Definitions

  • the present invention relates to an arrangement and a method for detection and/or identification of components and in particular to an arrangement and a method for detection and/or identification of passive components detachably connected to an electronic device.
  • a radio-network basestation has many cables connected to it, including special, typically expensive cables like large antenna cables.
  • eNB evolved Node B
  • eNB evolved Node B
  • the knowledge about which components -including cables- are precisely installed at e.g. an eNB (evolved Node B) site supports self-configuration and optimisation of the system, and facilitates to manage a telecommunication system. For example, it would be very helpful for a technician to know in advance which "field replaceable units" pecisely are located at a certain eNB site before he drives into the field for maintenance or repair, so that he knows which spare parts to bring. In particular passive components, like cables, do not yet have such remotely readable identifiers.
  • Some of those basestation cables are very expensive, and for the maintenace aspects it would be useful to know exactly which concrete cable (including length, and additonal information like e.g. protection against animal damage) may need to be replaced.
  • This identification of cable connections also allows to check whether all cable connections are put together correctly during installation of the equipment. Possible human plugging-together-errors are detected immediately.
  • cable connections are subject to failure when they start getting loose - this startened loosening is usually not detected before the connection separates completely and thus could lead to a failure of the complete system. It would be nice to have a means to detect possible problems in time, so that it can be repaired -like fastening the connection- before the equipement fails.
  • a component to send an optical beam or some kind of electromagnetic beam including infrared light beam and UV light beam from e.g. a backplane of an equipment or device to the component.
  • the received optical or electromagnetic beam is coded with a signal and then sent or reflected back to the backplane of the device where the reflected optical or electromagnetic beam is received and where the information determined by the code is detected and can be further processed like e.g. transmitting a detected component identification information to a remote operation and maintenance (O&M) centre.
  • O&M remote operation and maintenance
  • first electromagnetic beam emitting means arranged at or in the device and adapted to emit and direct a first electromagnetic beam from the device to a component to be detected and/or identified; first electromagnetic beam receiving means arranged at or in the component and adapted to receive the first electromagnetic beam from the device; coding means arranged at or in the component and adapted for coding the received first electromagnetic beam with a code according to component's information; second electromagnetic beam emitting means arranged at or in the component and adapted to send a second electromagnetic beam coded according to the coding by the coding means from the component to the device; second electromagnetic beam receiving means arranged at or in the device and adapted to receive the coded second electromagnetic beam sent from the component, and processing means arranged at or in the device and /or a location remote from the device and adapted for processing the coded second electromagnetic beam for decoding the information from the code thereof.
  • the component is an electrically passive component like a cable plug or a plug connector not including active circuit elements, such as diodes or transistors. Otherwise, it may well be provided with active circuit elements and a supply voltage by means of supply voltage wiring within the cable plug or plug connector.
  • the electromagnetic beam may preferably comprise an optical beam including infrared and UV beams.
  • the second electromagnetic beam emitting means may be an optical beam reflector arranged in the passive component, e.g. a plug connector, said optical beam reflector being preferably arranged adjacent to a wall of the device in the plugged-in condition of the plug connector and in parallel or in a predefined angle to said wall.
  • the light reflector may in particular comprise one or a plurality of reflective surfaces arranged in the passive component.
  • the code of the coding means may be dedicated to the respective component or component's type at or in which the coding means are arranged.
  • the coding means may be adapted to change the code according to an actual condition of the component or of the component in its relation to the device.
  • an actual condition of the component may comprise at least one of the following conditions, namely an electrical condition, a mechanical condition (such as an incorrect locking of the cable connector at or in its socket), an environmental condition, a material condition and/or a condition based on a physical effect.
  • an electrical condition such as an incorrect locking of the cable connector at or in its socket
  • an environmental condition such as an incorrect locking of the cable connector at or in its socket
  • a material condition such as an incorrect locking of the cable connector at or in its socket
  • a material condition such as an incorrect locking of the cable connector at or in its socket
  • the present invention for solving the above object provides a method for detection and/or identification of components detachably connected to an electronic device, said method comprising the steps of: emitting a first electromagnetic beam from the device to a component to be detected and/or identified; receiving at or in the component the first electromagnetic beam from the device; coding at or in the component the received first electromagnetic beam with a code according to component's information; sending a second electromagnetic beam coded according to the coding by the coding means from the component to the device; receiving at or in the device the coded second electromagnetic beam sent from the component, and processing at or in the device and /or a location remote from the device the coded second electromagnetic beam for decoding the information from the code thereof.
  • a base station of a communication network an O&M center of a communication network and a communication network all of which comprise the inventive arrangement.
  • the present invention thus can be used for supporting the operation and maintenance (O&M) of telecommunications helping to make those complex systems more easily manageable with less costs and with less people's work.
  • O&M operation and maintenance
  • those persons skilled in the art and having studied the present specification are recognizing that obviously the present invention applies to many other technical fields beyond telecommunication systems.
  • the cable plug or plug connector needs no extra pins as it is the case in a coaxial connector.
  • the optical detection/ identification approach is also very robust with respect to electromagnetic interference problems especially in antenna cables of an RF transmitter where the close environment of the connector is disturbed by insufficient insulation or insufficient shielding against HF energy.
