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
