Abstract
The invention relates to a fire extinguishing control device comprising a control module and a control interface. The control interface comprises: an amplifying circuit connected to the control module and used for receiving a control signal sent by the control module and amplifying the same; a pulse circuit connected to the amplifying circuit and used for generating a pulse signal; and an output circuit connected to the amplifying circuit and used for outputting a plurality of starting current signals decomposed from the control signal to start an external fire extinguishing device. The control interface further comprises an amplitude-limiting circuit which is connected with the amplifying circuit. Therefore, the fire extinguishing control device of the invention realizes zone control of the fire extinguishing device, thereby reducing power supply current, and is further capable of reducing recoil and low in fault rate.
Description
Technical field
The present invention relates to a kind of fire control unit, relate in particular to a kind of fire control unit that can timesharing drives extinguishing device.
Background technology
Along with the enhancing of development of times and fire-fighting consciousness, need settle extinguishing device in a lot of places, and, need lay a lot of extinguishing devices, and these extinguishing devices are automatic fire extinguisher mostly in the very big operative scenario.
These extinguishing devices, for example the startup means of dry powder extinguishing installation have fuse cord startup, nitrogen to start, electricity starts etc.
When the supersonic speed extinguishing device that electricity starts was applied to the large space fire extinguishing, existing method only was traditional control model of using aerosol fire-extinguishing, and extinguishing device simply after the series and parallel, is started synchronously.
If guard space is very big, extinguishing device is thousands of, and the starter that starts these extinguishing devices also needs hundreds of, so financial cost is very high, and fault rate is also high.
And if with the mode of spraying synchronously after the extinguishing device connection in series-parallel, then starting current is very big, might normally start extinguishing device, and if a large amount of extinguishing device when spraying simultaneously, the total kick that is produced is also very big, and very big risk is arranged.
With 2000m
2Large space fire extinguishing scheme be example, if start synchronously, each dry powder extinguishing installation protection 10m then
2, its starting current is 800mA, 2000m
2Large space just need 0.8A * (2000 ÷ 10)=160A starting current.If all extinguishing devices of disposable startup, power supply equipment can't bear.Big capacity power source equipment expense is big, and cost is too high.
Kick when each supersonic speed extinguishing device starts is 3000～5000N (newton), if implement to start synchronously, 4 extinguishing devices building is also had very big negative effect.
Summary of the invention
The objective of the invention is the defective at existing fire extinguishing system, a kind of fire control unit is provided, realize the subregion control of extinguishing device, reduce supply current thus, and can reduce recoil, fault rate is low.
For achieving the above object, the invention provides a kind of fire control unit, described fire control unit
Comprise control module and control interface, described control interface comprises:
Amplifying circuit is connected with described control module, is used to receive control signal and the amplification that described control module sends;
Impulse circuit is connected with described amplifying circuit, is used to produce pulse signal;
Output circuit is connected with described amplifying circuit, is used for the outside extinguishing device of multichannel starting current signal enabling that output is resolved into by control signal under the effect of described impulse circuit.
Described control interface also comprises amplitude limiter circuit, is connected with described amplifying circuit.Described control interface is connected with fire-fighting power supply.Described control interface is a plurality of control interfaces, is connected with described control module respectively.
Therefore, fire control unit of the present invention is realized the subregion control of extinguishing device, reduces supply current thus, and can reduce recoil, and fault rate is low.

The specific embodiment
Below by drawings and Examples, technical scheme of the present invention is described in further detail.
Because single extinguishing device is very little for the large tracts of land fire effect, the whole disposable sprinklings of all extinguishing devices in the protection zone are too waste again.So can adopt with the fire extinguishing unit is that unit a kind of combination spray pattern of starting extinguishing device is the most economical, is called " cluster sprinkling ".
The present invention is a kind of fire control unit, and the extinguishing device of being controlled is realized " cluster sprinkling " fire extinguishing by the timesharing start-up mode, the dual risk that the starting current when spraying synchronously to evade a plurality of extinguishing devices is too big, kick is too big.
The present invention can be transformed into sequence starting current signal with a fire extinguishing control signal, with multichannel form timesharing output, starts several extinguishing devices, implements " cluster sprinkling " fire extinguishing.
Fig. 1 is the schematic diagram of fire control unit of the present invention, and as shown in Figure 1, fire control unit of the present invention comprises control module 2 and control interface 1.Described control interface 1 is connected with described control module 2.Control interface 2 is connected with fire extinguisher 3.
Fig. 2 is the schematic diagram of control interface in the fire control unit of the present invention, and as shown in Figure 2, control interface comprises: amplifying circuit 11, impulse circuit 12 and output circuit 13.Amplifying circuit 11 is connected with output circuit 13 with impulse circuit 12 respectively, and is connected with control module.
Again as shown in Figure 2, control interface also comprises amplitude limiter circuit 14, is connected with amplifying circuit 11.
Fig. 3 is one of control interface circuit diagram schematic diagram in the fire control unit of the present invention, and as shown in the figure, control interface 1 is connected with fire-fighting power supply 4, gives control interface 1 power supply by fire-fighting power supply 4.
Fig. 4 is two of control interface circuit diagram schematic diagram in the fire control unit of the present invention, as shown in the figure, if the number of the extinguishing device of fire extinguishing unit is more than the output channel number of control interface 1, also available a plurality of control interface 1 carries out " cascade ", and total energy satisfies the need of the extinguishing device startup in the fire extinguishing unit.
So, any big or small space all can be by fire control unit of the present invention to the extinguishing device control of putting out a fire easily.
In fire extinguishing procedure, the arbitrary instantaneous starting current of fire control unit of the present invention mostly is about 800mA most, and it is just enough to start power supply with a 2A.
Arbitrary fire control unit in office one instantaneous extinguishing device that is activated has only one, and its kick is 3000～5000N (newton), and is very little to the negative effect of building, will never destroy architecture noumenon.
This programme timesharing output enabling signal, when thoroughly having solved synchronous startup, two principal contradictions that starting current is big, kick is big.Thoroughly solved " bottleneck " problem of extinguishing device systematization, through engineering approaches, the marketization.
And the output of the terminal amplitude limit of fire control unit of the present invention, ensured the optimum start-up performance of extinguishing device.
It should be noted last that, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, although the present invention is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement technical scheme of the present invention, and not break away from the spirit and scope of technical solution of the present invention.
