Radiation environment automatic monitoring station

The radiation environment automatic monitoring station is mainly used to monitor the ambient air quality. This type of station is usually equipped with monitoring equipment for conventional atmospheric parameters (PM2.5, PM10, O3, SO2, NO2, CO) and meteorological parameters (temperature, pressure, humidity, wind direction, wind speed).

Radiation environment automatic monitoring stationAlso known as air quality monitoring stations or meteorological stations, it is mainly used to monitor environmental air quality. This type of station is usually equipped with monitoring equipment for conventional atmospheric parameters (PM2.5, PM10, O3, SO2, NO2, CO) and meteorological parameters (temperature, pressure, humidity, wind direction, wind speed). Using different monitoring principles such as photochemical method, beta ray method, or oscillating balance method, sampling, measuring, and analyzing pollutants present in the atmosphere at fixed points, continuously, or periodically.

Radiation environment automatic monitoring stationIt can be said that it is the basic monitoring facility for environmental air protection in a city or region. According to the standard selection principle, multiple monitoring instruments that comply with national standards are centralized in a small building. The roof of this small building is equipped with various sampling devices, and there is an independent instrument for detecting different monitoring items. All monitoring methods are based on national standards and operated according to regulations to ensure the accuracy and reliability of data.

Atmospheric monitoring stations are divided into various types such as national control points, provincial control points, or municipal control points, and their construction, operation, and maintenance costs are quite expensive. In addition, there is also an air pollution mobile monitoring station, which is a movable monitoring facility used for continuous automatic measurement of various pollutants in the air. When a fixed station malfunctions, it can serve as a substitute station; Alternatively, when the fixed station location is found to be unreasonable, it can be used as a flexible additional station. These two types of monitoring stations complement each other, providing us with more comprehensive and in-depth data support for monitoring atmospheric quality.

The maintenance work of monitoring stations is crucial to ensure the accuracy and reliability of the data they provide. Firstly, it is necessary to ensure that the environment around the monitoring station is not obstructed by tall buildings or trees, in order to ensure the authenticity and reliability of the collected air samples and related data information.

Secondly, for the daily operation of the equipment, regular inspections, analyzer calibration, and system maintenance are required. This includes quality control work on monitoring instruments, such as zero/span checks, accuracy checks, multi-point calibration, and flow checks.

At the same time, environmental air quality monitoring stations need to strictly follow the national and local environmental monitoring and management regulations to standardize operation and management, and ensure the accuracy and reliability of monitoring data. For example, there are specific technical requirements for the operation and maintenance, quality assurance and control, and data validity judgment of continuous automatic monitoring systems for ambient air particulate matter (PM 10, PM 2.5) and ambient air gaseous pollutants (SO2, NO2, O3, CO).

The advantages are mainly reflected in the following aspects:

1. Scientific layout and comprehensive measurement: The layout plan of monitoring stations will be scientifically and reasonably planned based on the development of the economy, population, transportation, and industrial industries to achieve accurate data collection.

2. Data interconnection and sharing: Monitoring stations can not only forward raw data to municipal, provincial, and national environmental protection departments, as well as multi-level and multiple environmental protection centers, but also provide standard interfaces with other government departments, environmental quality networking systems, and other monitoring systems to achieve data exchange and interconnection sharing across different platforms.

3. Pollution assessment and quality daily report: Based on data validity regulations, AQI evaluation technical specifications, data inversion and rounding regulations, etc., conduct data review and processing, make air quality data reviews for each sub station, use test results to release environmental air quality daily reports, forecasts, and regular quality reports to the public, and strengthen the monitoring role of the public.

4. Decision support: The existence of monitoring stations provides important basis for government decision-making.

5. Wide coverage: In addition to the conventional monitoring of six parameter data such as PM2.5, PM10, O3, SO2, NO2, CO, some atmospheric grid monitoring systems can also be extended to monitor various characteristic pollutants such as VOCs, chlorine, hydrogen sulfide, ammonia, etc.

6. Easy to install and use: Miniature devices have lower costs, are easy to use (can be powered by solar energy), are easy to install, can meet current market demand, and can be widely distributed.
