基于任务调度的电能量计量采集系统的设计与实现

任务调度是分布式采集系统环境下高效利用采集资源、快速完成大量的数据采集任务的一种有效方式。本文根据电量数据采集的特点,提出了基于分布式系统的体系结构及任务优先级的任务调度与负载均衡的模型,分析了数据采集的任务分配模式及其工作原理,讨论了任务粒度对动态分配效果的影响,提出了动态分配模式下的任务分配策略,同时对模型的特点进行了较为详尽的分析。工程运行的实践证明,该系统具备良好的可扩展性和对采集任务的快速响应。

The Design and Realization of Tele Meter Reading System Based on Task Scheduling

Task Scheduling is an effective measure of transporting large mounts of meter data within a short period. On the basis of the characteristics of data collection, and task schedulers, this article proposes the structure of distributed server and a priority-based task scheduling and load balancing model, and then analyzes the model in a detailed way. Application of the system shows that the model provides good scalability and fast responsibility .
