远程实验操作平台设计与实现
|
摘要
以迈克尔逊干涉仪为研究对象,设计了一个由自动测量模块、操作模块、监视模块、交互模块和控制模块构成的远程实验操作平台。自动测量模块采用OV7725摄像头摄像分析干涉条纹的方法实现条纹的自动计数;操作模块通过步进电机和细分驱动器实现微调手轮的远程操作;监视模块通过网络摄像头实现条纹"冒出"或者"缩进"现象的远程监视;交互模块通过W5200以太网芯片、LCD触摸屏和QT界面实现远程实验操作人员和实验现场指导人员的远程交互;控制模块采用K60高速处理器实现其他4个模块的控制。实验结果表明:利用该平台可顺利地远程完成迈克尔逊干涉仪实验的全部环节,并且干涉条纹监视效果清晰,测得的He-Ne激光波长结果误差最大不超过1.3/‰。
For the needs of long-distance open experiment teaching and remote experiment operation,with Michelson interferometer as the experimental object,the authors design a remote experimental platform which consists of automatic measurement module, operating module, monitoring module, control module and interaction module. Automatic measurement module uses OV7725 camera to analyze fringes by automatically counting the number of fringes; operation module realizes the remote operation of fine-adjustment hand wheel by step motor and subdivision drive; monitoring module realizes the remote monitoring for the phenomena of stripes " emitting " or " shrinking "; interaction module realizes the remote interaction between local instructor and remote experimenter by W5200 Ethernet chips,LCD touch screen and QT interface; control module realizes the control of other four modules by K60 high-speed processor.Experimental results show that all link of Michelson interferometer experiment can be successfully completed by the use of the platform,the monitoring effects of interference fringes is clear,and the maximum error result of He-Ne laser wavelength measurements does not exceed 1. 3 / ‰.
