摘  要
 造紙工業是我國重要的基礎產業，與國民經濟發展和社會文明建設息息相關，在人們的日常生活中起著重要的作用。我省是造紙大省，有民豐、華豐等大型造紙企業，也有如富陽、龍游等地方上眾多的中小企業。中小企業由于技術薄弱、資金短缺的問題，生產規模普遍較小，紙機的現代化水平不高，紙機的傳動控制大多采用多點控制方式，生產效率低，社會效益差。目前大型造紙企業所采用由大型PLC組成的現場總線控制技術（FCS）的并不適合中小型企業的造紙系統。而近年來組態軟件技術的發展為解決中小企業紙機所面臨的問題提供了一個很好的途徑。
 針對目前中小造紙企業現有的紙機設備工作效率低，同步性差，以及中小型企業普遍面臨的資金短缺，技術薄弱等問題，本課題提出了構建基于組態軟件的節能型紙機傳動控制系統的方案。通過利用觸摸屏、PLC、變頻器和上位機來構建三級控制結構的紙機傳動控制系統，并完成變頻器的設置，觸摸屏換面的設計和PLC的編程調試及系統各個組件之間的通訊等工作，構建完整的紙機傳動控制系統，最終能通過觸摸屏和上位機簡單的人機界面完成對系統的傳動部分進行的啟停、調速等控制，并進行系統監控。該系統能有效的提高紙機系統運行的穩定性和工作效率，人機界面的操作簡單易學，能輕易地對紙機系統進行精確地調速，系統變得更加容易監控，穩定的造紙設備可以提高造紙質量，并在一定程度上節約了能源的損耗。
 基于組態軟件的紙機傳動控制系統無論在工作的效率性，穩定性上還是在系統構建的經濟性上都十分貼切目前中小企業的需求。因此，未來它在中小造紙企業會有比較大的發展空間。

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.
