实时多任务过程控制机软件设计

本文从实用角度论述了一种可用于分布式系统和用户控制任务相对独立环境的实时多任务过程控制软件的整体设计思想、软件结构和实现的一般方法。文中还分别给出了两级系统监控级和过程控制级软件的实例。

Multitask and Real-Time Software Design of Process Control Computer System

A practical multi-task and real-time software design method of progress control computer system, which may be a distributed one, is presented in this paper. The software is designed to several taskes with different priorities, and the taskes are allocated for their real-time requirements and synchronization. The taskes communicate with each other by sharing data resources. A user-task relativeiy independent upon the system ones is designed for real-time processing and control, which can be user-programmed. Two design examples of real-time systems for supervisory operation and process control are also discussed.
