Description
Technical Field
The present invention relates to IOT-based cables for use in cable management systems, and more particularly, to an IOT-based cable for use in a cable management system that facilitates managing the status and longevity of the cable.
Background
With the acceleration of the fourth industrial revolution, IT enterprises, typically google, microsoft, apple, tesla, soft silver, etc., are also pushing the fourth industrial revolution. These IT enterprises are also expanding industries in the power market, and along with this trend, the application of digital technology to the power market mainly based on analog technology is also expanding.
Therefore, the digital technology is also applied to the fields of power generation, power transmission and transformation, power distribution and the like, and state diagnosis of turbines and generators, development of component management solutions, fault judgment of cable systems, replacement level estimation, development of sensor embedded junction boxes, analysis of gas modes in transformer oil, and optimization and recovery systems of substations based on artificial intelligence are under development. In particular, techniques capable of visually confirming operation and state information of the cable are being developed, and information such as product quality, state diagnosis, and replacement cycle is provided based on these techniques.
However, these techniques are used by attaching or inserting a sensor or an identifiable element such as an RF-ID chip inside the cable, or attaching a sticker printed with an identifiable pattern such as a two-dimensional code to the outside of the cable. In these techniques, the manner of attaching the sensor or identifiable element inside the cable presents problems in that the cable is costly to manufacture and affects the cable's structural and electrical stability. Further, in the method of sticking stickers, since stickers are easily damaged by scratches and the like during distribution, construction, and management, and stickers having patterns corresponding to different binary codes cannot be stuck to each cable unit length, there is a problem that other information cannot be inputted when the cable wound on one reel is cut into unit lengths and sold or laid to different places during distribution and construction.
Disclosure of Invention
Problems to be solved by the invention
Accordingly, the technical problem of the present invention has been conceived in view of this aspect, and it is an object of the present invention to provide an IOT-based cable that can be used in a cable management system that can facilitate management of the cable by confirming the state of the cable, etc. in the field.
Technical scheme for solving problems
In order to achieve the above object of the present invention, a cable of an embodiment includes a cable core and a cable outer covering formed outside the cable core, having a pattern corresponding to a binary code on an outer surface of the cable outer covering.
In an embodiment of the present invention, the cable core may include a conductor layer and an insulating layer covering the conductor layer.
In an embodiment of the present invention, a plurality of patterns corresponding to binary codes are provided, and the central angles formed by the plurality of patterns corresponding to binary codes may be the same in the cross-sectional view.
In an embodiment of the present invention, a length of the pattern corresponding to the binary code in the longitudinal direction is represented as an arc length of a circle in a cross-sectional view, and a size of a central angle corresponding to the arc length may be 5 degrees or more and 15 degrees or less.
In an embodiment of the present invention, the length of the pattern corresponding to the binary code in the longitudinal direction is represented as an arc length of a circle in a sectional view, and the arc length may be 4mm or more and a length defined by the following equation or less.
h＝2πr x 15/360
(wherein h represents an arc length, and r represents a radius of the cable in a cross-sectional view.)
In an embodiment of the present invention, a ratio of a width of the pattern corresponding to the binary code in the longitudinal direction to a width in the transverse direction may be set to 1:2 to 1: 4.
Effects of the invention
According to the present invention, a pattern corresponding to a binary code is printed on a cable, and a recognition device and a platform corresponding to the pattern of the binary code are used at a manufacturing stage, a circulation/construction stage, and a field use stage, thereby enabling direct confirmation of required information.
In addition, when the information related to the cable needs to be changed, the changed information can be additionally input or the input information can be modified, thereby facilitating the management of the cable.
In addition, since information generated during the management of the cable is input in real time, and thus information omission does not occur, it is possible to prevent accidents caused by an inability to determine whether the cable is erroneously connected or electrified or not in the field.
In addition, by adjusting the widths of the patterns corresponding to the binary codes printed on the cable in the longitudinal and transverse directions, the recognition rate is improved, and the problem of a decrease in the productivity of the cable can be prevented.
In addition, by providing a plurality of patterns corresponding to binary codes printed on the cable, even when the cable is buried in the ground or is in contact with a facility and thus the patterns corresponding to a part of the binary patterns are not exposed, it is possible to prevent the unrecognizability by exposing the patterns corresponding to other binary patterns.

Fig. 5 is a diagram illustrating a pattern corresponding to a binary code disposed on an outer cladding of a cable management system according to an embodiment of the present invention. Fig. 6 is a diagram illustrating a pattern corresponding to a binary code disposed on an outer cladding of a cable management system according to an embodiment of the present invention. Fig. 7 is a diagram illustrating a pattern corresponding to a binary code disposed on an outer cladding of a cable management system according to an embodiment of the present invention. Fig. 8 is a diagram illustrating a pattern corresponding to a binary code disposed on an outer cladding of a cable management system according to an embodiment of the present invention.
