Abstract

A monitoring system for identifying the closing of a particular switch in a two-wire detector circuit across which a number of similar switches (S1 to Sn) are connected in parallel employs a transponder (G1 to Gn) in series with each switch (S1 to Sn). The individual switches (S1 to Sn) are operated by the various control elements of eg. a complex textile machine to indicate a specific functional failure. The closing of a switch (S1 to Sn) connects an antenna-coupled HF power source (T) of e.g. 128kHz in a remote read-out terminal (L) to the respective transponder (G1 to Gn) via the two-wire circuit (A) which then transmits a coded identity signal at a different frequency eg. 64kHz back to the station (L) via the antenna coupling for evaluation and display. USE/ADVANTAGE - Rnables a large number of integrated functions to be remotely monitored by a reliable low-cost system using standard commercial components and only a single two-core linking cable.

Description

Die vorliegende Erfindung betrifft eine Schaltungsanord­ nung nach Patentanspruch 1.The present invention relates to a circuit arrangement according to claim 1.

Bei vielen Maschinen, z. B. im Textilbereich oder hydrauli­ schen Bereich gibt es eine Vielzahl von annähernd gleich­ artigen Vorrichtungen wie z. B. Düsen, Ösen, Ventile oder dergleichen die zusammenwirken und deren einzelner Ausfall bereits zu schwerwiegenden Störungen führt.In many machines, e.g. B. in the textile sector or hydrauli There are a large number of approximately identical areas like devices such. B. nozzles, eyelets, valves or the like that work together and their individual failure already leads to serious disturbances.

Es ist bekannt eine Überwachung der einzelnen Vorrichtun­ gen z. B. derart vorzunehmen, daß jede Vorrichtung einen Schalter mit Lampe aufweist, was eine Beobachtung vor Ort erfordert oder daß man über mehrachsige Kabel eine zentrale Überwachung der den ein­ zelnen Vorrichtungen zugeordneten Schaltern ermöglicht. Solche Überwachungseinrichtungen sind verhältnismäßig auf­ wendig und schwer lokalisierbar, insbesondere wenn die An­ zahl der zu überwachenden Vorrichtungen sehr groß ist.Monitoring of the individual devices is known against z. B. make such that each device Has switch with lamp,  what an observation on site requires or that one can Multi-axis cables central monitoring of the one allows individual devices associated switches. Such monitoring devices are proportionate to manoeuvrable and difficult to locate, especially if the An number of devices to be monitored is very large.

Weiterhin sind sogenannte Identifikationssysteme bekannt, die ein sogenanntes Lesegerät und eine Vielzahl von Trans­ pondern vorsehen um z. B. Tiere oder Waren zu überwachen. Ein wesentliches Teil der in allgemeinen sehr kleinen Transponder sind mit Kenndaten programmierte Speicher­ chips, die bei Zuführung von Energie, z. B. Hochfrequenze­ nergie die gespeicherten Daten als elektrische Daten aus­ lesen lassen.So-called identification systems are also known, which is a so-called reader and a variety of Trans provide ponder around z. B. to monitor animals or goods. Much of the generally very small Transponders are memories programmed with characteristic data chips that are supplied with energy, e.g. B. radio frequency energy stored data as electrical data let read.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde eine eingangs genannte Schaltungsanordnung so zu verbessern, daß sie bei geringem Aufwand mit einer Zweidrahtleitung eine zentrale Überwachung des Betriebszustandes einer großen Anzahl von Vorrichtungen ermöglicht. Diese Aufgabe wird durch die im Kennzeichen des Patentanspruches 1 ange­ gebenen Merkmale gelöst.The present invention is based on the object to improve the circuit arrangement mentioned at the beginning, that with little effort with a two-wire line a central monitoring of the operating status of a allows a large number of devices. This task is indicated by the in the characterizing part of claim 1 given characteristics solved.

Ein wesentlicher Vorteil der Erfindung wird darin gesehen, daß es mit Hilfe der aus der Technik der Identifikations­ systeme bekannten Bauteilen, wie z. B. programmierbare Speicherchips, mit geringem Aufwand möglich wird, die ein­ zelnen Vorrichtungen komplexer Maschinen wie z. B. Spinnau­ tomaten und dergleichen von einer zentralen Stelle aus zu überwachen, so daß bei Ausfall einer Vorrichtung eine umge­ hende Behebung des Schadens ermöglicht wird.An essential advantage of the invention is seen in that with the help of identification technology systems known components such. B. programmable Memory chips, with little effort, becomes possible individual devices of complex machines such. B. Spinnau tomatoes and the like from a central location monitor so that when a device fails, a vice correcting the damage is made possible.

