星载光谱仪的数据接口为LVDS接口,为快速地将其转换为地面民用设备,设计了LVDS转千兆以太网适配器.适配器采用FPGA为主控芯片,接收光谱仪发送的串行的图像数据,并将其封装为以太网帧格式,然后通过网口芯片传输给上位机;同时适配器接收上位机发送的命令数据,并转发给光谱仪.实验结果表明,适配器在传输速率为43 Mbit/s时,连续运行48 h,误码率为0,在实验室条件和自然条件下均能稳定传输数据,可作为光谱仪的转换接口.“,”Satellite-borne spectrometers use LVDS interface,in order to transform them into industrial equipments, a LVDS to Gigabit Ethernet adapter was designed. The adapter uses FPGA as its main control chip,it receives serial image data sending from spectrometers, and encapsulates them into Ethernet frame formet, then transmits them to upper monitor through Ethernet chips;at the same time,the adapter receives commands from the upper monitor,and transmits them to the spectrometer. The test result shows that after running 48 hours at the rate of 43 Mbit/s,the bit error ratio of the adapter is 0,it can can transmit data steadily in both laboratory condition and natural condition,and can be used for interface conversion for spectrometers.
