Abstract
(EN)

PROBLEM TO BE SOLVED: To provide a chemical vapor sensor, capable of passively measuring the focusing chemical species-like matter with high accuracy and also capable of passively measuring chemical specificity in the selective region for the use of in a safety system.

SOLUTION: The vapor concentrator amplifies the concentration of the vapor of the chemical matter for the use in an infrared ray detector. The compensation of environmental variations that affect the passive measurement of the chemical vapor sensor is provided. To the environmental variations, when the foreign vapor or sample vapor drifts to the suction port for sampling, at least a part of the sample vapor is turned away by the air flow. For example, ethanol vapor is measured, the measured value of the carbon dioxide tracer is used for adjusting the environmental variations for calculating the measured value of ethanol vapor. In one embodiment, for calculating alcohol concentration in the blood, artificial time filter is set so that the output of the carbon dioxide sensor is made match with the time dependence of the ethanol sensor.

【課題】安全システムで使用するため、高感度で着目化学種状物を受動的に測定し、選択領域で化学的特異性を受動的に測定できる化学蒸気センサーが提供される。
【解決手段】蒸気濃縮器は化学物質蒸気状物の濃度を赤外線検出器で使用するため検出可能レベルまで増幅する。化学蒸気センサーの受動的測定に影響を及ぼす環境変動の補償が提供される。環境変動には、周囲の空気中の外来的な蒸気又はサンプル蒸気が蒸気状物源から化学物質センサーのサンプリング用吸引口へとドリフトするときサンプル蒸気の少なくとも一部分を逸らす空気流れが含まれ得る。一例では、エタノール蒸気が測定され、二酸化炭素トレーサー測定値が環境変動に対して調整されるエタノール蒸気測定値を計算するため使用される。一態様では、血液アルコール濃度を計算するため人工時間フィルターが二酸化炭素センサーの出力をエタノールセンサーの時間依存性に合致させるように設定される。
