Description

The invention relates to a satellite channel preparation System according to the preamble of claim 1.

To not only terre about community antenna systems stric, but also Pro broadcast via satellite To be able to receive grams are corresponding food and Reception systems including the associated translators necessary.

For feeding satellite programs into an existing one Home distribution system for community reception systems who which is therefore related to satellite channel processing systems.

Those received from a satellite antenna, for example Satellite programs are made according to their polarization placed on two input distribution panels. Between these Incoming distribution fields and an outgoing collective field the individual channel strips are switched  Power supply unit supplied with electrical energy and via control lines from a preferably mikropro processor-controlled control unit can be controlled.

The control unit can be used for the individual channel strips the relevant parameters can be set to the various programs broadcast via satellite to lay certain channels.

These channel-specific output frequencies will be via the output busbar into the network of a Ge community receiving distribution system.

For the construction of such a satellite channel processing there are different concepts.

A so-called satellite compact processing is known, for example system according to the Kathrein brochure F009 / 50/292 / AI / PF. It is a complete system with one unit Fixed chassis and housing cover. The electrical Power supply for the electronic control and the the channel strips comprising demodulators and modulators are mounted on prepared slots. That too The input and output collector are hard-wired and provided at a predetermined location. The control of the Channel strips are made using a cable tape.

Although such systems have proven themselves in practice have, this system is for an expansion for several Ka not specified. If need be at most one additional satellite compact processing system added the.

In order to meet varia To be more, for example, is according to the Kathrein-Pro Spect "Kathrein IF converter UFO" according to the prospectus  C 473 100881 already an arrangement of IF frequency conversion zern in cassette design have been proposed to the two mounting rails mounted in parallel on the wall can be permanently installed. You can do this if necessary add another cassette parallel to the existing ones be added. In this embodiment, all are Plug connections, level controls and indicator lights on the Front of the device and are located directly in the Field of vision of the user. This is supposed to signal flow be easy to see through. In addition, all necessary hands should be handles carried out from the front during assembly and maintenance can be.

There are also modular sewage treatment plants became known. In a known system, a network device as well as a control circuit and beyond that one individual, in cassette form channel strips on a Mounting plate built up. They can be connected via a wire bus electrical supply and control lines on the The top of the individual channel strips. At the front and rear face are the coaxial from the input distribution and output collective field plugged. A maximum of six channels can be mounted on the mounting plate trains are plugged on. This number is not enough accordingly, a new sewer preparation system must be included complete assembly chassis and power supply installed become.

In the case of an embodiment which deviates from this, it is provided hen that the mounting plate a power supply by up to four Amplifier units for separate channel amplification can record. The supply voltage is on the pla tine on the back of the mounting plate.

Each duct unit can be placed directly on the mounting plate be plugged in without wiring the power supply  would be required. The coaxial plug for connection that from the input distributor and that to the output collector leading coaxial cables are on a front face exposed attached.

A generic satellite channel processing system is also from the Grundig brochure Grundig STC 800 or the Ver publication "The universal complete head-end station" in DE-Z "Funkschau 1992, Issue 5, pages 94, 95" known. It consists of a modular plug-in system for up to eight channel strips that have an additional one on the chassis built-up microprocessor control controlled and over a central network unit with electrical energy ver be worried. Finally, an output signal is through grinding provided.

In this embodiment, too, are the setting elements not in the cassette, but in the central tax office device provided for the individual channel strips. The electri cal power supply and the connection of the control line on the back of the channel strips, which are in a box-shaped box on a floor forming there, d. H. the chassis below can be plugged on. It is also provided one to the individual channel strips rear exit busbar on which the channel strips are attachable. However, points each cassette has a front coaxial connector to here the coaxial coming from the input distribution panel to connect cables. But above all, despite the modula the entire plug-in system Size limited by the related rigid box shape, which are closed by a front cover can.

Finally, systems (Teleste) are also known have been, each one for one or more cas suitable base module is used, on which the cassette in question also for mechanical fixation is attachable. The individual modules are each in one direction of assembly can be plugged together, with the Plug connections ensure the power supply.  

The basic module also serves as a collective field. Everything However, the input signals are via separate above or front coaxial connections to the individual cas set fed. In addition, the hiring takes place at the Cassettes also separately, so that not targeted in Output collective field according to the different requirements different interconnection made can be. Otherwise, the respective plug-in clocks the signal transmission from one basic module to the next due to the large number of contacts.

