遥感相机一般使用TLK2711接口输出图像数据,地面测试设备不能直接对其采集存储。文中设计了一种多通道遥感图像高速光纤传输系统,可对相机输出的TLK2711图像数据进行采集与缓存,并通过光纤接口传输给存储设备。实现了遥感相机与地面存储设备之间的高速图像数据通信,解决了现有地检存储设备不能直接进行数据通信的问题。系统设计了多通道TLK2711图像采集模块,多路图像数据分时复用处理模块,基于Aurora64B/66B传输协议光纤传输模块等,使相机图像数据稳定可靠地传给地面存储。经过实验测试,系统图像数据采集准确,数据传输无误码。系统效率高,稳定可靠,满足实际使用需求。

Remote sensing cameras usually use TLK2711 interface to output image data,which cannot be directly collected and stored by ground test equipment.A multi-channel remote sensing image high-speed optical fiber transmission system was designed,which can collect and cache the TLK2711 image data output by the camera,and transmit it to the storage device through the optical fiber interface.The high-speed image data communication between the remote sensing camera and the ground storage device was realized,which solved the problem that the existing ground inspection storage device cannot directly communicate data.The multi-channel TLK2711 image acquisition module,the multi-channel image data time-sharing multiplexing processing module,and the optical fiber transmission module based on the Aurora64B/66B transmission protocol were designed to make the camera image data stably and reliably transmitted to the ground for storage.After experimental testing,the system image data collection is accurate,and the data transmission is error-free.The system has high efficiency,stability and reliability,and meets the actual use needs.