Anhand der in den Fig. 1 bis 3 schematisch dargestell­ ten Ausführungsbeispiele wird die Erfindung nachfolgend näher erläutert.The invention is explained in more detail below with reference to the exemplary embodiments schematically shown in FIGS. 1 to 3.

In der Fig. 1 ist eine Zweidrahtleitung A dargestellt, die mit einer Vielzahl von parallel liegenden Schalter­ schleifen 1, 2 . . . n verbunden ist. Jede Schalterschleife 1, 2 . . n weist einen Schalter S1, S2 - Sn der in Reihe mit ei­ nem Signalgeber G1, G2 in Gn liegt. Jede Schalterschleife 1, 2 . . n sei beispielsweise einer Düse eines Spinnautomaten in der Weise zugeordnet, daß bei Ausfall einer Düse der zugeordnete Schalter schließt.In Fig. 1, a two-wire line A is shown, which loop with a plurality of switches 1 , 2 in parallel. . . n is connected. Each switch loop 1 , 2 . . n has a switch S 1 , S 2 - S n which is in series with a signal generator G 1 , G 2 in G n . Each switch loop 1 , 2 . . For example, let n be assigned to a nozzle of an automatic spinning machine in such a way that the associated switch closes in the event of a nozzle failure.

Die Signalgeber G1 bis Gn sind bevorzugt programmierte elektronische Speicherchips, wobei jeder Geber G1 - Gn eine andere Kennung entsprechend der zugeordneten Düse aufweist. Bei Schließen eines der Schalter S1 bis Sn wird dem entsprechenden Geber G1 - Gn elektrische Energie zuge­ führt, dieser dadurch aktiviert und dazu veranlaßt seine Speicherkennung in Form eines Identifikationssignals auf die Zweidrahtleitung a abzugeben.The signal transmitters G 1 to G n are preferably programmed electronic memory chips, each transmitter G 1 - G n having a different identifier in accordance with the assigned nozzle. When one of the switches S 1 to S n to the corresponding donor G 1 - G n leads electric power supplied, it is activated and thereby to cause its memory tag in the form of an identification signal to the two-wire line a dispense.

Die Zweidrahtleitung A ist z. B. induktiv über eine Anten­ nenkennordnung einem Lesegerät L gekoppelt. Das Lesegerät wertet das Identifikationssignal aus und zeigt z. B. die ausgefallene Düse an. Das Lesegerät besitzt zweckmäßig, wie bei Identifikationssystemen bekannt, zusätzlich einen Hochfrequenzsender, der über die Kennkoppelanordnung T elektrische Hochfrequenzenergie auf die Zweidrahtleitung A aufschaltet, die bei geschlossenem Schalter S1 - Sn den zugehörigen Signalgeber G1 - Gn mit Energie versorgt, ak­ tiviert und zur Abgabe des Identifikationssignals veran­ laßt. Die Sendefrequenzen des Lesegerätes L und der Si­ gnalgeber G1 - Gn sind unterschiedlich und/oder zeitlich gestaffelt, wie dies bei Identifikationssystemen bekannt ist. Die Sendefrequenz des Lesegerätes L kann beispiels­ weise 128 kHz und die des Signalgebers G1 - Gn 64 kHz be­ tragen.The two-wire line A is e.g. B. inductively coupled via an antenna nenkennordnung a reader L. The reader evaluates the identification signal and shows z. B. the failed nozzle. The reader advantageously has, as is known in identification systems, an additional high-frequency transmitter which, via the identification coupling arrangement T, applies high-frequency electrical energy to the two-wire line A, which supplies the associated signal generator G 1 - G n with energy when the switch S 1 - S n is closed and activated and caused to emit the identification signal. The transmission frequencies of the reading device L and the signal generator G 1 - G n are different and / or staggered in time, as is known in identification systems. The transmission frequency of the reader L can be, for example, 128 kHz and that of the signal generator G 1 - G n 64 kHz.

In den Fig. 2 und 3 sind Ausführungsbeispiele von Schalterschleifen 1 gezeigt. In Fig. 2 liegt parallel zum Signalgeber G1 noch eine Reihenschaltung von zwei Zenerdi­ oden. In Fig. 3 ist dem Signalgeber G1 und den Zenerdi­ oden Z noch eine Kapazität zur Impedanzanpassung parallel geschaltet. Den Zenerdioden kommt die Aufgabe eines Über­ spannungsschutzes zu.In FIGS. 2 and 3 embodiments are shown of switch loops 1. In Fig. 2 is parallel to the signal generator G 1 still a series connection of two Zener diodes. In Fig. 3, the signal generator G 1 and the Zener diodes Z a capacitance for impedance matching is connected in parallel. The Zener diodes have the task of overvoltage protection.
