Abstract

The invention provides a comprehensive diagnosis method and apparatus of receiving faults of a remote sensing satellite ground receiving system. The method comprises: a receiving log collection step:collecting event logs of the ground receiving system in a task receiving process and performing normalization processing on the event logs; a receiving flow mining step: performing receiving flow mining according to the event logs subjected to the normalization processing; a flow diagnosis and analysis step: diagnosing whether a receiving flow obtained in the receiving flow mining step satisfies acorrect receiving flow; a receiving device information collection step: collecting the state information of devices participating in task receiving during task receiving; and a receiving device diagnosis and analysis step: diagnosing whether the devices participating in task receiving run according to correct parameters during the task execution according to a defined fault diagnosis system. By adoption of the comprehensive diagnosis method and apparatus, the receiving tasks of the remote sensing satellite ground receiving system can be automatically diagnosed to find the faults in the receiving process in time, thereby improving the success rate and reducing the manpower and material consumption.

Description

technical field [0001] The invention relates to the field of fault diagnosis, in particular to a method and a diagnostic device for comprehensive diagnosis of task receiving faults of a remote sensing satellite ground receiving system. Background technique [0002] The remote sensing satellite ground receiving system is the data source of the entire satellite remote sensing application industry, and occupies an important position in the remote sensing satellite ground system. At present, the remote sensing satellite ground receiving system contains a wide variety of equipment, and the equipment in the system is tightly coupled. A fault may cause the system to malfunction and directly affect the reception of satellite data resources. On the other hand, the handling of system failures in my country's receiving stations is heavily dependent on manual intervention, fault diagnosis is not accurate, and equipment disassembly and maintenance are blind, which has caused unnecessary ...
