摘　　要：基于动态扫描的高精度宽量程光纤光栅传感解调仪,能够有效提高光纤光栅传感器的测量范围,以太网通信是高精度光栅传感解调仪中极其重要的环节。利用基于以太网控制芯片DM9000A的网络接口实现对光栅传感信息在以太网和计算机之间的发送和接收。利用网络变压器YL18-2050S来实现对网络上的脉冲进行转换和滤波的功能。完成了以太网数据的发送和接收程序和以太网传输接口的硬件设计。该网络接口能够实现光栅传感信息的高速、准确实时传输。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 receiying program of grating demodulation data, hardware circuit of Ethernet ~ransmission 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.
