Design And Implementation Of Remote Client For Traveling Wave Tube Automatic Test System

The traveling wave tube belongs to the vacuum electronic device.With the deepening of the research on the traveling wave tube,the application scope of the traveling wave tube is increasing year by year.With the development of information technology,the requirements of the measurement method More standardization and specialization.The traditional method of measuring the parameters of traveling wave tube is time-consuming and laborious,which is affected by factors such as time,space and equipment,and the measurement efficiency and precision are restricted greatly and can not meet the needs of today's society.In order to save manpower and material resources,away from some dangerous measurement environment,and improve the measurement efficiency and accuracy,with the help of computer software technology,to create a remote test system based on traveling wave tube client has important practical significance.In view of the above problems,this paper discusses the current research situation of traveling wave tube parameter measurement method at home and abroad,analyzes the definition and measurement principle of the input and output power,gain linearity and harmonic output characteristic parameters of traveling wave tube.Under the existing experimental conditions,Use the LabVIEW software to create an automatic test system with the above parameters.The system can only complete the field parameters measurement,can not achieve long-distance online operation,so this article on the basis of the main completion of the following three parts:(1)Create a front-end web site based on the traveling wave tube automatic test system: Create a front-end site using the Apache / MYSQL / PHP portfolio development model,create a profile for the traveling wave tube,download center and user message.Some users may know about the definition and measurement principle of the relevant parameters of the traveling wave tube.Therefore,before the parameter measurement operation,you can log in to the website,understand the relevant theoretical knowledge of the traveling wave tube,or download the information and message exchange.(2)Create a back-end measurement system based on the traveling wave tube automatic test system: The back-end measurement system is used for on-line remote measurement of traveling wave tube parameters.The system is based on the B / S modeand bootstrap framework,The bootstrap framework has been optimized for improvement and has been integrated into the web-side graphics rendering library files Echarts and HighCharts.The work is as follows: 1)Create the main and auxiliary characteristic parameter measurement module of the traveling wave tube,and each parameter measurement item corresponds to five sub-function modules to complete the parameter measurement;2)Create a number of auxiliary function modules to measure the result;3)Create a measurement instrument management system,the use of equipment on-line management;4)discusses the measurement system instrument network measurement page specific implementation technology,and gives the five parameters of the actual measurement results.(3)to create a browser client corresponding to the desktop client: the webkit browser kernel and node.js technology combined to create a browser client corresponding to the desktop client,get rid of the browser restrictions,to the user There are two ways to carry out the remote measurement of the traveling wave tube parameters.
