Smog air quality digital flag display device, and smog air quality digital flag display system

This creation is about a smog air quality display device and display system, in particular, a smog air quality digital flag display device, and a smog air quality digital flag display system.

In many reports, it has been clearly pointed out that particulate pollutants are one of the main causes of poor air quality in Taiwan. In addition to affecting air quality, particulate pollutants in the atmosphere can also cause harm to human health. Humans inhale particulate pollutants through the nose, throat, and throat through the respiratory function, and deposit them in the lung tissue through the trachea and bronchi. Depending on the particle size, it is deposited on different parts of the human respiratory organs, causing harm to the human respiratory system.

Among the various particulate pollutants, the most important affecting air quality and human health is the Particulate Matter (PM _2.5 ). The so-called "fine aerosol (PM _2.5 )" refers to particles suspended in air with aerodynamic particle size of less than 2.5 μm. PM _2.5 source can be divided into two types: natural output and human behavior output. The PM _2.5 produced by human behavior can be subdivided into primary PM _2.5 particles and derivatized PM _2.5 particles.

Most of the PM _2.5 particles are exhaust gases from the combustion of thermal power plants, petrochemicals or general plants, and are usually released into the atmosphere together with heavy metals, dioxin and incompletely burned organic carbon.

The derivative PM _2.5 particles produced by human behavior include sulfur oxides or nitrogen oxides emitted from public transportation, automobile locomotives, petrochemical industry, organic carbon compounds, sulfates, nitrates and organic carbon produced by sunlight. Fine suspension of particles.

The black carbon in the composition of the fine aerosol (PM _2.5 ), which absorbs a large amount of sunlight, will not only accelerate the melting of the ice in the polar region and cause an increase in the atmospheric temperature, but also affect the presence of suspended particles in the atmosphere. The transmission of light causes various problems that are plagued by environmental opacity and reduced visibility.

Due to the impact of PM _2.5 on the environment and the health of the Chinese people, the Environmental Protection Agency announced on May 14, 101 that the air quality standards were revised, the PM _2.5 air quality standards were updated, and the health impact was prioritized based on the results of the domestic health impact study. Considering, the PM _2.5 daily average concentration value is set to 35 μg/m ³ , and the annual average concentration value is set to 15 μg/m ³ .

For the monitoring of fine aerosols in the atmosphere (PM _{2.5 for} short), in the conventional air quality system monitoring, it is generally used to display banners with different colors in public places to generate warning effects, which not only requires a lot of manpower control, Moreover, it is very inconvenient for the replacement of the warning flag, and often causes problems such as manpower consumption, increased management difficulties, and increased costs.

Therefore, there is an urgent need to develop a problem that does not have conventional techniques, low cost, easy operation, and timely display of fine aerosols (PM _2.5 ), air pollution indicators (PSI), or/and air quality indicators (AQI). The smog air quality digital flag display device and the smog air quality digital flag display system.

In view of the problems of the prior art, the applicant has carefully tested and researched, and has a perseverance spirit to finally conceive the creation, that is, to provide a smog air quality digital flag display device and a smog air quality digital flag display system. It can be set to be installed in public places to instantly display the indicators and conditions of air pollution according to the smog. For example, the PM _2.5 value of fine aerosols in the air or the pollutant standard index (PSI) for color conversion. It is also possible to obtain the air quality values related to the installation location through the network to the air quality index (AQI) related website at a predetermined time, for example, when the whole point is reached, for example, the PM _2.5 value. After the operation, it is displayed through visual effects, for example, through color or text. Through this fully automatic cloud digital smog air quality digital flag display device, the manual Internet access inquiry and the replacement of the flag color are eliminated, and several color changes can be made to achieve the function of warning and providing air quality status.

In one embodiment, the present invention provides a smog air quality digital flag display device including a display unit, an arithmetic unit, and a cloud connection unit.
