【摘要】 恶臭污染作为空气污染的一种给人们生活带来了巨大的影响。所以,研制一套能够准确反映环境污染情况的恶臭污染检测设备具有重要的现实意义。本文设计套以多传感器阵列为基础,可实现对宽浓度范围恶臭气体进行检测的电子鼻设备。该设备可根据不同地区污染气体种类的不同而选择相应的气体传感器,实现对不同成分、不同浓度的恶臭气体的检测,具有良好的适应性。该设备已经能够正常工作,并具有精度高、稳定性好的特点。尤其是可自由组合式传感器阵列的系统设计框架,为系统根据实际环境需要而进行调整提供了极大的灵活性,具有一定的参考价值和应用前景。更多还原

【Abstract】 Odor pollution,one of the air pollution,has brought great impact on people’s lives. So,it has impotant practical siginificance to develop a set of ordor detection equipment that can accurately reflect air pollution. We developed an electronic nose device which is based on a multi-sensor array and can realize the detection of a wide concentration range of malodorous gas. A design of independent assortmnet sensor array is given,which can choose the corresponding sensor for malodorous gas with different types and concentrations in different regions. The system has high adaptability,high precision and good stability. In particular,the system design framework of independent assortment sensor array provides great flexibility for the system to adjust itself according to the difference of the actual environment,which has a certain reference value and application prospects更多还原
