Solution of problems of automation of elevator complex

The article is devoted to the solution of automation tasks in the development of the operator's workstation (AWP) for controlling the elevator with a capacity of 280 tons per hour as part of the work of LLC "Intelligent Automation Complexes". In the existing elevator complexes, only grain transportation is provided (there are no control systems with automatic grain drying with high accuracy of humidity measurement), automatic generation of grain transportation routes is not provided (for each route, a technical task is required and changes to the control program of the system are required). At the same time, more precise regulation of the flow of grain flows is required (the automatic latches used have only the "open / close" positions). The goal of elevator automation is: to reduce the time of equipment downturn by tracking the operating time of the equipment, the number of accidents and informing the operator about equipment that is susceptible to failure; reduction of the time for setting up and servicing the elevator; improvement of product quality; a decrease in the percentage of rejects, as well as a decrease in the influence of the human factor on the process. The paper provides a brief description of the proposed gate valve control algorithms, the auto-building of the grain drying route, the filtering of the grain moisture readings and the fragments of the operator's workstation program (in indusoft web studio) for controlling the elevator complex. The proposed solutions allow: to reduce the time of equipment downtime by 20% and the total service time of the complex; weed out the undried grain for ridding in automatic mode for repeated drying; to improve the quality of products through automatic control of grain overheating; to reduce the production waste by 3%, and also to reduce the influence of the human factor on the process of grain transportation and drying.
