Range finding method and system for dangerous material container falling into water

Abstract

The invention discloses a range finding method and system for a dangerous material container falling into water. The system comprises at least three detection nodes placed on the water surface of an area to be detected and capable of sending submarine sound signals of positioning commands to the dangerous material container falling into water; the detection nodes comprises a primary detection node, a secondary detection node and a water sound localizer beacon which is mounted on the dangerous material container; the primary detection node and the secondary detection node respectively obtain corresponding position coordinates; the water sound localizer beacon can receive the submarine sound signals of positioning commands and can send positioning response signals. The invention provides the range finding method for the dangerous material container falling into water, distance information needed for positioning can be obtained with a small number of water sound communication frequencies between the water surface detection nodes and the localizer beacon of the container, and defects of low efficiency, low energy saving effects and the like in conventional detecting and positioning technologies for the dangerous material container falling into water and the range finding method employing the same based on water sound signals can be overcome.

Description

technical field [0001] The invention relates to a distance measurement technology for containers of dangerous goods that have fallen into the water, in particular to a method and system for detecting and locating dangerous goods that have fallen into the water by processing underwater acoustic signals. Background technique [0002] In the process of transporting dangerous goods by water in containers, due to adverse weather conditions, unfavorable channel conditions, dense ship traffic flow distribution, and operational errors by ship drivers, accidents of dangerous goods containers falling into the water often occur. In order to avoid adverse effects of dangerous goods on navigation safety and the ecological environment, it is necessary to promptly salvage the dangerous goods containers that have fallen into the water. The detection and positioning of the falling container is the premise of the salvage work. The dangerous goods container detection and positioning technology...
