Automatic joint test method for primary power supply subsystem of high-orbit communication satellite

Abstract

The invention relates to an automatic joint test method for a primary power supply subsystem of a high-orbit communication satellite. The method comprises the following steps: (1) joint debugging of ground test equipment, including conduction and insulation of a ground cable, self-inspection of a measurement and control interface unit, array and ground centralized power supply access inspection and charge and discharge access inspection; (2) performing automatic test initialization, and performing initialization operation on each part of equipment; (3) static interface inspection among the devices, including interface inspection of ground and satellite-borne devices; (4) connecting test cables including a satellite-ground cable and a test cable between satellite-borne equipment; and (5) carrying out joint test function check in a mode of carrying out automatic test by adopting an automatic test sequence, interpreting data in real time, and finally exporting a test result. Compared withthe traditional test method, the automatic test method has the advantages that the test time is greatly shortened, the test items are complete, the test process is clear, and the operability is high.

Description

Problems solved by technology

[0004] At present, the composition of the high-power power supply system for high-orbit communication satellites is relatively complex, and the interfaces of each stand-alone machine in the sub-system are not uniform. The same stand-alone machine even has multiple production units, and the interface design at the sub-system level cannot fully verify the system performance.
