基于CVI和ASP．NET的测试数据获取方法

为解决某型装备维护性测试过程中数据采集自动化水平较低的问题，考虑测试设备分散在不同测试点，且需频繁切换，各个测试岗位有严格的人员分工，同时又不便为各测试点单独配备工控机，提出一种利用手持设备获取测试数据的方法；该方法基于CVI程序向仪器发送SCPI指令获得测试数据；仪器端操作人员通过手持设备浏览器访问控制界面；巧妙运用MySQL数据库作为SCPI指令发送枢纽；运用该方法实现测试过程中的协调控制，增强系统的适应性和灵活性，满足现场操作相关要求，较大提升了数据采集和管理的自动化水平。

Acquisition Method of Test Data Based on CVI and ASP.NET

To improve the automation level in data acquisition process of certain equipment,considering that the test equipments were scattered in different test points,and need to be frequently switched,and each test posts had strict personnel division,and at the same time,it was not realistic to provide computers for individual posts,a method of using handheld devices was put forward to get test data.Based on the CVI program,the method sent SCPI commands to instruments and obtained test data;Instrument operator logined the control interfaces through browsers of handheld devices;The MySQL database was skillfully applied to be a delivery hub of SCPI commands.The method which enhanced the system’s adaptability and flexibility can realize coordinating control in data acquisition process and meet the field operation requirements.Thus,the automation level of data acquisition and management is significantly improved.
