  • a communication section that communicates with the first network and second network respectively;

    a processing section; and

    a memory section, whereinthe processing section extracts event statuses on the basis of the data items received from the plurality of terminal nodes via the communication section, and estimates the communication condition of the second network;

    the processing section selects a compression class for the data items, which should be transmitted to the monitoring center, according to the communication condition of the second network; and

    the processing section determines a priority order of the data items, which should be transmitted, and a compression method on the basis of the event statuses and compression class.
