MANAGEMENT OF TRANSPORTATION AND TECHNOLOGICAL EQUIPMENT OF THE INDUSTRY BASED ON THE SMART SYSTEM
Abstract
High productivity and power of technological and transport mechanisms, large capacity and number of storage equipment, a variety of types of grain crops simultaneously processed at the elevator require the operator to make a lightning-fast decision, the optimal choice of grain transportation routes. One of the first control systems consisted of huge energy-intensive cabinets with starting equipment, allowing remote control of equipment, without the functions of elementary control of their operation. As storage volumes increased, these systems were supplemented with relay cabinets, whose task was to conduct interlocked control of an ever-increasing number of mechanisms, so that at least somehow it was possible to control such a complex. These relay cabinets had a low degree of reliability (contact elements), consumed a large amount of energy, and required the constant presence of large maintenance personnel. The era of microelectronics has come, which completely changed the idea of the capabilities of control systems. At first, it seemed very expensive and not a quick payback. But every year, the cost of automation equipment is decreasing, reliability has grown to high levels and this technique has come to the management systems of grain storages and elevators. Modern automation at the majority of Ukrainian elevators makes it possible to control technological processes. At the same time, many processes are regulated in a mode that requires a sufficiently high qualification of service personnel. The exchange of data on the operation of SMART-INDIVIDUAL equipment is carried out by logical controllers by polling sensors, generating control actions, monitoring equipment operating modes with display in the WEB-interface system. The SMART-INDIVIDUAL system has undeniable advantages over existing centralized control and management systems. SMART technology is inextricably linked with the dispatch control and data collection system - SCADA, designed to monitor and supervise a large number of remote objects or one geographically distributed object. The SMART-INDIVIDUAL system is equipped with a module with a regulation for monitoring parameters, equipment according to the passport characteristics. At the same time, the system maintains an archive and controls the timing of maintenance. The laboratory installation SMART-INDIVIDUAL includes technological and transport equipment, which is most used in the elevator industry: air filter ZEO-FCS, bucket elevator ZEO-BE, scraper chain conveyor ZEO-DC. On the basis of the SMART-INDIVIDUAL software and hardware complex at the Department of Technological Equipment for Grain Production of the Odessa National Academy of Food Technologies, students are trained in the new specialty "IT service of equipment".
