In this paper we proposed a method for quantifying the total efficiency of programmable logic controllers from various manufacturers. The correct assessment makes it possible to select a programmable logic controller (PLC) as part of the implementation of the import substitution policy with a domestic product of devices from competing companies that have left the Russian market. The solution of the problem is carried out by the introduction of a linear rating scale for the selected characteristics of the PLC. Quantitative assessment of the qualitative characteristics of PLCs made it possible to obtain the value of the total efficiency for the PLCs considered in the work. Total efficiency is understood as a comprehensive assessment of the effectiveness of a programmable logic controller according to the selected characteristics. In this case, the characteristics may be of a different nature. We evaluated programmable logic controllers of four manufacturers: Siemens, Yokogawa, OWEN, ABAK. Seven characteristics of the PLC were selected for evaluation: mean time between failures, number of interfaces and plug-ins, power consumption, temperature range, number of protocols used, and response speed. The possibility of implementing the import substitution policy is considered. The assessment of the total efficiency confirmed the competitiveness of domestic PLCs in relation to foreign ones. The development of the presented evaluation method will make it possible to analyze the effectiveness of complex, large control systems made up of different types of equipment. The presented method can be used over time to obtain up-to-date information about the total efficiency.

Currently, crop production faces such problems as a decrease in soil quality, untimely detection of weeds, pests and diseases of cultivated crops, irrational use of fertilizers, pesticides, and water resources. This leads to an increase in production costs due to overspending of resources (fertilizers, pesticides, and water) and a shortage of crops due to inefficient decision-making in conditions of limited information, which causes the need for the introduction of innovative intellectual solutions in the cultivation of crops. Internet of Things (IoT) technologies have significant potential for a solution to the above problem. However, to date, these technologies have not been widely used, even in countries with a high level of information and communication technology development. The purpose is to identify the factors limiting the development of the Internet of Things in crop production and to determine ways to solve the identified problems. It is shown that the limiting factor in the development of the Internet of Things in crop production is the need to install a significant number of heterogeneous sensors, the lack of Internet and mobile communications in remote areas, as well as, in some cases, the problem of organizing effective data transfer from sensors to platforms for storage, processing, and analysis, or commands in the opposite direction to actuators. In crop production, an Internet of Things technology can be realized through the use of unmanned aerial vehicles as an IoT device and as communication technologies.

The article discusses the development of a software module for controlling electric drives as part of the ModBus industrial network, which was intended for modernize the automated control system of the production line section of the "Zarya" bakery plant. Frequency converters are used to change the speed of motors in the available control system, and the operator has to manually control each converter. The rotation speed of the motors is controlled by setting the frequency value, which is inconvenient for the operator. It is impossible to simultaneously change the operating speed of all production line equipment with this control method, which leads to mismatch in equipment operation. To solve this problem, a network is being built based on the ModBus protocol, based on available equipment. The article describes the main peculiarities of the ModBus protocol, developed method, that allows the operator to specify the required system run time instead of the frequency value for each motor, and developed software module, that implements the proposed method.

Digital twins of railway stations are necessary for planning work and taking the most effective management actions. An important factor is the compliance of the planned time costs with the actual ones. One of the tasks that are difficult to formalize at railway stations is the process of holding the rolling stock. This is due to the fact that the holding time depends on the human factor and the holding rolling stock. To create an automated station controlled by a digital twin, it is necessary to develop an automated holding system. One of the tasks in developing such a system is the problem of device location. This problem can be formulated as follows: it is necessary to place the minimum allowable number of holding devices in the controlled area in such a way that reliable holding is provided for any configuration of the rolling stock. As a tool for solving this problem, the most effective will be the use of methods of genetic algorithms. In this article, the authors consider the relevance of this study and the relevance of automating the holding of rolling stock.

The article discusses the problem of collisions with pedestrians at pedestrian crossings. An analysis of the conditions for the occurrence of accidents at pedestrian crossings was carried out, and the main factors influencing the risk of pedestrians getting into accidents were identified. One of the main reasons for such accidents is the “sudden” appearance of a pedestrian in front of the car. Other factors are also considered, such as poor lighting, dirt on the roads, insufficiently developed road infrastructure, etc. It has been established that high-quality street lighting helps reduce the number of accidents at pedestrian crossings. A formula has been proposed: “To prevent road accidents, you need to see and be seen.” The authors come to the conclusion that it is necessary to take measures to ensure safety at pedestrian crossings, such as installing traffic lights, improving road markings and lighting.
