Some problems are caused by the periodic timer interrupt in μ C/ OS-ⅱ, so the improving algorithm for the timer is proposed and implemented to solve the problems. 针对μC/OS-Ⅱ实时操作系统中周期性时钟节拍服务出现的一些问题,该文探讨了一种时钟改进算法。
Wireless sensor network combine two working mode of periodic monitoring and interrupt for the purpose of long time information collecting and early warning over-limited parameter. 无线传感器监测网络结合了周期巡检与中断两种工作方式,可以对煤矿环境进行长期的信息监测,并且对超限参数进行中断预警以将事故消灭在萌芽状态。
