Description

A device for guiding and warning a blind and deaf person}

The present invention relates to an emergency alarm and guidance device for the visual and hearing impaired.

As shown in FIG. 1, generally, emergency lights are installed in a building to guide an emergency exit for people to escape in an emergency such as a fire.

Recently, the perception of the handicapped has been changed, and facilities for them, for example, a disabled lift in the subway, a disabled elevator in the building, etc. have been installed. However, since the emergency exit guide light disclosed in FIG. 1 is a guide device for a normal person, it is completely useless for the visually and hearing impaired, and there is a problem in that the disabled have no way to escape in case of an emergency.

An object of the present invention is to provide an emergency alert and guidance device for safe escape even in the event of an emergency even for persons with disabilities.

In addition, the emergency alarm and induction device 10 for the handicapped of the present invention is provided with a DC 12V emergency power capacitor 21 can operate even when a power failure occurs, fluorescent lamp 35, fluorescent lamp driving circuit 34 ), The second emergency power capacitor 32, the second emergency power capacitor 32 and the emergency induction lamp (30) consisting of the charging circuit 31 and the commercial power / emergency power switching circuit 33 is installed separately It is economical because there is no need to make space. In addition, there is an advantage that the simultaneous use of the power supply. Figure 6 is a perspective view showing a state in which the emergency warning and induction device 10 and the emergency induction lamp 30 for the handicapped in accordance with the present invention.

3 is a block diagram showing the structure of a wireless remote control of a disabled person using the emergency alert and induction device 10 for the disabled according to the present invention, as shown in Figure 3, the function button 50 for requesting a service for the disabled ), An encoder 51 for encoding and encoding an input signal of a function button, an RF transmitter for wirelessly transmitting the encoded signal through an antenna, and a DC 6V battery 53.

FIG. 5 is a circuit diagram illustrating a fire alarm detection circuit configuration using the fire hydrant fire alarm device 40. The diodes D1, D2, D3, and D4 for inputting the power of DC24V output from the fire hydrant fire alarm 40 regardless of polarity are shown in FIG. Condenser C1 which is continuously installed at the output terminal of the bridge circuit and the bridge circuit, which prevents oscillation of the constant voltage ICs (IC1: 78L12, IC2: 78L06) and the constant voltage ICs (IC1, IC2) for reducing the voltage to 12V and 6V, respectively. , C4, C6, and smoothing capacitors C2, C3, C5. The fire alarm detection circuit shown in FIG. 5 does not need a separate fire alarm detection sensor, and it is sufficient to operate simultaneously when the fire hydrant fire alarm device 40 is operated. That is, when the fire hydrant fire alarm device 40 is operated, it transmits to the handicapped emergency alert and guidance device 10 of the present invention as a radio signal.

Hereinafter, the operation of the emergency alert and guidance device 10 for the disabled according to the present invention described above.

As shown in FIG. 3, when a person with a disability presses a desired function button with his or her own remote control, the code signal generated by the encoder 51 is generated and propagated to the air through the RF transmitter 52.

As shown in Figure 4, when the alarm occurs in the fire hydrant alarm 40, the alarm bell installed in the fire hydrant alarm is ringing, at this time 24V voltage is generated in the alarm bell, this voltage is reduced to 6V by the circuit shown in Figure 5 to the transmitter Will be entered. When a DC 6V voltage is applied to the transmitter, a code signal set by the encoder 42 is generated and propagated to the air through the RF transmitter.

The signal propagated to the remote controller or the fire hydrant alarm in FIGS. 3 and 4 is demodulated in the RF receiver 12 through the antenna path of the handicapped emergency alert and induction device 10 of the present invention shown in FIG. Is entered. At this time, when the received code signal and the preset code match, the CPU analyzes whether the audio visual fire alarm or the door search signal is detected, and if the audio visual fire alarm signal is activated, operates the first voice synthesizer 15. The door is this way. You will hear a beep sound and a beep sound. If the signal to find the door to operate the second voice synthesis device 16 is a voice guidance "This is the first floor door".

The alarm emergency power continues to generate an alarm by connecting the first emergency power capacitor 21 which is automatically charged when the commercial power is cut off in case of fire. The emergency induction lamp 30 is continuously turned on in normal times, and when the commercial power is disconnected, the emergency induction lamp 30 is connected to the second emergency power capacitor 32 that is automatically charged until the commercial power is restored.

Therefore, according to the present invention as described above, there is an effect that can be used not only for the general public, but also the building position, such as the doors of the disabled and can be used as an alarm in an emergency.

Because it uses a wireless method, there is no need to wire with a fire alarm, which does not harm the construction cost and aesthetics. In addition, dozens of emergency induction lamps can be operated by one transmitter, which is effective for reducing the original cost.

The embodiments described so far are apparent to those skilled in the art that various modifications and variations are possible within the technical scope of the present invention, and such variations and modifications belong to the appended claims.