The object of the present invention is therefore based on proceeding from the last but one position of the Technology to create a satellite channel processing plant that are optimally suited to the needs and handling Conditions can be adjusted and improved Handling allows.

The task is according to the invention in accordance with solved claim 1 specified features. Advantageous Ausge Events of the invention are set out in the dependent claims give.

The present invention is a completely modular Satellite channel conditioning system created.

Instead of the assembly and Distribution base is now an Montageun invention terbau provided, which is separate and separate from one Distribution level is provided. In other words, they are an electrical connection from the input distribution panel to the channel modules or from these to the output ver Distribution module producing distribution panel as separate construction groups placed on the assembly base.

According to the invention, all interfaces between the  the individual channel preparation serving channel modules for Incoming distribution field and outgoing collective field as well the energy supply and where applicable NEN control lines together on the back, d. H. the Bottom of the cassette modules can be provided.

This results in the simplest assembly and disassembly. If necessary, additional assembly modules can be added and then the required distribution or Collection modules put on and finally the Kas set modules can be connected by simply plugging them on. This makes replacement just as easy guarantee individual channel modules in the event of problems or defects continuous

The assembly sub Construction is also modularly structured according to the invention and for this purpose includes strings that can be strung together Single mounting modules. If necessary, the mounting base by adding one or more assembly modules in be expanded in at least one direction.

In a preferred development of the invention, the Control lines as one over the individual assembly modules wire bus running away. Can prefer here also protruding upwards in its narrow side and isolated from each other on the individual assembly modules held wire tapes are used, which when opening plug a channel module with a corresponding one trained contact plug on the back of the channel module be contacted automatically. This has the advantage that each channel module directly with this Steuerlei tion bus can be contacted electrically without a variety of electrical transmission current contact plugs are necessary, for example the control line signals from one module to another transfer.  

In one embodiment of the invention, the distribution ermodule designed as distribution blocks that on the Mounting blocks are installed and those on their top with contact connections for plugging in and for electrical Contacting the channel modules are provided.

In an alternative embodiment, the distribution lermodule be designed as distribution blocks, the Coaxial cable line sections with the concerned Places pre-adjustable connectors are connected, on which then on the individual channel modules on the Bottom provided plug connections under electrical Contacting can be plugged on.

In Fig. 1 is a schematic plan view of the about structural configuration is the satellite channel, a processing plant, finally, the electric components, however, without the apparent only in FIG. 2, shown the substructure representing assembly modules.

The satellite channel shown in FIGS. 1 and 2 treatment plant comprises a sample accommodated in a common housing in the illustrated execution elec tric energy supply 1 and an electronic STEU erungsschaltung 3, over which in the illustrated execution 1 ten channel modules 5, for example in Fig. In cassette form can be controlled via a power supply and control line bus 7 .

All channel modules 5 are connected to the central controller 3 , for example, via a three-wire bus. All parameters of a single channel strip are carried out via the central operator unit of the electrical control circuit 3 and are displayed, for example, via a display device 3 'seen there. Channel-specific setting values can, for example, be stored in an EEPROM of the channel strip and stored device-specifically in the central controller.

In the exemplary embodiment shown, the system further comprises an input distribution field 11 and an output collecting field 13 . In the external circuitry shown in Fig. 1, for example, the programs received from a satellite antenna 15 from a satellite according to the different horizontal or vertical polarization via two subordinate coaxial antenna lines 17 ', 17 ''are fed to the input distribution panel 11 . In the exemplary embodiment shown, this includes the input distribution field 11 distribution blocks 11 ', which can be selected according to needs. In the exemplary embodiment shown, a first distribution block 11 'for connection to four-channel modules 5 is connected via an outer coaxial connector 19 to an antenna cable 17 '.

The second antenna line 17 '' leads via an outer distributor or branch 21 also to two nachgeord Neten distribution blocks 11 ', namely a distribution block 11 ' also for connecting four channel modules 5 and another distribution block 11 'for connecting only two channel Module 5 .

On the output combiner 13 is shown exporting approximately example, a first collection block 13 'for the connection of eight channel modules 5 and a second collection block 13' for connection of the two in Fig. 1 righthand channel modu len 5 provided on outer coaxial 19 and an adding or merging stage 23 leads together and merges via a subordinate further adding and merging stage 25 with the further programs received via a terrestrial antenna 26 for feeding into a subordinate community antenna system.

