【摘要】： 以嵌入式微处理器和嵌入式操作系统为核心的嵌入式技术,已在很多领域得到了广泛的应用。由于互联网的应用日益普及,信息共享的程度不断提高,传统的串行通讯和并行通讯方式的缺点日益凸出,嵌入式设备的网络化已经成为网络发展的必然趋势。Forrester Research的研究显示,到2010年,将有95%的连网设备不再是传统的计算机,而是带网络功能的嵌入式系统。本文根据在PC104系统下实现网络通信功能的成功案例,构建了基于ARM7微处理器和uCLinux操作系统的实验平台,完成了网络接口设计,并实现了嵌入式系统的网络通信功能。本文采用PHILIPS公司的LPC2210微控制器作为主控芯片,采用高度集成的以太网芯片RTL8019AS作为网络接口。选择Linux操作系统进行裁剪和移植,分析并实现了嵌入式TCP/IP协议栈。编写了底层网络驱动程序,实现了嵌入式硬件平台和PCLinux系统之间的基于网络的数据传输;同时实现了嵌入式系统同WindowsXP系统之间的基于网络的数据传输;通过对比实验,对网络数据传输协议和算法进行了研究和优化,完善了ARM嵌入式系统的网络功能。大量的数据传输及可靠性测试实验表明,本文所设计的嵌入式系统网络功能在可靠性、可用性及操作方便性方面都达到了预期的目标,具有实际的应用价值!
[Abstract]:Embedded technology based on embedded microprocessor and embedded operating system has been widely used in many fields. As the application of Internet is becoming more and more popular, the degree of information sharing is increasing, the shortcomings of traditional serial communication and parallel communication are becoming more and more obvious, and the network of embedded devices has become the inevitable trend of network development. Forrester Research research shows that, By 2010, 95% of networking devices will be embedded systems with network capabilities instead of traditional computers. According to the successful cases of network communication in PC104 system, the experiment platform based on ARM7 microprocessor and uCLinux operating system is constructed, the network interface design is completed, and the network communication function of embedded system is realized. In this paper, the LPC2210 microcontroller of PHILIPS Company is used as the main control chip, and the highly integrated Ethernet chip RTL8019AS is used as the network interface. The embedded TCP/IP protocol stack is analyzed and implemented by selecting Linux operating system for cutting and transplanting. The underlying network driver is written to realize the network-based data transmission between the embedded hardware platform and the PCLinux system, and the network-based data transmission between the embedded system and the WindowsXP system is realized. The network data transmission protocol and algorithm are studied and optimized, and the network function of ARM embedded system is improved. A large number of data transmission and reliability testing experiments show that the embedded system network function designed in this paper has achieved the expected goal in reliability, usability and ease of operation, and has practical application value!
