Description

The utility model relates to the field of security, in particular, to technical means providing quick and safe evacuation of people from buildings and structures during fires, earthquakes, floods and other emergency situations.

Known equipment and devices for fire alarm systems, containing light and sound annunciators installed in predetermined places, combined in an electric network, for example, with a DC power supply voltage of 12 V or 24 V. A list of such equipment is given in the product catalog manufactured by LLC "Electrical Engineering and Automation", 16 s, 3-7, the catalog is attached to the application materials, Appendix No. 1 (1).

At the same time, the fire alarm system created on the basis of the above-mentioned light annunciators with the indication of exits from the premises during evacuation is too static and has a drawback. For example, during a fire or natural disaster, a centralized lighting system from a public utility network is very often damaged. Often, only the light indicators of exits from the premises connected to the backup power source remain luminous.

However, in the absence of general lighting, it is very difficult for people to move along dark corridors, through thresholds, along stairs and ramps to emergency exits. In this case, often people fall, there is a stampede and panic.

There is also a system for emergency lighting of rooms, corridors, stairs, thresholds during fires and natural disasters, see the catalog of products of the company "White Light", 2006, 75 s, from 7-11, address

on the Internet: www.belysvet.ru (2).

On page 7 of this catalog is an emergency lighting scheme that provides emergency evacuation lighting and emergency lighting. At the same time, emergency evacuation lighting provides for three types of lighting: lighting of escape routes; lighting of hazardous work areas; and lighting that provides and prevents panic.

At the same time, this system is made of expensive lighting devices and components, and is also very energy-consuming and, on the whole, very cost-effective. With the destruction of buildings, this system is not tenacious. In this regard, the system has not found wide application.

The purpose of the proposed utility model is to develop and create a device - a comprehensive emergency notification system, lighting evacuation routes and fire-fighting equipment, as well as organizing and distributing people flows during evacuation.

The specified goal and the technical result are implemented as follows.

The proposed integrated system, like well-known systems, contains a power supply unit and light annunciators included in the fire alarm system.

But unlike the known above-mentioned analogues, the proposed system additionally contains light annunciators that are at least mounted on the ceiling of the room and emit light spots along the entire route of evacuation of people and fire extinguishing means, communications, alarms, electrical panels, etc., while in quality For the first time in practice, light sources in light annunciators have LEDs with miniature dimensions and, accordingly, minimal energy consumption compared to the used light sources.

At the same time, the entire integrated system is equipped with a backup power supply unit. In addition, for example, some light sirens installed on the most important facilities and evacuation routes are additionally equipped with a backup power source of the second level.

The proposed integrated system also additionally contains a device for generating sequential on-off light annunciators, forming as a result a kind of "running" light path with the possibility of direction and

distribution of people’s flows along this path to several nearest emergency exits from the premises during evacuation, while providing a dynamic and clear indication of the direction of movement along the entire evacuation path.

In addition to this, the system provides the simultaneous inclusion of sound (sirens) and voice annunciators during the evacuation of people from the premises with specific instructions for organizing the movement of people flows.

As an analogue of the proposed integrated system, you can take the emergency lighting system developed by the White Light enterprise according to the source of scientific and technical information (2)

The list of figures in the drawings.

Figure 1 shows a schematic diagram of the proposed integrated warning system for emergency situations, lighting evacuation routes and fire-fighting equipment, as well as the organization and distribution of human flows during evacuation.

Figure 2 shows a section of the floor of the room on which light spots are emitted by LEDs, mounted, for example, in narrow light panels with a length of, for example, three meters on the ceiling or on the wall.

Figure 3 shows a section of the corridor in the room, and on the floor there are two "running" light paths indicating the evacuation paths of two flows of people to two emergency exits.

The proposed integrated system contains the following devices, devices and parts.

