| description | PURPOSE: An electronic nose system and a method is provided to effectively detect harmful gas and impurities contained in volatile oil of a vehicle by applying an artificial neural network to the electronic nose system. CONSTITUTION: When gas is injected through an air pump(1) and a light source(2), an interference filter(3) selectively filters gas introduced. Filtered gas is detected by a sensor so as to transfer gas into a central processing unit(7). At this time, noise contained in gas is removed. The central processing unit(7) stores information about gas in an EEPROM(8) and displays a state of gas in a density display(10). A power section(9) supplies power to a signal processor(6) and the central processing unit(7). A catalyst filter layer is formed so as to improve sensitivity with respect to hydrocarbon gas and to achieve a selectivity with respect to reducing gas.
본 발명은 자동차 휘발유에 포함된 환경 유해가스 및 이물질을 탐지하고 판별하기 위한 소형 전자코시스템 및 방법에 관한 것으로, 후막이나 박막센서로 구성되는 하이브리드형 센서어레이를 사용한 전자코 시스템을 구현함으로써, O3, CO, HC 및 NO2 등과 NH3, CH3SH, (CH3)3N 등과 같은 환경 유해가스 및 이물질을 검출한다. 본 발명의 특징은 우수한 특성의 센서를 설계 및 제작하고 집적화된 센서 시스템에 데이터 처리와 신경망 알고리듬을 접목하여 소형으로 구현한 것이다. |
