  1. Following the development trend of valve cad, according to the requirements of the chengdu chengfeng valve limited company and based on mdt, this article develops the 3d parametric valve design system. the main work and achievements are as follows : based on the 2d engineering drawing of the several different valves the company provided, the 3d parametric basic drawing - base is set up using mdt which is a 3d design platform, including all the parts drawings and the general assemblage drawings of the valve models ; in accordance with the common steps of the valve design, the parameter editors are designed to edit, import and export the valve parameters and are provided with the function of double synchronization on parameters displaying for convenience in use ; in order to meet demands of users and make the design more accurate, reliable and practical, the assistant formula calculators are developed, which can automatically do all types of structure calculation in the procedure of valve design, and export the calculation manual of valve design ; in order to make designers more rivalries, taking full advantage of internetmntranet technology, the virtual design center is developed, which integrate netmeeting, terminal service and super links, so that the designer can directl y use applications on remote server, communicate with other designers on intranet / internet, share software resources and realize long - distance cooperative design

    根據閥門cad發展趨勢，針對成都乘風閥門有限責任公司閥門設計現狀，本課題基於mdt三維設計平臺開發了閥門三維參數化設計系統，主要完成的工作和成果如下：根據公司提供的幾種不同結構閥門的二維工程圖紙，利用mdt三維設計平臺建立了三維參數化基本圖形庫，其中包括所有零部件和總裝配模型圖及二維工程圖；依照閥門設計的一般步驟設計了參數編輯器，用來對閥門尺寸參數進行編輯、輸入、輸出等，具有參數雙向同步顯示功能，使用十分靈活方便；根據用戶的需求，為了使設計達到精確、可靠、實用的要求，設計開發了輔助計算器，能自動完成閥門設計過程中所需的各種結構計算，並可以輸出閥門設計計算說明書；為了使設計人員更具有競爭力，本系統利用internet intranet技術設計開發了虛擬設計中心子模塊，虛擬設計中心集成了網路會議、終端服務、超級鏈接等功能，可以讓設計師直接使用服務器上的應用程序，與intranet internet上的其他設計專家進行交流、共享軟體資源，實現遠程協同設計。

  4. With the rapid development of wireless communication technology and computer technology ， people wish to get reliable data communication service any time and any where. traditional network can not supply communication service if the whole network need to move because the network devices are fixed by wires and can not move. so, ad hoc network comes. it can provide mobile data communication service compared with traditional network. ad hoc is a network with plat structure and all the nodes is equal. all the nodes need provide relay. but not all the nodes will provide relay and the performance of plat structure is poor in large scale. so the wireless mobile self - organized network adopts a two - level structure by referencing the cell mobile communication system. wmsn uses wireless routers to construct network. it can provide wireless access, relay services to users

    考慮到不是所有的站點都願意提供中繼服務及平面結構的局限性（在網路規模較大時性能會很差） ，本課題的無線移動自組織網路參考了蜂窩移動通信系統的特點，是一種具有兩級結構的網路。使用專門的無線設備? ? 「無線路由器」構成具有用戶無線接入、無線組網和路由功能的無線互連網路，為移動用戶提供無線接入、路由和中繼服務。 ieee802 . 11b可以提供很高的通信速率，可以提供很好的接入性能，並且支持ieee802 . 11b協議的設備正成普及的態勢，因此成為我們所選擇的鏈路層協議。
