Field: Transport (Mechanical engineering)
Classification: CPC B  H | IPC B

Claim 12:
13. A car monitoring system comprising:
a sub-system configured to execute a predetermined function by controlling at least one instrument mounted on a railcar; and
a monitoring device configured to monitor an operating state of the sub-system, wherein:
the sub-system includes
a sub-system controller configured to create status data containing pieces of event information based on a signal output from the instrument and periodically transmit the status data to the monitoring device, the pieces of event information informing the monitoring device of a change in state of the instrument; and
a first memory configured to store a first event parameter file which defines a data structure of an event region of the status data, the event region being a region in which the pieces of event information are stored,

the monitoring device includes
a second memory configured to store the status data received from the sub-system controller and a second event parameter file defining the data structure of the event region contained in the status data; and
a monitoring device controller configured to monitor the operating state of the sub-system based on the status data,

when the first event parameter file is changed, and the sub-system controller creates the status data, the sub-system controller reconstructs the data structure of the event region based on the changed first event parameter file and resets the pieces of event information in accordance with the reconstructed data structure, and
when the second event parameter file is changed, and the monitoring device controller monitors the operating state of the sub-system, the monitoring device controller reconstructs the data structure of the event region based on the changed second event parameter file and interprets the pieces of event information in accordance with the reconstructed data structure.
