摘要:设计了一种基于PLC和触摸屏技术的纸机多段速度控制系统。该系统以PLC为核心,对传感器采集的纸机实时数据进行存储、计算及传输,控制纸机的运行状态。同时与触摸屏进行通信,将纸机运行数据以动态图的形式显示,并接受触摸屏给定的工艺参数来控制执行元件,实现了操作人员与纸机的人机对话功能。通过模拟调试,该系统操作简单,智能化程度高,提高了产品质量及生产效率,并在一定程度上降低了能耗。
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.
