Embodiment Construction

[0020] Embodiments of the present invention are described in detail below, and the embodiments are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0021] Such as figure 1 As shown in Fig. 1, a set of underwater wireless optical communication devices is installed on the underwater vehicle and the sensor node. When the two sets of underwater wireless optical communication devices are aligned, short-distance non-contact underwater wireless high-speed communication can be realized.

[0022] Each underwater wireless optical communication device is composed of a watertight housing, a light emitting and receiving lens, and a photoelectric conversion module. The optical communication band adopts the 1310nm infrared band, and the two-way communication adopts the physical separation method, and the distance is not greater than 10mm.

[0023] The watertight housing realizes the waterproofing of the whole device. ...

Abstract

The invention provides a low-cost infrared band underwater wireless optical communication device which is formed by a watertight casing, a light emitting and receiving lens and a photoelectric conversion module. The light emitting and receiving lens has a focusing lens and a fiber collimator inside, the optical fiber collimator is used to perform beam expansion when light is emitted, and the focusing lens is used to perform focusing when the light is received. The mutual conversion of an electrical signal and an optical signal can be achieved by the photoelectric conversion module which is formed by a standard infrared SFP optical module and a Gigabit photoelectric switch. The photoelectric conversion module is installed in the watertight casing, the standard infrared SFP optical module isflexibly connected to the optical transmitting and receiving lens through an optical fiber, and the Gigabit optical switch is connected to an external system through a Gigabit Ethernet interface. According to the low-cost infrared band underwater wireless optical communication device, the underwater close distance point-to-point high-speed wireless communication is achieved by using an infrared band spatial light signal, and the device has the advantages of small volume, low cost and high speed.

Description

technical field [0001] The invention relates to the technical field of underwater wireless communication, in particular to a low-cost infrared band underwater wireless optical communication device, which uses infrared band spatial light signals to realize underwater short-distance point-to-point high-speed wireless communication, and has the advantages of small size, low cost, and high speed. Outstanding advantages. Background technique [0002] At present, underwater wireless communication mainly includes: low-frequency electromagnetic wave communication, underwater acoustic communication and wireless optical communication. Low-frequency electromagnetic wave communication uses extremely low-frequency radio waves for underwater transmission of information. Its communication rate is extremely low, the communication distance is short, and the transceiver equipment is huge. Underwater acoustic communication is currently a relatively mature underwater wireless communication met...
