Data collection system and data collection method

A data collection apparatus configured to collect data transmitted from a plurality of devices having a communication function,

• the data collection apparatus comprising:
• a receiver configured to receive data transmitted from the plurality of devices;
• a data analyzer configured to acquire analyzed data by analyzing the received data according to an analysis data format which is different for each device of the plurality of devices, the analysis data format being predetermined for each type of device of the plurality of devices;
• a first data storage which is a non-rewritable storage;
• a second data storage which is storage that can be accessed faster than the first data storage and that stores a smaller amount of data than the first data storage;
• and
• a data writer configured to write and store the data received by the receiver with a tag attached thereto to the first data storage, and write and store the analyzed data acquired by the data analyzer with the tag attached thereto to the second data storage, the tag being identification information associated with an installation location of the device from which the data is received.