  • first electromagnetic beam emitting means arranged at or in the device and adapted to emit and direct a first electromagnetic beam from the device to a component to be detected and/or identified; first electromagnetic beam receiving means arranged at or in the component and adapted to receive the first electromagnetic beam from the device; coding means arranged at or in the component and adapted for coding the received first electromagnetic beam with a code according to component's information; second electromagnetic beam emitting means arranged at or in the component and adapted to send a second electromagnetic beam coded according to the coding by the coding means from the component to the device; second electromagnetic beam receiving means arranged at or in the device and adapted to receive the coded second electromagnetic beam sent from the component, and processing means arranged at or in the device and /or a location remote
  • the electromagnetic beam is implemented as an optical beam including visible light, infrared light or UV light
  • the first and second electromagnetic beam emitting means and the first and second electromagnetic beam receiving means are respectively implemented as first and second light emitting means and first and second light receiving means.
  • the component is represented by a cable plug which is connected to a socket on a backplane of an electronic device.
  • the exemplary cable plug may be implemented as an electrically passive component, not having electrically active circuit elements, such as supply voltage wiring, transistors and diodes, while the cable plug according to the fifth embodiment may also be implemented as an active component which is arranged to actively change the code of the coding means according to certain conditions of the component, i.e. the cable plug or according to its relation to the device.
  • first light emitting means in the example a plurality of light sources 21, 22 (for simplification, Fig.1 only shows first and second light sources 21, 22, e.g. a first and second laser diode) is located in an electronic device 1, e.g. behind a back plane of an eNB.
  • the first light emitting means 21 and 22 are configured to emit and direct a plurality of preferably parallel light beams (for simplification, Fig.1 shows only a couple of first light beams I 11 , I 12 ) towards a component, in the example a cable plug 10 to be detected and/or identified. It should be understood that there is also the possibility to use e.g.
  • First light receiving means in the example a light reflecting surface 11 is arranged in the optical path of the first light beams I 11 , I 12 and configured to receive and reflect the first light beams I 11 , I 12 at the site of the component 10.
  • the component 10 includes coding means 13 configured for coding the received first light beams I 11 , I 12 .
  • the coding means 13 may be implemented as a small transparent and/or reflective object which allows some coding of the light information.
  • this coding means 13 can be a small piece of glass or transparent plastic which is built at the side of the component 10. Depending on the concrete geometrical design, this piece of glass or transparent plastic can transmit the light or reflect the light according to the specific coding thereof.
  • the transmission or reflection can be inhibited by marking the surface of this glass or plastic piece. For example the marking could be achieved by making the surface rough in such a way that the glass or plastic piece is no longer reflective or transparent at a particular location. This marking may most easily be achieved by burning or scratching the former smooth surface of the transparent glass or plastic piece with a laser during production of the small transparent glass or plastic piece or during production of e.g. the cable plug 10.
  • the component 10 includes second light emitting means 12 , implemented as light reflecting means similar to the first light receiving means 11 and configured to send a plurality of second light beams (for simplification, Fig. 1 shows only a couple of second light beams I 21 and I 22 ) coded according to the coding of the coding means from the component 10 towards the device 1.
  • second light emitting means 12 implemented as light reflecting means similar to the first light receiving means 11 and configured to send a plurality of second light beams (for simplification, Fig. 1 shows only a couple of second light beams I 21 and I 22 ) coded according to the coding of the coding means from the component 10 towards the device 1.
  • a second light receiving means 3, e.g. a photo detector is arranged at or in the device 1 and configured to receive the coded second light beams I 21 and I 22 sent from the second light emitting means 12 at the component's 10 site.
  • a processing means 5 is arranged at or in the device 1 and/or at a location remote from the device 1 and configured for processing the coded second light beams I 21 , I 22 to determine information represented by the code.
  • the possibility of arranging the processing means 5 at a remote location is indicated by an interrupted line between the second light receiving means 3 and the processing means 5.
  • the coding exploits spatial and/or spectral diversity of the information:
  • the intended purpose of the coding method is to provide a simple and cheap way for coding, in case it would require much effort to increase e.g. the spatial resolution in one direction but still more coding information is needed, then it could be the simplest way to use a further dimension, like e.g. a second spatial direction, i.e. x+y-coding or a colored glass, or encoding by a hologram.
  • a further dimension like e.g. a second spatial direction, i.e. x+y-coding or a colored glass, or encoding by a hologram.
  • the coding means may be configured to change the code, and the processing means 5 in this case may be configured to detect or identify the change of the code and discriminate therefrom the condition of the component.
  • the second embodiment of the arrangement according to the invention depicted in Fig. 2 has many similarities with the first embodiment depicted in Fig. 1 .
  • the second embodiment differs from the first one described above in that the first light emitting means 2 only comprise a single light source and are configured to emit a single light beam I 1 towards the component 10.
  • the first light receiving means 11 and the second light emitting means 12 on the component's side are combined and implemented as a single reflecting plane.
