Abstract
The utility model discloses a dangerous driving prevention device of automobile. The dangerous driving prevention device of the automobile comprises an alcohol sensor, and is characterized in that the alcohol sensor is sequentially connected with an amplifying circuit, a filtering circuit and an A/D converter, the A/D converter is further connected with an input end of a single chip microcomputer, the input end of the single chip microcomputer is further connected with a transformer, an output end of the single chip microcomputer is respectively connected with an ignition relay and an alarm chip, and a power source is connected on the transformer. When a driver gets on the automobile and drives the automobile, alcohol content of a cab is detected, when a system confirms that the drivers drives the automobile while intoxicated, an ignition system of the automobile is closed through controlling of a computer, and the driver is prevented from driving while intoxicated. When the driver uses a mobile phone in the period of driving, whether a driving behavior is correct or not is judged through detecting pressure exerted on a steering wheel by the driver, when the system confirms the irregular driving, the driver is reminded not to drive dangerously through language, and occurrence of accidents is prevented.
Description
Technical field
The utility model relates to the automotive safety technology, particularly a kind of dangerous driving prevention device for automobiles.
Background technology
Vehicle under steam, the operation lack of standardization of navigating mate will influence traffic safety, uses telephone bill manual manipulation bearing circle as when driving, even more severe patient drunk driving or drunk driving, can cause serious traffic accident, endangers self passenger and pedestrian's safety." law on road traffic safety " regulation, during behaviors such as the driver dials when driving, answering cell phone, to once detain 2 fens, but the Administrative Punishment of this light dynamics can not be contained the abnormal activity of driving fully, need a kind of device badly and remind the chaufeur standard to drive constantly.Therefore, the utility model has been announced a kind of dangerous driving prevention device for automobiles, can be under the situation of various chaufeur dangerous drivings timely reminder alerting navigating mate, correct operation lack of standardization, prevent the generation of accident.
Summary of the invention
Have in driving a car at chaufeur that driving is phoned with mobile telephone, the potential safety hazard of drunk driving or drunk driving, the utility model purpose is, a kind of dangerous driving prevention device for automobiles is provided, when chaufeur is being got on the bus the back during steering vehicle, by detecting the alcohol content of operator's compartment, and take appropriate measures and prevent that chaufeur from driving when intoxicated; When during chaufeur is being driven, using telephone bill manual manipulation bearing circle, be applied to pressure on the bearing circle by detecting chaufeur, judge whether dangerous driving of chaufeur, and when being judged as dangerous driving, remind the chaufeur standard to drive, prevent the generation of dangerous accident.
In order to realize above-mentioned task, the utility model adopts following technical scheme to be achieved:
A kind of dangerous driving prevention device for automobiles, comprise alcohol sensor, on the alcohol sensor successively with amplifying circuit, filter circuit, A the D conv be connected, A the D conv link to each other with the micro controller system input end again, the micro controller system input end also is connected with voltage transformer, and the micro controller system mouth is connected with ignition relay and alarm chip respectively; Also be connected with power supply on the voltage transformer.
The utility model also has following other technologies characteristics:
Described alcohol sensor adopts TP-3 type sensor, and the ADC0809 chip is adopted in the A/D conversion, and micro controller system adopts the 89C52 micro controller system.
Described pressure sensor adopts piezoelectric force transducer.
Described alarm chip is the PM5020 speech chip.
The utility model compared with prior art, but simple in structure, the low generalization of cost is strong.
Description of drawings
Fig. 1 is the structure principle chart of intelligent alcohol detector.
Fig. 2 is the driving principle figure of audio alert chip.
Below in conjunction with the drawings and specific embodiments the utility model particular content is described in further detail.
The specific embodiment
Referring to Fig. 1, a kind of dangerous driving prevention device for automobiles of the present utility model, comprise alcohol sensor, it is characterized in that: on the alcohol sensor successively with amplifying circuit, filter circuit, A the D conv be connected, A the D conv link to each other with the micro controller system input end again, the micro controller system input end also is connected with voltage transformer, and the micro controller system mouth is connected with ignition relay and alarm chip respectively; Also be connected with power supply on the voltage transformer.Whole device is installed on the operator's compartment top.Wherein the constant voltage power suspply part directly connects the 12V operating voltage of vehicle, and the air-sensitive sensing technology has mainly been adopted in the alcohol sensing part, by power gain, finishes the function to the alcohol concentration test.When gas sensor has been sensed alcohol concentration and has been exceeded standard, convert the analog signal of sensor to digital signal by the ADC0809 chip and be input to the 89C52 micro controller system, and then by the ignition system of Single-chip Controlling relay locked car; The 89C52 micro controller system outputs signal to the audio alert chip simultaneously, sends the voice suggestion chaufeur and is in the state of driving when intoxicated.
Further, the model that alcohol sensor is selected is TP-3, and it is the exhalation alcohol tester, this end instr is formed by nanoscale SnO2 and suitable doping mixture sintering, tool microballon formula structure, and application circuit is simple, resistance variations can be changed into an output signal, corresponding with alcohol concentration.TP-3 type sensor has high sensitivity to airborne low-concentration ethanol, adopts little handler and specific software to come the control signal of processes sensor.
Referring to Fig. 2, further, pressure sensor of the present utility model adopts piezoelectric force transducer, and it can measure 10
-3N to 10
4Power in the KN scope, piezoelectric is lead zirconate titanate (PZT).During normal driving, the pressure that chaufeur is acted on the bearing circle is set at a standard value, when the chaufeur one hand is held bearing circle use phone, chaufeur is applied to power on the bearing circle less than this standard value, when detecting pressure for a long time less than this standard value, the vehicle computer judges that driver drives vehicle uses telephone bill to hold bearing circle, and vehicle is in the dangerous driving state, send audio alert by Micro Controller Unit (MCU) driving audio alert chip, the prompting chaufeur stops to use phone in the driving.
Referring to Fig. 3, further, alarm chip of the present utility model adopts Beijing core sound exhibition to open up the PM5020 speech chip that the electronics technology Co., Ltd is produced, its can be real-time the processing of exporting of reception information process unit after control signal, and send corresponding voice suggestion by the loudspeaker that drive this unit.The k1 of PM5020 speech chip, k2,01 mouthful of P3.2 with the 89C52 micro controller system, P3.1, the P3.0 mouth links to each other.The PM5020 speech chip is controlled 0.5 watt of loudspeaker work in 8 Europe by SPI mouth control aerotron 8050.
