FEATURES OF ON-SITE CALIBRATION OF MEASUREMENT CHANNELS IN DISTRIBUTED SYSTEMS

This paper substantiates an approach to performing calibration procedures for measurement channels on-site in distributed cyber-physical systems. A conceptual model of a local metrological supervision system is proposed, which provides calibration considering real operating conditions. Special attention is paid to the use of code-controlled measures to generate reference signals and a centralized module for remote control, data processing, and storage. An algorithm has been developed to remotely transmit control signals to code-controlled measures, receive the output intermediate conversion codes, calculate, and store the calibration coefficients in the calibrated measurement channel. Theoretical analysis confirms the possibility of achieving the required measurement accuracy and significantly reducing time and resource costs compared to traditional methods.
