Digital transformation of industrial machinery repair and maintenance to build an industrial metaverse

Article preview

Industrial metaverse is a new direction for development of industrial enterprises. Nowadays the process of full understanding term “industrial metaverse”, its conception, its effectiveness for enterprises is not actualy completed. The methodology, tools, and methods for building an industrial metaverse have not been clearly defined. Therefore, it is advisable to experimentally implement a part of the metaverse on one or several processes with future scaling to other processes. The process of industrial machinery repair and maintenance is proposed as an experimental zone for implementing the industrial metaverse. This process is well suited as an experimental zone. Launching the industrial metaverse concept on it will solve a number of problems, such as the diversity of equipment with unique diagnostic and repair methods, human errors made during repair work, etc. This article presents the concept of building and the architecture of industrial metaverse. A general description of the physical, cyber-physical, and social spaces and the interaction layer between them is provided, without any details of qualitative and quantitative indicators. The avatar of a service engineer is highlighted as one of the elements of the cyber-physical space. The process of creating an avatar of a cyber-physical service engineer is considered: a description of the main functionality is provided, it is shown that a combined system of wearable devices – a glove and a video camera integrated into glasses, a vest, a helmet, or represented by an independent device – is sufficient for its creation. Laboratory experiments were conducted, where the created avatar was tested to determine the task of servicing a centrifugal pump. The results of processing 518 experimental datasets of 10 points, each of which belongs to one of six classes corresponding to a specific technological operation during servicing of a centrifugal pump are shown. Three types of models were obtained (accuracy on training data 0.99; 1.0; 1.0, accuracy on test data 0.625; 0.7; 1.0). It has been shown that achieving 1.0 accuracy on training and test data requires first identifying features representing frequency and temporal characteristics obtained through time series processing. The obtained results allow to make conclusions about the readiness of these technologies for industrial implementation.

System of automatic control of damage of slurry lines

Article preview

In the degree we can see the system of automatic control of breaking of trunk pipeline of mineral resources, which based on explosion effects of acoustic emission and developing on based of mathematic model get around impulse of pressure in trunk pipeline system. You can see the main advantages this method. It’s important thuf explosion of this method can help us to spend less time on making of diagnostic works and economize money, spending of this industry.

Microprocessor control system for an integrated conveyor line

Article preview

The problems of automated control of continuous rock mass transportation systems based on the use of microprocessor technology are considered. The main tasks and technical solutions for automation of automated control systems (ACS) are presented. The structure of such systems is described, the issues of reliability and prospects of using ACS in controlling conveyor lines are investigated, advantages and disadvantages of existing conveyor control systems are indicated. It is offered to increase control efficiency by means of creation of the distributed ACS of the conveyor line, consisting of several microcontrollers (MC) in ACS, controlling each of the industrial mechanism, but subordinated to the main MC, the functional diagram of one of such systems and the algorithm of its functioning is resulted.
