Problems solved by technology

[0004] (1) There is no underwater acoustic communication and accident alarm device between the underwater operation equipment and the surface command ship or wharf control station, and it does not meet the requirements of modern ship inspections. Effective safety measures must be provided for the underwater operation of underwater operation equipment Require
[0005] (2) The underwater operation device has no underwater sound alarm working mode, and the occupants on the underwater operation device (including operating, management and sightseeing personnel) lack effective safety guarantee means. Acoustic alarm signal, so that no hydroacoustic guidance or positioning signal can be issued to search and rescue vessels
[0006] (3) The existing underwater acoustic communication equipment or underwater acoustic response device does not record in real time the voice of the operator of the underwater vehicle when the shipwreck occurs and the voice of the accident response, so that the post-event maritime analysis of the underwater operating device lacks an effective original audio recording
[0007] (4) The existing underwater acoustic communication equipment is bulky and not suitable for small underwater operation devices
[0008] (5) Existing underwater acoustic communication equipment or underwater acoustic response devices cannot work after the main power supply is cut off

Embodiment Construction

[0089] Fig. 1 and Fig. 2 show the principle schematic diagram of the underwater acoustic communication and alarm method and device configuration of the present invention. The water system navigation body and the surface command ship or dock control station must be equipped with underwater acoustic communication and alarm devices A and B using the same communication and alarm system and using water as the transmission medium. The underwater acoustic emission system A2 of device A transmits via the carrier frequency The modulated voice or telegraph or dual-frequency alarm coded signal is converted into an underwater acoustic carrier frequency signal through the underwater acoustic system A4 for electro-acoustic energy, transmitted through the water medium, and reaches the underwater acoustic system B4 of the device B for acoustic-electric conversion. The energy is converted into a carrier frequency electrical signal, sent to the underwater acoustic receiving system B3, and the re...

Abstract

This method and device are used for the underwater cabins, e.g. dived sightseeing submarine to comm. and wreck alarm (CWA) with the commending ship or the dock control station. This underwater audio CWA device possesses simple circuit, compact structure, reliability, and efficiency. It saves energy, costs low and is easy to miniaturize. It adopts sideband CWA mode, co-uses the receiving modulating and emitting demodulating circuits. It not only builds an underwater audio comm. channel, but also offers a wreck alarm channel. The audio alarm signal offers position info for the searching and succoring ships. This system is also equipped with a recorder with a waterproof and stress-durable shell. This recorder records and stores all CWA audio info of whole process to offer an original info for the happened wreck analyzing. These meet the requirement of the effective safety measure submitted by the modern ship verification and raises the safety of the underwater tasks.

Description

technical field [0001] The present invention relates to underwater acoustic communication and alarm signal transmission of ships operating in water, in particular to methods and devices for underwater acoustic communication and alarm, in particular to fully submersible sightseeing submarines, other submersibles or underwater operating devices The invention discloses a method and a device for communicating with a surface ship or a wharf command station and providing a crash alarm. technical background [0002] At present, there is a lack of effective communication and accident alarm methods and devices between underwater operating devices (such as fully submersible sightseeing submarines, submersibles, robotic fish) and surface ships or wharf command platforms, so that underwater operating devices and The safety of its occupants cannot be effectively guaranteed. Once the underwater operating device crashes underwater, it cannot send a disaster alarm signal to the surface ship...
