The land connection box 110 is a means for receiving power on the land.

As shown in Figure 1, the land connection box 110 is connected to the switchboard. That is, the land access box 110 is configured to receive power onshore through the switchboard and supply it to a ship anchored in a port. This land access box 110 may be fixedly installed on the port pier. A plurality of land access boxes 110 may be connected through one switchboard.

The land connection box 110 is a configuration for supplying power of the land to a ship moored in a port, and a land connection box may be installed at each position at which the ship is moored.

The dispenser 120 is located between the land junction box 110 and the ship, and is provided with a cable for supplying land power, and connects the land junction box and the ship through the cable to supply land power from the land junction box. It is a configuration that mediates to be provided by ship.

The movable cable reel 500 is located between the land junction box 110 and the ship, and is provided with a cable that supplies power to the land. It is a configuration that mediates to provide power to the ship.

Due to the characteristics of the ship, it is anchored adjacent to the port, but it is not parked and stopped at a designated parking line like a car, but is anchored at an approximate position adjacent to the port. For this reason, since the ship is not anchored at the same position, there is a characteristic that it is difficult to anchor adjacent to the land connection box 110.

For this reason, the dispenser 120 equipped with a cable is located between the onshore connection box 110 and the ship, so that the power of the land supplied from the onshore connection box 110 can be easily supplied to the ship.

In addition, the movable cable reel 125 is located between the land connection box 110 and the ship, so that the power of the land supplied from the land connection box 110 can be easily supplied to the ship.

In addition, the land connection box 110 is a device that receives land power through a switchboard, and may be provided with a power connector. One end of the cable provided in the dispenser 120 may be connected through a power connector. Through this, the land junction box 110 may receive land power and supply it with a cable.

Since the land junction box 110 is a device that receives power, the land power through the land junction box 110 should not be leaked, except when the power is actually supplied to the ship through a cable. Accordingly, the land access box 110 may be operated in a power cut-off mode in a state before use.

That is, even if one end of the cable provided in the dispenser 120 is coupled to the power connector, the land junction box 110 may be operated so that land power is not directly supplied through the cable. When the power supply button provided in the land junction box 110 is operated after one end of the cable provided in the dispenser 120 is connected to the power connector of the land junction box 110, when the power cut-off mode is released, the land power is transferred to the cable.

3 and 4, safety fences 410a and 410b may be installed at the lower and upper portions of the dispenser 120. The dispenser 120 is provided with a cable having a predetermined length, and when the cable is combined with the land junction box 110 to supply land power to the ship side, a high voltage flows. Accordingly, safety nets may be installed on the lower and upper portions of the dispenser 120 in consideration of safety of equipment and users.

In addition, a guide portion 420 is formed on the upper end of the dispenser 120. The guide portion 420 is located in the cable assembly, it is possible to withdraw the cable so as to be connected to the ship. The guide unit 420 may be rotated and moved forward and backward by a predetermined angle (for example, within 90 degrees) in the left or right direction based on the direction and distance of the ship's berth.

For this reason, the dispenser 120 may acquire ship-related information through a communication device or a sensor provided in the device. Here, the ship-related information may be at least one of a ship berth direction, a height of a ship, a distance to a ship, and a ship type.

The dispenser 120 may adjust the rotation direction, the forward and backward distances, and the cable take-out distance of the guide unit 420 by using the acquired ship-related information. The dispenser 120 may determine the forward and backward distances of the guide part 420 according to the distance to the ship after rotating the guide part 420 so as to be connectable to the obtained ship berth direction. In addition, the dispenser 120 may adjust the height of the power supply cable based on ship-related information.

The dispenser 120 may move the guide part 420 forward and backward toward the ship berth position in consideration of the length of the cable that can be withdrawn from the guide part 420.

After the guide part 420 is moved forward and backward according to the control of the dispenser 120 and extends in the longitudinal direction, the guide part 420 may withdraw the cable by a predetermined length. At this time, the dispenser 120 may adjust the cable lead length based on ship-related information. That is, the dispenser 120 may differently adjust the cable lead length according to the distance to the ship.

In addition, the dispenser 120 may be separately provided with an elevating member so that the height of the guide portion 420 is fixed or elevated or lowered based on ship-related information.

In FIGS. 3 and 4, it is assumed that the dispenser 120 is fixedly installed at the port pier, and this has been described mainly.

Depending on the ship power supply position, the cable provided in the dispenser 120 may have a long distance to the ship or it may be difficult to fix it. Accordingly, the onshore power supply system 100 according to an embodiment of the present invention may further include a movable cable reel device for extending a cable between the dispenser 120 and the ship.

The movable cable reel equipment 500 is as shown in FIG. 5. The movable cable reel equipment 500 is mounted with a cable reel and may be a device capable of running.

