Description
Technical field
The utility model relates to a kind of automatic detection and control device, particularly a kind of vehicle-mounted alcohol detecting device.
Background technology
Along with economic development, the vehicle that moves on the road is more and more, yet every year is of common occurrence because of the traffic accident that the chaufeur drunken driving occurs.State's laws regulation blood alcohol content surpasses 0.3mg/ml person and forbids that steering vehicle sets out on a journey, and alcohol content tester is exactly to be used for detecting a kind of instrument that whether alcohol content exceeds standard in the chaufeur blood by the traffic police.But such instrument has a shortcoming is exactly but that the objective for implementation scope is too little, and the traffic police can not hold instrument the rolling stock on the road is detected, and the drunken drivers who is not detected so still very likely causes traffic accident.
The utility model content
Technical problem to be solved in the utility model, the deficiency at the alcohol content tester in the above-mentioned background technology proposes the wider vehicle-mounted alcohol detecting device of a kind of range of use exactly.
The technical scheme in the invention for solving the above technical problem is that a kind of vehicle-mounted alcohol detecting device comprises microprocessor, alcoholic strength detecting sensor, amplifying circuit, Vehicular accumulator cell, annunciator, time delay circuit, automobile starting high-tension coil, switching valve; Described alcoholic strength detecting sensor is connected with amplifying circuit; Described amplifying circuit is connected with microprocessor; Described Vehicular accumulator cell is connected with microprocessor; Described automobile starting high-tension coil is connected with Vehicular accumulator cell by switching valve; Described switching valve is connected with microprocessor; Described time delay circuit is connected with microprocessor with annunciator.
Described switching valve is a crystal triode.
Described annunciator is a buzzer phone.
The utility model beneficial effect is, and is because this device directly is configured on the automobile, so all plays restriction to drunken driving, easy to use and in extensive range.
Description of drawings
Fig. 1 is the block diagram of the utility model embodiment.
T1 is a crystal triode among the figure
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Embodiment:
As shown in Figure 1, this detecting device comprises, microprocessor, alcoholic strength detecting sensor, amplifying circuit, Vehicular accumulator cell, buzzer phone, time delay circuit, automobile starting high-tension coil, crystal triode T1; Described alcoholic strength detecting sensor is connected with amplifying circuit; Described amplifying circuit is connected with microprocessor; Described Vehicular accumulator cell is connected with microprocessor; Described automobile starting high-tension coil is connected with Vehicular accumulator cell by crystal triode T1; Described crystal triode T1 is connected with microprocessor; Described time delay circuit is connected with microprocessor with buzzer phone.Vehicular accumulator cell in the utility model is whole device power supply.
When the chaufeur desire drove to drive, the alcoholic strength detecting sensor can detect the alcohol content of chaufeur.Because detected weak output signal, need to amplify through amplifier, enter microprocessor through amplifying signal, this moment, microprocessor will be judged according to alcohol content in the detected blood of alcoholic strength detecting sensor: (1) is if alcohol content is less than 0.3mg/ml in the blood, combined aural and visual alarm and time delay circuit are not worked, crystal triode T1 conducting Control of Automobile high-tension coil gets electric, and at this moment automobile can start; (2) if alcohol content is more than or equal to 0.3mg/ml in the blood, time delay circuit is started working, time can be set at 10 minutes, buzzer phone begins to send warning simultaneously, time will continue 10 minutes, and microprocessor control crystal triode T1 disconnects, and the automobile starting high-tension coil can not get, automobile can't start like this, time remaining 10 minutes.Coil gets electricly after 10 minutes, at this moment enters again and judges the alcohol content program, and so circulation adopts this device just can stop the drunken driving phenomenon, minimizing traffic accident incidence.
Claims (3)
1. a vehicle-mounted alcohol detecting device comprises alcoholic strength detecting sensor, Vehicular accumulator cell, automobile starting high-tension coil, it is characterized in that, also comprises microprocessor, amplifying circuit, time delay circuit, annunciator, switching valve; Described alcoholic strength detecting sensor is connected with amplifying circuit; Described amplifying circuit is connected with microprocessor; Described Vehicular accumulator cell is connected with microprocessor; Described automobile starting high-tension coil is connected with Vehicular accumulator cell by switching valve; Described switching valve is connected with microprocessor; Described time delay circuit is connected with microprocessor with annunciator.
