Definitions

  • the invention relates to a device and a method for data transmission from a fixed base to a moving point (and vice versa), according to the features of the respective preamble of the independent claims.
  • slip rings So far, the data transmission via so-called slip rings.
  • a slip ring was mounted fixed and could be swept by a movable, in particular rotatable customer, with electrical contact between these two parts. Due to this electrical contact, the data or energy could be transmitted.
  • the invention is therefore based on the object to provide a method and apparatus for data transmission between a fixed and a movable part, with which the above-described disadvantages are avoided.
  • the data transmission is optically transmitted at the point where the fixed part and the movable part are in communication with each other.
  • the data is transmitted redundantly. This has the advantage that, in the event that a transmission channel between the fixed point and the moving point (and / or vice versa) should be disturbed, the data transmission is ensured via at least one further transmission link, or over exactly two transmission links.
  • energy is also transmitted with the transmission of the data.
  • This has the decisive advantage that, for example, no power supply has to be present at the moving point in order to supply energy there to existing sensors, actuators, control devices or the like.
  • This takes place via the data transmission according to the invention, so that a power supply can advantageously be dispensed with at the movable position.
  • a power supply to the is available, but such is not available in the area of the fixed Steep.
  • the method is used in work vehicles, in particular in cranes.
  • work vehicles such as cranes, construction machinery or the like are subject to a very heavy work load and thus a very heavy wear.
  • the replacement of the data transmission via slip rings or the like, as known from the prior art, in this case via an optical transmission has the very decisive advantage that not only the wear is reduced or completely eliminated, but that also the data transmission essential becomes more reliable. This can be done by the fact that the data is transmitted redundantly. Additionally or alternatively, corresponding transmission protocols can be used with which errors can be detected and even errors can be eliminated.
  • FIG. 1 there is a movable part 1, which is movable, in particular rotary, arranged to form a stationary part.
  • a data transmission which is schematically represented by the fact that the movable part 1 comprises a control device 3 and the fixed part comprises a control device 4.
  • These two control devices 3, 4 can be assigned individually or jointly to two actuators, sensors or the like. It is important that data between the moving part 1 and the fixed part 2 must be replaced.
  • the movable part 1 comprises means 5 and the fixed part 2 means 6, with which the data in the region of the point at which the two parts 1, 2 are arranged movable to each other, are transmitted optically.
  • These means 5, 6 are designed as a light emitter 7, or light receiver 8.
  • the means 5, 6 additionally have light receivers 9 and light emitters 0.
  • the means 5 only Lichtaussender or to provide in the means 6 only light receiver, with which then a unidirectional redundant data transmission is realized. This unidirectional data transmission then takes place only from one to the other part 1, 2, whereby further light emitters and light receivers can be provided so that a bidirectional data transmission can be realized redundantly.
  • Figure 2 shows an example of a light emitter 7 in the form of a light emitting diode 11.
  • other light emitters such as lasers or the like
  • the light receiver 8 which may be formed as a phototransistor 12.
  • Other embodiments of light receivers are of course also conceivable.
  • the light to be transmitted which is emitted for example by the LED 11, bundled or scattered in the direction of the light receiver 8 is sent.
  • the light emitted by the LED 11 can either be bundled or further scattered onto the phototransistor 12, for which purpose diaphragms, lenses or the like can be provided.
  • a particularly effective embodiment of the invention is to be seen in that the two parts 1, 2 are arranged close to each other in the region of their axis of rotation and in this area a diaphragm is arranged, which is used as a transmission medium for the emitted light in the direction of the light receiver.
  • a shutter has the advantage that it can be made to focus or diffuse the light passed through it.
  • the light beam guided between the two parts 1, 2 can be guided, widened or bundled.
  • such a diaphragm has the advantage that it prevents contamination because it optimally fills the space between the fixed and the movable part 1, 2 about the axis of rotation around.
  • a crane has an undercarriage (fixed part) on which a rotatable superstructure (movable part) is arranged. Between the undercarriage and the superstructure a data transmission (and possibly an energy transfer must take place). For example, located on the undercarriage, a control device whose control signals are to be delivered to actuators, which is located on the superstructure. The same applies to the superstructure, if it has sensors, the signals provided by the sensors to be delivered to the undercarriage and to its control device. In the point in which the superstructure is mounted movable, in particular rotatably mounted on the undercarriage, the optical data transmission takes place in accordance with the invention.
  • This optical data transmission has the advantage that it works wear-free and as a result no interference signals can interfere with the optical data transmission.
  • the signals are supplied to this point in electrical, in particular wired, form and also removed therefrom.
  • corresponding signal transducers are provided, which convert the supplied signals from electrical to optical, so that they can be transmitted by the optical transmission device. Once they have been transmitted, a conversion from optical into electrical takes place again so that it can be delivered to the following devices (such as control device, sensor, actuator, or the like).
