Research On Remote Training And Assessment System Of Optical Cable Based On Virtual Instrument Technology

With the development of China’s economy and science and technology,more and more precise and intelligent special instruments and equipment are put into use in scientific research and production.Among them,some expensive instruments,such as ANT-20,are inconvenient to move and expensive,and the stations are scattered.How to learn and train such instruments has become a big problem.With the rapid development of network and computer technology,virtual training,a new training method,has developed rapidly.Combining virtual instrument-based training and assessment with remote control of real instruments,an efficient and object-oriented training and assessment system can effectively solve the problem of traditional training affected by time,space and experimental equipment,and realize fast,economical and efficient training.This paper analyzes and designs the ANT-20 network analyzer and develops a training and assessment platform based on C/S mode.Users can master the method of using ANT-20 instrument through learning and training and assessment on software,and realize remote operation.In this paper,the historical development and current situation of virtual training at home and abroad are integrated and the demand is analyzed.The whole system is divided into login management module,training assessment module and remote control module.The login management module is the key of the whole system.Users can conduct a series of training and assessment operations after logging in and entering the system.Administrators can edit user information and instrument information after entering the system.Training appraisal module to simulate the ANT-20 meter/defect analysis,anomaly/defects occur,jitter,and testing,cost,cost analysis,PDH/analysis,performance analysis,and analysis and a total of nine function pointer and pointer happen multimeter,oscilloscope and signal generator and the function of error instrument,beginners can on the platform for training and assessment;The remote control module realizes the information exchange between the client and the server through TCP/IP,connects the server and ANT-20 through NI’s GPIB board card,and enables the user to control Ant-20 through VISA.The system has strong flexibility,adaptability and pertinence,especially in the situation where the trainers’ operation level is quite different and their professional knowledge is not strong.Through testing and verification,the system runs stably and modularized,which makes the system has strong scalability and application value.
