Exhaust Gas Measuring Technique With Decentralized Intelligence 845113
Up to now it was necessary that with the exhaust gas measuring
the recall of the tests (ECE, CVS, Japan etc.) was coordinated by a
master computer who collected the data, processed them and recorded
them via the peripheral equipment or that an operator undertook
these functions.
In a modern processing system the control and evaluation expense
in the central computer is reduced by the reasonable application of
microprocessors in the different decentralized units such as
analysing systems, CVS-systems, driver's aid and so on.
For this purpose in the individual units are executed
independently in the following operations: - sequence control -
independent execution of calibrations - automatic switching over of
the measuring range - conversion of the measuring values into
physical values - linearization
Specified interfaces and standardized transmission software
facilitate the interplay of the units with a master computer.
In addition a further step for the displacement of the computer
intelligence is realized by fitting up the analyzers contained in
the units with own microprocessors
