Description

A kind of alcohol tester

Technical field

The utility model relates to the testing tool technical field, relates in particular to a kind of alcohol tester.

Background technology

Alcohol tester is the instrument that is exclusively used in alcohol content in the testing human breath, its detection sensitivity height, measured value is directly perceived, is not subjected to the interference of non-alcohol type gases such as cigarette, cola, coffee, in the road safety management, be widely used in checking the driver of drinking drive vehicle, so that take corresponding measure, end its operation, guarantee passenger's the security of the lives and property, effectively in prevention and the minimizing road passenger transport process,, the driver causes the generation of particularly serious liability accident because of drinking.

Existing alcohol tester storage data adopt the transmission of RS232 serial data more, there is certain inconvenience in the use, and existing alcohol tester adopts the LCD screen to show, its display area is little, resolution is low, and when specifying informations such as record license plate number, needs manually hand-written, forget easily, perhaps make mistakes.

The utility model content

The technical problems to be solved in the utility model provides a kind of alcohol tester.

For solving the problems of the technologies described above, the purpose of this utility model is achieved through the following technical solutions.

A kind of alcohol tester comprises: the circuit part of housing parts, blow gun part, three-way pipe and test, processing, and described blow gun part links to each other by the circuit part of three-way pipe with test, processing; The circuit part of described test, processing comprises CPU, reaches the baroceptor and the alcohol sensor that link to each other with CPU respectively, described baroceptor detects by the air pressure on sebific duct and the described three-way pipe and mouthful links to each other, and described alcohol sensor links to each other with the alcohol gas thief hatch of described three-way pipe by the air valve of sampling.

Wherein, also comprise linking to each other, in order to the organic light emitting display that shows test results with CPU in the described circuit part.

Wherein, also comprise linking to each other, in order to the USB interface of communicating by letter with external mobile digital terminal machine with CPU in the described circuit part.

Wherein, also comprise the car plate database that links to each other with CPU in the described circuit part, by the input media input information.

The utility model adopts organic light emitting display (OLED) large-size screen monitors, makes the user fresh and new, and operation is clearly reminded and high light shows, makes easier operation not to be subjected to the restriction of darkness service time; Adopt three-way pipe structure on the gas circuit, guarantee that gas circuit is unobstructed, sampling accurately, and is residual low, recovers fast, improved the performance of alcohol tester largely; Adopt USB interface transmission data and charge, strengthened the alcohol tester function in one; In the alcohol tester design, adopted the Intelligent license-plate of vehicle input method simultaneously, only needed to select up and down to import complete license plate number, can reduce error rate, raised the efficiency again.

Description of drawings

Fig. 1 is the utility model structural principle block diagram;

Fig. 2 a, Fig. 2 b are three-way pipe synoptic diagram in the utility model.

Embodiment

For ease of the utility model is further understood, now reach specific embodiment in conjunction with the accompanying drawings the utility model is described in detail.

See also shown in Figure 1, when using alcohol tester to test, load onto blow gun and air blowing at inflatable mouth, the gas major part is discharged along the gas outlet, fraction enters air pressure and detects mouth and alcohol gas thief hatch, air pressure detects mouth and is connected to baroceptor with a small hose, baroceptor can be exported electric signal according to variation of gas pressure, when air pressure and time conditions all satisfy sampling, the alcohol tester system CPU provides the sampling air valve that a signal connects for the alcohol gas thief hatch, opens valve and carries out, and a certain amount of breathing gas is sampled into alcohol sensor, according to the alcohol sensor analysis, obtain test result.And the result is presented on the OLED display screen.

Wherein, the OLED display screen possesses autoluminescence, does not need backlight, contrast height, thin thickness, the visual angle is wide, reaction velocity is fast, can be used for the flexibility panel, the serviceability temperature scope wide, structure and processing procedure are simpler.

See also shown in Fig. 2 a, Fig. 2 b, the three-way pipe structure synoptic diagram, comprise that gas outlet 201, inflatable mouth 204, air pressure detect mouth 202, alcohol gas thief hatch 203, air pressure detects mouthful 202 usefulness, one small hose and is connected to baroceptor, and alcohol gas thief hatch 203 links to each other with alcohol sensor by a sampling air valve.Adopt above-mentioned three-way pipe shape-designing, reduce residual shortening return-to-zero-time greatly.

Wherein, also comprise the USB interface that links to each other with CPU, adopt USB interface to replace the RS232 interface, make the transmission data convenient more, but also possess charge function, can finely interconnect with existing equipment.

Wherein, in alcohol screen test, treatment circuit, also comprise the car plate database that links to each other with CPU, write down all license plate number information at the car plate lane database, by input media, the inquiry license board information, idiographic flow is as follows:

1, according to the operation indicating that shows on the OLED screen, tests;

2, after test obtains analysis result, select " keeping records ";

3, move up and down cursor, select " license plate number input ", enter the car plate inputting interface;

4, by the license plate number of key moving cursor modification up and down, the word of need selecting shows in real time in license plate number that also by the modification value of " YES " key affirmation license plate number position present bit, and moving cursor is made amendment to next bit;

5, circulated successively behind 8 characters of license plate number, again by confirming just to enter preservation license plate number state.

The utility model adopts above-mentioned input media, need not change input method when the input license plate number, does not more need to use phonetic discrepancy Chinese character, only needs by selecting license plate number up and down, and input method can be saved time to the law enfrocement official easily, raises the efficiency.

Simultaneously, the utility model adopts the high capacity chargeable lithium cell, memoryless charging, and available USB interface charging, stand-by time is long.

More than a kind of alcohol tester provided by the utility model is described in detail, used specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment just is used for helping to understand core concept of the present utility model; Simultaneously, for one of ordinary skill in the art, according to thought of the present utility model, the part that all can change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
