Satellite-borne high-resolution imaging data transmission and acquisition system

Abstract

The invention relates to a satellite-borne high-resolution imaging data transmission and acquisition system. The system comprises a data source, a data protocol conversion plate and a data acquisitionand storage device, wherein the data source comprises an output interface connector and a satellite-borne high-resolution imaging device which takes TLK2711 transmission chips as output interfaces; the data protocol conversion plate comprises an input interface connector and a conversion circuit; the data acquisition and storage device comprises a storage computer and Camera-Link to PCI-e image acquisition cards in one-to-one correspondence with the output interfaces; the data transmission protocol conversion plate completes conversion from TLK2711 data transmission interfaces to Camera-Linkimage data transmission interfaces; and the data source is connected with the data acquisition and storage device through the data transmission protocol conversion plate. According to the system, theproblem that common image acquisition and storage systems are seriously lack of throughput capacity and cannot satisfy the real-time data acquisition and storage of high-resolution images is solved.

Description

technical field [0001] The invention belongs to a high-resolution interference imaging spectrometer image data transmission and collection ground verification system, and relates to the field of high-speed data transmission and collection. Background technique [0002] With the development of my country's space remote sensing technology, satellite remote sensing is increasingly showing the development trend of high temporal resolution, high spatial resolution and high spectral resolution, the types of payload data are becoming more and more diverse, and the amount of data is increasing. As a result, the data rate and bandwidth are getting higher and higher. Data transmission is also gradually transitioning from the traditional multi-channel LVDS parallel transmission interface to a higher bandwidth and higher reliability interface. For example, in recent years, the application of high-speed serial / deserialization transceiver TLK2711 in spaceborne high-speed, large data load ...
