通用无线分组业务(GPRS) 是一种基于全球移动通信系统(GSM) 的无线分组交换技术, 提供
端到端的、广域的无线IP 连接, 具有永远在线等特点。介绍了基于GPRS 网络的数据终端单元
(DTU) 。该单元是由以ARM芯片S3C44B0X 和GPRS 模块G20 为核心的硬件和软件组成。在概括
工业GPRS 监控系统构成的基础上, 介绍了GPRS DTU 硬件设计, GPRS DTU 软件是由μC /OSⅡ操
作系统、TCP / IP 协议、点对点协议组成。该单元使用户通过GPRS 网络实现用户设备和用户数据
中心之间的数据传输-General Packet Radio Service (GPRS) is based on Global System for Mobile Communications (GSM) wireless packet switching technologies to provide end-to-end, wide-area wireless IP connection, with always-on and so on. Presented data based on the GPRS network terminal unit (DTU). The unit is the ARM chip from S3C44B0X and GPRS Module G20 as the core hardware and software components. In the summary of the industrial composition of GPRS monitoring system based on GPRS DTU introduces hardware design, GPRS DTU software by μC/OS Ⅱ operating system, TCP/IP protocol, the composition of point-to-point agreement. The unit allows users to users through the GPRS network equipment and user data between the data center
