Applied Research, Modern Network Technology In Cims

Computer network is the necessary support system of CLMSJ and the core problem of CLMS is the interconnection and communication of isomerous networks. In this paper, the important parts of contemporary network technology:: Fieldbus (including LonWorks~ CAN and so on)~ TCP/UDP/IP protocol set~ Integrated Services Digital Network (ISDN) and Asynchronous Transmission Mode (ATM)~ B/S Calculating Mode~ ASP technology~ WWW technology~ HTFP technology~ ADO technology and the new stage of CIMS Agile Manufactory, are analyzed and discussed. Fuithermore, a network stmcture of agile enterprise is brought forward, which includes two important partS: the interconnection sttucture of CLMS equipment networks and the MIS networks~. the interconnection structure of Intranets by Internet. The two corresponding core technology of the two important parts: the gateway between Fieldbus and TCP/IP Ethemet.~ remote database access system are developed. Moreover, they are successfully applied in the research projects 揌U-WSD Serial Multi-function Temperature and Humidity Control System? and ?B/S mode-based Supervision System of Telecom-Room?respectively, indicating that the stnicture which is put forward in this paper has super performances low cost% stated academic significance and biggish practice value.
