This article presents an analysis of the process of routing process lines in the elevator, which is carried out by an automated control system. The relevance of this topic is justified on the basis of the mismatch of elevator productivity to modern needs and volumes of grain products. As the organizational and functional structure of elevator complexes remains without significant changes, which directly affects the characteristics of the management of the technological process of transportation and as a consequence on the quality of grain products. And since the volumes and requirements will always only increase, the question arises in the increased efficiency of elevator processes under the same conditions, with possible changes that will result in modernization, optimization and improvement of the process itself without changing the technological layout of equipment. Therefore, the purpose of the study was to analyze the methods of organization and management of technological routes of transportation at the elevator complex, to determine opportunities to improve its productivity. During the study of the control process and technological routes of the elevator complex, the structural control scheme and the algorithm for laying the route of grain movement at the specified coordinates were analyzed. According to the found shortcomings, one of the directions of increase and improvement of technological process on the elevator was defined, which consists in improvement of control algorithms towards optimization of technological processes of the elevator on many criteria which should improve not only operational indicators, but also qualitative indicators of production. What is the problem in optimizing the modes and structural parameters of control of the electromechanical complex of the elevator, by improving existing and developing new methods, software and hardware means of operational intervention in the modes of electromechanical equipment of the elevator to improve energy saving and product quality.

Abstract This article combines the actual situation of the coal preparation plant and uses big data cloud technology to carry out detailed system requirements analysis and monitoring platform design. The entire design includes server framework design, database design, cloud service deployment and mobile client prototype design. According to the on-site working conditions of electromechanical equipment, the article uses ER model and 3NF method to abstract it and establishes a MySQL real-time database of equipment operating status. Finally, the ECS cloud server is used to complete the deployment, and the JSP technology is used to realize the display of the system’s man-machine interface, as well as remote monitoring services for equipment monitoring, information management, and user management. Practical application shows that the system can improve the comprehensive automation and information level of the enterprise, reduce the operating cost of the enterprise, and improve the production efficiency of the enterprise.

At present, modern spacecraft use high-precision equipment that is sensitive to influence impacts. In this regard, there is a need to create shock-free trigger devices for mechanisms for holding and releasing movable structural elements. These tasks determined the vector of development of electromechanical trigger devices that do not contain pyrotechnic devices in their design. Along with the new tasks, there are constant problems of rocket and space technology – the improvement of mass-dimensional characteristics. However, pyrotechnic elements force the use of massive housings and brackets for structures that can withstand a sharp increase in pressure and the impact of the executive parts. The use of universal pyropatrons does not always allow optimizing the design of the retention mechanism. Also, one of the disadvantages of working with pyrotechnic media is the increased risk of working. The paper presents the results of a study of the possibility of modernizing the design of trigger devices, improving their mechanical and electrical characteristics. The research was carried out using calculated and experimental methods, and experimental samples of trigger devices were manufactured and released. As a result of the work, an upgraded trigger device was developed, better electrical characteristics were achieved, power consumption was reduced (the response time was reduced), mass-dimensional characteristics were improved, and the number of structural parts was reduced.
