Description

Technical Field

[0001] The present invention relates to the field of glass production, and particularly to a method and system for real-time monitoring and early warning of glass pollutants. Background Art

A large amount of pollutants will be generated during the glass production process, such as particulate matter, sulfur dioxide, nitrogen oxides, heavy metals, etc. These pollutants not only cause serious harm to the environment, but also affect the health of surrounding residents.

[0003] Existing early warning models may be established based on historical data, and are insufficiently adaptable to changes in glass production processes or new pollution situations.

The setting of the warning threshold may be too single or fixed, lacking flexibility. For example, for different production stages, different pollutant types, or different environmental conditions, different warning thresholds may be required, but existing systems may not be able to automatically adjust the threshold. The setting of the warning threshold lacks a scientific basis and is only based on experience or regulatory requirements, which may lead to false alarms or missed alarms.
