Description

TECHNICAL FIELD [0001] The present invention relates to an emergency power supply and control apparatus having a fire alarm function,

More particularly, the present invention relates to an automatic emergency supply and control apparatus having a fire alarm function, and more particularly, to an automatic emergency supply and control apparatus having a fire alarm function, To an automatic emergency supply and control device having a fire alarm function capable of promptly and safely evacuating by warning a fire situation where there is no power outage.

Generally, a sensor or the like is installed in an elevator hall or a stair of an apartment or a building. The sensor or the like is turned on when a person's approach is detected by the human body sensor, and is turned off after a predetermined time. On the other hand, apart from the sensor and the like, a emergency light is provided for illuminating the passage or guiding the evacuation route by lighting during a power failure. Generally, the emergency light is automatically turned on when the power is constantly switched to the emergency power source, and the light continues to be on until the power is restored at all times.

Fig. 1 shows an example of a conventional emergency light including a sensor and an emergency light set in a single luminaire. Two regular power supply lines 12 and two emergency power supply lines 14 are led into the lamp 10. The constant power line 12 is connected to the sensor 24 via the human body sensor 22 and the emergency power line 14 is connected directly to the emergency light 34. Then, the electric wire branched from the always-on power supply line 12 is connected to the emergency light 34 via the emergency operation switch 32. Although not shown, the emergency priority power source is turned off by the normal priority drive circuit when the constant power source is alive, and the emergency power source is switched to the emergency power source to supply the emergency power source to the lamp 10 when the power source is always turned off by the power failure.

Such emergency light including a sensor or the like functions normally as a sensor which is supplied with power at all times and lights up the sensor lamp 24 when the human body approaches. At this time, the emergency light 34 is turned on by operating the emergency light operation switch 32 manually. When a power failure occurs due to a fire or other situation, the emergency light source 34 is switched from the constant power source to the emergency power source and the emergency light 34 is automatically turned on by the emergency power source.

However, there are some problems with the above-described emergency light including the sensor and the like. First, since the emergency light is turned on only in an emergency, the provision of the sensor and the emergency light as separate lamps causes a waste of material, and there is a problem in that the wiring is complicated because four wires are drawn in one lamp.

Another problem is that when a fire occurs in the live state of the constant power source, the emergency power source is not drawn and the emergency light 34 must be turned on by the manual operation switch 32. [ However, since smoke is usually generated in association with a fire, it is difficult to find the manual operation switch 32 by the smoke, and the emergency light 34 can not be lighted on time, resulting in a large loss of life.

Korean Patent Laid-Open Publication No. 10-2013-0009362 discloses an emergency light system that is automatically turned on when a power failure or a sensor is detected and is equipped with a buzzer. Reference is made to the prior art document, which refers to a technique of effectively warning an emergency situation to people in a building by lighting an emergency light when a power failure or a fire is detected. This allows the stomachs to recognize and safely evacuate in the event of an emergency.

However, in the preceding literature, a buzzer sounds when a power failure occurs even though no fire has occurred. This causes people in the building to mistake themselves for an emergency and hasten evacuation, causing confusion and unnecessary downtime.

In addition, when a fire occurs in a state where the power is always on, the emergency light is turned on by the manual operation switch, so that the emergency light is not turned on and the buzzer does not operate. Therefore, it is necessary to notify the stomach precisely when a fire occurs in the state of live power supply at all times.

Hereinafter, description will be made for each situation with reference to FIG.

i) When the commercial power is applied,

2, since the second relay switch 237 is open and the first relay switch 232 is open according to the energization of the second relay 550, The breaker 231 is broken and the emergency power supply is not supplied.

Since the third relay switch 241, the fourth relay switch 242, and the 5-1 relay switch 243 are in the normally closed state, only the constant light is turned on.

ii) When a fire occurs while commercial power is applied

When a fire occurs, the fire detection switch 218 is closed and the fire power supply 217 is applied to the first relay 219. The emergency power supply is applied to the wiring breaker 231 to excite the first power supply switch 231 according to the energization of the first relay 219, And the first and second wiring cut-off switches 233 and 234 operate to supply the power supply line and the ground line of the emergency power supply to the load side.

When the emergency power is supplied to the load side, 24 volt and 5 volt power supply voltages are output from the emergency power supply (see Fig. 3), and when the 6th relay 429 is excited by the 24 volt emergency voltage, 6-2 relay switches 245 and 246 are closed, and the alarm unit 251, the emergency light 252, and the constant light 253 are turned on (see FIG. 2).

Since the first photocoupler 410 of FIG. 4 maintains the turned-on state when the constant power source is being applied, the control signal generating IC 420 does not output the third and fourth relay control signals, Relays 426, 427 and 428 are not energized.

If the 1-2 relay switch 215 is closed according to the energization of the first relay 219, the emergency power source is superposed on the first relay 219 until the reset switch 216 is operated, do.

iii) During power failure

Since the second relay switch 237 is short-circuited according to the element of the second relay 550 during the power failure, the wiring breaker 231 is excited to supply the emergency power.

When the emergency power is supplied to the load side, 24 volt and 5 volt power supply voltages are output from the emergency power supply (see Fig. 3), and when the 6th relay 429 is excited by the 24 volt emergency voltage, 6-2 Relay switches 245 and 246 are closed (see Fig. 2).

The first photocoupler 410 of FIG. 4 is turned off, and the control signal generating IC 420 outputs the third and fourth relay control signals, 5 relay 426, 427, and 428 are energized, and the alarm unit 251 does not operate because the 5-2 relay switch 244 is opened.

The invention described above is susceptible to various modifications within the scope not impairing the basic idea. In other words, all of the above embodiments should be interpreted by way of example and not by way of limitation. Therefore, the scope of protection of the present invention should be determined in accordance with the appended claims rather than the above-described embodiments, and should be construed as falling within the scope of the present invention when the constituent elements defined in the appended claims are replaced by equivalents.
