Abstract: In order to solve the problems of precision instrument status monitoring and bridge health monitoring, a wireless data acquisition system was developed by combining wireless radio frequency technology with FPGA technology. The wireless microcontroller nRF24E1 was used to realize the wireless communication function. Compared with the wired transmission method, the wireless transmission method can avoid the signal transmission line from hindering the on-site operation. The FPGA device EP1C3T144C6 was used to realize data acquisition, and its performance was much better than the traditional single-chip microcomputer controlled data acquisition system. The results show that the system is simple to operate, stable and reliable, fast and efficient, and has broad application prospects. [Author Abstract]
