穴盘播种控制器中的多任务分析与实现

Analysis and Realise of the Plug Seedling Controllor' s Multi-test

在穴盘播种控制器的软件系统开发时,通过对穴盘播种控制器中存在的任务进行分析,运用实时系统前后台编程方式,合理使用单片机的中断系统,进行了播种器的控制软件设计。最后对软件性能进行了分析。经实际运行结果表明,该软件系统可以很好地满足播种器的实际工作要求。

When developing the software of the plug seedling sower'controller, this paper designs a controlling software following a foreground/background way and properly using the interrupt of the singal-chip controller. The softwar is disgned based on analyzing all tests of the plug seedling sower'controller.Finally,it analyze the character of the software system. The result of the experiment improved that this software can fufill the sower's working requestment.
