the terminal;
the data collection unit,
wherein the terminal includes a detection unit other than a sensor device that detects sensing data and instrument information, and stores metadata that is information detected by the detection unit in an extended field specified by the one or the plurality of communication protocols within a frame specified by the one or the plurality of communication protocols for transmitting the sensing data or the instrument information, and
the data collection unit associates in a database the sensing data, the instrument information, and the metadata with each other based on information for identifying the terminal described in the frame; and
