摘要
 
 目前我國(guó)的造紙行業(yè)正處在發(fā)展階段，省內(nèi)的造紙企業(yè)還是以中小企業(yè)居多。由于資金薄弱，技術(shù)短缺，他們的中小型造紙機(jī)仍在采用多點(diǎn)式的控制方式進(jìn)行傳動(dòng)，其工作強(qiáng)度大，工作效率低，實(shí)時(shí)控制差，已經(jīng)越來越不能適應(yīng)企業(yè)的經(jīng)濟(jì)和社會(huì)效益。目前大型造紙企業(yè)所采用由大型PLC組成的現(xiàn)場(chǎng)總線控制技術(shù)的并不適合中小型企業(yè)的造紙系統(tǒng)。而近年來組態(tài)軟件技術(shù)的發(fā)展為解決中小企業(yè)紙機(jī)所面臨的問題提供了一個(gè)很好的途徑。
 針對(duì)目前中小造紙企業(yè)現(xiàn)有的紙機(jī)設(shè)備工作效率低，同步性差，以及中小型企業(yè)普遍面臨的資金短缺，技術(shù)薄弱等問題，本課題提出了構(gòu)建基于組態(tài)軟件的節(jié)能型紙機(jī)傳動(dòng)控制系統(tǒng)的方案。通過利用觸摸屏、PLC、變頻器和上位機(jī)來構(gòu)建三級(jí)控制結(jié)構(gòu)的紙機(jī)傳動(dòng)控制系統(tǒng)，并完成系統(tǒng)各個(gè)組件之間的接口連接，PLC的端口設(shè)計(jì)，變頻器的設(shè)置，組態(tài)軟件和PLC的編程和調(diào)試等工作，構(gòu)建完整的紙機(jī)傳動(dòng)控制系統(tǒng)，最終能通過觸摸屏和上位機(jī)簡(jiǎn)單的人機(jī)界面完成對(duì)系統(tǒng)的傳動(dòng)部分進(jìn)行的啟停、調(diào)速等控制，并進(jìn)行系統(tǒng)監(jiān)控。該系統(tǒng)能有效的提高紙機(jī)系統(tǒng)運(yùn)行的穩(wěn)定性和工作效率，人機(jī)界面的操作簡(jiǎn)單易學(xué)，能輕易地對(duì)紙機(jī)系統(tǒng)進(jìn)行精確地調(diào)速，系統(tǒng)變得更加容易監(jiān)控，穩(wěn)定的造紙?jiān)O(shè)備可以提高造紙質(zhì)量，并在一定程度上節(jié)約了能源的損耗。
 基于組態(tài)軟件的紙機(jī)傳動(dòng)系統(tǒng)無論在工作的效率性，穩(wěn)定性上還是在系統(tǒng)構(gòu)建的經(jīng)濟(jì)性上都十分貼切目前中小企業(yè)的需求。因此，未來它在中小造紙企業(yè)會(huì)有比較大的發(fā)展空間。

Abstract
 In nowadays , the  papermaking profession  in our country is occupying the development phase, in our province most of the papermaking enterprise are the small and medium-sized enterprise. Because shortage of capital, the weakness in technology, the middle and small scale paper mill was still using the multi-point control mode to carry on the transmission, its working strength is mass, the working efficiency is low, the real-time control difference, which is continually  could not adapt to the  enterprise's economy and the social efficiency.
 The paper machine equipment existing in the small papermaking enterprise，whoes working efficiency is low in view of present, the synchronism is inefficient  , as well as the Small and medium-sized enterprise faces generally fund shortage, technology weak and so on problems, this paper proposed the construction based on the configuration software's energy conservation paper engine drive control system's plan. Through using the touchscreen, PLC, the frequency changer and the superior machine constructs the third-level control structure the paper engine drive control system, and completes between the system each module's connection connection, the PLC port design, frequency changer's establishment, configuration work and so on software and PLC programming and debugging, constructs the complete paper engine drive control system, can finally completes through the touchscreen and the superior machine simple human-machine interface to system's transmission part carries on opens stops, controls and so on velocity modulation, and carries on the system monitoring. This system can effective enhance the paper machine systems operation the stability and the working efficiency, the human-machine interface simplicity of operator easy to study, can carry on easily to the paper machine system modulates velocity precisely, the system becomes easier to monitor, the stable papermaking equipment may improve the papermaking quality, and saved the energy loss to a certain extent.
 Paper engine drive system based on configuration software can meet the needs to the small and medium-sized enterprise in all about the machine system’s working  efficiency, stability and it’s economy. Therefore, there will be a big development opportunities in the future in the small papermaking enterprise.
