摘要
本文设计的数据转发装置是某型号飞行器图像采集装置的一部分,数据转发装置以FPGA作为主要控制核心,W5300作为主要接口芯片,搭建了以太网接口模块、USB通信模块以及电源管理模块,主要实现了为可见光采集设备供电并将采集到的图像数据经过编帧打包后传输至上位机或数据存储装置的功能。实验结果表明,该数据转发装置供电可靠、数据传输速率可达4 Mbps,性能稳定,现已广泛应用于飞行器的飞行试验中。
The data forwarding device designed in this paper is a part of an aircraft image acquisition device.The data forwarding device takes FPGA as the main control core and W5300 as the main interface chip to build Ethernet interface module,USB communication mod-ule and power management module.It mainly realizes the function of supplying power to the visible light acquisition equipment and transmitting the collected image data to the host computer or data storage device after framing and packaging.The experimental results show that the data forwarding device has reliable power supply,data transmission rate of 4 Mbps and stable performance.It has been widely used in aircraft flight test.
