Abstract

The floating complementary split-ring resonator (FCSRR) is presented in this letter. Because of its unique resonant mode, the FCSRR is suitable for the perception of rotational motion. The amplitude of the resonant signal changes as the motor rotor drives the rotation of the FCSRR at 3.34 GHz, which produces an amplitude-modulated signal. Then, the rotation period is double of envelope period. A rotational speed measurement system with FCSRR is investigated based on the above principle. The signal processing circuit of the system converts the microwave envelope signal into digital pulses to sense rotational speed. The test results indicate that the measurement resolution of this system is 0.5 r/s with an average error of 0.44% compared to a commercial speedometer. This system can be used as an alternative to a laser tachometer when ambient visibility is low.
一种基于浮式互补分环谐振器的转速测量系统
本文介绍了一种浮动互补裂环谐振器(FCSRR)。由于其独特的谐振模式,FCSRR适合于旋转运动的感知。当电机转子驱动FCSRR在3.34 GHz处旋转时,谐振信号的幅值发生变化,产生调幅信号。则旋转周期为包络周期的两倍。基于上述原理,对FCSRR转速测量系统进行了研究。该系统的信号处理电路将微波包络信号转换成数字脉冲信号来检测转速。测试结果表明,与商用速度计相比,该系统的测量分辨率为0.5 r/s,平均误差为0.44%。当环境能见度较低时,该系统可作为激光转速计的替代方案。
