摘要
以ARM7EJ-S微处理器的MT6226芯片为核心,阐述了在Nucleus实时操作系统下实现气象数据采集的设计方案。给出了硬件设计框图,同时根据气象数据的特点采用了优先级和时间片轮转法相结合的调度算法对系统任务进行划分,实现各种任务的并行执行,从而提高了资源的利用率,使整个系统运行更加稳定。
In this paper, a design concept of meteorological data acquisition system based on ARM processor MT6226 and real-time operating system Nucleus is described, as well as its hardware block diagram. At the same time, considering the characteristics of meteorological data, an algorithm integrating priority and time slice cycle is adopted in order to partition the system tasks and run every task in parallel. So it can increase resources utilization efficiency and makes the system work more stability.
