Abstract
Un mélangeur d'impulsions de synchronisation convertit les signaux en provenance des neuf sorties (1, 2, 3, 5, 6, 7, 8, 13, 14) d'une carte VGA de sorte que seuls trois câbles coaxiaux (16, 17, 18) soient requis pour retransmettre ces signaux jusqu'à un commutateur vidéo ou à un moniteur RVB. Ce mélangeur d'impulsions de synchronisation se caractérise notamment par le fait que l'énergie électrique requise par le circuit électronique (20) qui mélange les impulsions de synchronisation verticale et horizontale est prélevée directement des impulsions de synchronisation verticale et horizontale. On peut ainsi éliminer des sources supplémentaires de courant et réduire considérablement les dimensions du mélangeur d'impulsions de synchronisation.A sync pulse mixer converts the signals from the nine outputs (1, 2, 3, 5, 6, 7, 8, 13, 14) of a VGA card so that only three coaxial cables (16, 17 , 18) are required to retransmit these signals to a video switcher or RGB monitor. This synchronization pulse mixer is characterized in particular by the fact that the electrical energy required by the electronic circuit (20) which mixes the vertical and horizontal synchronization pulses is taken directly from the vertical and horizontal synchronization pulses. It is thus possible to eliminate additional sources of current and considerably reduce the dimensions of the synchronization pulse mixer.
Description
SYNCHRONIMPULS-MISCHER OHNE STROMVERSORGUNG SYNCHRONOUS PULSE MIXER WITHOUT POWER
Bildschirmgeräte bilden einen wichtigen Bestandteil der Peripherie von Personalcomputern. Der entscheidende Vorteil der Bildschirmgeräte ist darin zu sehen, dass sie einen echten Dialog zwischen dem Benutzer und dem Personalcomputer ermöglichen. In einer Art Frage- und Antwortwechsel (inter¬ aktiver Eingabe- und Ausgabebetrieb) kann der Sachbearbeiter mit dem Personalcomputer Informationen direkt austauschen. Ein Anwendungsbereich für Personalcomputer mit Bildschirm¬ geräten ist der Börsen- und Devisenhandel. Der Sachbearbei¬ ter, welcher im Börsen- und Devisenhandel tätig ist, braucht für seine Arbeit verschiedene Informationen, wie aktuelle Aktienkurse oder Wechselkurse. Diese Informationen werden von einer zentralen Datenbank in den Personalcomputer einge- spiesen. Üblicherweise befindet sich diese zentrale Daten¬ bank nicht im gleichen Gebäude wie die Personalcomputer, sondern im Gebäude einer Firma, welche den Banken die nöti¬ gen Daten bereitstellt. Die Daten werden in diesem Fall über Telefonleitungen zu den entsprechenden Personalcomputern übermittelt.Display devices form an important part of the periphery of personal computers. The decisive advantage of the display devices is that they enable a real dialogue between the user and the personal computer. In a kind of question and answer change (interactive input and output operation), the clerk can exchange information directly with the personal computer. An area of application for personal computers with display devices is stock exchange and foreign exchange trading. The clerk who works in exchange and foreign exchange trading needs various information for his work, such as current share prices or exchange rates. This information is fed into the personal computer from a central database. This central database is usually not in the same building as the personal computer, but in the building of a company which provides the banks with the necessary data. In this case, the data are transmitted via telephone lines to the corresponding personal computers.
Der Sachbearbeiter kann nun interaktiv mit Hilfe einer Ta¬ statur und eines Bildschirmgerätes die von ihm benötigten Daten auswählen, worauf diese auf dem Bildschirm wieder¬ gegeben werden. Er kann zum Beispiel den Begriff "US-Dollar" eingeben, worauf auf dem Bildschirm der aktuelle Wechselkurs des US-Dollars erscheint.The clerk can now interactively select the data he needs using a keyboard and a screen device, whereupon these are displayed on the screen. For example, he can enter the term "US dollar" and the screen will display the current exchange rate of the US dollar.
