Research And Development Of Strategy Configuration Software Package For Distributed Intelligent System Based On IEC61131-3

With the fast development of network technology and the burgeon of filedbus technology, manufactures home and abroad come up with their own products. A new upper-level control strategy configuration is always come with a new control system. System control strategy configuration software which is running in upper-level computer is a key component in the whole system. There are many problems and defects in configuration software developed home and abroad at present. On the other side, WorldFIP fieldbus technology has its own inborn advantage and is used worldwide. the Development of distributed control system based on WorldFIP is very practically meaningful. Therefore, development of control strategy configuration software for distributed control system based on WorldFIP technology and IEC standard by which a wholly distributed system is implemented can provide concrete guide for the further development of configuration software in the line and play a leading role in self-research and self-development in our country. So it is very meaningful practically and theoretically. The dissertation is based on the whole design and development procedure. The functions ,components, structure and the design and development of the whole software system and its every component is introduced and expounded in detail based on the analysis and comparison of the status and problems of the strategy configuration software developed home and abroad. The train of thought, theorem and methods used in design and implementation for the problem-solving and improvement for scheme of the system. The feature and creation in the system is introduced emphatically. The main contents of the dissertation are : (1) Firstly, the progress of burgeon and development of strategy configuration software for several kinds of distributed intelligent system is looked back in several angles. The reason for the burgeon and development of the strategy configuration software for distributed intelligent system are analyzed systematically, historically and practically. The great significance of developing distributed intelligent system based on fieldbus technology and its strategy configuration software with full intellectual property is pointed out after the background is analyzed and summarized theoretically and practically. The great significance of the subject is further demonstrated after the current status and problems existing in strategy configuration software for distributed control system home and abroad and the application, research and development of distributed intelligent system base on WorldFIP are analyzed and compared. (2) Contents related to IEC61131-3 is expounded and introduced. (3) The strategy configuration software FIPCONF with full intellectual property for WorldFIP fieldbus intelligent system based on IEC61131-3 standard are developed in home for the first time which is based on the compiled media code technology and functionally perfect. The function, services and the selection for the user's programming language is introduced concisely. The train of thought, scheme and implementations of the key component of FIPCONF system are expounded in detail. The innovation in FIPCONF is expounded and demonstrated all-round and in detail in concept ,function and meaning based on the analysis for the problem and limitations existing in the configuration at present by method of comparison. the concept of scheme for the transplant of field device oriented instruction code based pm compiled media code technology is advanced in home for the first time. The concept of "user configuration's independence of hardware" is advanced and the scheme based on the concept is designed and implemented; the concept of two operation mode for configuration project is advanced and the scheme based on it is designed and implemented; the concept of "separation of strategy logic configuration from physical configuration" is advanced and its design and implementation scheme is provied; the concept of "embedding of network communication function into FCS configuration softwar...
