System for recovering, positioning and searching marine instrument

Abstract

An embodiment of the invention discloses a system for recovering, positioning and searching a marine instrument. The system comprises an instrument positioning module, a ship body positioning module, an instrument communication module, a ship body communication module and a data analysis module; the position of an instrument and the position of a ship body are determined by the positioning modules, and position information of the instrument is transmitted to the ship body by wireless communication modules for comparative analysis with position information of the ship body, so as to plan a route between the instrument and the ship body. By using the system, the problem of recovering, positioning and searching the marine instrument under the condition that marine equipment does not have global mobile communication is solved, accurate recovery of the marine instrument is realized, the searching efficiency of instruments is improved, the searching cost is saved, and the loss rate of instruments is reduced.

Description

technical field [0001] Embodiments of the present invention relate to electronic device positioning technology, and in particular to a maritime instrument recovery, positioning and searching system. Background technique [0002] With the development of modern economy and science and technology, more and more marine observation instruments are used, such as submarine seismometers, submarine acoustic wave observers, etc. The task of marine observation is to obtain information about the marine environment and resources, so as to contribute to marine scientific research and marine resources. development services. In the process of ocean exploration, it is necessary to put various instruments into the ocean to achieve the detection goal. Depending on the detection target, some of these instruments are installed on the seabed, and some are installed in seawater at different depths from the water surface. When the ocean exploration activities are over, these instruments will be r...

Problems solved by technology

[0003] Due to the vast sea surface, the instrument often deviates from the preset position under the action of the ocean current, which makes it difficult to search for the instrument; if there are multiple instruments that need to be recovered at the same time, this difficulty will be more obvious, often neglecting one another, and even losing the instrument. lead to major economic losses

[0004] However, in the prior art, the positioning of offshore instruments is different from the land positioning system. The land positioning system is realized through GPS and global mobile communication technology. First, the longitude and latitude of the instrument are obtained through GPS, and then sent to the host computer through GSM or WiFi for positioning search. However, most marine equipment does not have global mobile communication signals and global mobile communication is expensive, so the positioning system on land cannot be well applied to the positioning and search of marine instruments, so that the recovery and search of marine instruments cannot be completed well
