Data processing apparatus, data processing system, and data processing method

A data processing system in which a plurality of data processing apparatuses are provided in an installation area and that processes data of each installation site and transmits the processed data to a data aggregating apparatus, the data processing system comprising:

• a plurality of calibration nodes that are temporarily installed at mutually different positions to provide self-identification information to the plurality of data processing apparatuses for respectively identifying the plurality of data processing apparatuses and that each transmit to the installation area, calibration information that includes calibration node identification information, respectively identifying a calibration node among the plurality of calibration nodes, and distance information to indicate a distance of the calibration node from each of the plurality of data processing apparatuses;
• and
• a data processing apparatus among the plurality of data processing apparatuses includes:
• a wireless communications circuit that receives the calibration information from the plurality of calibration nodes and performs transmission and reception of data with an adjacent data processing apparatus among the plurality of data processing apparatuses provided in the installation area,
• a processor that generates the self-identification information based upon the calibration information received from a calibration node, from among the calibration nodes,
• the calibration information including a combination of sets of paired calibration node identification information identifying the calibration node and distance information indicating a distance of the data processing apparatus from the calibration node, and
• a memory device that retains the generated self-identification information.
