Description
Technical field
The utility model relates to a kind of suggestion device, relates in particular to a kind of alarming device of pointing out drunk driving to external world.
Technical background
Along with rapid development of economy, automobile rapidly increases as the important vehicle of the mankind, and simultaneously owing to factor affecting such as artificial, road, friendship rule, car accedent is more and more, and Minor Accident emerges in an endless stream, and serious accident also takes place often.Show that according to accident investigation about 50%～60% traffic accident is all relevant with drunken driving, drunken driving has been classified as the major cause that traffic accident causes death." Criminal Law of the People's Republic of China amendment (eight) " will implement, and drunk driving and joyride are gone into punishment and determined a crime, and can find out the attention of country to drunk driving.
Thereby this causes the appearance of the device of various prevention drunk drivings.But now variously on the market prevent that the device of drunk driving from mainly being to chaufeur, if chaufeur is a drunken driving, the existing drunk driving device of forbidding just can automatic cutting off table motor-car power supply, and car can't be started, for preventing that drunk driving from playing a role.Yet, there is not to install the vehicle of the device prevent drunk driving for present great majority, if chaufeur has just been drunk the joy riding person of steering vehicle, for the external world, especially other vehicles of road driving, traffic police etc. can not play suggesting effect.
Summary of the invention
The purpose of the utility model is; A kind of alarming device of pointing out drunk driving to external world is provided, and this device can be noted going of this vehicle by other chaufeurs of real-time reminding, to prevent the generation of accident; And remind traffic police on duty that this vehicle is accused of drunk driving, in time stop and check.
In order to realize above-mentioned task, the utility model adopts following technical scheme to be achieved:
A kind of alarming device of pointing out drunk driving to external world comprises automobile storage battery and vehicle-mounted computer, is connected with buzzer phone on the vehicle-mounted computer; It is characterized in that; Also comprise the sensor that is connected with vehicle-mounted computer, said sensor is installed in behind bearing circle and the operating seat on the chair, is used to gather the alcohol smell; Vehicle-mounted computer is connected with micro controller system through signal converter, and micro controller system is connected with relay through chip for driving, and relay is connected with alarm lamp through switch.
Other characteristics of the utility model are that said sensor has four at least.
Said alarm lamp is positioned on the forward and backward car plate of vehicle.

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is explained further details.
The specific embodiment
With reference to Fig. 1; Present embodiment provides a kind of alarming device of pointing out drunk driving to external world; Comprise automobile storage battery and vehicle-mounted computer, be connected with buzzer phone on the vehicle-mounted computer, also include the sensor that is connected with vehicle-mounted computer; Said sensor is installed in behind bearing circle and the operating seat on the chair, is used to gather the alcohol smell; Vehicle-mounted computer is connected with micro controller system through signal converter, and micro controller system is connected with relay through chip for driving, and relay is connected with alarm lamp through switch.
In the present embodiment, described sensor has four at least, is connected in parallel; Alarm lamp is positioned on the forward and backward car plate of vehicle.Signal converter is selected the MAX232 chip, and chip for driving is selected the 2803A chip, and micro controller system is selected the 89C2051 chip.
Its principle of work is that behind vehicle launch, sensor is constantly gathered the alcohol smell; Vehicle-mounted computer carries out the alcohol analysis to the information that sensor is sent, and according to the work of analysis result control buzzer phone, when alcohol concentration exceeds standard; Buzzer phone gives the alarm; Through the work of signal converter notice micro controller system, micro controller system sends instruction to relay simultaneously, and Closing Switch makes alarm lamp light.
With reference to Fig. 2, sensor passes information is judged as after " YES " R1 that high level signal is passed to the MAX232 chip through the TXD sending end through the processing of vehicle-mounted computer
INPin is again through R1
OUTPin passes to signal the RXD receiving end of 89C2051 chip.This moment, the voltage transitions through the MAX232 chip changed into the 5V that the 89C2051 chip operation uses to the voltage of 12V, thereby had accomplished the voltage transitions in the signal.
With reference to Fig. 3; After having accomplished the voltage of signals conversion; But the 89C2051 chip just normal switching of operational relay closes action, but because the outgoing current in the micro controller system output signal is very low, is used for increasing outgoing current to drive the coil of relay so also need increase a 2803A chip.
With reference to Fig. 4, the MAX232 chip is a charge pump chip, can accomplish the conversion of two-way TTL/RS-232 level, and its 9,10,11,12 pins are Transistor-Transistor Logic level ends, is used for connecting micro controller system.The TTL/CMOS data convert the RS-232 data to and deliver to computer DP9 plug from T1OUT, T2OUT from T1IN, T2IN input; The RS-232 data of DP9 plug are exported from R1OUT, R2OUT after R1IN, R2IN input convert the TTL/CMOS data to.
With reference to Fig. 5; The 89C2051 chip is a low voltage; 8 micro controller systems of high-performance CMOS, sheet include 2k bytes can be erasable repeatedly read-only Flash program store and the Random Access Data memory device (RAM) of 128bytes, device adopts high density, the nonvolatile storage technologies production of atmel corp; Compatibility standard MCS-51 instruction repertoire, 8 central process units of sheet built-in general-purpose and Flash memory cell.It has 20 pins, 15 two-way I/O (I/O) port, and wherein P1 is 8 complete two-way I/O mouths, two outer middle fractures, two 16 programmable Timer counting machines, two full bidirectional serial communication mouths, a simulation comparison amplifier.
With reference to Fig. 6, can realize the closed action of relay through this 2803A chip.Wherein 9 pins are ground connection, 1,18 pins, and 2,17 pins, 3,16 pins, 4,15 pins, 5,14 pins, 6,13 pins, 7,12 pins, 8,11 pins are a pair of input and output pin, totally 8 pairs.Only utilized 1,18 pins wherein in this patent, promptly the incoming signal of low current from 1 pin can obtain the signal of high electric current from 18 pins, thereby reaches the purpose that improves electric current, has promptly realized the closed action of the switch of relay control warning light.
