Summary:

Up to now it was necessary that with the exhaust gas measuringthe recall of the tests (ECE, CVS, Japan et cetera) was coordinated by amaster computer who collected the data, processed them and recordedthem via the peripheral equipment or that an operator undertookthese functions.In a modern processing system the control and evaluation expensein the central computer is reduced by the reasonable application ofmicroprocessors in the different decentralized units such asanalysing systems, CVS-systems, driver's aid and so on.For this purpose in the individual units are executedindependently in the following operations: - sequence control -independent execution of calibrations - automatic switching over ofthe measuring range - conversion of the measuring values intophysical values - linearizationSpecified interfaces and standardized transmission softwarefacilitate the interplay of the units with a master computer.In addition a further step for the displacement of the computerintelligence is realized by fitting up the analyzers contained inthe units with own microprocessors
