Mathematical and computer modelling. Series: Technical sciences| Резюме: | The trend of increasing the complexity and hardware of measurement systems (MSS) remains constant in connection with the massive use of computer technology in measurement processes. The excessive complexity of the newly created AZSV, the high cost of components and software, and the sufficiently low level of production quality do not allow us to rule out the possibility of errors, which cause a violation of the AZSV's performance as a whole, as well as a decrease in their productivity.
The term «reliability of the AZSV», similar to the term «reliability of the equipment» in the tasks of diagnostics of strain gauge equipment, means that «failures», in this case (it means the presence in the composition of the SV, in addition to purely hardware, as well as software), as a result of the appearance of errors, has a qualitatively different physical nature than purely AZ failures. This indicates the possibility of using certain terms and indicators of the reliability of technical means in the study of the quality of AZSV. In particular, this is justified by the need to solve the problem of resource (or cost) distribution between the AZ and the software (software) while ensuring the given reliability indicator of the JI.
Checking the correct functioning of AZ and software, which are part of the JI, is carried out at the stage of configuration and testing. As a rule, the main factor in the adjustment is the time spent on it. Therefore, in a number of models for assessing the reliability of JI, along with the necessary time of their operation in regular modes (the actual implementation of the measurement process), it is necessary to consider another time factor – the time of setting up AZ and PZ in relation to the use of these means as intended.
An effective way to determine the reliability of strain gauge systems, and especially at the design stage, is the use of mathematical modeling, the results of which are determined by the correctness of the models of measurement procedures based on it |
