Claim 7:
8. 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 car analysis unit is configured to calculate infrastructure factor analysis evaluation data based on past infrastructure factor evaluation data stored in the infrastructure factor database, analyze a car condition based on analysis data measured by the data detection device and the infrastructure factor analysis evaluation data in consideration of an influence of a car factor only, and calculate a degree of influence of the infrastructure factors on the analysis data based on the analysis data and the infrastructure factor analysis evaluation data, so as to adjust an operation management for each traveling position including a speed and an acceleration and operating conditions of car instruments including air conditioning and ventilation.
