As a new technology, long-term strain monitoring system of Large concrete structures has been applied to the management and maintenance of concrete structures in recent year.It has an important project value, wireless vibrating wire sensors have a strong anti-jamming, high precision, transmission distance and other characteristics, widely used in the vibration of massive concrete structures, stress and other dynamic physical monitoring. This paper discusses the wireless strain measurement system and the working principle of wireless vibrating wire sensors, designed the excitation of vibrating wire sensors circuit and the internal excitation frequency measurement circuits, and wireless communication module, then analyzed the characteristics of wireless vibrating wire sensors. Through the practical application, it shew that the designed wireless vibrating wire sensors with good performance.
