Communication method of process control system for aluminum plate and strip rolling technology

Abstract

The invention relates to a communication method of a process control system for an aluminum plate and strip rolling technology. Concurrent and associative access by name is supported by the communication method. Aiming at the concurrence problem and the problem that the type and the size of communication data are uncertain during the cross-process and cross-host communication process of the process control system of an aluminum rolling mill, the invention provides a solution. According to the communication method, the concurrence problem is efficiently solved by adopting a reactor server framework; the associative access is realized by combining a MAP container; a mode of random and concurrent processing access by communication variable name is finally realized; flexible and expanded associative communication is provided, and multi-process concurrent cross-host access and the random access by name of the communication data are supported, and therefore, the flexibility and the efficiency of data communication are greatly improved, the instant communication performance, the flexibility and the expansibility of the process control system of the aluminum rolling mill are effectively improved, and the expansion complexity of the system is reduced.

[0002] With the development of computer control technology, the level of automation and informatization of aluminum rolling mills is getting higher and higher, and the functional modules of the process control system are becoming more and more detailed. Each module under the middleware platform realizes cross-process and cross-host communication. , it is still necessary to realize the configuration of communication variables through header files and other forms. At the same time, due to the concurrent operation of multiple modules, the sharing and synchronization of communication traffic and many other complex considerations greatly limit the flexibility and scalability of the system, and the process Function expansion and improvement of control system

[0003] Traditional middleware communication method: the header file presets configuration communication variables, does not support associative access and dynamic expansion according to variable names, and is inconvenient in the application of multi-module concurrency and communication traffic expansion
