一种实时测控集群数据处理进程软件控制方法

在基于集群架构的实时测控系统上,通过软件设计实现一种满足数据处理实时性和系统高可用的集群数据处理进程控制方法。计算节点运行的数据处理进程采用多线程设计,对时间驱动线程和数据驱动线程分别设计了工作信号处理流程。实践证明方法不但能够保证计算节点完成数据处理任务的实时性和可靠性,还能动态完成集群节点的任务迁移和故障恢复,提高了测控集群系统的实时性和可用性,从而有效发挥集群系统架构在测控系统中应用的优势。

A Software-based Control Method for Real-time Data Processing in Measurement and Control Cluster System

In a real-time measurement and control system with the cluster framework, an effective software-based control method for the cluster data processing is designed, which can realize real-time data processing and high availability of the system. The multi-thread design is adopted in the data processing of the computing nodes, and the working flows for the time driven thread and data driven thread are designed respectively. Practice shows that this method can not only ensure the real-time performance and reliability of data processing, but also realize mission migration and fault recovery dynamically.This method improves the real-time performance and availability of the cluster system, which fully reflects the advantages of the cluster framework in the measurement and control system.
