Design And Implementation Of Test System Based On Mobile Platform

Due to the continuous development of information experiment in colleges and universities,it is imperative to replace the traditional experimental methods influenced by time,space and experimental equipment with virtual simulation experiments.Under this background,this paper proposes simulation experiment software based on mobile platform test system,which can solve the problems of shortage of space and equipment faced by experimental teaching in colleges and universities.The main content of the research in this paper is the design and implementation of a test system based on a mobile platform.In this article,the mobile platform uses a smart phone with Android system to complete the software functions on the mobile terminal.The main work includes three parts: reloadable module,remote control experiment and virtual simulation experiment.First,the overall design of the software system is given based on the analysis of the requirements of the test system,and then the design and implementation of each functional module are introduced in detail.The specific work content of the thesis mainly includes the following contents:(1)Reloadable modules.This module is proposed to expand the interface of different models or manufacturers of the same type of instrument.The overload is that the instrument interface has common functional features,and the unique functional features of the instrument interface are updated to complete the loading of different interfaces of the same type of instrument.(2)Remote control experiment.The module uses socket communication based on TCP protocol combined with Wi-Fi transmission to complete the program control function of the mobile phone software and physical instruments.Mainly realize the functions of data communication,data processing,and waveform display module.Use the functional module to complete the remote control experiment: instrument interface remote control experiment,SCPI instruction learning experiment,pulse parameter measurement experiment.(3)Virtual simulation experiment.It mainly includes the virtual simulation experiment management system and the realization of the simulation experiment function,so that the simulation experiment system can be set up in the mobile phone software without relying on the physical instrument.The virtual simulation experiment includes the virtual simulation function generator function and SCPI instruction learning experiment.The virtual simulation function generator can display the waveform type,set parameters,parse the instructions,and use the virtual simulation function generator to dialogue with the SCPI instructions on the simulation experiment management system.The box completes the simulation program control experiment.(4)Implementation of the software interface.The work content mentioned in the first three points is inseparable from the interface design.According to the specific functional requirements of each functional module,the software interface that meets different measurement functions needs to be implemented in combination with the layout,buttons,sliders,pop-up windows and other components in Android.This paper completes the software functions of the mobile platform test system,and performs functional tests between the mobile phone and the physical instruments.Each functional module can work correctly and effectively,confirming the practicality of the test system software.
