Description

No smoking voice warning device

[technical field]

The utility model relates to electronic circuit field, particularly be a kind of no smoking voice warning device.

[background technology]

Along with the raising of health of people level, also more and more higher to the health standards of public environment, country also progressively strengthens Environmental Monitoring Network construction to improve environmental monitoring ability.Particularly smoking cannot be imagined the harm of human and environment, and as everyone knows, Smoking is harmful to your health, there are 1,300,000,000 smokers in the whole world, directly die from the diseases induced population of smoking up to 5,000,000 people every year, there are 3.5 hundred million smokers in China, annual corresponding dead population about 1,000,000 people.It not only endangers the life of the mankind, also causes serious impact to environment simultaneously, and in public places, the mark of no matter be on bus, or in business unit, be seen everywhere " no smoking ", but its effect is all not good, and a lot of people turns a blind eye to.In addition, have the unconscious smoking of people in public places, if artificially prevented, unavoidably can be more awkward, especially in the place such as bus or office, so we must improve in the past mode to warn people, no smoking.

Therefore, for avoiding above-mentioned technical matters, the necessary one that provides has structure improved no smoking voice warning device, to overcome described defect of the prior art.

[utility model content]

In order to overcome above shortcomings part in prior art, the purpose of this utility model is to provide a kind of no smoking voice warning device.

In order to reach above-mentioned object, the utility model adopts following concrete technical scheme: no smoking voice warning device, include power circuit, smoke collection circuit A/D change-over circuit, single-chip minimum system and voice playing module, the output signal of described power circuit is transferred to smoke collection circuit and single-chip minimum system, the output signal of described smoke collection circuit is sent to single-chip minimum system through A/D change-over circuit, and the output signal of described single-chip minimum system is sent to voice playing module.

Described smoke collection circuit adopts MQ-2 smoke transducer P 1 collection signal, and the output terminal of described MQ-2 smoke transducer P 1 is connected to the input end of 555 time-base integrated circuit U1.

Described A/D change-over circuit adopts ADC0832 chip U2.

Described single-chip minimum system adopts AT90S23 13 chip U3.

Described voice playing module adopts ISDl700 speech chip U4.

The utility model advantage is compared with prior art: the utility model adopts the smoke transducer of smoke collection circuit to gather smoke signal, and this signal is sent to single-chip minimum system, single-chip minimum system makes voice playing module send set no smoking and so on voice prompt, reminds the conscious stopping smoking of smoker.

[accompanying drawing explanation]

Fig. 1 is frame assumption diagram of the present utility model;

Fig. 2 is circuit theory diagrams of the present utility model;

Below in conjunction with accompanying drawing, the utility model is described in further detail.

[embodiment]

In order to explain the technical solution of the utility model further, below by specific embodiment, the utility model is elaborated.

As shown in Figure 1, one of the present utility model no smoking voice warning device, include power circuit, smoke collection circuit, A/D change-over circuit, single-chip minimum system and voice playing module, the output signal of described power circuit is transferred to smoke collection circuit and single-chip minimum system, the output signal of described smoke collection circuit is sent to single-chip minimum system through A/D change-over circuit, and the output signal of described single-chip minimum system is sent to voice playing module.Power circuit produces the operating voltage needed for all parts, make normally to work, smoke signal is received by smoke transducer collection, and this signal collected after the conversion of A/D change-over circuit, pass to single-chip minimum system, make voice playing module work by single-chip minimum system, and send the voice message setting that no smoking and so on.

As shown in Figure 2, described smoke collection circuit adopts MQ-2 smoke transducer P1 collection signal, the output terminal of described MQ-2 smoke transducer P1 is connected to the input end of 555 time-base integrated circuit U1, the gas sensitive that MO-2 smoke transducer P1 uses is the tin ash that conductivity is lower in clean air, when there is smog in environment residing for MO-2 smoke transducer P1, the conductivity of MO-2 smoke transducer P1 increases with the increase of smokescope in air, and sensitivity is very high.

When MO-2 smoke transducer P1 does not detect smog, resistance is comparatively large, and the 2nd pin of 555 time-base integrated circuit U1 is high level, its 3rd pin no-output, and rearward part does not work; When there being people's smoking, when MO-2 smoke transducer P1 detects smog, between MO 1 smoke transducer P1, resistance diminishes, and makes the 2nd pin voltage drop of 555 time-base integrated circuit U1, and its 3rd pin is exported by signal, passes to A/D change-over circuit through resistance R5 current limliting.

Described A/D change-over circuit employing AD (; 0832 chip U2.Its volume is little, and compatible strong, cost performance is high.Mainly as signal conversion module in the utility model, after the smoke signal conversion that MO 1 smoke transducer P1 is collected, pass to single-chip minimum system, make single-chip minimum system make steering order.

Described single-chip minimum system adopts AT90S23 13 chip U3, as Master control chip in the utility model, mainly by the signal after converted for A/D change-over circuit, by the form of instruction, LED is glimmered to report to the police, make to know dangerous near personnel, dependent instruction is passed to voice playing module simultaneously.

Described voice playing module adopts ISDl ' 700 speech chip U4, ISDl700 speech chip U4 not only has more selection (from 20 seconds to 240 seconds) in record length, and functionally inherit all recording and reproducing functions of chip in earlier stage, and add some prompt facility of hommization and the precise manipulation to memory address more, ISDl700 speech chip U4 inside includes automatic growth control, the preposition expander of microphone, speaker drive circuit, the comprehensive integration system function of oscillator and internal memory etc., so use this chip more to save amplifier, the circuit such as speaker drive, make circuit simpler, mainly complete in the present system and pass the signal of coming by single-chip minimum system, warning sound external loudspeaker being sent set.

But above-mentioned embodiment is exemplary, being to better enable those skilled in the art understand this patent, can not being interpreted as it is restriction this patent being comprised to scope; As long as according to this patent disclose any equivalent change done or the modification of spirit, all fall into the scope that this patent comprises.
