Description

It is taken refuge corridor Smoke prevention, protection and cold source system based on artificial intelligence underground

Technical field

It takes refuge corridor technical field the utility model relates to underground, it particularly relates to which a kind of be based on artificial intelligence underground It takes refuge corridor Smoke prevention, protection and cold source system.

Background technique

The Smoke prevention of corridor, smoke proof staircase and the room before the fire hydrant elevator of taking refuge in building at present relies primarily on forced draught blower pair Cup pressurizes, but lacks reasonable control measure when pressurization, is mainly exactly against fire bed (there are also each one layer up and down sometimes) All fire compartment cups pressurize.However, having many fire compartments since each layer of building divides, at present Pressure air blowing control no matter where take refuge where corridor whether subregion catches fire, whether corridor position of taking refuge has fire cigarette Gas is unlocked the forced draught blower of all subregions of fire bed, can not pressurize on demand.It frequently results in not catching fire in this way and subregion or not have The position pressurization of kindling is excessive, and frequent, pressure release is opened due to egress door in the position to catch fire in the subregion to catch fire and fire compartment Frequently, the pressure of cup but cannot keep, and fire disaster flame and flue gas is caused to invade.So need to develop accordingly according to fire behavior and The system that evacuation situation carries out on-demand pressure air blowing, efficiently utilizes fire-fighting blowing device existing capabilities.

Fire once occurs for underground commercial space, and the stream of people is required to evacuate to the ground by facilities such as corridors of taking refuge, evacuation The stream of people concentrates, and instantaneous flow of the people is big, and the door of smoke free lobby is opened frequently can not even close for a long time, in conventional pressure air blowing control The cup positive pressure that pressure air blowing is carried out under mode processed is difficult to maintain, and flue gas intrusion cup is even invaded by cup and taken refuge corridor Risk it is larger.Once take refuge corridor cup and corridor of taking refuge are invaded by high temperature of fire flue gas, closing underground population is mainly dredged Channel is dissipated, serious consequence is caused.It is therefore desirable to evacuate for take refuge corridor and its cup of underground commercial space in dense population When Smoke prevention and protection propose new scheme.

Large public building function is complicated, and the runing time of each functional areas is different.It, should by taking Tongren district Guizhou Province project as an example Project includes city level library, urban planning museum, archives local records shop, museum, science and technology center, Youth Activity Center, woman Female children's activity center, cultural art center, GuangDian Center etc., also dispersion are configured with tens of thousands of square metres of underground commerce room. After the facilities such as night city level library, urban planning museum, archives local records shop, museum close shop, matched building for commercial use, Retail shop needs to continue to do business.

China is promoting the regional cold supply system based on Regional Energy station at present.For example, Tong Ren District of Guizhou Province city relevant enterprise The multiple energy source stations of providing multiple forms of energy to complement each other of billions of member construction will be invested and carry out central cooling.Energy source station system of providing multiple forms of energy to complement each other refers to and can contain The input of various energy resources resource, and have the function of a variety of outputs and transport " Regional Energy internet " system of form.However, multipotency Complementary energy source station is as traditional area refrigeration system, when in face of runing time is inconsistent, demand is inconsistent builds with energy by owner When building, it is very low to will lead to system overall operation efficiency since rate of load condensate is lower.

Mating building for commercial use in large complex public building is especially divided into the mating quotient of independent shop one by one Industry room is not suitable for carrying out using energy source station cold source since runing time and use demand and building major function area are inconsistent Cooling supply.For example, most of venue all late 9:00 close when, energy source station be energy saving also stop cooling supply, but part retail shop Food and drink region still belong to and continue to do business；For another example, in the transition season in April, energy source station not yet cooling supply, but in the retail shop of underground by Lead to that room temperature is excessively high, needs cooling supply in advance greatly in inner heat source calorific value.So mating in large complex public building Building for commercial use needs to be arranged and the mutually independent cooling supply cold source of building major function area energy source station.

It is generally used as and is matched using split-type air conditioner or VRV air-conditioning system (Miniature air-cooling unit) in large complex public building Cover the cold source of the independent cold supply system of building for commercial use.However, for high standard public building, due to the aesthetics to outdoor ground It is very high with the comfort level requirement of outdoor garden landscape, to avoid noise and hot and cold air from polluting and avoiding seriously affecting beauty, The split-type air conditioner of underground commerce or the air-cooled outdoor unit of VRV air-conditioning system do not allow generally to place in outdoor ground.Some projects Using the method being placed on air-cooled outdoor unit in window well, but setting window well goes out ground and is also much limited.So often leading Cause mating business that independent cooling supply cold source can not be set.

