Problems solved by technology
[0003] At present, most of the equipment used for ethanol gas detection adopts infrared, catalytic combustion or electrochemical sensor type. These equipment are generally large in size and low in sensitivity. At the same time, the deviation of the detection results is large due to the drift of the baseline.

The invention discloses an ethyl alcohol gas detection system which comprises a gas sensor, a data collection device, a controller, a data storage device and a displayer. The gas sensor is used for detecting ethyl alcohol gas and is a metal oxide semiconductor ethyl alcohol gas sensor. The data collection device is connected with the gas sensor and used for collecting signals generated by the gas sensor, and the data collection device is an A / D module. The controller is connected with the data collection device and used for receiving data sent by the data collection device for calculation analysis. The controller is a single chip microcomputer. The data storage device is connected with the controller and receives and stores data information forwarded by the controller. The displayer is connected with the controller and used for displaying the concentration of the ethyl alcohol gas. The self-adaptation correction method is adopted, so that whether an ethyl alcohol gas detector is in the normal or damaged state is timely judged; the ethyl alcohol gas detection system is small in size, convenient to carry and particularly applicable to testing examination for drunk driving in a traffic law enforcement department.
Description
technical field [0001] The invention relates to the technical field of gas detection, in particular to an ethanol gas detection system and a detection method thereof. Background technique [0002] Ethanol is ubiquitous in the air because it is very volatile. Ethanol gas is easy to burn and cause fires when it comes into contact with open flames or chemicals; and when the ethanol in the air reaches a certain concentration, it will also have some side effects on the human body and affect human health. . In addition, drunk driving is a major hazard that causes traffic accidents. Carrying out a breath alcohol test on drivers is an effective means to judge whether drunk driving and curb drunk driving. The human body will also produce a small amount of ethanol in the human body due to metabolic disorders caused by certain lesions. Through the detection of the ethanol content in the breath, some lesions of the human body can be discovered in advance, so as to be treated in time. ...
