Embodiment Construction
[0023] The invention provides a high-definition elevator special cable to make up for the lack of reliability of the elevator monitoring line in the prior art and the poor video quality caused by the use of analog signals. By introducing 8-core network data into the existing elevator monitoring line cable to transmit video digital signals, enhance anti-interference ability and significantly improve video quality; the use of tensile load-bearing rope effectively ensures that the high-definition elevator monitoring cable is not easy to be broken and prolongs its service life; power cord, network data cable, two tensile load-bearing The center of the rope cross-section is located on a center line of the cross-section of the sheath layer, and two tensile load-bearing ropes are symmetrically fixed on both sides of the sheath layer, and the power line and network data line are symmetrically fixed on the tensile load-bearing line through the sheath layer. Between the ropes, it ensures...

Abstract
The invention relates to a high-definition elevator monitoring cable and a manufacturing method thereof, comprising a power line (1) for transmitting power, a network data line (2) for transmitting digital signals, and two high-definition elevator monitoring lines respectively The tensile load-bearing rope (3) on both sides of the cable is used to bear the weight of the elevator line and play a role in tensile resistance, and the tensile load-bearing rope (3) wrapped on the power cable (1), the network data cable (2) and the tensile load-bearing rope (3) The outer sheath layer (4); the power line (1) and the network data line (2) are symmetrically fixed between the tensile load-bearing ropes (3) through the sheath layer (4) Between; the center of the cross-section of the power line (1), the network data line (2) and the tensile load-bearing rope (3) is located on the center line of the cross-section of the sheath layer (4). The invention provides a high-definition elevator monitoring cable which introduces digital signals, effectively resists interference, has a long service life, and is safe and reliable, and a manufacturing method thereof.
Description
technical field [0001] The invention relates to a cable, in particular to a high-definition monitoring cable for elevator monitoring and a manufacturing method thereof. Background technique [0002] As the main tool for carrying passengers and goods in high-rise buildings, elevators will be more and more widely used in the future. As the most common public place, the installation of surveillance cameras in elevators has become popular. Since there are video screen monitoring lines and power supply lines inside the elevator, in the elevator monitoring system, the elevator lines mainly include signal lines and power lines. [0003] The current elevator monitoring technology is to mix the video lines into the accompanying cables, use the nearby power supply as the connection point of the monitoring power line, and then connect the output of the elevator machine room to the monitoring center, which increases the difficulty of construction and low reliability. The elevator shaft...
