整个无线通信演示系统由ABCD四个节点组成，根据硬件前端的实现，每个节点在收到与自己地址对应的数据包时触发同步信号，所以就需要一个中心节点来进行同步触发，本系统中以A节点为中心节点，B、C、D三个节点地位对等。A节点周期性的广播同步信息，从而实现四个节点的同步。A节点连接一台PC机，用来监视网络的情况并显示从其它节点发送过来的图像流信息。该软件可以实时对串口进行监听并显示A节点的路由表、网络的时隙表和吞吐量，实时获得B、C、D三个节点的图像流数据。-The wireless communications demonstration system consists of four nodes ABCD, depending on the hardware front-end implementation, each node address received with their corresponding data packet triggered synchronous signal, so we need a central node for syncing trigger, this system A central node to node, B, C, D status of the other three nodes. A node periodically broadcasts synchronization information in order to achieve synchronization of the four nodes. A node connected to a PC, used to monitor the situation of the network and displays from other nodes to send information over the image stream. The software can monitor real-time on the serial port and displays the A node routing table, the network time slot table and throughput, real-time access to B, C, D are three nodes of the image stream data.
