Description of the drawings
Fig. 1 is the system global structure schematic diagram of the present invention for preventing the stranded death of interior infant.
Specific implementation mode
Present invention will be described in further detail below with reference to the accompanying drawings, to enable those skilled in the art with reference to specification text
Word can be implemented according to this.
As shown in Figure 1, the present invention provides a kind of systems preventing the stranded death of interior infant comprising occupant
Identification module, connect controller module 200, when for monitoring dead ship condition whether someone in the car；The occupant knows
Other module includes：Thermal infrared human inductor 110, is installed on roof；Sound transducer 120, is installed on roof；Pressure
Force snesor 130 is installed below automobile back row cushion.When thermal infrared human inductor 110 monitors interior someone, or
Sound transducer 120, which recognizes car, has the crying of infant or pressure sensor 130 to monitor have object moving on seat
Dynamic, as long as three of the above sensor has one kind to monitor that personnel are located at car, controller module judges that someone is trapped in car.It answers
Identify that car whether with the presence of personnel, improves knowledge simultaneously with thermal infrared human inductor, sound transducer and pressure sensor
Other accuracy avoids the failure for leading to whole device because of a kind of failure of sensor.
In another embodiment, occupant's identification module further includes：Infrared rays survey sensor 140, is set to vapour
The corresponding roof of vehicle rear row seat, for measuring infant's sitting height.
Environment inside car monitoring modular, connects controller module 200, and the environment inside car monitoring modular includes：Oxygen concentration
Sensor 310 is monitored, roof is mounted on, and above back row seat of automobile, for the oxygen concentration (oxygen hundred in monitoring car
Divide content)；Carbon monoxide monitors sensor 320, air-conditioner air-outlet is installed on, for monitoring carbonomonoxide concentration, Yi Jiwen
Degree monitoring sensor 330, is mounted on roof, and above back row seat of automobile, for monitoring vehicle interior temperature.Due to infant
Vehicle heel row generally is rided in, therefore, by oxygen concentration sensor and temperature sensor as above rear row seat, is monitored with improving
As a result accuracy.
Automobile CAN-bus module 400 connects controller module 200, and sends car door, engine to controller module
Signal, wheel speed signal and accumulator signal.
External communication module 500, built-in GPRS transmitters, the external communication module connects controller, in urgent feelings
Emergence message is externally sent under condition.
In addition, the controller module 200, also fills with automobile center console display screen, sound equipment, air-conditioning, headlight, acoustic signal
Set (loudspeaker), vehicle window control device, engine, clutch, accelerator pedal, speed changer be connected.
When the judgement of controller module 200 has infant to lock into car, if sound transducer 120 monitors baby simultaneously
Child makes a sound, such as crying, and the interior sound equipment of controller module control and console display screen are allowed to play music nursery rhymes
Deng to pacify the mood of stranded infant.Vehicle interior temperature is monitored by temperature sensor 330, when to reach 28 Celsius for vehicle interior temperature
Du or more or at 5 degrees Celsius or less, controller module 200 is just opened interior air-conditioning and is made it stable to adjust vehicle interior temperature
Between 20-24 degrees Celsius.By carbonomonoxide concentration in 320 monitoring car of carbon monoxide transducer, when carbonomonoxide concentration is more than
When 20ppm, controller module 200 closes the outer circulation of air-conditioning, is switched to interior cycle, prevents occupant's anthracemia.
The present invention also provides a kind of control methods for the system for preventing the stranded death of interior infant, which is characterized in that
Include the following steps：
Step 1：Automobile CAN-bus module 400 monitors car door, engine and wheel speed information and is transmitted to controller module.
Step 2：Whether the wheel speed information that sensor assembly is arrived according to automobile bus module monitors judges automobile in parking
State；In the present embodiment, when automobile CAN-bus module 400 monitors that car door is closed, engine is in flame-out shape
State, when wheel speed is less than 3km/h, controller judges that automobile is in dead ship condition.
Step 3：If automobile is in dead ship condition, occupant's identification module starts, and monitors whether someone in vehicle
It is interior；When thermal infrared human inductor 110 monitors that interior someone or sound transducer 120 recognize car and have infant's
Crying or pressure sensor 130 monitor have object in movement on seat, as long as three of the above sensor has one kind to monitor
There are personnel to be located at car, controller module judges that someone is trapped in car.
Step 4：If someone is in the car, environment inside car monitoring modular starts, and the oxygen concentration in monitoring car, an oxygen
Change concentration of carbon and temperature.
Step 5：Controller calculates the hazard index of infant according to environment inside car situation；Take corresponding processing plan
Slightly.In the present embodiment, the hazard index of infant is calculated according to environment inside car situation and down time；
Wherein, C0(for example, oxygen concentration is 20% in in-vehicle air, then 20 are taken to bring into formula for interior oxygen concentration
Calculate), C1For interior carbonomonoxide concentration, unit ppm, T are vehicle interior temperature, unit DEG C, t be infant be detained in the car when
Between, unit h.
Later, controller module 200 takes corresponding processing strategy further by calculated hazard index I：
As 0 ＜ I≤0.5, degree of danger is relatively low；At this point, can be given a warning to car owner by communication module；Notify car owner
It comes back, is succoured as early as possible.
As 0.5 ＜ I≤1, it is in relatively hazardous state；At this point, being given a warning to car owner by communication module and flickering vehicle
Lamp, while vehicle window can be opened a part, cause passerby to pay attention to；
As I ＞ 1, it is in abnormally dangerous state；At this point, flicker car light, control vehicle whistle, and vehicle window is opened completely.
Since the accumulator capacity of automobile is limited, if rescuer does not rush to slowly, accumulator electric-quantity consumption is easily caused
To the greatest extent, therefore work as automobile CAN-bus module 400 by accumulator signal transmission to controller module, controller module 200 judges electric power storage
When pond electricity will exhaust, engine start will be controlled, progress is idle, to charge to accumulator.Meanwhile to avoid baby young
Youngster misses stepping on clutch, accelerator pedal, the components such as speed changer, controller module 200 will to clutch, accelerator pedal, speed changer into
Row locking, only can just unlock after car door is again turned on.
In another embodiment, further include the sitting height of the pressure and infant transmitted according to pressure sensor, danger is referred to
Number is corrected, and correction coefficient is：
Wherein, h is infant's sitting height, unit cm；F is when infant is static to the pressure as generation, unit N.Correction
Hazard index afterwards is I '=η I.Later, controller module takes corresponding strategy according to the hazard index after correction.Due to
The degree of danger of infant is somewhat dependent upon its age size, can be sentenced by sitting height and the pressure generated to seat
Break and its substantially age hazard index is corrected on this basis, the reliability of judgement can be further increased.
Although the embodiments of the present invention have been disclosed as above, but its is not only in the description and the implementation listed
With it can be fully applied to various fields suitable for the present invention, for those skilled in the art, can be easily
Realize other modification, therefore without departing from the general concept defined in the claims and the equivalent scope, the present invention is simultaneously unlimited
In specific details and legend shown and described herein.
