Rongguang Electronics independently develops road dust load vehicle to assist in ecological environment monitoring in Nanjing City

Yu Xiaoping, the head of the Lishui Environmental Monitoring Station, said that the dust raised by the rear wheels of the aircraft will be "sucked" into the sampling port and transmitted to the analytical instruments in the car's belly. However, dust monitoring relies not only on this sampling port, but also on several small "chimneys" extending into the air on the roof of the car, which are also sampling ports. They each perform their own duties, not only sampling particulate matter in the air, but also monitoring air pollutants such as volatile organic compounds and nitrogen oxides. The sampling port in the air will also sample the dust, and the ground and air will "start working" at the same time. The instrument receives the dust "sucked" into the sampling port and can immediately analyze it to obtain the dust accumulation per square meter.

After the starting of the navigation vehicle, it traveled along the main road of Yongyang Street in Lishui District. The display screen inside the carriage showed the driving trajectory of the navigation vehicle, which was blue. Blue indicates that there is no dust accumulation on this road, and the dust control is up to standard. "Yu Xiaoping told reporters that the monitoring instrument detects dust accumulation in grams and displays it on the screen in five colors: red, orange, yellow, green, and blue. Blue indicates excellent, meaning that the road dust is less than 0.3 grams per square meter. Green, yellow, orange, and red indicate that the monitoring data increases in order, and red is the worst, indicating that the dust is greater than 1.5 grams per square meter. Once the trajectory turns orange and red, the staff in the car must immediately upload a notification.