Corridor of taking refuge refers to that the non-combustible component partition wall with fire endurance not less than 2h is separated to form, and is equipped with Smoke prevention, answers The facilities such as anxious illumination, for the current evacu-ation walk to outdoor outlet of personnel safety.It is since underground or first floor setting are straight-through Outdoor extra exit quantity and position it is subject to conditions without being able to satisfy technical norm for fire fighting requirement when (such as cause horizontal safety The special circumstances such as Travel distance is too long), just require a kind of evacu-ation walk of setting, usually without disaster when keep blank state.Its Evacuating width is calculated according to the sum of number of all fire compartments connected, and evacuating width is wider, and length is longer, is occupied The big quantity space of building.By taking the underground shopping of Guizhou as an example, about 13000 square metres of underground area of business, it is divided into 9 and prevents Fiery subregion, but the area in its corridor of taking refuge, 9 take refuge corridor smoke free lobby and its pressure air blowing ventilating shafts is up to 1590 square metres, Account for the 12.2% of area of business.Phase is made full use of on the basis of so how to evacuate when meeting fire safety rules, not influencing fire The space of pass is realized and is frequently necessary to solve the problems, such as in a kind of multiple functions in space (plain polder area) and architectural design.

With underground Rock And Soil contacts, underground that buried depth is deeper corridor of taking refuge it is generally cool in summer and warm in winter.Particularly, in karst region Area due to migrating etc. Rock And Soil thermal coefficient height and underground water, leads to that the exterior wall in corridor is taken refuge in underground and bottom plate etc. is gone along with sb. to guard him The heat exchange amount of structure and periphery Rock And Soil is higher than the heat exchange amount under other geological conditions such as silty clay, and underground is taken refuge the enclosing of corridor Protection structure is prone to moisture condensation mildew, and the take refuge air themperature in corridor of underground is easier access to karst region quality cool in summer and warm in winter Lower Rock And Soil.

The operation method of single area's fire working three is then to open electronic in single area's fire working one or single area's fire working Water valve, the low temperature chilled water in energy source station chilled water water supplying pipe, energy source station chilled water return pipe are opened to evacu-ation walk from being set to The deluge system of one top of smoke free lobby fire resistant doorsets sprays；When IRS image recognition sensor and artificial intelligence controller recognize Periphery without body surface excessive fire personnel when, at this time close dynamoelectric water valve stop water spray；

The operating condition that fire occurs for two neighboring subregion includes two-region fire working one, two-region fire working two and two-region fire Calamity operating condition three, in which:

The operation method of two-region fire working one is when having cigarette in the fire compartment one and fire compartment two of underground commerce When fog siren, temperature sensor, any one in IRS image recognition sensor issue fire alarm signal, pressurization is opened Before pressure fan and fire prevention pressure air blowing mouth one, fire prevention two pairs of pressure air blowing mouth take refuge corridor smoke free lobby one and corridor Smoke preventions of taking refuge Room two while pressure air blowing；When fire resistant doorsets are not turned on for a long time, and cup positive pressure value is increased more than 30Pa, electric fire-damper is opened Three-dimensional is taken refuge corridor pressure release, and pressure closes electric fire-damper three when reaching 30Pa or less；

Two-region fire working two is that only a distance evacuation mouth more nearby finds fire smoke gases or intensive in two subregions Stream of people's situation, operation method are when IRS image recognition sensor and artificial intelligence controller recognize smoke free lobby fire resistant doorsets There are fire behavior and flue gas in one periphery, and major pedestrian movement is close to smoke free lobby fire resistant doorsets one, and recognizes smoke free lobby fire resistant doorsets two weeks While there is no fire behavior and flue gas and when instantaneous nobody is ready to pass through smoke free lobby fire resistant doorsets two then instantaneously closes fire prevention pressure air blowing Mouthfuls two, and when the pressure release mode of smoke free lobby A being revised as cup A positive pressure value reaching 100Pa, it opens electric fire-damper three and lets out Pressure, booster fan instantaneously will be more than that one times of code requirement of air quantity is sent into and takes refuge corridor smoke free lobby one, make the cup instantaneous Reach good Smoke prevention identical with single area's fire working two and protection effect, and due to not having on two periphery of smoke free lobby fire resistant doorsets Fire behavior and flue gas and instantaneous nobody is ready to pass through smoke free lobby fire resistant doorsets two, then smoke free lobby fire resistant doorsets two remain turned-off, and keep away Difficult corridor smoke free lobby two is instantaneously still being able to maintain positive pressure；When IRS image recognition sensor and artificial intelligence controller recognize One periphery of smoke free lobby fire resistant doorsets is there is no flame or flue gas or there is no crowd is approaching or smoke free lobby fire resistant doorsets two weeks While start to occur flame or flue gas or have greater than 2 people close to when, then terminate two-region fire working two, switch to two-region fire working One；

