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.
