Description

technical field [0001] The invention relates to a wireless multi-channel vibrating wire acquisition instrument and an acquisition method thereof, which are applied to the structural safety and health monitoring industry. Background technique [0002] The vibrating wire sensor is a non-electrical measurement sensor that is widely valued and widely used at home and abroad. Because the vibrating wire sensor directly outputs the natural vibration frequency signal of the vibrating wire, it has the characteristics of strong anti-interference ability, small influence of electric parameters, small zero drift, small influence of temperature, stable and reliable performance, vibration resistance, and long life. Vibrating wire sensors have been widely used in long-term monitoring projects in engineering and scientific research. The vibrating wire collector is an instrument used to collect vibrating wire sensors. At present, the multi-channel vibrating wire collector used in engineer...
