Abstract

The invention provides an array digital analogy integrated signal cable for an offshore oil platform underwater pre-warning system, and relates to the technical field of offshore oil platforms or underwater security and protection facility array signal cables. The array digital analogy integrated signal cable is an integrated cable with strong current analog and digital signals and weak current analog and digital signals in a mixed mode. The array digital analogy integrated signal cable comprises a center reinforcing unit, a seven-core cable unit, a five-core cable unit, a main woven shielding layer, a coaxial-cable unit, an inner protection layer, an armor layer and an outer protection layer. The center reinforcing unit or the coaxial-cable unit is internally provided with optical fibers for transmitting optical signals. The seven-core cable unit is arranged outside the center reinforcing unit, the five-core cable unit and the coaxial-cable unit are arranged outside the seven-core cable unit, the main woven shielding layer is arranged outside the five-core cable unit and the coaxial-cable unit, the inner protection layer is arranged outside the main woven shielding layer, the armor layer is arranged outside the inner protection layer, and the outer protection layer is arranged outside the armor layer.

Description

technical field [0001] The present invention relates to the technical field of array signal cables for offshore oil platforms or underwater security facilities, and is a combination of strong and weak current analog and digital signals. The integrated cable used; the matrix digital-analog integrated signal cable is used to transmit sonar sensor signals, magnetic compass sensor signals, power supply signals, shielding and lightning protection and other sensor signal processing for offshore oil platform early warning systems, and can also be widely used in complex The security needs of complex environmental systems such as waterways, military areas, engineering operations, and anti-theft. Background technique [0002] my country has a coastline of 18,000km, four sea areas including the Bohai Sea, the Yellow Sea, the East China Sea, and the South China Sea. It has numerous oil platforms and offshore facilities. The safety of offshore oil platforms is related to the country's ec...