Fire working three operation method in two-region is when IRS image recognition sensor and artificial intelligence controller identify evacuation Personnel have the case where body surface excessive fire, then open dynamoelectric water valve, in energy source station chilled water water supplying pipe, energy source station chilled water return pipe Low temperature chilled water is sprayed from the open type being opened to above the smoke free lobby fire resistant doorsets one or smoke free lobby fire resistant doorsets two of evacu-ation walk is set to Head sprays；When IRS image recognition sensor and artificial intelligence controller recognize periphery without body surface excessive fire personnel when, this When close dynamoelectric water valve stop water spray, save chilled water；

Wherein, it is fire later period such as single cup fire resistant doorsets or fire prevention that the fire later period, which invades the operation method of double cup operating conditions, When wall destruction is burnt, then the fire prevention pressure air blowing mouth of excessive fire cup should be closed immediately and opens the cup and is prevented towards corridor of taking refuge The corresponding dynamoelectric water valve of deluge system above vent side carries out water spray protection；Such as the smoke free lobby of two adjacent fire compartments By destroying, over-firing, losing fire-proof function and evacuation function, then the fire prevention pressure air blowings of two cups are all closed immediately Mouthful, and keep forced draught blower to open and open electric fire-damper three, it is blown by electric fire-damper three-dimensional cup of taking refuge, Mechanical makeup air is carried out to the smoke evacuation system in corridor of taking refuge, improves the reliability for corridor smoke evacuation system of taking refuge, and big in corridor low level Amount is sent into outdoor air, open all cups lead to the corresponding dynamoelectric water valve of deluge system taken refuge above the fire resistant doorsets side of corridor into Row water spray protection.

The utility model mainly has the advantage that compared with existing system

1, the on-demand pressure air blowing according to fire severity is realized based on image recognition and artificial intelligence technology.It is existing Technology is to have fire alarm then to carry out pressure air blowing to the smoke free lobby of the fire compartment or add to this layer of all cups in fire compartment Force feed wind, i.e., no matter fire behavior whether develop to the cup nearby, no matter fire smoke gases whether have invade the cup possibility, no matter Whether there are personnel to carry out pressure air blowing to the cup by the cup, but for fire behavior and the big cup increasing of pressure can not be evacuated Add air-supply, reinforce Smoke prevention.And the condition of a disaster difference that the utility model is faced according to each cup realizes on-demand pressure air blowing.It compares The existing technology pressurizeed respectively, be based on same blowing device, maximum probability occur single fire compartment fire occur when or two A immediate area fire severity not for the moment, it is big targetedly to greatly strengthen by fire threat, evacuation pressure The Smoke prevention ability of cup.And frequency conversion compared with the prior art or bypass pressure release mode will be extra equipped with a variety of new pressure release modes Air quantity be used, make full use of the draft capacity of fire-fighting equipment.And forced draught blower has in the fire later period to take refuge away The ability of corridor smoke evacuation system benefit wind.

Disaster-stricken individual is paid close attention to 2. realizing, according to carrying out on-demand pressure air blowing and protection the case where disaster-stricken people.The prior art Control means do not account for densely populated place degree between each fire compartment, the difference of the centrality of evacuation, but personnel concentrate and dredge Scattered fire resistant doorsets can be blocked by the stream of people, be opened for a long time and cause cup positive pressure insufficient, and flame and flue gas easily invade cup.This reality Pressurized supply air rate is rationally determined with the novel concentration that can evacuate personnel according to each fire compartment, is passed through in intensive people flow anti- Vent, fire resistant doorsets are prevented from flame and flue gas intrusion cup when can not close for a long time.

In addition, the prior art, which does not account for body surface excessive fire personnel, yet enters the timely protective treatment behind corridor and to keeping away of taking refuge The threat in difficult corridor.Since the high-temperature flue gas amount that the clothing of body surface excessive fire personnel, hair kindling initial stage generate is very limited, it is difficult to The 68 DEG C of closed nozzles rupture of corridor inner top of making to take refuge in time (is especially having mechanical smoke evacuation system and fire alarm chain-initiation In the case where work, a small amount of high-temperature flue gas of human body clothing kindling is easy to be drained by smoke evacuation system moment before heating nozzle), and Water spray limited strength after local closed nozzle rupture.The utility model closes on the fire resistant doorsets outlet in corridor in corridor cup of taking refuge Multiple encryption deluge systems are intensively arranged above immediate area, and (spacing of spray head is less than gate-width degree, goes out also much smaller than automatic water jetting Requirement of the fiery design specification to closed nozzle spacing, unit area water spray intensity is much larger than at the doorway that multiple deluge systems are formed Closed nozzle), it opens when excessive fire personnel enter and take refuge corridor or when needing to protect, and spray low temperature chilled water in refrigeration season, The flame of excessive fire personnel's body surface can be put out moment and cooling protection is carried out to personnel and fire resistant doorsets.

