Beer Fermentation Control System of Computer Hardware Design and Implementation
ABSTRACT
The thesis mainly introduces the process of beer fermentation for the engineering background of the beer fermentation process automation and control strategy of the study aims to achieve the controlled use of advanced technology to upgrade traditional industries and skill levels a comprehensive practical significance. For beer fermentation process with large inertia, delay, non-linear, decentralized collection of the characteristics of distribution, the system uses a computer control system of distributed control system (DCS) Distributed Control. System can increase the degree of automation and integration of a variety of information, control of production processes. High reliability, high-performance, distributed control, centralized monitoring and management capabilities. The system uses the upper and lower control-bit microprocessor control program coordinated by the systems engineer and on-site control station component.Selected as a PC-PC, Siemens S7-300PLC as the under-bit machines, the use of PROFIBUS-DP bus implementation of the fermentation tank temperature and pressure control and management of on-site monitoring capabilities. Production Practice has proved that the anti-interference ability of the system running stable, user-friendly to meet the needs of a large-scale production can be applied in the beer industry.
