Embodiment 1

[0046] see figure 1 , this embodiment provides an underwater visible light communication transceiver module, including: a casing 100, one end of the casing 100 is provided with a group of visible light underwater transceiver modules 200, and the other end is connected to a remote communication device with a cable 300, and the visible light The underwater transceiver module 200 is electrically connected to the cable 300 .

[0047] It can be seen from the figure that the head of the housing 100 of this embodiment is in the shape of a bullet, the tail is provided with an empennage 101, and the outer wall of the housing 100 is provided with four sets of drainage channels 102 connected to the tail end of the housing 100. Each set of drainage channels One group of underwater propulsion device 103 is all installed in 102, see figure 2 . The structure of the housing 100 is conducive to underwater operations. Just put the underwater visible light communication transceiver module of ...

Embodiment 2

[0064] see Figure 4 , this embodiment provides an underwater visible light communication transceiver module, including: a housing 100, a group of visible light underwater transceiver modules 200 are arranged at both ends of the housing 100, and two groups of visible light underwater transceiver modules 200 pass through the housing 100 The transmission channel communication within the transmission channel may be wired transmission or wireless transmission. It can be seen from the figure that the two ends of this embodiment are bullet-shaped, and the chamber walls at the ends are made of light-transmitting material.

[0065] Such as Figure 5 As shown, the internal structure of this embodiment is similar to that of Embodiment 1, and the housing 100 is provided with a waterproof compartment 110. The difference is that the waterproof compartment 110 includes a power supply chamber 112 and two communication chambers 111, and the two communication chambers 111 are located in the c...

Embodiment 3

[0081] see Figure 6 , this embodiment provides an underwater visible light communication transceiver module, including: a housing 100, the housing 100 is constructed from two separable sub-bodies 120, and the ends of the two sub-bodies 120 are respectively provided with a group of visible light Underwater transceiver module 200. From Figure 6 It can be seen from the figure that the ends of the two sub-bodies 120 in this embodiment are bullet-shaped, and the chamber walls at the ends are made of light-transmitting material.

[0082] Such as Figure 6 , 7As shown, the contact surfaces of the two sub-body 120 are provided with construction parts, wherein the construction part of one sub-body 120 is a male head 121, and the construction part of the other sub-body 120 is a corresponding female head 122, and the two are matched to complete Construct;

[0083] Since the casing 100 is a structure that can be split into two sub-bodies 120, the communication mode between the sub-...

Abstract

The present invention is applicable to the technical field of visible light communication, and provides an underwater visible light communication transceiver module, including: a casing, at least one end of the casing is provided with at least one group of visible light underwater transceiver modules, and the visible light underwater transceiver module It includes a visible light underwater receiving unit and a visible light underwater sending unit, the optical paths of the visible light underwater receiving unit and the visible light underwater sending unit are both facing the outside of the housing and are independent of each other. In the embodiment of the present invention, by making the receiving unit and the sending unit independent of each other, the signal transmission of different optical paths can be processed separately, that is, different optical signals can be sent and received at the same time, and the signal sending and receiving of different data can be completed at the same time; underwater visible light communication transceiver The module is highly adaptable and can be arranged according to the needs of different scenarios. It can not only adapt to various underwater communication scenarios, but also change the optical path angle of visible light communication, and extend the communication distance by connecting multiple devices in series.

Description

technical field [0001] The invention belongs to the field of visible light communication, and in particular relates to an underwater visible light communication transceiver module. Background technique [0002] Visible light communication is a new type of information technology that uses the high-speed on-off response characteristics of LEDs to realize wireless transmission. Visible light communication has the technical advantages of high speed, no electromagnetic radiation, high density, low cost, rich spectrum and high confidentiality. Especially in December 2015, after being tested and certified by the Ministry of Industry and Information Technology of China, China's "Key Technology Research of Visible Light Communication System" made another major breakthrough, and the real-time communication rate has been increased to 50Gbps, which once again demonstrated the high-speed advantage of visible light in the communication field. [0003] Since radio waves cannot propagate un...
