APPARATUS FOR THE BIDIRECTIONAL TRANSFER OF INFORMATION
用于信息双向传输的装置

TECHNICAL FIELD OF THE INVENTION
发明的技术领域

The invention relates to apparatus for the bidirectional transfer of information in systems having at least one rotating unit, for example from a rotor to a stator.
本发明涉及在具有至少一个旋转单元的系统中双向传输信息的装置，例如从转子到定子。

BACKGROUND OF THE INVENTION AND PRIOR ART
发明背景和现有技术

For the transfer of information, for example from and to shafts, mechanical processes such as slip-ring processes, mercury bath processes and telemetry processes are known.
对于信息传输，例如从轴传输和传输到轴，机械过程（例如滑环过程、汞浴过程和遥测过程）是已知的。
In such processes the problem arises that the quality and quantity of transfer are limited. Particularly in the case of mechanical systems, wear and inaccuracy of transfer on account of potential fluctuations give rise to problems. While these problems are not so great when mercury cells are used, these have their own disadvantage of a high outlay on maintenance owing to changes in the mercury bath with time due to contamination and amalgam formation.
在这样的过程中，出现了一个问题，即转移的质量和数量是有限的。特别是在机械系统的情况下，由于潜在波动而导致的磨损和传输不准确会引起问题。虽然使用汞池时这些问题并不那么严重，但也有其自身的缺点，即由于污染和汞合金形成，汞浴会随着时间的推移而变化，因此维护费用高。
A particular problem that arises in the case of known transfer systems is the connection, typical of the system, of the energy supply to the frame potential and the supply voltage, since the transfer can be impaired by naturally occurring potential fluctuations. In addition, interference can be further amplified by the usual analog signal transfer. This can lead to falsification of the information in the course of transfer. The high wear leads to all mechanical systems having high maintenance costs.
在已知传输系统的情况下出现的一个特殊问题是系统的典型能量源与框架电位和电源电压的连接，因为自然发生的电位波动可能会损害传输。此外，通常的模拟信号传输会进一步放大干扰。这可能导致在传输过程中信息被伪造。高磨损导致所有机械系统的维护成本很高。
In contrast to this, German Offenlegungsschrift 4034578 describes a rotary transmitter which avoids the disadvantages of the mechanical and mercury cell transfer systems. This comprises a stator and a rotor. The stator has an interface for a digital control signal, an interface for transfer of energy to the rotor and an interface for the incoming signal from the rotor, while the rotor includes modules for processing the measurement signals, for processing the control signals and for supply voltage conditioning. The energy for the rotor modules is transmitted by means of a pot-type core transformer the primary winding of which is located in the stator, and is consequently stationary, while the secondary winding is in the rotor, the two windings being so arranged that an inductive energy supply is obtained for the rotor and its modules.
与此相反，德国 Offenlegungsschrift 4034578 描述了一种旋转发射器，它避免了机械和汞池传输系统的缺点。这包括定子和转子。定子有一个数字控制信号接口、一个用于将能量传输到转子的接口和一个用于从转子输入信号的接口，而转子包括用于处理测量信号、处理控制信号和电源电压调节的模块。转子模块的能量通过罐式铁芯变压器传输，其初级绕组位于定子中，因此是固定的，而次级绕组位于转子中，两个绕组的布置为转子及其模块获得感应能源供应。
For the optical transfer of the information output from the rotor a transmitter diode is located on the axis of rotation of the rotor at the interface to the stator and a receiver diode facing the transmitter diode is located in the stator on the prolongation of this axis. Because of the course of the transfer path on the axis of rotation the signals output from the rotor diode can be transmitted without interference and continuously. However, for the control of its modules the rotor requires a control signal, which must be transmitted from the stator to the rotor. Since a transfer on the axis of rotation, which is already occupied, is excluded, a high constructional outlay is necessary to provide another transfer path.
对于转子输出的信息的光传输，发射二极管位于转子旋转轴上，在与定子的界面处，面向发射二极管的接收二极管位于定子中，位于该轴的延长线上。由于旋转轴上的传输路径的路线，从转子二极管输出的信号可以不受干扰地连续传输。然而，为了控制其模块，转子需要一个控制信号，该信号必须从定子传输到转子。由于排除了已经被占用的旋转轴上的传输，因此需要高昂的结构支出来提供另一条传输路径。
For the transfer of the control information from the stator to the rotor the Offenlegungsschrift proposes a central receiver diode, fixed to the rotor, with a ring of transmitter diodes on the stator side and distributed equidistantly around it.
为了将控制信息从定子传输到转子，Offenlegungsschrift 提出了一个固定在转子上的中央接收器二极管，在定子侧有一圈发射二极管，并在其周围等距分布。
The twelve transmitter diodes required to cover the light signals for one revolution are located in the stator ring
覆盖一圈光信号所需的 12 个发射器二极管位于定子环中
surrounding the receiver diode on the rotor side. The transfer of information between rotor and stator by means of thirteen diodes (twelve transmitters and one receiver) involves a high constructional outlay. The transfer path which lies on the axis of rotation and makes possible a simple direct transfer using one transmitter and one receiver is already occupied by the transmitter of the rotor and the receiver of the stator. Apart from the disadvantage of the large number of transmitter diodes and the additional cost of manufacture of the diode carrier, the quantity of data that can be transferred is in principle limited to about two Mbit/s. This is because owing to the rotation of the receiver diode the signal path formed between the ring of transmitter diodes and the receiver diode is not continuous but is spatially amplitudemodulated.
围绕转子侧的接收器二极管。通过 13 个二极管（12 个发射器和 1 个接收器）在转子和定子之间传输信息涉及高昂的结构支出。位于旋转轴上的传输路径，可以使用一个发射器和一个接收器进行简单的直接传输，该路径已经被转子的发射器和定子的接收器占据。除了发射器二极管数量多和二极管载波制造成本增加的缺点外，可以传输的数据量原则上仅限于 2 Mbit/s 左右。这是因为由于接收器二极管的旋转，发射器二极管环和接收器二极管之间形成的信号路径不是连续的，而是在空间上调幅的。

