基于linux的arm嵌入式系统设计 摘 要 文章在介绍了嵌入式系统和嵌入式操作系统的基本知识基础上，指出了linux作为嵌入式操作系统所具有的优势,并给出了基于Linux的arm嵌入式系统开发设计中应该注意的一些方面。 在以计算机技术，通讯技术相结合的信息时代的快速发展和互联网的广泛应用的形势下，3C合一的趋势已经形成。其结果必然就是将计算机工业的中心从计算机产品转移到信息产品，从而出现信息电器的概念。在信息电器的应用开发领域，由于需要的功能不断的增加，嵌入式系统也就将成为软件业的新宠儿。同时在计算机本身的领域里面，微型化和专业化成为了发展的趋势，同样也需要嵌入式系统的支持。 在另一方面，稳定、可靠的电量远程秒表一直是店里部门和电力运营商迫切解决的问题，而目前电量的远程表大都是基于人工或电力线载波、专用通信网实现，这些方案因各种原因不能完全满足现代用电管理的要求。 关键字:嵌入式系统;?Linux;?嵌入式操作系统;?arm;图形用户接口 Abstract With the development of Computer technology and Cmmmunication technology in information times and the board application of internet ,it is clear that 3C (Computer,Communication and Consumer)will converge in the near future which will lead the focus of Computer Industry from the compute product to information product.It is the concept of Informationo Appliance,Embedded Operating System will be the most favorite thing in Software Development field.At the same time,in the field of computer science itself,the miniaturization and specialization is the new direction of the computer world.It also wants the support of Embedded System. On the other hand,steady and reliable remote meter for reading electricity is the required urgently for solving problems of electric power department and electric power operation business.At present,remote meter reading of electricity is mainly realized by manpower or power line carrier or special communicating net.These schemes cannot satisfy modern managing requirement for various reasons. Under this background,I take charge of designing and developing the data concentrator of second-generation Remote Meter Reading System during the procedure of my thesis work.Using 32-bit MCU AT919200 as the core,the data concentrator is based of Embedded Linux Operating System,and has outstanding data management and network communication ability.My thesis work includes the general project design,transplant of Operating System and application software design.
