【摘要】 开发了基于虚拟仪器的种子清选机测控系统,降低了系统的硬件费用、缩短了开发周期,增强了系统的扩展能力。软件设计采用多线程技术,使得多任务系统得以高效率和高可靠性地实现,尤其增强了主控制台界面的实时操作性。同时,采用多种软件平台混合编程,优化人机界面。本文给出了设计思路、总体方案和软硬件实现的方法。更多还原

【Abstract】 A system of performance testing for seeds cleaner has been developed. It is based on the virtual instrument and economizes its hardware investment. The system is composed of parameters measuring and controlling system. As a characteristic, multithreading technique is used in the software and it makes possible that many jobs can be finished in the same time. This paper gives its studying way and whole project of hardware and software.更多还原
