| 摘 要： | 针对继电保护装置对实时性、可靠性要求很高的特殊应用需求,提出一种基于逻辑栈和三值信号量的嵌入式实时操作系统的模型—YZ_RTOS。在内核算法实现上,按照任务实时性要求的不同,将任务分成8个等级。给出了基于有限状态机的调度和同步描述。测试结果表明,YZ_RTOS占有很小的程序空间和数据空间,在实时性、可靠性方面具有很高的性能,满足了继电保护的应用需求。

| Abstract: | Relay protection set emphasizes on high real-time and reliability,in order to meet these special application requirements,in this paper,an embedded real-time operation system model based on logical stack and three-value semaphore:YZ_-RTOS is proposed.In the core algorithm implementation,tasks are divided into eight levels according to different timely requirements.Finite state machine based specification for schedule and synchronization is presented.Test results indicates that YZ_-RTOS consumes very little program space and data space,and a high performance on real-time and reliability is achieved.These may be sufficient to the requirement of relay protection application. |
