Ship emission detection method and system based on flight platform

Abstract

The invention provides a ship emission detection method and system based on a flight platform. The detection method comprises the following steps of providing a multi-rotor unmanned aerial vehicle, wherein the unmanned aerial vehicle is installed with an infrared camera, a laser range finder and a gas sensor module; making the infrared camera scan a ship, and determining a chimney position of thetarget ship and a direction of emitted smoke plume according to a scanned image; making the laser range finder measure a flight separation distance between the unmanned aerial vehicle and a ship chimney, and controlling the flight of the unmanned aerial vehicle according to the flight separation distance; and making the gas sensor module measure a gas pollutant concentration of the emitted smoke plume in real time, and determining whether ship emission is qualified according to the gas pollutant concentration. The detection system comprises the multi-rotor unmanned aerial vehicle and a groundcontrol center. By using the ship emission detection method and system, fast on-line detection of non-contact ship emission is realized, and the method and the system are efficient and reliable, and have good technical effects.

Description

technical field [0001] The invention relates to the technical field of ship emission detection, in particular to a method and system for detecting ship emission based on a flying platform. Background technique [0002] Exhaust gas emitted by ships traveling at sea is an important source of air pollution, and the use of low-quality dyes with high sulfur content has aggravated the problem of air pollution caused by ships. Traditional ship emission detection devices mainly include laser radar, fixed sniffer, portable gas analyzer, etc. However, due to their own technical characteristics, traditional detection devices have limitations that cannot be ignored. For example, lidar cannot realize simultaneous detection of carbon and sulfur, the detection structure of fixed sniffer is easily affected by the detection distance, portable gas The measuring instrument requires boarding a ship for close-range measurement, which greatly reduces the detection efficiency. For ports with a l...
