| 摘 要： | 基于Zigbee通信技术的无线传感网是最具应用前景的一种网络模式，定位信息对网络数据有重要的辅助作用。文中提出了一种基于接收信号强度指示（ RSSI）值的无线Zigbee传感网测距定位技术，从理论上提出了基于RSSI的节点测距定位处理算法，并从实践上提出了CC2530测距定位模块实现方式。最后通过在实验室环境的实际距离与RSSI值的测试，得到了RSSI值与无线通信距离之间的实验结果，通过最小二乘法进行曲线拟合，得到了RSSI测距的实测公式。

| Abstract: | Wireless sensor networks based on Zigbee communication technology is one of most promising network patterns. The location information is very important and necessary assistance for sensory data. Propose one kind of range measurement technology based on RSSI for wireless Zigbee sensor networks in this paper. From the theory,the range measurement and location algorithm is proposed based on RSSI,and then the range measurement module of CC2530 is realized from practice. At last,the test between RSSI and the actual distance in the experiment is carried out,obtaining the experimental results. Throuth least squares curve fitting,the formula of practical measure-ment of RSSI range measurement is acquired. |
