Detailed description of the invention
Fig. 1 is that the present invention is based on the structural schematic diagrams of the fire detection of graphics process and fire-fighting link device.
Specific embodiment
The following further describes the present invention in detail with reference to the accompanying drawings and specific embodiments.
As shown in Figure 1, including: outside protection zone the present invention is based on the fire detection of graphics process and fire-fighting link device
Water tank 1, high-pressure water mist pump 5, image processing apparatus 18 and fire control console 19, and the protection zone spray in protection zone
Head, thermal imaging detector 14 and image detector 15.
Water tank 1, high-pressure water mist pump 5 and protection zone spray head pass sequentially through water pipe and connect into pipeline；The storage of 1 use of water tank is light
Water is used as extinguishing chemical, and water tank 1 is also connect with fire control console 19, and water tank 1 has liquid level emasuring device, and liquid level signal is reached
Fire control console 19, when liquid level is lower than warning value, fire control console 19 can issue alarm signal, prompt water shortage；High pressure
Water mist pump 5 makes the hydraulic pressure in pipeline reach certain pressure, meets end sprayer and form wanting for water mist for improving water flow pressure
It asks, in order to reduce the pipeline vibration that high-pressure water mist pumps 5 inlet and outlet, the inlet end and an outlet end difference of high-pressure water mist pump 5
Equipped with water outlet hose 4 and water outlet hose 6；Protection zone spray head includes protection zone upper layer spray head 16 and protection zone lower layer sprayer head
17, protection zone upper layer spray head 16 forms water mist, protects higher equipment or article for discharging extinguishing chemical；The spray of protection zone lower layer
First 17, for discharging extinguishing chemical, form water spray protection personnel and equipment.
Thermal imaging detector 14 and image detector 15 are connect with image processing apparatus 18, image processing apparatus 18 with disappear
Anti- console 19 connects, and fire control console 19 is also connect with high-pressure water mist pump 5.Thermal imaging detector 14 is for detecting in protection zone
Temperature change sends picture signal beyond the region of given threshold for temperature change；Image detector 15 is for detecting protection
Smoke signal in area, when detector judgement has smoke signal, transmission picture signal；Image processing apparatus 18 is for receiving thermal imaging
The figure signal that detector 14 and image detector 15 issue, and figure is identified and compared, when image meets fire item
When part, fire signal is issued；Fire control console 19 is used to receive the fire signal of image processing apparatus sending, prompts operator on duty
It controls high-pressure water mist pump startup or issues automatically activated signal to high-pressure water mist pump 5, so that persistently output high pressure water goes out
Fire.
The impurity in water blocks spray head in order to prevent, and the pipeline between high-pressure water mist pump 5 and protection zone spray head is equipped with filter
11。
Pipeline between water tank and high-pressure water mist pump is equipped with butterfly valve 2, and butterfly valve 2 is in normally open, when pipeline needs repairing
When, the connection of water tank 1 and pipeline can be cut off, facilitate the maintenance of pipeline.
Pipeline between high-pressure water mist pump 5 and filter 11 is equipped with shut-off valve 10 and pressure gauge 9, and shut-off valve 10 is for controlling pipe
Road on-off is in normally open, when system needs service or more exchange device, disconnects pipeline；Pressure gauge 9 is for measuring pump discharge
The pressure of water flow, can judge whether pump works normally according to pressure value；
The outlet end of water tank 1 and high-pressure water mist pump 5 is connected with relief valve 7 and safety valve 8 in turn, and relief valve 7 is for adjusting
The hydraulic pressure in pipeline is saved, when hydraulic pressure is more than the pressure that relief valve 7 is set, valve opening is prevented to reduce the pressure in pipeline
The only excessive damage for bringing attachment of pressure in pipeline；Safety valve 8 is for preventing the damage of relief valve 7 or the excessive pressure release of loine pressure
Valve 7 can not reduce pressure in time, damage to pipe-line system and accessory tapes.
Pipeline is also connected with the accumulator 12 for accumulating and discharging water, and accumulator 12 is used to reduce the wave of hydraulic pressure in pipeline
Dynamic, when hydraulic pressure is larger, accumulator 12 is under pressure, and accumulates hydraulic pressure；When hydraulic pressure is smaller, certain pressure is discharged, to stablize
Hydraulic pressure in pipeline.
Pipeline is also connected with pressure switch 13, and pressure switch 13 is connect with fire control console 19, the pipeline for will test
Hydraulic signal is transmitted to fire control console 19.Pressure switch 13 is for monitoring water flow pressure in pipeline, when having water to pass through in pipeline
When, pressure switch is opened, and issues pressure signal to fire control console 19, prompt system normally starts；
As a kind of preferred embodiment of the invention, extinguishing chemical release indicator light is also respectively connected in fire control console 19
20, manual automatic transfer switch 21 and emergency start button 22.Extinguishing chemical release indicator light 20 is used to that water to be prompted normally to discharge, when
Starter, release indicator light does not have bright, illustrates that there are failures in device；Manual automatic transfer switch 21 is for being arranged fire-fighting control
Platform processed automatically and manually mode；Emergency start button 22 is used for emergency start fire extinguishing system, when emergency occurs, need to start and go out
When fiery system, system can be directly initiated by lower button.
The present invention is based on the course of work of the fire detection of graphics process and fire-fighting link device is as follows:
When fire occurs in protection zone, smog can be generated or increase room temperature, thermal imaging detector 14 detects
After temperature change is larger in protection zone, picture signal is issued to image processing apparatus 18；Image detector 15 detects protection zone
After smog, picture signal is issued to image processing apparatus 18.After image processing apparatus 18 receives signal, to signal into
Row processing, if receiving only signal all the way, image processing apparatus 18 issues alarm signal to fire control console 19, and prompting may
Fire behavior occurs；If receiving two paths of signals, image processing apparatus 18 issues alarm signal and starting letter to fire control console 19
Number, united opening is spurted extinguishing chemical fire extinguishing by fire extinguishing system automatically.
When manual automatic transfer switch 21 is adjusted to manually, system will be unable to start automatically, need to be by operator on duty in fire-fighting control
Fire extinguishing system can just be started by pressing start button on platform 19 processed.
After fire control console 19 starts fire extinguishing system, starting high-pressure water mist first pumps 5, and the fresh water in water tank 1 is delivered to
Fire-fighting pipeline, while the water level in real-time monitoring water tank 1 can be to fire-fightings after high pressure water passes through pipeline cracking pressure switch 12
19 feedback signals are controlled, console receives pressure switch signal, opens extinguishing chemical release instruction lamp display system and works normally.
When pressing emergency start button 22, fire control console 19 can start high water mist pump 5 immediately, implement fire extinguishing.
