Satellite-borne integrated mass data storage and playback equipment

Abstract

The invention discloses satellite-borne integrated mass data storage and playback equipment. An integrated data interface module carries out time attitude data and control information interaction on an integrated data management computer through a frequency scale signal connector and an optical fiber Ethernet connector, and carries out integrated data transmission on an image sensor through an optical fiber integrated data connector; under the control of a unified protocol, the image sensor, a microwave aperture and a loading data source are subjected to integrated preprocessing and storage; an integrated storage control module carries out control, fault monitoring and dynamic refreshing on a startup and shutdown OC (Objective-C) instruction of storage equipment; a high-capacity data storage module receives a control instruction sent from the integrated storage control module through FPGA (Field Programmable Gate Array), reports health, state and fault information to the integrated storage control module, receives integrated data from the integrated data interface module through a high-speed interface unit, realizes ECC (Error Correction Code) coding and decoding, a balancing algorithm and bad block rejection through a data preprocessing unit, and stores the data into a solid-state memory array.

Description

technical field [0001] The invention relates to a space-borne integrated massive data storage and playback device, which belongs to the field of space-borne data collection and storage. Background technique [0002] Due to the limited land resources of our country, it is difficult to set up a large number of ground receiving stations abroad. The data of satellites abroad can only be stored on the satellite, and the data will be played back when the satellite transits. This urgently needs a large capacity, fast access speed, Spaceborne data storage devices with small size and low power consumption; and because aerospace storage devices are related to whether space exploration or on-orbit test data can be completely preserved and reliably reach the hands of ground test personnel, and then determine the completion of space science tasks, Therefore, the onboard storage system is an important part of the electronic system of the spaceflight platform, and its performance is relate...
