Device, temperature sensor, gas sensor and particulate matter sensors, the controller for detection pass respectively with temperature sensor, gas
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 when a fire, fire alarm signal is sent to fire alarm host.
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 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 believed receiving by the fire alarm that calamity alarm host machine is sent
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 utility model has the advantages that：
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 whether judging fire formation, reduces False Rate.
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.
Description of the drawings
Fig. 1 is the structure diagram of the utility model；
Wherein：1st, fire detector, 2, fire alarm host, 3, extinguishing device.
Specific embodiment
The utility model is described in detail in the following with reference to the drawings and specific embodiments.The present embodiment is with the utility model
Implemented premised on technical solution, give detailed embodiment and specific operating process, but the guarantor of the utility model
Shield range 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 are connect with fire alarm host 2, and fire detector 1 includes detection
Controller, temperature sensor, gas sensor and particulate matter sensors, controller for detection pass respectively with temperature sensor, gas
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, fire alarm signal is sent 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 whether judging fire formation, reduces False Rate.
Fire alarm host 2 include for 1 failure of fire detector or it is not connected when light trouble light, for connecing
Receive the alarm lamp lighted during 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 can carry out thermometric to heating pad, reduce caused by heat transfer process

1 state of fire detector.Each fire detector 1 also begins to 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 display " failure ", while yellow trouble light is lighted, it 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 is simultaneously emitted by the alarm sound of " serge serge serge ", 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 is always on after electricity, later into normal monitoring state.When detecting fire behavior or high temperature, fire detector
1 sends out sound-light alarm, while output alarm signal.After restoring normal, 1 green state indicator light of fire detector is always on, red
Indicator light extinguishes.
