Scope

Scope: This document specifies the system composition, technical requirements, quality assurance and quality control, data validity judgment and grading evaluation standards, and other technical and management requirements for the mobile monitoring of ambient air particulate matter by light scattering method. This document is applicable to the mobile monitoring system of ambient air particulate matter by light scattering method. Main technical content: 5. Instruments and equipment 5.1 The particulate matter monitoring equipment includes five parts: an air sampling module, a particulate matter measurement module, a positioning module, a communication transmission module, and a main control unit. The main control unit is responsible for wirelessly transmitting the collected particulate matter concentration data and position data to the on-board data cloud platform. Each monitoring device transmits a set of data to the platform every second, including a time stamp, spatial coordinate information, and particulate matter concentration data. 5.2 Vehicle particulate matter monitoring equipment can be installed on various vehicles. The vehicles should meet the requirements of GB/T 3730.1-2001, QC/T 41-1992, QC/T 51-2019, and QC/T 54-2016, and be legally permitted vehicles with road rights. It is recommended to utilize shared social resources. The selected vehicles must have non-steerable rear wheels and a single-row single-axle structure. When monitoring on urban roads, the vehicles must comply with the "Regulations on Motor Vehicle Registration". The selected vehicles are social vehicles: the daily average running time of the vehicles to be installed must be >8 hours or the daily mileage must be >200 kilometers, and either of the two indicators must be satisfied. The selected vehicles are special vehicles: there are no hard requirements for running time and mileage, and the route can be customized. 5.3 The on-board data cloud platform comprehensively applies computer t
