Abstract

The invention relates to the alcohol detection technology, and provides an on-board alcohol detector comprising an alcohol sensor, a wind velocity sensor and a humidity and temperature sensor. The alcohol sensor is connected with a first amplifier circuit, a first analog-to-digital conversion circuit and a microprocessor through a signal wire sequentially. The wind velocity sensor is connected with a second amplifier circuit, a second analog to digital conversion circuit and the microprocessor through a signal wire sequentially. The humidity and temperature sensor is connected with a third amplifier circuit, a third analog to digital conversion circuit and the microprocessor through a signal wire sequentially. The microprocessor is respectively connected to a matrix keyboard, a buzzer and a relay through a signal wire, and the relay is connected to an ignition switch outgoing line of a vehicle through a signal wire. The on-board alcohol detector is convenient to use, and has functions of alarming, voice prompting and forced flameout. Alcohol content exceeding the threshold can be set flexibly and conveniently through the keyboard, while the alcohol content can be displayed on an LED display screen in real time clearly and visually.

Description

A kind of vehicle-mounted alcohol detection apparatus
Technical field
The present invention relates to alcohol detection technology, especially a kind of vehicle-mounted alcohol detection apparatus.
Background technology
Along with expanding economy, the use amount of automobile is more and more, but because of the drive when intoxicated accident that causes of chaufeur also increasing.Renovate drunk driving, not only relate to motorist's self safety, be related to especially the major issue that concerns of people's life security.Existing alcohol detecting device be take hand-held type of respiration as main, and a lot of chaufeurs are reluctant often to carry alcohol detecting device, and often there is idea of leaving things to chance, after drinking, still attempt to drive, cause alcohol detecting device use inconvenient and can not monitor in real time alcohol content in car, have very large potential safety hazard.
Summary of the invention
The technical problem to be solved in the present invention is, overcomes and in prior art, uses inconvenient and can not monitor in real time the deficiency of alcohol content in car, and a kind of vehicle-mounted alcohol detection apparatus is provided.
For technical solution problem, solution of the present invention is:
The invention provides a kind of vehicle-mounted alcohol detection apparatus, comprise alcohol sensor; Alcohol sensor connects the first amplifying circuit, the first analog to digital conversion circuit (A/D change-over circuit) and microprocessor (MCU) successively by signal wire (SW), air velocity transducer connects the second amplifying circuit, the second analog to digital conversion circuit and microprocessor successively by signal wire (SW), and Temperature Humidity Sensor connects the 3rd amplifying circuit, the 3rd analog to digital conversion circuit and microprocessor successively by signal wire (SW); Microprocessor is also connected to respectively matrix keyboard, buzzer phone and relay by signal wire (SW), and relay is connected to the ignition lock pig-tail wire of vehicle by signal wire (SW).In this device, whether air velocity transducer and Temperature Humidity Sensor are used for detecting chaufeur and blow, and matrix keyboard is used for arranging threshold value and the unlatching vehicle-mounted alcohol detection apparatus that alcohol content exceeds standard; When alcohol content being detected when too high, buzzer phone is used for reporting to the police, and the ignition lock circuit of Control is controlled ignition lock to control actuating motor and the igniting of automobile.
As a kind of improvement, described microprocessor is connected with LCD LCDs by signal wire (SW), is used for showing the alcohol concentration of surveying.
As a kind of improvement, described microprocessor is connected with voice module by signal wire (SW), and voice module is used for pointing out chaufeur.
As a kind of improvement, described microprocessor is connected with the Fuel path lock of being located on vehicle oil feed line by signal wire (SW), cuts off vehicle oil feeding line when alcohol content exceeds standard.
As a kind of improvement, described alcohol sensor is arranged on the bearing circle of operator's compartment, facilitates chaufeur to blow, and from chaufeur close to, in the way of travelling, can detect more accurately airborne alcohol content.
With respect to prior art, the invention has the beneficial effects as follows:
(1) easy to use: chaufeur does not need to carry alcohol detecting device, when getting on the bus, can detect alcohol content by air blowing and whether exceed standard; In the way of travelling, can prevent that chaufeur from drinking on the way by the airborne alcohol content of Real-Time Monitoring.
(2), while alcohol content being detected exceed standard when getting on the bus, can report to the police and voice message; When alcohol content being detected exceeding standard in way, can report to the police and voice message chaufeur stops, otherwise automobile will be forced to stop working in the near future;
(3) threshold value that can exceed standard by keyboard to set up alcohol content, flexible and convenient to use.
(4) when car enforce is flame-out, the loop of while point of cutoff fire coil and actuating motor.
(5) can on LCD display, show alcohol content in real time, clear directly perceived.
Accompanying drawing explanation
Fig. 1 is the structural representation of patent of the present invention.
Reference numeral in figure:
Alcohol sensor 1, the first amplifying circuit 2, the first analog to digital conversion circuit 3, microprocessor 4, logical the 5, second amplifying circuit 6 of air velocity transducer, the second analog to digital conversion circuit 7, Temperature Humidity Sensor 8, the 3rd amplifying circuit 9, the 3rd analog to digital conversion circuit 10, matrix keyboard 11, buzzer phone 12 and relay 13, LCD LCDs 14, voice module 15, Fuel path lock 16.
The specific embodiment
Vehicle-mounted alcohol detection apparatus in the present invention, has following structure:
Alcohol sensor 1 connects the first amplifying circuit 2, the first analog to digital conversion circuit 3 and microprocessor 4 successively by signal wire (SW), air velocity transducer 5 connects the second amplifying circuit 6, the second analog to digital conversion circuit 7 and microprocessor 4 successively by signal wire (SW), and Temperature Humidity Sensor 8 connects the 3rd amplifying circuit 9, the 3rd analog to digital conversion circuit 10 and microprocessor 4 successively by signal wire (SW); Microprocessor 4 is also connected to respectively matrix keyboard 11, buzzer phone 12, relay 13, LCD LCDs 14, voice module 15 and Fuel path lock 16 by signal wire (SW), and relay 13 is connected to the ignition lock pig-tail wire of vehicle by signal wire (SW).
The using method of vehicle-mounted alcohol detection apparatus:
When chaufeur is got on the bus, press the start button of matrix keyboard 11, open alcohol detecting device, now can adjust the threshold value that alcohol content exceeds standard by matrix keyboard 11; Facing to alcohol detecting device, blew for three seconds, by the detection of air velocity transducer 5 and Temperature Humidity Sensor 8, on LCD display, can show alcohol content, if exceed standard, can report to the police and voice message.
Automobile is in the way of travelling, and alcohol detecting device can detect alcohol content in air automatically, when alcohol content exceeds standard in air, reminds chaufeur stop at once and report to the police, otherwise after certain hour, stops engine ignition and actuating motor loop, automobile flameout.
