摘要
文章分析了基于RSSI测距的WSN网络定位技术,以ti CC2530芯片为核心设计定位节点,实现了一套适用于各类室内密闭环境的WSN定位网络。针对RSSI测距精度有限、易受环境干扰的问题,文章设计了一套测距模型参数校准流程,用以降低RSSI测距误差,提高系统定位精度,并开发了上位机操作程序,便于用户实时监测网络运行情况。
This paper analyzes the WSN network positioning technology based on RSSI ranging, designs the circuit of WSN nodes with ti CC2530 soc, and establishes WSN positioning network designed for different kinds of indoor enclosed environment, in order to improve the accuracy of RSSI ranging and reduce the interference of environment factors, this paper designs a set of distance parameter calibration process to reduce the RSSI ranging error and achieve better accuracy of the positioning system. Finally a monitoring software for WSN positioning network is developed which is convenient for users to implement the data acquisition and network management.
