Description
Technical field
The present invention relates to domain of communication equipment, more particularly to a kind of underwater bi-pass communication device.
Background technology
At present, as lake, river, ocean underwater inspection are with salvaging being on the increase for task, diver's underwater operation skill
Art is also constantly developing with diving equipment, can carry out subsurface communication and the very high novel submerged dress of safety and reliability
Tool is also more and more used by diver, and diver is when carrying out underwater operation, particularly engineering construction operation under water
In the process, it needs to cooperate between diver, particularly in the diving operation for needing mutually to assist, underwater cooperation needs the water surface
Diving superintendent mutually transmits the term of diver to complete, and during needing to transmit a large amount of terms, often waits one second and dives under water
Member's life security will mostly a danger, ensure the safety of diver, for underwater project construction be one put on the first place ask
Topic, and operating efficiency is improved, it is to improve the effective way of underwater operation safety to shorten operation construction period.Therefore, diver is underwater
The effect of the communication technology, particularly complex environment and special engineering is highly important to the life security for ensureing diver.
Currently, the communication of Underwater Engineering diver is mainly completed by diving telephone, but existing diving electricity
Words can only realize single communication, both communicating with each other between water surface commander and diver.Each corresponding one of diving commander is latent
Water person, existing diving telephone substantially meets demand during single-character given name diver's individual work, but if Underwater Engineering requires diver's phase
During mutual coordinating operation, " term " first need to be passed to water surface diving superintendent, then passed by diving superintendent by diver by diving telephone
Another diving superintendent is passed, then another diver is passed to by diving telephone and reaches a cooperation acted.
During coordinating operation, since " term " pipeline is more, operating efficiency and diver are leveraged
Underwater exposure duration increases security risk, and cannot carry out more complicated operation, needless to say some needs are mutually in step
The work that can be completed.
In face of this case, development underwater bi-pass diving telephone is a urgent job and improves diving operation effect
Rate and the important development direction for reducing security risk.
