RGR-4Optical methodVehicle road dust accumulation test

Main technical parameters of the system

• purpose

Used for continuous measurement of road dust load.

• working principle

Measure the concentration of particulate matter lifted up by the wheels using optical methods, multiply it by a conversion factor, and obtain real-time road dust load.

• Main Configuration

Vehicle modification, vehicle measurement system controller, GPS positioning device, wireless communication device, vehicle information communication device, light scattering method particle concentration tester, optical method exhaust gas path, etc

• Main functions and indicators

4.1 Optical Measurement Device

4.1.1 Particle testing instrument using light scattering method

Measurement range of 30mg/m3, resolution of 0.1mg/m3

4.1.2 Optical pumping path

Extraction volume 20L/min

4.3 Vehicle mounted measurement system controller

Can set the running distance for a single measurement and display the working video of the sampling head in real time; The negative pressure value for sampling can be set, and the rise and fall of the sampling device can be activated; Real time display of dust concentration and road dust load.

4.4 Special road condition handling during operation

The system has the function of a lifting sampling device to ensure avoidance when the road surface is uneven or there are obstacles.

If the suction head is blocked by large particles of stones, the system will stop the suction pump and continue to move forward. After bouncing, the sampling head will automatically rise to make the large particles of stones fall off and continue sampling work

• Functions of the upper computer data processing system

5.1 Automatically record driving mileage and calculate sampling area

5.2 Automatic weighing and recording of initial and final weight, calculation of net weight and concentration values

5.3 Real time recording of sampling pressure

5.4Equipped with alarm function for low or high sampling pressure

5.5Equipped with GPS positioning function, it records the latitude and longitude at the beginning and end of the sampling interval

5.6The above data can be generated into an Excel report and exported for data processing

5.7Sampling operations and data queries can be performed through a mobile client
