Implementation of frequency measuring method based on vibrating wire sensor

A frequency measuring method is designed based on the principle of vibrating wire sensors, the design principle is introduced in detailed, and the design ideal of measuring frequency system, the hardware of circuit, work-principle,flow of the software is expatiated. The experiment result indicates that the resolution is 0.01 Hz by taking this method, the difference between it and XPO2 type frequency measuring device is lower 2 Hz. This circuit has many characters such as design thoughts clear, simply hardware circuit, credible stimulation oscillation, controllable stimulation oscillation, higher signal sensitivity, easy to operate, numeric display, inexpensive, fast and continuous detect, and so on, and has better application foreground.
