Data collection system, data output apparatus, and data collection method

A data output apparatus that outputs data in wireless communication, and is used in a state of a plurality of the data output apparatuses being installed at places different from each other, the data output apparatus comprising:

• at least one sensor that generates the data;
• and
• a wireless communication apparatus that transmits the data toward a data storage apparatus, wherein
• the wireless communication apparatus
• stores, for each of the plurality of other wireless communication apparatuses that can be a transmission destination of the data, connection information for connecting to the other wireless communication apparatus and priority information indicating a priority of the other wireless communication apparatus, and
• repeats processing of reading the connection information, and performing communication by using the read connection information in descending order of the priority until the communication succeeds when a transmission route of the data is set,
• wherein the data output apparatus adjusts a volume of the data to be transmitted in response to time since the data transmitted are output until the data transmitted reach the data storage apparatus, wherein the data output apparatus adjusts the volume of data by adjusting a measurement time of the sensor when one piece of the data is generated.

A data collection method comprising using a data collection system, the data collection system comprising:

• a plurality of data output apparatuses that are installed at places different from each other, and each output data in wireless communication, and
• a data storage apparatus that stores the data output from the plurality of data output apparatuses, wherein
• each of the plurality of data output apparatuses comprises
• at least one sensor that generates the data, and
• a wireless communication apparatus that transmits the data toward the data storage apparatus, and
• the wireless communication apparatus
• stores, for each of the plurality of other wireless communication apparatuses that can be a transmission destination of the data, connection information for connecting to the other wireless communication apparatus and priority information indicating a priority of the other wireless communication apparatus, and
• repeats processing of reading the connection information, and processing communication by using the read connection information in descending order of the priority until the communication succeeds when a transmission route of the data is set,
• wherein each of the plurality of data output apparatuses adjusts a volume of the data to be transmitted in response to time since the data transmitted are output until the data transmitted reach the data storage apparatus, wherein the data output apparatus adjusts the volume of data by adjusting a measurement time of the sensor when one piece of the data is generated.
