Research On Instrument Management And Measurement System Based On IVI Technology

At present,the instrument is used in many fields.In order to realize the overall management of the virtual instrument and the physical instrument,meet the demand of the instrument's exchange,improve the management efficiency and the efficiency of the instrument.This topic applies virtual instrument technology to instrument management,and constructs the unified management system of virtual instrument.Use this system to realize the instrument resources and local instrument drive configuration management and query and other basic functions.The main research contents of this paper are as follows:(1)Research and analysis of the principle and mechanism of IVI technology and VISA technology,combined with the use of part of the virtual instrument case,to determine the design and implementation of virtual instrument measurement and control system research ideas.(2)Deep analysis and Research on VISA and IVI technology.Through the analysis of the VISA software architecture and the underlying hardware communication,the principle of the instrument driver and the IVI engine to achieve the instrument swap.With the help of Python scripting language,realize access detection instrument system in the environment,and combined with the instrument interchangeability requirements for centralized user management instrument and instrument driver.(3)Based on IVI technology,this paper designs and implements the instrument management and measurement and control system,which mainly realizes the exchange of instruments and the measurement and control system.The system uses Python language to realize the development of user interface.At the same time,the implementation of the system function is introduced by using the Query function which is about information of the instrument interface and the IVI drive information as an example.In the realization of the instrument test panel,the PyQt4 is used as the exploitation environment to realize the display of the instrument information interface and the image display of the measurement results.
