On-board road dust load navigation vehicle RGR-4 model

RGR-4 Optical Method Vehicle-mounted Road Dust Accumulation Testing

Main Technical Parameters of the System

1、 Purpose

Used for continuous measurement of road dust load.

2、 Working Principle

Utilizes the optical method to measure the concentration of particles raised by the wheels, multiplies by a conversion coefficient to obtain real-time road dust load.

3、 Main Configuration

Vehicle modification, vehicle-mounted measurement system controller, GPS positioning device, wireless communication device, vehicle information communication device, light scattering method particulate concentration tester, optical method air suction path, etc.

4、 Main Functions and Indicators

4.1 Optical Method Measurement Device

4.1.1 Light Scattering Method Particulate Tester

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

4.1.2 Optical Method Air Suction Path

Suction volume 20L/min

4.3 Vehicle-mounted Measurement System Controller

Can set the running distance for a single measurement, display real-time working video of the sampling head; can set the negative pressure value for sampling, initiate the raising and lowering of the sampling device; can display real-time dust concentration and road dust load.

4.4 Special Road Condition Handling During Operation

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

If the dust suction head is blocked by large particles, the system will stop the suction pump, continue moving to dislodge the particles through vibration, automatically raise the sampling head to shed the large particles, and then resume sampling.

5、 Functions of the Upper Computer Data Processing System

5.1 Automatically records driving mileage and calculates sampling area.

5.2 Automatically weighs and records initial and final weights, calculates net weight and concentration values.

5.3 Real-time recording of sampling pressure.

5.4 Features alarm function for too low or too high sampling pressure.

5.5 Has GPS positioning function, records latitude and longitude at the start and end of the sampling interval.

5.6 All the above data can be exported as Excel reports for data processing.

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