摘要
臭氧是现今大气环境中主要污染物质之一,其浓度超标会降低生态环境质量,威胁人类生命健康.调查研究结果显示,影响臭氧污染浓度的关键因素为温度与光照强度,故提出持续高温强光照天气下臭氧污染特征精准提取方法.深入分析持续高温强光照天气对臭氧污染浓度变化的影响,选取49i臭氧分析仪作为臭氧在线监测设备,获取初始臭氧污染监测信号.应用自适应滤波器去除臭氧污染监测信号的噪声,提升臭氧污染监测信号整体质量.计算监测信号对于臭氧污染特性显示的贡献度,以此为基础,判定并提取特征信号,从而实现了臭氧污染特征的精准提取.实验数据显示:应用该方法获得的臭氧污染特征精准提取结果与实际臭氧污染特征精准提取结果相同,充分证实了该方法的有效性.
Abstract
Ozone is one of the main pollutants in the current atmospheric environment,and its excessive concentration can reduce the quality of the ecological environment and threaten human life and health.According to the survey and research results,the key factors affecting the concentration of ozone pollution are temperature and light intensity.Therefore,a precise extraction method for ozone pollution characteristics under continuous high temperature and strong light weather is proposed.Thoroughly analyze the impact of continuous high temperature and strong light weather on changes in ozone pollution concentration,select a 49i ozone analyzer as an online monitoring device for ozone,obtain initial ozone pollution monitoring signals,apply adaptive filters to remove noise from ozone pollution monitoring signals,improve the overall quality of ozone pollution monitoring signals,calculate the contribution of monitoring signals to the display of ozone pollution characteristics,and based on this,judge and extract characteristic signals,thus achieving precise extraction of ozone pollution features.The experimental data shows that the accurate extraction results of ozone pollution features obtained by the proposed method are the same as the actual accurate extraction results of ozone pollution features,fully confirming the effectiveness of the proposed method.
