Super-flexible intelligent-control photoelectric composite cable for high-speed video transmission

Abstract

The invention discloses a super-flexible intelligent-control photoelectric composite cable for high-speed video transmission. The super-flexible intelligent-control photoelectric composite cable for high-speed video transmission can simultaneously meet the requirements of video signal transmission, control signal transmission and electricity energy supplying; the composite cable comprises opticalunits, electric units, data lines, a reinforcing core, and a cable core; a bending loss insensitive tight-buffered optical fiber serves as an optical fiber, the surface of the optical fiber is wrappedwith a nylon tight-buffered layer in an extruded mode, the exterior of the nylon tight-buffered layer is reinforced through water blocking aramid, and the exterior of the water blocking aramid is wrapped with an optical fiber protecting bush in an extruded mode; tinned copper stranded conductors serve as conductors, and the surfaces of the electric unit conductors are wrapped with crosslinked polyethylene insulation materials in an extruded mode; the data lines adopt bare copper stranded conductors, and the surfaces of the data line conductors are wrapped with high-density polyethylene insulating materials in an extruded mode; the reinforcing core adopts vertically-placed aramid yarn, and the surface of the aramid yarn is wrapped with a reinforcing core protecting sleeve in an extruded mode; the cable core comprises the two optical units, the four electric units, the two data lines and the reinforcing core, the center of the reinforcing core is vertically placed, and the two optical units, the four electric units and the two data lines surround the reinforcing core; and the cable core is externally provided with a wrapping tape, a shielding part and an outer protecting sleeve in sequence.

Description

technical field [0001] The invention relates to an ultra-flexible intelligent control photoelectric hybrid cable for high-speed video transmission Background technique [0002] In the process of film and television production, cameras need to be used. Cameras are mainly used for video recording. Since high-definition image pixels are high, the transmission capacity of transmission cables is required to be large; film and television recording requires uninterrupted power supply, so it is necessary to connect the power cord Intermittent power supply; In addition, a separate intercom system needs to be configured for real-time voice communication. At the same time, these cables also need to be bent repeatedly with a small radius according to the complex environment of video recording. [0003] In order to meet the above requirements, the high-definition video transmission line in the camera cable currently uses a separate optical cable for transmission; the power line uses a s...

AI Technical Summary

Problems solved by technology

[0004] 1. Optical cables and power cables are independent units, which are inserted into the camera separately. There are many cables inserted, which is not convenient for the camera to move back and forth.

[0005] 2. The existing cables cannot perform a low-voltage safety test on the equipment, and cannot monitor whether the equipment is in good condition

[0006] 3. The existing scheme cannot monitor the power line in real time, and it is easy to cause harm to people when there is a leakage

[0007] 4. Existing solutions require the use of external equipment (such as walkie-talkies) for real-time communication and transmission of information
