基于GPRS网络的嵌入式终端平台的研究与设计
|
摘要
通用分组无线业务(General Packet Radio Service，GPRS)是在现有GSM技术基础之上发展而来的一种新的承载业务。GPRS网络提供了基于IP的分组交换数据业务，这就使得终端用户可以通过GPRS直接访问最大的分组数据网络(PDN)---Internet。近年来，随着GPRS移动通信业务的产生和全面投入使用，其应用领域越来越广泛。高速的数据传输、永远在线和实行按流量收费的资费方式，使得GPRS通信业务在环境保护、道路交通、商务金融、移动办公等行业具有无可比拟性价比优势。
针对当前许多行业的传统数据终端需要远程联网的要求，结合当前最新的嵌入式技术、移动通信技术和TCP／IP技术，利用基于ARM920T的三星S3C2410微处理器、西门子最新的无铅GPRS模块MC39i和基于Linux操作系统开发平台，设计数据接入终端平台，内嵌TCP／IP协议，能方便地通过GPRS网络接入互联网，进行远程无线数据传输。
本文的主要研究内容是基于GPRS的无线传输技术，并且利用32位嵌入式系统ARM微处理器和嵌入式Linux平台，实现无线数据平台终端的设计。本课题所涉及到的应用技术：GPRS是目前的GSM无线网络向3G过渡重要环节；基于ARM体系结构的硬件微内核及Linux内核裁减技术是最近几年发展起来并且已经在国内外得到广泛应用的新技术。本课题基于ARM微处理器S3C2410的设计采用华恒公司的S3C2410核心板进行二次开发，并对核心板进行Linux操作系统移植。
The GPRS (General Packet Radio Service, GPRS) is developed from the basis of the existing GSM technology, a new bear service. GPRS network provides packet-switched data services based on internet protocol (IP), which makes the end-users can directly access to the external packet data network (PDN) ---Internet. In recent years, with the development of GPRS, more and more application of GPRS are widely used. High-speed data transmission, permanent online and the expense is according to the flux of data. GPRS communication service has high capability and low price, it can be used in Environmental Protection, Road Traffic, Business and Financial, Mobile Office, etc.
In view of the current many traditional data terminal need remote network requirements, in connection with the latest embedded technology, the mobile communication technologies and the TCP/IP technology, utilizing Samsung S3C2410 based on the ARM920T microprocessor, Siemens MC39i latest unleaded GPRS module and the development platform based on the Linux operating system, designs Data Access Terminal Platform which inner embeds TCP/IP protocol, can conveniently access to the internet through GPRS network and carries on the long-range wireless data transmission.
The main study was based on GPRS wireless transmission technology, and the use of 32-bit ARM microprocessor embedded systems and embedded Linux, realized the terminal design of wireless data platform. The application technology that the subject involves: At present the GPRS is important link of that the GSM wireless network transfer to 3G, In recent years based on ARM system micro-architecture hardware and the Linux kernel cut down techniques have been developed and already used widely as new technology at home and abroad in recent years. The design based on ARM microprocessor S3C2410 of this subject adopts S3C2410 main board of the HuaHeng company to carry on the secondary development, and carry on Linux operating system to transplant to the main board.
