Abstract

Abstract:

The ultra wideband location has the advantages of low power consumption,high speed transmission and high security level,especially it can support high location accuracy.It plays an irreplaceable role in the information construction of pumped storage power station.The ultra wideband positioning technology was introduced.The positioning technologies such as RFID,ZigBee,high-frequency pulse were compared and analyzed.The system architecture and positioning principle were described.Finally,the application of the pumped storage power station were introduced.

Key words: UWB, pumped storage power station, personnel location’s management system

技术方式	技术原理	频率	基站半径	定位精度	技术特点
RFID	RSSI	2.4 GHz	全向最大80 m，定向最大150 m	>1 m，通过辅助定位器可实现	RFID 为私有通信协议，定制性强、安全性高，可根据用户的应用灵活开发，属于ISM开放频段，专用于物联网
ZigBee		2.4 GHz	全向最大80 m，定向最大150 m	>1 m，通过辅助定位器可实现	国外标准协议，成熟、兼容性强，但由于公有协议存在安全漏洞，容易被破解。ZigBee具有自组网能力（带宽2 Mbit/s可用于读表），但在定位中此功能往往会成为缺陷，基站节点瘫痪造成定位的瘫痪
高频脉冲	UWB	6.24～6.74 GHz	35～50 m	10 cm（无需辅助定位器）	精度高，频段需要无线电委员会批准，干扰少，标签电池续航时间短
