Problems solved by technology

The transceiver transducer is installed on the bottom or top of the deep-sea space station, and it cannot locate the moving target on the side of the deep-sea space station; if the transceiver transducer is installed directly in front, the deep-sea space station cannot move to the sides and rear Target positioning; if installed in all directions, it will cost a lot

Embodiment Construction

[0035] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

[0036] Such as figure 1 As shown, a kind of lateral measurement type inverted ultra-short baseline transceiving transducer of the present embodiment comprises a sound head 1, and multiple groups of sound arrays are installed at intervals on the side of the sound head 1, and an electronic cabin 2 is installed at the bottom of the sound head 1, An underwater platform 3 is installed at the bottom of the electronic cabin 2, and a controller module 23 is installed in the electronic cabin 2. The underwater platform 3 works under the control of the controller module 23, thereby driving the sound head 1 to rotate.

[0037] The structure of the sound head 1 is: a support body 11 comprising a cylindrical structure, a plurality of sound-transmitting rubbers 12 are evenly installed on the circumferential surface of the support body 11 along the circum...

Abstract

The invention relates to a lateral measurement type inverted ultra-short baseline transceiver transducer and its working method. Cloud platform: According to the strength of the acoustic signal fed back by multiple acoustic arrays and the azimuth signal of the underwater target, the signal processing module generates a rotation command, and the underwater platform is controlled by the controller module, and the rotating shaft is driven by driving the motor , so that the sound head rotates, so that the optimal area of ​​action of the transceiver transducer is aligned with the underwater target for accurate tracking and positioning. The invention effectively solves the problem of insufficient operating area of ​​the existing ultra-short baseline positioning system by installing multiple groups of acoustic arrays at intervals on the side of the sound head, realizes accurate positioning within the range of large lateral opening angles, and greatly expands its effective operation area, and the transceiver transducer can automatically rotate the sound head according to the actual situation for more accurate positioning, good applicability.

Description

technical field [0001] The invention relates to the technical field of underwater positioning, in particular to a lateral measurement type inverted ultra-short baseline transceiver transducer and its working method. Background technique [0002] The 21st century is the century of the ocean. The research, development and utilization of the ocean are inseparable from marine engineering equipment. The deep-sea space station has become the frontier of marine technology research in developed countries. The deep-sea space station is a kind of deep-sea transportation equipment that is not restricted by the harsh wind and wave environment on the sea surface, and can directly control operating tools and devices in the deep sea for a long period of time and all-weather, and carry out marine scientific research, resource exploration and development, and submarine engineering operations. For specific underwater tasks, the deep-sea space station is generally equipped with an operational ...
