Definitions
- This task is accomplished by a circuit arrangement according to spell 1 solved.
- Fig. 6 shows a circuit for generating an opposite signal.
- the evaluation device receives via the data output 19, which, for. B. can be implemented in the form of a serial interface or a data bus, digital signals, which are obtained from the analog input signals i, ... and N '..., which are provided by Sensofen, for example pressure sensors.
- the evaluation device cannot assign any signal errors that falsify the digital signals to an error source, e.g. B. Errors in the analog-to-digital converter 1, since the evaluation device receives only the superimposition of the digital signals with all errors occurring on the signal path as an input signal. As errors such. B. Inaccuracies of the sensors or static errors of the analog-Z digital converters 1, 2 are indicated. see.
- the static errors of the analog-Z-digital converters 1, 2 are combined to form an overall error, which is placed around the ideal transmission curve 20 in the form of an error band, represented by the deviations + x LSB and -x LSB in FIG. 2. If, for example, it is assumed that only static errors in the analog-Z-digital converters 1, 2 and inaccuracies in the sensors can be present, suitable measures, e.g. B. addition, from the static errors and the inaccuracies around the ideal transmission curve 20, a tolerance range is defined, which is suitable for the detection of a signal error. With this procedure, however, all signals that are within the tolerance range count as error-free values.
- the circuit arrangement described in FIG. 1 is completely redundant and, as described above, is spatially separated by the choice of the layout.
- the input signals and their redundant signals can neither in the analog multiplexers 3, 4, nor in the analog-Z digital converters 1, 2 and in the result registers 8, 9 due to an error in the (common) address logic of the control logic 5 affect.
- the digital multiplexers 6, 7 it is different, since the signals from the result registers 8, 9 on a data output, for. B. data bus, serial interface, etc., can be placed. This is done e.g. B. by time windows in which a signal is transmitted in a first time window and the signal redundant to the signal is transmitted in a second time window.
