计算机技术和通讯技术的发展推动着控制系统由集散控制系统和分布式现场总线控制系统向着开放的、标准化的网络控制系统发展,字符显示器也随之从专用走向了通用。字符显示器具备操作控制、状态监视、参数设定、网络通讯等功能,为用户提供友好的操作界面,完全可以替代传统的控制面板,因此在纺织、印刷、制药、水利等诸多行业中得到广泛的应用。 本文以网络控制系统节点——字符显示器的开发为具体的研究对象,选取C8051F310单片机作为硬件平台核心,采用KEIL开发软件平台,实现了一个通用字符显示器。 论文首先介绍网络控制系统的发展历程以及字符显示器的应用现状及发展概况,然后介绍字符显示器的功能及体系结构,在体系结构中概述系统的软、硬件设计框架。本文的重点是介绍字符显示器的硬件平台开发、软件平台开发、可重构通信原理与实现。在硬件平台开发中着重介绍硬件平台的设计原则以及硬件各模块的设计原理与分析;在软件平台开发中介绍了组态文件结构设计以及软件各模块的设计与实现和软件优化;在可重构通信的原理与实现中着重介绍可重构通信在字符显示器中的实现。本课题的目地是开发一个通用型字符显示器产品,同时探索控制系统的硬件软件协同设计的方法,并将重构通信原理运用到实践中,为今后的深入研究打下基础。 论文结尾对全文进行了总结,并对系统的下一步工作做了一个展望。
With the development of computer technology and communication technology, the control systems are driven from the DCSs and DFCSs to the open and standardized networked control systems, and character display are tending from the special toward the universal. Character display has functions of operation control, status monitor, parameter set and network communication, gives users friendly interface, replaces the traditional control panel absolutely, therefore it is widely used in textile, printing, pharmacy and water conservancy. Character display which is one of networked control systems nodes is taken as a concrete research object. The universal character display is realized by selecting C8051F310 as hardware core and using Keil to develop software. Firstly, the development process of networked control systems and the application actuality of character display are introduced, then illuminates functions, requirement and architecture of character display. The emphasis of this paper is the design of hardware and software platform and the principle and realization of reconfiguration communication. In the design of hardware platform, the design principle and analysis of hardware module and the design principia of hardware are emphasis; in the design of software platform, the structure design of configuration file, software module design and realization and software optimize are introduced; the theory of reconfiguration communication is applied in the realization of character display, which is other emphasis. It is the aim of this project to develop a universal character display, to explore the co-design of method of software and hardware and to apply reconfiguration communication to practice, which is base to further research in future. The end of this paper is the summary of the whole thesis and the outlook of the next work for this system.
