    专利说明:

    The invention relates to a device for image and / or data transmission from a linearly guided on a rope or rail assembly camera assembly comprising a camera-carrying trolley, which can be driven along the cable or rail assembly in two or four directions of movement, wherein for data transmission, a data cable , Preferably, an optical fiber cable is provided.
    Rope or track-guided camera arrangements are often used for broadcasting sporting events or cultural events. This is often a cableway system with two supporting cables arranged next to one another and a traction cable arranged centrally therebetween, by means of which a trolley can be moved along the two supporting cables. The provision of two suspension ropes prevents the camera from swaying, and it also increases safety, because if one of the ropes breaks, the camera will not crash.
    Thus, the camera can be pulled in both directions, the traction cable is designed as a circulating cable with at least one deflecting pulley at the two ends of the supporting cables, with a strand running between the two traction cables and is fixed to the trolley and wherein the second strand at a distance thereof parallel running back. By driving one of the deflection pulleys, the traction cable and thus the trolley are driven. In order to meet the requirements of sporting events, the trolley must be correspondingly strong acceleration and deceleration, which accordingly strong engines and heavy-duty pull ropes are used.
    The trolley carries the camera as well as facilities for stabilization and the necessary energy supply. The image data is usually transmitted by radio to the ground and from there in a conventional manner on data cables.
    The transmission by radio, however, has the disadvantage that it comes again and again to image disturbances (for example, if the allocated frequency is inadvertently shared by someone else), which is often noticed in live broadcasts and the television consumer.
    In addition, under certain circumstances, the transmission of image data by radio is not possible at all: in the case of very large events bottlenecks in the available radio frequencies for transmission may occur, or radio transmission is not permitted due to safety regulations. In the presence of important personalities, such as state presidents, all radio traffic is blocked by means of jammers for security reasons.
    As an alternative, the possibility to connect the camera by means of a data cable, which should be a fiber optic cable for good quality. To prevent the data cable sagging to the ground, it must be wound on a cable drum or unwound from it when the camera moves. The rotation of the cable drum must be exactly synchronized with the pull rope of the trolley. Even slight differences in the synchronization (for example due to the unavoidable slip of the pull rope) can lead to an unacceptably high tension in the data cable or to an unacceptably high slack. In the case of the light guides preferably used, a relatively low tensile stress is already sufficient to stretch the sensitive cable and to impair or interrupt the data transmission. Conversely, it may happen that the data cable is wound up too slowly (or too fast), causing it to sag too much (possibly to the ground), disrupting the event. For the cable drum, a further drive (in addition to the traction cable drive) is required in this fictitious embodiment. Such systems are therefore often expensive and prone to errors and can even lead to disruption of the event.
    It is an object of the present invention to provide an apparatus for transferring images and data from a camera array guided linearly on a cable or track assembly which overcomes the existing problems and enables transmission of image data by data cable in a simple, trouble-free and cost-effective manner.
    3
    This object is achieved by a device of the type mentioned in the present invention that the data cable is connected to the camera and is guided away from the trolley first in one of the two directions of movement along the cable or rail assembly to a cable drum, the cable drum an interface for data transmission, and that a second cable is provided which is guided away from the trolley first in the other direction along the cable or rail assembly to the same cable drum, the data cable and the second cable are wound in opposite directions on the cable drum, so that the data cable with together form a circulating rope together the second rope.
    The term " rope " should be understood here in the physical sense, so to designate an elastic element that is suitable for the transmission of tensile forces. Also a data cable is in this sense a " rope ". Therefore, the data cable is also referred to as " first rope " designated. According to the invention, there are two additional ropes (in addition to the traction cable (s) and traction cable (s)) which, in addition to the traction cable, result in a further circulating cable which is interrupted on the cable drum (ie has two free ends) ), so that the signal can be tapped from the data cable.
    By providing a single cable drum this can be passively formed as a companion drum. Depending on the direction in which the trolley is moved, the two cables are correspondingly unwound and unwound: When the data cable is unwound, this turns the cable drum so that the second rope is wound up, and when the second rope is unwound, this turns the cable drum so that the data cable is wound up. In this way, excessive slack is not possible, it is only important that the two ropes are about the same weight and about the same diameter.
