installed at the stern 22, and the outside 23 of the steering room. Like the third external sensor 113 installed and the third external sensor 114 installed outside the chimney 24, it may be individually installed for each zone.

In addition, each of the external sensors 110 senses the state of the ship in each region, and, for example, may sense the vibration state in each region as a vibration sensor. That is, each of the external sensors 110 may be a vibration sensor having a 3-axis accelerometer therein.

Further, it is obvious that the external sensors 110 may be installed in areas requiring additional state sensing in addition to the respective areas outside the vessel described above for example.

In this case, one of the external sensors 110 may be provided in each zone outside of the ship, but when the space of each zone outside is large or when more detailed monitoring for each zone is required, A plurality of external regions may be provided.

The external data collection unit 120 collects sensing signals related to the condition of the ship in each area of the outside 20 measured by each of the external sensors 110.

The external data collection unit 120, as shown in FIG. 1, in order to more easily and effectively collect the sensing data of the external sensors 110, the deck room 30, which is a central part of the ship 1 ), but the location of the external data collection unit 120 may be variously changed.

The external data collection unit 120 collects the sensing signals measured by each of the external sensors 110 using a wireless communication network.

To this end, the external data collection unit 120 includes a wireless network receiving module. In addition, each of the external sensors 110 includes a wireless transmission module for wirelessly transmitting sensing data to the three-axis accelerometer, for example, in the case of a vibration sensor equipped with a three-axis accelerometer.

Thus, the sensing signal for the state of each zone (21, 22, 23, 24) outside the ship, sensed by each of the external sensors 110 (111, 112, 113, 114), through the wireless communication network It is transmitted to the external data collection unit 120.

The internal sensors 210 include each of the zones 10 inside the ship 1, for example, the steering room 18, the cabins and cabins 15, 16, 17, the engine rooms 11, 12, They are installed inside the cargo compartments 13 and 14, respectively.

Each of the internal sensors 210 senses the state of the ship in each zone 10 inside the ship. For example, as a vibration sensor, the vibration state in each zone may be sensed. That is, each of the internal sensors 210 may be a vibration sensor having a 3-axis accelerometer therein.

Further, it is apparent that the internal sensors 210 may be installed in areas requiring additional state sensing in addition to the respective areas inside the vessel described above for example.

For example, as shown in FIG. 4, the internal sensors 210 may be typically installed one by one (211, 212, 213) for each of the inner zones 10 of the ship 1 .

As described above, since each of the inner zones 10 of the ship 1 is partitioned by a sealed door made of a material such as iron or aluminum, or a sealed wall, data transmission/reception through wireless communication cannot be performed. Accordingly, in this embodiment, the internal sensors 210 perform data transmission/reception with the outside using so-called power line communication (PLC) instead of the wireless communication.

Accordingly, the internal sensors 210 may be provided with one (211, 212, 213) for each zone 10 to perform power grid communication. Of course, the number of the internal sensors 210 is not necessarily limited to one, and two or more may be installed in each area if power grid communication with the outside can be performed.

However, in the case of performing communication using power network communication, power consumption is relatively increased, and there is a disadvantage that the speed and amount of data transmission and reception are not excellent compared to wireless communication, so the internal sensor provided in each area 10 Fields 210 may be installed in a minimum number.

On the other hand, the sensing signals for each zone 10 inside the vessel 1 measured by each of the internal sensors 210 are provided to the internal data collection unit 220. In this case, the internal sensors 210 correspond to a representative sensing signal in each internal region 10, that is, an overall sensing signal of each internal region 10, which is the internal data collection unit through the power grid communication. It is provided as 220.

The internal data collection unit 220 collects the sensing signals measured by each of the internal sensors 210 using the power grid communication, and the internal data collection unit 220 is connected to the ship 1 It may be provided in a location where the installed power grid is concentrated.

However, since the internal data collection unit 220 is provided in the deckhouse 30 where the external data collection unit 120 is located, integration of the internal data and the external data can be more easily performed. , But is not limited thereto.

Meanwhile, in this embodiment, the internal data collection unit 220 collects sensing signals measured by the internal sensors 210 through the power network communication, and such power network communication is performed through the power network communication module 270. Is implemented.

That is, the power network communication module 270 includes a wireless receiver 230, a communication module 240 and an integrated receiver 260.

The wireless receiver 230 receives wireless sensing signals from internal sensors 210 provided in each area of the interior 10 of the ship 1, and the sensing signals of the internal sensors 210 It includes a wireless receiving module for receiving. Meanwhile, the internal sensors 210 also include, for example, a vibration sensor equipped with a 3-axis accelerometer, a wireless transmission module for wirelessly transmitting sensing data to the 3-axis accelerometer, and the wireless receiver 230 Sends the signal sensed with ).

