【摘要】：行波管隶属于真空电子器件,随着对行波管研究的不断深入,其应用范围也随之逐年增加,且随着信息技术日新月异的发展,客户对行波管参数测量手段的要求越来越标准化和专业化。传统行波管参数测量方法费时费力,易受到时间、空间、设备等因素影响,使得测量效率和精度均受到较大限制,已不能满足当今社会需求。为了节省人力物力,远离某些危险测量环境,并提高测量效率和精确度,借助于计算机软件技术,创建基于行波管自动测试系统的远程客户端具有重要的现实意义。针对上述问题,本文详细论述了行波管参数测量方法的国内外研究现状,分析了行波管输入输出功率、增益线性度以及谐波输出比特性参数的定义及测量原理,在现有实验条件下,使用LabVIEW软件创建上述特性参数的自动测试系统。该系统只能完成实地参数测量,不能实现远距离在线操作,故本文在其基础上,主要完成以下三部分内容:(1)创建基于行波管自动测试系统的前端网站:使用Apache/MYSQL/PHP组合开发模式创建前端网站,在网站中创建了行波管简介、下载中心及用户留言等模块。某些用户可能对行波管相关参数的定义及测量原理等内容了解不足,故在进行参数测量操作之前,可先登录该网站,了解行波管相关理论知识,或者下载资料和留言交流。(2)创建基于行波管自动测试系统的后端测量系统:后端测量系统用于行波管参数的在线远程测量,该系统基于web端常用的B/S模式和bootstrap框架进行开发,对bootstrap框架进行了优化改进,并融入网页端图形绘制库文件Echarts和HighCharts。所做工作为:1)分别创建行波管主副特性参数测量模块,每个参数测量项对应5个子功能模块,用以完成参数测量;2)创建若干辅助性功能模块,用以对测量结果进行多方位展示;3)创建测量仪器管理系统,对所用仪器进行在线管理;4)论述测量系统仪器网络测量页面的具体实现技术,并给出5个参数的实际测量结果。(3)创建与浏览器客户端相对应的桌面客户端:将webkit浏览器内核和node.js技术相结合,创建与浏览器客户端相对应的桌面客户端,摆脱浏览器的限制,给用户提供两种方式进行行波管参数的远程测量。
[Abstract]:TWT belongs to vacuum electronic devices. With the development of TWT research, its application scope increases year by year, and with the rapid development of information technology, Customers' requirements for TWT parameter measurement are becoming more and more standardized and professional. The traditional TWT parameter measurement method is time-consuming and laborious, which is easily affected by time, space, equipment and other factors, so the measurement efficiency and precision are greatly limited, which can no longer meet the needs of today's society. In order to save manpower and material resources, keep away from some dangerous measuring environments, and improve the efficiency and accuracy of measurement, it is of great practical significance to create a remote client based on TWT automatic test system with the aid of computer software technology. In order to solve the above problems, this paper discusses in detail the research status of TWT parameter measurement methods at home and abroad, and analyzes the definition and measurement principle of TWT input and output power, gain linearity and harmonic output ratio characteristic parameters. Under the existing experimental conditions, LabVIEW software is used to create the automatic test system for the above characteristic parameters. The system can only complete the field parameter measurement and can not realize the long-distance on-line operation, so this paper is based on the system. The main contents are as follows: (1) create front-end website based on TWT automatic test system: use Apache / MySQL / PHP combination development model to create front-end website, create TWT brief introduction, download center and user message module in the website. Some users may not know enough about the definition and measurement principle of traveling-wave tube related parameters, so they can visit the website to understand the relevant theory of traveling wave tube before carrying out the parameter measurement operation. Or download data and exchange messages. (2) create a backend measurement system based on TWT automatic test system: the backend measurement system is used for on-line remote measurement of TWT parameters. The system is based on the B / S mode and bootstrap framework commonly used in web. This paper optimizes and improves the bootstrap framework and integrates the graphics drawing library files Echarts and High Charts. The main and secondary characteristic parameter measurement modules of TWT are created respectively. Each parameter measurement item corresponds to 5 sub-functional modules, which is used to complete parameter measurement. 2) create several auxiliary function modules. It is used to display the measurement results in many directions (3) to create the measuring instrument management system, and to manage the instrument on line. 4) to discuss the concrete realization technology of the measurement system instrument network measurement page. The practical measurement results of five parameters are given. (3) creating desktop client corresponding to browser client: combining webkit browser kernel with node.js technology, creating desktop client corresponding to browser client, getting rid of browser restriction. Two methods are provided for remote measurement of TWT parameters.
