Research And Development On Design System For Construction Metal Structure Products In Network Environment

Construction mental structure products are the products which include doors and windows, curtain walls, skylights, etc. The enterprises of Construction metal structure design or manufacture construction mental structure products for the industry of construction. As China being one member of the WTO, the state economy develops quickly and the industry of construction appears flourishing. However, it is usual that the enterprise is too small in the construction mental structure area. And during the course of construction mental structure products' designing and manufacturing, there're some widespread problems such as long design cycle, high error rate, difficult to total the material, large amounts of information, and time after time rehandling, etc. At the same time, product design is dispersive and personal, and difficult to cooperate with each other in enterprise, difficult to collect, classify and share the information. So considering the phenomena of the industry of construction mental structure and the existing problem, it is significant to develop the system of design for construction mental structure products.At first, this paper explains the characters of the enterprises and their products of construction mental structure, and analyses the design flow of construction mental structure and the problems existed and the requirement during the products design. On the base of it, the paper offers the scheme by which the system is developed in network environment of an enterprise. This paper offers the architecture and functions of the system and also offers the operation model of the product design in network.Then on the base of these, this paper studies the key technologies applied in it. Firstly, it focuses on the Socket technology, and proposes the method of n-tier by Socket to integrate data of the system. Secondly, this paper proposes a regulation which is composed by four elements to control rights and offers the plan of rights management on the base of COM/DCOM technology. Thirdly, this paper analyses the thought of prototype model and proposes the product design technology realized by it.At last, associated with the work, aimed at the problem existed in product design, considered the real situation of the example factory, the system is designed and developed. And the applying instance is demonstrated. The product design system is developed in the environment of network on the base of the 863/CIMS object product--"the system of Computer Aided Design and Product Management forconstruction mental structure products". The system has been applied in the example factory and has got good effect.
