Summary: Optimization of the original system based on ARM control in response to the low accuracy and real-time data collection problems of the on-line monitoring system for flue gas desulphurization in power plants. Designing an online monitoring system as a whole based on the requirements of the plant's flue gas desulphurization system and based on the programme's presentation of two aspects of hardware, software, key hardware selection, key circuit design, C software design and platform design. Optimized on-line pneumatic desulphurization monitoring systems are applied to a power plant and sensor data, switches are statistically and analytically analysed. The results of the practical application showed that the optimization programme performed well in terms of data accuracy, real-time accuracy and was able to ensure the safe, stable and continuous operation of the FGD online monitoring system. The introduction of smoke from coal-fired installations at power plants has become the main source of atmospheric sulfur dioxide emissions.

The flue gas monitoring system is primarily concerned with monitoring gas emissions in the relevant high-pollution industries. To a large extent, it protects the environment and contributes to the sustainable development of society, especially in the high-pollution public sector, such as fire power.

Product characteristics:* Appearance clean, blast-proof, earthquake-proof,* high-precision, high-resolution, fast-response*

Fourteen-five is the very important phase of socio-economic development that we face, one of the important elements of which is the Blue Sky War. In recent years, China ' s petrochemical and automobile production has grown rapidly and air pollution has increased as a result of production and development needs. While rapid industrial development had contributed to some social progress, it had also resulted in serious atmospheric environmental pollution. At present, the international community is increasingly calling for the protection of the environment in the atmosphere, and China has enacted a number of laws on the protection of the environment in the atmosphere. On 26 November, a member of the Chinese Engineering College and Dean of the Environmental School of the University of Qinghua stated at the China Blue Sky Watch Forum that the core of atmospheric pollution management in 1450 was the synergies between ozone and PM2.5 and between carbon and haze.

Nitrogen oxides detectors can achieve effective monitoring of nitrogen oxides emissions, thereby reducing the occurrence of accidents. Nitrogen oxides, dominated by nitrogen oxides and nitrogen dioxide, are an important cause of photochemical smoke and acid rain. It's called photochemical smoke. Photochemical smoke has a special smell. Stimulating the eyes, Harming plants, It also reduces atmospheric visibility. Nitrogen oxides, which react with water in the air, are the components of acid rain. Nitrogen oxides in the atmosphere are mainly from the burning of fossil fuels and the burning of plants. And the transformation of nitrogen-containing compounds in agricultural soils and animal excreta.I. The key component of the gas detector, the nitrogen oxides detector, is the gas sensor. Gases
