Abstract
The utility model relates to a drunk-driving prohibiting device for an automobile, which comprises an alcohol sensor, a master control MCU (micro-control unit) and a controller. The alcohol sensor is a non-contact type alcohol sensor and is connected to the master control MCU by a signal amplifying processing circuit, the master control MCU is connected with the controller, and the controller is connected onto an ignition device of the automobile. The drunk-driving prohibiting device realizes prohibiting drunk driving and automatically cuts off the ignition device of the automobile when detecting that an automobile driver enters a cab and attempts to drive the automobile after drinking, consequentially, the automobile cannot be started so as to avoid driving after drinking or even being drunk, and accordingly the drunk-driving prohibiting device effectively protects personal and property safety of people and has excellent social benefit and economic benefit.
Description
Technical field
The utility model relates to intellectual technology, specifically relates to a kind of after-drink driving-prohibition automotive fittings.
Background technology
Drink even the driving of drunk back, very easily cause traffic accident,, bring great loss certainly will for people's life and property in case traffic accident takes place.At present the law of China, rules be to drinking even the driving behavior of drunk back has strict restriction, forbids to drink even drive in drunk back, but drink even the behavior driven in drunk back still happens occasionally.At this situation, the market active demand is designed a kind of drunk driving drunk driving and is prohibited opening apparatus, and this device cuts off the ignition device of automobile automatically when detecting the automobile driver and enter operator's compartment after drinking and desire to drive a car, it can not be started, thereby avoid drinking even drunk back situation generation of driving.
Summary of the invention
At the defective that exists in the prior art, the purpose of this utility model provides a kind of after-drink driving-prohibition automotive fittings, after the behavior that this device in case detect is drunk even drive in drunk back, cuts off the ignition device of automobile automatically, and it can not be started.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of after-drink driving-prohibition automotive fittings, comprise alcohol sensor, main control MCU and controller, described alcohol sensor is contactless alcohol sensor, it connects main control MCU by a signal processing circuit, main control MCU connects controller, and controller is connected on the ignition device of automobile.
During use, place vehicle drive indoor the utility model, and connect with the ignition device of automobile, after the automobile driver enters operator's compartment after drinking, contactless alcohol sensor detects the alcohol concentration in the cab space automatically, and alcohol concentration is converted into electric signal feed signals amplification treatment circuit, send main control MCU behind signal processing circuit amplification and the processing alcohol concentration signal, main control MCU is according to the alcohol concentration standard, if alcohol concentration exceeds standard in the gas that navigating mate is breathed out, then indicating controller closing automobile ignition device makes automobile not start.
The beneficial effects of the utility model are: utilize the collaborative work of alcohol sensor, main control MCU, controller etc.; realized a kind of after-drink driving-prohibition automotive fittings; this device is when detecting the automobile driver and enter operator's compartment after drinking and desire to drive a car; automatically cut off the ignition device of automobile; it can not be started; thereby avoid drinking even drunk back situation generation of driving, protected the safety of people's lives and properties effectively, have good social value and economic value.
Description of drawings
Fig. 1 is the utility model principle assumption diagram.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
In Fig. 1, a kind of after-drink driving-prohibition automotive fittings, comprise alcohol sensor 1, main control MCU 3 and controller 4, described alcohol sensor 1 is contactless alcohol sensor, it connects main control MCU 3 by a signal processing circuit 2, main control MCU 3 connects controller 4, and controller 4 is connected on the ignition device 5 of automobile.
During use, place vehicle drive indoor the utility model, and connect with the ignition device of automobile, after the automobile driver enters operator's compartment after drinking, contactless alcohol sensor 1 detects the alcohol concentration in the cab space automatically, and alcohol concentration is converted into electric signal feed signals amplification treatment circuit 2, send main control MCU 3 behind signal processing circuit 2 amplifications and the processing alcohol concentration signal, main control MCU 3 is according to the alcohol concentration standard, if alcohol concentration exceeds standard in the gas that navigating mate is breathed out, then indicating controller 4 closing automobile ignition devices 5 make automobile not start.
