WAYS OF PERFECTION OF MODERN SYSTEMS OF DATA GATHERING

Ghavoronkova M.S., Bondar S.N.

We work over creation of universal systems of data gathering for various applications, on the basis of offered external modules of increase of accuracy the analog-digital converter (ADC), such as: the sample and storage device; the device of formation of absolute value of signals; the device of formation of basic pressure; the device of correction of errors.

Scientific novelty of decisions offered by us consists that we work over increase of accuracy of the devices entering into block ADC and operations, realized by them, considering block ADC as difficult system. While neither among developers, nor in the technical literature to these operations it is not given proper attention. Developers of systems of data gathering simply use standard schemes of these devices, considering block ADC as «a black box».

We can realize two variants of such systems with use of the developed external modules of increase of accuracy ADC: on the basis of cheaper element base that will provide characteristics of our system, comparable with analogs. A principle: quality (accuracy) - too, the price - more low; or on the basis of the same element base that will provide increase of accuracy and efficiency of our system in comparison with analogs. A principle: quality (accuracy) - above, the price - a little above.

The expected result of our work is a universal system of data gathering with use of the developed modules of increase of accuracy ADC, with possibilities:

  • uses of cheaper element base (less exact ADC and DAC) at the expense of application of the developed module of correction of errors ADC;
  • increases of word length used ADC at the expense of application of the developed modules of the device of formation of absolute value of entrance signals ADC (provides increase in word length ADC at 1 category) and a source of basic pressure (provides increase of effective word length ADC on 1-3 categories because of decrease in level of noise of a source of basic pressure and increase of its temperature stability);
  • increases in speed ADC at the expense of application of the developed module of the device of a sample and storage (provides decrease in time of a sample and storage time increase);
  • decrease in power consumption in case of application of more simple ADC with the lowered power consumption

It is natural that the price of systems offered by us will be much more low, than at competitors.
