Abstract
The utility model discloses an automatic automobile-mounted alcohol detecting device which comprises a control box, a gas sensor, a digital-to-analog conversion module, a control unit, a normally open relay and a buzzer, wherein the gas sensor is installed on a lower surface of a sun shield above a head of a driver, and other components are packaged in the control box which is installed below a center console in a cab; a signal output end of the gas sensor is connected with an input end of the digital-to-analog conversion module, and an output end of the digital-to-analog conversion module is connected with an input end of the control unit; and the normally open relay and the buzzer are respectively connected with an output port of the control unit, and a control end of the normally open relay is connected with a starting circuit of an automobile engine. By using the device, gas exhaled by each driver can be stably and effectively measured, if the breathing alcohol content of the driver exceeds the national limit value, an automobile can be prevented from being started, and the drunk driver is technically prohibited from driving.
Description
Technical field
The utility model belongs to the process control field, relates to a kind of alcohol detecting device, is specifically related to a kind of intelligent vehicle-carried alcohol detecting device.
Background technology
In recent years, the traffic accident that drunken driving causes is more and more, become the primary factor of traffic accident, though national correlation department has been promulgated a series of laws and regulations to drunken driving, but mostly be traffic constable enforcement owing to detect the behavior of chaufeur drunken driving at present, this has just caused the scrutiny program complexity, and randomness is stronger, can not guarantee that each chaufeur can both accept detection, can make that finally having lucky chaufeur at heart still drives when intoxicated.Existing hand-held alcohol content tester can only rely on artificial could the detection chaufeur, the relatively waste of manpower of this mode.
Therefore, at the shortcoming that the hand-held alcohol content tester can't carry out alcohol screen test to each chaufeur, designing a kind of automatic vehicle-mounted alcohol detecting device is very to be necessary.
Summary of the invention
At above-mentioned defective of the prior art or deficiency, the purpose of this utility model is, a kind of automatic vehicle-mounted alcohol detecting device is provided, this device can be stablized the gas of effectively each chaufeur being breathed out and measure, when if the breath alcohol content of chaufeur surpasses national limit value, can stop automobile starting, the chaufeur after forbidding technically drinking is driven.
For realizing above-mentioned technical assignment, the utility model is taked following technical solution:
A kind of automatic vehicle-mounted alcohol detecting device comprises control capsule, gas sensor, D/A converter module, control unit, normally opened relay and buzzer phone.Wherein, described gas sensor is installed in the sun shield lower surface of chaufeur above-head, and all the other each component packages are in control capsule, and described control capsule is placed in the console below of automobile cab; Wherein, the signal output part of described gas sensor connects the input end of D/A converter module, and the mouth of D/A converter module connects the input end of control unit, and normally opened relay, buzzer phone are connected with the delivery port of control unit respectively; The control end of normally opened relay connects the automobile engine starting circuit.
Further, described control unit adopts STA89C51 type micro controller system; Described gas sensor adopts MQ-3 type gas sensor; Described D/A converter module adopts ADC0809.
Compare with the existing alcohol detecting device in market, advantage of the present utility model is;
MQ-3 type detection sensitivity height in the utility model, output signal are the volt level; Speed of response was less than 10 seconds.Therefore, the utility model can be stablized effectively the gas that chaufeur is breathed out and measures, if when gaseous alcohol content surpasses national standard, starts buzzer phone and also stops automobile starting, has guaranteed the safety of chaufeur and highway communication.
Principle of design of the present utility model is as follows:
Intelligent vehicle-carried alcohol detecting device of the present utility model, when chaufeur rotates the startup key to ON, the checking system energising, the control unit initialization, the gas sensor preheating, control unit sends the minor alarm command one time to buzzer phone behind the 20s, and the prompting chaufeur is done breathing gas and is detected.When the chaufeur alcoholicity of exhaled gas surpasses national regulation, control unit sends to buzzer phone and continues the long instruction, but does not send instruction to relay, stops engine starting.When the chaufeur alcoholicity of exhaled gas surpasses national regulation, control unit does not send instruction to buzzer phone, but sends instruction to relay, relay closes, and start-up circuit is connected, and driving engine normally starts.
Description of drawings
Fig. 1 is structured flowchart of the present utility model.
Below in conjunction with the drawings and specific embodiments the utility model is further explained.
The specific embodiment
As shown in Figure 1, automatic vehicle-mounted alcohol detecting device of the present utility model comprises control capsule, gas sensor, D/A converter module, control unit, normally opened relay and buzzer phone.Wherein, described gas sensor is installed in the sun shield lower surface of chaufeur above-head, and all the other each component packages are in control capsule, and described control capsule is placed in the console below of automobile cab; Wherein, the signal output part of described gas sensor connects the input end of D/A converter module, and the mouth of D/A converter module connects the input end of control unit, and normally opened relay, buzzer phone are connected with the delivery port of control unit respectively; The control end of normally opened relay connects the automobile engine starting circuit.
In the present embodiment, the product of above-mentioned each parts is selected as follows: control unit adopts STA89C51 type micro controller system; Gas sensor adopts MQ-3 type gas sensor, and its operating voltage is 5V; D/A converter module adopts ADC0809; Normally opened relay and buzzer phone operating voltage are 5V.
Working process of the present utility model is as follows:
The utility model is applied to general-utility car, is mainly used in cutting off in the case of necessary start-up circuit, stops engine starting.
When starting switch is in the ON position, gas sensor, digital-to-analogue converter and control unit energising, gas sensor preheating, D and A converter and control unit initialization.Behind the 20s, control unit sends the minor alarm command one time to buzzer phone, the detection of exhaling of buzzer phone prompting chaufeur.When the chaufeur alcoholicity of exhaled gas surpasses national regulation, control unit sends to buzzer phone and continues the long instruction, but does not send instruction to normally opened relay.Therefore, the engine starting circuit breaker, driving engine can not start.
When the chaufeur alcoholicity of exhaled gas surpasses national regulation, control unit sends instruction to relay, but does not send instruction to buzzer phone.Behind the relay power, the normal open switch closure, the engine starting circuit pathways, driving engine normally starts.
Because carrying out the chaufeur alcoholicity of exhaled gas in operator's compartment, the utility model device detects, so in order to reach national limit value, should improve the sensitivity of gas sensor.
