Example Embodiment

[0037] Example 1:

[0038] Such as figure 1 As shown, the ocean tow ocean tow coaxial cable and photoelectric composite cable dual-mode transmission device of this embodiment is composed of a water unit and an underwater unit, and the water unit and the underwater unit communicate through a coaxial cable or a photoelectric composite cable. And power supply, the dual-mode transmission device of the present invention can adapt to two working modes of ship-borne coaxial towing cable and photoelectric composite towing cable, and the two working modes do not need to be reconnected to the joint.

[0039] The water unit includes a first modem 2, a first hybrid transmission module 3, a 100M optical fiber transceiver 6, a first switch 7, a coaxial connector 8, an optical fiber connector 9, an aviation socket 4, a network socket 5 and a power supply module 1. Among them, the network socket 5 is connected to the first switch 7. The first switch 7 is also connected to the first modem 2 and th...

Abstract

The invention relates to an ocean drag coaxial cable and photoelectric composite cable double-mode transmission device and method. The device comprises an overwater unit and an underwater unit. The power supply and communication of the overwater unit and the underwater unit can be carried out through a coaxial cable or a photoelectric composite cable. The overwater unit comprises a first modem, a first hybrid transmission module, a first 100M fiber transceiver, a first switch, a coaxial joint, a fiber joint, an aerial socket, a network socket and a power supply module. The underwater unit comprises a second modem, a second hybrid transmission module, a second 100M fiber transceiver, a second switch, a first watertight socket, a second watertight socket, a photoelectric composite cable watertight socket, and a power conversion module. According to the device and the method, the power supply and communication of the overwater unit and the underwater unit can be realized, underwater equipment is suitable for coaxial cable and photoelectric composite cable double-mode working, the application scene of the underwater equipment is expanded, the switching of the coaxial cable and the photoelectric composite cable is reduced, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the fields of marine underwater scientific research and underwater towed detection engineering, in particular to a dual-mode transmission device and method of a marine towed coaxial cable and a photoelectric composite cable. Background technique [0002] In marine scientific research and marine engineering operations, unmanned underwater equipment with cables is often used, such as cable-controlled underwater robot ROV, integrated camera tow body, acoustic tow body, TV grab, TV multi-tube, CTD acquisition Water tanks, etc., underwater equipment should be controlled by the deck unit on the ship to complete the underwater operations, and the large-scale movement of underwater equipment is towed by the mother ship through the ship-borne tow cable. Underwater equipment is usually equipped with various instruments and equipment, which consumes electric energy. At the same time, it must transmit data to the deck unit in time and rece...
