Definitions
- the invention relates to a device for transmitting electrical signals or energy between a plurality of mutually movable units. 5
- the first of these transmission techniques uses a strip line for transmission, while the second of these transmission techniques uses a conductor structure consisting of a plurality of discrete dummy elements.
- This offers the advantage a very high interference suppression.
- Both conductor systems are not connected at the ends to form a closed ring like the conductor system cited first. They are open and can therefore be adapted to any trajectory.
- At both ends of these conductor structures there is a termination element for reflection-free termination.
- the signal is fed in at a suitable point in the conductor structure. This means that the signal is always transmitted from the conductor structure to a unit that is movably arranged relative to it.
- this system has serious disadvantages in various applications. Is z. If, for example, in the case of a linear transmission of the signals from movable crane systems to a stationary unit, a must be present on this movable crane system
- Antenna element which covers the entire length of the travel path, be attached. This means that a z. B. 50 m long antenna support must be attached. This is not feasible in practice.
- the conductor structure is applied to a mechanical slip ring that rotates with the rotating part. This enables data to be transferred from the rotating part to the stationary part without any problems, but transmission in the opposite direction requires an additional ring to accommodate a stationary conductor structure.
- the term conductor structure is used as a generic term for structures in which electromagnetic waves can propagate, such as arrangements of blind elements, strip lines or other conductor systems. Presentation of the invention
- the object of the invention is to present a device for the contactless transmission of electrical signals, which enables transmission from a movable unit to the conductor structure or the simultaneous transmission of signals in both directions.
- a symmetrical conductor structure operated with a differential signal is used, which is terminated at at least one end without reflection.
- This conductor structure can be any arrangement for conducting electromagnetic waves, such as arrangements of blind elements or strip lines.
- At least one of the two parts that are movable relative to one another has at least one directional coupler for signal coupling and decoupling.
- a particularly advantageous embodiment of the arrangement is designed such that signals can be transmitted in both directions.
- the signal is transmitted in the first direction by feeding the transmission signal into the conductor structure at a predetermined point.
- it makes sense to place the feed point in the middle of the conductor structure, that is, the location from both ends is equally far away. This means that the signal propagation times at both ends of the conductor structure are of the same length and, accordingly, the phase shift is zero. This leads to a continuous phase progression without jumps when the conductor ends are passed over.
- the signal transmission in the second direction takes place in the manner described above from the movable unit to the conductor structure.
- the receiver of the second direction can be attached to the same coupling point as the transmitter for the first direction on the conductor structure. In this embodiment, however, only half-duplex operation is possible. H. , Data can only be transmitted in one of the two directions at a time.
- a further advantageous embodiment of the invention consists in that the signals of the first and the second data transmission direction are separated from one another by means of directional couplers. This enables simultaneous transmission in both directions (full duplex operation).
- At least one of the two signals for the first or the second direction is additionally modulated on a carrier. If this carrier is selected outside the transmission range of the other signal, then a simple separation of the two signals is also possible in duplex mode.
- at least one directional coupler for decoupling the signals in a directionally selective manner is integrated in the carrier of the conductor structure.
- At least one directional coupler for the directional separation of the signals is integrated in the feed line to the coupling point of the conductor structure.
- both the coupling in and the coupling out of signals into the conductor structure takes place by means of units which are movable relative to the latter. This enables signal transmission between units moving at different relative speeds.
- an additional fixed coupling and decoupling of signals on the conductor structure is provided.
- At least one coupling unit which is movable with respect to the conductor structure is designed as a directional coupler. This means that signals can be coupled in or out depending on the direction. This allows a better separation of send and receive signals.
- a receiver is firmly connected to both ends of the conductor structure. Furthermore, there are at least two movable transmission units which are designed as directional couplers. These transmission units are arranged so that the first transmission unit Sends signals in the direction of the assigned first receiver. The second transmitter unit is arranged so that it transmits its signals in the opposite direction to the receiver assigned to it.
- a transmitter for the first signal transmission direction and a receiver for the second signal transmission direction are coupled to at least one end of the conductor structure by means of a directional coupler.
- this directional coupler can be constructed with line elements or also discrete components, such as transformers.
