基于Zigbee无线定位及瓦斯浓度测量系统设计

摘要

In this paper, the colliery monitor system of Wireless Sensor Network （WSN） based on RFID and ZigBee technology is proposed in order to monitoring gas and worker underground with wireless RF technology. By researching to the arithmetic of wireless router and the mobility of self-built Zigbee network based on IEEE802. 15.4, the integrated wired/wireless networking system for coal mine safety can be set up, which achieve long distance information transmission and proceed the data by exchanging information with the data center ground. The system can achieve the wireless information exchage between RFID label - RFID card reader-ZigBee notes-ZigBee coordinator. The systems have low power, low cost, more fitable, more importance for coal mine safety.%开发了一种基于RFID和ZigBee技术的无线定位及瓦斯浓度测量系统，运用无线射频识别技术，实现对矿井人员信息的近距离识别；在ZigBee协议研究基础之上，通过对无线路由算法和自组网络灵活性的研究，实现煤矿安全系统的有线网络和无线网络的集成，实现信息远距离传输，并利用地面中心数据库实现信息的处理，实现了“RFID标签-RFID读卡器-zigbee节点-zigbee网络主节点”的无线信息传递。
