Embodiment Construction

[0057] A power supply and distribution joint test verification system based on an integrated electronic system is composed of on-board equipment and ground equipment.

[0058] The on-board equipment includes:

[0059] The star management unit is used to control the operation of the battery pack, the battery pack interface management unit and the power controller;

[0060] The power controller is used to stably adjust the main bus voltage to the bus voltage, complete the charge and discharge control of the battery pack and the shunt regulation of the solar array simulator, and measure the temperature of the battery pack;

[0061] The battery pack interface management unit completes the voltage collection of the battery pack, and sends the collected voltage signal to the star management unit;

[0062] The ground equipment includes:

[0063] The solar array simulator, connected with the power controller, is used to simulate the satellite solar wing array;

[0064] The centrali...

Abstract

The invention discloses a comprehensive electronic system-based power supply and distribution joint test verification system and a method and belongs to the technical field of space. With the joint test verification system built, a comprehensive electronic subsystem and the software and hardware of a power supply and distribution subsystem are unified; the single machine-bus communication function, hardware interface and single-machine function of the power supply and distribution subsystem can be verified under the comprehensive electronic system, and the software and hardware functions of the power supply and distribution subsystem can be verified comprehensively. Different working modes are set in the power supply and distribution subsystem; the functions and performance of the subsystem under the different working modes are verified through the joint test verification system; mode combinations under different working conditions are set, so that the functions and performance of thesubsystem in a mode switching process can be verified; and the joint test verification problem of the power supply and distribution subsystem under the comprehensive electronic system is solved.

Description

technical field [0001] The invention relates to a power supply and distribution joint test verification system and method based on an integrated electronic system, belonging to the field of space technology. Background technique [0002] As the key subsystem of the whole star, the power supply and distribution subsystem is related to the safety of the whole star. Before the subsystem goes to the satellite, it is necessary to fully verify the interface matching and functional performance of the subsystem. Ensure that each hardware stand-alone function of the sub-system is normal, the interface is matched correctly, and the logic function of the system software is correct. [0003] Under the integrated electronic system, the energy management software in the star processing unit realizes the battery charging and discharging management and fault switching functions of the subsystems. [0004] The power supply and distribution subsystem includes two parts: power supply and pow...