In the present embodiment, in the inner zones of the ship 1, only wireless communication from each zone to another zone is blocked, but wireless communication is not blocked within each zone. Accordingly, the internal sensors 210 perform wireless communication with the wireless receiver 230 located in each area including a wireless transmission module.

That is, the first internal sensor 211 wirelessly provides a sensing signal to the first wireless receiving unit 231 provided in the corresponding area, and the second internal sensor 212 is a second wireless receiving unit 232 provided in the corresponding area. ) To wirelessly provide sensing signals.

The communication module 240 is electrically connected to the wireless receiver 230, one end is electrically connected to the wireless receiver 230, and the other end is pre-installed for each zone inside the ship (1). It is electrically connected to the power line 250, that is, a power supply line.

In this case, the power line 250 may be exposed to each area inside the ship 1 in the form of an outlet, and accordingly, the communication module 240 may be electrically connected to an outlet exposed in each area. have.

Accordingly, sensing information of each sensor received through the wireless receiver 230 is provided to the integrated receiver 260 along the power line 250 through the communication module 240.

That is, the first communication module 241 provides the sensing signal received by the first wireless receiver 231 to the integrated receiver 260 through the first power line 251, and the second communication module 242 The sensing signal received from the second wireless receiver 232 is provided to the integrated receiver 260 through the second power line 252.

That is, the integrated receiving unit 260 receives the sensing signals in each area of the vessel provided along each power line 250 through each communication module 240 by integrating.

The integrated receiving unit 260 is connected to the power lines already installed on the ship, that is, the power lines that are integrated and drawn out, and the integrated receiving unit 260 is provided in each of the areas inside the ship 1 thus received. All of the sensing signals of are received and provided to the internal data collection unit 220.

Thus, the internal data collection unit 220 collects sensing signals in each area of the integrated vessel 1.

As described above, the external data collection unit 120 collects sensing signals for the state of each zone 20 outside the vessel 1 measured by each of the external sensors 110, and collects the internal data. The unit 220 collects sensing signals for the states of each of the zones 10 inside the vessel 1 measured by each of the internal sensors 210.

In addition, the sensing signals collected in this way are provided to the data integration module 300, respectively.

On the other hand, in this embodiment, a plurality of the sub-sensors 200 are provided for each of the zones 11, 12, 13 of the interior 10 of the ship 1.

That is, as shown in Figure 4, for example, a plurality of sub-sensors 201 in the first zone 11 (engine room), the first zone 11 around the internal sensor 211 of the first zone ) May be uniformly disposed inside, and this is the same for the second zone 12 and the third zone 13, respectively, so that a plurality of sub-sensors 202 and 203 of the corresponding zone are respectively ) Can be arranged around the center.

In this case, FIG. 4 illustrates that the internal sensor 210 is disposed in the center of each zone, and the sub-sensors 200 are uniformly arranged around the internal sensor, but is not limited thereto, and the internal sensor and The positions of the sub-sensors can be variously changed.

However, at least two of the sub-sensors 200 may be arranged at uniform intervals in each region or at various locations in each region.

The sub-sensors 200 are the same as the internal sensor 210, for example, as a vibration sensor equipped with a 3-axis accelerometer, the vibration state at each location, that is, within each zone of the ship It is possible to sense the vibration state at various locations in

That is, if about one internal sensor 210 is located in each region, and provides a representative sensing signal for the vibration state of the corresponding region, the sub-sensors 200 are at least two or more in each region. By this location, sensing signals at various locations within a corresponding area are measured, which corresponds to detailed sensing signals for each location in each area.

Therefore, the overall vibration state in each zone 10 inside the ship 1 is measured by the internal sensor 210, and the detailed vibration state in each zone 10 is determined by the sub-sensor 200. Is measured.

However, as shown in Fig. 4, only through the internal sensor 210 in normal or general circumstances, only a signal for the overall vibration state in each zone 10 inside the ship 1 is transmitted, and the ship ( 1) When it is determined that the state of a specific area inside is abnormal, as shown in FIG. 5, a signal measured through the sub-sensor 200 for a detailed vibration state in the corresponding area is transmitted.

On the other hand, as described above, in the inner zones of the ship 1, only wireless communication from each zone to another zone is blocked, and wireless communication is not blocked within each zone.

Accordingly, the sub-sensors 200 in the present embodiment may perform wireless communication with the internal sensor 210 of a corresponding area or the wireless receiver 230 of a corresponding area. That is, the sub-sensors 200 provide the sensing signals measured at each location to the internal sensor 210 through wireless communication and provide the sensing signals to the wireless receiver 230 through the internal sensor 210, or It may be provided directly to the wireless receiver 230 through wireless communication.

