DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a lighting power supply system and method of a ship according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a block diagram showing a lighting power supply system for a ship according to a preferred embodiment of the present invention. FIG. 2 is a detailed view of the connection relation of the lighting switchboard 60 of FIG. 1, And a lighting control panel to be installed.

Referring to FIG. 1, a lighting power supply apparatus for a ship according to the present invention includes a power supply unit 10, a fire and gas sensing unit 20, a relay unit 30, a battery 40, a battery charging unit 50, (60), an illumination (70), and a control unit (80).

The power supply unit 10 is a main power supply unit for supplying power to the ship, and is generally provided with a 230 VAC voltage.

The fire and gas detection unit 20 includes a smoke detection sensor or a heat detection sensor and a gas detection sensor, and detects fire and gas leakage. And generates a fire / gas signal when smoke, fire, or gas is detected, and transmits the fire / gas signal to the control unit 80.

The relay unit 30 includes a photo cell and includes a plurality of switches for sensing light and turning on and off the lighting device 70. When a photo cell signal is generated when light of a predetermined intensity or more is detected, the switch is turned off. The control unit 80 controls the lighting switchboard 70 so that the lighting device 70 can be turned on or off according to the switching signal of the relay unit 30. [

When the fire / gas signal is detected, the battery 40 and the battery charging unit 50 are normally supplied with power from the power supply unit 10 and are charged with a constant voltage. The battery 40 is connected to the relay unit 30, and when a fire / gas signal is sensed, the relay 30 is operated to turn on the switch. The ship is provided with an uninterruptible power supply which operates in an emergency. However, if the switch connected to the lighting is not turned on even if the power is supplied, the lighting device will not be turned on, so a power source is required to operate the switch even when power is not supplied. The battery 40 performs this function. The uninterruptible power supply will be described later.

The lighting switchboard 60 is electrically connected to a plurality of lighting devices 70 installed in a ship, a drill ship, and an offshore facility to supply power to the lighting device. The lighting switchboard comprises a normal switchboard 62, an emergency switchboard 64, and a UPS switchboard 66. The emergency switchboard 62 is connected to an ordinary lighting device that is normally turned on and supplies power to the emergency switchboard 62. The emergency switchboard 64 is connected to an illumination device installed in a place where illumination is required even in an emergency, The UPS switchboard 66 supplies power to the lighting device 76 installed in the escape path where the crews can escape while the fire / gas signal is detected and the emergency lighting is all turned off. A power source of a constant voltage is supplied to the lighting switchboard 60. Power is supplied from the power source unit 10 to the normal distribution board 62 and the emergency distribution board 64 and power is supplied from the uninterruptible power supply unit to the UPS distribution board 66.

The control unit 80 controls the lighting switchboard 60 to turn on the battery 40 when the fire / gas signal is sensed and switch connected to the lighting device 76 installed in the emergency escape route . That is, when the fire / gas signal is detected and the power supplied to the normal distribution board 62 and the emergency distribution board 64 is shut off, the battery 40 is turned on to supply power to the relay unit 30, .

3, the battery 40, the battery charging unit 50, and the control unit 80 may be integrated into a remote control panel (Romote Control Panel), which is a panel for controlling various lights of the ship.

Let's take a closer look at the uninterruptible power supply, which we have briefly discussed above. Generally, uninterrupted power supply (UPS) is installed in ships, drilling facilities and offshore facilities, so it can provide power for a certain period of time even in an emergency. The uninterruptible power supply consists of a rectifier, a battery, and an inverter to continuously supply emergency power to critical systems even when the power is cut off due to power failure or power failure. The uninterruptible power supply unit converts AC power to DC in a normal state in which the used power is applied, and then charges the battery. When a power failure occurs, the DC power accumulated in the battery is converted into AC from the inverter and supplied as an emergency power do.

That is, even in an emergency, power is supplied to a device connected to the uninterruptible power supply for a predetermined period of time. However, in the case of a lighting device controlled by a remote control unit (RCU), there is a problem that the power supplied to the remote control panel is cut off and the lighting switch can not be turned on.

However, as described above, if the battery 40 is provided with a separate battery 40 for supplying power to the relay unit 30, the switching operation can be controlled through the power source of the battery 40 even if the power supplied to the remote control panel RCU is shut off .

3 shows the exterior of a remote control panel (RCU) 100 according to an embodiment of the present invention. Fig. 3 (a) shows the exterior of the panel 100, Fig. 3 (b) Fig.

3 (a), a plurality of control status lamps 110 and a plurality of control switches 120 are formed outside the remote control panel 100. Various warning lamps 130 are formed. As shown in the figure, a main power lamp 131, a photocell fail lamp 132 for notifying a failure or abnormality of the photocell, a power fail alarm lamp 133 A buzzer 134 for generating a warning sound when various problems occur, a buzzer stop button 135 for turning off a warning sound, and an auto / manual selection switch 136 can be formed.

3 (b), a battery 40 and a battery charging unit 50 are installed in the panel 100, and a relay unit 30 for controlling a plurality of control switches 120 is formed Can be confirmed.

4 is a flowchart illustrating a method of supplying illumination power to a ship according to a preferred embodiment of the present invention.

As shown in FIG. 4, it is determined whether or not the main power is first supplied (S100). If the power is not supplied, that is, when the power is off, the auxiliary battery is turned on (S110) (S112). If a fire / gas signal is detected, the UPS switch is turned on (S114). A UPS switch is a switch that controls the on and off of the lighting equipment connected to the UPS power supply. That is, even when the fire / gas signal is detected and the power is not supplied, the switch is turned on by the battery power, and the lighting device installed in the escape route connected to the uninterruptible power supply (UPS) is turned on. After the switch is turned on, the battery power is no longer needed, so the battery power is turned off for safety (S116)

If it is determined that the fire / gas signal is not detected, the warning lamp, that is, the power fail alarm 133 is turned on (S118). If there is no fire or gas leakage but the power is off, the warning light will be on. The warning lamp is terminated when the buzzer stop button S135 is pressed.

When the main power is supplied, it is checked whether the photocell power is turned on (S120). If the photocell power is turned off, the lighting switch is turned on (S122) and the photocell power is turned on (S124). The automatic mode can be operated by the user by pressing the button 146 of the remote control panel 100. When the illumination switch is turned on (S122), it is preferable that the photo cell fail lamp 132 is simultaneously turned on to confirm that the user does not operate the photocell.

In the manual mode (not shown), the lighting device of the area operated by the user is turned on. In the automatic mode, when the photocell signal is sensed and the photocell signal is sensed, that is, The lighting switch is automatically turned on (S128) and the lighting apparatus is turned on.

In FIG. 4, when the illumination switch is turned on, the illumination device is turned on automatically, so the on / off of the illumination device is not separately described.

 5 is a flowchart of a method of supplying illumination power to a ship according to another embodiment of the present invention.

Referring to FIG. 5, a fire / gas signal is first sensed (S200). If the fire / gas signal is not detected, the power is supplied to the normal state. If a fire / gas signal is detected, there is a possibility of a greater danger due to the fire of the ship, drill ship and offshore facilities. In order to prevent the explosion due to the singer retaining the power, the main power is turned off to shut off the power (S210). When the power supply is interrupted, the battery formed on the remote control panel 100 is turned on (S220) and the relay for on / off control of the lighting device installed in the escape route is operated. When the switch is turned on (S230) The installed lighting device is also turned on (S240).
