Apparatus and method for diagnosing fault and managing data in satellite ground system
First Claim
1. An apparatus for diagnosing fault and processing data of a satellite ground system, comprising:
- a satellite data processing and controlling means for processing and analyzing data transmitted from a satellite and performing control required for the satellite;
a signal transforming means for transforming a signal transmitted from the satellite and transmitting the transformed signal to the satellite ground system;
a fault detecting and controlling means for detecting fault by comparing a signal from the satellite data processing and controlling means, all data from the signal transforming means, and a state of each device with each other, and transmitting fault detect contents;
a state displaying means for displaying a state of the satellite and the system by displaying a state of the satellite data processing and controlling means, and the fault detecting and controlling means;
a penalty managing means which is notified whether the device has fault or not from the fault detecting and controlling means and processing the data based on a penalty value;
a data storing means for storing the data when an error is found by the fault detecting and controlling means, and transmitting the data based on a fault state; and
a system recovery supporting means for performing a recovery process when fault is declared in the fault detecting and controlling means.

Abstract
Provided are an apparatus and a method for diagnosing fault and processing data of a satellite ground system. The apparatus and a method can prevent data loss of a satellite, and efficiently operate the satellite ground system using data buffer and penalty method when a temporary fault occurs. Data buffer stores data in fault situation and penalty method imposes high penalty in critical fault and low penalty in minor fault. System is managed according to penalty degree. The apparatus, includes: a satellite data processing and controlling means; a signal transforming means; a fault detecting and controlling means; a state displaying means for displaying a state of the satellite and the system; a penalty managing means for being notified whether the device has fault or not; a data storing means for storing and transmitting the data; and a system recovery supporting means.

8. A method for diagnosing fault and processing data of a satellite ground system, comprising the steps of:
-
a) storing data transmitted from primary and secondary devices of the satellite ground system; b) calculating penalty values in the penalty managing means; c) comparing the penalty values calculated in the step b) with a predetermined fault declaration value T; d) declaring the fault of the device when a penalty value is larger than the fault declaration value T in the step c), transmitting data of a robust device after switching the faulty device and driving the system recovery supporter; and e) checking whether the fault of the device is temporary when the penalty value is not larger than the fault declaration value T in the step c). - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18)
