Description

PATENTANMELDUNG PATENT APPLICATION
Schaltungsanordnung zur Auswertung von Fernsteuersignalen.Circuit arrangement for evaluating remote control signals.
Die Erfindung geht aus von einer Schaltungsanordnung zur Auswertung von PCM-Fernsteuersignalen mit Hilfe eines programmierbaren Mikroprozessors , in dessen Programm unter anderem in regelmäßiger, zeitlichen Abständen Abfragezyklen untergebracht sind, deren Dauer kleiner als der kürzeste zeitliche Abstand zweier aufeinanderfolgender Fernsteuerimpulse sind, die über einen Vorverstärker an den Mikroprozessor angelegt sind.The invention is based on a circuit arrangement for evaluating PCM remote control signals with the aid of a programmable microprocessor, in the program of which, inter alia, query cycles are accommodated at regular, time intervals, the duration of which is shorter than the shortest time interval between two successive remote control pulses, which are transmitted via a preamplifier are applied to the microprocessor.
Insbesonere Fernsteuersignale müssen vom Mikroprozessor bevorzugt abgearbeitet werden, da diese zu beliebigen Zeiten während des Programmablaufs auftreten kennen. Es muß daher unmittelbar bei Auftreten von Fernsteuersignalen das vom Mikroprozessor abzuarbeitende Programm unterbrochen werden, damit die Information des Fernsteuerbefehls detektiert werden kann, deshalb werden die Fernsteuersignale über einer, besonderen Eingang, den Interrupt-Eingang, an den Mikroprozessor gelegt. Bei vielen Applikationen mit Mikroprozessoren müssen auch weitere zeitkritische Signale verarbeitet werden, so daß z.B. Mikroprozessoren mit mehreren Interrupt-Eingängen benötigt werden, die jedoch teuer sind. Der Erfindung liegt die Aufgabe zugrunde, wenigstens für die Fernsteuersignale diesen Interrupt-Eingang zu umgehen, Diese Aufgabe wird durch die im Patentanspruch angegebene Erfindung gelöst.Remote control signals, in particular, must be processed preferentially by the microprocessor, since they are known to occur at any time during program execution. The program to be processed by the microprocessor must therefore be interrupted immediately when remote control signals occur, so that the information of the remote control command can be detected. Therefore, the remote control signals are applied to the microprocessor via a special input, the interrupt input. In many applications with microprocessors, further time-critical signals must also be processed, so that, for example, microprocessors with several interrupt inputs are required, which, however, are expensive. The object of the invention is to bypass this interrupt input at least for the remote control signals. This object is achieved by the invention specified in the patent claim.
Die Erfindung bringt den Vorteil, daß das Fernsteuersignal an einen beliebigen I/O - Port angelegt werden kann und der Mikroprozessor das zeitlich beliebig auftretende Fernsteuersignal erkennt. So können einfache Mikroprozessoren verwendet werden.The invention has the advantage that the remote control signal can be applied to any I / O port and the microprocessor recognizes the remote control signal that occurs at any time. So simple microprocessors can be used.
Geht man davon aus, daß die Information der Fernsteuersignale in den unterschiedlichen Impulsabständen liegt, z.B. bedeutet ein kurzer zeitlicher Abstand zweier Impulse eine binäre 1 und doppelt so langer Abstand der Impulse eine binäre 0, und daß die Dauer der regelmäßig auftretenden Abfragezyklen kleiner ist als der kürzeste Impulsabstand der Fernsteuersignale, genügt es die eintreffenden Impulse bis zum Auftreten des nächsten Abfragezykluses zwischenzuspeichern, so daß der Mikroprozessor diese ohne Unterbrechung des Programms auswerten kann.If one assumes that the information of the remote control signals lies in the different pulse intervals, e.g. If a short time interval between two pulses means a binary 1 and twice as long a distance of the pulses a binary 0, and that the duration of the regularly occurring polling cycles is shorter than the shortest pulse spacing of the remote control signals, it is sufficient to temporarily store the incoming pulses until the next polling cycle occurs , so that the microprocessor can evaluate them without interrupting the program.
Der Abfragezeitpunkt, der während der Zeiträume A auftritt, dient dazu, den Fort für die Fernsteuersignale abzufragen.The polling time, which occurs during the periods A, serves to poll the fort for the remote control signals.
Wie eine derartige Speicherung bewerkstelligt werden kann, wird nachstehend mit Hilfe der Zeichnung erläutert. Figur 1 zeigt ein Beispiel mit einer monostabilen Kippstufe;How such storage can be accomplished is explained below with the aid of the drawing. Figure 1 shows an example with a monostable multivibrator;
Figur 2 zeigt ein Impulsdiagramm zu Figur 1;Figure 2 shows a timing diagram for Figure 1;
Figur 3 zeigt ein Eeispiel mit einer bistabilen Kippstufe;Figure 3 shows an example with a bistable flip-flop;
Figur 4 zeigt ein Impulsciagramm zu Figur 3.FIG. 4 shows a pulse diagram for FIG. 3.
In Figur 1 empfängt und verstärkt ein Vorverstärker 1 die von einem Fernsteuersender 2 gesendeten Signale, welche über eine monostabile Kippstufe 3 an einen beliebigen Eingaiigsport I an den Mikroprozessor 4 gelegt sind. Die Kippzeit t der monostabilen Kippstufe 3 ist derart gewählt, daß der zu einem beliebigen Zeitpunkt to bis t4 eintreffende Fernsteuerimpuls F derart verbreitert wird, daß er in den nächstfolgenden Abfragezyklus A des Mikroprozessors fällt. Der Abfragezyklus A wiederholt sich regelmäßig nach den Abständen T während des Programmablaufs P, wie in Figur 2 gezeigt ist. Die Impulse F werden zu Impulsen F' umgeformt und kennen während der Abfragezeiträume A erkannt werden.In FIG. 1, a preamplifier 1 receives and amplifies the signals transmitted by a remote control transmitter 2, which signals are applied to the microprocessor 4 via a monostable multivibrator 3 at any input port I. The flip time t of the monostable flip-flop 3 is selected such that the remote control pulse F arriving at any time to to t4 is broadened in such a way that it falls within the next polling cycle A of the microprocessor. The query cycle A is repeated regularly after the intervals T during the program sequence P, as shown in FIG. 2. The pulses F are converted into pulses F 'and are known during the query periods A.
In Figur 3 ist der Ausgang des Vorverstärkers 1 an den Setzeingang S einer bistabilen Kippstufe 5 geschaltet. Der Q-Ausgang geht an den Eingangsport I des Mikroprozessors 4, welcher während des Abfragezyklusses A einen Rücksetzimpuls über den Ausgangsport 0 an den Rücksetzeingang R der bistabilen Kippstufe 5 abgibt. Diese Verhältnisse sind in Figur 4 dargestellt. Zu Zeit punkten t1 bis t3 wird die bistabile Kippstufe 5 jeweils gesetzt und zu den Zeitpunkten to bis t3' zurückgesetzt. Auf diese Weise werden die Fernsteuersignale ebenfalls jeweils bis zur Abfrage durch den Mikroprozessor 4 gespeichert. In Figure 3, the output of the preamplifier 1 is connected to the set input S of a bistable multivibrator 5. The Q output goes to the input port I of the microprocessor 4, which emits a reset pulse via the output port 0 to the reset input R of the bistable multivibrator 5 during the polling cycle A. These relationships are shown in FIG. 4. At time points t1 to t3, the bistable flip-flop 5 is set and reset at times to to t3 '. In this way, the remote control signals are also stored until queried by the microprocessor 4.
