工业监控系统中的分布式实时数据库研究

Distributed Real-time Database in Industry Monitor&Control System

分析了工业监控系统中的分布式实时数据库的的功能与特点、结构、数据对象和事务的种类。提出建立内存数据库保证系统实时性并讨论了PC机和嵌入系统上实现内存数据库管理的区别和难点。着重研究了根据数据相关度分配数据的分布机制的实现和基于价值函数的事务并发调度。为构建工业监控系统中的分布式实时数据库提供了一条思路。

This paper analyzes the function characteristics and structure of the distributed real-time database,data object and transaction＇s type in industry monitor＆control system.Presented construct a memory database to assurance the real-time requirement of the system.Discussed the difference and nodus of memory database management on PC and embedded system.Emphasized to research data portioning policy by analyzing the data＇s pertinency and concurrency transactions＇control based on value function.Provided a reference to construct distributed real-time database in industry monitor＆control System.
