This paper briefly introduces the contents and characteristics of the software reuse technology and industrial control software. The development of the software reuse technology in industrial control software area is discussed emphatically. Then the article brings forward a kind of thought that establishes standard element class library and develops the application program frame adapts to industrial control area. Namely, they are the establishment of the reuse of standard element class library based on the level of class library, the design of the reuse of the program frame based on the level of design, the amelioration of the reuse of the designing method based on the level of analysis. This thought improves on design method of industrial control software and is applied in the real-time monitoring system for the high-press water pump station. 相似文献

Electronic business is a model of automation business activities, so the concept of field bus control system that is the latest control technology in automation control domain could be transplanted into electronic business structure to optimize the performance of the electronic business. The author studied the model which had centralize distributed structure and built under the concept of FCS in the environment of electronic business. By analyzing the performance of shops online, authority center and logistics distribution center that have the centralize distributed structure, the conclusions could be drawn that the centralize distributed structure model of electronic business has the advantages of high reliability, rapid response, high expandability, easy to rebuild and high system efficiency that FCS has. 相似文献

The development of E commerce is booming. Now the management of some domain is converting from tradition to E commerce, this needs the application and integration of the latest information technologies for the maximum usage and share of network information resources. As a modeling language, Unified Modeling Language (UML) is well defined, easy to specify, powerful in function and applied widely. Business model concentrates on the business around the system, not every project requires business model. However, there are many situations where business modeling adds a great deal of value. Establishing system business model is the primary task when people make use of UML to establish E commerce system model and develop software system. By E commerce system the authors expound the use case, and propose how to use correct method to establishing E commerce system business model. 相似文献

CNC system is gradually developing toward flexible, component modular and re-configurable of open CNC system's structure. It's beginning a research direction in open CNC system with the software reuse and re-configurable technology. Based on the expound of concepts and characteristics of component technology, open CNC system's characteristics are analyzed based on COM and open CNC system is divided into several components. With the characteristics of binary language irrelevant, thread transparent, re-configurable and normative interface of COM technology, open CNC system's interpolate-compensation component in interpolate-compensation component achieved, interface designed and object created are researched. Better effects are achieved by connecting the interpolate-compensation component with the other CNC components. At the same time, the CNC component's real-time control problem is analyzed. 相似文献
