CONSTITUTION:A diver has the small mode switch or the small keyboard 1, a modulator 2, a drive amplifier 3, etc., all of which are loaded on his arm as a transmission means, and has a preamplifier 6, a demodulator 7, a word and sound synthesizer 8, the bone conduction earphones 9, etc., as a reception means, and further has a circulator 4 to transmit and receive waves, a transducer 5, etc. Necessary words such as 'Watch out.' and 'Go up.' that mean signals between divers or between divers and ships are prepared beforehand, and code signals to mean the words are transmitted. On the reception side the word and sound synthesizer is provided, and corresponding words and sounds are synthesized by the synthesizer according to the transmitted code signals, led to the bone conduction earphones and reported to a receiving party.

Description

[Detailed Description of the Invention] The present invention relates to a portable underwater wireless communication device, more specifically, a portable underwater wireless communication device carried by a 5CUBA Diper, and used for communication between 5CUBA Dipers, or between a 5CUBA Diper and a ship on the sea. The present invention relates to a portable wireless communication device suitable for use in communication, etc.

Recently, there has been an increase in dangerous work under the sea due to ocean development, and among the divers engaged in work, 5
Daiper accounts for a large proportion. In addition, the number of 5-cuba dippers for leisure is rapidly increasing. however,
Currently, there is no means of communication between fellow Daipers or between Daipers and ships at sea, so a wireless means of communication is desperately needed from the standpoints of safety and work efficiency. Compared to the type of diving that involves wearing a diving suit and sending air from a ship at sea, the 5 Cuba Diper, who carries an air cylinder on his back and does not require a lifeline, essentially prefers wireless communication as the communication method. It is natural that this happens. Unlike in the air, electromagnetic waves and light cannot be used as communication means in water, and ultrasonic waves (or sound waves) are usually used as the wave motion.

When considering wireless communication using ultrasonic waves for the 5-Cuba Diaper, the following two technical issues can be considered.

(1) Establishment of a man-machine interface between humans and transmitting/receiving equipment. (Since he is holding a mouthpiece to inhale air from the cylinder, it is difficult to speak freely. Normal earphones cannot be used underwater.) (2) Echo distortion due to multiple reflections from the seabed and sea surface. Establish a communication method that eliminates interference between multiple groups and prevents interference between multiple groups.

As a means to address the above technical problem (1), conventional methods have been implemented that use a helmet that covers the entire head, supply air inside the helmet, and use a microphone near the lips and earphones near both ears. There is. Another method was to supply air to the face using a face mask that covers only the face rather than the entire head, and to use a lip microphone and bone conduction earphones.

However, in the former case, a helmet is required, which is bulky and inconvenient, and in the latter case, there is a risk of water entering through the gap between the mask and the face, making it impossible to move the jaw sufficiently. be. In any case,
This method was extremely dangerous because it caused fear in the diapers. Furthermore, there is no effective method for responding to the above-mentioned technical problem (2), and conventionally only AM or SSB-AM has been used using sound waves as the wave medium.

The present invention corresponds to the communication method of the 5CUBA Diaper, more specifically corresponds to the above technical problem (1), and relates to the transmission and reception of the Diaper.
In cuba diving.

As mentioned above, Daiper carries an air cylinder on his back and has a mouthpiece in his mouth to inhale the air supplied from the cylinder, so he cannot speak freely.

Therefore, as a conventional method, a helmet exclusively for the head or a face mask for the face has been used.

It was extremely inconvenient for Daiper to use and was not put to practical use.

Purpose The present invention was made in view of the above-mentioned circumstances.
In particular, the purpose of this invention is to provide an underwater wireless communication device that can be carried by 5CUBA Diapers and perform wireless communication with other 5CUBA Diapers or between 5CUBA Diapers and a ship.

Configuration In order to achieve the above object, the present invention has a small mode switch or a small keyboard at the sending end, a voice synthesizer and a bone conduction earphone at the receiving end, or a vibration pickup at the sending end. The device is characterized by having a word speech recognition device or mapping device, and a speech synthesizer and bone conduction earphones at the receiving end. Hereinafter, the present invention will be explained based on examples.

FIG. 1 is an electrical block diagram for explaining one embodiment of the present invention. In this embodiment, the dialer is equipped with a small mode switch worn on the arm etc. as a transmitting means in addition to normal equipment. Or it has a small keyboard 1, a modulator 2, a drive amplifier 3, etc., and also has a preamplifier 6 as a receiving means.
, demodulator 7, word speech synthesizer 8. It has a bone conduction earphone 9, etc., and further includes a circulator 4 for transmitting and receiving sound waves.
, transducer 5, etc. In addition, in Figure 1,
Although a single transducer is shown for transmitting and receiving, it is of course possible to provide separate transducers.

The present invention is a conventional 5-cube device that holds the mouthpiece in the mouth.
This is related to a wireless underwater communication device that is based on the a-diaper, but as mentioned above, it is difficult to move the jaw and lips sufficiently when the mouthpiece is inserted into the mouth to inhale air from the cylinder. Difficulty producing sounds using normal methods.

Therefore, in the present invention, "be careful" or "get up"
Prepare in advance the necessary types of words that mean signals between fellow Daipers or Daipers and ships, transmit a code signal that means the words by some method, and use a word speech synthesizer on the receiving side. According to the code signal sent, a synthesizer synthesizes the corresponding word sound, and sends it to the bone conduction earphone to inform the listener.

In this device, it is assumed that the code signal transmission section uses conventional AM transmission using ultrasonic waves or a sonic wave region.

FIG. 2 is an electrical block diagram for explaining another embodiment of the present invention.

As a transmitting means, a vibration pickup microphone 10 is attached to an appropriate part of the face (for example, the forehead or the lips) and the uttered voice is picked up. In this case, a speech recognition device or mapping device 11 is provided to recognize the unclear word speech uttered by the dialer, and modulate the code of the recognition result with the modulator 2 and transmit it. In this case, the word speech recognition device prepares an ambiguous utterance for each word as a standard pattern and compares it. When using mapping, without actually uttering the word sounds, a predetermined code sound that is easy to pronounce and distinguish is uttered corresponding to each word, and the mapping device identifies this and converts it into a normal word. It converts the signal and transmits the code signal.

effect As is clear from the above description, according to the present invention, (a) by comprising a wireless communication device.

It becomes possible to communicate with fellow Diapers or between the Diaper and the ship, which helps improve the efficiency of danger prevention work. Also, in the case of leisure diving.

The fun increases through communication between fellow die-hards.

(b) Since you can use the normal 5 Cuba diving method, there is no danger and there is no fear of divers, so you can use it without feeling strange.

There are advantages such as
