Description

Emergency guidance device control method and system for tunnel {METHOD AND SYSTEM FOR CONTROLLING EMERGENCY GUIDANCE DEVICE IN TUNNEL}

The present disclosure relates to a method and system for controlling an emergency guidance device, and more particularly, to a method for controlling an emergency guidance device for a tunnel, which is continuously installed on a tunnel wall and guides pedestrians in an emergency, to turn on in a direction opposite to a smoke exhaust direction, and It's about the system.

Evacuation guidance lights are installed in tunnels in order to promptly and reliably guide people or vehicles to the tunnel exit or shelter in the event of an emergency such as an accident or fire in the tunnel.

Emergency guide light is a light that turns on when general lighting does not work in an emergency such as a power outage or fire, and must be installed in firefighting objects in accordance with the fire safety law or fire safety standards for guide lights and guide signs. Firefighting objects include, for example, living rooms, evacuation exit corridors, stairs, passages, and the like.

A light source is usually installed inside the emergency guide light, and a guide plate illuminated by the internal light source is installed on the front side. The light source is normally operated by commercial AC power, and is operated by DC power of the built-in battery when a power outage occurs in an emergency such as fire or disaster. The battery is normally charged by commercial AC power. In accordance with the Fire Protection Act, the emergency guide light maintains a continuous lighting state of more than a certain amount of light for 1 hour.

The basic cross-sectional shape of a tunnel can be classified into a horseshoe shape (horseshoe shape), a circular shape, and an oval shape, and most tunnels adopt an oval shape. A tunnel is a narrow and dark environment, and when a driver or pedestrian enters the tunnel, the pupil dilates and the field of view narrows, resulting in an optical illusion that looks farther than it actually is. When an accident occurs, it is not easy to deal with it in an enclosed space, and there is a risk of a secondary accident.

Conventional emergency guide lights have a problem in guiding without considering the direction of smoke exhaust when a fire occurs in a tunnel. When a fire occurs in a tunnel, a smoke exhaust system operates to discharge smoke. If a person evacuates in the tunnel in the same direction as the exhaust smoke, a problem of suffocation in the smoke may occur.

The present disclosure provides a method and system for controlling emergency guidance devices for tunnels to solve the above problems.

The present disclosure may be implemented in a variety of ways, including methods and systems.

The front light includes a left front light and a right front light.

According to an embodiment of the present disclosure, the front lamp control signal may correspond to a signal for controlling the left front lamp or the right front lamp to operate in a direction opposite to the smoke exhaust direction.

According to one embodiment of the present disclosure, the front light control signal may be determined according to a preset scenario.

According to one embodiment of the present disclosure, an emergency guidance device control system for a tunnel is provided. The system includes at least one emergency guidance device for tunnels having front lights including left front lights and right front lights and a central server communicating with the emergency guidance devices for tunnels, the central server is associated with a distribution direction from an external server. It may be configured to receive information and transmit a front light control signal to an emergency guidance device for a tunnel based on information related to a smoke direction.

According to an embodiment of the present disclosure, the front light control signal of the system may be a signal for controlling the left front light or the right front light to operate in a direction opposite to the smoke exhaust direction.

According to various embodiments of the present disclosure, in an emergency situation such as a fire in a tunnel, a front light of an emergency guidance device may be controlled and guided in a direction opposite to a smoke exhaust direction.

Claims (5)

A method for controlling an emergency guidance device for use in a tunnel in which a plurality of flue gas fans are installed by a central server communicating with a plurality of emergency guidance devices for tunnels, comprising:
Checking whether the power input unit of the plurality of emergency guidance devices for tunnels is normally operating;
Checking whether the front lights of the emergency guidance devices for a plurality of tunnels operate normally;
Checking whether secondary batteries of emergency guidance devices for a plurality of tunnels operate normally;
Receiving operation information of each exhaust fan from an external server; and
Based on the operation information, transmitting a front light control signal to a plurality of emergency guidance devices for tunnels
including,
The front lamp includes a left front lamp and a right front lamp,
The front lamp control signal is determined according to a preset scenario when the smoke exhaust directions of the respective exhaust fans are different,
Wherein the preset scenario determines the guidance direction of each of the plurality of emergency guidance devices for tunnels according to the exhaust direction of each exhaust fan.
delete delete An emergency guidance device control system for use in a tunnel in which a plurality of exhaust fans are installed,
At least one emergency guidance device for a tunnel having a front light including a left front light and a right front light; and
A central server communicating with the emergency guidance device for the tunnel
including,
The central server is configured to receive operation information of each exhaust fan from an external server and transmit a front lamp control signal based on the operation information to the emergency guidance device for the tunnel,
The front lamp control signal is determined according to a preset scenario when the smoke exhaust directions of the respective exhaust fans are different,
