摘要
传统的变电站巡检方式由于其固有缺陷越来越不能满足变电站管理信息化和规范化的要求,提出了一种基于声表面波RFID技术的变电站巡检系统;该系统采用移动或者固定RFID读写器作为巡检器,应用声表面波RFID技术、Wi-Fi无线通信技术,可以方便地记录电力设备的到位情况和缺陷信息,解决了传统巡线方案中存在的人员到位困难和巡检数据不及时等问题;详细介绍了无源无线声表面波RFID技术,得到一种新型适应性强的RFID读写器的设计方案;这种读写器通过调节自身参数即可实现工作频率可调与工作协议可变,从而实现读取处于不同频率与基于各种通信协议的电子标签;实验结果表明该新型变电站巡检方式具有优异的表现,具有较广的应用前景。
The traditional inspection methods of the substation cannot meet the substation information management and standardization requirements because of its inherent defects. Substation inspection system based on the SAW--RFID technology is proposed. The system uses a mobile or fixed SAW--RFID reader as the inspection device, the application of SAW RFID technology. By using the Wi--Fi wireless communications, the SAW--RFID and the Zigbee technologies, the new inspection system can easily record the place and defects in the elec- trical equipment. The wireless passive SAW RFID technology, adjustable frequency reader design and implementation are also studied. A new frequency adaptive RFID reader is designed. This reader can read in different frequencies with the electronic tag based on a variety of communication protocols by adjusting its own parameters to the operating frequency. The experimental results show that the new substation inspection method has excellent performance.
