Description

A Braille block system that provides safety and easy guidance when a fire occurs.

The present invention relates to a braille block system interlocking with a fire hydrant installed in a subway station, an underground walkway or an indoor building, and more particularly, The present invention relates to a braille block system capable of safely escaping toward a doorway by braille blocks installed on a floor without installing a separate wiring facility.

Generally, a fire hydrant is installed in an underground sidewalk, a subway station, or an indoor building so that people can easily prepare for fire when a fire occurs.

In the hydrants, hoses for supplying fire-fighting water are wound around the upper and lower doors, respectively, and an alarm button and an indicator lamp are formed on the upper door, And a starting relay is installed on the inner side of the vehicle with a siren for outputting an alarm sound. The starting relay is connected to a siren, an alarm button and an indicator lamp, and is connected to a fire hydrant and a wired line installed in a subway station, The fire alarms of any one of the fire hydrants are operated, all the fire hydrants installed in the respective areas simultaneously operate the alarm sound and the siren to inform the people of the occurrence of the fire.

However, when a fire occurs, the fire water is sprayed around, or the sprinkler installed in the room is running, and the water is in contact with electric appliances or electric wires, which leads to an electric shock. Especially, when there is a short circuit, a lot of new fire occurrence areas occur simultaneously There is a problem that it leads to a bigger fire.

Therefore, after a predetermined period of time after the fire occurs, the power is cut off by the administrator or the power is automatically shut off by the comprehensive control system.

However, when the external power is cut off, the operation of lamps or lamps installed in the subway history or underground sidewalks is stopped, so that it becomes difficult to find a way because the surroundings are darkly changed. In addition, It becomes difficult to find it, so it is difficult to evacuate, and if it is wrong, it leads to a big accident.

Therefore, by installing separate wiring facilities in the vicinity of the corridor or the stairway and thereby connecting the emergency light, the emergency light can be safely operated and informed of its position even if the lamp or the lamp of the hallway is turned off when a fire occurs.

However, when the smoke is filled up in the corridor when the fire occurs, the emergency light is blocked by the smoke having a higher quality than the light, and the light of the emergency light is not visible in the eyes of the pedestrian until it approaches,

Such an emergency light is installed only sparsely around the emergency exit, so there are many aspects that are incapable of guiding people toward a doorway in the event of a fire.

These emergency lights require extra wiring facilities, so they are rarely installed. Especially, more construction costs are required as additional wiring facilities are required.

FIG. 8 is a flowchart illustrating an operation procedure of a system according to an embodiment of the present invention.

When a fire occurs, the warning button 32 of the fire hydrant 30 installed in the vicinity is pressed by a witness, and in step S101,

The fire hydrant 30 is operated by the siren 33 and the indicator lamp 31 by the activation relay 34 connected to the alarm button to notify the persons located in the surrounding area of the occurrence of the fire.

At this time, the starting relay 34 of the fire hydrant 30 operates an indicator lamp and a siren of each fire hydrant arranged in the upper or lower layer or the surrounding area to notify everyone in the subway history, (S103)

At this time, the comprehensive control system 50 confirms the occurrence of a fire and then cuts off power in the building to prevent a larger fire or an electric shock accident, and then operates the sprinkler 40 to suppress the fire.

At this time, the fire detection can be confirmed by depressing the alarm button 32 of the fire hydrant. However, if the fire detection result of the spur ring closure 40 is confirmed, the integrated control system 50 cuts off the power inside the building The siren and the indicator may be operated through the activation relay of the fire hydrant 30 to notify people inside the building of the occurrence of the fire.

At this time, even if the integrated control system 50 cuts off the power and the passageway is darkened and the view of the pedestrian is not secured

In accordance with the "Act on the Promotion of the Convenience of Elderly Persons with Disabilities, etc." and "

And guides the passage through the braille block (2, 2a) provided on the bottom surface of the passage (1), the passage being connected to the doorway by a long light.

At this time, the braille block 2 may be guided by the main body 20a or 20b made of a phosphorescent material by automatically emitting light during the dark state. However, when the LED module built in the main body 20 emits light, You can do it.

That is, any one of the fire hydrants 30 includes a short range communication device 35 for transmitting an alarm signal to the inside of the fire brigade 30, 30) (S104, S105)

At this time, the main body 20 of the braille block 2 receives the alarm signal and is activated (S106). The control module drives the LED module and the sound output module based on the alarm signal to guide the fact of fire occurrence and the direction of movement (S107).

At this time, the control module of the braille block 2 controls the short-range communication module to transmit an alarm signal to the neighboring braille blocks forming the mesh network for activation.

Each of the braille blocks forming the mesh network is activated by receiving an alarm signal, and each of the control modules continuously performs an operation of driving the LED module and the audio output module,

Braille blocks installed in the subway history, underground walkway or inside the building guide the direction of movement by light or voice so that both the disabled, the deaf and the ordinary can easily escape safely to the entrance.

In this case, if some of the specific braille blocks forming the mesh network are broken due to an accident such as a fire or an electric shock, and the wireless connection is broken, each braille block generates a neighboring block The alarm signal is transmitted to the other braille block, and the alarm signal is activated to operate independently and stably.

In addition, the braille blocks arranged side by side in a state in which one or more rows are formed on the bottom surface include a solar cell or a piezoelectric element therein, and electric energy produced by the solar cell and the piezoelectric element is charged in the battery.

At this time, the electric energy produced through the solar cell or the piezoelectric element is raised by the regulator having the step-up circuit above the reference voltage of the battery,

The electric energy produced through the solar cell or the piezoelectric element is moved to the battery according to the voltage difference.

That is, even if the braille block is installed in the underground walkway, the subway history, or inside the building, even if the solar cell or the piezoelectric element produces a small amount of electric energy below the reference value, the battery is forcibly charged into the accumulator by the regulator or the booster circuit. Of the braille blocks are charging the required power

Therefore, even if the field of view is not ensured when the fire occurs, the braille blocks (2,2a) formed on the floor surface are connected to the doorway by light or sound to guide the moving direction, In addition, hearing disabled people and pedestrians around them can safely walk (escape). At this time, since the present invention is made of a high-strength compression material and forms a mesh network, damage caused by temperature difference or fire is minimized, and even if it is damaged, it can be safely escaped.
