Abstract

Verfahren zum Erfassen und digitalen Übertragen von analogen Ausgangsmessgrößen mehrerer Wandler zu einem Schutz- oder Feldgerät die analogen Ausgangsmessgrößen jedes Wandlers (ECT1...EVTBB) mit einer Abtastrate, die um einen Faktor (m) höher als die Mindestabtastrate ist, in digitale Messgrößen (Md) umsetzt und überträgt, wobei der Faktor (m) ein ganzzahliger Teiler der Anzahl (n) der Filterkoeffizienten jeweils eines FIR-Filters (FIR) mit Filterkoeffizienten des Wertes 1 in einem Datenkonzentrator (26) für jeden Wandler (ECT1...EVTBB) ist. Die digitalen Messgrößen (Md) werden als Telegramm zu einem Datenkonzentrator übertragen, und aus jedem Wandler (ECT1...EVTBB) zugeordneten Zwischenspeichern (Buf1) mit einem Takt (Clock) Daten in den FIR-Filtern (FIR) vorgeordnete Nachzwischenspeicher (Buf2) übernommen, wobei der Takt (Clock) aus dem Synchronzeichen des jeweiligen Telegramms und dem festen Takt eines Taktgenerators gebildet. In dem Datenkonzentrator wird mittels eines Multiplexers (27) aus den FIR-Filtern (FIR) nachgeordneten Ausgangszwischenspeichern (Buf3) ein Sendetelegramm mit in ihrer Abtastrate reduzierten digitalen Messgrößen der Wandler gebildet und zu dem Schutz- oder Feldgerät übertragen.

Method for detecting and digitally transmitting analog output variables of several converters to a protective or field device, the analog output variables of each converter (ECT1 ... EVTBB) with a sampling rate that is higher than the minimum sampling rate by a factor (m) into digital measured variables ( Md), where the factor (m) is an integer divisor of the number (n) of the filter coefficients of each one FIR filter (FIR) with filter coefficients of value 1 in a data concentrator (26) for each transducer (ECT1 ... EVTBB ). The digital measured quantities (Md) are transmitted as a telegram to a data concentrator, and from each converter (ECT1 ... EVTBB) associated buffers (Buf1) with a clock (Clock) data in the FIR filters (FIR) upstream post-buffer (Buf2) adopted, the clock (clock) from the sync of the respective telegram and the fixed clock of a clock generator formed. In the data concentrator, a transmission telegram with digital variables of the transducers reduced in their sampling rate is formed by means of a multiplexer (27) from the FIR filters (FIR) downstream output buffer memories (Buf3) and transmitted to the protection or field device.
