| 摘 要： | 为测试嵌入式实时操作系统μC/OS-Ⅲ的实时性,设计了基于ARM Cortex-M3内核的实验平台.该平台由波形发生模块、ARM Cortex-M3硬件模块、单片实时信号采集模块和实时操作系统采集模块4个部分构成.基于STC89C52构建波形发生模块,基于STM32设计ARM Cortex-M3硬件模块,并在STM32上开发实时信号采集模块和实时操作系统采集模块.实验表明,实时操作系统采集模块采集一次比实时信号采集模块消耗更长的时间,且消耗的时间与任务个数成线性关系.

| Abstract: | For the special groups of the elderly in welfare centre,a design of nursing system based on ZigBee technology is put forward.The system can timely locate the sphere of activity of the elderly in welfare centre by means of establishing wireless sensor network,and report to the monitoring center when the elderly is about to be out of the monitoring area or fall over etc.The system has the advantages of low power consumption,small size and high stability. |
