Embodiment Construction

[0042]The signal transmission process and transmission principle of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0043] like figure 1 As shown, the small-sized remote-control underwater robot common cable transmission system involved in the present invention includes an above-water module connected to a coaxial cable for transmitting radio frequency and alternating current, an underwater module and its power supply circuit, which can simultaneously realize one-way transmission of video signals, data Two-way half-duplex transmission of signals, one-way transmission of AC power.

[0044] The 110V50Hz AC power transmitted by the underwater module is coupled with the RF signal through the power coupler / separator, and then transmitted to the power coupler / separator of the underwater module through a coaxial cable, and is separated from the RF signal to supply power for various equipment of the under...

Abstract

The invention relates to a co-cable transmission device and method for a small remotely controlled underwater robot. The co-cable transmission device comprises a water module and an underwater module, and the water module and underwater module are connected through a transmission co-cable for transmitting radio frequency / alternating current power supply signals. The method includes that using a carrier technology to modulate video and data signals, after compounding with the alternating current power supply signals, realizing multi-signal transmission through a single-core coaxial cable. The co-cable transmission device for the small remotely controlled underwater robot comprises the water module and underwater module connected by the co-cable; the co-cable transmission device is low in cost, high in transmission quality, strong in anti-interference performance, capable of simultaneously transmitting power supply signals and two kinds of different radio frequency signals on the same cable, and suitable for the small remotely controlled underwater robot.

Description

technical field [0001] The invention relates to a small remote-controlled underwater robot common cable transmission device and method, which belongs to the technical field of video data power transmission and is applied to small remote-controlled underwater robots. Background technique [0002] Remotely controlled underwater robot (hereinafter referred to as ROV) is an unmanned submersible widely used in underwater observation operations. It is connected to the working mother ship through the umbilical cable. The mother ship provides power to the ROV through the umbilical cable and issues commands to control the movement of the ROV; The ROV transmits the data collected by various sensors, the working status data of the equipment, underwater images, and sonar signals to the mother ship through the umbilical cable, providing various necessary information for the ROV remote operator. Therefore, how to efficiently, reliably and stably transmit unidirectional video signals, bidi...
