基于SEP3203处理器的DTU点对点数据传输

DTU Point to Point Data Transmission Based on SEP3203

无线数据终端点对点数据传输是指终端之间通过网络相互进行数据传递的通信。提出了基于嵌入式系统和GPRS技术的DTU点对点数据传输的两种方案及其实现过程。方案一通过移动公司的CMNET接入Internet,DTU获得动态IP地址,进而进行终端间的数据传输;方案二使用移动公司根据用户需求为用户组建的APN专网,DTU根据需求可以固定IP地址,实现终端间的数据传输。DTU的组网方式采用TCP/IP典型的C/S模式。

DTU point to point data transmission solves data transmission between DTUs via Internet. In this paper, we advance two ways based on Embedded System and GPRS communication technology to implement DTU point to point data transmission. One way,DTU will gain a dynamic IP address by connecting to the Internet through the CMNET server to transmit data between DTUs,the other way it can also be configured a static IP address by connecting to APN, a special VPN built by CHINA MOBILE to realize data transmission. DTU uses C/S model typically in TCP/IP protocol.
