Whether step 1, the 1st tunnel and the 2nd tunnel of fire detection system real-time detection parallel arrangement there is fire, it is assumed that
Detect the 1st tunnel and fire occurs, then used as accident tunnel, the 2nd tunnel is used as non-accident tunnel in the 1st tunnel；Determine accident tunnel
There is position in road fire；Position and the fire order of severity are occurred according to accident tunnel fire hazard, influence of fire region is determined；Fire
Influence of fire region is uploaded to PLC by detecting system immediately；
Step 2, PLC determines the corresponding local control cabinet in all horizontal holes in tunnel in influence of fire region, and to each
Individual local control cabinet is transmitted into the control instruction of pressure air blowing state；
In rapid 2, the local control cabinet that PLC belongs in influence of fire region to each is transmitted into pressure air blowing shape
After the control instruction of state, PLC is also transmitted into activating shape to other local control cabinets for being not belonging to influence of fire region
The control instruction of state；
For receiving the local control cabinet into state of activation control instruction, ultramagnifier is opened and closed by safety door in real time and is sentenced
Whether disconnected safety door between accident tunnel and the horizontal hole in corresponding tunnel is unlocked, if detect safety door be unlocked, this
Ground control cabinet enters into pressure air blowing working condition, then the pressure air blowing process for performing step 3.
Step 3, when local control cabinet receives control instruction, local control cabinet carries out pressure air blowing working condition,
It is specific to perform following steps：
Local control cabinet determines the rotation direction of bidirectional reversible formula blower fan 1, starts bidirectional reversible formula blower fan 1, and then will be non-
The fresh air in accident tunnel is persistently injected into tunnel Heng Dong, the horizontal hole internal pressure in tunnel is gradually increased；Meanwhile, local control cabinet leads to
Cross the internal pressure in the horizontal horizontal hole in hole press detection sensor real-time detection tunnel in tunnel, when the horizontal hole internal pressure in tunnel reach it is default
During supercharging value, air intake Electric air valve and air draft Electric air valve to the horizontal hole in tunnel coordinate control, make the horizontal hole inside pressure in tunnel
Power stabilization makes the horizontal hole internal pressure in tunnel more than accident tunnel internal pressure in default supercharging value, when accident tunnel and tunnel
When safety door between the horizontal hole in road is unlocked, the smog in accident tunnel is hindered to flow into tunnel Heng Dong.
Step 3 also includes：For the Electric air valve between connection accident tunnel and the horizontal hole in tunnel, bidirectional reversible formula blower fan leads to
Electric air valve earthward pressure air blowing is crossed, and then the safety door outside between the horizontal hole in accident tunnel and tunnel is formed air curtain, both
Make when the safety door between the horizontal hole in accident tunnel and tunnel is unlocked, air curtain can hinder smog to enter to tunnel from accident tunnel flow
Horizontal hole.
The reason for using step 2- steps 3 for：Due to after initial fire detection system determines influence of fire region, example
Such as, determine the region that influence of fire region is formed for P1 positions to P2 positions, then start all blower fans in P1 to P2 regions
Carry out pressure air blowing.However, because the fire intensity of a fire is constantly to change, therefore, when outside fire spreading to P1 to P2 regions
When, when personnel are evacuated by the tunnel Heng Dong outside P1 to P2 regions, however it remains tunnel has a large amount of smog in horizontal hole
Situation.Therefore, the method that triggering correspondence blower fan carries out pressure air blowing is started based on safety door present invention also offers above-mentioned, is passed through
The startup of safety door, determines that corresponding tunnel Heng Dong has personnel to pass through, therefore, the blower fan in the startup horizontal hole in tunnel carries out pressurization and send
Wind, this kind of mode flexibility is strong, and arrangement is simple easily to be realized.
The independently pressurized supply air system in the horizontal hole in tunnel and air supply method that the present invention is provided have advantages below：
(1) be embodied in the thinking of highway adjacent tunnel safety zone each other in ventilation smoke control device by the present invention, works as generation
During fire, realization takes wind in non-accident tunnel, so as to carry out pressure air blowing to tunnel Heng Dong, it is ensured that the horizontal hole in tunnel is to accident tunnel
Malleation, realize to the pressure air blowing in the horizontal hole in tunnel, prevent smog from entering tunnel Heng Dong from accident tunnel；Meanwhile, can also enter one
Step forms air curtain at safety door by air-valve, prevents to enter tunnel Heng Dong from accident tunnel, therefore, it is evacuating personnel and rescue
Safety guarantee is provided.The engineering reality of system combination vcehicular tunnel, simplifies pressure air blowing device, sets flexible, project scale
Small, engineering construction is strong.
(2) form of the present invention is simple, and easy to control, reliability is high, independent operating, it is adaptable to which passway for escaping quantity is more and pacifies
Full property requirement tunnel high, can effectively prevent smog from entering tunnel Heng Dong under fire working.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should
Depending on protection scope of the present invention.
