Open-Science Space Issue: Calibration of Measuring Channels of Non-Dismantling Cyber-Physical Systems

Abstract

The analysis of the concept of Open-Science Space is carried out. The existence of ways to achieve reproducibility and traceability of research results performed by a group of worldwide situated Cyber-physical system operators/supervisors is shown. Ways to ensure the efficient operation of Cyber-physical systems as complex technological nondemountable objects with high requirements for metrological characteristics have been studied. To develop the scattered cyberphysical systems, the portable stable-in-time code-controlled measures of physical quantities have been studied. They have to be metrologically confirmed in the laboratory before the delivery to the site of the measuring subsystem for its calibration.

“…In addition, the implementation of such methods is associated with a significant increase in cost, which reduces their competitiveness. However, even when using the most accurate and stable components, the performance of technical products is subject to temporal degradation and exposure to variable parameters of operating conditions [6][7][8]. Therefore, the application of structural-algorithmic (self-testing, self-diagnosis) or organizational methods (periodic metrological control) [9][10][11][12] is in this case a technical compromise.…”

“…The following operations are performed periodically and consecutively over time. The output of the reference voltage source (RVS) is connected to the input of the code-controlled resistive divider by locking key S5 and turning off key S6, and then the RVS output is turned off and the input of this divider is shortened by opening key S5 and closing key S6 [6,7]. ACE is formed due to the ADC bias voltage and the flow through the resistors of the divider of the input currents of the ADC and reverse leakage currents and key drains.…”

“…For other devices with standardized metrological characteristics, it is almost impossible to confirm the metrological suitability of measuring channels in the classical way due to their significant number. The process of metrological confirmation is associated with the verification of such equipment in special laboratories, accompanied by the dismantling and installation of measuring equipment at the place of operation [6,7].…”

“…ADC is the main link between the input of information about the parameters of the "physical" world and the "digital world" in many technical devices of cyber-physical systems, Internet of Things and other multi-channel measuring systems, even household portable devices. However, the spatial scattering of such systems for the transformation of measurement information makes it very difficult to ensure the practical unity of measurements [6][7][8]. Due to a set of unique technical and consumer characteristics, modern ADCs are used as discrete or embedded components in a variety of areas such as Aerospace and Defense, Automotive, Communications, Energy, Healthcare, Industrial Automation Technology, Instrumentation & Measurement, Smart Buildings [7][8][9][10][11][12].…”

“…Due to a set of unique technical and consumer characteristics, modern ADCs are used as discrete or embedded components in a variety of areas such as Aerospace and Defense, Automotive, Communications, Energy, Healthcare, Industrial Automation Technology, Instrumentation & Measurement, Smart Buildings [7][8][9][10][11][12]. Therefore, given the massive use of ADCs it is necessary to ensure the possibility of operational metrological control of their parameters, especially at their place of operation [6][7][8][9].…”