3, intelligence degree is high, and fire monitoring is accurate: the utility model is equipped with smoke alarm, temperature sensor, IRS figure Picture identification sensor carries out accurate measurements to fire, and identifies using IRS image recognition sensor and artificial intelligence controller Fire behavior development, and intelligent control is carried out to each equipment and actuator according to preset artificial intelligence control program.

4, plain polder area.Underground corridor of taking refuge has both piping lane function, saves space, and chilled water pipe is arranged in and is taken refuge away Corridor cup closes on above the fire resistant doorsets outlet immediate area in corridor, and corresponding setting motor-driven valve and deluge system can need based jet freezings Water, plain polder area realize multiple-protection-function.

5. solve the problems, such as that air cooling air conditioner outdoor unit (common distribution cold source) is nowhere arranged in underground commercial space, Using underground commercial space take refuge the pressure air blowing vertical shaft that corridor cup must be provided with space be arranged air-cooled unit outdoor unit, lead to It crosses with rain-proof and pod pressurized bulk blower cavity as floor register, avoids the prior art and Air cooler is separately provided The vertical window well of group outdoor unit and the problem that floor register is inconvenient and cost is high.

It 6, is that air-cooled unit outdoor unit is entered the wind using take refuge corridor air or the air draft of commercial air-conditioner area of low temperature in refrigeration season, it is energy saving Effect is good.Meanwhile air-cooled unit outdoor unit blower pair can be singly opened under the control of the controller according to the signal of Temperature Humidity Sensor Underground corridor of taking refuge carries out air draft, avoid underground from taking refuge building enclosure inner surface that corridor contacts with underground Rock And Soil condense and Mildew.

Fire working:

Generally there are multiple fire compartments in underground shopping.By taking certain project as an example, which is distributed in 5 In a single building, one underground commercial space of maximum is divided for 9 fire compartments.In order to reduce out adding for ground The aisle smoke free lobby of taking refuge of force feed ventilating shaft number, general every 2 adjacent fire compartments shares a pressure air blowing vertical shaft.

1) adjacent 2 subregions are without fire working:

When fire occurs for a certain subregion of underground commerce, but the smog alarm in fire compartment 1, fire compartment 2 25 When device 18, temperature sensor 19, IRS image recognition sensor 23 do not issue fire alarm signal, illustrate fire compartment 1, Fire does not occur in fire compartment 2 25.At this point, unlatching forced draught blower and 2 fire prevention pressure air blowing mouths do preventative pressurization. Under the operating condition, be in close state with lower component: electric fire-damper 1, electric fire-damper 2 10, electric fire-damper 3 11, Air-cooled unit outdoor unit 14, closed nozzle 27, dynamoelectric water valve 32.Under the operating condition, with lower component be in open, parameter acquisition or Operating status: fire prevention pressure air blowing mouth 1, fire prevention pressure air blowing mouth 2 13, pressure sensor 1, pressure sensor 2 16, Temperature Humidity Sensor 17, smoke alarm 18, temperature sensor 19, humidity sensor 20, VOC sensor 21, CO2 sensor 22, IRS image recognition sensor 23, deluge system 26, energy source station chilled water water supplying pipe 28, energy source station chilled water return pipe 29, Automatic water sprinkler systme water supplying pipe 30, forced draught blower 33, pressure sensor 3 34 and artificial intelligence controller 35.

2) operating condition (single area's fire working) that adjacent 2 subregions have 1 subregion that fire occurs:

The each fire compartment area of underground shopping object is 2000 ㎡ or so, for example planar dimension is 100m x 20m. Generally occur in some fire compartment when fire behavior occurs, in the fire compartment from point to surface, ascending gradually spread.It is theoretical On, it can just be spread to other fire compartments after fire burns the firewall and fire resistant doorsets that separate fire compartment.

Occurred according to fire and the positional distance that spreads take refuge corridor cup distance, instantaneously the number evacuated it is how many and at Function enters the factors such as the disaster-stricken situation (whether over-firing with it) of personnel for corridor cup of taking refuge, and single area's fire working can be divided into 3 seed types below (explanation of single area's fire working is for occurring fire in fire compartment 1).