The con structive structure is explained in greater detail below, in particular with reference to FIG. 2. Parts of the system shown in Fig. 1 are omitted.

From Fig. 1 and 2 as a whole is seen that the Sa telliten channel treatment system is mounted on a pedestal or a wall 27. For this purpose, for example, in the exemplary embodiment according to FIG. 2, two rails 29 , which were arranged in the lateral direction from one another and could be selected as desired or extended by extension pieces, were provided, which are screwed, for example, onto the wall 27 underneath.

An assembly base 31 initially rests on these assembly rails. This mounting base 31 consists of individual mounting modules 33 , which can be expanded at least in one mounting direction by adding a further mounting module 33 . As a result, the mounting base 31 can be expanded according to the needs and requirements of practice. The maximum size and the maximum number of channel modules is ultimately only limited by the design requirements and circumstances and by the power supply parameters of the electrical power supply 1 and / or the electronic control circuit 3 .

The individual mounting modules 33 can be firmly installed on the mounting rails 29 by means of screws 37 seated in bores 35 . By means of plug projections 41 or sockets 43 , each provided with rotational symmetry in the direction of attachment 39 , a plug connection which serves for the structural stability for the spacing positioning of two adjacent mounting modules can also be created. In principle, any positive or non-positive connections can be provided from one assembly module to the next, which, for example, can be secured to one another from above when the channel modules 5 are removed by screwing in screws, or can be released again by loosening the screws.

The mounting modules 33 have a step 45 on the outside transversely to the mounting direction 39 , on which at least the channel modules 5 can also be seated on their outer lower edge in a mounted position.

Adjacent to the edges or steps 45 , the distribution blocks 11 'can be used. Depending on requirements, available, the connection of two, three four, five etc. channel modules 5 serving distributor blocks 11 'can be used and, for example, when the entire system is enlarged by adding a further distributor block 11 ' or by replacing z. B. two existing manifold blocks 11 'with a smaller number of connections to be replaced by a higher number of connections for several channel modules.

In the exemplary embodiment according to FIG. 2, the steps 45 are each spaced apart in the mounting direction 39 from an adjacent step 45 of an adjacent assembly module 39 , the distance 47 corresponding at least approximately to the diameter of a coaxial connection 19 . The distributor blocks ke 11 'are preferably used directly under contact or at least directly adjacent to the inner wall side of the steps 45 inside the mounting modules 33 . About just if not shown screw or clamp connections, the individual manifold blocks 11 'can be mounted at the relevant points on the mounting base 31 . Even additional, possibly only purely mechanical plug-in connections can facilitate a grid-like, very clear assignment and adjustment of the distributor blocks 11 '.

For the embodiment shown in Fig. 1 and 2 can also be seen that the length of the manifold blocks 11 'within wide limits arbitrarily large chosen and in each case the width may cover several assembly modules 33rd

In the transverse direction to the mounting direction 39 , the dimensioning of the distributor blocks 11 'is comparatively small in order to leave space in the middle of the mounting modules 33 for laying various cables.

Finally, it is also apparent from Fig. 2 that the height of the distributor blocks 11 'can correspond, for example, to the height of the steps 45 .

Approximately in the middle on the mounting blocks 33 , the above-mentioned power supply and / or control line bus 7 is provided. For this purpose, in the exemplary embodiment shown, a bus support 51 is provided approximately in the middle of each mounting block 33 , on which the lines are laid over several mounting blocks.

As can be seen in particular from the enlarged detail cross-section of Fig. 3, preferably band-shaped wires in vertical parallel alignment for the power supply line 7 'or the control line 7 ''can be used, which according to the choice of material at a distance from each other in the bus support 51 these are kept outstanding upwards. When additional modules are added, the individual wires 7 ', 7 ''can be replaced by longer ones, or new wire sections serving as extensions can be brought into contact with one or more of the bus supports 51 over the entire surface with the already laid wires or in other ways Way contacted by appropriate bus connector to accomplish an extension.

