Abstract
The utility model discloses a drink identification and starting device based on a singlechip, which comprises a detection unit, a conversion unit, an information processing unit, an early warning unit and a power supply, wherein the detection unit, the conversion unit, the information processing unit and the early warning unit are sequentially connected, and the power supply is connected with the information processing unit. The device has high sensitivity and response speed, is accurate, efficient and high in intelligence, and can detect alcoholic strength of a drunk driver before and after driving; when the alcoholic strength is out of a limit, an early warning measure is taken or the power supply is cut off immediately to compel the driver to give up the driving, so that the drunk driving is reduced; and life safety and property safety of the driver are protected.
Description
Technical field
The utility model belongs to the automotive safety technical field, relates in particular to a kind of SCM Based identification starter gear of drinking.
Background technology
Along with the develop rapidly of economy, the Chinese automobile recoverable amount increases year by year, and automobile is the most common in people's daily life, and the most general is also one of the highest vehicle of frequency of utilization.Automobile has irreplaceable effect as the important vehicle of the mankind in people's daily life, due to the impact of the factors such as artificial, vehicle, road traffic environment, car accedent is more and more, and Minor Accident emerges in an endless stream, and serious accident also occurs often.Show only have 20% surveyee to have no precedent the behavior of driving when intoxicated according to certain website investigation.Overwhelming majority people have gained some understanding for the harm of driving when intoxicated, but under relatives and friends " great kindness " persuades, often will covet drink and drive to go home after several glasss again.Investigation shows, 40% drunken driving " driving technique of oneself is believed on the highland excessively ", and not recognizing drives when intoxicated can cause very large potential safety hazard, tends to cause too late to regret traffic accident.So, which harm does driving when intoxicated have on earth? show according to accident investigation, about 50%～60% traffic accident is all relevant with drunken driving, and drunken driving has been listed in the lethal major cause of traffic accident.
Summary of the invention
The purpose of this utility model is, a kind of SCM Based identification starter gear of drinking is provided, and whether this device can detect in real time chaufeur and drink, and according to what of drinking amount, determines whether to report to the police and cut off automobile power source, prevents the generation of drunk driving event.
In order to realize above-mentioned task, the utility model adopts following technical scheme to be achieved:
A kind of SCM Based identification starter gear of drinking, comprise detecting unit, converting unit, information process unit, prewarning unit and power supply, wherein, detecting unit, converting unit, information process unit are connected with prewarning unit and are connected, power supply link information processing unit.
The utility model also has following other technologies characteristics:
Described detecting unit comprises temperature sensor, heating arrangement and is connected a gas sensor that connects side by side, and described gas sensor, temperature sensor and heating arrangement are connected with information process unit and are connected; Described gas sensor is the tin ash semiconductor transducer, and described temperature sensor adopts the PT100 sensor.
Described converting unit comprises signal amplification circuit and the TLC2543 pattern number converter that connects successively.
Described information process unit adopts the Atmel89C52 micro controller system.
Described prewarning unit comprises LED lamp and automobile supply line, and described LED lamp and automobile supply line be the link information processing unit respectively.
Described power acquisition circuit of three-terminal voltage-stabilizing integrated LM7805.
This device sensitivity is high, and speed of response is fast, and accurate, efficient and intelligent degree is high.Can be to the chaufeur of having drunk before driving and detect the alcoholic strength of chaufeur in driving; immediately take Forewarning Measures or cut off power supply as long as alcoholic strength exceeds standard; force chaufeur to abandon continuing driving intention, thereby reduce the generation of drunk driving, the safety of life and property of protection navigating mate.This device is applied widely, and cost is low, and is convenient and practical, provides good support for safeguarding order of traffic.
Description of drawings
Fig. 1 is structure connection diagram of the present utility model.
Fig. 2 is the utility model workflow diagram.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details.
The specific embodiment
Fig. 1 is structure connection diagram of the present utility model, comprises detecting unit, converting unit, information process unit, prewarning unit and power supply.Wherein, detecting unit comprises PT100 temperature sensor, heating arrangement and is connected a tin ash semiconductor gas sensor that connects side by side, and described heating arrangement is the temperature booster of this area routine; Converting unit adopts signal amplification circuit and TLC2543 pattern number converter, and described signal amplification circuit is the signal amplification circuit of this area routine; Information process unit adopts the Atmel89C52 micro controller system, and prewarning unit comprises LED lamp and automobile supply line; Power acquisition circuit of three-terminal voltage-stabilizing integrated LM7805.
The device power supply by circuit of three-terminal voltage-stabilizing integrated LM7805 with the automotive battery loss in voltage most 5V for information process unit.
Detecting unit is arranged on bearing circle, is used for gathering alcohol smell; Detecting unit is to be made of one group of gas sensor, and gas sensor adopts the tin ash quartz conductor, and this based semiconductor device has gas-sensitive property, and its responsive gas concentration increases in the gas of contact, and the resistance value that it externally presents will reduce.In order further to improve sensitieness, described sensor has four, and employing is connected in parallel.
Detecting unit comprises temperature sensor and heating arrangement, and the real time detecting sensor operating temperature when sensor is not to connect heating arrangement when being operated in optimum regime gas sensor is heated, guarantees that sensor carries out work under optimum temperature.
Gas sensor is connected with micro controller system by A and D converter, and the monolithic function is processed the sensor signal through the A and D converter conversion in real time, sends signal through processing the backward prewarning unit of calculating.Calculate through micro controller system, if alcoholic strength during near setting threshold, the early warning LED lamp flicker reminding driver that is positioned on gauge panel is not wanted drinking drive; Cut off the automobile power supply when glimmering by the prewarning unit lightening LED lamp when alcoholic strength meets or exceeds setting threshold, force chaufeur to abandon driving, occur to prevent the drink-driving event.
Workflow of the present utility model is as shown in Figure 2: power to micro controller system after when starting automobile, key turns, program initialization begins to carry out, the gas sensor detection alcohol concentration of starting working, temperature sensor detects the gas sensor operating temperature, the starting heating arrangement makes the alcoholic strength working sensor at optimum temperature range, improves sensitivity.The signal of gas sensor passes to micro controller system after converting digital signal to through TLC2543, and micro controller system is through computing, judge chaufeur whether drinking drive or drink-driving, more logical prewarning unit is reported to the police or directly cuts off the operation that automobile is powered.
