Method for controlling port loading and unloading apparatus and port loading and unloading apparatus

1. A method for controlling a port loading and unloading apparatus including

auxiliary equipment, which is equipment other than main equipment for performing main operations of the port loading and unloading apparatus,

the auxiliary equipment including

a main equipment cooling device for cooling the main equipment,

a loading and unloading lighting device for lighting a loading and unloading operation range,

a room cooling device for cooling a room of the port loading and unloading apparatus, and

a room lighting device for lighting the room,

the method comprising the step of

if an operating condition of the main equipment or a room condition satisfies a predetermined electric power reduction condition while the port loading and unloading apparatus is in operation, putting the auxiliary equipment that is keeping the operating condition of the main equipment or the room condition into a power saving mode in which the auxiliary equipment consumes less electric power than in a normal operation.

2. The method for controlling a port loading and unloading apparatus according to claim 1 , comprising at least one of:

a first step of,

if a temperature of the main equipment becomes equal to or less than a predetermined first main equipment temperature judgment value while the main equipment is in operation, judging that the electric power reduction condition is satisfied, and putting the main equipment cooling device into the power saving mode, and

if the temperature of the main equipment becomes equal to or less than a second main equipment temperature judgment value while the main equipment is out of operation, judging that the electric power reduction condition is satisfied, and putting the main equipment cooling device into the power saving mode; and

a second step of,

if brightness of the loading and unloading operation range becomes equal to or greater than a predetermined main equipment luminance judgment value while the main equipment is in operation, judging that the electric power reduction condition is satisfied, and putting the loading and unloading lighting device into the power saving mode, and

while the main equipment is out of operation, judging that the electric power reduction condition is satisfied, and putting the loading and unloading lighting device into the power saving mode.

3. The method for controlling a port loading and unloading apparatus according to claim 2 , further comprising:

an optimization step of optimizing an operation speed and an operation path of the main equipment using a genetic algorithm where an objective function is to at least reduce an amount of time which it takes to load or unload freight; and

a main equipment halting step of operating the main equipment at the operation speed optimized in the optimization step and via the operation path optimized in the optimization step, and halting the main equipment after the loading and unloading operation is completed.

4. The method for controlling a port loading and unloading apparatus according to claim 3 , further comprising

a third step of:

if a temperature of the room becomes equal to or less than a predetermined room temperature judgment value while the port loading and unloading apparatus is in operation, judging that the electric power reduction condition is satisfied, and putting the room cooling device into the power saving mode; and

if brightness of the room becomes equal to or greater than a predetermined room luminance judgment value, judging that the electric power reduction condition is satisfied, and putting the room lighting device into the power saving mode.

5. The method for controlling a port loading and unloading apparatus according to claim 2 , further comprising

a third step of:

if a temperature of the room becomes equal to or less than a predetermined room temperature judgment value while the port loading and unloading apparatus is in operation, judging that the electric power reduction condition is satisfied, and putting the room cooling device into the power saving mode; and

if brightness of the room becomes equal to or greater than a predetermined room luminance judgment value, judging that the electric power reduction condition is satisfied, and putting the room lighting device into the power saving mode.

6. The method for controlling a port loading and unloading apparatus according to claim 1 , further comprising

a third step of:

if a temperature of the room becomes equal to or less than a predetermined room temperature judgment value while the port loading and unloading apparatus is in operation, judging that the electric power reduction condition is satisfied, and putting the room cooling device into the power saving mode; and

if brightness of the room becomes equal to or greater than a predetermined room luminance judgment value, judging that the electric power reduction condition is satisfied, and putting the room lighting device into the power saving mode.

7. A port loading and unloading apparatus including

auxiliary equipment, which is equipment other than main equipment for performing main operations of the port loading and unloading apparatus,

the auxiliary equipment including

a main equipment cooling device for cooling the main equipment,

a loading and unloading lighting device for lighting a loading and unloading operation range,

a room cooling device for cooling a room of the port loading and unloading apparatus, and

a room lighting device for lighting the room,

the apparatus comprising

an auxiliary equipment controlling device for, if an operating condition of the main equipment or a room condition satisfies a predetermined electric power reduction condition while the port loading and unloading apparatus is in operation, putting the auxiliary equipment that is keeping the operating condition of the main equipment or the room condition into a power saving mode in which the auxiliary equipment consumes less electric power than in a normal operation.
