Research And Application Of Data Monitoring And Control System Based On B/S

Because of rapid devoloping of Internet,the computer network application system on customary structure is replaced with three-layer structure application system based on Browser/Server(B/S).Applyiny this mode to remake customary or bulid new data monitoring and control system,which has broad-basee development prospect and profound meaning.Due to traditional DMCS's(data monitoring and control system) limiting,a lot of field information is only acquainted by field operator,but isn't possessed by senior manager. Considering the requirement of modern management and market's application,this thesis presents the research and application of DMCS based on B/S by intrducing the B/S for DMC .The hardware and network architecture model,application and exploiting environment,functional constructions of server and browser and software design techniques of DMCS based on B/S are proposed and discussed in this thesis.In this thesis,studies have been carried out as follows:The research and developing status of DMCS based on B/S is reviewed systematically and the thought of DMCS baed on B/S is also proposed.Along with the analysis of the necessity and basic characteristics of DCMS based on B/S and considering various application scope ,from two sides of LAN and WAN the architecture model of DCMS based on B/S is built,functional construction and design are described,and the DCMS based on B/S is designed as well.The application and developing environment is studies,considering various application and exploiting scope,the right environment of application and developing is selected based on three-layer structure of B/S.The architecture model of DCMS web server and database server is studied,the software structure is described from the perspective of software engineering.The server software system is well completed by the new software design means such as ASP,ADO,ActiveX etc.as well.Using IE as browser,the safety mechanism of client software is founded by thenew software exploiting tools.At last,the correctness about the system structure,application and exploiting environment,research technique of software are proved.
