Abstract
The utility model discloses a drink-driving preventive device which comprises three pressure sensors and an ethanol sensor. The three pressure sensors are respectively installed below a steering wheel, below an accelerator pedal and below a clutch pedal. The ethanol sensor is installed above the steering wheel. The three pressure sensors and the ethanol sensor are all connected to an input end of a single chip microcomputer (SCM). An output end of the SCM is further connected with a buzzer and a steering wheel self-lock device. The drink-driving preventive device is simple in structure and easy to achieve. Data information of drink-driving can also be recorded through a storer additionally arranged on the SCM so as to provide strong data support for duty partition and allocation of future drink-driving accidents. A wireless transceiver can also be further configured, and when a drink-driving vehicle enters a working area of the wireless transceiver of a traffic police, the vehicle sends a message to the traffic police so as to inform the traffic police of the drink-driving vehicle nearby. Thus, the drink-driving can be effectively controlled.
Description
Technical field
The utility model relates to the auxiliary intellectual monitoring of a kind of automobile and protection system, is specifically related to a kind of drunk driving prevention device.
Background technology
Drink-driving at present is to become the hidden danger that affects the safety traffic maximum.Traffic accident more than 60% is all because drink-driving is caused, and drink-driving not only causes traffic accident, endangers public security, and sometimes also can give oneself, and other people cause serious life harm.At present, the phenomenon ubiquity of China's drink-driving, only rely on fine detention can not fundamentally limit drink-driving, but, there is no reasonable actv. measure to stop for drink-driving at present, cause some car owner's disregard of law regulation, the drink-driving of making a desperate move, finally lead to the catastrophe of car crash.Yet, there is no at present the device of special restriction drink-driving, therefore, necessary drink-driving is prevented and restriction, thereby, to oneself, other people are useful with society.
Summary of the invention
For defect of the prior art or deficiency, the purpose of this utility model is, a kind of drunk driving prevention device is provided.
For realizing above-mentioned technical assignment, the utility model is taked following technical solution:
A kind of drunk driving prevention device, it is characterized in that, comprise three pressure sensors and an alcohol sensor, three pressure sensors wherein are arranged on respectively bearing circle below, Das Gaspedal below and pedal of clutch below, alcohol sensor is arranged on the bearing circle top, three pressure sensors and alcohol sensor all are connected in the input end of micro controller system, also are connected with buzzer phone and bearing circle self-locking device on the mouth of micro controller system.
Other characteristics of the present utility model are:
Described pressure sensor is selected the HK-610G pressure sensor, and alcohol sensor is selected the MQ-3 ethanol sensor.
Described micro controller system adopts the MC9S12XS128 micro controller system.
Described three pressure sensor models are identical.
Drunk driving prevention device of the present utility model, utilization is arranged on the alcohol sensor of vehicle steering top, alcohol content in the chaufeur breath is detected, chaufeur is held to the power of bearing circle with three pressure sensors simultaneously, clutch-pedal load, Das Gaspedal power detects in real time, the data that each period collects are directly sent into to main control unit, in micro controller system, data during by the chaufeur normal driving stored in collected data and micro controller system compare, and then can judge the whether drink-driving of this chaufeur.If drink-driving, send chimes of doom by the Single-chip Controlling buzzer phone, remind chaufeur to stop at once, the bearing circle self-locking device is automatically locked simultaneously, thereby tries to forestall traffic accidents generation.This device is simple and practical, can effectively prevent the chaufeur drink-driving, thereby can directly reduce the traffic accident caused by drink-driving.Apparatus structure is simple, is easy to realize.But also can be by the memory device increased on micro controller system, the data message during by drink-driving is recorded, for later drink-driving accident liability defines, divides the Data support that provides strong.Also can further be equipped with wireless transmitting-receiving equipments, when having the drink-driving vehicle to enter in traffic police's wireless transmitting-receiving equipments work area, vehicle just sends information to the traffic police, and inform near the traffic police drink-driving automobile is arranged, like this, can actv. containment drink-driving.
The accompanying drawing explanation
Fig. 1 is structured flowchart of the present utility model.
Below in conjunction with the specific embodiment, the utility model is further explained.
The specific embodiment
Referring to Fig. 1, the present embodiment provides a kind of physical circuit block diagram of drunk driving prevention device, comprise three pressure sensors and an alcohol sensor, three pressure sensors wherein are arranged on respectively bearing circle below, Das Gaspedal below and pedal of clutch below, alcohol sensor is arranged on the bearing circle top, three pressure sensors and alcohol sensor all are connected in the input end of micro controller system, also are connected with buzzer phone and bearing circle self-locking device on the mouth of micro controller system.
In the present embodiment, pressure sensor is selected the HK-610G pressure sensor, and alcohol sensor is selected the MQ-3 ethanol sensor, and micro controller system adopts the MC9S12XS128 micro controller system, also is connected with memory device on micro controller system.
The cardinal principle of device is, the alcohol sensor that is arranged on the bearing circle top is detected the alcohol amount in the chaufeur breath, with three HK-610G pressure sensors, be arranged on below bearing circle below, pedal of clutch below and Das Gaspedal simultaneously, chaufeur is acted on to bearing circle, pedal of clutch, the power on Das Gaspedal is measured and is added up.As long as chaufeur is connected ignition lock, will connect MQ-3 ethanol sensor and HK-610G pressure sensor circuit, MQ-3 ethanol sensor and the work of HK-610G pressure sensor, disconnect ignition lock, now, MQ-3 ethanol sensor and HK-610G pressure sensor circuit disconnect and quit work.
Chaufeur is connected ignition lock, start Vehicle Driving Cycle, the HK-610G pressure sensor will be recorded navigating mate and act on bearing circle, pedal of clutch, power on Das Gaspedal, the MQ-3 ethanol sensor detects in real time to the alcohol amount in the chaufeur breath simultaneously.This device adopts three pressure sensors that model is identical, be separately positioned on bearing circle, pedal of clutch, the Das Gaspedal below, while arranging, window is 1.2s, data in solid timing window size are carried out to correlation analysis, gain knowledge and easily know according to psychology physiological, brain nervous centralis paralysis when chaufeur is drunk, reflection is slow, and the brain command function reduces, be in particular on the fluctuation size of data, therefore, grip to the bearing circle in solid timing window, brake pedal force and Das Gaspedal power are carried out correlation analysis, get in twos covariance, data by resulting data during with the chaufeur normal driving are compared, if be greater than threshold value δ
0the MQ-3 ethanol sensor detects in real time to the alcohol amount in the chaufeur breath simultaneously, when in the chaufeur breath, alcohol content exceeds set numerical value, the Single-chip Controlling buzzer phone sends chimes of doom, controls the bearing circle automatic locking device simultaneously and makes bearing circle locked.
Certainly, can also be by the memory device increased on micro controller system, the data logging during by drink-driving is got off, for drink-driving responsibility judgment, division later provides strong Data support.Also can further be equipped with wireless transmitting-receiving equipments, when having the drink-driving vehicle to enter in traffic police's wireless transmitting-receiving equipments work area, vehicle just sends information to the traffic police, and inform near the traffic police chaufeur drink-driving is arranged, like this, can actv. containment drink-driving.
