摘要
主要给出了基于无线收发模块nRF905的无线数据传输系统,如设备数据(家庭内部三表或多表数据)的通信,从而实现了数据的无线传输的系统设计方案。首先介绍了nRF905的结构,工作模式以及接收和发送数据的工作流程,其次介绍了系统的总体结构及硬件实现,最后又详细地介绍了通信协议的设计,其中包括路由协议和数据传输协议。文章通过构建合理的通信协议,有效地解决了节点间通信寻址问题,保证了通信的可靠性。
Based on the transceiver nRF905, a type of wireless data communication system is designed, which can transfer data wirelessly such as the communication among device data （data of three or more meters in family）. First, the structure, working model and saving and receiving working process of nRF905 is introduced, then, the structure of a system and the design of its hardware are given; finally the design of communication protocol is described. By providing a reasonable communication protocol, the addressing problem is settled well to assure the high reliability of communication. The system has a good effect in practice
