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.

The actualization of industrial development in the Far North poses many key tasks to the construction industry. Concreting is one of such tasks, the performance of which is much more difficult during construction at low temperatures. Based on this, it is necessary to design and develop innovative tools to optimize or rationalize work on construction sites in these conditions. The scientific significance of the presented article consists in an attempt to design a software solution that allows au-tomating the calculation of the parameters of the heating wire during winter con-creting. The practical value of the work lies in the possibility of using the presented materials as a basis for the practical implementation of this program.

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.

The article deals with the problem of inaccurate allocation of the boundaries of ore pieces after an explosion in a quarry in the photo. In this article, the possibility of using neural networks for segmentation of photographs was investigated, and training, testing and comparison of the pre-trained bases of neural networks were carried out. The family of pre-irradiated bases EfficientNet and SEResNet was tested on the FPN neural network. Neural networks were tested on the same number of learning epochs, and competitively on three, five, seven and ten learning epochs. Training for more than ten epochs was impractical, since almost all networks were undergoing retraining. According to the results of the test and comparison, the result was obtained that the FPN neural network on the pre-trained EfficientNetB2 bases after 7 epochs of training has a segmentation quality of 98.93% in three segmentation classes and 55.1% in the "ore pieces" class.

The object of the study is the method of evaluating the durability of the cutting tool, which evaluates the rationality of the periodicity of changing the cutting tool during turning on the basis of the indicator of vibration. To form a signal for the analysis the registration of vibroacoustic vibrations during the processing of parts by the device for measuring noise and vibration VShV-003-M2 takes place.

Prompt adjustment of the composition of the asphalt concrete mixture is key to achieving high quality asphalt concrete. To enable easy and rapid adjustment of the asphalt concrete mixture formulation, predicting the properties of asphalt concrete (Marshall stability) is critically important. There are many methods for predicting the properties of asphalt concrete, but the choice of one method or another is a very pressing problem. This article proposes two methods for forecasting Marshall stability: forecasting using a multiple linear regression model and forecasting using an autoregressive model. To evaluate the forecasting accuracy of models, we use two metrics: average absolute error (MAE) and average absolute percentage error (MAPE). The results of the study show that the autoregressive model exhibits better forecasting results, especially the second-order autoregressive model.
