摘　　要：针对弹载数据记录设备和地面测试设备之间大量数据高速传输的问题,本文提出了应用低电压差分信号(LVDS)接口器件和FPGA结合的设计方案实现数据高速远距离传输。详细介绍了LVDS的基本工作原理,并对该装置软硬件设计以及各个模块功能的具体实现进行讨论和分析。该装置已成功应用某项目中,具有较高的可靠性、通用性。In allusion to the solution of high-speed transmission of large amounts of data between the data re- cording equipment in guided missile and ground test equipment, the project is proposed. The design is a combined application of low-voltage differential signaling （LVDS） interface device and FPGA to achieve high-speed long-dis- tance data transmission. The basic working principle of the LVDS in detail is described, and maken a discussion and analysis for the concrete realization of hardware and software design of the device and each module features. The device is successfully applied to a project, with high reliability and versatility.
