subject: Automatic Control System In Liquor Production - Control Systems - Electrical Industry [print this page] White wine is a traditional industry, is one of the world's six distilled liquor. As market competition intensifies, the technical requirements of the liquor industry has further improved, this is bound to speed up the liquor industry in the shuffle, so that those without economic strength, technology level is relatively backward, not high corporate brand reputation has been eliminated. In this grim situation, liquor companies only from internal potential to reduce production costs, improve product quality and production, and promote the improvement of overall efficiency in order to make business by leaps and bounds.
Nowadays, many liquor companies regard the technological innovation to enhance competitiveness as a business fundamental way, giving this traditional industry has injected new vigor and vitality. But Other Industries, the liquor industry's technological innovation capability is relatively weak, therefore, speed up technological development is the industry's top priority.
Back in 1996, Hubei Rice Flower Wine Company Limited and the China Shipbuilding Industry Corporation will be No. 710 Research Institute Cooperation Developed the "Liquor forming Distributed Control System", the successful promotion of the rice flower development. But with the continued expansion of production scale, the system can not meet the production needs. To achieve device control, process control, production control between the "integrated control" and promote the production to "high quality, safe, low consumption, can be recycled" in the direction of development and realize the whole process of liquor production (stock tanks, blending , metering, filtration, transport, filling) the monitoring and control, rice flower and the 710 Institute, jointly developed the "new generation" Rice Flower white students (Source: China wine newsletter?

1 System Components Control system consists of data servers, engineer station, blending operation station, filter operation stations, transmission stations and field operations I / O stations and other components.
1.1 data server running on 32-bit windowsNT/windows2000 platform can be attached local area network and wide area networks, as system operator stations, engineering stations to provide data access services and to provide a database for online queries.
1.2 engineer station windowsNT/windows2000 running 32-bit platform, enabling the system configuration and monitoring functions.
1.3 blending operation station, the Profibus bus and station engineers and other sites connected by programming the controller to control the corresponding electric ball valves, electromagnetic flowmeters, blending pumps, pressure transmitter complete the blending process.
1.4 filter operating station, principle ibid.
1.5 transport operator station, principle ibid.
Field I / O points through Profibus bus and engineer station and other sites to connect, according to the operation of the control station or engineer station instructions, operate to control the corresponding device, and to engineer station with equipment status signals and performance data.
