摘要本文的主要研究内容是太阳自动跟踪装置控制系统的研究,在前人研究的基础上作了进一步的开发,吸取了前人研究的精华,补充了前人研究的不足。本系统是基于虚拟仪器软件,将光电跟踪方式和时间跟踪方式用一种新的方法(两种方式同时采用,而非相互切换)结合在一起,使系统运行更加稳定,便于文护和安装,提高了系统的追踪精度、可靠性,降低了整个装置的整体成本。本系统能够全天候自动工作,在晴天光线足够强的情况下,系统会根据时间跟踪和由光电跟踪系统产生的轨迹调整量进行跟踪,提高了跟踪精度,避免了由于环境干扰在只采用光电跟踪时会发生紊乱的问题。于光电跟踪的修正作用,系统的安装精度要求不高,降低了装置的安装成本,便于装置的普及和应用。8115

Title The research of solar energy automatic tracking system based on virtual instrument
Abstract
The main contents of this paper is the study of the sun automatic tracking device control system and made on the basis of previous research for further development. I have drew on the essence of the previous studies and supplement the lack of previous studies. This system is based virtual instrument software and uses a new method of combine optical tracking and time tracking mode (using the two methods at the same time, rather than interchanged) in order to make the system more stable, easier to maintain and install, improve tracking accuracy and reliability and reducing the overall cost of the entire device. The system can weather work automatically. In the case of that sunny light is strong enough , the system will track orbit which generated by time tracking and the optical tracking system. It will improve the tracking accuracy, avoid the disorders which would occur in the case of only using the optical tracking. System installation accuracy is not required, which reduces the cost of installation of the device. It is easy for the popularization and application of the device.
Keywords:Virtual Instrument, Automatic tracking, Time tracking, Electro-optical tracking
