Definitions

  • the invention relates to an arrangement for signal transmission between galvanically separated circuits with a arranged in a circuit transmitting device with a single transmission module, which is set up for the delivery of a signal and one of the transmitting device galvanically separate receiving device, which is adapted to receive the signal.
  • Such an arrangement is known for example as so-called optocoupler from the German patent application DE 102 28 390 Al.
  • the known arrangement has a transmitting device in the form of an emitting photodiode and a receiving device in the form of a receiving photodiode. Between the two photodiodes, an optical waveguide for specifying the signal path, ie the light path, from the emitting photodiode to the receiving photodiode is provided.
  • it is possible to transmit a signal from a first circuit to exactly one galvanically separated from this second circuit. If a signal is to be transmitted to a plurality of galvanically separated circuits, then correspondingly many of the known optocouplers are required, which must be connected in parallel on the transmitting side.
  • the invention has for its object to provide a generic arrangement with which comparatively little effort and cost signal transmission to a plurality of galvanically separate circuits is possible.
  • the receiving device contains at least two individual receiver modules, which are arranged in circuits which are galvanically separated from one another and are each set up to receive the signal emitted by the transmitter module.
  • the invention strug is based on the finding that it is perfectly sufficient to assign a transmitting device with only one transmission module of a receiving device having a plurality of receiving modules for transmitting a signal to a plurality of electrically isolated circuits. In this case, the signal output by the transmitting module is detected by all the receiving modules and relayed to their respective circuits. The number of required receiving modules results from the number of existing galvanically isolated circuits that are to receive the output signal from the single transmitting module.
  • the transmitting device and the receiving device are set up for the transmission of optical signals. Due to their high propagation speed of the light, optical signals are particularly well suited for the almost simultaneous control of several receiving modules by a single transmitting module.
  • Free in this context means that there is a rectilinear signal transmission path between the transmission module and the reception module, for example in the medium air, along which the signal is transmitted without a forced change of direction.
  • An advantageous embodiment provides in this context that the individual receiving modules of the reception direction are arranged opposite the transmitter module on a line.
  • a possible other embodiment is given by the fact that the individual receiving modules of the receiving device are arranged opposite the transmitting module on at least two parallel lines.
  • the receiving modules of the receiving device are arranged on a curve extending around the transmitting module.
  • An advantageous embodiment of this latter alternative also provides that the receiving modules are arranged on a circular path extending around the transmitting module.
  • At least one reflection surface is arranged in the signal path between the transmission module and the individual reception modules.
  • the signal emitted by the transmission module can be forced by the reflection surface to change direction and thus be deflected in the direction of the individual receiving modules. In this case, there is thus no uninterrupted signal path between the transmitting module and the receiving modules.
  • An advantageous embodiment provides in this context that the transmission module and the receiving modules are arranged along a line.
  • a further advantageous embodiment finally provides that the signal path runs along a signal conductor, in particular an optical waveguide.
  • the signal in particular a light beam, can be guided particularly flexibly between the transmitting and each receiving module.
