Particularly, in the present embodiment, as shown in figure 4, battery pack 3 by 18650 lithium battery groups 3 of 2 section 3.7V at battery
Capacity is big, can long-time independent operating when fully charged.
Particularly, in the present embodiment, as shown in figure 8, using 0.96 cun of OLED liquid crystal display.It possesses ultrafast
Response speed and frivolous advantage.Good in anti-interference performance, inside are solid-state structure, and without liquid substance, therefore anti-seismic performance is more
It gets well, not fear of throwing；The problem of almost without visible angle, even if watching under very big visual angle, picture is still undistorted；Meet existing
The various demands in field, it realizes that function is, shows current alcohol detectable concentration value, drunk driving standard value etc..
Particularly, in the present embodiment, as shown in fig. 7, control chip 7 uses STC89C52 single chip, with other models
Single-chip microcontroller is compared, and STC89C52 single chip anti-interference ability is stronger, and power consumption is smaller.The power supply erasing of+5V or+12V can be straight
It connects and modifies its program, it is more convenient for application single-chip microcontroller, and the limitation of its operating voltage also more greatly 2.7-6V, because
And the influence of voltage fluctuation is more very little for it, is fully able to meet the needs of single-chip microcontroller, therefore STC89C52 monolithic
Machine is to design to drive when intoxicated to detect the more preferably selection of locking system single-chip microcontroller type selecting.
Particularly, in the present embodiment, be integrated on main control board 5 relay 6, control chip 7, voice module 9, with
And gsm communication module 10.When system works, is detected, detected in by side ring border by 4 alcohol sensors 2 first
Analog quantity enters A/D converter and is converted into digital quantity by signal modulation, then into single-chip microcontroller, using single-chip microcontroller as core into
The a series of control of row, subsequent sequence of operations includes signal acquisition process and display, 6 circuit of relay etc..Basic step
It is that the response signal measured by alcohol sensor 2 is first acquired by single-chip microcontroller, then carries out A/D conversion, the number after conversion
Signal is stored in data storage device, and last single-chip microcontroller analyzes the gas concentration detected by operation, while will be divided
The standard value for analysing obtained value and setting compares, and carries out judging whether to alarm according to final result, relay 6 is disconnected,
The comparing result of measured value and standard value is shown on LED LCD screen again.
Particularly, in the present embodiment, as shown in figure 5, the main function of relay 6 is when alcohol sensor 2 detects
When being higher than standard value to the alcohol content in driver's exhaled gas, it can make engine that can not light a fire, so this can be certainly
The executing agency of dynamic cutting car engine power supply just becomes particularly important, is based on such requirement, the present embodiment has selected relay
6 module of device, car engine power supply is opened or closed by the movement of relay 6.
Particularly, in the present embodiment, as shown in figure 9, voice module 9 is newest in 2001 using U.S. ISD company
It releases a kind of 8~20 seconds single hop audio record circuit ISD18102 of monolithic and oscillator is included using CMOS technology, microphone is preposition
Amplification, automatic growth control, anti-aliasing filter, speaker drive and FLASH array.The pin and voice module of single-chip microcontroller
9 are connected, and open voice broadcast function.When the pin of single-chip microcontroller exports fixed frequency level, voice module 9 starts casting record
Sound.Pin is in high level under normal circumstances, and when system enters time of fire alarming, single-chip microcontroller controls pin and exports certain frequency side
Wave, voice module 9 start playback and realize sound alarm function.
Particularly, in the present embodiment, as shown in Figure 10, gsm communication module 10 uses SIM900A communication module.This
Communication module is born the responsibility the task of long distance monitoring people's Alarm Communication, and when driver's drunk driving is more than setting value, main control board 5 is given
Order allows SIM900A to send alarm message to user out.Because SIM900A uses ARM9216EJ-S kernel, it is possible to realize
It sends short messages and other data service functions rapidly, is realized by AT instruction, while the function of remote short messages prompting may be implemented
Energy.
Preferably, in the present embodiment, selecting control chip 7 of the STC89C52 single chip as the present embodiment, alcohol is passed
The alcohol concentration that sensor 2 detects in air in test environment sends SCM system to after converting again via A/D converter again,
It is controlled accordingly by the outside peripheral equipment transmission of single-chip microcontroller again.The function of finally realizing is driven by the test of alcohol sensor 2
Alcohol content in the gas of the person's of sailing exhalation, 4 acts of OLED liquid crystal screen show and judge whether the value that is above standard, and drive when detecting
Alcohol content in member's exhaled gas is above standard when being worth, and will just trigger warning device and pass through 8 loop play of loudspeaker " please noting that
Safety, treasures life, not drive when intoxicated ", it sends on exceeded signal to designated mobile phone, and automobile is cut off by relay 6
Engine power start automobile can not, prevent the generation of drunk driving.In the present embodiment, it is sensed using fuel cell type alcohol
Device 2 can detect the alcohol content in driver's exhaled gas, and judge whether to be more than preset standard value.
Alcohol concentration must be shown by hardware handles, enable a driver to be clearly seen that insobriety, cannot be driven again
Vehicle is based on such requirement, this reality so needing to select a kind of display instrument to show the intracorporal alcohol concentration value of driver
Apply example selection is exactly OLED liquid crystal display.
Preferably, a variety of warning functions of the present embodiment realization, GSM mobile handset communication function, field speech warning function, for
Drunk driving situation, guardian can quickly know driver conditions, convenient to remind in time.Display screen, fast and easy are arranged at device top
State status of drinking is detected, facilitates and self detects.Relay 6 disconnects car engine power supply, makes automobile auto extinguishing, prevents drunk driving
Occur.
It is noted that the utility model protection is hardware configuration, it is not claimed as control method.Above only
For a preferable embodiment in the utility model embodiment.But the utility model is not limited to the embodiment above, it is all
Any equivalent change and modification done by the utility model, range of the generated function without departing from this programme
When, belong to the protection scope of the utility model.
