摘要
针对目前矿井事故出现后不能精确确定人员位置而导致不能及时救援的现状,设计了一种基于Zigbee的井下人员定位系统。介绍了系统的整体设计,详细阐述了以CC2431为核心的传感器节点和以CC2530为核心的路由器节点的硬件设计及其对应的软件设计,并结合基于RSSI的定位算法对矿井人员进行实时定位。通过实地的模拟实验可知,该系统的设计可实现定位精度在3 m之内。
The people who can＇t be rescued after the mine accidents occuring because it can＇t precisely determine their positions. In view of the situation, it designs a kind of underground personnel positioning system based on Zigbee. Introduces the overall design of the system. It elaborates hardware design which are the sensor node as the core of the CC2431 and the router node as the core the CC2530 and the corresponding software design, all of which are based on the combination of RSSI positioning algorithm to mine personnel positioning. Through the experiment, it shows that the design scheme of this system can realize the positioning accuracv in the range of 3 m
