Description
Technical field
The present invention relates to a kind of fire control unit, particularly relate to a kind of fire control unit that can drive extinguishing device with timesharing.
Background technology
Along with development and the enhancing of fire-fighting consciousness in epoch, need to dispose in a lot of places extinguishing device, and in the biggest operative scenario, need to lay a lot of extinguishing devices, and these extinguishing devices are automatic fire extinguisher mostly.
The startup means of these extinguishing devices, such as dry powder extinguishing installation have fuse cord to start, nitrogen starts, electrically activates.
When the supersonic speed extinguishing device electrically activated is applied to large space fire extinguishing, existing method only uses the Traditional control pattern of aerosol fire-extinguishing, after extinguishing device simply series and parallel, synchronous averaging.
If guard space is very big, extinguishing device is thousands of, and the trigger starting these extinguishing devices also needs hundreds, so Financial cost is the highest, and fault rate is the highest.
And if the mode sprayed after extinguishing device connection in series-parallel, will be synchronized, then starting current would be the biggest, it is possible to cannot normally start extinguishing device, and if time substantial amounts of extinguishing device sprays, produced total kick is the biggest, has the biggest risk simultaneously.
With 2000m2Large space fire extinguishing scheme as a example by, if synchronous averaging, the most each dry powder extinguishing installation protection 10m2, its starting current is 800mA, 2000m2Large space be accomplished by 0.8A × (2000 ÷ 10)=160A starting current.If disposably starting all extinguishing devices, power supply equipment cannot bear.Large Copacity power-supply device expense is big, and cost is the highest.
Kick when each supersonic speed extinguishing device starts is 3000～5000N (newton), if implementing synchronous averaging, connected 4 extinguishing devices also have the biggest negative effect to building.
Summary of the invention
It is an object of the invention to the defect for existing fire extinguishing system, it is provided that a kind of fire control unit, it is achieved the zonal control of extinguishing device, thus reduce supply current, and recoil, failure rate is low can be reduced.
For achieving the above object, the invention provides a kind of fire control unit, described fire control unit
Including control module and control interface, described control interface includes:
Amplifying circuit, is connected with described control module, for receiving the control that described control module sends
Signal also amplifies；
Impulse circuit, is connected with described amplifying circuit, is used for producing pulse signal；
Output circuit, is connected with described amplifying circuit, for exporting the outside extinguishing device of the multichannel starting current signal enabling resolved into by control signal under the effect of described impulse circuit.
Described control interface also includes amplitude limiter circuit, is connected with described amplifying circuit.Described control interface is connected with fire-fighting power supply.Described control interface is multiple control interfaces, is connected with described control module respectively.
Therefore, fire control unit of the present invention, it is achieved the zonal control of extinguishing device, thus reduces supply current, and can reduce recoil, failure rate is low.

Detailed description of the invention
Below by drawings and Examples, technical scheme is described in further detail.
Because single extinguishing device is the least for large area fire effect, all extinguishing devices in protection zone the most disposably spray and waste very much.So a kind of combination spray pattern starting extinguishing device in units of unit of putting out a fire can be used the most economical, it is referred to as " cluster sprinkling ".
The present invention is a kind of fire control unit, and the extinguishing device controlled, by timesharing start-up mode, realizes " cluster sprinkling " fire extinguishing, to evade the double risks that starting current is too big, kick is the biggest when the synchronization of multiple extinguishing device is sprayed.
One fire extinguishing control signal can be transformed into sequence starting current signal by the present invention, exports with multichannel form timesharing, starts several extinguishing device, implements " cluster sprinkling " fire extinguishing.
Fig. 1 is the schematic diagram of fire control unit of the present invention, as it is shown in figure 1, the fire control unit of the present invention includes control module 2 and controls interface 1.Described control interface 1 is connected with described control module 2.Control interface 2 to be connected with fire extinguisher 3.
Fig. 2 is the schematic diagram controlling interface in fire control unit of the present invention, includes as in figure 2 it is shown, control interface: amplifying circuit 11, impulse circuit 12 and output circuit 13.Amplifying circuit 11 is connected with impulse circuit 12 and output circuit 13 respectively, and is connected with control module.
Control module 2 sends control signals to control interface 1, control signal amplification is sent to output circuit 13 by the amplifying circuit 11 controlling interface 1, and under the effect of impulse circuit 12, output circuit 13 exports the outside extinguishing device 3 of the multichannel starting current signal enabling resolved into by control signal.
Again as in figure 2 it is shown, control interface also include amplitude limiter circuit 14, it is connected with amplifying circuit 11.
Impulse circuit 12 speed can control in 1～10Hz.Setting cycle is 0.2s (second) left and right.Amplifying circuit 11 is then controlled signal magnification at high multiple.Because extinguishing device 3 starting current can not be the least, can not be the biggest.So controlling interface 1 to use amplitude limiter circuit 14, driving electric current to be limited in the most numerically, to guarantee the optimum start-up characteristic of extinguishing device 3, and then ensure that supersonic speed fire extinguishing system plays its extinguishing effect the most fully.
Fig. 3 is one of control interface figure schematic diagram in fire control unit of the present invention, is connected as it can be seen, control interface 1 with fire-fighting power supply 4, fire-fighting power supply 4 power to control interface 1.
Fig. 4 is in fire control unit of the present invention the two of control interface figure schematic diagram, as shown in the figure, if the number of the extinguishing device of fire extinguishing unit is more than the output channel number controlling interface 1, can also be used with multiple control interface 1 to carry out " cascade ", total energy meets the need of the extinguishing device startup in fire extinguishing unit.
So, any size space, all extinguishing device can be put out a fire easily control by fire control unit of the present invention.
In fire extinguishing procedure, the arbitrary instantaneous starting current of fire control unit of the present invention is up to about 800mA, starts power supply with a 2A and is sufficient to.
Arbitrary fire control unit instantaneous extinguishing device only one of which being activated in office, its kick is 3000～5000N (newton), and the negative effect to building is the least, will never destroy architecture noumenon.
This programme timesharing output enabling signal, two principal contradiction that when thoroughly solving synchronous averaging, starting current is big, kick is big.Thoroughly solve extinguishing device systematization, through engineering approaches, " bottleneck " problem of the marketization.
And the output of the end amplitude limit of fire control unit of the present invention, ensure the optimum start-up performance of extinguishing device.
It should be noted last that, above example is only in order to illustrate technical scheme and unrestricted, although the present invention being described in detail with reference to preferred embodiment, it will be understood by those within the art that, technical scheme can be modified or equivalent, without deviating from the spirit and scope of technical solution of the present invention.
