Problems solved by technology

[0003] With the improvement of residents' living standards, there are more and more unavoidable drinking situations, and the nascent surrogate driving industry is becoming more and more prosperous, but the high costs of surrogate driving sometimes make drinkers take risks and take a break. After a period of time, some people will choose to drive by themselves. At this time, alcohol detection equipment is needed to quickly detect the concentration of alcohol. Traditional alcohol detection equipment is large in size and not easy to carry.

Embodiment 1

[0043] figure 1 It shows the implementation process of an alcohol detection method provided by the first embodiment of the present invention, and is described in detail as follows:

[0044] In step S101, the gas breathed in by the person to be tested from the gas channel is received.

[0045] In the specific implementation process, the air inlet of the testing equipment can receive the gas exhaled by the person to be tested. Since the exhaled gas itself has a certain flow rate, the airflow can quickly enter the testing equipment from the air inlet of the testing equipment. The gas enters the gas channel through the air inlet, and finally enters the detection unit of the detection equipment, realizing the function of receiving gas.

[0046] In step S102, the alcohol content in the gas is detected according to the gas inhaled by the subject through the gas channel.

[0047] In the specific implementation process, after the detection device receives the inhaled gas, the detecti...

Embodiment 2

[0054] figure 2 The implementation process of an alcohol detection method provided by the second embodiment of the present invention is shown, and the details are as follows:

[0055] In step S201, the gas breathed in by the person to be tested from the gas channel is received.

[0056] In the specific implementation process, the air inlet of the testing equipment can receive the gas exhaled by the person to be tested. Since the exhaled gas itself has a certain flow rate, the airflow can quickly enter the testing equipment from the air inlet of the testing equipment. The gas enters the gas channel through the air inlet, and finally enters the detection unit of the detection equipment, realizing the function of receiving gas.

[0057] In step S202 , the air pressure value of the inhaled gas is detected, and the alcohol content detection is started when the air pressure value of the inhaled air is greater than or equal to the first threshold.

[0058] In the specific implemen...

Embodiment 3

[0070] Figure 5 A structural diagram of an alcohol detection device provided by the third embodiment of the present invention is shown, and for convenience of description, only parts related to the embodiment of the present invention are shown.

[0071] The receiving unit 501 is used for receiving the gas breathed in by the person to be tested from the gas channel.

[0072] In the specific implementation process, the air inlet of the testing equipment can receive the gas exhaled by the person to be tested. Since the exhaled gas itself has a certain flow rate, the airflow can quickly enter the testing equipment from the air inlet of the testing equipment. The gas enters the gas channel through the air inlet, and finally enters the detection unit of the detection equipment, realizing the function of receiving gas.

[0073] The detection unit 502 is used for detecting the alcohol content in the gas according to the gas breathed in by the person to be tested through the gas chan...

Abstract

The invention is suitable for the field of alcohol detection, and provides an alcohol detection method and device, and the method comprises the steps: receiving gas inhaled by a to-be-tested person from a gas channel; detecting the alcohol content in the gas according to the gas inhaled by the to-be-tested person from the gas channel; obtaining a gas alcohol concentration value according to the alcohol content in the detection gas; and calculating to obtain an output alcohol concentration value according to the gas alcohol concentration value. The alcohol concentration is checked in a convenient mode, and the alcohol concentration of gas blown out by the to-be-tested person is quickly checked and detected.

Description

technical field [0001] The present application relates to the technical field of alcohol detection, in particular to an alcohol detection method and device. Background technique [0002] Since drunk driving has been criminalized, drunk driving cases have become one of the most common types of cases handled by the judiciary. Traffic police usually use breath alcohol detectors as a quick detection tool for drunk driving in the crackdown on drunk driving. The detection of content can effectively avoid the occurrence of traffic accidents, and it can also be widely used in some high-risk areas or areas where drinking is prohibited. [0003] With the improvement of residents' living standards, there are more and more unavoidable drinking situations, and the nascent surrogate driving industry is becoming more and more prosperous, but the high costs of surrogate driving sometimes make drinkers take risks and take a break. After a period of time, some people will choose to drive by ...
