摘要:
针对恶劣环境下压力信号精确测量和实时监测的迫切需求，该文基于LC谐振电路设计提出了一种高品质强耦合的无线无源压力传感器的优化设计，并针传感器的性能进行仿真优化分析。在matlab仿真分析了获得了用于设计高品质因数传感器电感线圈的对比参数后，对拥有不同参数LC谐振电路的传感器进行耦合仿真优化设计。仿真结果表明，为了使传感器具有较高的品质因数，传感器上的电感线圈不能过多，11圈为最佳，并且在电感线圈的线宽和线距加宽到0.5 mm，厚度增加到70 um时，传感器具有较强的信号传输能力和良好的稳定性。该文所研究的设计方法为实现高精度高稳定性的无线无源压力传感器的设计与研究提供了思路借鉴。
Abstract:
In view of the urgent need for accurate measurement and real-time monitoring of pressure signals in harsh environments, this paper proposes an optimal design of a high-quality strong-coupling wireless passive pressure sensor based on the design of LC resonant circuit, and conducts simulation optimization analysis based on the performance of the sensor. After the matlab simulation analysis obtained the comparative parameters used to design the high quality factor sensor inductance coil, the coupling simulation optimization design of the sensor with different parameters of the LC resonant circuit was carried out. The simulation results show that in order to make the sensor have a high quality factor, the inductance coil on the sensor should not be too many, 11 turns is the best, and when the line width and line spacing of the inductance coil are widened to 0.5mm and the thickness is increased to 70um , the sensor has strong signal transmission ability and good stability. The design method studied in this paper provides a reference for the design and research of wireless passive pressure sensor with high precision and high stability.