- a reception element designed as a directional coupler is provided for receiving the signals of the first transmission direction.
- the transmission or coupling of the transmission signals in the second transmission direction takes place via a second coupling unit that is movable relative to the conductor structure.
- the mobile receiver In order to avoid overcoupling of the signals from the mobile transmitter to the mobile receiver, the mobile receiver must be located on the side of the receiver which faces away from the transmitter assigned to the first signal transmission direction.
- At least one transmitter or receiver is permanently coupled to the conductor structure via directional couplers, and a movable transmitter which has a coupling element designed as a directional coupler is provided.
- the movable receiving unit can be designed here without any directional selection if it is located on the side of the movable transmitter which is remote from that end of the conductor structure. is facing, which is connected to the receiver of the second signal transmission direction.
- the movable coupling elements for the movable transmitter and the movable receiver are designed as directional couplers when the conductor structure is in permanent contact with the transmitter and receiver via directional couplers.

- the received signals are received here via a receiving element (6), which is firmly contacted to the conductor structure.
- FIG. 3 shows a particularly flexible embodiment of the invention.
- This coupling element can also be designed as a directional coupler. This enables communication between the two moving units.
- any number of the movable units can be provided.
- the arrangement shown here is basically functional without the two permanently installed units (6) and (16).
- Fig. 4 shows an example of an arrangement according to the invention with a receiving unit (17) permanently connected to the conductor structure, the input impedance of which together with the terminating impedance (3) ensuring a reflection-free termination of the conductor structure.
- NEN transmitter unit (18) whose output impedance ensures a reflection-free termination of the conductor structure. It is fundamentally advantageous to also terminate the conductor structure end used for stationary coupling without reflection. However, there are also applications where reflection at this end can be tolerated. In such cases, a low-ohmic feed-in is advantageous because of the higher signal amplitude that can be achieved with it.
- FIG. 6 shows an example of an arrangement according to the invention with a receiving unit (17) permanently connected to the conductor structure and a transmitting unit (18) permanently connected to the conductor structure.
- Fig. 7 shows an image for the simultaneous transmission of two channels.
- a receiving device is arranged at each end of the conductor structure.
- the signals from the movable units are coupled in via coupling elements, which act as directional couplers
- the coupling direction of both directional couplers (20), (21) points in opposite directions to the respectively assigned receivers. It is the transmitter for the first transmission direction with T1, the associated receiver with R1. The elements of the second transmission direction are marked with T2 and R2.
- the symmetrical conductor structures (1) are shown as simple lines in this and the following illustrations.
- the coupling elements for signal insertion or Coupling are designed as directional couplers, they are realized as symmetrical components.
- Directional couplers coupled to the conductor structure or coupling elements via lines these can be constructed either symmetrically or asymmetrically.
- An asymmetrical structure makes sense if the directional coupler is coupled to the symmetrical conductor structure via a balancing element such as a balun.
- Fig. 8 shows a similar arrangement with reversed data transmission direction.
- Transmitters (T1), (T2) are arranged at both ends of the conductor structure.
- the associated receivers (R1), (R2) are movably arranged via coupling elements which are designed as directional couplers (20), (21).
- the coupling direction of the two directional couplers is opposite, so that each receiver only receives the signals of the transmitter assigned to it.
- FIG. 9 shows an arrangement in which a transmitter (T1) and a receiver (R2) are coupled to one end of the conductor structure via directional couplers.
- the transmitter (T1) feeds the signal into the conductor structure for the first transmission direction, while the directional coupler (22) selectively routes the signal that comes from the conductor structure to the receiver (R2) of the second transmission direction.
- a directional coupler (20) is provided as a decoupling element for the first transmission direction, which selectively transmits the signals from the direction of the transmitter (T1) assigned to it to the receiver (R2).
- a transmitter (T2) is located on a second movable unit, which can be permanently connected to the first movable unit, and transmits its signals into the conductor structure by means of a directionally non-selective coupling element (27).
- the signal this transmitter now spreads in both directions in the conductor structure.
- it is fed to the receiver (R2) of the second signal direction via the directional coupler connected to the conductor structure, and on the other hand the second wave traveling in the opposite direction is absorbed by the reflection-free termination (3) of the conductor structure.
