An active-passive compatible underwater acoustic positioning system

Abstract

The present invention provides an active-passive compatible underwater acoustic positioning system, which includes 4 submersible locator networking equipment and 1 submersible locator positioning terminal; both the submersible locator networking equipment and the submersible locator positioning terminal include a submersible locator and a battery pack, so the The submersible mark is fixedly connected to the battery pack; the submersible mark includes an electronic cabin, a transceiver and combined underwater acoustic transducer and a depth gauge respectively located at both ends of the electronic cabin, and the transceiver combined underwater acoustic transducer is configured to transmit and receive 7- 11kHz underwater acoustic signal, and the depth gauge is configured to obtain the depth information of the submerged buoy; the submarine buoy networking equipment also includes a buoy. The present invention simultaneously satisfies the active positioning requirements when the underwater target autonomously emits sound and the passive positioning requirements when the underwater target does not emit sound simultaneously in one set of systems, adopts a variety of communication methods, and can meet the connectivity, economy, etc. between the system and the shore-based system. When deployed in the offshore, economical wireless communication can be used to communicate with the shore base; when deployed in the COSCO Sea, satellite communication can be used to communicate with the shore base.

Description

technical field [0001] The invention relates to the technical field of underwater acoustic positioning, in particular to an active-passive compatible underwater acoustic positioning system. Background technique [0002] In order to respond to the national strategy of "deep-sea entry, deep-sea exploration, and deep-sea development", and to solve the needs of active positioning of underwater UUVs and other targets and the passive positioning and navigation needs of our own underwater specific targets, it is necessary to develop an active and passive positioning system for underwater communication and navigation, and build a hundred square meters of deep sea. Kilometer-level underwater positioning, navigation and communication integrated networking system. SUMMARY OF THE INVENTION [0003] In order to meet the positioning requirements of multiple scenarios and the requirements for the shore-based system to reliably obtain the position information of underwater targets in diff...
