| Abstract: | Aiming at problem that frequency measurement system of vibrating wire sensor is easily affected by noise,resulting in decreased precision of frequency measurement,introduce a high precision frequency measurement method based on M-Rife algorithm. Combined with the hardware structural characteristics and programming mode of ARM processor,the M-Rife algorithm is transplanted to ARM processor,and high precision frequency measurement system of vibrating wire sensor is realized. Experimental results show that the relative error of frequency measurement of system is less than 0. 025%,and the system has strong anti-interference ability. |