Referring to fig. 5 to 8, the pattern corresponding to the binary code provided on the outer covering of the cable management system according to an embodiment of the present invention may have various forms. For example, the pattern corresponding to the binary code may be a dot matrix pattern, a two-dimensional code, or a data matrix.
The pattern corresponding to the binary code provided on the outer covering of said cable 400 may be printed during the manufacturing process of the cable. The manufacturing process of the cable is performed as a continuous manufacturing process wound on a reel after the production of the cable, and a pattern corresponding to a binary code may be printed on the surface of the cable along the length direction D3 of the cable after the process of providing the cable outer covering. Accordingly, the pattern corresponding to the binary code may be printed to have a width in a lengthwise direction D3, i.e., a transverse direction D1, of the cable and a width in a longitudinal direction D2 perpendicular to the transverse direction D1.
Therefore, in the continuous manufacturing process, the printing of the pattern corresponding to the binary code in the lengthwise direction D3 of the cable, i.e., the transverse direction D1, is not particularly limited, but in the case of the pattern corresponding to the binary code in the longitudinal direction D2 perpendicular to the transverse direction D1, it may be affected by the outer diameter of the cable or may affect the line speed performed during the continuous manufacturing process of the cable.
In addition, in the continuous manufacturing process, when the dot spacing in the longitudinal direction of the cable, i.e., the transverse direction D1, is increased by 20% or more (where the dot spacing in the vertical direction, i.e., the transverse direction, is constant) due to an increase in the linear velocity, the recognition rate is decreased to 25% or less, and when the dot spacing is increased by 15% to 19% (where the dot spacing in the vertical direction, i.e., the longitudinal direction D2, of the transverse direction D1, is constant), the recognition rate is decreased to 50% or less. Therefore, in order to control this, it is necessary to appropriately design the speed at which the cable passes and the printing speed of the dot pattern in the continuous manufacturing process of the cable.
The dot matrix pattern refers to a dot group composed of individual dots of a square or rectangle as shown in fig. 5 to 7.
The recognition rate is a percentage of reading information contained in a dot pattern by recognizing the dot pattern printed on the surface of the cable through the execution of the stage by the manufacturer terminal, the circulation/construction company terminal, or the user terminal and connecting to the manufacturer control part, the circulation/construction company control part, or the user control part.
Therefore, the dot matrix pattern printed on the surface of the cable 400 needs to be appropriately set in consideration of the relationship between the cable diameter and the number of dots arranged in the longitudinal direction, and in order to maintain the dot interval in the transverse direction, the cable advancing speed needs to be controlled according to the printing speed.
Fig. 9 is a cross-sectional view of a cable of the cable management system illustrating one embodiment of the present invention.
Referring to fig. 8 and 9, a cable 400 of a cable management system according to an embodiment of the present invention may include a conductor layer 410, an insulation layer 420, an outer cladding layer 430, and a pattern 440 corresponding to a binary code.
Since the cross-section of the cable 400 is formed in a circular shape, the length of the pattern 440 corresponding to the binary code provided on the outer cladding 430 of the cable 400 in the longitudinal direction D2 may be represented as an arc length h in a cross-sectional view. The length of the pattern 440 corresponding to the binary code in the longitudinal direction D2 may determine the central angle θ on the cross-sectional view of the cable 400. Accordingly, the length of the pattern 440 corresponding to the binary code in the longitudinal direction D2 may have different values according to the radius r and the central angle θ of the cable.
If the width of the pattern corresponding to the binary code in the longitudinal direction D2 is printed too wide, the process line speed may be slow in the cable manufacturing process as a continuous process, thereby possibly affecting productivity, and there is a problem in that accurate scanning cannot be performed due to the curved surface-shaped cable surface. In addition, when the width in the longitudinal direction D2 is printed too short, a problem of a decrease in the recognition rate may occur.
At this time, when the central angle θ is less than 5 degrees, the scanning recognition cannot be performed, and when the central angle exceeds 15 degrees, a problem of a decrease in linear velocity may occur in the continuous manufacturing process of the cable. Accordingly, the length of the pattern 440 corresponding to the binary code in the longitudinal direction D2 may be expressed as an arc length h having a central angle of 5 degrees or more and 15 degrees or less in a cross-sectional view of the cable 400.
