摘　　要：根据目前变电站、电厂传统巡检方式存在的弊端,提出了一种可以实时定位人员位置,并根据不同位置提供多种服务的解决方案。比较了国内外多种定位系统,并总结了基于无源超高频电子标签定位的优势。系统根据物联网网络层次划分为感知层、网络层、应用层3层,分别阐述了感知层无源超高频电子标签的安置方案,网络层手持终端预处理感知对象数据,完成本地服务并将人员空间位置信息实时通过无线网络传递到应用层位置服务器,可以与厂站监控系统、智能变电站全景数据平台之间实现数据共享和智能联动。系统已实际应用于500kV智能变电站低压开关柜室和水电站廊道中,显著提高了人身安全性和厂站自动化水平。This paper proposes a solution for avoiding the disadvantages of the current patrol inspection system for power plant and substation, which can locate real-time the operators and offer different location based services. A variety of location systems at home and abroad are compared, and the advantages of the location system based on ultra-high frequency-radio frequency identification （UHF-RFID） passive tags are summarized. According to the network layers of the internet of things, the system is divided into three layers, namely, the perception layer, network layer, and application layer. Full account is given of the way the UHF-RFID passive tags are arranged in the sensor layer, preprocessing of the data in the portable terminal prior to rendering location based services, eventually transferring the acquired data to the interaction layer for sharing and cooperating smartly with the platform of panoramic data or the monitoring system. This method is successfully being applied to the low-voltage switehgear in a 500 kV smart substation project and the corridor in a hydropower station, which has improved personal security and the station automation level.
