Pole pipe VD5, resistance R1～R2 and transistor V1, the measurement electrode A of gas sensor QM is with steady
The outfan of depressor IC1 connects, and measures electrode B and connects with slide rheostat RP1 and diode VD5
Rear ground connection, one end of heater strip is connected with the outfan of manostat IC1, and the other end becomes with sliding
Ground connection after resistance device RP2 series connection；
The measurement electrode B of gas sensor QM is by the base stage of resistance R1 and transistor V1 even
Connect；The colelctor electrode of transistor V1 is connected with the outfan of manostat IC1, emitter stage and resistance R2
Ground connection after series connection；
The emitter stage of transistor V1 is connected with the input of manostat IC2 in alarm module, voltage stabilizing
The outfan of device IC2 is connected with the base stage of transistor V2, and speaker BL is series at manostat IC1's
Between the colelctor electrode of outfan and transistor V2, the grounded emitter of transistor V2.
The base stage of described transistor V1 connect with electric capacity C2 after ground connection.
Described speaker BL replaces with buzzer.
Described manostat IC1 and/or manostat IC2 is three terminal integrated voltage stabilizer.
Described power module by civil power through Transformer Rectifier and filter after again through manostat IC1 to smog
Detection module and alarm module are powered.
The beneficial effects of the utility model are: warning system is installed on the top of car, smog
Detection module monitors the smokescope in car in real time, reaches when having people's smoking and concentration in car
When presetting smokescope alarming value, alarm module sends alarm sound, and smoker is timely in prompting
Stop smoking, and cigarette is extinguished, it is ensured that the air quality in car.
Accompanying drawing explanation
Fig. 1 is circuit connection diagram of the present utility model.
Detailed description of the invention
The technical solution of the utility model is described further below, but claimed scope is not
It is confined to described.
A kind of car smog automatic alarm system as shown in Figure 1, including power module, smog
Detection module and alarm module, Smoke Detection module and alarm module are powered by power module；Institute
State Smoke Detection module and include gas sensor QM, slide rheostat RP1～RP2, diode
VD5, resistance R1～R2 and transistor V1, the measurement electrode A of gas sensor QM and manostat
The outfan of IC1 connects, and measures electrode B and connects be followed by with slide rheostat RP1 and diode VD5
Ground, one end of heater strip is connected with the outfan of manostat IC1, the other end and slide rheostat
Ground connection after RP2 series connection；The measurement electrode B of gas sensor QM is by resistance R1 and transistor V1
Base stage connect；The colelctor electrode of transistor V1 is connected with the outfan of manostat IC1, emitter stage
Ground connection after connecting with resistance R2；The emitter stage of transistor V1 and manostat IC2 in alarm module
Input connects, and the outfan of manostat IC2 is connected with the base stage of transistor V2, speaker BL
Being series between the outfan of manostat IC1 and the colelctor electrode of transistor V2, transistor V2 sends out
Emitter grounding.The base stage of described transistor V1 connect with electric capacity C2 after ground connection.
Described speaker BL replaces with buzzer.
Described manostat IC1 and/or manostat IC2 is three terminal integrated voltage stabilizer.
Described power module by civil power through Transformer Rectifier and filter after again through manostat IC1 to smog
Detection module and alarm module are powered.
Power module in this utility model by the 220V alternating current of civil power through transformator T blood pressure lowering,
After diode VDl mono-VD4 rectification, electric capacity C1 filtering and manostat ICl voltage stabilizing, produce direct current 12V
Voltage, supply Smoke Detection module in gas sensor QM, manostat IC2 and transistor V1,
Transistor V2 etc..Gas sensor QM is when being not detected by smog, and it measures electrode A, B two
Resistance between end is very big, and the voltage measuring electrode B end is relatively low, and transistor V1 is in cut-off shape
State, speaker BL not sounding.When gas sensor QM detects smog, its measurement electrode A,
Resistance between B two ends diminishes so that it is the voltage measuring electrode B end raises, and transistor VI turns on,
The output of its emitter stage triggers high level, makes manostat IC2 work, and speaker BL sends loud
Prompt tone, can will be prompted to sound and be set to " in order to other people are healthy, the most not inhale in car
Cigarette ... " language warning.After smog disperses, the measurement electrode A of gas sensor QM,
Recover high value between B, make transistor V1 end less than emitter voltage because of base voltage,
Chimes of doom stops.
This utility model circuit structure is simple, can monitor the smokescope in car, when in car
When someone smoking and concentration reach to preset smokescope alarming value, this device sends alarm
Sound, it is ensured that the air quality in car, economical and practical and practical function.