Single area's fire working 1(fire behavior distance evacuates mouth farther out, the less normal evacuation operating condition of the stream of people): when underground commerce Smoke alarm 18, temperature sensor 19, IRS image recognition sensor 23 in fire compartment 1 and fire compartment 2 25 are appointed It anticipates one when issuing fire alarm signal, illustrates that fire occurs in fire compartment 1 or fire compartment 2 25.With fire compartment For fire occurs for alarm in one, at this point, the one 12 pairs of smoke free lobby pressurizations of forced draught blower 33 and fire prevention pressure air blowing mouth are opened, Fire prevention pressure air blowing mouth 2 13 remains turned-off.Since forced draught blower 33 and smoke free lobby pressure air blowing well 4 are anti-for corridor of taking refuge Cigarette cup 1 and corridor smoke free lobby 25 of taking refuge share, so the design maximum pressurized supply air rate of forced draught blower 33 is by disappearing 2 times of the single smoke free lobby air output of anti-proper calculation only open 1 fire prevention pressure air blowing mouth one when booster fan is opened When, the single maximum air supply rate for preventing fires pressure air blowing mouth one will be equivalent to 2 times of the air output by proper calculation, can evacuate When smoke free lobby fire resistant doorsets frequently open in the case where still ensure that and promoted the positive pressure value and door opening wind speed of smoke free lobby, rise To better Smoke prevention effect.Indoor positive pressure value is in 30Pa between 40Pa before pressure sensor 1 detects and takes refuge corridor When, it is difficult to avoid wind pressure that fire resistant doorsets is caused to be opened, fire prevention Smoke prevention of the pressure air blowing mouth 2 13 to fire compartment two is opened at this time Cup carries out preventative pressurization.When indoor positive pressure value is in 40Pa or more before pressure sensor 1 detects and takes refuge corridor, into One step opens electric fire-damper 2 10 to 2 25 pressure release of fire compartment, to promote the positive pressure value of fire compartment two, plays certain The effect for preventing fire smoke from spreading from fire compartment one to fire compartment two.It takes refuge away when pressure sensor 1 detects Indoor positive pressure value is in 45Pa or more before corridor, further opens electric fire-damper 3 11 and takes refuge pressure release in corridor 1 to underground, this When fire prevention pressure air blowing mouth 1, fire prevention pressure air blowing mouth 2 13, electric fire-damper 2 10, electric fire-damper 3 11 be to open State, to guarantee the not superpressure of corridor smoke free lobby 1 of taking refuge.Under the positive pressure value in corridor smoke free lobby 1 of taking refuge starts When drop, the reverse execution above process, i.e., when pressure is down to 45Pa or less, close electric fire-damper 3 11, pressure be down to 40Pa with When lower, electric fire-damper 2 10 is closed, when pressure is down to 30Pa or less, closes fire prevention pressure air blowing mouth 2 13.Remain hair The positive pressure value of the corridor smoke free lobby of taking refuge of the fire compartment one for feelings of lighting a fire does not waste sending for blower within zone of reasonableness The air quantity of wind energy power and pressure release carries out preventative air-supply, pressurization to adjacent fire compartment two and its cup and corridor of taking refuge.

Single area's fire working 2(dense population and the approaching operating condition of fire behavior): this operating condition is on the basis of " single area's fire working 1 " On, it is adjusted according to manner of execution and threshold values of the signal of IRS image recognition sensor to all parts, in reasonable range It is " single that interior whole air outputs with booster fan, which more preferably protect the operating condition for continuing through and avoiding fire to enter cup of crowd, Area's fire working 2 ".Underground shopping is crowded, and when fire behavior occurs, panic gregariousness evacuation easily occurs for crowd, is dredging At raw edge, evacuation fire resistant doorsets at and evacuation cup in occur it is crowded, front and back is pushed and shoved.Fire resistant doorsets increasing is pushed away although combining during more people are crowded The torque that people pushes is added, so that crowd is born higher cup positive pressure value (single to fan fire resistant doorsets such as when positive pressure value 100Pa The upper gravity for being evenly distributed with gross pressure and being approximately equivalent to 20Kg object, two adults can easily open), but continue the stream of people easily lead to it is anti- Vent can not close for a long time, and air quantity constantly leaks in cup, positive pressure is unable to maintain that, flue gas can not be stopped to invade cup.Even It will lead to and blocked at fire prevention pressure air blowing mouth by crowd, cause air-supply difficult.Fire prevention pressure air blowing mouth is located at by the utility model Higher than a high position for most people height, the problem of being blocked by crowd is avoided.Crowded limitation is evacuated solving fire resistant doorsets On the problem of can not closing for a long time, the utility model is achieved by the following scheme: in fire compartment 1 and fire compartment two Position that smoke free lobby fire resistant doorsets 1,26 top face of smoke free lobby fire resistant doorsets in 25 evacuate an endless flow of people (and smoke free lobby It is interior) it is respectively provided with IRS image recognition sensor 23, which is the prior art, can be acquired including fire smoke, flame and close Various images including collection crowd, and identified by artificial intelligence controller 35.(the fire compartment under single area's fire working For one), when IRS image recognition sensor 23 and artificial intelligence controller 35 recognize periphery and have fire behavior and flue gas and have big Amount the stream of people to smoke free lobby fire resistant doorsets 1 close to when (such as more than 20 people be close to 2 meters apart from when, design parameter can be according to reality Border situation is specifically set), then electric fire-damper 3 11, electric fire-damper 2 10 and fire prevention pressure air blowing mouth 2 13 are closed at once (and be revised as the manner of execution of this 3 components to open electric fire-damper 3 11 when cup A positive pressure value reaches 100Pa, and it is electronic Fire resisting damper 2 10 and fire prevention pressure air blowing mouth 2 13 still close), booster fan by be more than one times of code requirement air quantity be sent into keep away Difficult corridor smoke free lobby one.Such as fire resistant doorsets are opened by crowd at this time, and crowd persistently evacuates, although crowded lead to cup both ends Two fire resistant doorsets continue biparting while opening and can not close, but enough room temperature, cleaning forced air high speed from fire resistant doorsets Gush out, by flue gas flame shield except cup, and flue gas neighbouring on the door also functions to certain effect of dispersing, for evacuation people nearby Stream provides to breathe a large amount of high speed unheated airs with surface cooling.This operating condition copes with people with whole air outputs of booster fan Continuing through for group is approaching with fire behavior, and in the case where guaranteeing the reasonable situation of fire resistant doorsets unlatching moment, it is anti-to promote pressure air blowing at double Shield ability.

