Remote measuring and controlling system of motor rotor test-bed based on campus network

针对高校教育规模快速增长导致工科试验环境拥挤、资源不足等问题,采用虚拟仪器技术和LabVIEW软件平台Remote Panel发布技术,对网络实验室的体系结构、视频图像网络传输和网页融合技术进行研究,设计了基于B/S模式的电机转子网络测控实验室远程测控系统:在测控系统的HTML源文件中创建帧,该系统能够通过校园网在同一网页页面中显示实验室电机转子的监控图像和测控参数信息;用户可以利用校园网进行电机转子的位移测量、轴心轨迹测量、振动测量以及转速测量和控制等试验项目。实际运行结果表明,视频图像800像素×600像素时清晰度好,电机转子转速能够快速逼近网络用户设定值,误差为1%,振动信号和转速信号采集误差为1%,能够满足转子试验台远程测控网络试验的要求。

To solve the problems of crowded experimental environment and deficient experimental resource due to the rapid expansion of higher education, researches about the architecture of network laboratory, video image network transmission and web page fusion technology were performed based on the virtual instrument technology and the remote panel publishing technologies of L.abVIEW software platform, In this work, a remote measuring and controlling system of network test and control lab of motor rotor based on B/S mode was designed, which could display both monitoring image of lab＇ s motor rotor and testing parameter in the same web page by building frame in the HTML source file of the system, Clients can perform the test and control items, such as measurements of motor rotor＇s displacement, axle center orbit, vibration, rotating speed and so on, by using the system, The real running results in a campus network show that a 800 × 600 pixel of video image has high definition, the rotate speed of motor rotor can approach to the value pre-set by network users with an error of 1%, the signal acquisition errors for vibration and rotate speed are both 1% and all the parameters meet the demands of network experiment of remote measurement and control of rotor test - bed.
