Exhaled breath detection apparatus, calibration information generation apparatus, and non-transitory computer-readable medium

An exhaled breath detection apparatus which detects alcohol contained in exhaled breath in an operator’s cabin of a mobile body, comprising:

• a component detection unit which obtains, through detection, detection information indicating a concentration of the alcohol and a concentration of carbon dioxide contained in exhaled breath;
• an air supply unit which is operable in a first state and a second state different from the first state in at least one of an airflow rate or an airflow direction, which supplies air from the operator’s cabin to the component detection unit;
• a calibration information generation unit which generates calibration information for calibrating a concentration of the carbon dioxide, based on the detection information of the carbon dioxide detected by the component detection unit when the air supply unit is in the first state;
• and
• a result correction unit which corrects a detection result of the alcohol based on a calibrated concentration obtained by calibrating, based on the calibration information, the detection information of the carbon dioxide detected by the component detection unit when the air supply unit is in the second state.

An exhaled breath detection apparatus which detects alcohol contained in exhaled breath in an operator’s cabin of a mobile body, comprising:

• an alcohol concentration measurement unit which measures a concentration of the alcohol contained in exhaled breath;
• a carbon dioxide concentration measurement unit which measures a concentration of carbon dioxide contained in exhaled breath;
• a calibration information generation unit which generates calibration information for calibrating a concentration of the carbon dioxide, based on detection information of the carbon dioxide obtained through multiple detections by the carbon dioxide concentration measurement unit;
• and
• a result correction unit which corrects a detection result of the alcohol based on a calibrated concentration of the carbon dioxide obtained through calibration with the calibration information.