Es ist bei Banken üblich, dass die Personalcomputer nicht direkt am Arbeitsplatz auf dem Schreibtisch stehen, sondern entweder im Keller oder aber im Zwischenboden untergebracht sind. Dadurch wird am Arbeitsplatz weniger Platz versperrt und die Wartung bzw. Datensicherung der Personalcomputer wird erleichtert.
Der Nachteil dieser Anordnung besteht darin, dass die Daten vom Personalcomputer über längere Distanzen mit Kabeln zu den Bildschirmgeräten geleitet werden müssen. Bei Distanzen von über 1,8 Metern musε man für eine qualitativ hochstehen¬ de Datenübertragung Koaxialkabel verwenden.It is common for banks that the personal computers are not directly on the desk at the workplace, but are either in the basement or in the mezzanine. As a result, less space is blocked at the workplace and maintenance or data backup of the personal computer is made easier. The disadvantage of this arrangement is that the data must be routed from the personal computer over long distances to the display devices with cables. At distances of over 1.8 meters, coaxial cables have to be used for high-quality data transmission.
Zur Darstellung von Daten auf einen Bildschirmgerät müssen die Signale, welche vom Prozessor des Personalcomputers aus- gegeben werden, aufgearbeitet werden. Diese Aufgabe wird von sogenannten Graphikkarten übernommen. Am häufigsten verwen¬ det man heute VGA-Karten (Video-Graphics-Adapter-Karten) . Das Übertragungsprinzip dieser Karten ist analog. Ihre Adap¬ ter (Ausgänge) besitzen 15polige Buchsen mit folgender Bele¬ gung:To display data on a monitor, the signals that are output by the processor of the personal computer must be processed. This task is performed by so-called graphics cards. VGA cards (video graphics adapter cards) are used most frequently today. The transfer principle of these cards is analog. Their adapters (outputs) have 15-pin sockets with the following assignment:
Kontakt 1: Signal für Rot Kontakt 6: Masse für RotContact 1: signal for red Contact 6: ground for red
Kontakt 13: Signal für Horizontal-Synchronisation Kontakt 14: Signal für Vertikal-Synchronisation Kontakt 5: Masse (digital) Kontakt 2: Signal für Grün Kontakt 7: Masse für Grün Kontakt 3: Signale für Blau Kontakt 8: Masse für BlauContact 13: signal for horizontal synchronization Contact 14: signal for vertical synchronization Contact 5: ground (digital) Contact 2: signal for green Contact 7: ground for green Contact 3: signals for blue Contact 8: ground for blue
Nimmt man die Signale direkt von diesen 15poligen Buchsen ab, benötigt man neun Leitungen. Zur Übermittlung der Video¬ signale zu einem Videoschalter oder einem RGB-Monitor ist es unumgänglich, die Anzahl der Leitungen zu reduzieren. Gemäss dem heutigen Stand der Technik sind Synchronimpuls- Mischer bekannt, welche die Signale von acht Leitungen der¬ artig umwandeln, dass zur Weiterleitung zu einem RGB-Monitor oder zu einem Videoschalter nur noch drei Koaxialkabel not¬ wendig sind. Dies wird dadurch erreicht, dass die Horizon- tal-Synchronimpulse, die Vertikal-Synchronimpulse und die Signale für Grün auf ein einziges Koaxialkabel gemischt werden. Die Signale für Rot und die Masse für Rot werden direkt auf ein weiteres Koaxialkabel, die Signale für Blau
und die Masse für Blau direkt auf ein drittes Koaxialkabel gegeben.If you take the signals directly from these 15-pin sockets, you need nine lines. To transmit the video signals to a video switch or an RGB monitor, it is essential to reduce the number of lines. According to the current state of the art, synchronous pulse mixers are known which convert the signals from eight lines in such a way that only three coaxial cables are required for forwarding to an RGB monitor or to a video switch. This is achieved by mixing the horizontal sync pulses, the vertical sync pulses and the green signals on a single coaxial cable. The signals for red and the ground for red are directly on another coaxial cable, the signals for blue and put the mass for blue directly on a third coaxial cable.
