1-15 实验12 ZigBee无线传感器网络远程数据采集系统

ZigBee无线传感器网络远程数据采集系统

1、实验内容：协调器建立网络，路由器和终端节点加入网络，然后周期性地采集温度和电压发送给协调器，协调器通过串口发送给PC的串口调试助手

2、补充：（为了便于数据的传输和管理，传输的数据用一个结构体表示）如下

//NewCoordinator.h

typedef union h
{unsigned char databuf[18];struct RFRXBUF{unsigned char head[2];  //  "&&"unsigned char type[3];  //  "ROU"或 "END"unsigned char myNWK[4]; //  自身的网络地址unsigned char pNWK[4];  //  父节点的网络地址unsigned char value[4];  // value[0]表采集数据的类型  如：W表温度  V表电压 后面几位表数值unsigned char tail;     //"&"}BUF;
}RFTX;

上面是个联合结构体，便于数据的强制类型转换。

3、程序设计

协调器程序设计(负责接收来自路由或终端节点发送来的数据，并通过串口发送到PC的串口助手进行显示)