In this way, the signals measured by the sub-sensors 200 provided to the wireless receiver 230 are the same as the signals provided to the wireless receiver 230 from the internal sensors 210, using the power grid communication described above. Thus, it is collected by the internal data collection unit 220.

Thus, the data integration module 300 includes sensing signals of the external sensors 110 collected through the external data collection unit 120 and the internal sensor collected through the internal data collection unit 220 In case of the field 210 or an emergency situation, the sensing signals of the sub-sensors 200 are synchronized and integrated.

More specifically, the data integration module 300 includes a data integration unit 310, a signal processing unit 320, and a real-time monitoring unit 330.

The data integration unit 310 includes sensing signals of the external sensors 110 collected through the external data collection unit 120 and the internal sensors collected through the internal data collection unit 220 ( 210) or in case of an emergency situation, the sensing signals of the sub-sensors 200 are synchronized.

Since the sensing signals collected through the external data collection unit 120 are signals received through a wireless communication network, and the sensing signals collected through the internal data collection unit 220 are signals received through power network communication, Even if a signal is generated at the same time, there may be a difference in time to be collected, and there may be a difference in the format of the received signals or the amount or type of data.

Accordingly, the data integration unit 310 synchronizes the difference in time, amount, and type of data as described above with each other, so that the sensing signals of the external sensors 110 and the internal sensors 210 Alternatively, all of the sensing signals of the sub-sensors 200, sensing time, and amount or type of signals are matched and integrated.

Thus, the sensing signals of the external sensors 110 and the sensing signals of the internal sensors 210 or the sub-sensors 200 are integrated as sensing signals for each area, and whether the sensing signals of the inner area are It is not possible to distinguish whether it is a sensing signal from an outside area.

The signal processing unit 320 performs data processing on the sensing signals in order to obtain necessary information from the integrated sensing signals.

For example, if the sensing signals are signals related to vibration characteristics, the signal processing unit 320 performs filtering to remove noise from the sensing signals so that the vibration characteristics of the vessel can be better identified, or Various signal processing can be performed, such as extracting only signals of a specific frequency range so that only the vibration characteristics of the frequency range can be recognized.

On the other hand, in the present embodiment, the data integration unit 310 and the signal processing unit 320 are separated from each other to perform synchronization and processing on data. However, the data integration unit 310 and the The signal processing unit 320 may be integrated with each other to perform data processing while synchronizing the sensing signal.

As described above, when synchronization and data processing for the sensing signal through the data integrating unit 310 and the signal processing unit 320 are terminated, the real-time monitoring unit 330 is based on the processed data. The condition is monitored in real time for each zone of the outside 20 and the inside 10 of the ship 1.

For example, if the sensing signal is a signal for a vibration state in each area, the real-time monitoring unit 330 is configured to vibrate in each area of the outside 20 and the inside 10 of the ship 1 The condition can be monitored, and problems in the area can be checked in real time through detection of unusual vibration conditions and necessary actions can be taken.

That is, in the real-time monitoring unit 330, first, based on the signals provided from the internal sensors 210, in particular, the vibration state in each area of the interior 10 of the ship 1 Overall monitoring, but if it is determined that the vibration condition in a specific area is abnormal or abnormal, based on the signals provided from the sub-sensors 200 in the corresponding area, more detailed and precise vibration conditions for the corresponding area are monitored. can do.

Thus, through detection of unusual vibration conditions, problems in the area can be checked in real time and necessary actions can be taken.

6 is a flowchart illustrating an integrated management method using the integrated management system of FIG. 1. 7A and 7B are images showing an example of integrated monitoring of the overall vibration mode of the ship by monitoring vibration characteristics in each zone of the ship of FIG. 6. FIG. 8A is an image of an example of monitoring the vibration characteristics of a specific area by monitoring the vibration characteristics of each area of the ship of FIG. 6, and FIG. 8B is an example of specifically monitoring the vibration characteristics of the'A' area of FIG. 8A. This is the image shown.

Referring to FIG. 6, in the integrated management method of the inside and outside of the ship using the integrated management system 100 described with reference to FIGS. 1 to 3, first, the plurality of external sensors 110 ), the sensing signal is measured in each of the regions 20 outside of (step S10).

In addition, the sensing signals measured in each of the external areas 20 are transmitted to the external data collection unit 120 using a wireless network, whereby the external data collection unit 120 receives the sensing signals. It collects (step S20).

Meanwhile, the plurality of internal sensors 210 measure sensing signals in each of the zones 10 inside the ship 1 (step S30).

In addition, the sensing signals measured in each of the inner regions 10 are transmitted to the internal data collection unit 220 using power network communication, whereby the internal data collection unit 220 receives the sensing signals. It collects (step S40).

In this case, as a specific method in which sensing signals for the inner zones 10 are provided to the internal data collection unit 220, a power network communication method through the power network communication module 270 has been described in detail above.