Der Nachteil der bekannten Synchronimpuls-Mischer besteht darin, dass ihre elektronische Schaltung eine separate Stromquelle benötigt. Dadurch ist der Platzbedarf dieser Synchronimpuls-Mischer sehr gross. Die elektronische Schal¬ tung und das Netzteil sind in einem relativ grossen Gehäuse untergebracht. Für den Anschluss dieser Synchronimpuls- Mischer am Netz benötigt man ausserdem eine zusätzliche, Netz-Steckdose und einen entsprechenden Stecker.The disadvantage of the known synchronous pulse mixers is that their electronic circuitry requires a separate current source. This means that the space required for these synchronous pulse mixers is very large. The electronic circuit and the power pack are housed in a relatively large housing. An additional mains socket and a corresponding plug are also required to connect these synchronous pulse mixers to the mains.
Die Erfindung stellt sich die Aufgabe, einen Synchronimpuls- Mischer zu schaffen, welcher in der Lage ist, die Signale der neun Ausgänge einer VGA-Karte derartig umzuwandeln, dass für ihre Weiterleitung nur noch drei Koaxialkabel notwendig sind und dessen elektronische Schaltung keine zusätzliche Stromquelle benötigt.The invention has for its object to provide a synchronous pulse mixer, which is able to convert the signals of the nine outputs of a VGA card in such a way that only three coaxial cables are necessary for their forwarding and the electronic circuit does not require an additional power source .
Die Aufgabe wird erfindungsgemäss mit Hilfe der Ausbildungε- merkmale nach dem kennzeichnenden Teil des Patentanspruches 1 gelöst.The object is achieved according to the invention with the aid of the training features according to the characterizing part of patent claim 1.
Die Erfindung besteht im wesentlichen darin, dass beim vor¬ geschlagenen Synchronimpuls-Mischer die elektrische Energie, welche von der elektronischen Schaltung benötigt wird, di¬ rekt vom Vertikal- und Horizontal-Synchronimpuls abgezweigt wird. Dadurch kann auf eine zusätzliche Stromquelle verzich¬ tet und der Synchronimpuls-Mischer wesentlich kleiner ge¬ staltet werden. Es zeigt:The invention consists essentially in the fact that in the proposed synchronous pulse mixer the electrical energy required by the electronic circuit is branched off directly from the vertical and horizontal synchronizing pulse. As a result, an additional current source can be dispensed with and the synchronizing pulse mixer can be made substantially smaller. It shows:

Beim vorgeschlagenen Synchronimpuls-Mischer ist das erste Koaxialkabel 16 direkt mit dem VGA-Ausgang 1 für die Signale
von Rot und dem VGA-Ausgang 6 für die Masse von Rot verbun¬ den. Der VGA-Ausgang 13 für den Horizontal-Synchronimpuls, der Ausgang 14 für den Vertikal-Synchronimpuls und der Aus¬ gang 5 für die entsprechende Masse sind an der elektroni¬ schen Schaltung 20 angeschlossen, welche den Horizontal- Synchronimpuls und den Vertikal-Synchronimpuls mischt und auf die gleiche Leitung wie das Signal für Grün, welches vom entsprechenden VGA-Ausgang 2 kommt, weitergibt. Auf die erste Leitung des zweiten Koaxialkabels 17 wird das kom¬ binierte Signal für die Vertikal-Synchronisation, für die Horizontal-Synchronisation und für Grün gegeben. Die zweite Leitung des zweiten Koaxialkabels 17 ist direkt mit dem VGA- Ausgang 7 für die Masse von Grün verbunden. Der Ausgang 3 des Signals für Blau und der Ausgang 8 für die Masse von Blau ist direkt mit dem dritten Koaxialkabel 18 verbunden. Zur Speisung der elektronischen Schaltung 20 wird ein Teil der Energie des Vertikal-Synchronimpulses und des Horizon- tal-Synchronimpulses abgezweigt, gleichgerichtet und ge¬ glättet. Der resultierende, elektrische Gleichstrom wird der elektronischen Schaltung 20 zugeführt.In the proposed synchronous pulse mixer, the first coaxial cable 16 is directly connected to the VGA output 1 for the signals of red and the VGA output 6 for the mass of red. The VGA output 13 for the horizontal synchronizing pulse, the output 14 for the vertical synchronizing pulse and the output 5 for the corresponding ground are connected to the electronic circuit 20 which mixes the horizontal synchronizing pulse and the vertical synchronizing pulse and on the same line as the signal for green, which comes from the corresponding VGA output 2. The combined signal for the vertical synchronization, for the horizontal synchronization and for green is given to the first line of the second coaxial cable 17. The second line of the second coaxial cable 17 is connected directly to the VGA output 7 for the mass of green. The output 3 of the signal for blue and the output 8 for the ground of blue is connected directly to the third coaxial cable 18. To supply the electronic circuit 20, part of the energy of the vertical synchronizing pulse and the horizontal synchronizing pulse is branched off, rectified and smoothed. The resulting electrical direct current is supplied to the electronic circuit 20.
