Management of technological processes of transportation and drying of grain

Abstract

The article is devoted to solving management problems in the development of an automated workstation (AWS) of an operator-technologist for managing an elevator with a productivity of 280 tons per hour. In existing control systems, only grain transportation is provided (there are no systems with automatic drying of grain with high accuracy of humidity measurement), automatic formation of grain movement routes is not provided (for each route, it is necessary to draw up technical specifications and make changes to the control program of the system), and more precise control of grain flows (used automatic valves have only open / closed positions). A brief description of the proposed gate valve control algorithms, automatic construction of the grain drying route, filtering grain moisture readings and fragments of the operator’s workstation program (in the indusoft web studio environment) for managing the elevator complex is provided. The proposed solutions allow you to: reduce the emergency downtime of equipment by 20% and the total service time of the complex; weed out unfinished grain for baking in automatic mode for repeated drying; improve product quality due to automatic control of grain overheating; reduce product rejects by 3%, and also reduce the influence of the human factor on the process of transporting and drying grain.
