Abstract
The utility model relates to a device for an automobile, in particularly to an automobile drunk driving limiter. The automobile drunk driving limiter is characterized in that a gas collector and an alcohol detector are arranged in a cab, wherein switches of the gas collector and the alcohol detector are arranged on an automobile door and a start keyhole on one side of the cab; and the alcohol detector is connected with an automobile circuit control relay. The automobile drunk driving limiter has the beneficial effects that when a driver enters into the automobile, the gas collector and the alcohol detector immediately get to work and gas nearby is collected and detected; when the alcohol detection concentration exceeds a set value, the rely gets to act and an automobile circuit is cut off, so as to enable the automobile to be automatically flamed out; and if the alcohol detection concentration does not exceed the set value, the automobile is normally started. Thus drunk driving can be actively limited and accident potential is exterminated before occurrence.
Description
Technical field
The utility model relates to a kind of Vehicular device, promptly a kind of automobile drunk driving killer.
Background technology
Drunk driving is the one of the main reasons that causes traffic accident, and at present, relevant department takes effective measures, and cross-check sum is carried out in the drunk behavior of driving punish., above-mentioned measure can only could be implemented in the drunk driving process, is difficult to prevent drunk driving behavior and drunk driving accident.Find to adopt the measure of punishing also to have passive social influence after the drunk driving behavior.Therefore, people hope to have a kind of alcohol content in can active monitoring navigating mate body, and the device of restriction drink-driving behavior.
Summary of the invention
The purpose of the utility model provides a kind ofly can in time be found in the chaufeur body overproofly, and stops the automobile drunk driving killer of vehicle launch function.
Above-mentioned purpose is realized by following technical scheme: develop a kind of automobile drunk driving killer; Be characterized in: in operator's compartment, be provided with gas collecting device and alcohol detector; The switch of gas collecting device and alcohol detector be located on the car door of operator's compartment one side with automobile starting switch key mouth on, alcohol detector and vehicle circuit control relay interrelate.
Said gas collecting device is provided with the negative pressure bleed ports, and the negative pressure bleed ports is located in the center and automobile starting key hole of bearing circle.
The switch of said gas collecting device and alcohol detector is univibrator and IGCT.
Said univibrator is made up of 555 time meters and peripheral resistance R capacitor C.
Said alcohol detector is provided with alcohol gas sensor QM-NJ9; Alcohol gas sensor QM-NJ9 is provided with gas sensing resistance and potential device RP1, and interrelates with high power switch IC1, speech IC IC2, integrated amplifier IC circuit 3 and automobile circuit control relay J1.
Said high power switch IC1 adopts integrated package TWH8778.
Said speech IC IC2 adopts integrated package TM801.
Said integrated amplifier IC circuit 3 adopts integrated package LM186.
The beneficial effect of the utility model is: when chaufeur into the car; Gas collecting device and alcohol detector commence work without delay, and collect gas nearby and detect, when alcohol detection concentration surpasses setting value; The actuating of relay is cut off automobile circuit and is made the automobile auto shut down.Do not surpass setting value, automobile normally starts.Thereby can initiatively limit drink-driving, accident potential was eliminated before taking place.
Description of drawings
Fig. 1 is the structured flowchart of a kind of embodiment;
Fig. 2 is the circuit diagram of this embodiment.
Visible among the figure:
The specific embodiment
Total design of the utility model is in car, to install to carry out the alcohol concentration detection to the breathing gas of chaufeur, when concentration over-standard, cuts off the device of motor start circuit.Introduce a kind of embodiment below in conjunction with accompanying drawing:
As shown in Figure 1, on automobile starting switch, be connected to a univibrator and an electronic switch IGCT, the electronic switch IGCT is connected to gas collecting device and alcohol concentration at the back by surveying device, and the alcohol concentration detector connects the automobile circuit control relay.
Fig. 2 has introduced a circuit diagram.Visible by figure, univibrator is to be made up of one 555 time meter and peripheral resistance R, capacitor C, and its mouth VT meets IGCT V.The switch of univibrator is located in the car door and automobile starting key hole of operator's compartment one side, and entering is perhaps inserted key and started jack and rotation as long as chaufeur opens the door, and binary pair will be started working.The gas collecting device here is provided with the negative pressure bleed ports, and the negative pressure bleed ports is located at the center and the key hole inboard of bearing circle.The negative pressure bleed ports connects the alcohol concentration detector through pipeline; The core component of alcohol concentration detector is one and meets alcohol gas sensor QM-NJ9; Alcohol gas sensor QM-NJ9 is a kind of gas sensing resistance that interrelates with potential device RP1, and the back is connected to high power switch IC1, speech IC IC2, integrated amplifier IC3 and relay J 1.Wherein, high power switch IC1 can adopt TWH8778 integrated package, speech IC IC2 can adopt TM801 integrated package, integrated amplifier IC3 can adopt the LM186 integrated package.Resistance between the gas sensing resistance A-B of QM-NJ9 then when accepting the alcohol smell, the sliding end current potential of potential device RP1 raises.When this current potential was elevated to 1.6V, high power switch IC1 connected, and made speech IC IC2 work, and its output promotes loud speaker BL18 and sends chimes of doom after integrated amplifier IC3 carries out power gain.Simultaneously, relay J 1 gets electronic work, and contact open cuts off automobile igniting circuit, forces engine off, reaches the purpose that the control driver drivings a car under the influence of alcohol.If do not detect the alcohol smell, the automobile normal operation.
