摘要
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.
Abstract
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 de-signed,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 da-ta.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 col-lection is accurate,and the data transmission is error-free.The system has high efficiency,stability and reliability,and meets the actual use needs.
