Abstract

The utility model discloses a distributed automatic fire alarm system. The system comprises a plurality of small subsystems in one-to-one correspondence with fireproof subareas, wherein the small subsystems are connected in parallel and all connected with a fire-fighting controller; each of the small subsystems includes sub control panels, and a smoke detector, a thermal detector, a fire-hydrant button, a hand-operated alarm button, a fire-fighting specific telephone, a fire-fighting broadcast, a fireproof valve and a non-fire-fighting power cut-off device which are connected with the sub control panels. According to the utility model, the conventional alarm system is divided into a plurality of small subsystems in one-to-one correspondence with the fireproof subareas, so that the control of the alarm system is distributed, the structure is simple and the reliability is high; and the distributed automatic fire alarm system takes full advantages that the distributed control is capable of completing preset functions in the condition that a fire-fighting control cabinet or a related communication device is failed.

Description

Distributed automatic fire alarm system

Technical field

The utility model belongs to the architectural electricity field, particularly relates to a kind of distributed automatic fire alarm system.

Background technology

Along with China's economic development, large-scale, ultra-large type commercial sport showground gets more and more, and fire compartment is numerous, and the scale of its automatic fire alarm system is also thereupon huge, and control requires complicated; Traditional emergency evacuation indication mechanism can be suitable in small building, but in large-scale and more complicated building, the path that it is unalterable has seemed unable to do what one wishes at evacuation efficiency and support personnel's secure context.

The utility model content

The utility model provides a kind of simple in structure, distributed automatic fire alarm system that reliability is high for solving the technical matters that exists in the known technology.

The technical scheme that the utility model is taked for the technical matters that exists in the solution known technology is: distributed automatic fire alarm system, comprise one to one small-sized subsystem of a plurality of and fire compartment, all described small-sized subsystems are in parallel, and all link to each other with fire-fighting control rack; Each described small-sized subsystem includes minute console panel and the coupled non-fire-fighting power supply device of smoke detector, heat detector, fire hydrant button, manual pull station, fire-fighting telephone for special use, fire broadcast, fire resisting damper and cut-out.

Console panel also was connected with LED intelligent evacuation Warning Mark and LED fire exit sign in described minute.

Console panel comprised computing unit in described minute, and described computing unit receives the data from described smoke detector, described heat detector and described manual pull station, calculated the best of fire generation subregion and evacuated the path; Described minute console panel evacuated the path according to the best and controlled described LED intelligent evacuation Warning Mark and the sign demonstration of described LED fire exit; The non-fire-fighting power supply device of fire broadcast, fire resisting damper and cut-out of described minute console panel control fire generation subregion and adjacent sectors thereof is finished corresponding action, and receives their feedback signal; All elevators of described minute console panel control fire generation subregion all fall in the first floor, and receive their feedback signal; Console panel fed back to described fire-fighting control rack with fire signal and control signal in described minute.

Advantage and the good effect that the utlity model has are: by traditional warning system being resolved into one to one small-sized subsystem of a plurality of and fire compartment, thereby make the distribution formula that is controlled to of warning system, simple in structure, reliability is high; Fully adopted distributed control can under the situation of rack or correlated communication equipment fault is controlled in fire-fighting, can finish the advantage of preset function; By LED intelligent evacuation Warning Mark and LED fire exit sign are joined in the distributed alarm system, and the best when being arranged on computing unit in minute console panel and calculating fire and occur is evacuated the path, controlling each Evacuation Indicatory Sign shows accordingly, improve evacuation efficiency, ensured to greatest extent personal security.

Description of drawings

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the structural representation of each small-sized subsystem of the utility model.

Embodiment

For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and cooperate accompanying drawing to be described in detail as follows:

See also Fig. 1 and Fig. 2, a kind of distributed automatic fire alarm system, suppose that building has the m layer on the ground, underground have a n layer, the corresponding small-sized subsystem of each fire compartment, each small-sized subsystem includes minute console panel and the coupled non-fire-fighting power supply device of smoke detector, heat detector, fire hydrant button, manual pull station, fire-fighting telephone for special use, fire broadcast, fire resisting damper and cut-out.Divide console panel also to be connected with LED intelligent evacuation Warning Mark and LED fire exit sign.Divide console panel to comprise computing unit, computing unit receives the data from smoke detector, heat detector and manual pull station, calculate the best of fire generation subregion and evacuate the path, minute console panel evacuates path control LED intelligent evacuation Warning Mark according to the best and LED fire exit sign shows; Divide the non-fire-fighting power supply device of fire broadcast, fire resisting damper and cut-out of console panel control fire generation subregion and adjacent sectors thereof to finish corresponding action, and receive their feedback signal; Divide all elevators of console panel control fire generation subregion all to fall in the first floor, and receive their feedback signal; Divide console panel that fire signal and control signal are fed back to fire-fighting control rack.

Principle of work of the present utility model:

When the building a certain fire compartment breaking out of fire the time, minute console panel to subsystem that should subregion starts fire broadcast, fire resisting damper and the non-fire-fighting power supply device of cut-out, the computing unit of this subregion receives the data from smoke detector, heat detector and manual pull station simultaneously, calculate the best path of evacuating, divide console panel to evacuate path control LED intelligent evacuation Warning Mark and the sign demonstration of LED fire exit according to the best, thus personnel in the building of evacuation fire zoning and adjacent sectors; Simultaneously, divide the firefighting fan of console panel control fire extinguishing pump and each layer to start; Fire-fighting control rack also can directly start the firefighting fan of fire extinguishing pump and each layer, and this point is identical with traditional fire-fighting system, does not do and gives unnecessary details.

Although the above is described preferred embodiment of the present utility model by reference to the accompanying drawings; but the utility model is not limited to above-mentioned embodiment; above-mentioned embodiment only is schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not breaking away from the scope situation that the utility model aim and claim protect, can also make a lot of forms, these all belong within the protection domain of the present utility model.
