Automatic ground testing system of spaceborne electronic equipment

Abstract

Disclosed in the invention is an automatic ground testing system of spaceborne electronic equipment. The invention aims at providing an automatic ground testing system having advantages of high integration, reliability, and extensibility, high comprehensive degree, and good capability of reduction of equipment and interfaces. According to the technical scheme, tested equipment, an integrated exciter, and a response analyzer are connected by testing switch matrix equipment; and one end surface of the testing switch matrix equipment faces the integrated exciter or the response analyzer and the other end surface faces the tested equipment. Loading and measurement of different parameters are carried out by switching connectors at different positions of the testing switch matrix equipment. A main control computer carries out data interaction with the integrated exciter, the response analyzer, the testing switch matrix equipment, integrated power supply equipment, and an integrated monitor by a fiber LAN switched network; analysis and testing data are outputted in a report mode; and instructions and remote telemetering information of the integrated monitor, an integrated channel unit, an integrated service unit, and an integrated management and control unit are transmitted by the fiber LAN switched network.

Description

technical field [0001] The invention relates to a ground integrated test system for space-borne integrated electronic equipment. Background technique [0002] With the development of large aerospace vehicles, more stringent requirements are put forward for the integration, scalability and integration capabilities of on-board electronic systems. But so far, it is still impossible to maintain satellites in orbit. Due to these factors, a large number of tests must be carried out on the ground during the satellite development process to verify the correctness and reliability of its design. At the same time, the test is also to improve the design scheme and control the quality of the product. It is therefore an important tool in the design and production process throughout the entire research and manufacturing process. The development of satellites starts from pre-research, through design and production, until finalized test flight and flight test, and a lot of experimental wor...
