Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, with reference to embodiments, to this
Utility model is further elaborated.It should be appreciated that specific embodiment described herein is only used to explain this practicality
It is novel, it is not used to limit the utility model.
1 the structure of the utility model is explained in detail to attached drawing 6 below in conjunction with the accompanying drawings.
The SCM Based smoking cessation reminiscences is provided with the smoke sensor device for being detected to indoor smog concentration
1；
It is electrically connected with smoke sensor device 1, for the amplifying circuit 2 for being amplified the smoke signal detected；
It is electrically connected with amplifying circuit 2, for data to be carried out with the SCM system 3 of operation and processing；
It is electrically connected with SCM system 3, for the digital-scroll technique tube drive circuit 4 that numerical value carries out output display will to be detected；
It is electrically connected with SCM system 3, is used to implement the buzzer drive circuit 5 of number detection signal alarm；
It is electrically connected with SCM system 3, is used to implement the state instruction circuit for lamp 6 of data optical signal build.
As the preferred embodiment of the utility model, the smoke sensor device 1 uses heater-type smoke sensor device.
As the preferred embodiment of the utility model, the digital-scroll technique tube drive circuit 4 uses eight sections of common cathode numbers
Code pipe is shown.
As the preferred embodiment of the utility model, the buzzer drive circuit 5 passes through 8550 base stage of PNP triode
Serial resistance is connect with microcontroller P20 ports.
Smoke sensor device 1 and amplifying circuit 2 such as Fig. 3.The measuring cell of this circuit uses heater-type smoke sensor device 1MQ-
2, in the case of no smog, the resistance value of smoke sensor device 1 is higher (20K or so), its resistance value is anxious when smog enters sensor
Play declines, and A, B both end voltage decline.
1 output signal of smoke sensor device is generally fainter, needs to be amplified it by front end circuit, filter, electricity
Heibei provincial opera is whole, meets requirement of the microcontroller to input signal.Since system is powered using unipolarity, so using in-phase proportion
Amplifying circuit 2, it is possible to reduce hardware spending.Pre-amplification circuit 2 uses operational amplifiers of the LM324 as circuit, and price is low
It is honest and clean, using it is simple the advantages that than more prominent.LM324 is single slice high-gain four-operational amplifier, can be in compared with wide-voltage range
It works under single supply or dual power supply, source current very little and unrelated with supply voltage.Four amplifier consistency are good, and input is inclined
Leakage resistance is temperature-compensating, is also not required to external frequency compensation, can accomplish that output level is compatible with digital circuit.
The signal Vi come out from the upper end of sensor passes through the in-phase input end of operational amplifier, but to ensure what is introduced
It is negative-feedback, output voltage Vo is connected to inverting input by resistance R2, meanwhile, inverting input is connected to reference by resistance R1
Voltage Vref.Due to introducing depth series voltage negtive backword, the input impedance of circuit is very high, and output impedance is very low.It is high
Input impedance can reduce influence of the amplifying circuit 2 to front-end circuit, while low output impedance can also improve the anti-of itself
Interference, this is clearly advantageous to the design of other modules in circuit.This amplifying circuit 2 has also added reference voltage, introduces zero
Regulatory function can be adjusted more easily due to Zero change problem caused by different sensors in this way.It utilizes and slides variable resistance
Device generates a reference voltage Vref, recycles Voltage Reference end of the voltage follower control source to operational amplification circuit 2.
So adjust slide rheostat, it is possible to be directly changed the reference voltage of amplifying circuit 2.And the effect of voltage follower is only used
Carry out matching impedance, prevent the influence of R1 and R2 to slide rheostat output voltage.
When detecting combustible gas or smog, signal through overvoltage relatively after export be high level digital signal, instead
Be low level.In order to which microcontroller preferably carries out the processing of signal, this circuit also adds the triode of a NPN, there is height
The effect of low transition.1 signal detection of smoke sensor device so just completes.
Digital-scroll technique tube drive circuit 4, as shown in Figure 4.Using eight sections of common cathode numeral methods, circuit uses model
The red high-quality super bright charactron of 0.8 cun of 1 common anode of the general board of light for CPS08011BR, by P0 mouthfuls of output seven segment code drivings of microcontroller
Charactron.Digital pipe display circuit is mainly used for showing the numerical value of smokescope and temperature height, secondly, button setting smog and
The prompting range of temperature is also to be shown by charactron.
Buzzer drive circuit 5, as shown in Figure 5.Circuit passes through 8550 base stage of PNP triode, one resistance of series winding and monolithic
Machine P20 ports connect, and audible alarm is realized by microcontroller control buzzer.Warning device uses electromagnetic type passive buzzer HC-
12075-B, parameter characteristic are as follows：
Rated voltage：1.5V
Rated current：=<10mA~=<70Ma
Sound pressure level：>=75~>=85
Resonant frequency：2048Hz
Coil resistance：± 2 Ω of 6.5 ± 1 Ω~60.
State instruction circuit for lamp 6, as shown in Figure 6.Green light is always on expression normal condition, flammable smokescope pole in environment
It is low；Blinking red lamp represents that smokescope is more than alarm minimum predetermined value in environment, reminds user to stop smoking.
Program flow diagram is as shown in Figure 7.After program initialization, sensor starts to preheat, and does not use for a long time, sensing
Device cannot normally acquire the information of smog, and system will enter monitor state after preheating.In the program of entire smoking cessation reminiscences, by
Microcontroller judges the concentration value of smog, more than setting value range when, buzzer call, LED light flicker is come with this to smoking
Human hair go out remind.
SCM Based smoking cessation reminiscences detects the dense of smog mainly by 51 microcontrollers core in order to control by sensor
Degree, by amplifying circuit 2, by A/D converter analogue transformation into digital quantity, using the judgement of microcontroller, concentration value surpasses
When crossing the range of setting, buzzer starts to pipe, and sound is more and more rapid, and with blinking red lamp.Because people is to variation
Signal it is more sensitive, so variation sound and light be easier the attention for causing smoking user.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
