Taichung City, as the hub of central Taiwan, plays an essential role in industrial development and transportation systems. However, construction causes severe pollution. The number of people, vehicles, and petition cases increases year by year, which leads to high environmental loads. As a result, air quality needs to be maintained by multiple strategies.
In order to effectively check out the air quality in Taichung City in real time, Taichung City Government Environmental Protection Bureau set up 1,411 air quality sensors around 29 districts in Taichung City. These sensors with the advantages of low cost, small size, and location flexibility, which can transmit monitoring data wirelessly through 4G network (1 data can be transmitted in 1 minute). Besides, these sensors combined with IoT technology, which can precisely mark the street in high resolution, establishing a real-time and uninterrupted Air Quality Data Center.
The monitor locations of air quality sensors and the latest concentration of pollutants can be visualized by using geographic information system, and pollution hotspots and the real-time data can be displayed and searched. At the same time, it also showed the statistics and analysis functions of the data, including cross comparison of trend graphs for the pollutant concentrations and different data for monitoring, such as: PM2.5, TVOC, CO, O3, temperature, relative humidity, anemoclinograph, wind rose, and high-level pollution periods. These data can be applied on regional air quality analysis and pollution source reduction by Environmental Protection Bureau and other related business units. Additionally, AI technology adopted to establish the best warning mechanism for industrial area in Taichung City. Alert notifications through smart phone app- LINE can improve the tracking of pollution sources in industrial areas, increasing the convenience and mobility of inspections. It can also be applied to environmental management measures to improve air quality in Taichung City.
