Description
Technical field
The present invention relates to substation cable layer fire extinguishing fields, more particularly, to a kind of power transformation based on image fire detection device
It stands cable floor fire extinguishing system.
Background technology
With the high speed development of power industry, cable floor fire incident also happens occasionally.General cable floor is in relatively close
Narrow space is closed, when fire occurs, for flame along the rapid propagating combustion of cable, dense smoke, toxic gas, the high temperature of generation are high
Heat localization is in confined space, not only corrosion failure electrical equipment, but also threat human life safety, while repair is also relatively more tired
It is difficult.If cable floor occur fire after can automatic alarm fire extinguishing or as early as possible remind manually handled, can effectively reduce
Because event of fire is to the loss caused by electric system.
By retrieval, China Patent Publication No. is that CN206619839U discloses a kind of self-extinguishing type prepackage type power transformation
It stands, mainly by babinet, cable shaft, nitrogen storage tank, smoke alarm, applicator, self-closing vent window and ceiling exhaust fan group
At, ventilating duct can be automatically closed when fire behavior occurs, open simultaneously nitrogen valve injection nitrogen put out a fire, have insulating properties
Can good, corrosion-free, noresidue, the characteristics such as nontoxic, can be widely applied to the cities such as residential area, brightening illumination, agricultural facility
The unattended power supply place of the middle-size and small-size automation of utility grid, Rural Power Grid Construction.But although the utility model has used cigarette sense
Detector, but sensitivity or inadequate, there is the possibility of fire wrong report, and are unable to transmission of monitoring situation into monitoring
The heart, remote monitoring center can not check field condition and find out cause of fire.
Invention content
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide one kind being based on image fire
The substation cable layer fire extinguishing system of detector.
The purpose of the present invention can be achieved through the following technical solutions：
A kind of substation cable layer fire extinguishing system based on image fire detection device, including：Fire alarm control unit, fire extinguishing
Controller and extinguishing device, the system further include image fire detection device, and the image fire detection device is installed on cable floor
It is interior and connect fire alarm control unit, after the image fire detection device detects fire, trigger the fire alarm control
Device processed sends out sound and light alarm signal, starts Fire extinguisher, and the Fire extinguisher Time-delayed trigger extinguishing device is put out a fire.
Preferably, the extinguishing device is suspended type ultrafine dry powder extinguishing installation.
Preferably, the image fire detection device is by the detection to search coverage flame and smog, and locates simultaneously
Manage colour, black and white or the NIR images of search coverage, find and meet the big measure feature of fire, so carry out data fusion, decision and
Warning output.
Preferably, the Starting mode of the Fire extinguisher includes automated manner and manual mode.
Preferably, which further includes monitoring center, and the monitoring center is separately connected image fire detection device, fire
Alarm controller and extinguishing device, image fire detection device, fire alarm control unit and the extinguishing device are respectively to monitoring
Central transmission video stream signal, fire alarm signal and extinguishing action signal.
Preferably, the other equipment of the Fire extinguisher and substation cable layer links.
Preferably, in each image fire detection device monitoring area a suspended type ultrafine is filled every 4 meter amperes
Dry powder extinguishing installation, the suspended type ultrafine dry powder extinguishing installation radius of spray are 5 meters.
Compared with prior art, the present invention has the following advantages：
1, the ultrafine dry powder extinguishing installation based on image fire detection system uses colored, black and white and near-infrared three simultaneously
The different image of kind carries out analysis calculating, prevents fire from reporting by mistake using multi-party surface technology.
2, the sensitivity level of flame detecting being divided into Pyatyi, the sensitivity level of smoke detection is divided into nine grades, and
Using complex probe mode, keep system relatively reliable, flexible and efficient.Promote the false alarm prevention characteristic to non-fire source.It can also be right
Judgement is identified in more fire, while improving the detectivity to blocking fire, reduces fire miss probability.
3, incorporating ultrafine dry-chemical fire extinguishing equipment detects fire condition and exports fire alarm signal, beat when fire occurs
Ultra-fine dry powder fire-extinguishing apparatus is opened, corresponding region is carried out to spurt fire extinguishing, and personnel in station are reminded by sound-light alarm.For substation
The safe and stable operation of cable floor equipment provides safeguard, and tool has very great significance.
Description of the drawings
Fig. 1 is the fire extinguishing system structure principle chart of the present invention.
Specific implementation mode
The technical scheme in the embodiments of the invention will be clearly and completely described below, it is clear that described implementation
Example is a part of the embodiment of the present invention, rather than whole embodiments.Based on the embodiments of the present invention, ordinary skill
The every other embodiment that personnel are obtained without making creative work should all belong to the model that the present invention protects
It encloses.
As shown in Figure 1, a kind of substation cable layer fire extinguishing system based on image fire detection device, including：Fire alarm
Controller, Fire extinguisher and extinguishing device, the system further include image fire detection device, image fire detection device peace
Loaded in cable floor and connecting fire alarm control unit, after the image fire detection device detects fire, trigger described
Fire alarm control unit sends out sound and light alarm signal, starts Fire extinguisher, Fire extinguisher Time-delayed trigger fire extinguishing dress
It sets and puts out a fire.
The extinguishing device is suspended type ultrafine dry powder extinguishing installation.
The image fire detection device handles detecting area simultaneously by the detection to search coverage flame and smog
Colour/the black and white or NIR images in domain find the big measure feature for meeting fire, and then it is defeated to carry out data fusion, decision and alarm
Go out.
The Starting mode of the Fire extinguisher includes automated manner and manual mode, Fire extinguisher in the present invention
Starting mode uses manual mode.The system further includes monitoring center, and the monitoring center is separately connected image fire detection
Device, fire alarm control unit and extinguishing device, the image fire detection device, fire alarm control unit and extinguishing device difference
