Second cathode grafting contact of the first cathode grafting contact electrical connection.Power battery is as energy-storage system, electrion electricity
Stream and charging current are all very big, up to 200A or so, so safety is most important.Once fire occurs, consequence will be quite tight
Weight is very helpful to personnel escape if can find that power battery catches fire as early as possible.
Domestic and international existing product detection power battery cabin fire is the height by temperature to determine whether catching fire, this side
The device layout of formula is simple, it is only necessary to a temperature sensor, but since the temperature in high-power operation can be very high, and
Temperature can may not also conduct immediately the position being arranged to temperature sensor when hidden fire occurs, because in the prior art for fire
The means for detecting judgement are single, and inaccuracy is easy to produce wrong report.
Summary of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide a kind of power battery cabins to use
Fire detection automatic alarm system.
The purpose of the present invention can be achieved through the following technical solutions:
A kind of power battery cabin fire detection automatic alarm system, including fire alarm host and fire detector, institute
It states fire detector to be placed in power battery cabin and connect with fire alarm host, the fire detector includes detection control
Device, temperature sensor, gas sensor and particulate matter sensors, the controller for detection are passed with temperature sensor, gas respectively
Sensor is connected with particulate matter sensors；
The battery flat that temperature, gas sensor acquire in the battery flat that the controller for detection is acquired according to temperature sensor
Carry out fire is compared with initiation combustion product for the solid particle ingredient of composition of gases within and particulate matter sensors liniment
Identification sends fire alarm signal to fire alarm host when a fire.
The fire alarm host include for fire detector failure or it is not connected when the trouble light that lights.
The fire alarm host includes for lighting when receiving the fire alarm signal sent by calamity alarm host machine
Alarm lamp.
The fire alarm host includes buzzer.
The temperature sensor is infrared temperature sensor.
The fire alarm host is connect with vehicle-mounted ECU, and is receiving the fire alarm letter sent by calamity alarm host machine
Number when by vehicle-mounted ECU cut off power battery electricity output.
The system also includes extinguishing device, which is set in power battery cabin and connects with fire alarm host
It connects, the fire alarm host is actuated for putting out a fire when receiving the fire alarm signal sent by calamity alarm host machine.
Compared with prior art, the invention has the following advantages:
1) being configured with temperature sensor, gas sensor and particulate matter sensors can be respectively to gas in temperature, battery flat
Body ingredient and solid particle ingredient are analyzed and the combustion product of initial stage is compared, and are calculated using artificial intelligence
Method reduces False Rate whether judging fire formation.
2) temperature sensor is infrared temperature sensor, directly can carry out thermometric to heating pad, reduce because of heat transfer mistake
Detection lag caused by journey.
3) electricity of power battery is cut off by vehicle-mounted ECU when receiving the fire alarm signal sent by calamity alarm host machine
Output avoids lasting heating effect of current from providing heat source.
4) extinguishing device is configured, has unmanned fire processing capacity.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention；
Wherein: 1, fire detector, 2, fire alarm host, 3, extinguishing device.
Specific embodiment
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.The present embodiment is with technical solution of the present invention
Premised on implemented, the detailed implementation method and specific operation process are given, but protection scope of the present invention is not limited to
Following embodiments.
A kind of power battery cabin fire detection automatic alarm system, as shown in Figure 1, including fire alarm host 2 and fire
Detector 1, fire detector 1 are placed in power battery cabin and connect with fire alarm host 2, and fire detector 1 includes detection
Controller, temperature sensor, gas sensor and particulate matter sensors, controller for detection are passed with temperature sensor, gas respectively
Sensor is connected with particulate matter sensors；Temperature, gas sensor in the battery flat that controller for detection is acquired according to temperature sensor
The battery flat composition of gases within of acquisition and the solid particle ingredient of particulate matter sensors liniment are carried out with initiation combustion product
It compares and carries out fire identification, when a fire, send fire alarm signal to fire alarm host 2.
It can be respectively in temperature, battery flat due to being configured with temperature sensor, gas sensor and particulate matter sensors
Gas componant and solid particle ingredient are analyzed and the combustion product of initial stage is compared, and are calculated using artificial intelligence
Method reduces False Rate whether judging fire formation.
Fire alarm host 2 include for 1 failure of fire detector or it is not connected when light trouble light, for connecing
The alarm lamp lighted when receiving the fire alarm signal sent by calamity alarm host machine.In addition, fire alarm host 2 further includes buzzing
Device.Temperature sensor is infrared temperature sensor, directly thermometric can be carried out to heating pad, caused by reducing because of heat transfer process
Detection lag.
Fire alarm host 2 is connect with vehicle-mounted ECU, and when receiving the fire alarm signal sent by calamity alarm host machine
The electricity output that power battery is cut off by vehicle-mounted ECU avoids lasting heating effect of current from providing heat source.System further includes fire extinguishing dress
Set 3, which is set in power battery cabin and connect with fire alarm host 2, fire alarm host 2 receive by
It is actuated for putting out a fire when the fire alarm signal that calamity alarm host machine is sent, has unmanned fire processing capacity.
The key problem in technology of this system is fire detection alarm accuracy, high reliablity.
The initialization of system energization aft engine, alarm lamp, trouble light are lighted, while buzzer rings a sound, shows each fire later
1 state of fire detector.Each fire detector 1 also starts self-test after being powered, send out current state.If fire detector 1 does not connect
Enter, connecting fault or detector internal fault, alarm host machine screen are shown " failure ", while yellow trouble light is lighted, should be timely
It checks and ensures that fire detector 1 works normally.
If fire behavior occurs for somewhere, fire-alarm is alarmed at this, and the corresponding detector's status information of alarm host machine is from " just
Often " become Alarm, red alarm lamp is lighted, and the alarm sound of " serge serge serge " is simultaneously emitted by, must parking checking as early as possible.Fire alarm
After releasing, the corresponding state of alarm host machine becomes " normal " from Alarm, while buzzer stop alarm.Fire detector 1 is logical
Green state indicator light is to be always on after electricity, enters normal monitoring state later.When detecting fire behavior or high temperature, fire detector
1 issues sound-light alarm, while exporting alarm signal.After restoring normal, the indicator light is always on for 1 green state of fire detector, red
Indicator light extinguishes.
