Abstract

A fault management system using a satellite telemetering technology and a method thereof are provided. The fault management system includes: a telemetering sensing unit for collecting telemetering data from target apparatuses, which are installed at a remote location and an unattended location and managed through a satellite, in real time and sensing whether the target apparatuses are malfunctioned or not based on the collected telemetering data; a controlling unit for determining whether the target apparatuses are malfunctioned or not by comparing the telemetering data with unique performance request values for normally driving the target apparatuses, analyzing causes of malfunctions, and storing malfunction data into a malfunction data storing unit; a malfunction data analysis unit for managing the malfunction data stored in the malfunction data storing unit and analyzing the malfunction data; and a display unit for outputting the result of analyzing the malfunction data on a display device.

Claims

1. A fault management system using a satellite telemetering technology comprising:

a telemetering sensing means for collecting telemetering data from target apparatuses, which are installed at a remote location and an unattended location and managed through a satellite, in real time and sensing whether the target apparatuses are malfunctioned or not based on the collected telemetering data;

a controlling means for determining whether the target apparatuses are malfunctioned or not by comparing the telemetering data with unique performance request values for normally driving the target apparatuses, analyzing causes of malfunctions, and storing malfunction data into a malfunction data storing means;

a malfunction data analysis means for managing the malfunction data stored in the malfunction data storing means and analyzing the malfunction data; and

a display means for outputting the result of analyzing the malfunction data on a display device.

2. The fault management system as recited in claim 1, further comprising:

a communicating means for enabling the result of analyzing the malfunction data on an external display device.

3. The fault management system as recited in claim 1, wherein the telemetering sensing means supports bidirectional interactive communication in order to check whether the target apparatus is in a normal state or an abnormal state through the satellite by a request from a manager.

4. The fault management system as recited in claim 3, wherein the controlling means includes:

a data examining means for examines a validity of telemetering data received from the telemetering sensing means in real time, and transforming the received telemetering data to data format that denotes the performance state of the target apparatuses;

a data comparison/analysis means for analyzing the performance state data of the target apparatus by comparing the performance state data of the target apparatuses with previously-stored unique assigned values of each elements and part/accessory of each target apparatus;

a data determining means for determining whether performance of each target apparatus or each part/accessory in the target apparatus is in a normal state or an abnormal based on the comparing/analyzing result, transferring information about overall malfunction state or partial malfunction state of the part/accessory of the target apparatus with position information of the apparatus to the display means; and

a malfunction data storing unit for receiving the malfunction state information of the target apparatus and the telemetering data from the telemetering sensing means, transforming the received malfunction state information and the telemetering data to malfunction data in real time, and storing the malfunction data.

5. The fault management system as recited in claim 4, wherein the controlling means is an on-board computer that multi-processes the telemetering data from the telemetering sensing means and flexibly managing the telemetering data according to functional expansion of the target apparatus including adding and modifying functions of the target apparatus.

6. The fault management system as recited in claim 5, wherein the malfunction data analyzing means includes:

a malfunction data transforming means for transforming the malfunction data stored in the malfunction data storing means into data format that can be used as an input data of a malfunction statistical analysis tool and a RAMS analysis tool;

an information analysis means for analyzing the transformed data using the statistical malfunction analysis tool or the RAMS analysis tool by performing statistical malfunction analysis, a mean time between failure (MTBF) analysis, reliability analysis, availability analysis, and maintainability analysis of each part/accessory constituting an entire apparatus and target apparatuses, or performing a predetermined analysis in response to an external request; and

a display configuration assigning means for assigning a display configuration to display the analysis result and outputting the analysis result on the display means based on the assigned display configuration through the communicating means.

7. The fault management system as recited in claim 6, wherein the display means outputs the result of determining whether the performance of the target apparatus is in a normal state or an abnormal state transferred from the controlling means on a display device, and outputs the result of analyzing the malfunction data transferred from the malfunction data analysis means.

8. The fault management system as recited in claim 7, wherein a graphic user interface (GUI) is provided to a manager.

9. The fault management system as recited in claim 1, wherein the telemetering data includes position information of target apparatus, an identification number of each part/accessory, a performance state and malfunction state of each part/accessory, and a state of transmission path to the target apparatuses.

10. A fault management method using satellite telemetering technology comprising:

collecting telemetering data from target apparatuses, which are installed at a remote location and an unattended location and managed through a satellite, in real time, and sensing whether the target apparatuses are malfunctioned or not based on the collected telemetering data;

determining whether the target apparatuses are malfunctioned or not by comparing the telemetering data with unique performance request values for normally driving the target apparatuses, analyzing causes of malfunctions, and storing malfunction data into a database;

managing the malfunction data stored in the malfunction data storing means and analyzing the malfunction data; and

outputting the result of performing statistical malfunction analysis on the malfunction data stored in the database.

11. The fault management method as recited in claim 10, wherein the telemetering data includes position information of target apparatus, an identification number of each part/accessory, a performance state and a malfunction state of each part/accessory, and a state of transmission path to the target apparatuses.
