A dependence relation database (332) stores dependence relation information (33) wherein a dependence relation between each constituting apparatus among a plurality of constituting apparatuses, and an importance degree to represent intensity of the dependence relation are set, with a vehicle formation (10) being a vertex. An apparatus evaluation unit (302) calculates a soundness estimation value to represent soundness of a terminal constituting apparatus that does not have a constituting apparatus whereon the own constituting apparatus depends among the plurality of constituting apparatuses. A formation evaluation unit (303) acquires the dependence relation information (33), and by using a soundness estimation value of each constituting apparatus among the plurality of constituting apparatuses including the soundness estimation value of the terminal constituting apparatus, and an importance degree of the dependence relation, calculates a soundness estimation value in consideration of the importance degree of the dependence relation of an evaluation target apparatus that is a constituting apparatus being an evaluation target among the plurality of constituting apparatuses, which has a constituting apparatus whereon the own evaluation target apparatus depends.

Distance measurement means measures a distance from a measurement point to a construction gauge in a route of a track. A range identification unit identifies whether or not a measurement point falls within a predetermined range from the construction gauge based on the measured distance. A ground feature identification unit identifies whether or not the measurement point is a measurement point of a feature on a ground. Drawing means draws in a plan view a measurement point identified as a measurement point of a feature on the ground by the ground feature identification unit among the measurement points, and draws in side views a measurement point identified as not a measurement point of a feature on the ground. The drawing means performs different drawing processes on a measurement point identified as falling within the predetermined range from the construction gauge among the measurement points and on a measurement point identified as not falling within the predetermined range from the construction gauge among the measurement points.

In a train interior monitoring method, in order to improve the efficiency in memory-usage, when an event occurs, data containing image information, which has been recorded in a temporary image memory, is recorded in an image memory without any processing in order to reduce the file size of the data. Further, data containing image information is recorded in the image memory represents for only a period of time before and after detection of the occurrence of the event, the period of time being set according to what the event is. After a given period of time has elapsed, the data containing the image information is processed in order to reduce its file size and then recorded in the image memory.
