摘　　要：针对传统单片机交流同步采样系统不具备现代操作系统管理功能的不足,介绍了一种基于μC/OS-Ⅱ实时操作系统内核的交流同步采样实现方法。该方法将采样过程分为频率动态跟踪和等间隔同步采样两部分,分别由优先级不同的多个任务完成信号采样和数据处理,各任务由抢占式的μC/OS-Ⅱ统一调度管理,较好地解决了精确性和实时性的矛盾。利用操作系统提供的API函数,可简化应用程序的编写,便于系统的功能扩充,并为分布式电力系统监控奠定基础。Directed to the traditional SCM which didn＇ t have the managing ability of the modern operating system in the AC synchronization sampling system, introduced a method of AC synchronization sampling that was based on μC/OS-Ⅱ operating system kernel. The method divided the sampling process into two parts, frequency dynamic, track and same - internal synchronization sampling. The tasks which process the different priorities, used to sample the signal and treat with the data. All tasks were scheduled by the preemptive μC/OS-Ⅱ kernel. The method has decreased the conflict between the precision and the real - time property. The application programming interface functions which are provided by the operating system, can simplify programming, and is convenient to expand the application system. The method is the foundation of the distributed power system monitor.
