Wireless communication transmits information between the robot and controller. However, the inherent high latency, high loss, and limited transmission distance of wireless communication severely restrict the potential of tethered robots for wider applications.

BRIEF DESCRIPTION OF THE DRAWINGS
[0017] Figure 1 It is a schematic diagram of the cable structure;
[0018] Figure 2 yes Figure 1 One of the cross-sectional structural diagrams;
[0019] Figure 3 yes Figure 1 The second schematic diagram of the cross-sectional structure.
[0020] In the figure, there are a signal label 100 , a separating insulating sleeve 101 , a power supply portion 102 , and a shielding layer 103 . DETAILED DESCRIPTION
[0021] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0022] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.
[0023] like Figure 1-Figure 3 As shown, a power supply signal cable includes:
[0024] a signal tag group comprising a plurality of signal tags 100 arranged in series;
[0025] A separation insulating sleeve 101, wherein a signal tag group is disposed in the separation insulating sleeve 101, and the signal tag group is used for signal reading by a reader / writer in the flying wire robot;
[0026] The power supply part 102 is located on the outer wall of the separating insulating sleeve 101 , and is used to supply power to the flying wire robot.
[0027] In this embodiment, by arranging the power supply part 102 outside the signal tag 100 group, while maintaining the normal power supply function of the cable, the power supply cable is also capable of carrying data and location information of the travel point; not only does it significantly reduce the delay and loss of information transmission, but it also greatly expands the operating radius of the flying wire robot, enabling it to perform tasks efficiently and accurately at a longer distance; in addition, a separating insulating sleeve 101 is provided between the signal tag group and the power supply part 102, and the separating insulating sleeve 101 plays an electrical insulating role.
[0028] It is worth mentioning that the signal tag 100 group carries the data, position and other information signals of each travel point, and is composed of multiple signal tags 100 connected in series. When the signal reader on the zipline robot is close to the signal tag 100, the reader will transmit a signal. This signal will form an electromagnetic field in space. When the signal tag 100 receives this signal, its load modulation module will reflect the signal transmitted by the reader and perform amplitude modulation during reflection, so that it contains the travel point data, position and other information in the tag. After the reader receives the signal reflected back by the signal tag 100, it extracts and processes it. Finally, the reader will transmit this information to the background system for processing or application. Preferably, the signal tag 100 group can use a radio frequency tag group. Using a reader to read the radio frequency signal is a technical means that can be implemented by those skilled in the art and will not be elaborated here.
[0029] Preferably, a shielding layer 103 is also provided on the separating insulating sleeve 101, and the shielding layer 103 is located between the power supply part 102 and the separating insulating sleeve 101. Because the distance between the reader and the cable on the robot is very close, the existence of the shielding layer 103 can shield some interference signals at a longer distance. Although the reading and writing signals of the reader will also be shielded, they can still pass through the shielding layer for signal transmission due to the short distance.
[0030] It is worth mentioning that the shielding layer 103 includes a corrugated copper tube, which has high mechanical strength and can withstand a certain external force and pressure, thereby ensuring the stability and durability of the shielding layer 103.
[0031] Specifically, the corrugated copper tube is provided with spiral patterns with a pitch of 3.5-3.9 mm, which increases the surface area and improves the reflection and absorption efficiency of electromagnetic waves, thereby achieving a better shielding effect.
[0032] It is worth mentioning that the steps for processing copper tubes include:
[0033] S1. Select oxygen-free copper tubes or high-purity copper tubes as raw materials, clean them and inspect their surfaces;
[0034] S2. Then the selected copper tube is heated to 400-600℃ and annealed to enhance the plasticity and toughness of the copper tube;
[0035] S3, using a corrugating machine to roll the copper tube to form a spiral pattern with a pitch of 3.5-3.9 mm;
[0036] S4. Ensure the standardization of copper tube size and shape through shaping molds and straightening machines;
[0037] S5. Remove burrs, polish or apply protective layer to enhance corrosion resistance and aesthetics;
[0038] S6. Sliding the preformed corrugated copper tube sheath onto the outer layer of the cable;
[0039] S7. After the corrugated copper tube sheath is coated, it is shaped so that the corrugated copper tube sheath fits tightly with the separating insulating sleeve 101 to achieve the required shape and size.
[0040] Specifically, the material of the separating insulating sleeve 101 includes polytetrafluoroethylene, which has excellent electrical insulation properties and can effectively isolate current and voltage to ensure the safe operation of electrical equipment. Secondly, polytetrafluoroethylene has low dielectric constant and loss characteristics. Its unique porous structure can minimize the loss and distortion during signal transmission, which helps to improve the efficiency and stability of signal transmission.
[0041] Preferably, the power supply unit 102 includes conductive wires, which are wound around the shielding layer 103 . The conductive wires include copper wires, and stainless steel wires are twisted on the copper wires to increase their strength. The copper wires and the stainless steel wires are twisted and then wound around the shielding layer 103 .
[0042] A flying cable robot comprises the above-mentioned power supply signal cable and a robot body. A reader / writer is provided on the robot body, and the reader / writer is communicatively connected to a signal tag group in the power supply signal cable.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.
