Problems solved by technology

However, due to the influence of factors such as fishing boat trawling operations and ocean storms, the position of the submerged buoy may change greatly, which will bring great difficulties to the search for the submerged buoy, and even directly lead to recovery failure and system loss, resulting in huge economic losses. loss

Embodiment Construction

[0013] see figure 1 , the system structure is composed of a global positioning system (GPS) receiver installed on a search vessel, a deck unit of a hydroacoustic releaser, an integrated signal receiving and processing unit (stored in a computer in the form of a program), and a hydroacoustic system integrated in a submarine mark system. The underwater acoustic response system on the releaser is composed of a global positioning system (GPS) receiver, the underwater acoustic releaser deck unit, and the integrated signal receiving and processing unit to form the deck part, and the GPS receiver and the underwater acoustic releaser deck unit communicate with each other through the serial port. The computer realizes the communication connection, and the integrated signal receiving and processing program (main program) running in the computer controls and samples the external equipment; The ship moves along a triangular (or circular) trajectory and constantly instructs the submersible...

Abstract

The invention relates to submerged buoy automating hunting positioning system. It includes deck part formed by global positioning system receiver, water acoustic releaser deck unit, and synthesis signal reception processing unit, and water acoustic response system. Transducer is removed around triangle or circular trace to instruct submerged buoy system to transmit response signal to form virtual triangle or circular transducer array. The system is used global positioning system receiver to gain transducer space moving trace, and used submerged buoy response signal to measure its distance. They are gained to show submerged buoy system positional information. The invention combines locating information gained form GPS with water acoustic distance finding to realize submerged buoy system sqace orientation.

Description

technical field [0001] The invention relates to a ship-borne submarine buoy automatic search and positioning technology, in particular to a submerged buoy automatic search and positioning system combining GPS positioning and underwater acoustic ranging. Background technique [0002] As a self-contained, long-term, continuous and unattended observation system, the submersible buoy deployed in the observation waters has long been favored by the majority of marine scientific and technological workers. Since the system is deployed underwater and often integrates multiple precious measuring instruments, whether it can be recovered reliably becomes the primary issue to be considered when deploying the submersible buoy system. The positioning of the submerged mark is the basic premise to ensure the smooth recovery of the submerged mark system. For a long time, researchers from various countries have done a lot of research work on the positioning of underwater targets, and have suc...
