摘要上下位监控系统在工业及其他领域中得到越来越广泛的应用,实时的实现及其可靠性是系统的关键。文章讨论了基于RMS的实时任务调度算法及其在弱实时上下位监控系统中的应用,并给出了具体的应用实例。 关键词弱实时任务调度上下位系统 Abstract The master and slave computer system has been widely used in industrial processes and other fields. The implementation of real time and its reliability are the critical issue of the system. The RMS based real-time task scheduling algorithm and its application in low priority real time master / slave monitoring system are discussed in the paper. The practical example of application is also given. Keywords Low priority real-time Task Scheduling Master and slave system
