摘要：
为解决精密仪器的状态监控、桥梁的健康监测等问题,结合无线射频技术与fpga技术研制的无线数据采集系统,应用无线单片机nrf24e1实现了无线通信功能,与有线传输方式相比,无线传输方式可以避免信号传输线对现场操作的牵绊。应用fpga器件ep1c3t144c6实现了数据采集,性能大大优于传统的单片机控制数据采集系统。结果证明,该系统操作简单,工作稳定可靠,快速高效,具有广阔的应用前景。

abstract: in order to solve the problem of state control for precision instruments and safety monitoring of bridges, radio frequency technology and fpga technology were used to develop a wireless data acquisition system.compared with the transmission cable, using wireless single chip nrf24e1 to achieve a wireless communications fupctions avoid the signal transmission lines restrictions at operating site.fpga device ep1c3t144c6 was use to achieve a data acquisition, which is much better than traditional single-chip control data acquisition system.the results show that this system is simple, stable and reliable, fast and efficient and will be widely applied.
