In the field of atmospheric management, Jinan’s recent efforts have been impressive. At the end of October last year, more than 100 taxis were equipped with an atmospheric particulate monitoring system, which became a mobile monitoring station. This is also a footnote for Jinan to seek change.
The airborne particulate monitoring system was developed by a team led by Associate Professor Schu Chun of Shandong University. The principle is to monitor PM2.5 and PM10 with laser pointer. Basically, data can be sent once every 3 seconds and installed in a taxi. It is possible to monitor the concentration of particulate matter wherever it is.
This technology is the first in China and the world. More than 100 taxis equipped with this system travel through the streets every day, which can monitor the pollution level in many corners of the city. Once the threshold is exceeded, the system will be mobilized. Environmental protection and urban management personnel in the surrounding area should take timely measures or sprinkle water or interfere with pollution sources.
The public figures of the Jinan Environmental Protection Bureau show that the system can cover more than 95% of urban motor vehicle roads every day, and continuous monitoring can be achieved through multi-vehicle relay.
Years ago, Si Shuchun participated in a PM2.5 measurement research project supported by the state funds. He accidentally encountered an imported laser pointer particle counter, which was large in size, 30 cm in length, width and height. The price was very expensive and very delicate. The maintenance cost is extremely high. “At the time, I thought, could we use laser measurement technology to create a low-cost alternative, install it on mobile devices and monitor data in real time.” Si Shuchun said that after the joint efforts of the research and development team of six or seven people, it took time. After more than three years, the product finally came out.
