A real-time calculation platform of ship air pollutant emission based on Flink

Water transportation is not only an important part of the modern transportation system, but also an important source of air pollution. The air pollution in inland rivers, ports and coastal areas caused by ships is becoming increasing serious. Real-time calculation and early-warning of air pollutant emissions from ships can provide a basis of rapid-decision-making for relevant departments. To realize a real-time monitoring of air pollutant emission, a real-time calculation platform of air pollutant emission is proposed. This platform uses dynamic power method to calculate the ship air pollution based on the automatic identification system (AIS) data. The calculation is implemented by the stream computing of Flink. By taking advantage of the dynamization of the AIS data and real-time performance of Flink, this platform can improve the estimation of the ship air pollutant emission. It provides the data supporting for the blue-sky defense war.
