摘　　要：基于RSSI测距技术,因其成本低和低复杂度,被广泛应用于无线传感器网络基于距离的定位技术中。本文采用TI射频芯片CC2530设计节点,软硬件结合实现网络通信功能,编写软件通过不同等级的功率、不同距离的测量实现了RSSI值的提取。实验结果表明,在不同测量距离内,传输损耗值是不同的,测量距离越小,损耗值越低,反之越高。通过测量值拟合得出的距离与信号强度的关系图,证明了基于CC2530的RSSI测距技术是有效的,适合短距离的一种距离测量技术。Distance measurement technology based on RSSI, because of its low cost and low complexity, is widely applied in the range-based localization of the Wireless Sensor Networks. Through TI CC2530 RF chip design nodes, Combining the soft and hardware to realize the network communication, RSSI value is extracted by programming via different grades of power, different distances measurement. The experimental results show that in different distance, the power loss is different, the measurement distance is small, the loss of value is low, contrary the higher. Finally fitting is obtained by the chart of distance-power prove that RSSI ranging technology based on CC2530 is a effective method for measuring in shorter distance.
