  • Novel Concrete Temperature Monitoring Method Based on an Embedded Passive RFID Sensor Tag.
    Sensors, 2017
    Co-Authors: Fangming Deng, Yigang He, Zhen Liang, Bing Li, Shuangxi Zhou
    Abstract:

    This paper firstly introduces the importance of Temperature control in Concrete measurement, then a passive radio frequency identification (RFID) sensor tag embedded for Concrete Temperature monitoring is presented. In order to reduce the influences of Concrete electromagnetic parameters during the drying process, a T-type antenna is proposed to measure the Concrete Temperature at the required depth. The proposed RFID sensor tag is based on the EPC generation-2 ultra-high frequency (UHF) communication protocol and operates in passive mode. The Temperature sensor can convert the sensor signals to corresponding digital signals without an external reference clock due to the adoption of phase-locked loop (PLL)-based architecture. Laboratory experimentation and on-site testing demonstrate that our sensor tag embedded in Concrete can provide reliable communication performance in passive mode. The maximum communicating distance between reader and tag is 7 m at the operating frequency of 915 MHz and the tested results show high consistency with the results tested by a thermocouple.

  • A Passive RFID Sensor Tag for Intelligent Concrete Temperature Control
    Proceedings of the 4th International Conference on Mechatronics Materials Chemistry and Computer Engineering 2015, 2015
    Co-Authors: Zhongbin Chen, Fangming Deng, Xiang Wu
    Abstract:

    This paper presents an integrated passive sensor tag for intelligent Concrete Temperature control. The sensor tag is based on EPC Generation-2 UHF communication protocol and operates in passive node. Except the antenna and matching network, the other blocks including RF/analog frontend, digital baseband, electrically erasable programmable read-only memory (EEPROM) and sensors, are fabricated in a single chip for low-cost application, from the test result we can see that this sensor tag can offer a believable measuring result.

  • Concrete Temperature monitoring using passive wireless surface acoustic wave sensor system
    Sensors and Actuators A: Physical, 2015
    Co-Authors: Jinyoung Kim, Rodriguez Luis, Marshall S. Smith, Julio Alberto Landero Figueroa, Donald C. Malocha, Boo Hyun Nam
    Abstract:

    In this paper, a novel nondestructive method for detecting Temperature variations of Concrete using a passive wireless surface acoustic wave (SAW) sensor system is described. Performance of the SAW orthogonal frequency coded (OFC) Temperature sensors was evaluated in air, liquid, and Concrete. To verify the response of the SAW sensor, Temperature was also measured using commercially available thermocouples and compared with the extracted Temperature in all environmental conditions. Analysis of the measured data showed that the SAW Temperature sensor system was successful in detecting Temperature over a wide range in all tested conditions with a high degree of accuracy and short interrogation time. When the sensors were embedded within a 2-in. thick Concrete cover, the maximum read distance was approximately 4 m.
