【摘要】：温度控制是混凝土固化期间的重要措施。针对现有混凝土温度监测方法的缺点,设计一种用于混凝土温度监测的无源射频识别(RFID)传感器标签。该RFID传感器标签是基于超高频(UHF)的EPC-2通信协议,且工作于无源模式下。由于混凝土是有损多相复合材料,文中具体分析电磁波在混凝土中的总损耗,确定标签可正常工作的基本条件。后期试验对所设计的温度传感器标签进行了温度测试、校准以及通信性能测试。试验结果表明,基于文中设计的无源RFID传感器标签所测试的温度与传统的热电偶测试结果基本一致,最大温差不超过0.5℃。相比于现有的混凝土温度监测方法,具有便利性强、成本低、寿命长等显著优点。
[Abstract]:Temperature control is an important measure during the curing period of concrete. In view of the shortcomings of existing methods of concrete temperature monitoring, a passive RFID (RFID) sensor tag for concrete temperature monitoring is designed. The RFID sensor tag is a EPC-2 communication protocol based on UHF (UHF) and works in passive mode. Because concrete is a lossy multiphase composite material, the total loss of electromagnetic wave in concrete is analyzed in detail, and the basic conditions under which the label can work normally are determined. The temperature test, calibration and communication performance test of the designed temperature sensor label were carried out in the later test. The experimental results show that the temperature measured by the passive RFID sensor tag designed in this paper is basically consistent with the traditional thermocouple test results, and the maximum temperature difference is less than 0.5 鈩，
