| Abstract:Most of the traditional paper machines are driven divisionally by multi-motor, with low intellectual faculties, poor real-time control, low precision and efficiency. In order to overcome these shortcomings, the paper put forward a control system based on PLC and touch screen. The PLC is the core of the system, which stores, computes and transmits the real-time data collected from paper machine with the sensor to control the machine running. At the same time to communicate with the touch screen, the machine operating data is displayed in the form of a dynamic figure, and the preset parameters on the touch screen were accepted to control the executive component to realize “man-machine dialogue” function between the operators and the paper machine. The simulation commission proves, the system is simple and high intelligence, its application improves product quality and production efficiency, and to some extent, reduces energy loss. |