Like the dispenser 120, the movable cable reel equipment 500 may have a guide portion formed thereon. The movable cable reel equipment 500 includes a plurality of cable twist prevention members 520 on one surface of the guide part. The cable may be drawn out/retracted in one direction through the cable twist prevention member 520. In addition, the cable twist prevention member 520 may prevent the cable from being entangled when the guide portion is extended in the longitudinal direction. As shown in FIGS. 5 and 6, a plurality of cable twist prevention members 520 may be configured. In an exemplary embodiment of the present invention, it is assumed that the four cable twist preventing members 520 are configured, and this will be described mainly, but it is natural that the number of the cable twist preventing members 520 may be different.

A first cable twist preventing member to a fourth cable twist preventing member may be formed on one surface of the guide part configured in the movable cable reel equipment 500, respectively. 5 and 6, the cable output from the first cable twist prevention member is output to the output terminal through the input terminal of the second cable twist prevention member, and the cable output from the second cable twist prevention member is third. The cable is output to the output terminal through the input terminal of the cable twist prevention member, and the cable output from the third cable twist prevention member may be output to the ship through the output terminal through the input terminal of the fourth cable twist prevention member.

Therefore, as the one end of the cable provided in the dispenser 120 and one end of the movable cable reel equipment 500 are combined, and the other end of the movable cable reel equipment 500 is coupled with the ship-side power supply connection, the onshore connection box 110 The cable can also be extended so that the onshore power supplied through) is supplied to the ship side.

In addition, the guide part formed in the movable cable reel equipment 500 is also rotated in the left or right direction according to the ship-related information obtained through the communication device or sensor installed in the device, like the guide part of the dispenser 120, in the longitudinal direction. It is natural that you can adjust the forward and backward movement, the height of the guide, and the length of the cable withdrawal. The movable cable reel equipment 500 may use self-acquired ship-related information, and after obtaining ship-related information through a dispenser or server, use it to rotate left or right, move forward or backward in the longitudinal direction, and guide. The height of the part and the cable extension length can be adjusted.

In addition, a first socket or a first plug may be formed at one end of the cable provided in the dispenser 120, and a second socket or a second plug may be formed at the other end of the cable.

An erroneous insertion prevention nose may be formed in the first socket or the first plug and the second socket or the second plug. At this time, the first socket or the first plug and the erroneous insertion preventing nose formed in the second socket or the second plug have different shape positions to distinguish the part connected to the land junction box 110 and the part connected to the ship side. can do.

For example, the nose of the first socket or the first plug may be formed at a first angle (eg, 0 degrees) with respect to the center (see FIG. 7 ). On the other hand, the erroneous insertion preventing nose formed in the second socket or the second plug may be formed at a second angle (eg, 30 degrees) centered (FIG. 8).

As described above, there is an advantage in that the position of the erroneous insertion preventing nose formed in the first socket or the first plug and the second socket or the second plug can be changed, thereby preventing an operator from confused and incorrectly inserting a cable.

In addition, the dispenser 120 may sense the connection of one end of the cable to the power connector of the land junction box 110 and the connection of the other end of the cable to the ship-side power supply connector. The dispenser 120 may cancel the power cut-off mode when one end of the cable is connected to the land junction box 110 and the other end of the cable is connected to the ship-side power supply connector.

That is, the dispenser 120 may be operated in a power cut-off mode in a state before use. Accordingly, even if one end of the cable provided in the dispenser 120 is connected to a land connection box or a ship, power can be prevented from being supplied through the cable.

When it is detected that both ends of the cable are connected to the onshore junction box and the ship-side power supply connection, the power cut-off mode may be released to provide onshore power from the onshore junction box 110 through the cable. have.

Of course, the dispenser 120 may be provided with a separate button for starting or shutting off power supply. For this reason, even if the provided cable is connected to both the land junction box and the ship side, when a button for starting or blocking the corresponding power supply is pressed, power may be provided or cut off to the ship side through the cable.

In addition, when a control command for starting or blocking the power supply is received through a wired/wireless remote controller, the dispenser 120 may control the power to be provided or cut off to the ship side through a cable.

In addition, the dispenser 120 may further include a reader (not shown). For this reason, the dispenser 120 may obtain, as tag information, ship identification information to which a cable is connected through a reader (not shown). Accordingly, the dispenser 120 transmits the acquired ship identification information to the server 130 so that the ship to which the cable is connected for supplying land power can be recognized without a separate input.

The server 130 is a device capable of managing, operating, and diagnosing a ship's onshore power supply system.

To this end, the server 130 may periodically acquire status information from the land access box 110, the dispenser 120, and the movable cable reel 500. Through this, the server 130 can check the real-time status of the plurality of land access boxes 110 and dispensers 120 and the movable cable reel 500 installed in the port.

