Abstract


With the development of information technology in education , the rapid development of online teaching and popularization of network experiment teaching has always been one of the weak links , and thus build a break through the traditional limitations , regardless of time and geographical constraints of networked virtual laboratory is an urgent need to address the important issue. In this paper, hardware and software components from two aspects introduced virtual electronic laboratory design and implementation . Software is the key to the design . The system consists of virtual instruments , databases, applications of three parts. First , this paper introduces the basic principles of virtual instruments , the difference between them and traditional instruments were compared , outlining the virtual instrument development platform LabVIEW features. Then, the computer network technology and virtual instrument technology organically integrated in the existing hardware and software developed on the basis networked virtual laboratory system , to provide users with network-based, open- lab environment . The system uses C / S / B structure , build system based on J2EE technology platform , users simply have basic computer and network conditions , it is possible anytime, anywhere access virtual laboratory experiments . Then, the analysis of the characteristics of the SQL Server database , the database development process is given for various types of data structures , the table structure for in-depth discussion . In order to make the program has good adaptability and portability of applications and uses JDBC to establish the connection between SQL Server data . Virtual Web can not only save in the experimental laboratory education investment, more importantly, the institutions can improve the existing education system , improve the standard of teaching in schools and teaching quality , promote student learning autonomy , cultivate and improve students' practical ability and innovative ability , it will be built to improve the quality of students , and promote innovation and development of experimental teaching techniques and other aspects will play an important role.
