H3C + Tsinghua-Solution Joint Smart Atmosphere Solution

In recent years, as the country vigorously promotes the prevention and control of air pollution, people in China, especially those living in the Beijing-Tianjin-Hebei region, can clearly feel the improvement of air quality. The number of smog days was significantly reduced, and the sky turned blue again.

However, people may not know that behind the improvement of China's air pollution control, there is also a contribution from H3C and Tsinghua-Solution (Beijing Tsinghua-Solution Information & Technology Co., Ltd.) in their joint smart atmosphere solution.

H3C has been practicing the ecological strategy of "integrated platform without boundaries" for many years. Relying on its own platform capability advantages, H3C gathers the power of ecological partners for continuous innovation, breakthroughs, and creation of end-to-end seamless solutions, to maximize the customer's value. This solution is the concrete result of H3C's cooperation with its ecological partners to transform complexity into simplicity and to create innovative value for customers.

Imperative air pollution prevention and control

As China attaches greater and greater importance to air quality, it has successively issued a series of specific actions and plans for the prevention and control of air pollution, such as the Air Pollution Prevention and Control Action Plan launched in 2013, and the Three-year Action Plan of Winning the Blue Sky Defense War launched in 2018.

·The implementation of these comprehensive measures of air pollution control has curbed the trend of overall air quality deterioration in China.

· Among them, the Three-Year Action Plan for Winning the Blue Sky Defense War focuses on the Beijing-Tianjin-Hebei region and surrounding areas, the Yangtze River Delta, the Pearl River Delta, and other major pollution-affected areas, pays close attention to the heavy polluted weather in autumn and winter, and proposes the goal of achieving "80% of the number of clear sky days in cities at or above the prefecture level nationwide by 2020". Moreover, the solution puts forward specific assessment requirements for different regions in the country.

Seven steps for air pollution prevention and control

The prevention and control of air pollution is a massive systematic project. Taking pollution sources as an example, dust, automobile exhaust, industrial emissions, and domestic emissions will cause pollution to the atmosphere. The air quality is also affected by air pressure, temperature, wind direction, wind power, rain and snow, and other influencing meteorological factors. Therefore, air pollution prevention and control are complicated and difficult.

According to H3C and Tsinghua-Solution, the air pollution prevention and control work can basically be classified into 7 steps:

Implementation of digital capabilities in air pollution prevention and control

H3C and Tsinghua-Solution implemented digital capabilities in air pollution prevention and control as follows:

· Setting up a target and establishing a dynamic comparison window

Calibrate the target value according to relevant assessment standards, such as air quality index (AQI), PM2.5, and PM10, dynamically compare the actual air quality value obtained from monitoring with the target value to know the gap to the target value and the correctness of the current method, and adjust the action plan accordingly.

· What can be described must be viewed first

In the "Air Pollution Analysis and Diagnosis" system, the contribution of different regions to air pollution can be intuitively viewed, and the discharge and transmission paths of pollution sources are displayed and comprehensively determined based on the meteorological data, pictures, and other information.

In the high-density air pollution grid monitoring system, the distribution status of various air pollutants in each area is monitored in real time, and the PM2.5 concentration status and changing trend are also acquired.

With the help of the statistical analysis of the system, the scientific evaluation of the key factors affecting the air quality of the controlled area is completed. The abnormal data is quickly captured by the system with high temporal and spatial resolution for emergency processing.

The dust source supervision and prevention system performs the monitoring and early warning of areas with pollution exceeding the standard, so as to take effective control measures for dust emission sources such as construction sites in a timely manner.

Through the fixed telemetry, mobile telemetry, black smoke capture, and other devices in the system network, the automobile exhaust remote monitoring system monitors and statistically analyzes the exhaust emissions of automobiles running in the city for overall urban automobile emission research and judgment.

Based on the data of the telemetry device and the snapshot of the license plate, evidences will be collected for automobiles with excessive exhaust emissions to support the next decision.

· Problem analysis and air quality forecast

Based on the data exploration in systems such as the atmospheric grid monitoring system, dust source monitoring and prevention system, automobile exhaust remote monitoring system and other information such as photos and meteorological data, the overall situation of air pollution can be comprehensively judged and analyzed, and the right measures can be taken accordingly. In addition, the technical advantages of the mechanism model and the statistical model are combined to fulfill the dynamic simulation of the changing trend of air pollution, and make accurate predictions on the future air quality of a region in a timely manner.

H3C HPC-based air quality prediction and forecast solution supports the air quality prediction and forecast.

With the powerful computing power of H3C HPC products and the advantages of innovative ideas in the field of numerical and statistical models, this solution can achieve mid- and long-term forecasts (15-day) and short-term (3-hour) forecasts in terms of air quality. The grid accuracy reach 1 km.

Joining hands with long-accumulated capabilities in the environmental protection industry

Over the years, H3C has been deeply involved in the environmental protection industry and has many success stories.

For example, the cloud data center project and the ecological and environmental protection informatization project for the Ministry of Ecology and Environment of PRC, the national comprehensive water quality automatic monitoring platform for the China National Environmental Monitoring Center, the air pollution warning platform for Henan Province, and the environmental protection cloud for Hebei Province.

As a partner of H3C, Tsinghua-Solution has been focusing on product and technology research and development in the field of environmental informatization since its establishment in 1998. After nearly 20 years of development, the company has formed a big data platform covering the entire environmental protection business.

The cooperation between H3C and Tsinghua-Solution is not only a cooperation of boundless ecology, but also a cooperation of complementary advantages and strong alliances. The cooperation between the two parties will undoubtedly make the joint smart atmosphere solution score greater value.

Only by clearly seeing the real reasons behind air pollution and fully understanding the characteristics of its operation patterns, can we truly take the right measures and the precise process method.

The H3C + Tsinghua-Solution joint smart atmosphere solution not only allows decision makers to clearly understand the real-time status of air pollution and discover the underlying causes of pollution, but also easily identify the pollution contributions from different industries and regions, so as to implement forecasting and effective prevention and treatment.
