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.
