Abstract

The invention discloses a ship tail gas signal automatic identification method suitable for a ship tail gas monitoring station. The method comprises the steps of defining a suitable meteorological condition of the ship tail gas monitoring station; automatically identifying an effective monitoring period; automatically calculating the background concentration of nitric oxide in the effective monitoring time period; and automatically identifying ship tail gas signals with nitric oxide concentration higher than air background concentration. According to the invention, through defining the effective monitoring range of the ship tail gas monitoring station, a series of automatic analysis is carried out on the measured monitoring data. The purpose of automatically identifying the ship tail gas signals can be achieved, the labor cost required for daily processing of a large amount of monitoring data and identification of the ship tail gas signals can be saved, the automation degree of operation of a ship tail gas monitoring station is improved, and the efficiency of ship tail gas monitoring and supervising in a ship emission control area is improved.

Description

technical field [0001] The invention relates to the field of ship tail gas signal monitoring, in particular to a ship tail gas signal automatic identification method suitable for a ship tail gas monitoring station. Background technique [0002] The ship exhaust monitoring station is a continuous air quality monitoring system built on the side of the waterway or on the overspan bridge. Or build a ship exhaust monitoring station on the upper-span bridge. By monitoring the emission characteristics of passing ships, it can identify violations such as illegal use of high-sulfur oil, intentional closure of exhaust after-treatment facilities, and deterioration of ship engines. Targeted supervision Provide monitoring data support. However, whether the ship exhaust monitoring station can monitor the ship exhaust is affected by the ship's tonnage, distance, wind speed and direction, etc. Most of the time the concentration of air pollutants monitored is the background concentration of...
