摘　　要：基于433 MHz频段设计了一套无线传输解决方案,实现了一种基于对等网络的无主机信息共享系统。本方案中通过移交主机权的方式实现了广播发射机乃至信号覆盖区域的自适应切换,最终使所有节点都完整地接收到数据包。方案中每个节点均使用FPGA为主芯片,经系统测试,在100 m W以内的发射功率下,每个节点覆盖半径可达100 m,传输速率最高可达8 kb/s。本设计提供了一种网络式的数据传输方式,有良好的应用价值。In this paper,a wireless transmission solution based on band 433 MHz was designed to realize a kind of non-host information sharing system in peer-to-peer networks. Host handover in all radio transmitters in the signal coverage area can be adaptively switched,and eventually,all nodes completely receive the whole package. Each node uses FPGA chip. The testing results show that each node covers up to 100 m,and transmission rate is up to 8 kb/s,under the transmission power of 100 m W. The design provides a way about network data transmission,which has good application value.
