摘  要
 造纸工业是我国重要的基础产业，与国民经济发展和社会文明建设息息相关，在人们的日常生活中起着重要的作用。我省是造纸大省，有民丰、华丰等大型造纸企业，也有如富阳、龙游等地方上众多的中小企业。中小企业由于技术薄弱、资金短缺的问题，生产规模普遍较小，纸机的现代化水平不高，纸机的传动控制大多采用多点控制方式，生产效率低，社会效益差。目前大型造纸企业所采用由大型PLC组成的现场总线控制技术（FCS）的并不适合中小型企业的造纸系统。而近年来组态软件技术的发展为解决中小企业纸机所面临的问题提供了一个很好的途径。
 针对目前中小造纸企业现有的纸机设备工作效率低，同步性差，以及中小型企业普遍面临的资金短缺，技术薄弱等问题，本课题提出了构建基于组态软件的节能型纸机传动控制系统的方案。通过利用触摸屏、PLC、变频器和上位机来构建三级控制结构的纸机传动控制系统，并完成变频器的设置，触摸屏换面的设计和PLC的编程调试及系统各个组件之间的通讯等工作，构建完整的纸机传动控制系统，最终能通过触摸屏和上位机简单的人机界面完成对系统的传动部分进行的启停、调速等控制，并进行系统监控。该系统能有效的提高纸机系统运行的稳定性和工作效率，人机界面的操作简单易学，能轻易地对纸机系统进行精确地调速，系统变得更加容易监控，稳定的造纸设备可以提高造纸质量，并在一定程度上节约了能源的损耗。
 基于组态软件的纸机传动控制系统无论在工作的效率性，稳定性上还是在系统构建的经济性上都十分贴切目前中小企业的需求。因此，未来它在中小造纸企业会有比较大的发展空间。

Abstract
 Paper-making industry is an important basic industry, and the development of national economy and social civilization is closely related to people's everyday life in plays an important role. In papermaking province, there is abundant, huafeng people, such as large papermaking enterprises in fuyang, as many of the longyou of small and medium-sized enterprises. Due to the weakness of small and medium-sized enterprises, and the shortage of fund technology, production scale, the paper generally smaller modernization level is not high, the transmission control machine is used mostly multi-point control mode, the production efficiency is low, the social benefits. Currently adopted by large papermaking enterprises large PLC composed of fieldbus control technology (FCS) is not suitable for papermaking system of small and medium-sized enterprises. But in recent years, the development of technology configuration software solution for small and medium-sized enterprises are faced with the problem that paper provides a very good way.
 For small and medium-sized enterprise existing machine equipment, papermaking, low efficiency of small and medium-sized enterprises, and synchronized with the shortage of capital, technology, this weak proposed based on configuration software energy-saving machine drive control system scheme. By using the touch screen, PLC, frequency converter and PC to construct control structure of machine drive control system, and complete set of frequency converter, touch in the design and debug PLC programming and system components of the communication between each work, construct complete machine drive control system, and finally to touch and PC through simple interface to the transmission parts of the system, and the control and speed control system. This system can effectively improve the stability of the system with paper work efficiency of man-machine interface, easy operation, can easily to machine system accurately control system, easier to monitor, the stable quality of paper pulp equipments can improve in a certain extent, and save the energy consumption.
 Based on the machine configuration software in the transmission efficiency of work, the stability of the system is in the economy is very appropriate of small and medium-sized enterprises at present needs. Therefore, in the future, it will have small papermaking enterprises larger development space.
