Open Universal Controller Model And Realization

With great improvement of computer science and network technique, idea of automatic control is widely applied to transportation, aerospace, industrial and agricultural production, building management, intelligent home, etc. However, traditional controller systems gain a variety of kinds of defects, such as incompatibility, high complexity, difficult to upgrade, unable to secondary development, technique behind hand and so on, which become a bottleneck for developing control system. As a multiple platform systems, Open Controller System is able to interact with other systems well and perform modular interface for customers as useful as possible. As a result, Open controller system is of practical significance to research. It is conducive to promote the optimization and applications and lower production cost. Moreover, it is a novel way for future development of control system.Open controller system pattern is shown as follows: Modern PLC - evolvement of traditional PLC; IPC - standards-based computer; Embedding Control System - inherits both advantages of modern PLC and IPC and becomes a new trend for development of control system. In this paper, we focus on the advantages of controller fusion between OGC and others. That is to say, according to the actual requirements, the whole cost will be reduced by compressing, extending and remedying the controller system. After that, the system owes high stability, occupies low resources and can not be disturbed by hardware or software beside the mark. Nevertheless, high integration of embedded microprocessors makes the chip obtains multi-function modules. The platform is improving better and better. Embedded real-time operating system can occupy low system resources and provide a strong guarantee for the upper application software development. As a result, transplanting Web Server and database on the embedded controllers for applications of upper functions, will carry out remote Web monitoring and analysis of large amounts of data processing functions.Control System works with Network, including long-distance control through the Internet, Intranet realize the management of enterprises, and network of the fieldwork use the plug-and-play technology will be a obvious trend in the future.