Thereafter, the data integration unit 310 synchronizes the collected sensing signals of each of the external regions 20 and the sensing signals of the internal regions 10 with each other (step S50), and the external sensor The sensing signals of the s 110 and the sensing signals of the internal sensors 210, sensing time, and the amount or type of signals are all matched and integrated.

Thereafter, the signal processing unit 320 performs data processing on the sensing signals in order to acquire necessary information from the synchronized and integrated sensing signals (step S60), and processes the data into necessary data.

Thus, the real-time monitoring unit 330 monitors the conditions in real time for each zone of the outside 20 and the inside 10 of the ship 1 based on the processed data (step S70). .

For example, as shown in Figs. 7A and 7B, the real-time monitoring unit 330 synchronizes and integrates the measurement results for each area of the outside 20 and the inside 10 of the ship 1 And by performing data processing, it is possible to grasp the overall vibration state or vibration mode of the ship 1.

Thereafter, the condition is monitored in real time, and it is determined whether the condition in each zone outside or inside of the ship 1 is normal (step S80).

Thus, if the state of each zone is normal, monitoring may be continued in real time, or monitoring may be terminated for a predetermined time (step S110).

On the contrary, when the condition is monitored in real time, in particular, if it is determined that the condition in a specific area inside the vessel 1 is abnormal (step S80), the sub-sensors 200 in the area determined to be abnormal are The sensing signal at the corresponding position is measured (step S90).

Thereafter, the sensing signals of the sub-sensors 200 measured at each location in the corresponding area are provided through the internal sensor 210 of the corresponding area or directly to the wireless receiver 230 of the corresponding area, and the wireless It is collected from the receiving unit 230 to the internal data collecting unit 220 through power grid communication (step S100).

Thereafter, through the synchronization step (step S50) and the data processing step (step S60), the real-time monitoring unit 330 monitors the vibration characteristics (step S70).

That is, as shown in FIG. 8A, as a result of monitoring the vibration condition in real time, if it is determined that the condition in the specific area A inside the vessel 1 is abnormal, the sub-sensor for the corresponding area A Through the sensing result using these, as shown in FIG. 8B, the vibration state of the corresponding region A can be derived in more detail and monitored.

By performing such real-time monitoring, it is possible to diagnose condition abnormalities in real time in each area outside or inside of the actual ship 1, and if necessary, in particular, more detailed condition abnormalities in a specific space inside can be diagnosed in real time. In addition, such an abnormality in real-time condition can be diagnosed and safety inspection and repair of the corresponding area can be performed at the same time, thereby improving the safety, reliability, and durability of the ship.

According to the embodiments of the present invention as described above, by solving the problem that wireless communication is difficult due to the airtight space in each of the inner zones of the ship, the power grid communication is performed using the power grid already installed in each of the inner zones. By transmitting data, it is possible to obtain sensing data necessary for monitoring of the ship from each zone inside the ship, and through this, monitoring and monitoring of each zone inside the ship is possible.

However, data transmission is possible from the outside of the ship through wireless communication, which is difficult to synchronize with the data transmitted through the power network communication, so the data is synchronized and processed through the data integration module, thereby It is possible to implement real-time monitoring of ship conditions such as vibration characteristics in each of the areas.

In particular, each zone inside the ship is designed to be sealed to each other due to the characteristics of the ship, but since the power grid is provided for each zone, the above data transmission and integration can be implemented, and the data on the interior zone in the newly designed ship A separate wired communication network for transmission may not be installed, and data transmission can be performed even on a pre-manufactured ship, thereby saving time or cost for implementing the real-time monitoring system.

In this case, each zone inside the ship is equipped with internal sensors to measure and provide representative sensing signals for the vibration characteristics of the zone, but if an abnormality in the vibration characteristics of the zone is found, a plurality of them are provided in the zone. Detailed sensing signals for vibration characteristics may be measured and provided through sub-sensors. Therefore, it is possible to minimize power consumption and minimize the amount of measurement data through monitoring of the entire internal area using an internal sensor in normal times, and when a specific abnormality occurs, detailed information about the area can be selected through a sub-sensor. Because it can be obtained, more accurate and precise monitoring can be performed.

Meanwhile, since the sub-sensors can transmit data through wireless communication between the internal sensor and the corresponding area, the internal sensor can be installed at various locations in the corresponding area, as well as the measurement data can be more effectively transmitted.

In this way, it is possible to acquire information on the condition of the ship, such as individual vibration characteristics for each zone inside and outside the ship, and integrate and manage it into one real-time monitoring system, so problems such as vibration abnormalities in a specific area Since the problem can be solved by immediately sensing, the safety, reliability, and durability of the ship can be further improved.