The size of the central angle occupied by the pattern corresponding to the binary code in the cross-sectional view of the cable and the linear velocity of the cable in the continuous manufacturing process of an embodiment of the present invention may have values as shown in table 1 below.
[ TABLE 1 ]
| Central angle on cross-sectional view of |
Line speed of cable in continuous manufacturing process |
| 5 to 15 DEG | 20～50mpm |
| 16 to 32 |
1～19mpm |
In addition, when the arc length h is less than 4mm regardless of the radius r of the cable 400, it cannot be recognized by the terminal scan. That is, the terminal can recognize the pattern corresponding to the binary code only when the length of the pattern corresponding to the binary code in the longitudinal direction D2 is at least 4mm or more. Accordingly, the arc length h of the pattern 440 corresponding to the binary code represented on the cross-sectional view of the cable may have a value of 4mm or more and a length defined by equation 1 below or less.
h＝2πr x 15/360
(wherein h represents an arc length, and r represents a radius of the cable in a cross-sectional view.)
At this time, the unit of the arc length and the radius of the cable may be mm. However, the present invention is not limited thereto, and other units smaller or larger than mm may be used according to the size of the cable.
As shown in fig. 8, the pattern 440 corresponding to the binary code may include a first sub-pattern 440-1, a second sub-pattern 440-2, and a third sub-pattern 440-3 in a lateral direction.
The first sub-pattern 440-1, the second sub-pattern 440-2, and the third sub-pattern 440-3 are formed of patterns corresponding to binary codes each containing the same data, and may be formed of the same pattern. That is, the first sub-pattern 440-1, the second sub-pattern 440-2, and the third sub-pattern 440-3 have the same shape and may include the same data. The pattern corresponding to the binary code is printed on the outer covering of the cable, and the printed pattern may be damaged or partially erased during circulation or construction of the cable. Since it may not be possible to identify in this case, a plurality of identical patterns are printed as shown in fig. 8 so as to be able to identify also in the case of a damaged pattern. At this time, the patterns 440-1, 440-2, 440-3 corresponding to the binary codes may be respectively formed such that the ratio of the width in the longitudinal direction D2 to the width in the transverse direction D1 is 1:2 to 1: 4.
Fig. 10 is a cross-sectional view of a cable of the cable management system illustrating one embodiment of the present invention.
Referring to fig. 10, a pattern corresponding to a binary code disposed on an outer cladding of a cable management system according to an embodiment of the present invention may be disposed in plural. When constructing the cable, a part of the cable may be buried in the ground or placed in contact with a facility such as a wall. At this time, when a portion on which the pattern corresponding to the binary code is printed is buried in the ground or is disposed in contact with a facility, the pattern corresponding to the binary code may not be recognized because it is not exposed. Therefore, in order to solve the problem that the pattern corresponding to the binary code is not exposed and thus cannot be recognized, a plurality of patterns corresponding to the binary code may be printed on the outer sheath of the cable. At this time, the central angles formed by the plurality of patterns corresponding to the binary codes may be the same in the sectional view.
For example, the central angles θ 1, θ 2 formed on the cross-sectional view of the first and second patterns 440a, 440b may be the same. In fig. 10, the central angles θ 1, θ 2 of the first and second patterns 440a, 440b formed in the cross-sectional view may be equal to each other by 180 degrees.
Fig. 11 is a cross-sectional view of a cable of the cable management system illustrating one embodiment of the present invention.
Referring to fig. 11, a pattern corresponding to a binary code disposed on an outer cladding of a cable management system according to an embodiment of the present invention may be disposed in plural. When constructing the cable, a part of the cable may be buried in the ground or may be disposed in contact with a facility such as a wall. At this time, when a portion on which the pattern corresponding to the binary code is printed is buried in the ground or is disposed in contact with a facility, the pattern corresponding to the binary code may not be recognized because it is not exposed. Therefore, in order to solve the problem that the pattern corresponding to the binary code is not exposed and thus cannot be recognized, a plurality of patterns corresponding to the binary code may be printed on the outer sheath of the cable. At this time, the central angles formed by the plurality of patterns corresponding to the binary codes may be the same in the sectional view.
For example, the central angles θ 1, θ 2, and θ 3 formed by the first, second, and third patterns 440a, 440b, and 440c in the cross-sectional view may be the same. In fig. 11, the central angles θ 1, θ 2, and θ 3 of the first, second, and third patterns 440a, 440b, and 440c formed in the cross-sectional view may be equal to 120 degrees.
Although the foregoing has been described with reference to embodiments, it will be understood by those skilled in the art that various modifications and changes may be made to the present invention without departing from the spirit and scope of the invention as set forth in the appended claims.
