Abstract

The invention discloses a triple modular redundancy based satellite-borne comprehensive electronic system used for data processing and data storage of a pico-satellite. The triple modular redundancy based satellite-borne comprehensive electronic system comprises a data processing module, a data memory module, an interface extension module and a power supply module, wherein the data processing module is connected with the interface extension module, and is connected with the data memory module; and the output of the power supply module is respectively connected with the input of the data processing module and the input of the data memory module. The data processing module fuses the principle of triple modular redundancy, so as to have high reliability, and avoid influence due to random errors to a certain extent; the data memory module adopts a cache and main memory combined manner, so as to realize high-capacity and long-life targets of a memory module based on the low cost; and the virtue DMA (direct memory access) principle is fused between the data processing module and the interface extension module, so as to simply and effectively solve the problem that the processing capability of the data processing module is wasted because the speed of an external interface of the data processing module is faster than that of an extension interface.

Description

technical field [0001] The invention relates to an integrated electronic system for pico-satellites, in particular to an integrated electronic system for data processing and data storage of pico-satellites. Background technique [0002] Picosatellites are tiny satellites weighing in the kilogram range. Compared with large satellites, it has the advantages of low cost, short manufacturing and launch cycle, and quick emergency response. [0003] The integrated electronic system is the data and command hub of the pico-satellite. It mainly undertakes important tasks such as data processing, data storage, data transmission, command sending and receiving and response of the pico-satellite. It is an important part of the pico-satellite. Its performance and reliability are very high To a certain extent, it represents the performance and reliability of the entire pico-satellite. [0004] The invention patent application with the publication number 102624439A discloses a multi-funct...
