Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1 to Figure 3, the automobile anti-drunken driving control system of the present embodiment comprises ignition lock 10, sensor 20, control module 30, safety switch 40, battery 50 and starter motor 60.Described ignition lock 10, for starting automobile, under normal circumstances, is inserted in ignition lock 10 can be started automobile by key 70.Described sensor 20 is the sensors for detecting alcohol, and it comprises main body 21 and detection head 22, and detection head 22 is positioned at main body 21 end, and alcohol enters sensor by detection head 22.Described sensor 20 can be tin ash sensor, and it comprises a pair pole piece 11, load resistor 12 and tungsten filament 13, and described load resistor 12 is connected with the mouth of sensor 20.When sensor 20 runs into alcohol, the resistance value of sensor can change, thus measures alcohol concentration.Described sensor 20 can be arranged near instrument desk, thus makes detection head 22 can near chaufeur position.Described control module 30 is connected with sensor 20, and it is for the judgement to alcohol concentration.Described control module 30 is connected with safety switch 40 and starter motor 60 respectively.Described safety switch 40 is for control circuit break-make, and the control of its controlled module 30, safety switch 40 can be electromagnetic switch.Safety switch 40 is connected with battery 50 and ignition lock 10 respectively.Described battery 50 is for providing electric power for anti-drunk drive control system, and described starter motor 60 for driving automobile engine running, thus enables automobile start.Described control module 30 also comprises display equipment 80, and it is for showing alcohol concentration, thus reminds chaufeur and passenger inside the vehicle to stop in time driving a car.
As shown in Figure 3 and Figure 4, described control module 30 comprises op amp 200 (being called for short " amplifier 200 "), analog-digital converter 300, microcontroller 400, direct current transducer 500 and adaptor union 600.Described amplifier 200 is connected with sensor 20, amplifies for the signal sent by sensor.Described analog-digital converter 300 is connected with amplifier 200, can convert described signal to digital signal.Described microcontroller 400 is connected with analog-digital converter 300, and it carries out related operation according to digital signal.Described direct current transducer 500 is connected with amplifier 200, analog-digital converter 300 and microcontroller 400 respectively, thus converts the higher vdc of battery 50 vdc of the spendable 2V to 5V of above-mentioned electronic devices and components to.Described adaptor union 600 is connected with direct current transducer 500 respectively, and adaptor union 60 can be the power taking interface on automobile, thus makes control module 30 obtain electric energy.Further, described control module 30 comprises memory cell 45, and memory cell 45 is connected with microcontroller 40, for storing information.Those skilled in the art are known, and memory cell 45 also can be integrated in microcontroller 40.
When chaufeur key 70 inserted key hole and rotate key perform igniting time, because safety switch 40 is in normally open, therefore battery 50 cannot provide igniting required electric energy; Therefore force chaufeur must pass through the detection of sensor 20, when alcohol detection value is no more than preset value, control module 30 will close safety switch 40, thus automobile is started.When alcohol concentration exceedes preset value, display equipment 80 will show alcohol concentration, to remind chaufeur and passenger, ignition system is in open-circuit condition, makes chaufeur start vehicle.
It is to be noted; above-mentioned preferred embodiment is only and technical conceive of the present utility model and feature is described; its object is to person skilled in the art can be understood content of the present utility model and implement according to this, protection domain of the present utility model can not be limited with this.All equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed within protection domain of the present utility model.
