Description
Technical field
The invention belongs to the alcohol concentration detection technique field of traffic safety maintenance measure.Be particularly related to the method and the device of alcohol content in a kind of human body.
Background technology
In recent years, along with rapid development of economy, the rapid raising of living standards of the people, the private car that travels on the highway rolls up, and the thing followed traffic hazard that causes of driving when intoxicated takes place again and again.According to interrelated data statistics, in the world 50%～60% traffic hazard with drive when intoxicated relevant.In many countries, traffic accident has become first unexpected death reason, and the economic loss that is caused by traffic hazard is also quite surprising.The Ministry of Public Security drums in recent years and requires various places reinforcement investigation to drive when intoxicated, to reduce the pernicious traffic hazard that causes by driving when intoxicated.Investigate and prosecute with regard to relating to which kind of mode of employing and carry out the problem that alcohol content detects in the human body.
Because after alcohol is absorbed by the body, mainly metabolism in liver of the overwhelming majority, wherein minute quantity alcohol does not have oxygenolysis directly to discharge or discharge from urine through kidney with the sweat gland evaporation from the respiratory tract exhalation or through skin through lung, therefore, judge whether alcohol content exceeds standard in the body, the method for simple possible be on-the-spot detect that human pilot is exhaled or sweat in alcohol content.At present whole world overwhelming majority of countries all adopts expiration formula alcohol content tester that human pilot is carried out scene to detect, with determine alcohol content in measured's body how much.Though exhale to detect the alcohol content that can accurately reflect in theory in the blood of human body, still have the following disadvantages in actual applications: disturbed by peculiar smell such as flue gas; 2, the measured sucks the blowpipe expiration, may pollute mutually; If 3 adopt disposable blowpipe then cause significant wastage; 4, blow gas pressure influential to test result, therefore for serious drunk loss of consciousness or mismatch the personnel of test, exhaling to detect is difficult to carry out; 5, the accuracy of expiration detection is subjected to the influence of selected blowpipe, and improper if blowpipe is selected for use, testing result just can not truly reflect the alcohol content in the human body.
At above-mentioned the deficiencies in the prior art, the present invention looks for another way, adopted by detecting finger sweat and judged the driver whether alcohol content exceeds standard, mutual pollution when preventing to exhale detection, design hommization more, be not subjected to simultaneously the interference of surrounding environment, other people factor, testing result is more accurate.
Summary of the invention
The objective of the invention is at above-mentioned the deficiencies in the prior art, thereby the method and the device of alcohol content in a kind of human body are provided.
The method of alcohol content is characterized in that in a kind of human body, and this method is to determine alcohol content in the blood of human body by detecting sweat on the finger; Concrete steps are as follows:
1) detected person holds pick-up unit, the sweat steam acquisition window above any finger contact alcohol sensor;
2) well heater that is arranged in the alcohol sensor continued after the heating several seconds, the sweat rapid evaporation on the finger, and the evaporation sweat is sampled by alcohol sensor automatically by acquisition window; Sensor internal has heater, and the heat that sensor distributes can be accelerated the evaporation and the diffusion of finger sweat.
3) alcohol sensor is analyzed sweat evaporation gas, and alcohol sensor is quick on the draw the highest to alcohol gas;
4) step 3) is analyzed the gained data and is converted digital data transmission to singlechip microprocessor through signal condition and A/D;
5) singlechip microprocessor sends to digital display screen after with signal Processing and shows alcohol content in detected person's body.
The device of alcohol content in a kind of human body, it is characterized in that, in the front of Long Circle housing 2 digital display screen 4 is housed, below the digital display screen 4 is gauge tap 3, sweat steam acquisition window 1 is set in the side of housing 2, alcohol sensor 6 is installed in the housing 2 at sweat steam acquisition window 1 back side, and signal condition and A/D conversion 7, singlechip microprocessor 8 also are installed in housing 2; Alcohol sensor 6 is connected the display driver chip of singlechip microprocessor 8 output terminals connection digital display screen 4 by signal condition and A/D conversion 7 with singlechip microprocessor 8; D.C. regulated power supply 5 is powered to each several part respectively.
Described digital display screen is LCD or LED display.
The invention has the beneficial effects as follows the alcohol content that can detect accurately, easily in the human pilot body.Pick-up unit is simple and practical, stable performance, detection data are accurate, can also can be used for human pilot and test oneself after drinking as the judgement instrument of administrative law enforcement.The present invention is not subjected to surrounding environment and interference from human factor, avoids infecting mutually in the testing process, and saves material.
Description of drawings
Fig. 1 is the structural representation of alcohol content pick-up unit.
Fig. 2 is the parts composition frame chart of alcohol content pick-up unit.
Embodiment
The invention provides the method and the device of alcohol content in a kind of human body.Further specify technical scheme of the present invention below in conjunction with accompanying drawing and by specific embodiment.
Fig. 1, the structural representation that Figure 2 shows that the alcohol content pick-up unit and parts composition frame chart.The digital display screen 4 that LCD or LED constitute is housed in the front of Long Circle housing 2, below the digital display screen 4 is gauge tap 3, the present invention has only a switch, easy and simple to handle, sweat steam acquisition window 1 is set in the side of housing 2, selects for use QM-NJ9 type microsensor module to make alcohol sensor 6, be installed in the housing 2 at sweat steam acquisition window 1 back side, sensitive high to alcohol gas reaction, stable performance, to detect data accurate; The alcohol sensor of installing in housing 26 is connected the display driver chip of singlechip microprocessor 8 output terminals connection digital display screen 4 by signal condition and A/D conversion 7 with singlechip microprocessor 8; D.C. regulated power supply 5 is powered to each several part respectively.
