Description
Technical field
The present invention relates to railway vehicle air conditioner technical fields, in particular to dynamic side of the useless Volleyball Association based on fire cigarette sense detection
Method.
Background technique
In rail vehicle, air-conditioner set is blown by supply air duct and air outlet into compartment, is sent by return airway
It is back to air-conditioning, air circulation utilizes.Air-conditioner set conveys fresh air into compartment by fresh air air port, guarantees air in a car compartment
Freshness.While inputting fresh air into compartment, there are positive pressure, the arranging device that gives up is opened for interior, and interior exhaust gas is discharged
And adjust interior air pressure.When car is without positive pressure, air door closes air door by the gravity of itself.
The arranging device that gives up on current track vehicle mostly uses gravity-flow ventilation exhaust mode, opens air door by interior positive pressure, will
Exhaust gas drains into outdoor.But exist when vehicle outgoing is lit a fire under the state of emergency such as police, flue gas, there are positive pressures for car, and useless exhaust door can not
The case where closing, the outer smog of vehicle enters the room；Or interior generation fire alarm, useless exhaust door can not close, outside air enters the room
Play combustion-supporting effect.Therefore, how to solve under smog, fire condition, guarantee that useless arranging device be not affected by other factors
Lower closing is the current problem to be solved of those skilled in the art.
Found through inspection, Chinese utility model patent ZL201220056548.4) patent, patent searching inventive point is useless row
Device is mounted on the under-seat in compartment, is not take up the space in compartment；In such a way that lower part outlet air is entered the wind in two sides, outlet air
Outside mouth through train, the structures such as useless exhausting duct are omitted, alleviate vehicle weight；And it is equipped with Electric air valve, is lit a fire in vehicle outgoing
The emergencies such as calamity driver can will be isolated outside useless arranging device and vehicle, guarantee passenger inside the vehicle's safety.
However useless arranging device needs driver to judge and control with being isolated outside vehicle, the degree of automation is low, can not be applied to nothing
In people's driving cycles, there is also the possibility of certain maloperation.
Summary of the invention
The purpose of the present invention provides a kind of based on rail vehicle fire cigarette primarily directed to above-mentioned the problems of the prior art
The useless row's linkage circuit for feeling detection detects fire conditions with fire cigarette sense detection device under vehicle in the car by installing, by fire
Alarm signal is exported to fire alarm control unit, and the opening and closing of useless exhaust door is finally controlled by fire alarm control unit.
In order to solve the above technical problems, the useless Volleyball Association provided by the invention based on rail vehicle fire cigarette sense detection is dynamic
Circuit, including useless row's power supply and the useless arranging device being connect with useless row's power supply, it is characterised in that: further include fire alarm control unit,
Fire cigarette sense detector and the detection of the first fire alarm under the interior fire cigarette sense detector that is connect with fire alarm control unit, vehicle
Relay is closed, the detection of the first fire alarm is closed between the normally-closed contact useless row's power supply of series connection access of relay and useless arranging device
Circuit in.
The invention further relates to a kind of useless row's interlock methods based on rail vehicle fire cigarette sense detection, utilize above-mentioned useless Volleyball Association
Dynamic circuit is realized, when fire cigarette sense detector detects smog under interior fire cigarette sense detector or vehicle, is transmitted signal to
Fire alarm control unit, fire alarm control unit drive fire alarm detection to close the actuating of relay, disconnect its normally-closed contact,
The current supply circuit of useless arranging device is cut off, and the arranging device that gives up closes air door, realizes that fire cigarette sense detection and useless Volleyball Association are dynamic；When interior fire
When fire cigarette sense detector does not detect smog under calamity cigarette sense detector and vehicle, fire alarm control unit detects fire alarm
Relay electric-loss is closed, its normally-closed contact is closed, the current supply circuit access for the arranging device that gives up, the arranging device that gives up opens air door.
In addition, a kind of rail vehicle is also claimed in the present invention, it is characterised in that: have above-mentioned based on rail vehicle fire
Useless row's linkage circuit of calamity cigarette sense detection.
When no fire occurs, exhaust door opening of giving up is discharged interior exhaust gas, realizes and divulge information with the external world and guarantee interior air pressure.
When vehicle, which issues, lights a fire calamity, fire alarm detection is closed relay contact and is disconnected, and air door is closed, and prevents external fire smog from entering
It is interior.When car occur fire when, fire alarm detection close relay contact disconnect, air door close, prevent outside air into
Enter to play the role of combustion-supporting.
The system is independently of air-conditioning system, and in the car or vehicle is issued and lit a fire under the state of emergency such as police, flue gas, can directly pass through
The useless row of fire cigarette sense detection system control closes, and prevents smog from spreading, guarantees guest room air quality.
Compared with prior art, it the present invention is based on the useless arranging device of fire cigarette sense detection system linkage, realizes when interior or vehicle
Outgoing is lit a fire calamity, and useless arranging device can not be influenced to close air door by environment inside car, on the contrary, ought occur within the interior or exterior of the vehicle without fire
When, useless exhaust door is kept open, it can effectively guarantee guest room in normal state or under the state of emergency, air quality,
Passenger is improved to ride comfort level.
Detailed description of the invention
Fig. 1 is that circuit diagram moves in useless Volleyball Association.
Fig. 2 is that flow chart moves in useless Volleyball Association.
Specific embodiment
Embodiments of the present invention are illustrated with reference to the accompanying drawing.