- FIG. 10 shows an arrangement in which the directionally selective elements are interchanged compared to the preceding arrangement.
- the transmitter (T2) of the second transmission direction is now coupled to the conductor structure via a directional coupler (20).
- the movable receiver is coupled to the conductor structure via a directionally non-selective coupling element (29). With this arrangement, directional selectivity in the movable receiver is not necessary, since the signal from the movable transmitter (T2) is transmitted exclusively in the direction of the receiver (R1) which is firmly connected to the conductor structure.
- FIG. 11 shows a further arrangement in which directional couplers are used for signal coupling in and coupling out of the movable units. This arrangement has the compared to the two previous arrangements
- the decoupling between the movable transmitter and the movable receiver is significantly higher.
- FIG. 12 shows an arrangement in which the transmitter (T1) for the first transmission direction and the receiver (R2) for the second transmission direction are firmly connected to the conductor structure by means of a directional coupler (22). Furthermore, a movable combi nated transmitter and receiver unit is provided, in which the signals from the transmitter (T2) and receiver (Rl) are also separated via directional couplers (23). For inclusion A directionally selective coupling element (29) is used to decouple the signals.
- the transmitter for the first signal transmission direction (T1) and the receiver (R2) for the second signal transmission direction are coupled by a directional coupler (26) approximately in the middle of the conductor structure.
- the coupling can take place at any point of the conductor structure.
- the signal phases of the signals at the ends should be as identical as possible. This can be achieved by the same signal transit time of both signals and thus by the same conductor lengths.
- the unit that is movable relative to this conductor structure is designed such that it can send or receive data from any position of the conductor structure.
- the data (T2) are sent from the movable unit using the directionally non-selective coupling element (27).
- the signals (R1) are received either via one of the two directional couplers (24) or (25).
- the signal (T1) is coupled into the conductor structure and is coupled out via the directional coupler (25) to the receiver (R1).
- the directional coupler (24) can only couple out a negligible signal portion because of the wrong direction.
- Linking the two Directional coupler takes place in the linking unit (28) either via an adder or also via a changeover switch, which can be controlled, for example, by a position encoder.
- FIG. 14 shows an improved embodiment of the arrangement shown in FIG. 13. If the coupling element (27) is located directly above the stationary coupling point of the transmission signal (Tl) or of the reception signal (R2) in the arrangement from FIG. 13, reception is not possible since the transmission signal extends in the directions of the conductor structure greatest coupling loss along the directional couplers (24) and (25) moves. This means that only a very small signal component can be coupled out. This is remedied by the arrangement shown in FIG. 14.
- the conductor structure is divided into two pieces. As before, both pieces have the entire conductor structure terminated at both ends by the terminating impedances (2), (12) and (3), (13) without reflection.
- the stationary feed points are located close to each other at a distance which is, however, at least as large as one of the two directional couplers (24) or (25) used for moving signal coupling plus the length of the coupling element (27). This ensures that at least one of the two directional couplers (24) or (25) receives a signal in the direction (T1) in the signal direction of low attenuation.
- the two signals decoupled by the directional couplers (31) and (32) are linked to one another via a unit (33).
- This unit (33) can be designed as an adder or can also contain a switch which switches depending on the position or signal strength between the two signals from the directional coupler (31) or (32).
- 15 shows a particularly simple embodiment of the invention. For the sake of clarity, only the coupling device of one of the movable elements is shown.
- the signals are coupled in and out via two mutually independent, spatially separated coupling elements.
- the signal of the second transmission device (T2) is coupled out into the conductor structure via the first of these two coupling elements (35).
- the received signal is coupled out via the second coupling element (36) and passed on to the evaluation unit (34).
- This evaluation unit has the task of separating the received signal, which contains a sum of the signals of the transmitter (Tl) of the first transmission device and of the transmitter (T2) of the second transmission device, according to transmission directions. In the simplest case, this is done by subtracting a certain proportion of the transmission signal (T2), which roughly corresponds to the signal attenuation between the two coupling elements and the conductor structure.
- the difference is the received signal for the first direction (Rl).
