According to the troubleshooting requirements of FY3 meteorological satellites data acquisition in domestic and oversea ground stations, a remote fault diagnosis system is developed by means of Java 16 in the Eclipse 36 platform. The general framework is analyzed, and the workflow is introduced. The system can realize the remote and centralized monitoring of equipment running status in ground stations, trigger automatic fault diagnosis and rulebased fault diagnosis by parsing the quality logs, generate trouble tickets and import the expert experience database, and provide text and graphics query methods. Through the practical verification, it is proved that the system can assist knowledge engineers in remote, precise and rapid fault location with a friendly graphical user interface, boost the fault diagnosis efficiency, and enhance the remote monitoring capability of the integrity operating control system. The system has a certain practical significance to improve the quality of FY3 meteorological satellites data acquisition.
