Posix线程同步机制及其在电网监控系统中的应用

Posix Threads Synchronization Mechanism and Its Application in Distributed Power Network Monitoring System

分析了UNIX/LINUX平台常用的多计算任务并发中的任务间通信的手段,针对其在任务间需要大量数据通信情况下的效率问题,提出了利用多线程及其同步机制来实现多计算任务的并发处理。结合一个分布式电网监控系统通信程序的实例阐述了其完整过程。

Analyzes some communication measures usually used in interprocess on UNIX/LINUX platform. For their low efficiency in frequent data communication among multitasks,brought forward a measure that use multithreads and its synchronization technique to realize the multitask concurrently process. It's proved by experiments that this method resolved this type of problem finely.An example is given to show the whole routine of multithread and synchronization control in the distributed power network monitoring system.