  • the coding means 13, the second light receiving means 3 and the processing means 5 may be arranged and configured in a similar manner as it is done in the first embodiment according to Fig. 1 . Further the same principle different ways to achieve a coding as described above may be employed in the second embodiment according to Fig. 2 .
  • the third embodiment of the present arrangement depicted in Fig. 3 uses as the first light receiving means 11 a tilted transparent surface of a prism having a different dielectric constant as compared to the surrounding medium.
  • the first light beam I 1 emitted from the first light emitting means 2 contains several wavelengths and is widened into its spectrum at the tilted transparent surface 11. Different wavelengths are refracted with respectively different angles as simply indicated by the two refracted light beams I 11 and I 12 , the prism thus forming the coding means 13.
  • the refracted light beams I 11 and I 12 having different wavelengths are reflected at different locations of a reflective surface of the prism, serving as the second light emitting means 12, the different colored light forming e.g. a couple of second light beams I 21 , I 22 which are received by the second light receiving means 3 on the device's side and can be processed by the processing means 5.
  • the fourth embodiment of the present arrangement shows that the inventive arrangement can also be used for a plurality of components, e.g. several cable plugs 101, 102, 103 as plugged in on one plane of the device 1.
  • the second light receiving means 3 and the processing means 5 in common for all identification purposes together.
  • all cable plugs 101, 102, 103 are illuminated by different dedicated first light emitting means or light sources 21, 22 and 23 each configured for emitting a first light beam I 11 towards the cable plugs 101, 102, 103, possibly having different wavelengths.
  • These cable plugs have for example similar construction as the cable plugs in the embodiment depicted in Fig. 2 .
  • the different first light emitting means 21, 22 and 23 can be separately switched on and off.
  • Via light guides, e.g. optical fibers 41, 42, 43, the second light beams I 2 emitted from the different cable plugs 101, 102, 103 are guided towards a common second light receiving means 3, e.g. a light detector which is configured to distinguish the wavelengths of the second light beams I 2 .
  • the frequency information can be transmitted to the processing means 5 and there processed to get the component's identification.
  • the cable connector may comprise active circuit elements such as supply voltage wiring as well as transistors or diodes.
  • the component may comprise at least one sensor element, and the coding means may be configured to change the code according to a value sensed by the sensor element.
  • the processing means in this case may be configured to detect or identify the change of the code and discriminate thereof the condition of the component.
  • the sensing effect of the sensor element may be a pure physical effect, like a mechanical deformation of a bi-metal, an alteration of a direction of an optical axis for example by deflecting or scattering an optical beam at an optical element, etc.
  • Examples of possible modification of the code are provided as follows: When the connector plug 10 is loosening, then the distance between the device 1 and the component, i.e. the connector plug 10 and/or the angle of reflection is altered. This modifies the back-reflected light beam which can be detected by the device 1 and/or by the processing means 5. Further, overheating and thus thermal expansion can also alter the back-reflected light. Further, a wrong position of the connector plug 10, attached to the wrong socket or wrong device 1 is immediately detected.
  • the connector plug 10 may easily be provided with its own intelligence to modify the code according to the above conditions.
  • the fifth embodiment of the present arrangement as schematically depicted in Fig. 5 has some similarities with the third embodiment depicted in Fig. 3 , and those parts which are identical in both embodiments are designated by respectively equal reference signs.
  • the fifth embodiment includes an additional sensor means 14 that are configured to modify the code of the coding means 13.
  • Examples for an explicit sensor could be: a) a temperature sensor, e.g. a bi-metal which is configured to mechanically move a part of the light reflecting mirror surface 12; b) a moisture sensor configured to directly affect the reflective properties of the light reflecting mirror surface; c) a mechanical sensor configured to check if the connector plug is locked mechanically (e.g.
  • bajonet lock closed d) a means configured to read out if the connector plug has a blown fuse; e) an electromagnetic field sensing means configured for sensing if an electromagnetic field is present, e.g. by a crystal that modifies its optical properties in the presence of an electric or magnetic field (caused by voltage, current or power).
  • the latter method may also provide means for detecting what's going on inside the cable connected to the connector plug, i.e. to detect if a transmitter is injecting RF power in an antenna cable.
  • the advantage of providing an electromagnetic field sensing element in the connector plug is a cheaper way than adding an extra detection device somewhere else in the device or system and provides a kind of alive check of the cable.
  • the present invention also encompasses a method for detection and/or identification of components detachably connected to an electronic device, said method comprising the steps of: emitting a first electromagnetic beam from the device to a component to be detected and/or identified; receiving at or in the component the first electromagnetic beam from the device; coding at or in the component the received first electromagnet beam with a code according to component's information; sending a second electromagnetic beam coded according to the coding by the coding means from the component to the device; receiving at or in the device the coded second electromagnetic beam sent from the component, and processing at or in the device and /or a location remote from the device the coded second electromagnetic beam for decoding the information from the code thereof.
  • the present invention may be further embodied by a base station for a communication network, said base station comprising the arrangement for detection and/or identification of components as described above and further embodied by a communication network comprising the above described arrangement for detection and/or identification of components, and by an O&M center for a communication network comprising at least the processing means of the arrangement described above.
