Abstract

The intelligent evacuation system aims to develop a system of LED information panels that indicate the direction of the nearest exit, according to the information provided by a fire station on areas with fire danger. It is characterized by: # - Connected to the fire panel, making use of the information coming from it, to show the proper evacuation direction on each panel. # - Based on LED panels. The evacuation information will be displayed on installed LED panels and will be based on signals that indicate the safest evacuation direction to be taken from that sign. # - Fire resistant, the components and the communication elements between them are resistant in a certain way. degree to fire and high temperatures. # In case of fire it indicates the nearest emergency exits that are out of danger, avoiding routes affected by fire or blocked.

DESCRIPTION

Intelligent evacuation system.

State of the Technique

At the moment the signaling of the evacuation routes is carried out by means of photoluminescent signals, due to its low cost. Also its installation is usually normally incorrect, either due to inadequate dimensions at the distance of observation, due to its bad location or because the appropriate pictograms have not been selected for each case. Another factor to consider, is that no maintenance is performed on them, and these over time, lose their photoluminescent properties.

On the other hand, there are on the market evacuation signals with lighting, usually by means of LEDs, which are permanent and have sources of supply in case of lack of electricity supply.

As an alternative to these existing solutions in the market, the Intelligent Evacuation System arises, which is characterized, because it is a dynamic system, that is, they can change their illuminated pictograms depending on the real-time situation of the premises or building.

It has been proven by various studies that dynamic lighting is much more understandable for people who have to evacuate a building in case of an emergency (fire, earthquake, etc ...) and that evacuation times are greatly reduced with this type of signals.

On the other hand, there is no signal currently on the market that is dynamic and that depending on the situation and number of occupants of a building, is able to define the optimal and safest route for people to evacuate.

The Technical Building Code, in its DB-SI, requires, for sizing evacuation routes and their corresponding exit doors, corridors, stairs, etc ... to take into account the blocking hypothesis, which considers that any exit / emergency door can be blocked in case of fire.

The Intelligent Evacuation System is designed to take this hypothesis into account and be able to signal the alternative route in case an exit is blocked.

Description of the invention

The Intelligent Evacuation System consists mainly of the following elements:

- Dynamic evacuation signals

- Control unit

- Automatic fire detection system

- Wiring installation.

Next we will describe in detail each of the elements

- Senal dynamic evacuation.

It is the main element of the system and will serve for the signaling of the routes and evacuation elements, such as doors, corridors, stairs, etc ...

It will be composed of a monochrome LED panel (green color), a control unit of the LED matrix, which will be connected to the Control Unit, and a metal housing to house these elements.

Each of the signals will be programmed to indicate the appropriate evacuation pictogram, either by arrows (routes to exit doors, routes to emergency doors or through texts (exit, emergency exit, no exit, etc ...) The number of LEDs of each panel will be according to the resolution of the image we want to consider.

In its normal state, the pictogram assigned to that state will be on continuously.

The different pictograms of the Emergency Dynamic Signs will be those indicated in Standard UNE 23034: Fire safety. Security Signage: Evacuation Vlas.

The signals will have the dimensions indicated in the following table, depending on the pictogram, and for an observation distance of 10.0 meters.

 EXIT

 297x105 mm

 LOCATION SOCORRO output

 224x224 mm

 EMERGENCY EXIT

 297x148 mm

 DIRECTION to DISCOUNT output

 224x224 mm

 SOCORRO ADDRESS

 320x160 mm

- Control unit.

The control unit will be in charge of receiving the signals of the automatic fire detection system, in order to be able to determine, based on these signals, the optimal evacuation route, communicating with the different Emergency Dynamic Signs installed and acting on them to vary Your pictogram if necessary.

Normally this fire detection system is installed regularly in most buildings and premises, so it would only be necessary to receive the appropriate signals from it, from the different detection zones or from the zones

affected by a fire, so that the system, through its corresponding program, unique actions to be carried out at each of the Emergency Dynamic Signs that make up the system.

In case of fire and after the transmission of the fire signal from the fire station to the control unit, it will indicate the following actions to the Emergency Dynamic Signs:

- If the pictogram does not need to be modified, the Control Unit will order the Emergency Dynamic Signal to flash its LEDs, so that it is more visible to the occupants of the premises and can clearly determine which direction they should follow.

- If it is a "Exit" or "Emergency exit" pictogram, and it is locked, it will change its status to the "No Exit" pictogram and will be intermittent as well.

- If the Control Unit considers that the current direction of evacuation route indication is not adequate, it will indicate to the Emergency Dynamic Signal that the date of the evacuation route be changed, and it will be maintained with the LEDs flashing intermittently.

Once the Control Unit receives a signal from the fire station that the situation is normal, it will indicate all Dynamic Evacuation Signs to return to their normal state with continuous lighting.

- Automatic fire detection system.

Normally this system is mandatory by regulation in most buildings, depending on its use and surface.

In case the building / premises have this system, it should be designed distinguishing different detection zones, whether it is a conventional system or if it is analog, so that the Control Unit receives the necessary signals from each of the defined areas .

On the other hand, it will be important, for the proper functioning of the system, that each of the premises' doors, whether of usual exit or emergency, have a detector in its vicinity, so that the Control Unit can know when There is a blockage of one of the evacuation exits, and you can reprogram the Dynamic Evacuation Signs in the appropriate way.

- Wiring Installation.

It will be necessary to interconnect the Control Unit and the different Dynamic Evacuation Signals installed, so that they have power and communication to be able to change the configuration of the led panels.

This wiring must be of the AS + type, to guarantee the operation of the system even in case of fire.

Detailed exposition of an embodiment

An example of how to carry out the system would be its implementation in a place where there are means of fire detection such as push buttons (1), smoke detectors (2). The premises must have evacuation routes to the safe exits of the same, which will be marked by the dynamic evacuation signals (8), according to the scheme of emergency and evacuation plan permanently. In turn, the environment will be controlled by an image system through a Closed Circuit Video Surveillance System (6) and a People Counting System (7) that will be connected to the Analysis System (5). In the event that a fire occurs and any area is blocked or disabled, the detection systems (1) (2) through the fire panel (3) will notify the control unit (4) and on the other hand Through the Closed Circuit Video Surveillance Circuit (6) and the People Counting System (7), all necessary data will be taken that will issue warning signals to the Analysis System (5) that will analyze the data received, and will automatically send it to the Control Unit (4), which will change the Dynamic Evacuation Signals (8) indicating the safe evacuation routes of the occupants.
