Abstract
With the constant development of China''s economy, a high degree of information-based society, the new high-tech technology applied to all aspects of making intelligent has become a development trend.It is tended to be intelligent automation system equipment from the start. China in particular is based on the packaging, pharmaceuticals, textiles, food processing industries, such as the rapid development. Our Country will need more high-end line of control products, but also in the enterprise will be greater room for the development of major development direction. Application of the PLC-based control system technology for industrial production lines of control.
Using PLC control technology, advanced human-machine interface technology (touch-screen technology) to achieve automatic operation, Replace the previously used wire production lines Control System. This is not only designed to simplify and improve the reliability of the system, but the performance is superior to the traditional relay control system. With a touch-screen technology makes easy to operate, save space, implementation of the assembly line production and improve the degree of automation and production efficiency, reduce labor intensity. It was faced by the industry to solve the technical defects and improve the overall level of this industry.