The system is connected to an electrical network of alternating current voltage of 220 V through an electrical power source 1, which provides the entire system with direct current electricity of 12 V or 24 V. As a power source, the power supply unit of the control panel 3 can be used.

An electronic control unit 2 of the entire system is connected to the power supply 1, which is controlled by an alarm from the control panel 3, which can be connected to the central monitoring station 4.

An electronic control unit 2 is connected to a loop of light sirens 5 and 6, combined into a common electrical network, covering all light sirens and other devices installed along the entire evacuation route, for example, in shopping centers, exhibition

pavilions, sports facilities, in educational institutions with complex architecture and a scheme of escape routes.

Light annunciators 6 are equipped with a backup power source of the second level, for example, a miniature battery. Light sirens 5 and 6 are fortified with a predetermined interval in the light panels 7, made in the form of narrow plastic boxes with a length of, for example, three meters (figure 2). And the light panels 7 themselves are mounted on the ceiling or on the wall and, when joined together, form a light line along the entire escape route (in halls, corridors, on stairs, ramps), illuminating the floor, thresholds, steps, etc.).

Light indicators 8 of emergency exits, as well as sound (sirens) sirens 9 and voice sirens 10 can also be connected to the electronic control unit 2.

Light spots 11 (Fig. 3) emitted to the floor by light sirens 5 and 6, indicate the directions of people ’flows in the form of a“ running ”light path, which is created by the device for forming a“ running ”light track according to a given program by means of successive on-off switching of the light sirens, in emergency emergencies, when the entire integrated system operates in emergency operating mode.

In the same mode, sound (sirens) 9 and voice annunciators 10 installed in different rooms of the building are simultaneously turned on.

The proposed integrated warning system for emergencies, illumination of escape routes and fire-fighting equipment, as well as the organization and distribution of human flows during evacuation, operates as follows.

In the event of a fire or other emergency from the control panel 3, a command signal is sent to the electronic control unit 2, which turns on the entire system in Operation mode according to a given program, namely.

The entire loop of light sirens 5 and 6 is turned on, according to a given program, a “running” light track starts to function, sound 9 and speech 10 sirens are turned on. All of them indicate the direction of evacuation of people, illuminate all fire-fighting equipment, floors, thresholds, flights of stairs and routes to the nearest emergency exits.

In those places where a large number of people can accumulate, “running” light paths in combination with voice annunciators

indicate two or more directions of evacuation, thereby sharing and distributing the flows of people, preventing congestion, stampede and panic.

In the event of a failure of the 220 V common electrical network, the system switches to a backup battery power source, and the entire system continues to function and provides emergency illumination of emergency routes for up to 4 hours.

In the event of damage to the power supply line of the loop of light sirens 5 and 6, the lighting of the evacuation routes may turn off. But at this time, the “running” light track is no longer functioning, but a backup power supply of the second level is installed on each light siren 6. And light annunciators 6 are installed in this way along the entire evacuation route, so that all fire fighting equipment and equipment and evacuation routes are still partially lit.

And thanks to the uninterrupted lighting of corridors, walkways, as well as stairs, ramps, thresholds and other obstacles, people are prevented from falling, congestion and panic. At the same time, a visual dynamic indication of the direction of movement along the entire evacuation path is provided.

Thus, the proposed integrated system, even with the destruction of buildings, provides uninterrupted redundant illumination of rooms and evacuation routes for about 10 hours, which is quite enough for the complete evacuation of people from buildings during fires and natural disasters.

The proposed integrated system in comparison with known systems has a number of advantages, namely:

1. high efficiency in the evacuation and rescue of people in emergency situations due to the continuous illumination of all escape routes, including the dynamic functioning of all components of the system - a “moving” light path, the distribution and direction of people ’flows to emergency exits, sound and speech support for the evacuation order ;

2. long-term operation of the entire system in an autonomous mode from a backup power source due to the low power consumption of the components of the entire system;

3. low and affordable cost of equipment and components when creating the entire integrated system.
