Design And Implementation Of Network Experiment Platform Of Modern Testing Technology Base

Experimental teaching is widely deemed as a powerful tool and indispensable link between theoretic science and practical engineering in teach of scientific subjects. However, the blooming demand of experiment itself, nowadays, is encountering a severe shortage of laboratory equipment, which have dramatically constrained teaching quality from further development. In this paper, a flexible and easily-accessible online experiment platform is proposed, upon which the experiment equipment in real world can be linked in a network and shared remotely. Hence, those conventional electronic experiment which could be exclusively conducted in modern testing technology laboratory can be groundbreakingly achieved online, rising to improved efficiency in equipment utilization, more comprehensive learner towards theoretical knowledge, and more experienced students towards practical operation.Proposed platform incorporates teaching management and remote experiment with the help of network technology, visual instrument technology and modern testing technology. Students can thus get access to equipment network via web browser and implement various experiment operations such as the online auto-testing, remote control, data obtaining as well as getting tutorial from tutor.In response to the above function, a web-tech based B/S three-layer architecture scheme is designed in this article, followed by detailed discussion about its physical structure and implement method. Briefly, this scheme consists of web server, web application server and SQL data base, among which the web application server(also known as platform network implement system) provides two operation modes i.e. real and visual mode respectively. The simulation mode, which is based on Labwindows/CVI software, acts as a supplement to the real mode when constrained time-space condition comes. Consequently, users can switch experiment mode flexibly. In the end, the effectiveness of proposed scheme is verified, and several potential functions which may be involved in the future work are proposed.