OBJECT OF THE INVENTION  发明目的

It is an object of the invention to provide an apparatus for the transfer of information from and to rotating systems which avoids the disadvantages of mechanical, contact and radio transfer, which makes use of the advantages of a direct optical signal transfer for both directions of transfer and consequently can transmit a larger quantity of data, and which in itself involves low manufacturing costs.
本发明的目的在于提供一种用于从旋转系统传输信息和向旋转系统传输信息的装置，该装置避免了机械、接触和无线电传输的缺点，它利用了两个传输方向的直接光信号传输的优点，因此可以传输更多的数据， 这本身就涉及低制造成本。

SUMMARY OF THE INVENTION  发明内容

To this end, an apparatus according to the invention for the bidirectional transfer of information comprises in each case: at least one rotating component; a further component; receivers on the respective components, said receivers facing one another in groups on the axis of rotation of the rotating component; and transmitters fitted on said components eccentrically with regard to the axis of rotation and directed towards the corresponding receivers.
为此，根据本发明的用于信息双向传输的装置在每种情况下包括：至少一个旋转部件;另一个组件;接收器位于各个部件上，所述接收器在旋转部件的旋转轴上成组相对;以及相对于旋转轴偏心安装在所述部件上并指向相应接收器的发射器。
This solution of the problem is based on the principle of positioning both the receiver of the rotating unit and the receiver of the non-rotating unit on the axis of rotation or a prolongation thereof, and of arranging the respective transmitters in the region of the axis of rotation with their transmission beam directed towards the opposite receiver and inclined with regard to the axis of rotation.
该问题的这种解决方案基于以下原理：将旋转单元的接收器和非旋转单元的接收器都定位在旋转轴或其延长轴上，并将相应的发射器布置在旋转轴的区域内，使其传输光束指向相反的接收器并相对于旋转轴倾斜。
In the apparatus according to the invention the receivers located on the axis of rotation of the systems that rotate relative to one another face one another. In contrast to the conventional transfer systems, in the apparatus according to the invention no transfer path is set up directly on the axis of rotation.
在根据本发明的装置中，位于相对旋转的系统旋转轴上的接收器彼此相对。与传统的传输系统相比，在根据本发明的设备中，没有直接在旋转轴上设置传输路径。
The signals are in each case transmitted from one or more transmitters to the receiver located opposite. This transfer can take place in two directions, since in contrast to the known systems using central transfer the axis of rotation, as described above, is not occupied. In accordance with the invention the transmitters have a transmitting beam which is inclined with regard to the axis of rotation and is directed towards the receiver opposite.
在每种情况下，信号都从一个或多个发射器传输到位于对面的接收器。这种转移可以在两个方向上进行，因为与使用中心转移的已知系统相比，如上所述，旋转轴没有被占用。根据本发明，发射器具有相对于旋转轴倾斜并指向相反接收器的发射光束。
The transmitters can be arranged directly in the vicinity of the receiver, so that the aperture angle of the receiver opposite them remains small.
发射器可以直接布置在接收器附近，以便对面接收器的孔径角保持较小。
Preferably the receiver and transmitter are connected to pulse code modulators, which enable coding of the transmitted signal to be performed.
优选地，接收器和发射器连接到脉冲编码调制器，从而能够对发射信号进行编码。
The transfer system can be used with particular advantage in the case of optical rotation transmitters for rotating measuring and information systems. Here the whole apparatus can, in the case of the transmitter described above, be
传输系统特别适用于用于旋转测量和信息系统的旋光变送器。在这里，对于上述发射器，整个设备可以是
accommodated inside the transformer ring. Consequently an expensive ring of diodes for the transmission of signals to the rotor can be dispensed with. Furthermore, the apparatus according to the invention offers the advantage that the quantity of data that can be transmitted is the same in both directions and is far superior to the conventional systems. In addition, the transfer of data takes place simultaneously in both directions and continuously. Moreover the exchange of parts presents no problems, owing to the simple construction of the transmitter and receiver units.
安装在变压器环内。因此，可以省去用于将信号传输到转子的昂贵二极管环。此外，根据本发明的设备提供的优点是可以传输的数据量在两个方向上相同，并且远远优于传统系统。此外，数据传输在两个方向上同时进行，并且是连续的。此外，由于发射器和接收器单元的结构简单，零件更换没有问题。

DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT OF THE INVENTION
本发明的优选实施例的详细说明

As shown in FIG. 1, the information transfer takes place at the interface of a rotor 1 with a stator 2 in the region of the rotor axis 6. The transmitter is located in the centre 9 of a pot-type core transformer 3 . A receiver 4 of the stator 2 and a receiver 5 of the rotor 1 are arranged facing one another on the rotor axis 6 6 6\mathbf{6}. Outside the rotor axis 6 6 6\mathbf{6}, and eccentrically to the rotor axis, a stator transmitter diode 7 is located in the region of a stator receiver diode 4 and a rotor transmitter diode 8 8 8\mathbf{8} is located in the region of the rotor receiver diode 5 . The transmitter diodes 7 , 8 7 , 8 7,8\mathbf{7 , 8} are inclined at such an angle that the optical signal of the transmitter is directed towards the respective receiver diode 4 , 5 4 , 5 4,5\mathbf{4}, 5 located opposite it on the axis of rotation 6 6 6\mathbf{6}. The receiver diodes 4 , 5 4 , 5 4,5\mathbf{4 , 5} have an aperture angle sufficient for the reception of signals of the eccentrically arranged transmitter diodes. As a result of the eccentric position of the transmitter diodes 7 , 8 7 , 8 7,8\mathbf{7 , 8} the transmitter diode 8 moves from side to side as the rotor rotates, while the beam transmitted from it remains continuously directed towards the receiver diode 4 of the stator. At the same time the beam transmitted from the transmitter diode 7 of the stator remains constantly directed towards the rotating receiver diode 5 of the rotor. Within the protected centre 9 of the pot-like core transformer 3 the optical information transfer can proceed without any problems and free from interference. By pulse code modulation by means of the pulse code modulator modules 10 , 11 , 12 , 13 10 , 11 , 12 , 13 10,11,12,1310,11,12,13 which are connected to the transmitter diodes 7,8 and to the receiver diodes 4,5 the input and output signals are coded for optimum transfer.
如图 1 所示，信息传输发生在转子轴 6 区域中的转子 1 与定子 2 的界面处。发射器位于罐式铁芯变压器 3 的中心 9 中。定子 2 的接收器 4 和转子 1 的接收器 5 在转子轴 6 6 6\mathbf{6} 线上彼此相对设置。在转子轴 6 6 6\mathbf{6} 外，且偏心于转子轴，定子发射二极管7位于定子接收二极管4的区域内，转子发射二极管 8 8 8\mathbf{8} 位于转子接收二极管5的区域内。发射器二极管 7 , 8 7 , 8 7,8\mathbf{7 , 8} 以这样的角度倾斜，使得发射器的光信号指向 4 , 5 4 , 5 4,5\mathbf{4}, 5 位于旋转 6 6 6\mathbf{6} 轴上与其相对的相应接收器二极管。接收器二极管 4 , 5 4 , 5 4,5\mathbf{4 , 5} 的孔径角足以接收偏心布置的发射器二极管的信号。由于发射二极管的偏心位置 7 , 8 7 , 8 7,8\mathbf{7 , 8} ，发射二极管 8 随着转子的旋转而从一侧移动到另一侧，而从它发射的光束仍然持续地指向定子的接收器二极管 4。同时，从定子的发射二极管 7 发射的光束始终指向转子的旋转接收器二极管 5。在罐式铁芯变压器 3 的受保护中心 9 内，光信息传输可以毫无问题地进行，并且不受干扰。通过脉冲编码调制，通过连接到发射器二极管 7,8 和接收器二极管 4,5 的脉冲编码调制器模块 10 , 11 , 12 , 13 10 , 11 , 12 , 13 10,11,12,1310,11,12,13 ，输入和输出信号被编码以实现最佳传输。
Through this construction a high rate of bidirectional data transfer can be achieved, and at the same time the constructional outlay is reduced to a minimum.
通过这种结构，可以实现高速率的双向数据传输，同时将结构支出降至最低。
