Description
Technical field
The present invention relates to the technical field of safety protection of passenger room of railway vehicle, especially a kind of distributed active suppression skill
Art.
Background technique
Traditional passenger room of railway vehicle fire extinguishing uses induction type pyralarm, when alarm detects sufficient concentrations of cigarette
Pyrotechnics alarm is triggered after fire, is put out a fire using vehicle-mounted fire extinguisher to fire source by crew member or passenger, whole process is not only
Valuable attack time is consumed, while scene of fire is trained due to personnel without unified command and without profession fire extinguishing, very
Difficulty guarantees to put out a fire or control the intensity of a fire rapidly, can not control the smog spread in train, while putting out a fire
Extinguishing chemical used in journey can cause secondary injury to passenger and train.
Summary of the invention
The object of the present invention is to provide a kind of rail vehicle distribution active suppression schemes, can be early stage fire occurs
Early warning after fire behavior is detected, the high-pressure water mist spray head that conflagration area occurs for automatic starting puts out a fire to kindling point, Neng Gouyou
The safety for ensuring passenger and vehicle when fire occurs of effect.
In order to achieve the above objectives, the present invention provides a kind of rail vehicle distribution active suppression schemes, it is characterised in that: packet
Include fire extinguishing system host, radiant type pyrotechnics detection probe, spray head, water tank, nitrogen cylinder, radiant type pyrotechnics detection probe and spray head
Quantity it is identical, and be arranged in guest room the same area, correspond, radiant type pyrotechnics detection probe is by cable and fire extinguishing
Host of uniting connects, and spray head is connect by the water tank and nitrogen cylinder installed under steel pipeline and solenoid valve and vehicle, and solenoid valve is simultaneously
It is connect again with fire extinguishing system host；Fire extinguishing system host is connect with train network system, for transmitting the indoor temperature field of visitor
Screen display is shown to train network system and in driver, fire extinguishing system host passes through solenoid valve control water tank and nitrogen cylinder,
Water and nitrogen are filled with steel pipe, fire extinguishing system host sprays heavy pressure fine spray to fire position by starting corresponding spray head, complete
At active suppression.
A kind of control method of rail vehicle distribution active suppression schemes, it is characterised in that include the following steps:
Temperature information is received, the threshold value of current temperature information and setting is compared, if it exceeds the threshold, alert；
Start solenoid valve, nitrogen and water enter steel pipe, forms heavy pressure fine spray in steel pipe；
The spray head for starting the pyrotechnics probe area of alarm sprays heavy pressure fine spray.
The temperature information is more than threshold value and for 10 seconds, while having 2 adjacent radiant type pyrotechnics detection probes same
When detecting the information, it is determined that fire occurs really, otherwise it is assumed that wrong report.
The present invention is separately connected radiant type pyrotechnics detection probe, solenoid valve and spray head by fire extinguishing system host, passes through
Principle of infrared radiation obtains the indoor thermo parameters method of visitor, for perceiving the indoor information on fire of visitor, and thermo parameters method is led to
Data transmission fiber real-time delivery is crossed to fire extinguishing system host, fire extinguishing system host receives temperature field information, and passes the information on
Shown to train network system and on driving position, when fire behavior occurs, fire extinguishing system host according to preset alarm threshold value simultaneously
Judge whether fire behavior occurs really in conjunction with decision logic, after fire behavior occurs for confirmation, system host starts solenoid valve, by water tank
Nitrogen in interior water and nitrogen cylinder mixes and is filled with steel pipeline, and fire extinguishing system host-initiated detects the radiant type cigarette of fire behavior
Heavy pressure fine spray is injected in fire behavior region with the spray head of group by fire detection.The present invention can realize essence early stage fire behavior occurs
True active suppression, while a large amount of smog that can adsorb fire when generates, extinguishing chemical is water, not to the indoor passenger of visitor and vehicle
It will cause secondary injury.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention；
Fig. 2 is the flow chart of fire extinguishing system control of the present invention.
Specific embodiment
Referring to Fig.1,5 radiant type pyrotechnics detection probes 1 are uniformly installed on roof center line in the guest room of vehicle, and
The roof center line for being no more than 10 centimeters apart from each pyrotechnics probe distance installs 1 fine mist spray head 2, and by this 2 groups
Part is defined as one group, and each car amounts to 5 groups of installation；Radiant type pyrotechnics detection probe 1 is connected by cable and fire extinguishing system host 7
It connects, fire extinguishing system host 7 is connect with train network system 8, simultaneously to train network system by the indoor temperature field real-time delivery of visitor
It is shown on driver's display screen 9；Fine mist spray head 2 passes through the water tank 4 and nitrogen cylinder 5 installed under steel pipe 3 and solenoid valve 6 and vehicle
Connection, fire extinguishing system host 7 are connect with solenoid valve 6, and the working condition of fine mist spray head 2 is passed to train network system 8 simultaneously
It is shown in driver's display screen 9；Fire extinguishing system host is according to alarm threshold value prefabricated in advance and combines radiant type pyrotechnics detection probe
Fire alarm occurs in guest room, and warning message is shown on driver's display screen for the temperature information detected；It is alarming
In 3 seconds, fire extinguishing system host 7 controls water tank 4 and nitrogen cylinder 5 by solenoid valve 6, water and nitrogen is filled with steel pipe 3, and lead to
It crosses fine mist spray head 2 and heavy pressure fine spray is sprayed to fire position, complete active suppression.
Referring to Fig. 2, radiant type pyrotechnics detection probe is obtained the indoor thermo parameters method of visitor, is used by principle of infrared radiation
In the information on fire of (especially concealment part, be blocked position) in perception guest room；And thermo parameters method is transmitted by data
For optical fiber real-time delivery to fire extinguishing system host, fire extinguishing system host receives the temperature field information of radiant type pyrotechnics detection probe, and
It passes information to train network system and is shown on driving position；Meanwhile fire extinguishing system host is according to preset alarm threshold value
And judge whether fire behavior occurs really in conjunction with decision logic, when detecting that temperature more than threshold value and for 10 seconds, while having 2 phases
When adjacent radiant type pyrotechnics detection probe is detected simultaneously by the information, it is determined that fire occurs really, otherwise it is assumed that wrong report；When true
Recognize after fire behavior occurs, the nitrogen in the water and nitrogen cylinder in water tank is mixed and be filled with by fire extinguishing system host-initiated solenoid valve
Steel pipe, fire extinguishing system host-initiated detects fine mist spray head of the radiant type pyrotechnics detection probe with group of fire behavior, by high pressure fine
Atomized water spray is in fire behavior region.