    A motor for synchronizing the winding mechanism of the data cable · with that of the pull rope is not necessary, since the running over the entire system sum of the cable lengths remains the same at each point.
    • fr fr t t fr fr fr fr fr · · · «·· fr fr« I · «fr 4
    Another feature of the invention is that the second cable is also a data cable, preferably an optical cable, which is also connected to the camera. This has the advantage that even if a data cable is damaged, uninterrupted transmission via the other data cable is still possible.
    According to a further feature of the invention, it is provided that the cable drum is drivable by means of a motor. With correct control of the motor, the forces can be reduced to the ropes, because the ropes then no longer have to accelerate the cable drum. Nevertheless, even with incorrect control of the motor excessive slack of the ropes is excluded.
    It is also a feature of the invention that parallel to the axis of the cable drum for each rope per a pulley arrangement is provided, each one edge stationary stationary pulley deflects the respective cable on a second, along a guide parallel to the axis of the cable drum slidably disposed pulley and the second movable deflection roller deflects the respective cable for winding onto the cable drum or for unwinding from the cable drum, wherein the two Umlenkrollenanordnungen are arranged in opposite directions, so that the stationary guide rollers are arranged on opposite sides of the device, and wherein the movement of the movable guide rollers is coupled ,
    A deflection arrangement is necessary in order to place the two cables exactly on the cable drum and thus to avoid an undesired overlapping of the two cables.
    Due to the necessary bias of the ropes, tensile forces occur which affect the pulley arrangements.
    These tensile forces are problematic in the case of the movable deflection rollers in that they can be moved much more easily in one direction (or even have to be braked) than in the other direction. Therefore, a powerful drive for a single pulley would be necessary. By providing a
    Coupling between the two pulleys cancel out these opposing forces, so that a common drive can be less powerful and in particular must not be able to apply braking forces.
    Another feature of the invention is that the two movable pulleys are movable by means of a respective spindle parallel to the axis of the cable drum, wherein the two spindles by a separate or a common power transmission, for example by a toothed belt, are driven, wherein the threads of the spindles have the same direction of travel, so move the moving pulleys in driving the spindles in the same direction.
    In one possible embodiment, the power transmission of the two spindles is connected to a common motor which drives the two spindles. The motor must be synchronized in this case with the movement of the cable drum. It is advantageous that the ratio between rotation of the cable drum and rotation of the spindles can be easily changed (for example, if cables with different diameters are used).
    In an alternative embodiment, the power transmission is connected to the axis of the cable drum, which thus drives the two spindles. This eliminates a separate drive.
    Finally, it is a feature of the invention that the cable drum has a cable-carrying cylinder and two rotatably mounted axle sections, wherein the cylinder is connected to the two axle sections in each case via spring assemblies. In the case of the rope or track assemblies used for cameras, it is mandatory to provide an emergency braking device. During emergency braking, the trolley stops abruptly (at around 20 m / s2). Due to the inertia of the cable drum, this suddenly causes an increased tensile force on the ropes, so that they could be damaged. For this reason, it is advantageous to provide a damping. Due to the bearing of the cable-carrying cylinder via spring assemblies, not all the mass of the device acts immediately on the ropes during emergency braking, but only •. Φ * · Φ Φ «6 the mass of the cable-carrying cylinder; the influence of the mass of the remaining parts is absorbed by the springs and distributed over a longer period.
    The invention will now be described with reference to the accompanying drawings, wherein
    Fig. 1 shows a schematic view of the principle according to the invention with a cable drum in front view;
    Fig. 2 shows the cable drum in side view;
    Fig. 3 shows the cable drum with Seillegevorrichtung;
    Fig. 4 shows a side view of the device according to Fig. 3; and
    Fig. 5 is a sectional schematic detail view of a storage of the cable drum.
    In Fig. 1 the arrangement according to the invention is shown schematically. A trolley 21, to which a camera 22 is attached, is movable on carrying ropes (not shown). To drive a rotating traction cable (not shown) is used.
