Abstract

The invention provides a comprehensive management system for a platform and load integrated satellite and relates to the technical field of aerospace aviation. The problems that the resource use rate is low and extendibility can not be achieved due to the fact that a distributed type satellite-borne computer design method is adopted in an existing satellite electronic system are solved. The comprehensive management system for the platform and load integrated satellite comprises an integrated comprehensive control unit and a standard function extension unit. The standard function extension unit is interconnected with the integrated comprehensive control unit through an external CAN bus. The integrated comprehensive control unit is composed of a comprehensive management module, a communication interface module, a secondary power source and an arbitration logic control module. The standard function extension unit comprises an order control panel, an active temperature control panel and a mechanism control panel. According to the comprehensive management system, resources are integrated, the number of single machines and elements is reduced, orders are integrated, the order types and forwarding links are reduced, telemetering is integrated, redundant telemetering is reduced so that the bandwidth can be increased, functions are integrated, test links and test procedures are reduced, performance is integrated, and the size, the weight and power consumption of equipment are reduced.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to a comprehensive management system for platform-load integrated satellites, which can realize the integration and high integration of high-performance small satellite platforms and payload electronic systems, and simultaneously take into account the modularization and standardized functions of different types of small satellites Expand task requirements. Background technique [0002] With the continuous advancement of aerospace electronic technology and computer technology, the integration of modern small satellite electronic systems is getting higher and higher, which requires satellite electronic systems to have higher processing speed and more functions. The traditional satellite electronic system adopts a function-centric distributed design method, that is, various functions are assigned to the on-board computer of each subsystem such as the satellite management computer, t...
