Problems solved by technology

[0005] What the present invention aims to solve is that the existing underwater acoustic beacons all adopt a single synchronous working mode, which requires synchronous processing before use, which is relatively complicated to use, and there is a risk of losing the synchronous signal and not working normally.

Abstract

The invention discloses an underwater acoustic beacon with multiple work modes, which is underwater equipment used for positioning and navigating an underwater target, is an important component of a long baseline, a short baseline, a super-short baseline acoustic positioning and navigation system and an underwater GPS positioning system. The invention mainly comprises a signal processing board, a battery connected with the signal processing board, a transducer and a pressure sensor. The invention has multi work modes, such as an external synchronization mode, an internal synchronization mode, an inquire response mode and a test mode.

Description

technical field [0001] The invention relates to an underwater acoustic device for underwater target positioning and navigation, in particular to an underwater acoustic beacon with multiple working modes. Background technique [0002] Today, the use of acoustic technology to realize the positioning and navigation functions of underwater targets is the main technical means. According to the size of the receiving array or the baseline length of the transponder array, the underwater acoustic positioning technology can be divided into three types: long baseline, short baseline and ultra-short baseline. The underwater acoustic beacon can be applied to the above three underwater acoustic positioning technologies. The underwater acoustic beacon is installed on the measured carrier, and the distance of the target is determined by measuring the time delay difference between the underwater target sound source and each array element, thereby Realize the positioning and navigation funct...
