Spacecraft test power supply and distribution system health monitoring and processing method

Abstract

The invention discloses a spacecraft test power supply and distribution system health monitoring and processing method, and relates to the technical field of spacecraft test health monitoring; the method comprises the following steps of step 1, performing power supply under voltage early warning processing before power on of single unit equipment; step 2, performing under voltage fault alarm and automatic emergency treatment on a bus; step 3, carrying out over-charge pre-warning, fault alarming and automatic emergency treatment on a storage battery; step 4, carrying out over-discharge early warning, fault alarming and automatic emergency treatment on the storage battery; and step 5, carrying out PCU temperature fault alarm and automatic emergency treatment. By adoption of the method, problems of lack of power supply early warning before power-on of the load, weak automatic emergency treatment function and low monitoring coverage in spacecraft testing are solved.

Description

technical field [0001] The invention relates to the technical field of spacecraft test health monitoring, in particular to a health monitoring processing method of a spacecraft test power supply and distribution system. Background technique [0002] With the rapid development of my country's aerospace technology, the number of spacecraft under test is increasing year by year, but the test cycle is gradually shortening. With the increasing number of spacecraft testing tasks in the year, how to complete the spacecraft test safely, quickly and effectively is of great importance. The further development of aerospace industry is of great significance. In spacecraft testing, the healthy and stable operation of the power supply and distribution system is the basis of spacecraft testing. Once a power supply and distribution failure occurs, it will cause harm to single-machine equipment or even multiple subsystems. Therefore, research on spacecraft testing power supply and distributio...
