Railroad car condition monitoring/analyzing device and method

A railroad car condition monitoring/analyzing device configured to be connected to a data detection device that measures car data and evaluation data with a sensor mounted on a car, and an input device and an output device that input and output data, the railroad car condition monitoring/analyzing device comprising:

• a car factor estimation unit configured to estimate car factor evaluation data from the car data and the evaluation data;
• an infrastructure factor extraction unit configured to extract infrastructure factor evaluation data from the car data, the evaluation data, and the car factor evaluation data;
• an infrastructure factor estimation unit configured to estimate individual infrastructure factor evaluation data from the infrastructure factor evaluation data;
• an infrastructure factor DB construction unit configured to store the individual infrastructure factor evaluation data in an infrastructure factor database;
• an infrastructure factor analysis unit configured to monitor the individual infrastructure factor evaluation data stored in the infrastructure factor database so as to analyze infrastructure factors;
• and
• a car analysis unit configured to analyze a car condition in consideration of analysis information on the infrastructure factors, wherein
• the infrastructure factor analysis unit is configured to analyze the individual infrastructure factor evaluation data stored in the infrastructure factor database to determine new infrastructure factors, deteriorated infrastructure factors, and removed infrastructure factors, thereby outputting information on the new infrastructure factors including locations and scales to the output device, and receiving an investigation result of the new infrastructure factors including presence/absence, types, names, and actual measurement data from the input device so as to register the investigation result in the infrastructure factor database;
• outputting information on the deteriorated infrastructure factors including deterioration states and maintenance diagnosis to the output device, and receiving an investigation result of the deteriorated infrastructure factors from the input device so as to register the investigation result in the infrastructure factor database;
• and outputting information on the removed infrastructure factors including infrastructure environment and maintenance to the output device, and receiving an investigation result of the removed infrastructure factors from the input device so as to register the investigation result in the infrastructure factor database.
