【摘要】 嵌入式系统(Embedded System)是当今最热门的概念之一,目前,国内一个普遍被认同的定义是:以应用为中心、以计算机技术为基础,软件硬件可裁剪,适应应用系统对功能、可靠性、成本、体积、功耗严格要求的专用计算机系统。另外,凡是与产品结合在一起的具有嵌入式特点的控制系统都可以称为嵌入式系统。 嵌入式系统是继IT网络技术之后,又一个新的技术发展方向。由于嵌入式系统具有体积小、性能强、功耗低、可靠性高以及面向行业应用的突出特征,目前已经广泛地应用于军事国防、消费电子、网络通信、工业控制等各个领域。 目前,嵌入式智能平台(EIP:Embedded Intelligent Platform)作为嵌入式系统的一个分支,国内外对它的研究、开发工作更是如火如荼。它正在影响我们每个人的生活方式,金融、电信、教育、军工等都是新兴的行业热点。而单板计算机在这一平台中起着重要的作用。嵌入式单板计算机就其原理和功能来说也就是PC,只是由于它体积非常小,可以嵌入到其它产品中,使其具备PC的功能。 本文在嵌入式系统的一个分支领域做了重点地研究,即嵌入式单板计算机的人机界面应用。 人机界面是嵌入式系统很重要的一部分,用于系统与人的交互。人机界面可以使用键盘、液晶等部件,还可以使用I/O单元,方便与人的交互操作。基于人机界面的重要性,本文选用了主板卡EC3-1542CLDN嵌入式单板电脑,与嵌入式开发板FS44BOX相结合加以运用,做了人机界面的应用研究。并在此基础上,设计了瘦客户机(NC:Network System)系统。更多还原

【Abstract】 Embedded System is one of the most important concepts all over the world. At present, Embedded System is defined widely in our country as follows: It is the special system of computer focused on the application, and based on the technology of computer, while it can be clipped in software and hardware, and can be adapted to the system of application that is strict on the function, reliability, cost, cubage and dissipation. Otherwise, the controlling systems with the features of the embedded system in product can also be called Embedded System.Embedded System is another new aspect of development in technology after the IT network. It has the advantages as follows: smaller cubage, better performance, lower cost, higher reliability, and direct to the industry application. As a result, it has been applied in the fields of military affairs, national defense, consumed electron, network communication and industry control.At present, EIP (Embedded intelligent platform), as a branch of the Embedded System, has been developed and researched all over the world. The life style of us has been influenced: especially in the fields of finance, telecom, education and so on. SBC (Single Boar Computer) plays an important part in EIP. Embedded SBC is similar to the PC in the aspect of theory and function. But it has smaller cubage which has the function of PC, so it can be embedded in many systems.In my paper, HMI (Human-machine interface) based on embedded single board computer, as one of the branch of embedded system, has been researched.HMI is one of the most important parts of Embedded System .It has been used in the interaction between human and machine. HMI can make use of the keyboard, LCD, I/O unit and so on. In my paper, I select the SBC EC3-1542CLDN board, and the embedded developing board FS44BOX, to make the research of HMI, and design the system of NC (Network computer).更多还原
