1. A data collection system comprising:
a monitoring device to sequentially instruct two or more in-vehicle devices installed in a railroad car to start operating and to stop operating, the two or more in-vehicle devices being installed in a plurality of railroad cars; and
an auxiliary power supply to sequentially measure an output voltage and an output current supplied to the two or more in-vehicle devices by the auxiliary power supply while the two or more in-vehicle devices operate in turns in accordance with an instruction from the monitoring device, and record measurement results, and wherein the monitoring device selects one in-vehicle device at a time from the two or more in-vehicle devices based on an instruction order to start operating and stop operating, the instruction order indicating an order of selecting one of the two or more in-vehicle devices installed in the plurality of railroad cars to start operating and stop operating, and wherein the instruction order does not select an other of the two or more in-vehicle devices to start operating and stop operating until each of the selected one of the two or more in-vehicles devices installed in the plurality of railroad cars has been instructed to start operating and stop operating.
