The Design And Implementation Of A Labview-based Wireless Teaching System

With the development of Electronic Information Technology, the whole society has entered an era of information explosion. Transmission style has developed from wire communication to wireless communication, information technology has become increasingly important in our daily life. And making full use of information network technology, introducing it into the traditional teaching to build a powerful, reasonable structure of the teaching system has increasingly been of concern. Our country has already made some progress on this issue, meanwhile some teaching institutions is using the network teaching. But most of the above based on wired connections, while the rest of wireless system, their function is simple, less powerful.Based on hereinbefore problems, in this paper, we designed and implemented a multifunctional wireless teaching system, in which voting system is the core, contains many functions like Check-in, Examination, Statistics, and Analysis. It can help promoting the teachers and students interact positively and improving the efficiency of teaching. LabView application here act as the upper computer software construct a good network teaching and learning environment.Specific studies as follows:We choose nRF24Le1 wireless module for wireless communication function, combined with LabView as host software, responsible for receiving, display and record the information, realize the interactive teaching between teachers and students. In addition, this paper analyzes the design of host software platform, in which the serial communication is achieved by VISA. LabSQL is applied to implement database access, complete a variety of data query function. Finally, produces executable programs, with Web Services application, make it easy for users to download.
