Optimal configuration method for test resources of spacecraft

Abstract

The invention provides an optimal configuration method for test resources of a spacecraft. The method comprises the following steps: 1, utilizing a method of weighted assignment to primarily determine testing sets of a product; 2, designing a multi-single model of the product and generating matrices related to tests of the product; 3, verifying whether test sets can satisfy the requirements for fault monitoring and diagnoses or not, adjusting value affecting factors in the method of weighted assignment if the test sets do not satisfy the requirements and repeating steps 2 and 3 till the requirements can be net; 4, designing an optimal target for test resources; 5, utilizing an optimal distribution method for optimal configuration of test resources; 6, verifying whether optimized test resources can satisfy the requirements for fault monitoring and diagnoses or not, taking an optimal test set as a complete test set of the product if the optimized test resources can satisfy the requirements for fault monitoring and diagnoses, or otherwise repeating steps 5 and 6 till the complete test set is obtained. The optimal configuration method for test resources of the spacecraft has the following beneficial effects: the engineering experience and theory guidance are integrated so that the repeated design during production realization is avoided and waste of test resources is avoided.

Description

technical field [0001] The invention relates to a method for optimal configuration of spacecraft testing resources, which is used for testing design of spacecraft and belongs to the field of spacecraft testing. Background technique [0002] With the enlargement of spacecraft and the complexity of its structure and functions, the problems of testing and diagnosis have become increasingly prominent, and the testing methods have gradually developed from early manual testing equipment or simple special testing equipment to large-scale automatic testing equipment (Automated Test Equipment, ATE). , and can design a built-in test (Built-in Test, BIT) in the spacecraft according to the requirements to realize the online fault self-test and self-diagnosis of the spacecraft, which is conducive to reducing the requirements for the technical level of testers, improving system availability, reducing Usage and maintenance costs have a positive effect. However, BIT equipment (Built-in Tes...
