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

学会一个程序语言,是一回事儿;学会如何以此语言设计并实作出有效的程序,又是一
回事儿。C++ 尤其如此,因为它很不寻常地涵盖了罕见的威力和丰富的表现力,不但建立
在一个全功能的传统语言(C)之上,更提供极为广泛的对象导向(object-oriented)性质,
以及对templates 和exceptions(异常状态)的支持。
Lostmouse编写的非常出名的C++学习资料,适用于有一定的C++编程经验的同学。-Institute a program language, it is one thing to abuse learn how to use this language to design and make a real and effective procedures, it is one thing to abuse. C++ Especially because it was unusual to cover a rare power and wealth of expression, not only based on a full-featured traditional language (C) above, but also provide a wide range of object-oriented (object-oriented ) nature, as well as templates and exceptions (abnormal state) support. Lostmouse prepared very well-known C++ Learning materials, applicable to a certain degree of C++ Programming experience of students.
