High-speed integral satellite-borne data management system

Abstract

The invention provides a high-speed integral satellite-borne data management system, which comprises load data receiving channels, real-time data receiving channels, storage region managing units, storage arrays, multiple connection frame combination units, a channel multiple connection unit and a channel coding unit, wherein the load data receiving channels are used for receiving load data sent by a loading machine, the real-time data receiving channels are used for receiving real-time telemeasuring data sent by a satellite platform, the storage region managing units are connected with the load data receiving channels, and are used for distributing storage spaces with different address sections to different load data for storing, the storage arrays are connected with the storage region managing units, and are used for storing the load data, the multiple connection frame combination units are connected with the storage region managing units in a corresponding manner, and are used for carrying out combination and multiple connection on the load data read from the storage arrays, so as to form multiple connection frames, the channel multiple connection unit is used for carrying out multiple connection on the multiple connection frames and the real-time telemeasuring data, so as to form data transmission frames, the channel coding unit is used for carrying out coding processing on the data transmission frames, and sending the coded data through a data transmission / telemetering launching integral machine. The high-speed integral satellite-borne data management system provided by the invention solves the problems of volume, power consumption, quality and cost of the satellite-borne data management system.

Description

technical field [0001] The invention relates to the field of satellite data management, in particular to a high-speed integrated satellite-borne data management system. Background technique [0002] For satellites, the data management system occupies an important position in the entire satellite electronic system, which is directly related to the success or failure of satellite missions. The current mainstream satellite data management system adopts the design architecture of "multiplexer + memory", and the satellite data management system is designed into two separate modules. Satellite data management systems designed with such an architecture are generally used for larger satellites; for micro-nano satellites, this architecture has obvious disadvantages, such as large system volume, high quality, high power consumption, and high cost. It is not suitable for micro-nano satellites that are sensitive to power consumption, cost, volume, and quality. Contents of the inventi...
