[0002] With the acceleration of industrialization and the increasing severity of air pollution, air quality monitoring and regulation has become an important part of environmental protection. Industrial plants usually contain multiple areas for product production, processing and storage, which may release a large amount of pollutants such as particulate matter, carbon oxides, sulfur oxides, and nitrogen oxides, which have a negative impact on the surrounding environment and human health. Therefore, air quality monitoring and regulation in these areas has become an important means to ensure air quality. In order to accurately grasp the temporal and spatial distribution characteristics of pollutants, air quality monitoring devices need to have high sensitivity, wide coverage, and real-time data transmission capabilities to provide decision support for relevant departments and managers.

[0003] However, existing air quality monitoring devices still have some significant deficiencies when analyzing and adjusting the evolution characteristics of air quality in industrial plant areas. First, most existing devices focus on the monitoring of a single pollutant and lack the ability to jointly monitor multiple pollutants and analyze spatiotemporal evolution. Secondly, traditional monitoring technology is difficult to adjust air purification measures in a timely manner according to the concentration trend of pollutants. It often relies on manual intervention or preset trigger thresholds, resulting in a slow response speed and inability to adaptively adjust the air quality evolution of industrial plants. Therefore, a new type of air quality monitoring device and regional air quality evolution characteristic analysis method are needed to address the shortcomings of existing technologies in accurate monitoring, spatiotemporal evolution analysis and dynamic adjustment.

[0039] The monitoring module 3 is used to collect air quality information of the area to be tested and to exchange data with the controller 2. The controller 2 obtains the air quality evolution characteristics based on the air quality information. Specifically, the controller 2 calculates the air quality single index I based on the air quality information. i , and the air quality index I iThe air quality evolution characteristics are obtained by associating with the spatiotemporal attributes of the air quality information. Then, the controller 2 sends a control instruction to the adjustment module 4 based on the air quality evolution characteristics, so that the adjustment module 4 purifies the air in the area to be tested in the current working cycle.

Based on the historical air quality evolution characteristics, the central processor 1 sends the pre-adjustment time and space nodes of the next working cycle of the adjustment module 4 to the controller 2. The air quality evolution characteristics obtained by the central processor 1 include the air quality single index I of the area to be measured i , and the air quality index I i The corresponding time and space attributes. The calculation formula of the air quality single index is as follows:
