Description

  The present invention relates to a cable, a cable manufacturing method, and a cable position specifying method.

2. Description of the Related Art Up to now, manufacturing data obtained when manufacturing a cable has been recorded in the form of a manufacturing letter or stored separately from the cable in a computer. Such manufacturing data includes, for example, cable type, number of individual fibers, type of individual fibers, unique characteristic data for cables or individual fibers, and the like.

  In particular, continuous metric values (meter length) are usually printed or stamped on the exterior of the cable using an ink printer or a strip or foil made of paper / plastic when manufacturing the cable. The length of the intervening cable section is determined by two metric values. However, once the cable is laid, information about the metric value can no longer be obtained.

  In addition, cables embedded in the ground can have corrugated points, so the length of the cable section embedded between the two locations and the distance between the two locations required on the design drawing, for example. Then, it is no longer possible to make an exact correspondence.

  German Offenlegungsschrift DE 19 14 540 proposes a cable and a measuring device for cable length detection, in which the cable carries a data carrier such as a transponder, bar code or magnetic stripe in a predetermined longitudinal position. They can be read by a data reading device. The advantage in the case of transponders or magnetic stripes is that the contents of their data carriers can be changed by a writing device. Thereby, it is possible to accept information other than the length information.

  When applying a transponder device to a cable, the following must be considered. That is, the transponder device must be protected from external influences on the cable, such as mechanical loads and shocks, or moisture ingress. Furthermore, this transponder device must be arranged as follows. That is, they must be arranged so that they are not directly exposed to the high temperatures that occur during cable production, for example during the extrusion process.

Problem to be Solved by the Invention An object of the present invention is to provide the following cable. In other words, the transponder device is installed in the cable to provide a wide range of accurate information about the cable on the manufacturing side, to facilitate access to that information, and to protect as much as possible from the effects of cable manufacturing and cable laying. It is to provide an integrated cable. A further object of the present invention is to provide the manufacturer with extensive and accurate information about the cable, to facilitate access to that information, and to protect as much as possible from effects during cable manufacture and cable use. It is to provide a method for manufacturing a cable in which a transponder device is integrated in the cable. It is a further object of the present invention to provide a method for specifying the location of such cable laying locations.

Means for Solving the Problem The problem is solved by the cable described in the characterizing part of claim 1, solved by the cable manufacturing method described in the characterizing part of claim 16, and described in the characterizing part of claim 21. This is solved by an improved cable location method.

BEST MODE FOR CARRYING OUT THE INVENTION This cable includes a transponder device, a cable sheath, a transmission element, and a blade. The transponder device stores a memory for storing digital data and the digital data. A transponder for wireless transmission, wherein the cable sheath surrounds the transponder device, the transmission element is surrounded by a cable sheath, and the transponder device is disposed between the transmission element and the cable sheath. The blade surrounds the transmission element and the transponder device so that the transponder device is held on the transmission element by the blade, and the blade sufficiently protects the transponder device from thermal influences. It is configured.

  Such a transponder device is usually also referred to as an RFID tag (Radio Frequency Identification Tag), a smart chip or a green tag. The transponder device receives, for example, a radio pulse from a communication device, particularly a reading device or a writing device, via an antenna, and returns fixed or variable information. The transponder device is integrated into the structural structure or core of the cable during manufacture and includes the functions necessary for the storage and exchange of digital data within the label. The cable or line includes electrical or optical conductor paths, which are provided for energy transfer or message transfer. A passive transponder device (which obtains the power necessary to operate the device from the signal of the communication device) has a virtually infinite lifetime and is insensitive to dust, oil and static electricity. A typical storage capacity of such a transponder device is 2 MB (Mega Byte). The digital data can include, for example, manufacturing information and information depending on the length of the cable section. These data are read from or written to the memory at a high transmission rate without a visual link in the wireless path. Data exchange occurs regardless of location. That is, it is performed without placing the communication device and the transponder device at a predetermined relative position. However, the transponder device may be detected and located by a suitably configured communication device if transponder device positioning is required for cable or label route detection.

  Storage of information on the cable on the manufacturing side can be difficult if the data is stored separately from the cable when the information about the cable from the manufacturer is associated with the cable. To avoid.

  After the cable is manufactured, the cable sheath provides the transponder device with more protection than the support element. The insertion of the transponder device into the cable core surrounded by the cable sheath ensures the protection of the transponder device against the temperature generated in the sheath extruder.

