基于ARM和μC/OS-Ⅱ的全自动测硫仪的设计与实现

The design with realizes of automatic measuring sulfur instrument based on ARM and μC/OS-Ⅱ

针对传统测硫仪存在实时性差的问题,设计一种基于ARM和μC/OS-II的嵌入式全自动测硫仪。本文给出了系统的软硬件设计与实现,并对μC/OS-II进行了移植。测试结果表明,任务切换时间约为510us,各任务运行无明显滞后。与传统的测硫仪相比,极大的提高了系统的实时性和稳定性。

By analyzing the poor real-time of domestic and international measuring sulfur instrument, the implementing strategy of an automatic measuring sulfur instrument based on ARM and μC/OS-Ⅱ real-time inner kernel is presented.First, the design of bard- ware and software system is presented.Then shared the plantation of μC/ OS-Ⅱ. The test result indicated that the task switching time approximately is 510us.Compared with traditional measuring sulfur instrument, system performance at the real time and reliability is improved greatly.
