Problems solved by technology

However, if only sensors are used for monitoring, there are still defects such as unreasonable monitoring points, incomplete parameters, and inherent zero drift, temperature drift, and time drift of sensors, which will cause inaccurate data in the monitoring system.
[0003] The inventor of the present application found that the current monitoring system will alarm as long as the concentration of pollutants exceeds the standard.
The alarm issued by the monitoring system may be caused by meteorological conditions. If the alarm is caused by meteorological transmission, there is no pollution source in the area that caused the alarm, and such an alarm will generate false alarms.

Abstract

The application discloses a method and device for air pollution alarm. The method comprises: determining a correlation function between pollutant concentration data and meteorological data according to the pollutant concentration data and meteorological data in an area needing monitoring within predetermined period of time; determining a predicted pollutant concentration based on real-time meteorological data of the area needing monitoring and the correlation function; and sending out an alarm instruction under the conditions of determining that the real-time pollutant concentration data in the area needing monitoring are higher than the predicted pollutant concentration and a difference between the real-time pollutant concentration data and the predicted pollutant concentration is greaterthan a preset value.

Description

technical field [0001] The application belongs to the field of environmental monitoring, and in particular relates to a method and device for alarming air pollution. Background technique [0002] Environmental quality issues are getting more and more attention. In the prevention and control of air pollution, by installing monitoring sensors, the monitoring area can be fully distributed and covered, eliminating monitoring blind spots, and providing strong support for air environment supervision. However, if only sensors are used for monitoring, there are still defects such as unreasonable monitoring points, incomplete parameters, and inherent zero drift, temperature drift, and time drift of sensors, which will cause inaccurate data in the monitoring system. [0003] The inventor of the present application found that the current monitoring system will alarm as long as the concentration of pollutants exceeds the standard. The alarm issued by the monitoring system may be caused...
