Precise dust treatment，data empowerment：Road Dust Load Monitoring Project for Navigation in a City, Shanxi Province

1、 The urgent need for dust control driven by policies

As an important energy base and industrial province in China, improving air quality has always been the core task of ecological environment protection in Shanxi Province. The Implementation Plan for the Implementation of the Action Plan for Continuous Improvement of Air Quality in Shanxi Province requires that by 2025, the PM2.5 concentration in Datong City should be stably controlled below 25 micrograms/cubic meter, Lvliang City should be stably controlled below 28 micrograms/cubic meter, Shuozhou City should be stably controlled below 30 micrograms/cubic meter, Xinzhou City, Changzhi City, and Jincheng City should be stably controlled below 35 micrograms/cubic meter, Jinzhong City and Yangquan City should strive to be controlled below 35 micrograms/cubic meter, Taiyuan City should strive to be controlled below 38 micrograms/cubic meter, Linfen City and Yuncheng City should strive to be controlled below 44 micrograms/cubic meter, laying the foundation for the comprehensive compliance of PM2.5 concentration in prefecture level cities by 2027. ”As the main source of urban dust, road dust accumulation directly affects the concentration of PM2.5 and PM10. To this end, the Ecological Environment Bureau of a certain city in Shanxi Province, in conjunction with Zhiyi Times, has introduced the ZWIN-CFH08 Road Dust Load Navigation Monitoring System to build a "full coverage, real-time perception, data-driven" road dust monitoring system, promoting the transformation of dust control from "experience judgment" to "scientific precision".

2、 The core demand for precise dust control

As an important transportation hub in Shanxi Province and a strategic pivot city on the New Eurasian Continental Bridge and Silk Road Economic Belt, a certain city has a well connected road transportation network that provides convenience. However, the problem of road dust accumulation caused by construction and vehicle traffic is becoming increasingly prominent. Compared with traditional monitoring methods that are inefficient and have outdated data, the city urgently needs an efficient, accurate, and intelligent road dust monitoring system to achieve the goal of "full coverage, real-time monitoring, and data empowerment" in dust control.

The prominent advantages of the road dust load navigation monitoring system are:

Real time dynamic monitoringData collection can be completed while the vehicle is in motion, without being limited by time and space.

Accurately locate pollutionBy using big data algorithms to calculate dust accumulation load and dust emission factors, accurately identify high pollution road sections.

Multi parameter comprehensive monitoringCan synchronously collect PM2.5, PM10 and other particulate matter concentrations and meteorological data, supporting video surveillance fusion.

Automatically generate reportsAfter the flight is completed, the system automatically generates a flight report, extracts data from the excessive road sections, and forms a dust pollution calendar chart.

3、 Accurate Password Implemented by Technology

The Zhiyi Era Road Dust Load Navigation Monitoring System consists of a particulate matter collection unit, a particulate matter monitoring unit, a data acquisition and transmission unit, a power supply unit, a vehicle positioning system, an auxiliary unit, and a visualization platform. It integrates online monitoring, data calculation, map matching, video monitoring, data transmission, and automatic statistics functions. By monitoring the dust concentration carried by the wheels, the road dust load is evaluated, and the generated navigation standard map clearly displays the road pollution situation. The system automatically monitors dust load data during normal vehicle operation, which has the advantages of not affecting traffic, high monitoring efficiency, and clear and visible results.

The implementation of the project is a concrete practice of implementing the "Action Plan for Continuous Improvement of Air Quality" in Shanxi Province, and also a vivid case of "technology pollution control and precise dust control". The ZWIN-CFH08 system of Zhiyi Era provides a new solution for urban dust control through "mobile navigation+real-time monitoring+data analysis+intelligent reporting", helping Shanxi Province achieve the goal of "continuous improvement of air quality".