According to the local conditions and needs, the corresponding number of mounting modules 33 is installed before the installation of the parallel mounting rails 29 or further added if necessary. Subsequently, the manifold blocks 11 'and (in Fig. 2 for the sake of clarity not yet illustrated manifolds ke 13 ' on the side to the manifold blocks 11 'opposite side) are built according to size and need, and then finally after the laying of Data bus 7 to plug in the corresponding number of channel modules 5 . For this purpose, the channel modules 5 each at their opposite areas on the underside plug connections 55 ( Fig. 3), which can be inserted into corresponding plug connections 57 in the distribution blocks 11 '. In the area of the distribution bus 7 , the aforementioned bus connector 51 is provided on the underside 59 of the channel modules 5 , so that the complete connection can be made via the common interface 63 thus formed simply by plugging in the channel modules 5 . The corresponding control of the individual channel module 5 can then take place via the central electronic control circuit 3 .

Of course, the individual mounting modules 33 can also be designed with double or even triple or generally multiple widths, for example, in order to always be able to accommodate two, three or even more channel modules 5, for example.

In Fig. 4 a modification to Fig. 1 to 3 is shown insofar as here the distributor blocks 11 '' or the collecting blocks 13 '' on the mounting modules 33 are installed at another location, if necessary also in several mounting modules 33 overlapping position, wherein the manifold blocks 11 '' in this embodiment, connected via coaxial cable sections 67 having seated at the end of the cord pieces 67 plug connections 69th In this embodiment, the plug connections 69 and are accordingly pre-adjusted in positions 33 prepared in the assembly modules. For example, corresponding drilling stanchions can be provided in the mounting modules 33 , into which the underside of the plug connections can be mechanically inserted or locked. In this embodiment, the channel modules 5 are then plugged into the plug connections 69 with their plug connections located below.

In this embodiment, a choice can be made between differently prepared distribution blocks 11 ', namely those which, for example, are provided with two, four, six, etc. or odd-numbered connections 69 at the end of cable pieces 67 .

The statements made above for the manifold blocks 11 'apply equally to the Darge shown in Fig. 4 collection blocks 13 ''. In both cases, the wiring takes place within the assembly space within the assembly module 33 , the coaxial antenna cables here being routed to the corresponding distribution block 11 '' or from the corresponding collector block 13 '' to the communal system in the interior of the assembly modules 33 . Of course, the distribution blocks according to FIGS . 1 and 2 and alternatively to FIG. 4 on the input and output sides can also be used alternately. The cables shown in FIG. 1 leading to the plug connections 19 are not yet connected in the illustration according to FIG. 4.

Finally, the mentioned manifold blocks and / or the channel modules 5 can be securely mounted on the mounting base by suitable clamp or screw connections. Basically sufficient is a firm anchoring of the channel modules 5 on the mounting base 31 , that is, the mounting modules 33 , since the manifold and collecting blocks mounted on the intermediate level are held captive in between anyway. Especially with a plug connection on the mounting base and appropriate dimensioning of the height of the distributor and collecting blocks, these are automatically secured by the channel modules 5 placed above them.

Due to the entire structure with the common single interface or level 63 , all the connections below are secured and shielded and can also be protected against improper intervention if necessary (lead sealing).

The illustrated in Fig. 1 electrical power supply 1 and the electronic control circuit 3 can be anchored in the pitch on the mounting rails 29 and built on. Basically, the arrangement can also be of the type that this energy supply and the control circuit device are also built on the mounting modules.

The interface 63 shown in FIG. 3 does not necessarily have to lie in a height plane. The individual plug connections and the contact plug for contacting the power supply and control lines 7 can each be provided at different heights. Nevertheless, there is a functionally fully effective connection of a channel module by plugging it over the section plane, which - as stated - can also be step-shaped, in any case for all connections on the back of the channel modules.

In Fig. 5 and 6 so far a certain modification of the embodiments shown in FIGS. 2 to 4, as the steps are provided 45 even with an outer upwardly extended guide 45 'here. The Füh tion 45 'consists of a vertically extending and inward, ie to point to the inserted channel module 5 , the groove-shaped recess 45 '', in which the vertical end face of the channel module when inserting and removing ge leads and to contributes to a tipping stability. The Füh tion 45 'can be seen over the entire height of the channel modules 5 or only a part height considered sufficient. Finally, in the side region of the channel modules 5 adjacent to the U-shaped guides 45 '', the bores 71 shown only in broken lines in FIG. 6 can be provided, by means of which screws 73 fix the individual channel modules 5 to the mounting module 33 can. The screws 73 preferably engage in the area of the step 45 in a hole made in the axial extension of the bore 71 in the channel module 5 in the step 45 in the mounting module 33 .
