Application Abstract: This project carried out research on online monitoring and real-time monitoring technology of air pollutants in ship emission control area according to the supervision requirements of ship emission control area. Completed "based on remote sensing remote sensing of regional atmospheric pollutants monitoring technology for ships," based on the fuel exhaust of telemetry ship compliance rapid inspection technology "and" reverse recognition based on optimization and uncertainty of fuel compliance method determining and violations of ship identification method ", and "based on AIS data of ship tracking algorithm pollutants emission" such as the development of technology. The development of on-line monitoring equipment for ships is completed, which can measure the real-time emission concentration of nitrogen oxide, sulfur oxide, carbon dioxide, particulate matter and other pollutants in ship exhaust gas online. The developed equipment has passed the type certification of China classification society, which is the first batch of equipment that has obtained the type certification of ship exhaust test. At the same time, the ship emission on-line monitoring platform and the real ship test work will be carried out. A platform for monitoring air pollutants in the ship emission control area will be formed and demonstrated in the three emission control areas. It provides scientific and technological support for air pollution management in China's shipping industry. Through the implementation of the project, the project team has reported the ship emission control system to the Ministry of Transport, and made use of the project results to actively promote the improvement of the ship emission control system.
