ZigBee无线组网远程数据采集系统
1、实验内容：协调器建立Zigbee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
[cpp] view plain copy
//NewCoordinator.h
[cpp] view plain copy
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;
[cpp] view plain copy
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)