Under " single area's fire working 2 ", when IRS image recognition sensor 23 and artificial intelligence controller 35 recognize Smoke prevention When one 3 periphery of cup fire resistant doorsets is approaching there is no flame or flue gas or there is no crowd, to reduce cup positive pressure value and fire prevention Door unlatching moment avoids single old young, thin and weak or injured evacuation personnel from powerlessly opening fire resistant doorsets and evacuates, at this time by system shape State is restored (in practical projects can also by " single area's fire working 1 ", 30Pa be most in this case to " single area's fire working 1 " Low-pressure threshold values further decreases, to adapt to the evacuation demand of wound, weak personnel).

In the utility model implementation, under the various operating conditions of the utility model, as pressure threshold value is promoted to 100Pa Under " single area's fire working 2 ", the inadequate problem of fire resistant doorsets strength is opened if you need to further evade individual persons, it can also be in fire resistant doorsets Increase electronic auxiliary door opening device and push pressure sensor, when cup positive pressure is more than 30Pa and starting when someone pushes, assists It opens the door.

Single area's fire working 3(evacuation personnel's body surface excessive fire situation): on the basis of single area's fire working 1 or 2, work as IRS Image recognition sensor identifies that evacuation personnel have the case where body surface excessive fire (human body contour outline table in image at this time by the prior art There are the flame image or high-temperature infrared signal of bounce in face, can identify flame based on the prior art), then dynamoelectric water valve 32 is opened, Low temperature chilled water in energy source station chilled water water supplying pipe 28, energy source station chilled water return pipe 29 is (for cold season chilled water extinguishing effect It is better than room temperature fire water) from the ejection of deluge system 26 being opened to above the smoke free lobby fire resistant doorsets 1 of evacu-ation walk is set to, it sprays It over-fires personnel's body surface to the body surface come out from smoke free lobby, plays fire extinguishing, cool down, prevent high-temperature flue gas intrusion from taking refuge corridor and right The personnel evacuated in close to the fire resistant doorsets in aisle and aisle carry out the effect of cooling protection, while also effectively preventing kindling material It is brought into the safety that the shared life channel of each fire compartment is jeopardized in corridor of taking refuge.

Under " single area's fire working 3 ", when IRS image recognition sensor 23 and artificial intelligence controller 35 recognize periphery When without the personnel of body surface excessive fire, dynamoelectric water valve 32 is closed at this time and stops water spray, saves chilled water.Dynamoelectric water valve 32 can also be by Fire protection control room manual control remote opening as needed makes deluge system 26 spray water, before the rupture water spray of closed nozzle 27, Play the role of auxiliary fire extinguishing, Smoke prevention and protection.

Under above various single area fire workings, still for fire occurs in fire compartment 1, in addition to the above equipment Controlled to open or close, following equipment remains closed state: electric fire-damper 1, air-cooled unit outdoor unit 14.In the work Under condition, it is in unlatching, parameter acquisition or operating status: pressure sensor 1, pressure sensor 2 16, temperature always with lower component Humidity sensor 17, smoke alarm 18, temperature sensor 19, humidity sensor 20, VOC sensor 21, CO2 sensor 22, It is IRS image recognition sensor 23, deluge system 26, energy source station chilled water water supplying pipe 28, energy source station chilled water return pipe 29, automatic Water injection system water supplying pipe 30, pressure sensor 3 34 and artificial intelligence controller 35.

Under single area's fire working, when non-alarming fireproof point in the fire compartment 1 and fire compartment 2 25 of underground commerce Smoke alarm 18, temperature sensor 19, IRS image recognition sensor 23 in area any one issue fire alarm signal When, then system is switched into two-region fire working.

