Abstract (en)
[origin: US2003011491A1] To develop a method according to WO 01/45232 in such a manner that it supplies good results in every case, in a method for detecting and digitally transmitting measured analog output values of a number of transducers to a protection or field device, the measured analog output values of each transducer (ECT1 . . . EVTBB) are converted into measured digital values (Md) at a sampling rate which is higher by a factor (m) than the minimum sampling rate, and are transmitted, the factor (m) being an integer divider of the number (n) of the filter coefficients of in each case one FIR filter (FIR) with filter coefficients of the value 1 in a data concentrator (26) for each transducer (ECT1 . . . EVTBB). The measured digital values (Md) are transmitted as a message to a data concentrator and from buffers (Buf1) associated with each transducer (ECT1 . . . EVTBB), data are transferred with a clock pulse into post-buffers (Buf2) preceding the FIR filters (FIR), the clock pulse being formed from the synchronous character of the respective message and the fixed clock of a clock generator. In the data concentrator, a transmit message with measured digital values of the transducers with reduced sampling rate are formed from output buffers (Buf3) following the FIR filters (FIR) by means of a multiplexer (27) and transmitted to the protection or field device.