FIG. 9 shows an example of a screen in which the server 130 visually outputs real-time status of a plurality of land access boxes 110 and dispensers 120 and mobile cable reels 500 installed in a port. In an embodiment of the present invention, in order to facilitate understanding and explanation, it is assumed that the server 130 visualizes and outputs the real-time status of the land access box and the dispenser. For example, it is natural that it may be possible to grasp the status of the switchboard, etc.) in real time (normal status, power supplying, failure status, etc.).

In addition, the server 130 may also visualize and output information of each equipment of the onshore power supply system for ships or each equipment connected (interlocked) with the onshore power supply system. This will be briefly described.

For example, it is assumed that the first ship is receiving onshore power through the first onshore junction box and the first dispenser. The server 130 may obtain identification information of the first ship connected through the first dispenser. In addition, the server 130 may check the connection between the first land connection box and the first dispenser through communication between the first land connection box and the first dispenser. Accordingly, the server 130 recognizes that onshore power is supplied by connecting the first onshore connection box and the first ship through the first dispenser, and monitors the amount of power supplied through the first onshore connection box, The power consumption used by the ship can be monitored.

In addition, when the first land access box or the first dispenser icon is selected through the screen, the server 130 visualizes information on the first ship receiving land power through the corresponding first land access box or the first dispenser. It can also be provided. At this time, the server 130 visualizes the power supply start date, total power consumption, daily power consumption, and power supply end date corresponding to the first ship receiving onshore power through the first land access box or the first dispenser. You can also print it out.

The servers 130 are respectively connected to the onshore power supply system for ships installed at the port pier, and can obtain the power consumption of each ship from the corresponding onshore power supply system.

In addition, the server 130 may monitor the amount of air pollutant reduction of the ship based on the amount of power supplied from the land access box 110 for a certain period (ie, the amount of power used by the ship) via the dispenser.

It is natural that the above example also applies to the mobile cable reel.

The server 130 may perform billing differently in consideration of the amount of air pollutant reduction in billing based on the amount of power used by the ship (power consumption).

This will be described in more detail with reference to FIG. 10.

10 is a flow chart showing a method for monitoring a ship's onshore power supply system according to an embodiment of the present invention. Hereinafter, a description will be made focusing on a method of monitoring the amount of air pollutant reduction.

In step 1010, the server 130 calculates the baseline emissions based on the onshore power consumption used by the ship. Baseline emissions are derived by using the GHG emission factor of electricity generated by oil generation in addition to the amount of onshore power used by the ship at anchor.

This can be expressed as Equation 1.

The server 130 may visualize and output the reduction amount of greenhouse gas emission by ship or as an accumulated total reduction amount.

In addition, the server 130 may perform different charging according to the amount of greenhouse gas emission reduction of each ship when billing according to the amount of power consumed by each ship.

11 is a flow chart showing a management method of the onshore power supply system for a ship according to an embodiment of the present invention.

In step 1110, the server 130 acquires a real-time image of the port pier from the image acquisition device. The server 130 analyzes the real-time captured image to obtain the location of a new moored ship and ship information.

In step 1115, the server 130 acquires connection information from at least one of a land access box, a dispenser, and a mobile cable reel.

When a cable is connected to the power connector provided in the corresponding land connection box, the land connection box may notify the server. In addition, the dispenser may notify the server 130 when the cables are respectively coupled to the land connection box and the ship side.

In step 1120, the server 130 updates the usage status table by using connection information obtained from at least one of a land access box and a dispenser and a mobile cable reel. Through this, the server 130 has the advantage of being able to grasp the status of the land access box and the dispenser and the mobile cable reel connected for use, and the status of the land access box and the dispenser waiting for connection.

In addition, information on the amount of power supplied through each dispenser and the movable cable reel may be recorded in the usage status table. In addition, the server 130 may receive an error event from at least one of a land access box and a dispenser and a mobile cable reel. When an error event is received, the server 130 may manage information on a land access box or/and a dispenser and a portable cable reel that cannot be used due to an error (failure) by updating the error event in the usage status table.

When the usage status table is updated, the server 130 may provide it to the manager terminal. Accordingly, there is an advantage in that the administrator can easily grasp information on the dispenser and the movable cable reel in real time, or the dispenser and movable cable reel that cannot be used due to an error.

In step 1125, the server 130 specifies a ship connected to the corresponding land connection box by using the real-time image or connection information obtained from at least one of the land access box/dispenser/mobile cable reel.

The server 130 interconnects and stores information on ships connected to the land access box/dispenser/mobile cable reel in the usage status table.

In step 1130, the server 130 generates billing information on the amount of power consumption for the ship by referring to the usage status table.