3) operating condition (two-region fire working) of fire occurs for adjacent 2 subregions:

Fire working 1(two subregion fire behavior distances in two-region evacuate mouths farther out, the less normal evacuation operating condition of the stream of people): it is local There are smoke alarm 18, temperature sensor 19, IRS image recognition in the fire compartment 1 and fire compartment 2 25 of lower business In sensor 23 any one issue fire alarm signal when, illustrate there is fire in fire compartment 1 and fire compartment 2 25 Calamity.At this point, opening forced draught blower 33 and 2 13 pairs of pressure air blowing mouth fire prevention pressure air blowing mouth 1, fire prevention corridor Smoke preventions of taking refuge Cup 1 and take refuge corridor smoke free lobby 25 while pressure air blowing.The work of the utility model and prior art pressure air blowing at this time Condition is identical.But when fire resistant doorsets for a long time be not turned on, cup positive pressure value increase more than 30Pa when, the pressure release mode of the utility model with The prior art is different (prior art is mainly that fan frequency conversion runs or use bypass pipe pressure release).The utility model is used to taking refuge The mode of corridor pressure release, i.e. unlatching electric fire-damper 3 11 to corridor pressure release of taking refuge, close electronic when reaching 30Pa or less by pressure Fire resisting damper 3 11.

Only have a distance evacuation mouth in two subregions of two-region fire working 2(and more nearby finds fire smoke gases or intensive people Stream situation): the probability very little of fire occurs simultaneously for multiple fire compartments, and general fire is originated then from a fire compartment Gradually spread to another fire compartment (the separation firewall fire endurance of fire compartment is 3 hours)." two-region fire working 2 " Explanation illustrate by for the distance evacuation mouth of fire compartment 1 more nearby finds fire smoke gases or intensive people flow.

" two-region fire working 2 " course of work is as follows: on the basis of " two-region fire working 1 ", when IRS image recognition passes Sensor 23 and artificial intelligence controller 35 recognize one 3 periphery of smoke free lobby fire resistant doorsets when having fire behavior and flue gas major pedestrian movement is to anti- Cigarette cup fire resistant doorsets 1 close to when (such as more than 20 people be close to 1 meter apart from when, design parameter can be specific according to the actual situation Setting), and recognize that 26 periphery of smoke free lobby fire resistant doorsets does not have fire behavior and flue gas and instantaneous nobody is ready to pass through smoke free lobby Fire prevention pressure air blowing mouth 2 13 is then instantaneously closed when fire resistant doorsets 26, and the pressure release mode of smoke free lobby A is being revised as cup A just When pressure value reaches 100Pa, 3 11 pressure release of electric fire-damper is opened.Booster fan instantaneously will be more than one times of code requirement of wind at this time Amount is sent into and takes refuge corridor smoke free lobby 1, make the cup instantaneously reach with " single area's fire working 2 " identical good Smoke prevention and Protection effect.Also, due to 26 periphery of smoke free lobby fire resistant doorsets there is no fire behavior and flue gas and instantaneous nobody be ready to pass through it is anti- Cigarette cup fire resistant doorsets 26, then smoke free lobby fire resistant doorsets 26 remain turned-off, and corridor smoke free lobby 25 of taking refuge instantaneously still is being able to maintain Positive pressure.

Under " two-region fire working 2 ", when IRS image recognition sensor 23 and artificial intelligence controller 35 recognize Smoke prevention When one 3 periphery of cup fire resistant doorsets is approaching there is no flame or flue gas or there is no crowd or smoke free lobby fire resistant doorsets 26 weeks While start flame or flue gas occur or have more people (> 2 people) close to when, then terminate " two-region fire working 2 ", switch to " two-region Fire working 1 ".

Two-region fire working 3(evacuates personnel's body surface and over-fires situation): the fire working 1 or on the basis of 2 in two-region works as IRS Image recognition sensor 23 and artificial intelligence controller 35 identify that evacuation personnel have the case where body surface excessive fire by the prior art, then Dynamoelectric water valve 32 is opened, the low temperature chilled water in energy source station chilled water water supplying pipe 28, energy source station chilled water return pipe 29 is from being set to The deluge system 26 for being opened to 26 top of smoke free lobby fire resistant doorsets 1 or smoke free lobby fire resistant doorsets of evacu-ation walk sprays, and is ejected into The body surface come out from smoke free lobby over-fires personnel's body surface, plays fire extinguishing, cools down, prevents high-temperature flue gas intrusion from taking refuge corridor and to tight The personnel evacuated in the fire resistant doorsets in adjacent aisle and aisle carry out the effect of cooling protection, while also effectively preventing kindling material quilt Bring the safety that the shared life channel of each fire compartment is jeopardized in corridor of taking refuge into.

