The importance of air quality monitoring in smart cities

Air is an invisible panacea that lives on the earth. We can't see it, but it is vital to us creatures. Therefore, it is essential that the things we breathe are free of pollutants. Under the situation of accelerating urbanization, air pollution has become one of the biggest troublemakers. Severe air quality has a significant impact on morbidity and mortality. It also has an adverse effect on the environment and ecology. Therefore, various agencies list air pollution as one of the main killers on the planet. According to estimates by the World Health Organization, air pollution causes 7 million deaths worldwide every year. Nine out of ten people breathed air that exceeded the limit set by the organization.

Air quality monitoring and maintenance are the main aspects of the smart city model. Real-time analysis of indoor and outdoor air pollutants ensures that we understand the pollutants inhaled. It also enables researchers to analyze data immediately and helps decision makers draft effective action plans to mitigate negative effects.

The air quality monitoring system can realize on-line automatic monitoring of regional air quality. It can monitor the real-time changes of sulfur dioxide, nitrogen dioxide, ozone and inhalable particulate matter in the ambient air all-weather, continuously and automatically, and quickly and accurately collect, process and monitor The data can timely and accurately reflect the regional environmental air quality status and changing laws, and provide detailed data and scientific basis for environmental decision-making, environmental management, and pollution prevention and control of environmental protection departments.

(1) Air quality monitoring system The system integrates multiple environmental parameters such as TSP, PM10, PM2.5, temperature, humidity, wind direction and wind speed, atmospheric pressure, rainfall, etc., and continuously monitors 24 hours a day, and provides air quality data of the construction site. , It can automatically start the monitoring equipment when the alarm value is exceeded, with the characteristics of multi-parameter, real-time, and intelligent;

(2) Transmit and transmit data through the three major networks of sensor networks, wireless networks, and the Internet, and update real-time monitoring data quickly and conveniently;

(3) The cloud computing-based data center platform gathers monitoring data from different regions and different periods of time. It has a large amount of storage space and can perform multi-dimensional, multi-temporal data statistical analysis, which is convenient for the management part to carry out work in an orderly manner, and is also for the establishment of I accumulate data on environmental pollution control standards to promote long-term management of air pollution.

(4) The air quality monitoring system adopts a free modular combination, which can flexibly increase or reduce different monitoring items according to the needs of unorganized pollution monitoring. At the same time, the free modular combination can replace the sensor at any time in the case of a core sensor failure, and Does not affect the normal operation of the entire equipment.
