Description

[0001] Emergency alarming apparatus [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a warning device, and more particularly, to a warning device capable of informing the outside of a fire or a power failure.

Fire detection alarm technology is well known. A well-known fire alarm system uses a switch that is in contact when the temperature is above a certain level. When a fire occurs and the switch is switched from OFF to ON, an electric current flows through a switch to a light emitting element and / or a load such as a speaker, and an alarm is generated.

However, since the switch for detecting a fire normally maintains a non-contact state, foreign matter such as dust accumulates in the contact space with time. This prevents the normal operation of the switch when a fire occurs. That is, even if the switch is switched from OFF to ON due to a fire, the foreign matter does not conduct and the fire alarm is not performed.

Korean Registered Utility Model No. 20-0278922 (issued on June 21, 2002)

An object of the present invention is to provide an emergency warning device for a disabled person and a non-disabled person that ensures normal operation of the switch.

BRIEF DESCRIPTION OF THE DRAWINGS The foregoing and further aspects of the present invention will become more apparent from the following detailed description of preferred embodiments with reference to the accompanying drawings. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a circuit diagram of an emergency warning device for a disabled person and a non-disabled person according to an embodiment. The transformer 110 receives AC 220V, which is a commercial power source, and converts it to AC 6V. The rectifying unit 110 rectifies the alternating current to direct current, and may be a bridge diode as shown in FIG. The bridge diode 110 rectifies AC 6V to DC 5V. The first sense switch 120 is connected to the output terminal of the bridge diode 110. The first sensing switch 120 operates to turn on the contact when the temperature is lower than the first reference value and to turn off the contact when the temperature is higher than the first reference value. That is, the contact-on state is maintained at normal times, and the contact-off state is switched when a fire occurs. If the temperature falls below the first reference value from the first reference value, it is of course switched from the contact off state to the contact on state. In one embodiment, the first sensing switch 120 is a bimetallic temperature switch. A plurality of first sensing switches 120 may be connected in series.

The inverter 130 operates by supplying power to the battery 170. When the low signal is input, the inverter 130 outputs a high signal. When a high signal is input, the inverter 130 outputs a low signal. In FIG. 1, when the DC voltage is supplied to the first pin through the first sensing switch 120 in the ON state, the output voltage of the second pin becomes 0 V (low signal), and the first sensing switch 120 is off and the DC voltage is not supplied to the first pin, the output voltage of the second pin becomes a positive voltage (high signal). At this time, the positive voltage may be 5V.

The relay 140 supplies battery power to the load 200 when an output voltage is supplied from the inverter 130, that is, when a high signal is input. In FIG. 1, when the relay 140 is not supplied with a voltage to the + terminal, the third terminal of the relay 140 is connected to the second terminal. That is, the third terminal of the relay 140 maintains a state of being connected to the second terminal during normal operation. In this state, when the output voltage from the inverter 130 is supplied to the + terminal, the connection between the third terminal and the second terminal is cut off, and an electrical connection is made between the third terminal and the first terminal. Accordingly, battery power supplied to the third terminal is output to the load 200 through the first terminal. The load 200 may include at least one of a visual notification means and an audible notification means. The visual notification means may be a light emitting diode (LEDs), and may include at least one of an illumination light 201 and a flashing light 202. The illuminating lamp 201 is used as an emergency light, and the flashing lamp 203 is used for emergency warning notifications for non-handicapped people as well as hearing-impaired persons. The audible notification means may be a speaker 203 and is used for emergency alert notifications for the visually impaired as well as the non-disabled.

The emergency alert device for the disabled and the non-emergency person may further include a first regulator 150. The first regulator 150 is a constant voltage regulator located at one end or the other end of the first sensing switch 120 and converting (dropping or boosting) the input voltage to a constant voltage. At this time, the input voltage is 6V, and the output voltage of the first regulator 150 may be 5V. The reason why the first regulator 150 is provided to convert the 6V voltage to the 5V voltage is to match the operating voltage of the inverter 130. [ In addition, the emergency alert device for the disabled and the non-emergency person may further include at least one first condenser 191 connected to an output terminal of the first regulator 150 to remove a surge voltage.

The emergency alert device for the disabled and the non-emergency person may further include a second sensing switch 160 and a battery 170. [ In one embodiment, the second sensing switch 160 is attached to one side of the battery 170 and is integral with the battery 170. The second sensing switch 160 operates to turn on the contact when the temperature is lower than the second reference value and to turn off the contact when the temperature exceeds the second reference value. That is, the contact-on state is normally maintained while the contact-off state is switched when the temperature is high. If the temperature falls below the second reference value from the second reference value, the contact-off state is switched to the contact-on state. In one embodiment, the second sensing switch 160 is a bimetallic temperature switch.

The battery 170 is charged by receiving the DC voltage rectified by the bridge diode 110 through the second sensing switch 160. Therefore, only when the battery temperature is lower than the second reference value, the second sensing switch 160 is turned on and the battery 170 is charged. When the battery temperature is higher than the second reference value, the second sensing switch 160 is turned off and is not charged. By such a second sensing switch 160, damage to the charging circuit as well as prevention of overcharging of the battery is prevented. The power supply voltage of the battery 170 is supplied to the inverter 130 and used as an operation power source. The power supply voltage of the battery 170 is supplied to the third terminal of the relay 140,

The emergency warning device for the disabled and the non-disabled person may further include a second regulator 180. The second regulator 180 is a constant voltage regulator located at one end or the other end of the second sensing switch 160 and converting (dropping or boosting) the input voltage to a constant voltage. In one embodiment, the input voltage is 6V and the output voltage of the second regulator 180 is 5V. The reason why the 6V voltage is converted to the 5V voltage by placing the second regulator 180 is to match the operating voltage of 5V of the circuit. The emergency alert device for the disabled and the non-emergency person may further include one or more second capacitors 192 connected between the bridge diode 110 and the second regulator 180 for removing the surge voltage. The diode 193 serves to prevent backflow.

Fig. 2 is an example of the use of an emergency warning device for persons with disabilities and non-disabled persons. As shown in FIG. 2, the main body 10 of the emergency warning device may be located at one side of the interior of the fluorescent lamp module 20. It should be noted that the first sensing switch 120 may be located outside the main body 10 but may be connected to the main body 10 to form the circuit diagram of FIG. As shown in FIG. 2, the first sensing switch 120 may be positioned on the left and right sides of the fluorescent lamp. That is, the first sensing switch 120 may be provided at different positions to detect a fire. 2, the main body 10 may be configured with a lighting lamp 201, a flasher 202, and a speaker 203. [
