4 . aiming at the problem of engineering drawing in technology information system, adopting distributed ( multi-users ), multi-types files management satisfied different queried types, edition management of data, share and security of data in the engineering (4)針對tis系統(tǒng)中圖檔管理的問題,采用了分布式(多用戶)、多類型的文件管理,滿足工程需要的不同的查詢方式,數(shù)據(jù)的版本管理問題,數(shù)據(jù)的共享和安全性問題。
technology information system ( tis ) assures the agility of enterprises and plays an important role in integrating and sharing of interior technology information, improving the efficiency in developing new product and shortening producing period and so on 技術信息系統(tǒng)(technologyinformationsystem,簡稱tis)對制造企業(yè)的信息集成與共享、提高產(chǎn)品的設計效率、保證設計與制造的有效性、縮短制造周期和提高快速響應市場能力等具有重要的作用。
according to actual requirement of tis for xinda pump factory, this paper puts forward a distributed structure and implementing scheme of technology information system based on three-layer mode, and explores some key technologies of software development . this paper's main conclusions are as follows : 1 . aiming at the problems of present tis and its trends, a structure of cad / capp / cam system is presented in this paper based on component technology and integrated pdm 本文以新達水泵廠的生產(chǎn)管理為背景,針對技術信息系統(tǒng)的實際需求,提出了建立基于三層結構的分布式技術信息系統(tǒng)的體系結構和具體的實施方案,探索了軟件系統(tǒng)開發(fā)的關鍵技術,其主要成果如下:(1)針對技術信息系統(tǒng)的發(fā)展趨勢及現(xiàn)有系統(tǒng)存在的問題,提出了基于組件技術以pdm為集成工具的cadcappcam集成的體系結構。
based on the analysis of situations of china, although a lot of high science & technology productions of agricultural university and colleges have been developed, information resources are scatted, and extension ways are insufficient too . the cooperation among universities and colleges is not enough . combining with the process and agricultural science & technology information system development and construction in china, a strategy of the network-information-based means in the form of " university's alliance " and in the model of distributed to integrated the resource of agricultural education of science and technology are put forward, i . e . to set up " an alliance of university agricultural science & technology and education network " information platform 本文從我國的國情出發(fā),全面分析了我國高等農(nóng)業(yè)院??萍汲晒芏?,但是資源分散,沒有形成合力,推廣力量薄弱、手段不足,高校之間缺乏緊密溝通與合作的現(xiàn)狀和問題,結合我國農(nóng)業(yè)科技信息系統(tǒng)發(fā)展建設歷程和現(xiàn)狀,提出了運用網(wǎng)絡信息化手段以“高校聯(lián)盟”的形式和分布式的方法集成高校農(nóng)業(yè)科技教育資源的對策,即建立“高校農(nóng)業(yè)科技與教育網(wǎng)絡聯(lián)盟”信息平臺,并通過系統(tǒng)分析、系統(tǒng)設計和系統(tǒng)實現(xiàn)的研究和工作,初步構建實現(xiàn)了分布式高校農(nóng)業(yè)科技資源集成系統(tǒng)。
