摘要
为了提高移动监测系统中实时数据的可靠传输,以CDMA 1X为主通信网络、GPRS为备份通信网络的方式构建了双网络数据传输系统。文中介绍了GPRS、CDMA 1X两种移动通信网络的结构和基本原理,针对GPRS无线数据传输使用的特殊性,详细分析了其在使用过程中可能出现的几种组网方案,基于TCP/IP网络协议,实现了GPRS无线数据传输,并构建了远程数据采集与控制系统。
In order to improve the reliable transmission of real-time data in moving inspection system, a dual-network data transmission system, which employs CDMA 1X as primary network and GPRS as backup network, is designed. The configuration and rationale of the two networks which include GPRS and CDMA 1 X are described in this paper. Focusing on the particularity of using the GPRS wireless data transmission, some modes of construction in the system are enumerated in detail. Based on the TCP/IP network protocol, the GPRS wireless data transmission terminal is designed, and the CDMA 1 X/GPRS long-distance data acquisition and control system is established.
