基于振弦传感器的应变无线测量系统设计

针对传统振弦式应变测量手段的缺点与不足，设计了一种基于振弦式传感器的应变无线测量系统。整个系统通过ARM来控制，并通过通用分组无线业务（ GPRS）网络组成无线通信网络，实现了完全无人值守测量和系统的远程控制以及数据的无线传输。系统采样太阳能供电，可以更好地适应现场和野外试验不方便布线和取电的场合；系统具有大容量数据存储能力，无线传输数据的能力，具有高可靠性、高精度、适应性强、低成本等诸多优点，该测量系统使用方便，功能强大，智能化，必将有良好的应用前景。

Design of a wireless strain measurement system based on vibrating wire sensor

Aiming at shortage of traditional vibrating wire strain measurement method,a wireless strain measurement system based on vibrating wire sensors is designed. The whole system is controlled by ARM,and wireless communication network is built up through GPRS network,so a completely unattended measurement,and remote control of system together with wireless transmission of datas can be realized;the system power supply uses solar power so it can easily adapt to occasions which are inconvenient for electric wiring and power supply in field measurement. The system has high-capacity of data storage and is capable of wireless transmission of data,and has high-reliability,high-precision,strong-adaptability,and low-cost,and this measurement system is bound to have a good application prospect for its convenient usage,powerful function and intelligence.
