【Abstract】 According to the design conditions and parameters which client submits to Internet server, based on Internet, this system finishes the remote design of hydraulic system by the analysis and deducing method of Expert System. This technology belongs to the technical category about remote design of products. The paper takes good advantage of the strong analysis & deducing function of Expert System, developed computer technology and advantage application of Internet, so this design-system can liberate designer from the dull, heavy and traditional artificial-design work, and cut short the design period, as well as, can meet the development of products artificial design.The main achievements of this paper are listed as follows: 1. According to the design principle and standard of hydraulic system and the technical requirements of design-system, the design-system’s overall design plan is put forward;2. Advancing the three-tiers system architecture of design-system based on Web, and putting emphasis on the research of middle-tier of the three-tiers system architecture;3. Putting forward the system software architecture of design-system, which is based on COM/DCOM configuration. This software architecture improves software efficiency and net-safe of design-system, and strengthen the expansibility of systemsoftware;4. Putting forward an Expert System applying to design-system, perfecting the resolving of expert experiment and multi-results during hydraulic system design;5. Building the ASP dynamic pages net-site of design-system, and putting forward an interactive mechanism of hydraulic system design process;6. Adopting the reference and control technology of automation object, and realizing the reference, control and operation programming to AutoCAD 2000 in the IDE of Visual Basic 6.0;7. Putting forward a connecting lining plan to hydraulic system principle drawing, and this plan is based on the principle of robot’s track layout without colliding;8. Realizing the system software design and programming with the platform of Windows 2000 Server based on NT architecture and the object oriented development tool of Delphi 6.0;更多还原
