摘要
面对环境污染不断加剧的问题,推动多种手段进行空气质量的改善,不同的措施对提高空气质量的成果不尽相同.其中洒水降尘是各城市普遍使用的一种改善环境的常用手段,对洒水车抑尘效果进行可靠量化的评价与描述具有重要的价值.本系统依靠北斗的精确定位获取无人机搭载的传感器在不同时空下动态采集数据的位置信息和颗粒物浓度.通过实地实验采集处理数据,能够探测城市道路扬尘状况,可以为动态空气质量监测提供一种有效的手段.
Facing the increasing problems of environmental pollution,a variety of means have been explored to improve the air quality,however,different measures have different influences on improving air quality.Sprinkler is a commonly used means to improve the environment.It is of great value to evaluate and describe the dust suppression effect of sprinkler reliably and quantitatively.Based on the precise positioning of the BDS,the dynamical position information and particle concentration in different time and space collected by UAV equipped with the sensors are obtained.The data collected and processed by field experiments can be used to detect the dust status of urban roads and provide an effective means for dynamic air quality monitoring.