    From the camera 22, a data cable 3 goes away, which runs first in one of the two directions of movement parallel to the support cables and then guided over a deflection plate 23 and a Seillegevorrichtung 27 to a cable drum 2. Furthermore, in the other direction of movement, a cable 4 goes away, which initially also runs parallel to the suspension cables and is deflected via two deflection pulleys 24, 25 first in the opposite direction and finally guided over another deflection pulley 26 and the cable guide device 27 to the same cable drum 2. The cable 4 is intended to have the same diameter and the same weight per length as the data cable 3. It may be designed in particular as a further data cable.
    As can be seen from Fig. 2, the two cables 3, 4 are each wound up to the axial ends of the cable drum 2 on this. The data cable 3 is guided at the axial end of the cable drum 2 to the axis where a rotary coupler 28 is located to feed the signals in a fixed data cable. · * ··· ♦ t · · · · * * * * * * * * * * * * * * * * * * * * * • * «« «* * * *«
    The cables 3, 4 are wound in turns next to each other on the cable drum 2, wherein the winding sense of the two cables 3, 4 is in opposite directions. In the central region of the cable drum 2, the two cables 3, 4 are deducted from the cable drum 2, the exact location depends on where just the trolley is with the camera.
    When the trolley 21 moves to the right as viewed in FIG. 1, the data cable 3 is retightened and the cable drum is set in a counterclockwise motion; thereby the cable 4 is wound up (and the data cable 3 unwound). The location (Fig. 2) where data cable 3 and cable 4 are withdrawn slowly moves to the left (the Seillegevorrich-device 27 is driven accordingly, as will be explained in more detail). Moves the trolley 21 - as seen in Figure 1 - to the left, the cable 4 is tightened and the cable drum is set in a clockwise motion; As a result, the data cable 3 is wound up. No matter how the trolley 21 is moved, data cable 3 and cable 4 always remain the same tension and do not hang through, without the need for special control.
    With reference to FIGS. 3-5, the cable drum 2 will now be explained in more detail with the cable gland device 27. The cable drum 2 is rotatably mounted in a device 1. About the Seillegevorrichtung 27 each data cable 3 and the second cable 4 are guided to the cable drum 2 and on this gegengleich same or unwound.
    So that the two cables 3, 4 do not come to lie one above the other on the cable drum, the rope-laying device 27 is provided, which has a deflection roller arrangement consisting of a stationary deflection roller 5 and a movable deflection roller 6 for each cable 3, 4. Each cable 3, 4 is brought to the device via a respective stationary deflection roller 5. The stationary deflection roller 5 transfers the cable 3, 4 to a respective movable deflection roller 6 and this transfers the respective cable 3, 4, to the cable drum 2. The movable deflection rollers 6 are guided on guide rods 7 which are parallel to the axis 10 ··· ♦ * φφφφ * · • * ♦ • »· * φ ♦« · 8 of the cable drum 2 are arranged. The movable guide rollers 6 are each moved by means of a spindle 8. The two spindles 8 are connected in the embodiment shown with a common toothed belt 11 with a motor 9 (see FIG. 4). Due to the prestressing of the cables 3, 4, tensile forces occur, which are shown in FIG. 3 and FIG. 4 by force arrows. The forces of the two cables 3, 4 act opposite. By the timing belt 11 as a common power transmission, these forces cancel because they are essentially the same size. Thereby, the load on the engine 9 can be minimized. In a preferred embodiment, the power transmission can also be connected to the axis 10 of the cable drum 2 and thus driven by it. The advantage would be that it can be dispensed with entirely an additional engine.
    Fig. 5 shows a possible attenuation of the cable drum 2 in order to partially absorb the inertial forces in the event of emergency braking of the trolley 21 and to load the sensitive data cable 3 less. The cable drum 2 essentially comprises a cylinder 12, on which the two cables 3, 4 are wound, and two axle sections 13, which are rotatably mounted. The connection between the cylinder 12 and Achsabschnitten 13 via spring assemblies 14, which allow for an abrupt braking a certain rotation of the cylinder 12 relative to the Achsabschnitten 13 and thus contribute to the damping of the force peak.
    An advantage of the invention is that the data cable 3 and the second cable 4 are independent of the actual cable car system subject to authorization. That even if the data cable 3 is damaged during an event, it can be exchanged without requiring a new authorization of the cable car system. (A new permit would not be possible during an event due to time constraints).
