Wide-range dynamic scan high-precision fiber Bragg grating sensor demodulation instrument could effectively improve the measuring range of the optical fiber grating sensors. Ethernet communication module is an extremely important part of the high -precision grating sensing demodulation devices. Network interface based on Ethernet control chip DM9000A is used to send and receive grating sensing information. The network transformer YL18-2050S is used to convert and filtering the pulse from network. The transmission and receiving program of grating demodulation data, hardware circuit of Ethernet transmission interface are designed. The network interface is able to achieve high speed;the accurate and real-time transmission of the grating sensing information has been demonstrated experimentally.
