Description

Die Erfindung betrifft eine Einrichtung zur Funktionskontrolle von Prüfanlagen und -geräten zur zerstörungsfreien Werkstoffprüfung mittels Ultraschall-, Wirbelstrom- oder Streuflußverfahren.The invention relates to a device for Functional control of test systems and devices for non-destructive material testing by means of Ultrasonic, eddy current or leakage flow processes.

Die Überprüfung derartiger Anlagen bzw. Geräte erfolgt heute üblicherweise mittels Testkörpern anhand der sichtbaren Funktionen wie Leuchtschirmsignale oder Diskriminatorausgangslampen.Such systems or devices are checked today usually using test specimens based on the visible functions such as fluorescent screen signals or Discriminator output lamps.

Überprüfungen der verdeckt arbeitenden Funktionen sind nur unter großem Zeit- und Meßgeräteaufwand möglich und erfordern einen hohen Ausbildungsstand des Überprüfungspersonals. Eine periodische Kontrolle der Prüfanlagen bzw. -geräte ist somit nicht im erforderlichen Maß durchführbar.Checks of the hidden functions are only possible with great expenditure of time and measuring equipment and require a high level of training in Inspection personnel. A periodic check of the Test systems and equipment is therefore not in the required measure feasible.

Aus "Balzers-Katalog" (1983, Quadrupol-Massenspektrometer QMG 511, Seite N 13 bis N16) ist ein Blockschaubild für eine Kontrolleinrichtung bekannt, mit der überprüft werden kann, ob bestimmte Bausteine ein- oder ausgeschaltet sind. Außerdem können auch in einzelnen Kanälen gepeicherte Werte überprüft werden.From "Balzers Catalog" (1983, Quadrupole mass spectrometer QMG 511, page N 13 to N16) is a block diagram for one Control device known to be checked can, whether certain blocks on or off are. It can also be used in individual channels stored values are checked.

Die Überprüfung und ggf. Korrektur von Meßsignalen ist auch aus der "Industriellen Meßtechnik" (Prof. Dr. P. Profos, Vulkan Verlag Essen, 1978 Seiten 221-229) bekannt. Hierbei werden allerdings vorher festgelegte Grenz- bzw. Modellwerte für den Vergleich mit gemessenen Werten benutzt.The checking and, if necessary, correction of measurement signals is also from "Industrial Metrology" (Prof. Dr. P. Profos, Vulkan Verlag Essen, 1978 pages 221-229) known. Here, however, are determined beforehand Limit or model values for comparison with measured values used.

Aufgabe der Erfindung ist es, umfassende Funktionskontrollen leicht anpaßbar an jede Prüfanlage bzw. an jedes Prüfgerät objektiv und reproduzierbar unter deutlicher Verringerung der Aufwandzeit und der Personalqualifikation durchzuführen. The object of the invention is comprehensive Functional controls can be easily adapted to any test system or on any test device objectively and reproducibly while significantly reducing the time and effort To carry out personnel qualifications.  

Die Aufgabe löst eine Einrichtung mit den kennzeichnenden Merkmalen des Anspruchs.The task is solved by a facility with the characteristic features of the claim.

Der grundsätzliche Unterschied der erfindungsgemäßen Einrichtung zum Stand der Technik besteht darin, daß den eigentlichen z. B. während der Untersuchung eines Prüf- oder Eichkörpers der Prüfanlage zugeführten Signalen nachgebildete zusätzliche Signale in einer besonderen Einrichtung erzeugt und die simulierten Signale und die Prüfungssignale gemeinsam bewertet werden. Damit läßt sich dann ermitteln, ob die Prüfanlage auf die Prüfsignale reagiert und ob sie diese Signale richtig auswertet.The fundamental difference between the invention Prior art device is that the actual z. B. during the investigation of a Test or calibration body fed to the test system Signals simulated additional signals in one generated special facility and the simulated Signals and the test signals evaluated together will. This can then be used to determine whether the Test system reacts to the test signals and whether they evaluates these signals correctly.

Ein Ausführungsbeispiel der Erfindung wird anhand der Fig. 1 ausführlich beschrieben. An embodiment of the invention is described in detail with reference to FIG. 1.

Die Zentraleinheit (1) enthält einen frei programmier­ baren Rechner mit Programm- und Datenspeicher der alle für eine Anlagen- bzw. Geräteüberprüfung notwendigen Schritte steuert.The central unit ( 1 ) contains a freely programmable computer with program and data memory which controls all the steps necessary for a system or device check.

In der Einheit 2 a werden alle notwendigen digitalen Signale erzeugt, die zur Herstellung der Prüfbereit­ schaft der Prüfanlage 4 notwendig sind.In unit 2 a , all the necessary digital signals are generated, which are necessary for the production of the test system 4 .

Einheit 3 a bereitet die von der Prüfanlage kommenden digitalen bzw. analogen Reaktionssignale auf.Unit 3 a processes the digital or analog reaction signals coming from the test system.

Innerhalb der Einheit 3 b erfolgt die Synchronisation der Testeinrichtung mit der Prüfanlage bzw. dem Prüf­ gerät 4.Within the unit 3 b , the test device is synchronized with the test system or the test device 4 .

Programmgesteuert wird nun von der Zentraleinheit 1 synchron mit der Prüfanlage bzw. dem Prüfgerät 4 in der Einheit 2 b ein für das jeweilige Prüfverfahren mög­ liches Prüfsignal erzeugt. Diese Prüfsignale können z. B. für eine Ultraschall-Prüfanlage variiert werden in der Amplitude, der Frequenz, der zeitlichen Lage bezüglich des Synchronimpulses, der zeitlichen Länge und der Häufigkeit ihres Auftretens.Is programmatically now from the central unit 1 in synchronization with the test system and the tester 4 in the unit 2 a b mög pending for the respective test methods test signal generated. These test signals can e.g. B. for an ultrasound test system can be varied in the amplitude, the frequency, the time position with respect to the synchronizing pulse, the time length and the frequency of their occurrence.

Die Reaktionssignale der Prüfanlage bzw. des Prüfgerätes 4 werden von der Zentraleinheit 1 bewertet. Das Ergebnis wird dem Bediener der Testeinrichtung auf einem Schreib- und Protokolliergerät 5 mitgeteilt. The reaction signals of the test system or the test device 4 are evaluated by the central unit 1 . The result is communicated to the operator of the test device on a writing and logging device 5 .

Bewertungskriterien werden zum Teil von der Testein­ richtung selbst ermittelt. Für die Daten der Analogver­ stärker in einer Ultraschall-Prüfanlage ist z. B. das Frequenzspektrum eines Ultraschall-Prüfkopfes 6 not­ wendig. Dazu wird von der Testeinrichtung das Hoch­ frequenzsignal des Ultraschall-Prüfkopfes 6 an der Anschlußklemme 7 abgenommen, digitalisiert und das Frequenzspektrum ermittelt. Daraus wird als Bewertungs­ kriterium die Minimalforderung an die Bandbreite der Analogverstärker einer Ultraschall-Prüfanlage abgeleitet.Evaluation criteria are determined in part by the test facility itself. For the data of the Analogver stronger in an ultrasound test system, for. B. the frequency spectrum of an ultrasonic probe 6 not agile. For this purpose, the high-frequency signal of the ultrasonic probe 6 is removed from the test device at the terminal 7 , digitized and the frequency spectrum is determined. From this, the minimum requirement for the bandwidth of the analog amplifiers of an ultrasound test system is derived as an evaluation criterion.
