光纤陀螺惯导系统的以太网接口设计

Design of ethernet interface of the fiber optic gyroscope inertial navigation system

针对光纤陀螺惯导系统导航信息在对数据传输大量性、实时性方面的要求,采用基于FPGA和DM9000的以太网接口形式传输数据。为FPGA配置以太网接口,与外部网络实现通信。在PC端将导航数据信息显示于动态网页上,进行系统的动态监测。系统各个部分收发数据的测试验证了其功能的有效性,实现了光纤陀螺惯导系统导航信息的以太网传输及实时监控功能。

Aiming at the requirement for the large quantity and the real-time performance during the transmis- sion of the fiber-optic gyroscope INS （Inertial Navigation System, INS） data, the paper proposed the ethernet interface form based on the FPGA and DM9000. The ethernet interface configured to the FPGA communicates with the external network. On PC, the navigation information will be displayed on the webpage. After testing and verifying the validity of the function of each part of the system. The ethernet transmission and the re- al-time monitoring of the SINS information are achieved finally.
