基于Zigbee协议的井下人员定位系统设计
首发时间:2011-12-15
摘要:矿井人员定位系统对于矿井的安全生产保障工作有着重大的意义,基于Zigbee协议的井下人员定位系统由服务器、协调器、定位基站和人员识别卡组成,根据矿井的环境,通过建立网状或者线状的无线网络,通过测量RSSI定位数据包的方式,能够实现井下人员的实时定位功能。通过精确测定矿井所在环境的信号传播模型以及灵活调节参与定位的基站的数目,能够提高定位给的有效性及可靠性。测试结果反复表明,定位误差通常能够控制在2.5m以内,能够较为准确地反应人员的分布状况。

Design of Positioning System for Mine Based on Zigbee Specification
Abstract:Positioning system is significant for mine safety protection work. The underground personnel positioning system based on the Zigbee protocol consists of servers, coordination, the base station and staff identification card, according to the mine environment, through the establishment of mesh or linear wireless net-works, by measuring the RSSI of the packets to achieve real-time positioning. Through accurately measuring the signal propagation model of the environment, and flexible adjustment in the number of base stations, the effectiveness and reliability of positioning system improve greatly. Repeated test results showed that position-ing error can usually control to 2.5m or less, performing well to reflect the distribution of personnel.
