Ground equipment health status inspection method based on daisy chain topology

Abstract

The invention provides a daisy chain topology-based ground equipment health state inspection method, which solves the working state self-inspection problem of spacecraft comprehensive test equipment, can improve the ground equipment self-inspection efficiency, and realizes equipment autonomous health management in combination with an equipment health assessment method. The daisy chain topology-based ground equipment health state system-level self-checking method comprises the following steps: defining and dividing ground equipment into n nodes according to distributed nodes on a bus, the distributed nodes being node modules with mutually independent functions, adjacent nodes are divided into preorder nodes and postorder nodes according to communication position information on a bus and a communication connection relation between the node modules, and the preorder nodes and the postorder nodes form a daisy chain linear topological structure; and checking the health state of each node module item by item, and sequentially judging the health states of the node modules.

Description

technical field [0001] The invention belongs to the field of spacecraft ground testing, and relates to a method for checking the health status of ground equipment based on a daisy chain topology, which is suitable for checking the status of spacecraft ground equipment. Background technique [0002] The spacecraft comprehensive test equipment is an important part of the spacecraft comprehensive test. Whether the test equipment is in normal condition directly affects the effectiveness of the spacecraft test results. The abnormality of the test equipment will directly or indirectly cause potential impact on the spacecraft. Therefore, the development of It is very necessary to check the working condition of the test equipment. [0003] Existing test equipment lacks effective automatic inspection methods and effective alarm prompts, and mainly relies on manual measurement and multi-parameter comprehensive evaluation. This kind of status inspection method has the characteristics o...
