基于LVDS的固态存储器与地面综合测试台通信系统设计

Communication System Between Data Memory and Integrated Test Platform Design Based on LVDS

针对遥测系统远程数据传输过程中出现的由于干扰引起的误操作以及数据紊乱问题,提出了一种基于LVDS的具有高可靠性的通信系统解决方案;系统以FPGA为控制核心,采用LVDS高速数据传输技术,实现飞行器遥测数据存储系统与地面设备的通信;为保证数据链路与命令控制链路的准确性和可靠性,设计了一套完整的通信协议;经大量试验表明,该通信系统性能稳定、数据及命令传输可靠,现已应用于某航天遥测数据通信系统。

For the problems of data disorder and misoperation caused by interference during the telemetry system remote data transmis- sion, a kind of LVDS communication system with high reliability has been put forward. To achieve the communication between telemetry da- ta storage system and aircraft ground equipment, it takes FPGA as the control core and use LVDS high--speed data transmission technology in the system. In order to ensure the accuracy and reliability of the data link and command control link, a set of complete communication pro- tocol has been designed. Experiments show that, the communication system performance is stable and reliable in the terms of data and com- mand transmission, the system has been applied to a remote data communication system.