  The fixation of the transponder device to the transmission element allows a simple installation of the transponder device in the sheath extruder.

  The blade separates the transponder device from the cable, thereby effectively protecting against the temperature generated by the sheath extruder.

  The cable preferably comprises a longitudinal strip-like support element, to which the transponder device is fixed.

  The support element may be a plastic band or may have a circular cross section. The transponder device may be cast into this support element. In this way, the transponder device is already protected from dust, oil and static electricity during cable production.

  The blade includes a fibrous holding element.

  This fibrous holding element may be extruded from the melt.

  The fibrous holding element preferably contains carbon fibers (Kevlar fibers) or glass fibers.

  This Kevlar fiber or glass fiber can also be effective against tensile loads.

  The transmission element preferably comprises an optical waveguide, and the cable is preferably composed solely of a dielectric material in the peripheral region surrounding the transponder device.

  If no metal is disposed in the vicinity of the antenna of the transponder device, the digital data stored in the transponder device can be read out over a relatively long distance by the communication device.

  The transmission element preferably includes a metallization.

  With the appropriate orientation of the antenna of the transponder device, the impact of the metal conductor path can be partially compensated.

  The cable preferably includes a cable sheath in which the transponder device is embedded. The cable sheath preferably in this case comprises two layers, which are produced by an extrusion process. The transponder device is deposited on the first metal layer. A second metal layer is subsequently extruded onto it.

  The transponder device can be exposed to a temperature of about 200 ° C. A temperature of about 85 ° C. is generated during sheath extrusion. This transponder device can be pushed into a hotter cable sheath, for example.

  The cable preferably includes a transmission element, which has a sleeve. In this case, the transponder device is surrounded by this sleeve.

  That is, the transponder device may be arranged inside the transmission element. In this case, it is conceivable that the cable comprises a plurality of such transmission elements, each having one corresponding transponder device. The internal structure of the cable is reflected by the information read together from the cable.

  The transponder device includes a processor, and the processor is supplied with power and a system clock via the transponder, and the processor reads digital data from the memory and transmits the digital data via the transponder. Is configured to implement.

  Digital data received via the transponder can be written to memory by the processor.

  The memory of the transponder device can be written for the first time, for example, during the manufacturing process or after manufacturing. Furthermore, the digital data contained in the memory can be updated after cable repair.

  The longitudinal section of the cable has a predetermined length, and the digital data in the memory includes information regarding the length of the longitudinal section.

  The cable metric is read by the communication device over the wireless path. By reading out the number of meters at two different locations, the length of the cable section installed between these locations can be detected.

  The digital information in the memory includes a first feature, and a second feature is defined by additional digital data received by the transponder, the digital data in the memory comprising the first feature and the second feature It can be read from the memory only if the features match.

  The first feature may be a security feature stored in the transponder device at approximately the manufacturer. The keyword transmitted from the communication device is inspected based on the security feature (information), and the stored data may or may not be transferred depending on the inspection result. The digital data so stored is protected from unauthorized access.

  The first feature advantageously includes information regarding the length of the longitudinal section of the cable.

  This first feature may include the number of meters stored in the transponder device. The second feature may include a test value. This transponder device may be configured as follows. In other words, it may be configured to respond to the transmission signal only when the test value matches the stored number of meters. By doing so, it is possible to realize a collision-free protocol in which only one of the plurality of transponder devices arranged within the response range of the communication device responds.

  The transponder device is preferably configured as a passive system. In this case, it is not necessary to provide an energy supply device on the chip containing the transponder device. The energy for operating the transponder device is picked up directly from the electromagnetic field of the communication device, for example.

  According to another embodiment of the invention, the transponder device is configured as an active system including a unique supply device for providing an energy supply for the transponder device. In this case, the energy for supplying the transponder device is preferably provided by a rechargeable supply device. According to a further feature of the present invention, the rechargeable supply device is configured as a rechargeable storage battery. This rechargeable supply device is advantageously rechargeable over a wireless path.

  The transponder device thereby does not require exposed connectors or the like for supplying power or exchanging digital data, and can be inserted into the cable in shield form without any wear or maintenance. A transponder device with a rechargeable storage battery can be used when a transponder with a wide effective range is desired or when the cable contains a transmission element with a metallization.

  The use of a rechargeable storage battery ensures that the user can use the functions of the transponder device indefinitely in time. When the storage battery is discharged, or when the storage battery has reached a discharged state due to access to the transponder that has already been performed many times, it is no longer possible to write or read information from the memory of the transponder device, The supply device providing the energy supply for the transponder device is charged again. This charging is advantageously done wirelessly via a radio link, so there is no need to dig a cable embedded in the ground. Nevertheless, if a battery is used for energy supply, it is better to have the battery respond only to transmissions to ensure long life.

  A method for manufacturing a cable according to the invention comprises the steps of providing a transmission element comprising at least one optical waveguide and providing a plurality of transponder devices each having a memory for storing digital data. Contains. The transmission element and the plurality of transponder devices are supplied to a manufacturing unit. In this production unit, a blade is generated which holds the transponder device on a transmission element. A cable sheath is pushed around the blade. In this case, the transponder device is sufficiently protected by the blade from the high temperatures that are generated when the cable sheath is pushed out.

  In manufacturing the cable, for example, a plurality of transponder devices are supplied to the sheath extruder at regular intervals. In this sheath extruder, the cable sheath is extruded around a plurality of transponder devices, and the temperature in the sheath material at that time reaches about 85 ° C. Since normal transponder devices can be exposed to temperatures up to 200 ° C., these multiple transponder devices can be inserted into the hotter sheath material.

  Typical blades include, for example, strain relief elements and expanding felt. Many ordinary substances are also suitable for improving the heat resistance of the transponder device against the temperature generated in the sheath material immediately after the sheath is extruded.

  The step of producing the blade advantageously includes the step of supplying Kevlar fiber or glass fiber.

  This Kevlar fiber or glass fiber is usually used for relaxation of tension and strain.

  The method advantageously includes providing a writing device for wirelessly transmitting digital data to each one of the plurality of transponder devices, and writing the digital data into a memory of each of the plurality of transponder devices. Is included.

  The transponder device can be programmed before or after insertion into the cable. After insertion into the cable, each of the plurality of transponder devices can only be programmed via the transponder. Therefore, the memory must be writable by the processor. It would also be possible to program the memory bypassing the transponder and processor before insertion into the cable and especially before sealing the transponder device. Thus, the memory may be implemented such that it can only be read by the processor.

  The method advantageously includes the step of supplying a plurality of transponder devices to the production unit with a longitudinal section of strip-shaped support element, the support element being divided into a plurality of sections in the longitudinal direction, Each one of a plurality of transponder devices is fixed to the surface of the section.

  The support element may have a circular cross section, for example, or may be embedded in the cable with a supply device provided for the transmission element or the tension relief element.

  Said method advantageously includes the step of twisting the support element together with the transmission element.

  Such twisting is advantageous, for example, when the mechanical properties of these support elements and transmission elements are similar to each other. However, it is also possible for a plurality of transmission elements to be twisted around the support element.

  A method for locating a predetermined portion of a cable includes the steps of supplying a cable according to the present invention, storing digital data in a memory of a transponder device that can determine the length of a longitudinal section of the cable, and A first measurement signal propagating along the cable and via the cable on the premise that a second measurement signal is generated by reflection of the first measurement signal at a predetermined location existing along the cable. Providing a measuring device for detecting an incoming second measurement signal and detecting a delay time between the first measurement signal and the second measurement signal. From the delay time, an interval distance between the measuring device and a predetermined location is determined. The method further includes providing a reader having a spatially limited response range depending on the position of the reader, wherein digital data if the transponder device is within the response range. Can be read from the transponder device by the reading device. The method further includes reading the digital data from the memory, determining the length of the longitudinal section of the cable, and associating the length with the position of the reader. The position of the predetermined location is obtained by comparing the interval obtained from the delay time with the length read from the memory of the transponder device.

  The length of the cable section installed between the two locations can be detected by reading the digital data. The distance between the two locations can be estimated from the position of the reading device and the size of the response range. Thereby, for example, the position coordinates can be estimated relatively accurately from the meter mark on the cable buried in the ground.

  By measuring the propagation time or delay time of the electromagnetic signal reflected from the line interruption point, the cable length from the measurement position to the line interruption point can be obtained. Accordingly, the progress of the cable can be tracked, and length-dependent information can be read from each of the plurality of transponder devices. When a point corresponding to the length obtained from the delay time measurement is reached, the adjacent transponder device can be located with maximum accuracy by narrowing down the response range, and the position of the line interruption or breakage point can be interpolated appropriately. Determined by. Finally, the corresponding cable is dug to remove the portion where the line is broken.

  The method further advantageously includes the step of reducing the response range for a more precise narrowing down of predetermined points of the transponder device.

  For example, one response range initially has a radius of about 30 m, and this radius is then stepped down to, for example, about 1 m in order to accurately locate one of the transponder devices. Also good.

  FIG. 3 shows a cross-sectional view of a cable according to the invention. The cable 40 includes a cable sheath 41 and generally a plurality of transmission elements 400, which are surrounded by the cable sheath 41. Each transmission element 400 includes a sleeve 401 and generally includes a plurality of conductor tracks 4000, eg, a plurality of optical waveguides and / or electrical conductor tracks.

The cable 40 may include a blade 43 that surrounds the transmission element 400. The blade may include a fibrous holding element 431, such as carbon fiber (Kevlar fiber) or glass fiber. This fibrous holding element may be used for tension or strain relaxation. The cable includes a plurality of transponder devices 10, which are secured to a support element 60 that extends in the longitudinal direction of the cable 40. This support element 601 is preferably a film made of plastic, to which the transponder device 10 is fixed. The support element 60 and the transponder device 10 are disposed between the transmission element 400 and the fibrous holding element 431, for example. The support element 60 and the transponder device 10 may be disposed between the blade 43 and the cable sheath 41. The transponder device 10 may be further individually embedded in the cable sheath 41.

  FIG. 4 shows an embodiment of a cable manufacturing method according to the present invention. The manufacturing section for manufacturing the cable 40 includes a plurality of sleeve extruders 81, a twisting and knitting device 82, a sheath extruder 83, and a cooling section 84. In each of the sleeve extruders 81, a corresponding sleeve 401 is typically extruded around a plurality of corresponding conductor tracks 4000, eg, optical or electrical conductor tracks, thereby producing each of the transmission elements 400. On the other hand, the sleeve extruder 81 is supplied with a corresponding waveguide 4000 and a melt of the sleeve material 811 each time. In the twisting and knitting device 82, the transmission elements 400 are first twisted together and subsequently the blade 43 is assembled to form the cable core 42. On the other hand, the twisting and knitting device 82 is supplied with a transmission element 400 and a fibrous holding element 431. The fibrous holding element 431 may be extruded from a melt of blade material. In the sheath extruder 83, the cable sheath 41 is pushed out around the cable core 42, whereby the cable 40 is formed. In contrast, the sheath extruder 83 is supplied with a melt of the cable core 42 and the fluid sheath material 831. The cable 40 is cooled along the cooling section 84 and wound on a cable drum.

  The production section further includes a supply unit 85 for providing the transponder device 10 in the cable. The transponder device 10 is attached to a belt-like support element 60 extending in the longitudinal direction by, for example, an assembling device 85 and is inserted into the cable sheath 41. This support element 60 is supplied to the twisting and knitting device 82 together with the transmission element 400, for example. Thereby, it is achieved that the blade 43 surrounds the support element 60 and the transponder device 10.

  The support element 60 can also be supplied to the sheath extruder 83 along with the cable core 42. Thereby, it is achieved that the transponder device 10 is arranged between the cable core 42 and the cable sheath 41.

  The manufacturing section may further include a writing device 2012 for programming the transponder device 10. The transponder device 10 can be programmed before or after insertion into the cable 40. At this time, each memory 123 of the transponder device 10 stores digital data 1231 and, in particular, information regarding the length d of the section of the cable 40 disposed between each transponder device 10 and the reference position 70. The