Bei einer bevorzugten Ausbildungsart wird ein Teil des elek¬ trischen Vertikal- und Horizontalsynchronimpulses direkt hinter dem entsprechenden VGA-Ausgang 13, 14 über je eine Leitung 21 abgenommen, mit je einer Diode 22 gleichgerichtet und mit einem Kondensator 23 geglättet. Der geglättete Gleichstrom aus beiden Synchronimpulsen wird über eine ge¬ meinsame Leitung 24 der elektronischen Schaltung 20 zuge¬ führt.In a preferred embodiment, part of the electrical vertical and horizontal sync pulse is taken directly behind the corresponding VGA output 13, 14 via a line 21, rectified with a diode 22 and smoothed with a capacitor 23. The smoothed direct current from the two synchronizing pulses is supplied to the electronic circuit 20 via a common line 24.
Die elektronische Schaltung 20 zum Mischen der Horizontal- und Vertikal-Synchronimpulse ist vorzugsweise als inte¬ grierte Schaltung (IC) ausgebildet.The electronic circuit 20 for mixing the horizontal and vertical synchronizing pulses is preferably designed as an integrated circuit (IC).
Die Elektronik zur Abzweigung, Gleichrichtung und Glättung eines Teiles der elektrischen Energie der Horizontal- und Vertikal-Synchronimpulse ist in SMD-Technik gefertigt. Der vorgeschlagene Synchronimpuls-Mischer weist gegenüber
den bisher bekannten Synchronimpuls-Mischern wesentliche Vorteile auf.Er benötigt für die elektronische Schaltung 20 zum Mischen des Horizontal- und Vertikal-Synchronimpulses keine separate Stromquelle mehr. Dadurch kann er im Ver¬ gleich zu den bisher bekannten Synchronimpuls-Mischern we¬ sentlich kleiner gebaut werden. Dank dieser Miniaturisierung ist es nicht mehr notwendig, den Synchronimpuls-Mischer in den Personalcomputer einzubauen. Er kann extern angeschlos¬ sen werden.The electronics for branching, rectifying and smoothing part of the electrical energy of the horizontal and vertical synchronizing pulses is manufactured using SMD technology. The proposed sync pulse mixer faces the previously known sync pulse mixers have significant advantages. He no longer requires a separate power source for the electronic circuit 20 for mixing the horizontal and vertical sync pulse. As a result, it can be made considerably smaller than the previously known synchronous pulse mixers. Thanks to this miniaturization, it is no longer necessary to install the sync pulse mixer in the personal computer. It can be connected externally.
Im weiteren hat der vorgeschlagene Synchronimpuls-Mischer den Vorteil, dass für seine Speisung keine zusätzlichen Steckdosen und entsprechende Stecker bereitgestellt werden müssen.Furthermore, the proposed synchronous pulse mixer has the advantage that no additional sockets and corresponding plugs have to be provided for its supply.
Dank der oben erwähnten Vorteile wird der vorgeschlagenen Synchronimpuls-Mischers auf grosses Interesse stossen.
Thanks to the advantages mentioned above, the proposed synchronous pulse mixer will meet with great interest.