Under " two-region fire working 3 ", when IRS image recognition sensor 23 and artificial intelligence controller 35 recognize periphery When without the personnel of body surface excessive fire, dynamoelectric water valve 32 is closed at this time and stops water spray, saves chilled water.Dynamoelectric water valve 32 can also be by Fire protection control room manual control remote opening as needed makes deluge system 26 spray water, before the rupture water spray of closed nozzle 27, Play the role of auxiliary fire extinguishing, Smoke prevention and protection.

4) the fire later period invades the operating condition (fire invades double cup operating conditions) of double cups:

Smoke free lobby is equipped with IRS image recognition sensor 23, and picture signal can be transferred to artificial intelligence controller 35 Identification cup fire condition (the existing warming of cup in practical projects, can also be used or cigarette sense controller carries out fire identification, But it is prone to false alarm situation: reports a small amount of flue gas intrusion cup for cup excessive fire by mistake).

Fire later period, such as single cup fire resistant doorsets or firewall destruction are burnt, and cup falls into enemy hands, over-fires, losing fire prevention function Function can and be evacuated, then should close the fire prevention pressure air blowing mouth of excessive fire cup immediately and open the cup and lead to corridor fire prevention of taking refuge The corresponding dynamoelectric water valve 32 of deluge system 26 above door side carries out water spray protection, reduces corresponding fire resistant doorsets surface temperature.It is another A cup for not destroying, over-firing carries out pressure air blowing and water spray protection (but at this time by single area's operating condition work by single area's fire working When excessive fire cup fire prevention pressure air blowing mouth and the corresponding electric fire-damper of cup that over-fires manner of execution be revised as it is normally closed, only Pressure release is carried out by electric fire-damper 3 11).

The fire later period, such as two adjacent fire compartments smoke free lobby by destroy, over-fire, lose fire-proof function and Function is evacuated, then all closes the fire prevention pressure air blowing mouth of two cups immediately, and keeps forced draught blower to open and opens electricity Dynamic fire resisting damper 3 11, is blown by electric fire-damper 3 11 to cup of taking refuge, and carries out machine to the smoke evacuation system in corridor of taking refuge Tool mends wind, improves the reliability for corridor smoke evacuation system of taking refuge.Also, in corridor, low level is largely sent into outdoor air, is conducive to mention Height takes refuge in corridor and the amount of fresh air of personnel respiratory region and to reduce air themperature.Meanwhile open all cups lead to take refuge away The corresponding dynamoelectric water valve 32 of deluge system 26 above corridor fire resistant doorsets side carries out water spray protection, reduces corresponding fire resistant doorsets surface temperature Degree, extends the fire resistance period of fire resistant doorsets.

The fusing of electric fire-damper 3 11 closing and chain stopping forced draught blower when fire further invades pressure air blowing well 33。

Due to the fire later period, the personnel into the scene of a fire are mainly fire suppression personnel, and fire suppression personnel need to be with evacuation people Member is back through taking refuge corridor and cup enters the scene of a fire and saves.When fighting personnel enter scene of a fire fighting by corridor of taking refuge at this time, Other than obtaining the information that fire protection control room understands, whether there can also be air-supply intuitive judgment adjacent according to electric fire-damper 3 11 Whether cup has destroyed, has over-fired, avoid opening by mistake open excessive fire cup cause fire fighter to be injured without transom fire resistant doorsets Fire spread is to corridor of taking refuge.

It such as takes refuge and fire occurs in corridor, then the deluge system 26 under dynamoelectric water valve 32 controls can be controlled in fire protection control room Lower unlatching cooperation closed nozzle 27 is put out a fire, is protected.

In the utility model implementation, need to illustrate there are also following problems:

Air-cooled unit outdoor unit 14 should use upper outlet air surrounding air inlet type.It is lower with periphery wall and air-cooled to seal off plate 36 Outdoor unit is fixed by bolts, is sealed using sealing joint strip, and removable seal isolation board 36 enters plate down space and carries out when needing Maintenance.

The image recognition sensor of the prior art can be used in IRS image recognition sensor 23, it is desirable that the sensor is being met an urgent need Under the low-light of illumination picture signal can be acquired for the image recognition of human body, crowd, flame and flue gas.For example, have it is infrared heat at IRS R60 night vision type thermal imagery sensor of picture etc..

Artificial intelligence controller 35 require at least have can run artificial intelligence image recognition program input/output module, Chipset and memory etc. also have to IRS image recognition sensor 23 in addition to having the function of General System intelligent controller The image model of acquisition is handled, using the function of issuing control signal after the judgement of conventional images recognizer.

The prior art can be used to write for artificial intelligence control program in artificial intelligence controller 35, wherein image recognition journey Image recognition algorithm in sequence can be used existing various intelligent algorithms, such as neural network, fuzzy set, and fractal theory is small Wave analysis and genetic algorithm etc..

The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model Protection scope within.
