Coaxial cable wideband transmit of described copper core and power supply subsystem comprise a pair of frequency divider, and both are connected with the coaxial cable 2 of copper core, and transmission range can reach myriametre, middle non-relay station; A pair of wideband transmit module, an end of each module is connected to the digital interface of frequency divider, and the other end is connected to the network interface of computer; A pair of power module, an end is connected to the power interface of frequency divider, and the other end is connected respectively to dc power supply output interface and underwater installation power input interface.
Described underwater digit color video acquisition process subsystem.Utilize computer technology, simulation (or the numeral) vision signal of gathering external video signal source under water becomes resolution and can reach 720 * 576 colour (or black and white) digital picture.Be compressed into video format.
Video shows and recording subsystem on the described ship, uses a computer to receive to gather compression under water and use the wideband transmit subsystem, is transferred to colour (or black and white) DID on deck through the coaxial cable of copper core.The back stack relevant information that decompresses is presented on the screen, is recorded in simultaneously on disk or the tape.
Described frequency divider adopts high pass filter and low pass filter combination, and the alternation of transmission of digital modulation weak electric signal and DC power supply provide 200V above direct current respectively.
Because the present invention has adopted armouring copper core coaxial cable, has substituted expensive optical cable, therefore, relative price is lower, and under the sea-floor relief complicated situation, its job security is also good than optical cable.
Have its resolution to reach as high as 720 * 576 coloured image again, distance can reach myriametre, middle non-relay station.Therefore, image is also clear, stable.
