Problems solved by technology

[0003] The underwater acoustic transponder is an important part of the long-baseline underwater acoustic positioning and navigation system. However, due to factors such as pressure-resistant shells, transducer technology, and signal processing methods, domestically produced transponders generally have single functions and low underwater acoustic range. Short, poor controllability and other shortcomings

Abstract

The invention provides a new type intelligent deepwater responder which consists of: treatment of underwater sound unit 1, electrical source managing unit 2, outer interface 5, sound transducer 3, and arming mechanism 4. The treatment of underwater sound unit 1 includes: the sound part of the treatment of underwater sound processing 6 mounted on the bottom board 9, power amplifier part 7, and capacity part 8; the electrical source managing unit 2 includes: power panel 10 and battery 11, the power panel 10 connected with the battery 11 is connected with the power consumption units via the bottom board 9. The functions and characters of the invention are self-correction, self-check, self-emancipation, low-power consumption, withstanding high voltage, high reliability, easy-to-operate; it can be used to response the request signal of nautical transceiver, and receive, execute and answer some definite nautical remotely controlled commands and realize the locate and navigating function of the long-base-line system.

Description

(1) Technical field [0001] The invention relates to underwater acoustic measuring equipment, in particular to an underwater acoustic measuring equipment used for underwater target positioning and navigation. (2) Background technology [0002] As far as the current technology is concerned, underwater acoustic positioning technology is still the mainstream of underwater target positioning and navigation. More than three underwater acoustic transponders are arranged on the seabed to form a certain geometric shape. The coordinate position of each transponder (element) must be precisely measured. The distance between each element can be compared with the depth of the sea. The carrier to be measured is generally Located within the range where the transponder is deployed, by inquiring the transponder, measuring the delay or delay difference of the responding signal of the transponder to determine its own position, so as to realize the function of navigation and positioning. This i...
