Example Embodiment

[0044] Embodiment 1, refer to the attached figure 1 , a handle 8 is fixedly connected to the surface of the signal transmitting unit 5 . The handle 8 facilitates the user to carry the signal transmitting unit 5 and transmit visible light signals.

Example Embodiment

[0045] Embodiment 2, refer to the attached image 3, a wristband 9 is fixedly connected below the signal sending unit 5 . The wristband 9 enables the user to wear the signal transmitting unit 5 on the wrist, so as to free up the hand to carry other devices and facilitate the transmission of visible light signals.

[0046] The present invention also provides a method for transmitting data signals underwater using an underwater communication device using visible light, which specifically includes the following steps:

[0047] Step 1: Set the LED driving unit 502 to the automatic mode or the communication mode;

[0048] Step 2: input the data signal into the input unit 4 underwater, and convert the data signal into an electrical signal through the input unit 4;

[0049] Step 3: adjust the amplitude of the electrical signal through the signal amplitude adjustment unit 501;

[0050] Step 4: generating an illumination signal in the LED driving unit 502;

[0051] Step 5: in the s...

Abstract

The invention discloses underwater communication equipment using visible light. The equipment comprises an oxygen mask, a signal receiving unit is installed at the top of the oxygen mask, output unitsare fixedly installed on the two sides of the oxygen mask, an input unit is fixedly installed at the front end of the oxygen mask, the input unit is connected with a signal sending unit through a cable, and an LED illuminating lamp is fixedly installed in the signal sending unit. Defects in the prior art are overcome, and the LED illuminating lamp is used for generating illuminating signals for communication, so that the data transmission speed is increased; The underwater environment is less interfered by visible light, and compared with the prior art, the LED illuminating lamp is adopted for underwater communication, so that the cost is lower; By arranging the filter unit, the error bandwidth of the electric signal which is mistakenly received in the transmission process can be removed;And moreover, the LED illuminating lamp is used for communication, so that broadband communication can be performed, and the safety of signal transmission is improved.

Description

technical field [0001] The invention relates to the technical field of underwater communication, in particular to an underwater communication device using visible light and a usage method thereof. Background technique [0002] In recent years, with the continuous deepening of ocean exploration, the requirements for underwater wireless communication technology have become higher and higher; usually as underwater wireless communication, there are fish detectors, deep-sea detectors and sonar detectors. Recently, the use of ultrasonic waves to perform underwater wireless communication has also been developed. [0003] In the prior art, a device that can improve the efficiency of information transmission by increasing the transmission efficiency in underwater wireless communication by minimizing the interference of multipath signals generated underwater provides effective information transmission. However, in the existing In technology, because the signal is only transmitted thr...
