摘要
介绍了GPRS网络的基本概念和特点,阐述了基于GPRS网络的分布式远程无线数据传输系统的设计方案。首先重点分析并设计了自定义格式的数据帧,制定相应的应用层传输协议,给出了在数据中心端动态添加W insock控件用来接收数据,并对接收到的数据帧进行拆分校验的函数算法设计。最后,给出了核心功能的部分实现代码。经应用实践证明,本设计方法简便易行,对其他GPRS无线应用系统设计有一定的参考价值。
This paper introduces the basic concept and features of GPRS network. It sets forth the project scheme for the remote wireless data transmission system in distributing model based on GPRS network. Firstly,in this paper it puts a great emphasis on the analysis and project of the data frame with the custom format, and establishes the corresponding transferring protocol at the application layer. Secondly, it appends Winsock control dynamically in data centre for receiving the data, and projects the function calculation used in the splitting and checking of the received data frame. Finally, it gives partial practical codes for the core function. Proven by the practices, the project put forward by this paper is convenient and feasible. It values a lot to other GPRS wireless application systems design.
