Embodiment Construction

[0030] like figure 1 , 2As shown, a shore-based all-laser ship exhaust remote sensing detection method includes a remote sensing main unit 15, a remote sensing auxiliary unit 16, and a detection auxiliary unit 17. The remote sensing main unit 15 and the remote sensing auxiliary unit 17 are respectively installed on both sides of the river, and the farthest installation distance is 500 meters, for real-time measurement of the ship exhaust plume in the river. The detection auxiliary machine 17 includes a host computer 10 and an auxiliary measurement unit 14, which can realize site management, access to real-time monitoring information of ship exhaust, historical information analysis of ship tail gas, snapshot of black smoke from ship tail gas, lock management of suspected ships, information management of illegal ships, The 8 functions of ship holographic map management and remote monitoring user information management can realize real-time acquisition of ship exhaust emission i...

Abstract

The invention discloses a shore-based full-laser ship tail gas remote sensing detection method, which strengthens basic theoretical research, system construction and related technical equipment research and development of ship tail gas emission control and treatment in China, reduces the gap with developed countries, strengthens the ship air pollution control and treatment capability in China, overcomes defects of supervision modes and means at the present stage, and enhances the ship tail gas monitoring capacity. According to the invention, a laser absorption spectrum technology is applied to research the emission flux of SO2, NO2, NO, CO2, CO and C3H8 in ship tail gas and a tail gas smoke intensity measurement method, and a full-laser ship tail gas remote sensing test platform system is integrally constructed. The tail gas remote sensing test platform system accesses ship tail gas monitoring result data of outfield equipment in real time through the ship tail gas remote sensing monitoring management platform, the result data comprise six-component concentration information, wind direction and wind speed parameters, AIS information of a corresponding ship, black smoke snapshot images and the like, and emission information of ship tail gas is obtained in real time without boarding a ship.

Description

technical field [0001] The invention relates to the technical field of tail gas detection, in particular to a shore-based all-laser ship tail gas remote sensing detection method. Background technique [0002] The "Air Pollution Prevention and Control Law" stipulates that "inland rivers and river-sea direct ships shall use ordinary diesel oil that meets the standards." Ship-related emission requirements". Ships that violate the regulations and use non-standard fuel oil will be punished by the maritime safety management agency according to their duties. Due to the rapid diffusion of exhaust gas, it is difficult to obtain evidence, and the traditional direct detection method is difficult to realize. Existing regulatory means enable the maritime department to initially have the ability to investigate and deal with excessive exhaust emissions, but they still cannot meet the current ecological and environmental protection needs and situation, and there are major shortcomings. T...
