1. A deterioration diagnosis apparatus comprising:
a processing circuit having a processor and memory,
wherein the memory is configured to include a measurement condition storage unit of the memory in which first measurement conditions are stored, the first measurement conditions being operating conditions of at least one of one or more components and one or more systems of the train under which measurement is performed for diagnosing a state of a device installed on a train;
wherein the processor is configured to include:
a measurement condition determination unit to determine whether or not the first measurement conditions meet second measurement conditions in operation data that is acquired from the train by the processor and includes a measurement result indicating the state of the device installed on the train, the second measurement conditions being operating conditions of at least one of the one or more components and the one or more systems of the train under which the measurement result of the device has been obtained;
a difference condition extraction unit to extract a difference between the first measurement conditions and the second measurement conditions when the measurement condition determination unit determines that there is inconsistency between the first measurement conditions and the second measurement conditions;
a control command generation unit to generate a control command for automated adjustment of an operation level of the at least one of the one or more components and the one or more systems of the train to eliminate the difference in the first and second measurement conditions; and
the processing circuit being further configured to include a control command transmission unit to transmit the control command to the train.
