Abstract

Die Erfindung betrifft eine zur Überwachung eines elektronischen Sicherungselementes (2) in einer Abfragezone (3), bestehend aus einer Sendeeinrichtung (4), die zumindest ein periodisches Abfragesignal in die Abfragezone (3) aussendet, wobei das Abfragesignal das Sicherungselement (2) zur Aussendung eines Erkennungssignals anregt, einer Empfangseinrichtung (5) mit zumindest einem Empfangskanal, die das Erkennungssignal empfängt, und einer Rechen-/Regeleinheit (7), die die von der Empfangseinrichtung (5) empfangenen Signale auswertet und bei Identifizierung des Sicherungselementes (2) einen Alarm auslöst.The invention relates to a for monitoring a electronic security element (2) in a query zone (3), consisting of a transmission device (4), the at least one periodic interrogation signal in the interrogation zone (3) transmits, the query signal the Security element (2) for sending a Excitation signal excites a receiving device (5) with at least one receiving channel that the detection signal receives, and a computing / control unit (7), which of the the received device (5) evaluates received signals and upon identification of the securing element (2) Alarm triggers.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung (1) vorzuschlagen, die das Erkennen von Artikeln (6), die mit elektronisch detektierbaren Sicherungselementen (2) ausgestattet sind, innerhalb einer Abfragezone (3) verbessert.The invention has for its object a device (1) propose the recognition of articles (6) that with electronically detectable security elements (2) are equipped within a query zone (3) improved.

Die Aufgabe wird dadurch gelöst, daß die Rechen-/Regeleinheit (7) anhand der empfangenen Signale (r(s)) der einzelnen Empfangskanäle Störpulse erkennt, von den Störpulsen in einem selbst-lernenden Prozeß eine entsprechende Signalform erstellt und die empfangenen Signale (r(s)) von den ermittelten Störpulsen befreit.

Figure 00000001
The object is achieved in that the computing / control unit (7) detects interference pulses on the basis of the received signals (r (s)) of the individual receiving channels, creates a corresponding signal form from the interference pulses in a self-learning process, and the received signals (r (s)) freed from the determined interference pulses.
