Abstract
The utility model relates to a handheld intelligent alcohol detector. Collected detected gas is conveyed to a pressure sensor and a signal conditioning circuit by a gas collection pipeline; gas pressure is detected and is compared with a standard value; when the gas pressure is insufficient, the detected gas is collected again; after the gas pressure reaches the standard, the detected gas is transferred to an electrochemistry alcohol sensor and the signal conditioning circuit by an air pump driving circuit; a detection result is directly displayed on a touch control liquid crystal display screen; if the alcohol concentration of the tested gas exceeds the standard, a picture-taking module sends a signal of regulation-violation information by a wireless transmitting module; the signal is transferred to a minityp printer and a minitype memory card by a wireless receiving module; and the normal operation of each module is controlled by a single chip microcomputer and a peripheral circuit. The handheld intelligent alcohol detector disclosed by the utility model has the advantages of high measurement precision and high result displaying speed and is suitable to frequently use at a high density.
Description
Technical field
The utility model belongs to the checkout equipment field, relates to a kind of handheld-type intelligent alcohol content tester, is applicable to that the automobile driver alcohol concentration detects.
Background technology
In recent years; Along with China's rapid economy development; The continuous increase of mileage in highway open to traffic, motor vehicle and the vehicle driver in the whole nation causes the road traffic accident of China high, causes the tragedy of car crash to show repeatedly with us because of driving when intoxicated.
Judge whether to drive when intoxicated, method is the alcohol content of checking immediately in the human pilot blood the most accurately.But in illegal processing or highway communication routine inspection, on-the-spot to extract blood unpractical often, and deliver to hospital extract blood again can be different with at the scene the time because of time the alcohol concentration in the chien shih blood of having spent on the road.But after the drinking an of people, alcohol need be through digestion or chemical change, but directly absorbs in the blood vessel through organs such as mouth, stomach, small intestines.When blood flow through lung the time, the barrier film that the alcohol molecule of some will be crossed alveolar gets into the lung chamber, and can breathe out with people's breathing.If exhaling with medium dynamics dark air-breathing back, the measured reaches more than three seconds; The gas of at this moment breathing out is exactly the gas that comes out from depths, lung chamber; Alcohol content in the expiration and the alcohol content ratio in the blood are 2200: 1 (also being so-called partition factor), and promptly the breath of 2200ml is identical with the alcohol content of 1ml blood.Therefore, on this theoretical foundation, the method for simple possible is the on-the-spot alcohol content of human pilot in exhaling that detect.Whether the nearly all country in the whole world all adopts the expiration alcohol tester that human pilot is carried out the scene detection at present, drive when intoxicated to confirm the measured.
In China, because the time that the alcohol detection standard is implemented is not long, a lot of local necessary alcohol testers that all also are not equipped with; And domestic alcohol tester calibration and the calibrating installation that lacks necessity; The drift of instrument is bigger, and accuracy, the authority of use all are under suspicion, in addition in the middle of the traffic police process; Human pilot has the refusal test or the personnel that mismatch can not find the drunk driving evidence and takes measures for refusing afterwards; Therefore, how to promote, strengthen using and calibrating of alcohol tester in China, caused the great attention of relevant departments.
Summary of the invention
The utility model problem to be solved is; Overcome the deficiency of prior art; A kind of handheld-type intelligent alcohol content tester is provided; This detector compact conformation, functional integration height; Can accurately detect alcohol content in driver's breath delicately and judge whether drunk driving, can comprise information such as testDate, time, license plate number, license, people's police's warning signal on duty, alcohol concentration result, environment temperature through wireless printing again, and adopt touch screen to have functions such as beautiful interface operation intuitive and convenient.
The utility model solves its technical matters and takes following technical scheme to realize:
A kind of handheld-type intelligent alcohol content tester that provides according to the utility model; Comprise gas collecting pipeline, pressure transducer and signal conditioning circuit, air pump driving circuit, galvanochemistry alcohol sensor and signal conditioning circuit, digital thermometer, single-chip microcomputer and peripheral circuit, wireless sending module, wireless receiving module, power module, photo module, touch liquid crystal display screen, mini-printer, microstorage card, button; The tested gas delivery that described gas collecting pipeline will collect is to pressure transducer and signal conditioning circuit; Detected gas pressure and standard value are relatively; The gaseous tension deficiency is then gathered tested gas again; The tested gas in gaseous tension back up to standard is delivered to galvanochemistry alcohol sensor and signal conditioning circuit through the air pump driving circuit; Testing result directly is presented on the touch liquid crystal display screen, tested gaseous alcohol concentration over-standard, and photo module is sent signal with violation information through wireless sending module; Pass to mini-printer and microstorage card through wireless receiving module, the normal operation of each module is all through single-chip microcomputer and peripheral circuit control.
The utility model compared with prior art has significant advantage and beneficial effect.
The utility model adopts high sensitivity fuel cell alcohol sensor to satisfy the error of indication and repeated requirement; Possess the wireless printing function, print What comprises information such as testDate, time, license plate number, license, people's police's warning signal on duty, alcohol concentration result, environment temperature, shows the time-write interval; Has the undervoltage warning function; The sensor self-checking function; The result stores and transfers look facility; The demonstration of alcohol quality concentration switching in alcohol quality concentration and the blood in the breath; Warning function exceeds standard; Driver's passport NO. input memory function; Read the function of driver IC control card information; The Operational Management System that adopts advanced graphical independent research is as user interface; Outstanding power management, the saves energy of can shutting down automatically.。
The embodiment of the utility model is provided by following examples and accompanying drawing thereof in detail.
