| Foundation fildbus control system is the direction of control system development in recent years, so the study about fieldbus core technology and relative application can take an important part in improving our industry control level. We integrate theory study and practical application, design a measure and control flat roof, and do a lot of research on it, the main content is as follows:1) Aim at the development actuality of fieldbus control system, we study the methods and questions of integrating advanced control in fieldbus control system which can give a theory guide for fieldus application.2) According to studying protocol standard and key technique of foundation fieldbus, we design measure and control plat roof based on foundation fieldbus, and introduce the basic realization theory of hardware and software in this plat roof. the objects such as liquid level and pressure are very typical in industry. The design provides an example for industry process control system, and is benefit to the popularize and application of foundation fieldbus technique, and provides software and hardware help for the foundation fieldbus technique researchers.3) We apply OPC technology, complete fuzzy PID control arithmetic aimed at big delay-time temperature object in this plat roof, and offer a method of realizing advanced control in fieldbus control system. In practical industry process control system, referred to this implemention, other advanced control arithmetics can also realize. |
