| 摘要: |
| 在简述通用分组无线业务GPRS(General Packet Radio Service)系统特点的基础上，提出了基于固定IP通信主站和基于中转站的两种GPRS通信方案．后者只需借用他人的合法IP．同样的通信效果运行成本却大大降低。详细介绍了数传终端的硬件结构和工作原理．且讲述了如何针对不同的系统要求选择传输控制协议TCP(Transmission Control Protocol)或用户数据报协议UDP(User Data Protocol)．最后介绍了GPRS技术在铁路道口电源智能监控装置中的应用，该装置数据传输速率高，通信实时、可靠，在现场运行效果良好。 |

| Abstract: |
| According to the features of GPRS(General Packet Radio Service) network,the two pro-jects of setting up communication systems based on fixed IP or a transfer station are recom-mended. The communication system based on transfer station,which does not need own fixed IP,is as satisfying as the other. Furthermore,its cost reduces greatly when it runs. This article introduces the hardware structure of transmission terminals and their working principles in detail. It teaches us how to choose TCP(Transmission Control Protocol) or UDP(User Data Protocol) in different systems. At last,it shows the application of GPRS technology on intelligent monitor for power supply in the railway. The monitor is characterized by higher speed,real-time performance and reliable com-munication. Its application in the actual locale of working is proved successful and steady. |