FIG. 5 shows an embodiment of a method for measuring the position of the cable 40 and specifying the position of the line defect location. A plurality of transponder devices 10 are provided in the cable 40. Between each of these transponder devices 10 and the measuring position 70, one longitudinal section of the cable 40 is arranged, which longitudinal section has a corresponding length d. Between the first and second transponder devices 10 and the reference position 70, the respective longitudinal sections of the cable 40 having lengths d ₁ and d ₂ are arranged. Each of the first and second transponder devices 10 stores respective lengths d ₁ and d ₂ . A line defect 71 exists between the first and second transponder devices 10. At the reference position 70, the cable is accessible. In order to locate the line defect 71, a signal propagating along the cable 40 is first generated at a reference position 70 using a measuring device 90 connected to one of the conductor tracks 4000. A part of this signal is reflected by the line defect 71 and detected by the measuring device 90. From the delay (propagation) time Δt of a part of the reflected signal, the length Δs of the section of the cable 40 arranged between the reference position 70 and the line defect is determined. Thereby, the first and second transponder devices 10 having a line defect between them are located. In response, the reader 20 moves along the approximate route of the cable 40 from the reference position 70 toward the line defect 71. Meanwhile, a first signal 51 is transmitted from the reader 20. Each transponder device 10 present in the response range 2011 around the reading device 20 receives power and system clock via a first signal 51 and is stored in the transponder device via a second signal 52. Data 1231 is transferred. In this way, the digital data 1231 of each transponder device 10 installed in each response range 2011 is read by the reading device 20. When no data is read, there is no transponder device 10 in the response range 2011. When at least one transponder device 10 exists in the response range 2011, the length d of the longitudinal section of the cable 40 arranged between the at least one transponder device 10 and the reference position 70 can be detected. At the same time, the response range 2012 and position 2010 of the reader 20 are known. In particular, if the digital data 1231 from the first and second transponder devices 10 is read by the reading device 20 with the stored values for the lengths d ₁ and d ₂ respectively, the first and second A line defect 71 located between the transponder devices 10 is present in the response range of the reading device 20, and the position is measured or specified accordingly. The accuracy of the position measurement method described above can be improved by the following. That is, it is possible to improve the response range 2011 by limiting the radius and / or solid angle by reducing the transmission output and / or using a directional antenna.

  FIG. 6 shows a block circuit diagram of the transponder device 10 of the cable 40 according to the present invention. The circuit includes a transmitter 124 and a receiver 125 (which are each connected to the antenna 11), a processor 122 connected to the transmitter 124 and the receiver 125, and a memory 123 connected to the processor 122. Is included. The circuit further includes a rectifier 120 connected to the antenna 11 and a clock controller 121 connected to the antenna 11, and the rectifier 120 supplies a DC voltage to the processor 122, the transmitter 124, and the receiver 125, and The clock control unit 121 supplies the system clock C to the processor 122. A rechargeable storage battery 126 is provided to supply voltage C to the rectifier 120. This storage battery 126 is then advantageously rechargeable by radio means (eg wireless). Thereby, the transponder device can be used any time after a short charging period. Searching or digging up the cable and transponder device is avoided by charging the storage battery via this wireless link. Instead, the battery is charged by users on the ground.

  It is also possible to use a pure passive system. In that case, the storage battery 126 is not provided in FIG. For passive energy supply of the transponder device 10, electric power is picked up from the electric field radiated from the reading device to the antenna 11 and used for the operation of the transponder device.

  The digital input data I is read from the first signal 51 received via the antenna 11 by the receiver 125 and transferred to the processor 122. The digital output data O transferred from the processor 122 is inserted into the second signal 52 by the transmitter 124. The input data I is used for control by the processor 122 or stored in the memory 123. Output data O is read from the memory 123 by the processor 122.

  FIG. 7 shows the electromagnetic coupling between the circuit example of the transponder device 10 according to the invention and the reading device 20. The antenna 11 of the transponder device 10 and the further antenna 21 of the reading device 20 are each configured as an inductively coupled coil. The inductance and input capacitance 1251 of the antenna 11 form a parallel resonance circuit that is attenuated by the winding resistance 111 and the load resistance 1252 of the antenna 11, and the resonance frequency is adjusted to the transmission frequency of the reading device 20.

  In order to read out the digital data 1231 stored in the transponder device 10, a high-frequency alternating magnetic field is generated in the further antenna 21 of the reading device 20. As a result, a high-frequency AC voltage is induced in the antenna 11 of the transponder device 10. From this high-frequency AC voltage, a DC voltage and clock frequency for power supply and clock control of the processor 122 are derived.

  The switch S is controlled by the output data O transferred from the processor 122 of the transponder device 10 to the transmitter 124. For example, the high level corresponds to the connected state of the switch S, and the low level corresponds to the opened state of the switch S. When the switch S is closed, a further load resistor 1253 is connected in parallel to the load resistor 1252. That is, the total load resistance of the parallel resonant circuit changes depending on the state of the switch S. A relatively high current flows through the antenna 11 under a small load resistance. The change in the total load resistance affects the change in the current flowing through the antenna 11 and causes an additional voltage at the further antenna 21 of the reader 20 as a result of inductive coupling. The output data O is transferred from the transponder device 10 to the reading device 20 by this so-called transformer coupling.
