摘      要
 
 作為20世紀(jì)新興的CAN總線技術(shù)，由于它所具有的眾多優(yōu)點(diǎn)決定了它具有廣闊的發(fā)展前景。目前這項(xiàng)技術(shù)已被應(yīng)用在汽車、醫(yī)療、電力、建筑和安檢等許多領(lǐng)域，而CAN總線技術(shù)在國內(nèi)造紙業(yè)的應(yīng)用還不多見。本文主要研究了CAN總線技術(shù)在造紙業(yè)中制漿濃度控制系統(tǒng)和多段烘缸蒸汽溫度控制系統(tǒng)的應(yīng)用。論文研究內(nèi)容對造紙行業(yè)的發(fā)展具有重要的實(shí)際意義。
 首先，論文對整個(gè)造紙行業(yè)的發(fā)展?fàn)顩r和發(fā)展前景做了介紹，并對自動(dòng)化系統(tǒng)在制漿造紙行業(yè)中的應(yīng)用狀況做了概述，此外，論述了CAN總線技術(shù)應(yīng)用于造紙行業(yè)的必要性。
 其次，論文從CAN總線的基本理論和基本概念入手，到CAN總線通信的核心技術(shù)和系統(tǒng)應(yīng)用，逐步深入地對CAN總線技術(shù)進(jìn)行了剖析和闡述,為論文后面的研究內(nèi)容提供理論基礎(chǔ)。
 再次，論文詳細(xì)記錄了課題研究中主要工作。采用80C196KC芯片，開發(fā)了制漿濃度控制模塊、多段烘缸蒸汽溫度控制模塊，完成了這兩個(gè)模塊硬件電路和軟件程序的設(shè)計(jì)框圖工作，并且實(shí)現(xiàn)了各模塊間基于CAN總線技術(shù)數(shù)據(jù)通信。
 最后，針對造紙生產(chǎn)過程的特點(diǎn)，提出了參數(shù)模糊自整定PID控制算法。
 本論文以現(xiàn)場總線CAN為基礎(chǔ)，研究它在造紙過程中紙漿濃度、多段烘缸蒸汽溫度測控中的應(yīng)用原理和實(shí)現(xiàn)方法，目的是改進(jìn)工業(yè)現(xiàn)場中測控的性能。該系統(tǒng)采用數(shù)字化的網(wǎng)絡(luò)通信模型，可以提高數(shù)據(jù)通信的可靠性和實(shí)時(shí)性。

Abstract
 The CAN bus is a new technology in 20th century. As a result of its many advantages, it has determined that it has broad prospects for development. At present, the technology has been used in automotive, medical, power, construction and security and many other fields, and the CAN bus technology application in the domestic paper industry is also rare. This paper studies the CAN bus technology in the pulp and paper industry in the concentration of control systems and multi-stage steam dryer temperature control system. Research papers on the development of paper industry has an important practical significance.     First of all, the thesis of the entire paper industry and the development prospects of the development is introduced, and automation systems in the pulp and paper industry has done an overview of the situation, in addition, on the CAN bus technology used in paper industry need.     Secondly, the papers from the CAN bus of the basic theory and basic concept to the core of CAN bus communication technology and systems applications, the gradual deepening of CAN bus technology for the analysis and sets out for the thesis behind the research to provide the theoretical basis .     Third, in paper detailed record topic research prime task. Uses the 80C196KC chip, has developed the pulping density control module, the multistage drier vapor temperature control module, has completed these two module hardware circuit and the software routine design diagram work, and has realized during various modules based on the CAN bus technology data communication.       Finally, in view of the papermaking production process's characteristic, proposed the parameter fuzzy self regulating decides the PID control algorithm.    In this paper, the CAN bus is based on the study of its paper-making process in the pulp concentration, multi-stage steam dryer temperature monitoring and control applications in the principle and method, aimed at improving the industrial scene in the performance of monitoring and control. The system uses a digital network communication model, can improve the reliability of data communications and real-time.
