Method and system for detecting and digitally transmitting analog output measured quantities of a number of transducers

摘要

process for capture and digital broadcast analog ausgangsmessgru00f6u00dfen several converters to a protection or field device, the analog ausgangsmessgru00f6u00dfen each transformer (ect1...evtbb) with a sampling rate, by a factor of (m) higher than the mindestabtastrate, digital measures (md) converts and transmits with the factor (m) is an integer divisor of the number (n) of the filterkoeffizienten each of the fir filter (fir) with the value of 1 filterkoeffizienten in a datenkonzentrator (26) for each transducer (ect1...evtbb).the digital measure (md) as a datenkonzentrator wire transfer, and from each transducer (ect1...evtbb) assigned buffer (buf1) with a clock (clock) data in the fir filters (fir) vorgeordnete nachzwischenspeicher (buf2), with the clock (clock) from the synchronzeichen of each wire and the fixed time of a taktgenerators formed.in the datenkonzentrator is by means of a multiplexer (27) from the fir filters (fir) downstream ausgangszwischenspeichern (buf3) with a sendetelegramm in their sampling rate reduced digital measures of the transducer to the protection or formed and transferred to the field device.
