Abstract

The invention provides a triple modular redundancy control and data management computer and a using method thereof which are highly reliable. The computer comprises a power supply module, a solid storage module, a voting control module, an interface control module and three processor modules. The power supply module comprises three power supply units supplying power for three processors respectively so as to supply power for the solid storage module, the voting control module and the interface control module; the solid storage module comprises three solid data storage units, and the signal communication is implemented between the three solid data storage units and the three processors and between the three solid data storage units and a ground test and control communicator; the voting control module comprises three voting control units, and the signal communication is implemented between each voting control unit and the three processor modules; the output interface of the voting control module comprises a 1553B bus output interface, an OC gate output interface and a RS422 communicating output interface.

Description

technical field [0001] The invention relates to the technical field of computer architecture, in particular to a highly reliable computer architecture that resists spatial transient errors. Background technique [0002] With the requirements of some space applications, the multi-satellite upper stage is used to realize the carrying task of the satellite. The upper stage control and data management computer takes into account the typical characteristics of the rocket-borne computer and the space-borne computer. The upper-level control and data management computer should not only have the characteristics of high real-time performance and low cost of the rocket-borne computer, but also have the characteristics of the space-borne computer's ability to resist space transient errors and manage tasks autonomously. [0003] The existing on-board computer has a redundant system architecture of active and standby, with many working modes, requiring long-term operation on-orbit, high r...
