Abstract
The digital twins technology delivers a new degree of freedom into system implementation and maintenance practice. Using this approach, a technological system can be efficiently modeled and simulated. Furthermore, such a twin offline system can be efficiently used to investigate real system issues and improvement opportunities, e.g., improvement of the existing control system or development of a new one. This work describes the development of a control system using the digital twins methodology for a gas system delivering a specific mixture of gases to the time-of-flight (ToF) multipurpose detector (MPD) used during high-energy physics experiments in the Joint Institute for Nuclear Research (Dubna, Russia). The gas system digital twin was built using a test stand and further extended into target full-scale installation planned to be built in the near future. Therefore, conducted simulations are used to validate the existing system and to allow validation of the planned new system. Moreover, the gas system digital twin enables testing of new control opportunities, improving the operation of the target gas system.
Highlights
Academic Editor: Chris BlackmanDigital twins technology is a relatively new notion [1,2]
According to the digital twin approach, a replica of some physical object is developed and it can be seen as a wide-use simulator [10], as a predictive model, and a tool that enables equipment prognostic and diagnostics [11] by monitoring and remotely detecting, in real time, anomalies that may result from equipment failures
The objective of this work is to describe the development of a control system for a gas system (GS) delivering a specific mixture of gases to the time-of-flight (ToF) Multi Purpose Detector (MPD) used during the high-energy physics experiments in the Joint Institute for Nuclear Research (JINR) [36]; it is located in Dubna, Russia [36]
Summary
Digital twins technology is a relatively new notion [1,2]. It brings well-known modeling and simulation technologies to a new level [3]. The objective of this work is to describe the development of a control system for a gas system (GS) delivering a specific mixture of gases to the time-of-flight (ToF) Multi Purpose Detector (MPD) used during the high-energy physics experiments in the Joint Institute for Nuclear Research (JINR) [36]; it is located in Dubna, Russia [36]. A full-scale ToF detector is still under construction and does not exist in full scale Once accomplished, it must be equipped with an efficiently working gas system.
