In order to strengthen the scientific and fine management level of urban roads, improve the pollution control decision. Using vehicle monitoring data for special areas (such as controlled, provincial control air quality automatic monitoring sites and other key areas) is analyzed, find the main pollution sources around the sensitive area, provide data support for key areas targeted governance, promote multi-sectoral data connectivity and joint analysis, especially for road dust and dust problems in environmental protection, building, urban management, traffic and sanitation department data dynamic fusion. The organic combination of grid air quality monitoring, pollution source emission monitoring, atmospheric environment super station monitoring, pollution source list data, meteorological data, urban management data and muck truck data can realize the interconnection of environmental protection big data, and improve the scientific and intelligent level of urban air quality management on the whole.

Road dust

Road dust refers to the particulate matter formed by the dust on the road and street under the action of fixed dynamic conditions (wind force, motor vehicle tunnel pressure or crowd activity). Road dust is the main source of urban air particles, which has become a great public hazard in cities.

Dust accumulation load

Dust load refers to the dust mass passing through 200 mesh (75 μ m) standard sieve on the road surface per unit area, in g / m2. It is an important parameter affecting the emission coefficient of PM10 and PM2.5. The road dust load is not monitoring the roadside dust, but the dust monitoring of the road area.

Road dust load vehicle mobile monitoring system

The system that raises the loose particles on the road surface, automatically monitors the road dust through the on-board sampling and monitoring device, and calculates the road dust load with relevant influence parameters, is referred to as the on-board mobile monitoring system.

OSEN-DLJC road dust load fast navigation monitoring terminal is an online real-time monitoring of particulate matter in the atmosphere and dust raised by road vehicles. The collected data information will be transmitted to the intelligent cloud platform for processing, and customers will be given monitoring information, including the particle value and the points.

software function

1.  Road air quality distribution

The city mobile air monitoring network provides road data query, display and dynamic computing tools based on geographic information platform, and provides users with a free mining and use data platform that can be flexibly adjusted according to their own business from three data dimensions, so as to improve the efficiency of users to explore a large amount of monitoring data.

2.  Real-time thematic map of the air quality road network

Combined with geographic information, the massive second-level monitoring data uploaded by vehicles can be visually displayed, vividly showing the real-time change trend of air quality on the road and the pollution distribution. The system can switch the display content according to different display levels of the map, display the air quality data of urban trunk roads in large-scale areas, air quality monitoring results of street level roads can be displayed in mid-scale areas, and road air quality data of street level can be displayed at small-scale level.

3.  Road dust accumulation monitoring and display

Road dust monitoring display, through the road dust display based on the geographic information platform, vividly display the street dust pollution.

4. Road dust inventory ranking

Through the cumulative monitoring data over a period of time, the street cleanliness of the city is ranked, and the pollution degree based on road attributes is analyzed.

5.  Real-time data for vehicles

Can be determined according to different pollution parameters (TSP, PM10, PM2.5) Display the real-time location and monitoring concentration of each vehicle, and you can also view the real-time temperature and humidity information.

6. Overstandard monitoring

The road sections exceeding the standard were extracted and displayed, and the roads with different pollution levels were displayed independently.
