Control Work

Currently, the means of measuring and converting information signals from equipment are widely used in industrial processing systems. For the most part, modern systems of mechanical processing of materials use mainly single-channel systems that work on information signals that identify the physical parameters of the technological process. Such a narrow specialization of monitoring one of the parameters usually reduces the reliability of the results obtained and, as a consequence, the reliability of the entire control system. The task of the work is to determine the possibilities of creating the foundations of the automated system on the basis of multi-channel information recording devices from processing equipment and possible approaches to the choice of criteria for the analysis of fluid information. As a result of the given analysis of a condition of branch and its modern transformations, the module of system for data collection on process (from a set of sensors) is offered for development, with a possibility of their further transformation on certain dependence, storage, transfer, and a possibility of signaling of certain events, for example, faults, for use in production automation systems and for equipment not included in the systems. At the same time, the multi-channel device of the sensor system provides opportunities to determine the full amount of information about the process. The basic modern means of control of work of technological processing CNC-equipment applied in the industry are investigated. The most perspective directions of development of multicriteria methods and automated control systems of technological equipment in the part of creation of complex sensors are determined. These sensory complexes register signals that are different in physical phenomena. The main approaches to the creation of control systems provide opportunities to build a theoretical basis given the logic of the system of obtaining specific information data in the automation of technological processes. Promising research at creating algorithms for such complex systems of quality control and diagnostics of technological processes can be aimed.

This work deals with the provision of underground, as one of the main modes of public transport, with automated control systems, in particular the provision of automated train management. It defines that the underground is one of the most progressive modes of transport, which is related to its environmental safety, comfort, and speed of movement, as this mode of transport does not intersect with other transport and pedestrian routes, which excludes traffic blocks. Underground is an important element of urbanized spaces, for it serves large passenger traffic. The article presents an algorithm for the creation of an automated control system for the underground train system. Based on this algorithm, a model of building an organizational and economic mechanism for automation of control systems has been developed. The diagram of organizational and technical implementation of the automated system of underground train management is presented. An economic analysis of the effectiveness of the application of the automated control system of underground trains was carried out. The recoupment on the acquisition and installation of automation systems is very high. The application of the automated system will increase the capacity of the underground by optimizing the traffic schedules, which will contribute to increasing its profitability. It is also useful to determine the reduction of electricity consumption due to the change in the dynamics of acceleration and braking systems, which is important, as the underground is a powerful enterprise. In the future, a promising direction is to streamline the coordination of train schedules and other modes of land public transport.

It is shown that quality assurance of block-modular electronic systems is achieved on the basis of reliability of control. It is necessary to provide control and diagnostics in full at all stages of the life cycle in the practice of developing and manufacturing programmable block-modular controllers. New results on the creation of the necessary means for automated control systems of serial-capable controllers are presented. Such systems can be used in preliminary and acceptance tests, as well as during adjustment in the production process. The algorithmic, software and hardware of the automated control system have been developed for functionally complete sets of modules (electronic panels). The development is performed for controllers in the tasks of the electric drive and can be used in other applications. The features of structural and circuit solutions and the layout of an automated control system are given.

Vessel control and automation systems that are not designed according to human-centered design (HCD) and coding principles risk being used inappropriately or incorrectly by vessel crews or pilots. As integrated bridge and automated control systems become more common, it becomes even more important to design human-machine interfaces (HMI) that allow for effective operation and control, while providing concise feedback to aid the operator in the decision-making process. This research examined the influence of HMI design issues on the safe and effective control of vessels 150 gross tonnage or greater through a review of Transportation Safety Board of Canada (TSB) investigated marine reportable occurrences that resulted in a published TSB report. Between 1998 and 2018, 31 (16%) of 192 such TSB investigations identified one or more HMI issue as a contributing or risk factor in a marine accident. Some of the HMI issues included: non-intuitive and complex navigation system design, non-standardized controls (steering, power, propulsion, abort mechanism) and poor system feedback. Despite the availability of marine guidance on Human Factors (HF) principles from well-reputed organizations like the major classification societies and the ISO (International Organization for Standardization), the current findings demonstrate that HCD methods are not always well-understood or consistently applied to the design and modernizations of vessels. A larger effort, such as a HF in design program, is required to promote the application and understanding of HCD principles in marine system design and operations to help improve safety while reducing the potential for use error.

The purpose of the scientific work is to build a scheme for the interaction of modules of an automated system for integrated protection of strategically important resources of an enterprise, in particular, a transportation industry enterprise. To ensure a high efficiency of the presented system, efficient allocation between the modules is necessary for the protection functions. Within the framework of this task, the article presents sets of functions for each security module. The outstanding feature of the work is the proposed scheme of optimal interaction of the modules of the automated system of integrated protection of strategically important resources of the enterprise. The article considers the mechanism of isolation of "affected" resources (and modules) of the main automated control systems of a transportation enterprise, consisting of the sequential execution of the functions of forming "affected zones and quarantine", the function of redirecting datastream. The paper presents a structural diagram of the interaction of modules of an automated system for integrated protection of strategically important enterprise resources, sets of functions for each module are formed, a scheme for ensuring isolation of "affected" resources is presented, the main difficulties of implementing an automated system are described, in particular, the features of its implementation at the transportation industry enterprise connected with the client-server architecture of the main AS, a number of additional organizational and technical measures for protecting strategically important enterprise resources are proposed.
