射频网络与GPRS通信的可靠性与安全性设计

Transmission Reliability and Security Design Based on RF Network and GPRS

提出了一种基于nRF905与GPRS的远距离无线传输系统的设计方案,重点介绍系统通信协议的设计,成功解决了射频网络中的冲突检测、隐藏节点、差错控制及重发等问题,并在分析GPRS数据安全性因素的基础上给出了解决方案,保证了系统的可靠性与安全性。本系统设计的通信协议对其他无线通信系统的实际工作具有一定的参考和借鉴意义。

The paper presents a design scheme of remote radio transmission system based on nRF905 and GPRS.Communication protocols are introduced.The problems of conflict detection,hide node,error control and resend policy in RF network are solved.Based on the analysis of GPRS safety factors,the paper gives a solution scheme to ensure system reliability and security.The system communication protocols are of reference significance for actual practice of other radio transmission systems.
