车载式道路积尘监测系统1

发表时间:2021-12-06 15:32

  要:本文介绍了一种基于车载式道路积尘监测系统,通过路面积尘再激发原理(TRAKER),对道路积尘进行在线监测。该系统采用激光检测技术,对车辆二次激发的路面积尘进行监测,通过算法反推道路的排放因子,并计算其排放潜势。系统在车辆行驶过程中,获取车顶和车底的颗粒物浓度差异,融合GPS、车速等信息后,通过无线网络发送至云端服务器。云端系统通过环保模型、TRAKER算法、GIS等技术,得出道路扬尘排放因子、街道清洁程度等数据产品,为环卫作业指导和重污染天气的车流管理机制,提供详细的理论和数据支撑。

Abstract: The paper introduces a kind of road dust emission measurement system based on vehicle. Through testing re-entrained aerosol kinetic emissions from roads(TRAKER), the road dust accumulation is detected on line. The system uses laser detection technology to test re-entrained aerosol kinetic emissions from roads and calculate the emission factor and emission potentials of road dust. During driving, the system record the concentration of particles in the top and the bottom of the vehicle, integrating GPS, speed and other information, send to the cloud server by the wireless network. Through the GIS and TRAKER technology, the system can get the emission factor of road dust, and provide detailed theory and data support for environmental protection work.

Key words: road dust; TRAKER; emission factor; environmental protection work
