<P>PROBLEM TO BE SOLVED: To provide an information processing apparatus for monitoring the state of a capacitor during running of a railway vehicle. <P>SOLUTION: A transmission monitoring section 4 collects operation control information showing the current running state of a railway vehicle and the temperature of a capacitor 2 measured by a temperature sensor 1, and outputs the operation control information and the temperature to a state classifying section 5. The state classifying section 5 determines whether the current running state of the railway vehicle and the capacitor temperature shows a state to accumulate a voltage value of the capacitor 2. If the determination is affirmative, the voltage value of the capacitor 2 is read from the voltage sensor 3. Then, a storage processing section 7 causes an apparatus history accumulating section 8 to store the data in a predetermined period by classifying the read voltage values of the capacitor 2 for each railway vehicle speed. A visualizing section 9 displays the accumulated voltages values of the capacitor 2 in a graph for each segments of the railway vehicle speed so as to visually determine the transition of the voltage values of the capacitor 2. <P>COPYRIGHT: (C)2012,JPO&INPIT |
