摘要
为了满足飞机发动机参数信号高速采集传输的需要,文中设计了一套针对多通道LVDS接口的高速数据接收传输系统。采用Kintex-7 FPGA芯片和光纤收发模块为核心架构,实现多路信号时分复用,基于Aurora光纤协议完成数据中间传输,最后使用TOE技术实现千兆以太网与上位机通信。测试结果表明,该系统最高数据传输速率能实现875 Mbps,并且具有较好的实时稳定可靠性。
In order to satisfy the need of high speed real-time acquisition and transmission of aircraft engine parameter signal,this paper designed a high-speed data receiving and transmitting system for multi-channel LVDS interface. The system used Kintex-7 FPGA chip and fiber transceiver module as the core architecture to achieve multi-channel signal multiplexing,and completed the data transmission based on Aurora optical fiber protocol. Finally,the system used the TOE technology to achieve Gigabit Ethernet for communicating with host computer. The experimental results indicate that the system can achieve the highest data transfer rate of 875 Mbps,and has good real-time stability and reliability.
