Abstract
Description
Diese Erfindung betrifft die Verbesserung eines Zeitzeichenempfängers für Funkuhren, der in der bekannten Form einen abgestimmten Antennenkreis, einen Filter, einen geregelten Verstärker und einen Amplitudendemodulator besitzt.This Invention relates to the improvement of a time signal receiver for radio clocks, in the known form a tuned antenna circuit, one Filter, a regulated amplifier and has an amplitude demodulator.
Diese Empfänger werden als integrierte Schaltungen hergestellt und für den Empfang der Zeitzeichensender, wie z.B. DCF77, MSF, WWVB und JJY benutzt, um mit einer digitalen Signalverarbeitung, z.B. einem Mikrocontroller, Zeituhren zu stellen oder zu synchronisieren. Diese Uhren werden auch als Funkuhren bezeichnet.This receiver are manufactured as integrated circuits and for reception the time signal transmitter, e.g. DCF77, MSF, WWVB and JJY used, to use digital signal processing, e.g. a microcontroller, To set or synchronize time clocks. These clocks are too referred to as radio clocks.
Der
Zeitzeichensender senkt im Sekundentakt die Amplitude über eine
Pulslänge,
die aus der digitalen Codierung der Übertragungsinformation abgeleitet
wird, ab. Somit hat der Zeitzeichenempfänger die Aufgabe, die digitalen
Signale für
die digitale Signalverarbeitung der Funkuhr zu gewinnen. Durch Störungen aus
der Umgebung und aus der Nutzung der Funkuhren selbst, wie z.B.
bei Armbanduhren durch deren Bewegung sehr starke, kurzzeitige Feldstärkeschwankungen
auftreten, wird die Empfangsmöglichkeit
der Zeitzeichensignale eingeschränkt. Derartige
Zeitzeichenempfänger

In diesem bisherigen Lösungskonzept werden die demodulierten Zeitzeicheninformationen durch einen Zeitzeichenempfänger bereitgestellt, dessen verschiedene Funktionsparameter durch seine Schaltungstechnik fixiert sind. Somit sind, unabhängig von den äußeren Bedingungen, dessen Funktionen immer gleich.In this previous solution concept the demodulated time signal information is provided by a time signal receiver whose different functional parameters fixed by its circuit technology are. Thus, are independent from the external conditions, whose functions are always the same.
Die Nachteile dieser bisher bekannten Lösungen von Zeitzeichenempfängern bestehen darin, dass der Empfänger fest eingestellte Funktionsparameter hat und somit keine Möglichkeit besteht, auf sich ändernde äußere Bedingungen und Störeinflüsse variabel einzugehen. Das heißt, die Optimierung der Empfängerparameter dieser Zeitzeichenempfänger kann nur zu einer angenommenen Bedingung zum Zeitpunkt seiner Konstruktion erfolgen.The Disadvantages of these previously known solutions for time signal receivers exist in that the recipient has fixed function parameters and therefore no possibility insists on changing external conditions and interference influences variable enter into. This means, the optimization of the receiver parameters this time signal receiver can only be on an assumed condition at the time of its construction respectively.

So steht z. B. die Aufgabe zur Verbesserung der Störungsunterdrückung im starken Störsignalumfeld, die Demodulation mit der Signallagenerkennung so zu verschieben, dass die Störungen im Signal minimiert sind.So stands z. B. the task of improving interference suppression in strong interference signal environment, to shift the demodulation with the signal position detection so that the interference are minimized in the signal.
