If the control signal is not received from the main hub 130 for a predetermined time when the variable frequency drive VFD starts driving based on the control signal received through the communication units 410, 510, 610, 710, 810 and 910, It is preferable to control the variable frequency drive (VFD) so as to operate at a predetermined maximum operation output value, that is, an output value necessary for the maximum operation of the variable frequency drive (VFD).

Here, the communication units 410, 510, 610, 710, 810 and 910 may be provided in the form of an Ethernet HUB using the TCP / IP protocol.

The panel unit includes a first variable frequency drive 420 for controlling the operation of a seawater pump for pumping seawater flowing from the outside of the ship according to a control signal received from the main hub 130 and supplying the seawater to the heat exchanger A second variable valve for controlling driving of a fresh water pump for discharging fresh water heated in accordance with cooling of the engine of the ship in accordance with a control signal received from the main hub 130 to the heat exchanger; A second starter panel 500 including a frequency drive 520 and a lubricant pump 500 for pumping lubricant contained in the oil pan inside the engine of the ship in accordance with control signals received from the main hub 130, A third starter panel 600 including a third variable frequency drive 620 for controlling the drive of the main shaft 130, A fourth starter panel 700 including a fourth variable frequency drive 720 for controlling the driving of the vacuum condenser installed adjacent to the re-stored cargo; and a fourth starter panel 700 for controlling the operation of the engine room in the ship according to the control signal received from the main hub 130.

Hereinafter, an algorithm performed by the integrated controller 110 according to the present invention will be described with reference to FIGS. 2 to 4. FIG.

Referring to FIG. 2, the integrated control unit 110 receives the stop state information of the engine of the ship through the ship automation system 300 (S210), and controls the first variable frequency drive 420, A first control signal for setting a minimum operation set value necessary for operation of the seawater pump, the fresh water pump and the engine room ventilation fan corresponding to each of the variable frequency drive 620 and the fifth variable frequency drive 820, (S220), and control the main hub 130 to transmit the generated first control signal to the first starter panel 400, the third starter panel 600, and the fifth starter panel 800 (S230).

In this case, if the at least two seawater pumps or the fresh water pumps are provided, the first control signal may be used instead of setting the minimum operation set values of the seawater pump, the fresh water pump and the engine room ventilation fan to be lower At least two seawater pumps or one of the fresh water pumps installed in the ship may be stopped to induce maximum energy saving in the ship.

For example, if there are two seawater pumps and one fresh water pump, the integrated control unit 110 generates a first control signal for stopping one seawater pump in step S220, And if the two fresh water pumps are provided, it is possible to generate a first control signal for stopping one seawater pump and the fresh water pump in step S220.

If a predetermined pressure sensor is installed in the engine compartment in which the engine room ventilation fan is installed, the first control signal is transmitted to the main hub 130 through the fifth communication unit 810 in real time, (Hereinafter referred to as 'proportional control') is a proportional control for maintaining the reference pressure (hereinafter, referred to as PID control (proportional integral differential control ) To control the air supply amount in the engine room.

When the second control unit 110 receives the stop state information of the engine of the ship through the ship automation system 300 in step S210, (S240), and control the main hub 130 to transmit the generated second control signal to the second starter panel 500 (S250).

At this time, the second control signal can maximize the energy saving by allowing the third variable frequency drive 620 to perform the low speed operation in the minimum pressure range for the predetermined time before stopping the lubricant pump.

If a predetermined pressure sensor for measuring whether or not the oil filter is clogged is provided at the front and rear of the oil filter installed at the outlet side of the lubricating oil pump, The integrated controller 110 transmits the measurement value to the main hub 130 and the integrated controller 110 determines that the oil filter is clogged based on the measured value received from the main hub 130, A warning message indicating clogging of the oil filter can be displayed.

If a predetermined pressure sensor is installed at the outlet of the pump and at the front / rear end of the filter, the respective measured values by the pressure sensor are transmitted to the main hub 130 in real time via the second communication unit 510, When the difference is greater than a predetermined threshold value, that is, when it is determined that the performance of the pump is deteriorated, the integrated controller 110 controls the display unit 130, which will be described later, A warning message indicating that a problem has occurred in the pump can be displayed through the controller 120.

In this case, the operator can quickly recognize whether the filter is clogged or whether the pump is in trouble, and can take immediate follow-up measures, thereby preventing the occurrence of a major accident.

3, when the integrated control unit 110 receives status information indicating the start of the unloading operation of the cargo loaded in the ship through the ship automation system 300 (S310), the fourth variable The frequency drive 720 performs proportional control in which the pressure value measured by the pressure sensor attached to the body of the vacuum condenser maintains the preset reference pressure or is measured by the temperature sensor installed at the seawater outlet side of the vacuum condenser (S320) and controls the main hub 130 to transmit the generated third control signal to the fourth starter panel 700. The third control signal causes the first starter panel 700 to perform proportional control to maintain the predetermined temperature value at a predetermined reference temperature, (S330).

In this case, the amount of seawater supplied to the vacuum condenser can be adjusted, so that the power consumption of the seawater pump can be reduced.

4, when the integrated control unit 110 receives predetermined zone information required to be ventilated in the cargo loading zone in the ship through the ship automation system 300 (S410), the sixth variable frequency The drive control unit 920 generates a fourth control signal for causing the drive 920 to perform proportional control in which the temperature value measured in the region corresponding to the zone information is maintained at a preset reference temperature (S420) 6 to the starter panel 900 (S430).

In this case, it is preferable that the cargo loading zone in the ship is in a state in which a temperature sensor for measuring a zone corresponding to each zone information is measured.
