Assistant Experiments System Of Electronic Circuit Based On Three Layer C/S Mode

There are many disadvantages in traditional electronic circuit experiments, such as baldness of content and form, complexity in experiments operation and so on. So the improvement of traditional electronic circuit experiments should be carried out urgently. In modern times, network education and long-distance education are rising and developing rapidly, because of abundance, communion and real time of their resources. The developing techniques of software and network gives good path to the improvement of traditional electronic circuit experiments.Assistant experiments system of electronic circuit based on three-layer C/S mode uses advanced three-layer Client/Server system, with the characteristic of abundant content, communion and real time system, making assistant experiments function come true. This system mainly uses network communications function of Visual C++ and network data database of SQL Server. This thesis introduces origin, significance and research situation of topic firstly, and then introduces concept and configuration of three-layer C/S mode. The thesis emphasizes on network communications function of Visual C++ and discusses particularly key technique and application of WinSock. Then it compares SQL Server with other databases technique and introduces designed data table for this system and discusses particularly key technique and application of ADO. In the end, this thesis introduces idiographic design of system, describing design idea and idiographic function of client and server respectively. This system has already been finished and can make use of. Assistant experiments system of electronic circuit based on three-layer C/S mode is a huge improvement of traditional electronic circuit experiments, and this design will have large developing space also.
